+! Turning on "installColormap" interacts erratically with twm and tvtwm,
+! but seems to work fine with mwm and olwm. Try it and see. If your
+! screen turns some color other than black, the window manager is buggy,
+! and you need to set this resource to False (or get a WM that works.)
+!
+*installColormap: True
+
+
+! Any program which can draw on the root window will work as a screensaver.
+! The following resource enumerates them.
+!
+! Programs are separated by newlines (specified in resource files with \n).
+! Lines may be continued with a lone \ at the end of the line.
+!
+! Each line is an `sh' command.
+!
+! But, if the first word on the line is the name of a visual followed by a
+! colon, then that visual will be used for the program, if it is available.
+! If no such visual is available, then the program will be skipped. In
+! this way, you can specify that you want certain programs to run only
+! on color screens, and others only on mono screens, by making use of the
+! magic visual names "color" and "mono". Likewise, if some hacks prefer
+! colormaps, but others prefer 24-bit windows, that also can be arranged
+! (in this case, by using "PseudoColor:" versus "TrueColor:".)
+!
+! All programs must be launched in such a way that they draw on the root
+! window; they should not be spawned in the background with "&". If shell
+! metacharacters are used, they must be understandable to `sh', not `csh'
+! (the $SHELL variable is not consulted, for unfortunate but good reasons.)

+
+! A few of the hacks require OpenGL, and will only be built if you have it.
+! Note that those hacks (gears, superquadratics, escher, pipes, and
+! sproingies) will work best on a visual *half* as deep as the depth of the
+! screen, since that way they can do double-buffering -- on an SGI, you
+! should specify the 12-bit TrueColor visual (probably 0x29) instead of
+! letting XScreenSaver pick the visual itself (specifying "TrueColor" would
+! select the 24-bit TrueColor visual, and double-buffering wouldn't be used,
+! resulting in flicker.)
+!
+! Some other programs that you might want to track down (these work as
+! XScreenSaver helpers, but are not distributed with it):
+!
+! xdaliclock -root -builtin2 \n\
+! xswarm -r 2>&- \n\
+! xwave -root \n\
+! xbouncebits ... \n\
+! ico -r -faces -sleep 1 -obj ico \n\
+! xsplinefun \n\
+! kaleid -root \n\
+! color: xfishtank -c black -d -r 2 \n\
+!
+! xtacy is ok, but it only works on the default visual. We can satisfy
+! that constraint like so:
+!
+! default: xtacy -root -delay 100 -funky -number 3 \n\
+! default: xtacy -root -delay 100 -gravity \n\
+! default: xtacy -root -delay 100 -mixer \n\
+! default: xtacy -root -delay 100 -taffy -pal 4 \n\
+!
+! To display a slideshow of images, you can do something like this:
+!
+! default: xv -root -rmode 5 image-1.gif -quit
+! default: xv -root -rmode 5 image-2.gif -quit
+! default: xv -root -rmode 5 image-3.gif -quit
+! ...and so on...
+!
+! however, for this to work, you must also have started the screensaver so
+! that it uses the default colormap (the "-no-install" command-line option, or
+! the "installColormap: False" resource) because when XV is running in "-root"
+! mode, it always assumes that the default colormap is being used, rather than
+! examining the window it is drawing on to see what colormap it has. (It
+! also assumes the default visual, but we've taken care of that above.)
+!
+! Some SGI GL programs work with XScreenSaver; most don't.
+!
+! Bongo works fine:
+!
+! /usr/demos/bin/bongo -wbongo
+!
+! ElectroPaint sort-of works; XScreenSaver will launch it, and it will run
+! properly, but when it's time to turn off the screensaver, you need to hit
+! the Escape key, rather than just moving the mouse. Apparently GL programs
+! are able to intercept the keyboard even when X has the keyboard grabbed!
+!
+! /usr/demos/bin/ep
+!
+! None of the other SGI GL demos I've tried worked, because none of them seem
+! to have command-line options that will make them take up the whole screen;
+! so all you get is a miniscule 100x100 image, which is worthless. This is a
+! shame, since many of those demos would make fine screensavers.
+!
+! If anyone who understands how "haven" works would like to send me the code
+! necessary to do what it does, I would be much obliged.

+ The _\ba_\bt_\bt_\br_\ba_\bc_\bt_\bi_\bo_\bn program has several visually different
+ modes of operation, all of which are based on the interac-
+ tions of a set of control points which attract each other
+ up to a certain distance, and then begin to repel each
+ other. The attraction/repulsion is proportional to the
+ distance between any two particles.
+

+ _\ba_\bt_\bt_\br_\ba_\bc_\bt_\bi_\bo_\bn accepts the following options:
+
+ -\b-w\bwi\bin\bnd\bdo\bow\bw Draw on a newly-created window. This is the
+ default.
+
+ -\b-r\bro\boo\bot\bt Draw on the root window.
+
+ -\b-m\bmo\bon\bno\bo If on a color display, pretend we're on a
+ monochrome display.
+
+ -\b-i\bin\bns\bst\bta\bal\bll\bl
+ Install a private colormap for the window.
+
+ -\b-v\bvi\bis\bsu\bua\bal\bl _\bv_\bi_\bs_\bu_\ba_\bl
+ Specify which visual to use. Legal values are the
+ name of a visual class, or the id number (decimal
+ or hex) of a specific visual.
+
+ -\b-p\bpo\boi\bin\bnt\bts\bs i\bin\bnt\bte\beg\bge\ber\br
+ How many control points should be used, or 0 to
+ select the number randomly. Default 0. Between 3
+ and 15 works best.
+
+ -\b-t\bth\bhr\bre\bes\bsh\bho\bol\bld\bd i\bin\bnt\bte\beg\bge\ber\br
+ The distance (in pixels) from each particle at
+ which the attractive force becomes repulsive.
+ Default 100.
+
+ -\b-m\bmo\bod\bde\be b\bba\bal\bll\bls\bs |\b| l\bli\bin\bne\bes\bs |\b| p\bpo\bol\bly\byg\bgo\bon\bns\bs |\b| t\bta\bai\bil\bls\bs |\b| s\bsp\bpl\bli\bin\bne\bes\bs |\b| f\bfi\bil\bll\ble\bed\bd-\b-

+ In _\bb_\ba_\bl_\bl_\bs mode (the default) the control points are
+ drawn as filled circles. The larger the circle,

+
+
+X Version 11 14-Jun-97 1
+
+
+
+
+
+XScreenSaver(1) XScreenSaver(1)
+
+
+ the more massive the particle.
+
+ In _\bl_\bi_\bn_\be_\bs mode, the control points are connected by
+ straight lines; the effect is something like _\bq_\bi_\bx.
+
+ In _\bp_\bo_\bl_\by_\bg_\bo_\bn_\bs mode, the control points are connected
+ by straight lines, and filled in. This is most
+ interesting in color.
+
+ In _\bs_\bp_\bl_\bi_\bn_\be_\bs mode, a closed spline is interpolated
+ from the control points.
+
+ In _\bf_\bi_\bl_\bl_\be_\bd_\b-_\bs_\bp_\bl_\bi_\bn_\be_\bs mode, the splines are filled in
+ instead of being outlines. This is most interest-
+ ing in color.
+
+ In _\bt_\ba_\bi_\bl_\bs mode, the path which each particle fol-
+ lows is indicated by a worm-like trail, whose
+ length is controlled by the _\bs_\be_\bg_\bm_\be_\bn_\bt_\bs parameter.
+
+ -\b-s\bsi\biz\bze\be i\bin\bnt\bte\beg\bge\ber\br
+ The size of the balls in pixels, or 0, meaning to
+ select the sizes randomly (the default.) If this
+ is specified, then all balls will be the same
+ size. This option has an effect in all modes,
+ since the ``size'' of the balls controls their
+ mass.
+
+ -\b-s\bse\beg\bgm\bme\ben\bnt\bts\bs i\bin\bnt\bte\beg\bge\ber\br
+ If in _\bl_\bi_\bn_\be_\bs or _\bp_\bo_\bl_\by_\bg_\bo_\bn_\bs mode, how many sets of
+ line segments or polygons should be drawn. Default
+ 100. This has no effect in _\bb_\ba_\bl_\bl_\bs mode. If _\bs_\be_\bg_\b-
+ _\bm_\be_\bn_\bt_\bs is 0, then no segments will ever be erased
+ (this is only useful in color.)
+
+ -\b-d\bde\bel\bla\bay\by m\bmi\bic\bcr\bro\bos\bse\bec\bco\bon\bnd\bds\bs
+ How much of a delay should be introduced between
+ steps of the animation. Default 10000, or about
+ 0.01 seconds.
+
+ -\b-c\bco\bol\blo\bor\br-\b-s\bsh\bhi\bif\bft\bt i\bin\bnt\bt
+ If on a color display, the color of the line seg-
+ ments or polygons will cycle through the color
+ map. This specifies how many lines will be drawn
+ before a new color is chosen. (When a small num-
+ ber of colors are available, increasing this value
+ will yield smoother transitions.) Default 3.
+ This has no effect in _\bb_\ba_\bl_\bl_\bs mode.
+
+ -\b-r\bra\bad\bdi\biu\bus\bs The size in pixels of the circle on which the
+ points are initially positioned. The default is
+ slightly smaller than the size of the window.
+
+ -\b-g\bgl\blo\bow\bw This is consulted only in _\bb_\ba_\bl_\bl_\bs mode. If this is

+
+
+X Version 11 14-Jun-97 2

+
+
+ specified, then the saturation of the colors of
+ the points will vary according to their current
+ acceleration. This has the effect that the balls
+ flare brighter when they are reacting to each
+ other most strongly.
+
+ In _\bg_\bl_\bo_\bw mode, all of the balls will be drawn the
+ same (random) color, modulo the saturation shifts.
+ In non-glow mode, the balls will each be drawn in
+ a random color that doesn't change.
+
+ -\b-n\bno\bog\bgl\blo\bow\bw Don't do ``glowing.'' This is the default.
+
+ -\b-v\bvx\bx p\bpi\bix\bxe\bel\bls\bs
+
+ -\b-v\bvy\by p\bpi\bix\bxe\bel\bls\bs
+ Initial velocity of the balls. This has no effect
+ in -\b-o\bor\brb\bbi\bit\bt mode.
+
+ -\b-o\bor\brb\bbi\bit\bt Make the initial force on each ball be tangential
+ to the circle on which they are initially placed,
+ with the right velocity to hold them in orbit
+ about each other. After a while, roundoff errors
+ will cause the orbit to decay.
+
+ -\b-v\bvm\bmu\bul\blt\bt f\bfl\blo\boa\bat\bt
+ In orbit mode, the initial velocity of the balls
+ is multiplied by this; a number less than 1 will
+ make the balls pull closer together, and a larger
+ number will make them move apart. The default is
+ 0.9, meaning a slight inward pull.
+
+ -\b-v\bvi\bis\bsc\bco\bos\bsi\bit\bty\by f\bfl\blo\boa\bat\bt
+ This sets the viscosity of the hypothetical fluid
+ through which the control points move; the default
+ is 1, meaning no resistance. Values higher than 1
+ aren't interesting; lower values cause less
+ motion.
+
+ One interesting thing to try is
+
+ attraction -viscosity 0.8 -points 75 \
+ -mouse -geometry =500x500
+
+ Give it a few seconds to settle down into a stable
+ clump, and then move the mouse through it to make
+ "waves".
+
+ -\b-m\bmo\bou\bus\bse\be This will cause the mouse to be considered a con-
+ trol point; it will not be drawn, but it will
+ influence the other points, so you can wave the
+ mouse and influence the images being created.

+ The _\bb_\bl_\bi_\bt_\bs_\bp_\bi_\bn program repeatedly rotates a bitmap by 90
+ degrees by using logical operations: the bitmap is divided
+ into quadrants, and the quadrants are shifted clockwise.
+ Then the same thing is done again with progressively
+ smaller quadrants, except that all sub-quadrants of a
+ given size are rotated in parallel. So this takes
+ O\bO(\b(1\b16\b6*\b*l\blo\bog\bg2\b2(\b(N\bN)\b))\b) blits of size NxN, with the limitation that
+ the image must be square, and the size must be a power of
+ 2.

+ _\bb_\bl_\bi_\bt_\bs_\bp_\bi_\bn accepts the following options:

+ If support for the _\bX_\bP_\bM library was enabled at com-

+ _\bB_\bu_\bb_\bb_\bl_\be_\bs sprays lots of little random bubbles all over the
+ window which then grow until they reach their maximum size
+ and go pop. The inspiration for this was watching little
+ globules of oil on the bottom of a frying pan and it also
+ looks a little like bubbles in fizzy soft drink. The
+ default mode uses fancy ray-traced bubbles but there is
+ also a mode which just draws circles in case the default
+ mode is too taxing on your hardware.

+
+ -\b-s\bsi\bim\bmp\bpl\ble\be Don't use the default fancy pixmap bubbles. Just
+ draw circles instead. This may give more bearable
+ performance if your hardware wasn't made for this
+ sort of thing.
+
+ -\b-b\bbr\bro\bok\bke\ben\bn Don't hide bubbles when they pop. This was a bug
+ during development but the results were actually
+ quite attractive. (This option is only available
+ if you have the XPM library available and the
+ imake generated Makefile has defined HAVE_XPM).
+
+ -\b-3\b3D\bD Normally, the simulation is done completely in two
+ dimensions. When a bubble swallows up another
+ bubble, the areas of each are added to get the
+ area of the resulting bubble. This option changes
+ the algorithm to instead add volume (imagining
+ each to be a sphere in 3D space). The whole thing
+ looks more realistic but I find it attracts atten-
+ tion to the flickering of each bubble as they are
+ move and are redrawn. Your mileage may vary.
+
+ -\b-f\bfi\bil\ble\be f\bfi\bil\ble\ben\bna\bam\bme\be
+ Use the pixmap definitions in the given file,
+ instead of the default (if one is compiled in).
+ This is ignored if _\b-_\bs_\bi_\bm_\bp_\bl_\be is specified. If the
+ file is compressed (either with compress or gzip),
+ it is decompressed before use. (This option only
+ works if you have XPM compiled into your binary
+ and you have compiled with BUBBLES_IO set in bub-
+ bles.h. This is n\bno\bot\bt the default).
+
+ -\b-d\bdi\bir\bre\bec\bct\bto\bor\bry\by d\bdi\bir\bre\bec\bct\bto\bor\bry\byn\bna\bam\bme\be
+ Similar to _\b-_\bf_\bi_\bl_\be except the file is taken randomly
+ from the contents of the specified directory.
+ (Again, this option is only available if you have
+ XPM and BUBBLES_IO was set when compiling. See
+ above).
+
+ -\b-q\bqu\bui\bie\bet\bt Don't print messages explaining why one or several
+ command line options were ignored. This is dis-
+ abled by default.
+
+N\bNO\bOT\bTE\bES\bS
+ If you find the pace of things too slow, remember that
+ there is a delay even though you specify no _\b-_\bd_\be_\bl_\ba_\by option.
+ Try using _\b-_\bn_\bo_\bd_\be_\bl_\ba_\by although beware of the effects of irri-
+ tation of other users if you're on a shared system as you
+ bleed their CPU time away.
+
+ Some tools to assist in creation of new bubbles are
+ included in the source distribution. These can either be

+ loaded with the _\b-_\bf_\bi_\bl_\be or _\b-_\bd_\bi_\br_\be_\bc_\bt_\bo_\br_\by options (if available)
+ or they can be used in place of the distributed default
+ bubble (bubble_default.c). You might like to copy these
+ scripts to a permanent location and use them. Read bub-
+ bles.README.
+
+ Rendered bubbles are not supported on monochrome displays.
+ I'm not convinced that small bubbles, even dithered prop-
+ erly are going to look like anything more than a jumble of
+ random dots.
+
+B\bBU\bUG\bGS\bS
+ There is a delay before something appears on the screen
+ when using rendered bubbles. The XPM library seems to
+ take a l\blo\bon\bng\bg time to make pixmaps out of raw data. This
+ can be irritating on slower systems.
+
+ The movement of the bubbles looks jerky if an incomplete
+ set of bubbles is used.
+
+ The hide/display algorithm could do with some work to
+ avoid flickering when _\b-_\bn_\bo_\bd_\be_\bl_\ba_\by is set.

+ The _\bj_\bu_\bl_\bi_\ba program draws spinning, animating julia-set
+ fractals.
+
+ It uses ifs {w0 = sqrt(x-c), w1 = -sqrt(x-c)} with random
+ iteration to plot the julia set, and sinusoidially varied
+ parameters for the set, and plots parameters with a cir-
+ cle.
+
+ One thing to note is that count is the _\bd_\be_\bp_\bt_\bh of the search
+ tree, so the number of points computed is (2^count)-1. I
+ use 8 or 9 on a dx266 and it looks okay. The sinusoidal
+ variation of the parameter might not be as interesting as
+ it could, but it still gives an idea of the effect of the
+ parameter.

+
+ This implementation uses the simpler version of the growth
+ algorithm, i.e., if there are no forced vertices, a ran-
+ domly chosen tile is added to a randomly chosen vertex (no
+ preference for those 108 degree angles).
+
+ There are two essential differences to the algorithm pre-
+ sented in the literature: First, we do not allow the
+ tiling to enclose an untiled area. Whenever this is in
+ danger of happening, we just do not add the tile, hoping
+ for a better random choice the next time. Second, when
+ choosing a vertex randomly, we will take one that lies
+ withing the viewport if available. If this seems to cause
+ enclosures in the forced rule case, we will allow invisi-
+ ble vertices to be chosen.
+
+ Tiling is restarted whenever one of the following happens:
+ there are no incomplete vertices within the viewport or
+ the tiling has extended a window's length beyond the edge
+ of the window horizontally or vertically or forced rule
+ choice has failed 100 times due to areas about to become
+ enclosed.

+
+ -\b-s\bse\beg\bgm\bme\ben\bnt\bts\bs _\bi_\bn_\bt_\be_\bg_\be_\br
+ How many line segments should be drawn. Default
+ 50.
+
+ -\b-s\bsp\bpr\bre\bea\bad\bd _\bi_\bn_\bt_\be_\bg_\be_\br
+ How far apart the endpoints of one segment should
+ be from the next. Default 8.
+
+ -\b-s\bsi\biz\bze\be _\bi_\bn_\bt_\be_\bg_\be_\br
+ The maximum distance one endpoint of a segment is
+ allowed to be from the opposite end of that seg-
+ ment. Default 0, meaning unlimited.

+
+ -\b-c\bco\bol\blo\bor\br-\b-s\bsh\bhi\bif\bft\bt _\bd_\be_\bg_\br_\be_\be_\bs
+ If on a color display, the color of the line seg-
+ ments will cycle through the spectrum. This spec-
+ ifies how far the hue of each segment should be
+ from the next, in degrees on the HSV wheel.
+ Default 3.
+
+ -\b-d\bde\bel\bla\bay\by _\bm_\bi_\bc_\br_\bo_\bs_\be_\bc_\bo_\bn_\bd_\bs
+ How much of a delay should be introduced between
+ steps of the animation. Default 25000, or about
+ 0.025 seconds.
+
+ -\b-r\bra\ban\bnd\bdo\bom\bm The _\bq_\bi_\bx will wander around the screen semi-ran-
+ domly. This is the default.
+
+ -\b-l\bli\bin\bne\bea\bar\br The opposite of _\b-_\br_\ba_\bn_\bd_\bo_\bm: the _\bq_\bi_\bx will travel in
+ straight lines until it reaches a wall, and then
+ it will bounce.
+
+ -\b-s\bso\bol\bli\bid\bd If this is specified, then the area between the
+ line segments will be filled in with the appropri-
+ ate color, instead of the _\bq_\bi_\bx simply being com-
+ posed of one-pixel-wide line segments. This
+ option looks really good in color.
+
+ -\b-h\bho\bol\bll\blo\bow\bw The opposite of _\b-_\bs_\bo_\bl_\bi_\bd; this is the default.
+
+ -\b-x\bxo\bor\br If this is specified, then qix segments will be
+ drawn and erased with xor, instead of being drawn
+ in some color and erased in the background color.
+ This implies _\b-_\bm_\bo_\bn_\bo, in that only two colors can be
+ used.
+
+ -\b-t\btr\bra\ban\bns\bsp\bpa\bar\bre\ben\bnt\bt
+ If this is specified, and _\b-_\bc_\bo_\bu_\bn_\bt is greater than
+ 1, then each qix will be drawn in one color, and
+ when they overlap, the colors will be mixed. This
+ only works on P\bPs\bse\beu\bud\bdo\boC\bCo\bol\blo\bor\br displays. This looks
+ best in conjuction with _\b-_\bs_\bo_\bl_\bi_\bd.
+
+ -\b-n\bno\bon\bn-\b-t\btr\bra\ban\bns\bsp\bpa\bar\bre\ben\bnt\bt
+ Turns off _\b-_\bt_\br_\ba_\bn_\bs_\bp_\ba_\br_\be_\bn_\bt.
+
+ -\b-a\bad\bdd\bdi\bit\bti\biv\bve\be
+ If _\b-_\bt_\br_\ba_\bn_\bs_\bp_\ba_\br_\be_\bn_\bt is specified, then this option
+ means that the colors will be mixed using an addi-
+ tive color model, as if the qixes were projected
+ light. This is the default.
+
+ -\b-s\bsu\bub\bbt\btr\bra\bac\bct\bti\biv\bve\be
+ If _\b-_\bt_\br_\ba_\bn_\bs_\bp_\ba_\br_\be_\bn_\bt is specified, then this option
+ means that the colors will be mixed using a sub-
+ tractive color model, as if the qixes were
+ translucent filters.

+
+ It is useful to run this from a menu; you may wish

+
+ -\b-e\bex\bxi\bit\bt Causes the screensaver process to exit gracefully.

+
+ If the screensaver is run from _\bx_\bd_\bm_\b(_\b1_\b) (that is, it
+ is already running before you log in) then you may
+ want to issue the ``restart'' command from one of

+
+ This program can lock your terminal in order to prevent

+ is merely to display pretty pictures on your screen when

+
+ The benefit that this program has over the combination of

+ must contain exactly one command -- no semicolons,
+ no ampersands.
+
+ When the screensaver starts up, one of these is
+ selected at random, and run. After the _\bc_\by_\bc_\bl_\be
+ period expires, it is killed, and another is
+ selected and run.
+
+ If the value of this resource is empty, then no
+ programs will be run; the screen will simply be
+ made black.
+
+ If the display has multiple screens, then a dif-
+ ferent program will be run for each screen.
+
+ Note that you must escape the newlines; here is an
+ example of how you might set this in your _\b._\bX_\bd_\be_\b-
+ _\bf_\ba_\bu_\bl_\bt_\bs file:
+
+ xscreensaver.programs: \
+ qix -root \n\
+ ico -r -faces -sleep 1 -obj ico \n\
+ xdaliclock -builtin2 -root \n\
+ xv -root -rmode 5 image.gif -quit \n
+
+ To use a program as a screensaver, two things are
+ required: that that program draw on the root win-
+ dow (or be able to be configured to draw on the
+ root window); and that that program understand
+ ``virtual root'' windows, as used by virtual win-
+ dow managers such as _\bt_\bv_\bt_\bw_\bm. (Generally, this is
+ accomplished by just including the _\b"_\bv_\br_\bo_\bo_\bt_\b._\bh_\b"
+
+
+
+X Version 11 31-May-97 6
+
+
+
+
+
+XScreenSaver(1) XScreenSaver(1)
+
+
+ header file in the program's source.)
+
+ If there are some programs that you want to run
+ only when using a color display, and others that
+ you want to run only when using a monochrome dis-
+ play, you can specify that like this:
+
+ mono: mono-program -root \n\
+ color: color-program -root \n\
+
+ More generally, you can specify the kind of visual
+ that should be used for the window on which the
+ program will be drawing. For example, if one pro-
+ gram works best if it has a colormap, but another
+ works best if it has a 24-bit visual, both can be
+ accomidated:
+
+ PseudoColor: cmap-program -root \n\
+ TrueColor: 24bit-program -root \n\
+
+ (This sort of thing used to be accomplished with
+ the _\bc_\bo_\bl_\bo_\br_\bP_\br_\bo_\bg_\br_\ba_\bm_\bs and _\bm_\bo_\bn_\bo_\bP_\br_\bo_\bg_\br_\ba_\bm_\bs resources, but
+ those resources have now been removed; a warning
+ will be issued if they are used.)
+
+ If you specify a particular visual for a program,
+ and that visual does not exist on the screen, then
+ that program will not be chosen to run. This
+ means that on displays with multiple screens of
+ different depths, you can arrange for appropriate
+ hacks to be run on each. For example, if one
+ screen is color and the other is monochrome, hacks
+ that look good in mono can be run on one, and
+ hacks that only look good in color will show up on
+ the other.
+
+
+ Normally you won't need to change the following resources:

+ When it is time to activate the screensaver, a full-screen
+ black window is created on each screen of the display.
+ The window or windows is given the appropriate properties
+ so that, to any subsequently-created programs, it will
+ appear to be a ``virtual root'' window. Because of this,
+ any program which draws on the root window (and which
+ understands virtual roots) can be used as a screensaver.
+
+ When the user becomes active again, the screensaver win-
+ dows are unmapped and the running subprocesses are killed
+ by sending them S\bSI\bIG\bGT\bTE\bER\bRM\bM. This is also how the subpro-
+ cesses are killed when the screensaver decides that it's
+ time to run a different demo: the old one is killed and a
+ new one is launched.
+
+ Before launching a subprocess, _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br stores an
+ appropriate value for $\b$D\bDI\bIS\bSP\bPL\bLA\bAY\bY in the environment that the
+ child will recieve. (This is so that if you start
+ _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br with a _\b-_\bd_\bi_\bs_\bp_\bl_\ba_\by argument, the programs which
+ _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br launches will draw on the same display; and
+ so that the child will end up drawing on the appropriate
+ screen of a multi-headed display.)
+
+ When the screensaver turns off, or is killed, care is
+ taken to restore the ``real'' virtual root window if there
+ is one. Because of this, it is important that you not
+ kill the screensaver process with _\bk_\bi_\bl_\bl _\b-_\b9 if you are run-
+ ning a virtual-root window manager. If you kill it with
+ -9, you may need to restart your window manager to repair
+ the damage. This isn't an issue if you aren't running a
+ virtual-root window manager.

+ You can control a running screensaver process by using the

+ You can run _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br from your xdm session, so that
+ the screensaver will run even when nobody is logged in on
+ the console. Simply add "\b"x\bxs\bsc\bcr\bre\bee\ben\bns\bsa\bav\bve\ber\br &\b&"\b" to your
+ _\b/_\bu_\bs_\br_\b/_\bl_\bi_\bb_\b/_\bX_\b1_\b1_\b/_\bx_\bd_\bm_\b/_\bX_\bs_\be_\bt_\bu_\bp file. Because _\bx_\bd_\bm grabs the key-
+ board, keypresses will not make the screensaver deacti-
+ vate, but any mouse activity will.
+
+ (If your system does not seem to be executing the _\bX_\bs_\be_\bt_\bu_\bp
+ file, you may need to configure it to do so -- the tradi-
+ tional way to do this is to make that file the value of
+ the _\bD_\bi_\bs_\bp_\bl_\ba_\by_\bM_\ba_\bn_\ba_\bg_\be_\br_\b*_\bs_\be_\bt_\bu_\bp resource in the _\bx_\bd_\bm_\b-_\bc_\bo_\bn_\bf_\bi_\bg file.
+ See the man page for x\bxd\bdm\bm(1) for more details.)
+

+ their startup scripts, so that the screensaver will be
+ reinitialized with their private resource settings when
+ they log in.
+
+ It is safe to run this program as root (as _\bx_\bd_\bm is likely
+ to do.) If run as root, _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br changes its effec-
+ tive user and group ids to something safe (like _\b"_\bn_\bo_\bb_\bo_\bd_\by_\b")
+ before connecting to the X server or launching user-speci-
+ fied programs.
+
+ Locking doesn't work if the screensaver is launched by
+ _\bx_\bd_\bm. To get around this, you can run the screensaver from
+ _\bx_\bd_\bm without locking, and kill and restart it from your
+ personal X startup script to enable locking; for example:
+
+ xscreensaver-command -exit ; xscreensaver
+
+
+D\bDE\bEM\bMO\bO M\bMO\bOD\bDE\bE
+ If _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br receives the D\bDE\bEM\bMO\bO ClientMessage, which is
+ done by running the x\bxs\bsc\bcr\bre\bee\ben\bns\bsa\bav\bve\ber\br-\b-c\bco\bom\bmm\bma\ban\bnd\bd program with the
+ -\b-d\bde\bem\bmo\bo option, the screensaver will black the screen and
+ pop up a dialog box from which you can examine and experi-
+ ment with the client programs.
+
+ The dialog box contains a scrolling list, a text field,
+ and a number of buttons.
+
+ Double-clicking on one of the programs in the list will
+ run it. Clicking the mouse again will bring the dialog
+ box back.
+
+ Single-clicking in the list will place the indicated pro-
+ gram and its args in the text field to be edited. Edit
+ the arguments and hit return to run the program with the
+ parameters you have specified. (Note that these are one-

+ time changes and won't be remembered; to make the changes
+ permanent, you need to edit your X resource file.)
+
+ The buttons are:
+
+ R\bRu\bun\bn N\bNe\bex\bxt\bt
+ Clicking this button will run the next program in
+ the list after the currently-selected one, and
+ will scroll around to the top when it reaches the
+ bottom.
+
+ R\bRu\bun\bn P\bPr\bre\bev\bvi\bio\bou\bus\bs
+ Opposite of Run Next; at the top, it scrolls
+ around to the bottom.
+
+ E\bEd\bdi\bit\bt P\bPa\bar\bra\bam\bme\bet\bte\ber\brs\bs
+ This pops up a second dialog box, in which you
+ have the option to interactively change most of
+ the screensaver's operational parameters, such as
+ its timeouts, and whether it should lock the
+ screen. Changing these parameters here will
+ affect only the running _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br process; to
+ make the changes permanent, you need to edit your
+ X resource file.
+
+ E\bEx\bxi\bit\bt D\bDe\bem\bmo\bo M\bMo\bod\bde\be
+ Returns to normal screensaver operation.
+
+ R\bRe\bei\bin\bni\bit\bti\bia\bal\bli\biz\bze\be
+ This causes the X resource database to be re-read,
+ to pick up any changes you might have made. This
+ works by causing the screensaver process to exit
+ and then restart itself with the same command-line
+ arguments. This is just like the _\b-_\br_\be_\bs_\bt_\ba_\br_\bt argu-
+ ment to x\bxs\bsc\bcr\bre\bee\ben\bns\bsa\bav\bve\ber\br-\b-c\bco\bom\bmm\bma\ban\bnd\bd(1) except that when
+ executed from this button, the screensaver will
+ automatically return to demo mode after restart-
+ ing.
+
+B\bBU\bUG\bGS\bS
+ (This is not a bug, but) note that as of release 1.32, the
+ c\bco\bol\blo\bor\brP\bPr\bro\bog\bgr\bra\bam\bms\bs and m\bmo\bon\bno\boP\bPr\bro\bog\bgr\bra\bam\bms\bs resources are no longer
+ used: they have been supplanted by the extended syntax of
+ the p\bpr\bro\bog\bgr\bra\bam\bms\bs resource (see above.)
+
+ Extensions
+ If you are not making use of one of the server
+ extensions (X\bXI\bID\bDL\bLE\bE, S\bSC\bCR\bRE\bEE\bEN\bN_\b_S\bSA\bAV\bVE\bER\bR, or M\bMI\bIT\bT-\b-S\bSC\bCR\bRE\bEE\bEN\bN-\b-
+ S\bSA\bAV\bVE\bER\bR), then it is possible, in rare situations,
+ for _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br to interfere with event propaga-
+ tion and make another X program malfunction. For
+ this to occur, that other application would need
+ to _\bn_\bo_\bt select K\bKe\bey\byP\bPr\bre\bes\bss\bs events on its non-leaf win-
+ dows within the first 30 seconds of their
+
+
+
+X Version 11 31-May-97 10
+
+
+
+
+
+XScreenSaver(1) XScreenSaver(1)
+
+
+ existence, but then select for them later. In
+ this case, that client _\bm_\bi_\bg_\bh_\bt fail to receive those
+ events. This isn't very likely, since programs
+ generally select a constant set of events immedi-
+ ately after creating their windows and then don't
+ change them, but this is the reason that it's a
+ good idea to install and use one of the server
+ extensions instead, to work around this shortcom-
+ ing in the X protocol.
+
+ Machine Load
+ Although this program ``nices'' the subprocesses
+ that it starts, graphics-intensive subprograms can
+ still overload the machine by causing the X server
+ process itself (which is not ``niced'') to suck a
+ lot of cycles. Care should be taken to slow down
+ programs intended for use as screensavers by
+ inserting strategic calls to s\bsl\ble\bee\bep\bp(3) or u\bus\bsl\ble\bee\bep\bp(3)
+ (or making liberal use of any _\b-_\bd_\be_\bl_\ba_\by options which
+ the programs may provide.)
+
+ Also, an active screensaver will cause your X
+ server to be pretty much permanently swapped in;
+ but the same is true of any program that draws
+ periodically, like x\bxc\bcl\blo\boc\bck\bk(1) or x\bxl\blo\boa\bad\bd(1).
+
+ Latency and Responsiveness
+ If the subprocess is drawing too quickly and the
+ connection to the X server is a slow one (such as
+ an X terminal running over a phone line) then the
+ screensaver might not turn off right away when the
+ user becomes active again (the i\bic\bco\bo(1) demo has
+ this problem if being run in full-speed mode).
+ This can be alleviated by inserting strategic
+ calls to X\bXS\bSy\byn\bnc\bc(3) in code intended for use as a
+ screensaver. This prevents too much graphics
+ activity from being buffered up.
+
+ Locking and XDM
+ Locking doesn't work if the screensaver is
+ launched by _\bx_\bd_\bm. The reason for this is that when
+ it is launched by _\bx_\bd_\bm, the screensaver process is
+ owned by some standard user id (such as _\br_\bo_\bo_\bt or
+ _\bd_\ba_\be_\bm_\bo_\bn) instead of the user who is logged in on
+ the console: because the screensaver was started
+ _\bb_\be_\bf_\bo_\br_\be anyone was logged in. In order for the
+ screensaver to prompt for the password of the per-
+ son who had logged in from _\bx_\bd_\bm, it would need to
+ know who that user was, and there is no reliable
+ and safe way to figure that out. (And even if
+ there was, there would be some other security
+ issues here as well.)
+
+ So if you want to use it as a locker, you must
+
+
+
+X Version 11 31-May-97 11
+
+
+
+
+
+XScreenSaver(1) XScreenSaver(1)
+
+
+ start it with your user id. If it has already
+ been started by _\bx_\bd_\bm, you can kill it with x\bxs\bsc\bcr\bre\bee\ben\bn-\b-
+ s\bsa\bav\bve\ber\br-\b-c\bco\bom\bmm\bma\ban\bnd\bd -\b-e\bex\bxi\bit\bt, and then start it again as
+ you.
+
+ Passwords
+ If you get an error message like ``couldn't get
+ password of _\bu_\bs_\be_\br'' then this probably means that
+ you're on a system in which the g\bge\bet\btp\bpw\bwe\ben\bnt\bt(3)
+ library routine can only be effectively used by
+ root. If this is the case, then _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br must
+ be installed as setuid to root. Care has been
+ taken to make this a safe thing to do.
+
+ It also may mean that your system uses shadow
+ passwords instead of the standard _\bg_\be_\bt_\bp_\bw_\be_\bn_\bt inter-
+ face; in that case, you may need to change some
+ options in _\bc_\bo_\bn_\bf_\bi_\bg_\b._\bh and recompile.
+
+ TWM and Colormaps
+ The i\bin\bns\bst\bta\bal\bll\blC\bCo\bol\blo\bor\brm\bma\bap\bp option doesn't work very well
+ with the t\btw\bwm\bm(1) window manager and its descen-
+ dants.
+
+ There is a race condition between the screensaver
+ and this window manager, which can result in the
+ screensaver's colormap not getting installed prop-
+ erly, meaning the graphics hacks will appear in
+ essentially random colors. (If the screen goes
+ white instead of black, this is probably why.)
+
+ The m\bmw\bwm\bm(1) and o\bol\blw\bwm\bm(1) window managers don't seem
+ to have this problem. The race condition exists
+ because X apparently does not provide a way for an
+ OverrideRedirect window to have its own colormap,
+ short of grabbing the server (which is neither a
+ good idea, nor really possible with the current
+ design.) What happens is that, as soon as the
+ screensaver installs its colormap, t\btw\bwm\bm responds to
+ the C\bCo\bol\blo\bor\brm\bma\bap\bpN\bNo\bot\bti\bif\bfy\by event that is generated by re-
+ instaling the default colormap. Apparently, t\btw\bwm\bm
+ doesn't _\ba_\bl_\bw_\ba_\by_\bs do this; it seems to do it regu-
+ larly if the screensaver is activated from a menu
+ item, but seems to not do it if the screensaver
+ comes on of its own volition, or is activated from
+ another console. Any thoughts on this problem are
+ welcome...
+
+ XView Clients
+ Apparently there are some problems with XView pro-
+ grams getting confused and thinking that the
+ screensaver window is the real root window even
+ when the screensaver is not active: ClientMessages
+ intended for the window manager are sent to the
+
+
+
+X Version 11 31-May-97 12
+
+
+
+
+
+XScreenSaver(1) XScreenSaver(1)
+
+
+ screensaver window instead. This could be solved
+ by making xscreensaver forward all unrecognised
+ ClientMessages to the real root window, but there
+ may be other problems as well. If anyone has any
+ insight on the cause of this problem, please let
+ me know.
+
+ MIT Extension and Fading
+ When using the M\bMI\bIT\bT-\b-S\bSC\bCR\bRE\bEE\bEN\bN-\b-S\bSA\bAV\bVE\bER\bR extension in con-
+ junction with the f\bfa\bad\bde\be option, you may notice an
+ unattractive flicker just before the fade begins.
+ This is because the server maps a black window
+ just before it tells the _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br process to
+ activate. The _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br process immediately
+ unmaps that window, but this results in a flicker.
+ I haven't figured a way to get around this; it
+ seems to be a fundamental property of the (mis-)
+ design of this server extension.
+
+ LessTif (Motif Clone)
+ Rumor has it that demo mode is buggy if XScreen-
+ Saver was compiled with the GNU LessTif reimple-
+ mentation of Motif. Since it works fine with OSF
+ Motif on a variety of systems, I assume these
+ problems are due to bugs in LessTif. Again, any
+ insight would be appreciated.

+.B attraction
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-points \fIint\fP] [\-threshold \fIint\fP] [\-mode balls | lines | polygons | splines | filled-splines | tails ] [\-size \fIint\fP] [\-segments \fIint\fP] [\-delay \fIusecs\fP] [\-color-shift \fIint\fP] [\-radius \fIint\fP] [\-vx \fIint\fP] [\-vy \fIint\fP] [\-glow] [\-noglow] [\-orbit] [\-viscosity \fIfloat\fP] [\-mouse] [\-no-mouse] [\-mouse-size]
+.SH DESCRIPTION
+The \fIattraction\fP program has several visually different modes of
+operation, all of which are based on the interactions of a set of control
+points which attract each other up to a certain distance, and then begin
+to repel each other. The attraction/repulsion is proportional to the
+distance between any two particles.
+.SH OPTIONS
+.I attraction
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window. This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use. Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-points integer
+How many control points should be used, or 0 to select the number randomly.
+Default 0. Between 3 and 15 works best.
+.TP 8
+.B \-threshold integer
+The distance (in pixels) from each particle at which the attractive force
+becomes repulsive. Default 100.
+.TP 8
+.B \-mode "balls | lines | polygons | tails | splines | filled-splines"
+In \fIballs\fP mode (the default) the control points are drawn as filled
+circles. The larger the circle, the more massive the particle.
+
+In \fIlines\fP mode, the control points are connected by straight lines;
+the effect is something like \fIqix\fP.
+
+In \fIpolygons\fP mode, the control points are connected by straight
+lines, and filled in. This is most interesting in color.
+
+In \fIsplines\fP mode, a closed spline is interpolated from the control
+points.
+
+In \fIfilled-splines\fP mode, the splines are filled in instead of being
+outlines. This is most interesting in color.
+
+In \fItails\fP mode, the path which each particle follows is indicated
+by a worm-like trail, whose length is controlled by the \fIsegments\fP
+parameter.
+.TP 8
+.B \-size integer
+The size of the balls in pixels, or 0, meaning to select the sizes
+randomly (the default.) If this is specified, then all balls will be
+the same size. This option has an effect in all modes, since the ``size''
+of the balls controls their mass.
+.TP 8
+.B \-segments integer
+If in \fIlines\fP or \fIpolygons\fP mode, how many sets of line segments
+or polygons should be drawn. Default 100. This has no effect in \fIballs\fP
+mode. If \fIsegments\fP is 0, then no segments will ever be erased (this
+is only useful in color.)
+.TP 8
+.B \-delay microseconds
+How much of a delay should be introduced between steps of the animation.
+Default 10000, or about 0.01 seconds.
+.TP 8
+.B \-color-shift int
+If on a color display, the color of the line segments or polygons will
+cycle through the color map. This specifies how many lines will be drawn
+before a new color is chosen. (When a small number of colors are available,
+increasing this value will yield smoother transitions.) Default 3.
+This has no effect in \fIballs\fP mode.
+.TP 8
+.B \-radius
+The size in pixels of the circle on which the points are initially positioned.
+The default is slightly smaller than the size of the window.
+.TP 8
+.B \-glow
+This is consulted only in \fIballs\fP mode. If this is specified, then
+the saturation of the colors of the points will vary according to their
+current acceleration. This has the effect that the balls flare brighter
+when they are reacting to each other most strongly.
+
+In \fIglow\fP mode, all of the balls will be drawn the same (random)
+color, modulo the saturation shifts. In non-glow mode, the balls will
+each be drawn in a random color that doesn't change.
+.TP 8
+.B \-noglow
+Don't do ``glowing.'' This is the default.
+.TP 8
+.B \-vx pixels
+.TP 8
+.B \-vy pixels
+Initial velocity of the balls. This has no effect in \fB\-orbit\fP mode.
+.TP 8
+.B \-orbit
+Make the initial force on each ball be tangential to the circle on which
+they are initially placed, with the right velocity to hold them in orbit
+about each other. After a while, roundoff errors will cause the orbit
+to decay.
+.TP 8
+.B \-vmult float
+In orbit mode, the initial velocity of the balls is multiplied by this;
+a number less than 1 will make the balls pull closer together, and a larger
+number will make them move apart. The default is 0.9, meaning a slight
+inward pull.
+.TP 8
+.B \-viscosity float
+This sets the viscosity of the hypothetical fluid through which the control
+points move; the default is 1, meaning no resistance. Values higher than 1
+aren't interesting; lower values cause less motion.
+
+One interesting thing to try is
+.EX
+attraction -viscosity 0.8 -points 75 \\
+ -mouse -geometry =500x500
+.EE
+Give it a few seconds to settle down into a stable clump, and then move
+the mouse through it to make "waves".
+.TP 8
+.B \-mouse
+This will cause the mouse to be considered a control point; it will not be
+drawn, but it will influence the other points, so you can wave the mouse
+and influence the images being created.
+.TP 8
+.B \-no-mouse
+Turns off \fB\-mouse\fP.
+.TP 8
+.B \-mouse-size integer
+In \fB\-mouse\fP mode, this sets the mass of the mouse (analagously to the
+\fB\-size\fP parameter.)
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8

+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-bitmap \fIfilename\fP] [\-delay \fIusecs\fP] [\-delay2 \fIusecs\fP]
+.SH DESCRIPTION
+The \fIblitspin\fP program repeatedly rotates a bitmap by 90 degrees by
+using logical operations: the bitmap is divided into quadrants, and the
+quadrants are shifted clockwise. Then the same thing is done again with
+progressively smaller quadrants, except that all sub-quadrants of a
+given size are rotated in parallel. So this takes \fBO(16*log2(N))\fP
+blits of size NxN, with the limitation that the image must be square,
+and the size must be a power of 2.
+.SH OPTIONS
+.I blitspin
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window. This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use. Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-bitmap \fIfilename\fP
+The file name of a bitmap to rotate. It need not be square: it
+will be padded with the background color. If unspecified or the
+string \fI(default)\fP, a builtin bitmap is used.
+
+If support for the \fIXPM\fP library was enabled at compile-time,
+the specified file may be in \fIXPM\fP format as well as \fIXBM\fP, and
+thus may be a color image.
+
+The \fB*bitmapFilePath\fP resource will be searched if the bitmap
+name is not a fully-qualified pathname.
+.TP 8
+.B \-grab\-screen
+If this option is specified, then the image which is spun will be grabbed
+from the portion of the screen underlying the blitspin window.
+.PP
+.TP 8
+.B \-delay microseconds
+How long to delay between steps of the rotation process, in microseconds.
+Default is 500000, one-half second.

+.TP 8
+.B \-delay2 microseconds
+How long to delay between each 90-degree rotation, in microseconds.
+Default is 500000, one-half second.

+.SH NAME
+bubbles - frying pan / soft drink simulation
+.SH SYNOPSIS
+.B bubbles
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-simple] [\-broken] [\-3D] [\-file filename] [\-directory directoryname]
+.SH DESCRIPTION
+\fIBubbles\fP sprays lots of little random bubbles all over the window which
+then grow until they reach their maximum size and go pop. The inspiration
+for this was watching little globules of oil on the bottom of a frying pan
+and it also looks a little like bubbles in fizzy soft drink. The default
+mode uses fancy ray-traced bubbles but there is also a mode which just draws
+circles in case the default mode is too taxing on your hardware.
+.SH OPTIONS
+Depending on how your
+.I bubbles
+was compiled, it accepts the following options:
+.TP 8
+.B \-foreground
+Colour of circles if \fI\-simple\fP mode is selected.
+.TP 8
+.B \-background
+Colour of window background.
+.TP 8
+.B \-window
+Draw on a newly-created window. This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use. Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-delay microseconds
+How much of a delay should be introduced between steps of the animation.
+Default 1, or about 1 microsecond. Actually, this is the delay between each
+group of 15 new bubbles since such a delay between each step results in a
+very slow animation rate.
+.TP 8
+.B \-nodelay
+Same as \fI\-delay 0\fP.
+.TP 8
+.B \-simple
+Don't use the default fancy pixmap bubbles. Just draw circles instead.
+This may give more bearable performance if your hardware wasn't made for
+this sort of thing.
+.TP 8
+.B \-broken
+Don't hide bubbles when they pop. This was a bug during development
+but the results were actually quite attractive. (This option is only
+available if you have the XPM library available and the imake generated
+Makefile has defined HAVE_XPM).
+.TP 8
+.B \-3D
+Normally, the simulation is done completely in two dimensions. When a
+bubble swallows up another bubble, the areas of each are added to get
+the area of the resulting bubble. This option changes the algorithm
+to instead add volume (imagining each to be a sphere in 3D space). The
+whole thing looks more realistic but I find it attracts attention to
+the flickering of each bubble as they are move and are redrawn. Your
+mileage may vary.
+.TP 8
+.B \-file filename
+Use the pixmap definitions in the given file, instead of the default (if
+one is compiled in). This is ignored if \fI\-simple\fP is specified. If
+the file is compressed (either with compress or gzip), it is decompressed
+before use. (This option only works if you have XPM compiled into your
+binary and you have compiled with BUBBLES_IO set in bubbles.h. This is
+\fBnot\fP the default).
+.TP 8
+.B \-directory directoryname
+Similar to \fI-file\fP except the file is taken randomly from the
+contents of the specified directory. (Again, this option is only available
+if you have XPM and BUBBLES_IO was set when compiling. See above).
+.TP 8
+.B \-quiet
+Don't print messages explaining why one or several command line options
+were ignored. This is disabled by default.
+.SH NOTES
+If you find the pace of things too slow, remember that there is a delay
+even though you specify no \fI\-delay\fP option. Try using \fI\-nodelay\fP
+although beware of the effects of irritation of other users if you're on a
+shared system as you bleed their CPU time away.
+
+Some tools to assist in creation of new bubbles are included in the source
+distribution. These can either be loaded with the \fI\-file\fP or
+\fI\-directory\fP options (if available) or they can be used in place
+of the distributed default bubble (bubble_default.c).
+You might like to copy these scripts to a permanent location and
+use them. Read bubbles.README.
+
+Rendered bubbles are not supported on monochrome displays. I'm not
+convinced that small bubbles, even dithered properly are going to look
+like anything more than a jumble of random dots.
+.SH BUGS
+There is a delay before something appears on the screen when using
+rendered bubbles. The XPM library seems to take a \fBlong\fP time to make
+pixmaps out of raw data. This can be irritating on slower systems.
+
+The movement of the bubbles looks jerky if an incomplete set of bubbles
+is used.
+
+The hide/display algorithm could do with some work to avoid flickering
+when \fI\-nodelay\fP is set.

+
+.SH DESCRIPTION
+The \fIjulia\fP program draws spinning, animating julia-set fractals.
+
+It uses ifs {w0 = sqrt(x-c), w1 = -sqrt(x-c)} with random iteration
+to plot the julia set, and sinusoidially varied parameters for the set,
+and plots parameters with a circle.
+
+One thing to note is that count is the \fIdepth\fP of the search tree,
+so the number of points computed is (2^count)-1. I use 8 or 9 on a
+dx266 and it looks okay. The sinusoidal variation of the parameter
+might not be as interesting as it could, but it still gives an idea
+of the effect of the parameter.

+
+.SH DESCRIPTION
+The \fIpenrose\fP program draws quasiperiodic tilings.
+
+See Onoda, Steinhardt, DiVincenzo and Socolar in
+Phys. Rev. Lett. 60, #25, 1988 or
+Strandburg in Computers in Physics, Sep/Oct 1991.
+
+This implementation uses the simpler version of the growth
+algorithm, i.e., if there are no forced vertices, a randomly chosen
+tile is added to a randomly chosen vertex (no preference for those
+108 degree angles).
+
+There are two essential differences to the algorithm presented in
+the literature: First, we do not allow the tiling to enclose an
+untiled area. Whenever this is in danger of happening, we just
+do not add the tile, hoping for a better random choice the next
+time. Second, when choosing a vertex randomly, we will take
+one that lies withing the viewport if available. If this seems to
+cause enclosures in the forced rule case, we will allow invisible
+vertices to be chosen.
+
+Tiling is restarted whenever one of the following happens: there
+are no incomplete vertices within the viewport or the tiling has
+extended a window's length beyond the edge of the window
+horizontally or vertically or forced rule choice has failed 100
+times due to areas about to become enclosed.

+.SH DESCRIPTION
+The \fIqix\fP program bounces a series of line segments around its window.
+This is truly the swiss army chainsaw of qix programs. If you know of one
+with more display modes, I want to know about it.
+.SH OPTIONS
+.I qix
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window. This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use. Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-segments \fIinteger\fP
+How many line segments should be drawn. Default 50.
+.TP 8
+.B \-spread \fIinteger\fP
+How far apart the endpoints of one segment should be from the next.
+Default 8.
+.TP 8
+.B \-size \fIinteger\fP
+The maximum distance one endpoint of a segment is allowed to be from
+the opposite end of that segment. Default 0, meaning unlimited.
+.TP 8
+.B \-count \fIinteger\fP
+How many qixes to draw. Default 1.
+.TP 8
+.B \-color\-shift \fIdegrees\fP
+If on a color display, the color of the line segments will cycle through
+the spectrum. This specifies how far the hue of each segment should be
+from the next, in degrees on the HSV wheel. Default 3.
+.TP 8
+.B \-delay \fImicroseconds\fP
+How much of a delay should be introduced between steps of the animation.
+Default 25000, or about 0.025 seconds.
+.TP 8
+.B \-random
+The \fIqix\fP will wander around the screen semi-randomly. This is the
+default.
+.TP 8
+.B \-linear
+The opposite of \fI\-random\fP: the \fIqix\fP will travel in straight lines
+until it reaches a wall, and then it will bounce.
+.TP 8
+.B \-solid
+If this is specified, then the area between the line segments will be filled
+in with the appropriate color, instead of the \fIqix\fP simply being composed
+of one-pixel-wide line segments. This option looks really good in color.
+.TP 8
+.B \-hollow
+The opposite of \fI\-solid\fP; this is the default.
+.TP 8
+.B \-xor
+If this is specified, then qix segments will be drawn and erased with xor,
+instead of being drawn in some color and erased in the background color.
+This implies \fI\-mono\fP, in that only two colors can be used.
+.TP 8
+.B \-transparent
+If this is specified, and \fI\-count\fP is greater than 1, then each qix
+will be drawn in one color, and when they overlap, the colors will be mixed.
+This only works on \fBPseudoColor\fP displays. This looks best in
+conjuction with \fI\-solid\fP.
+.TP 8
+.B \-non\-transparent
+Turns off \fI\-transparent\fP.
+.TP 8
+.B \-additive
+If \fI\-transparent\fP is specified, then this option means that the colors
+will be mixed using an additive color model, as if the qixes were projected
+light. This is the default.
+.TP 8
+.B \-subtractive
+If \fI\-transparent\fP is specified, then this option means that the
+colors will be mixed using a subtractive color model, as if the qixes were
+translucent filters.
+.TP 8
+.B \-poly \fIint\fP
+How many vertices each qix-line should have: the default is 2, meaning the
+traditional qix line shape. Three will yield triangles, and so on.
+.TP 8
+.B \-gravity
+.TP 8
+.B \-no\-gravity
+Whether there should be downward attraction. For example, the
+options
+.B \-gravity \-linear
+will make everything move in nice smooth parabolas.
+Gravity is off by default.

+.SH NAME
+rocks - animation of flying through an asteroid field
+.SH SYNOPSIS
+.B rocks
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-install] [\-visual \fIvisual\fP] [\-count \fIinteger\fP] [\-delay \fIusecs\fP] [\-speed \fIinteger\fP] [\-norotate] [\-nomove] [\-3d]
+.SH DESCRIPTION
+The \fIrocks\fP program draws an animation of an asteroid field moving past
+the observer (or vice versa). Sometimes the observer picks up spin on Z axis.
+.SH OPTIONS
+.I rocks
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window. This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use. Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-count \fIinteger\fP
+Maximum number of rocks to draw on the screen at once. Default 100.
+.TP 8
+.B \-speed \fIinteger\fP
+A measure of the speed with which the observer and the rocks pass each other,
+from 1 to 100. Default 100, meaning ``very fast.'' If you're on a slow
+display connection (the animation looks jerky) then try making this number
+smaller, and/or decreasing the number of rocks.
+.TP 8
+.B \-delay \fImicroseconds\fP
+Number of microseconds to delay between each frame. Default 50000, meaning
+about 1/20th second. Compare and contrast with \fI\-speed\fP, above.
+.TP 8
+.B \-norotate
+Don't rotate the observer; just fly through the field on the level.
+.TP 8
+.B \-nomove
+Don't turn the observer; just fly straight ahead through the field.
+.TP 8
+.B \-3d
+Do red/blue 3d separations: if you look at the screen with 3d glasses,
+the rocks will be \fIjumping\fP right \fIout\fP at you. Oooooh, scaaary!
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.
+.SH SEE ALSO
+.BR X (1),
+.BR xscreensaver (1)
+.SH BUGS
+There should be an option to display doppler shift (a gravity rainbow.)
+
+Speed of rotation should be settable.
+
+Default speed of rotation should be relative to forward velocity.

+.SH SYNOPSIS
+.B xscreensaver-command
+[\-help] [\-demo] [\-activate] [\-deactivate] [\-lock] [\-cycle] [\-next] [\-prev] [\-exit] [\-restart] [\-version] [\-time]
+.SH DESCRIPTION
+The \fIxscreensaver\-command\fP program controls a running \fIxscreensaver\fP
+process by sending it client-messages.
+.SH OPTIONS
+.I xscreensaver-command
+accepts the following options:
+.TP 8
+.B \-help
+Prints a brief summary of command-line options.
+.TP 8
+.B \-demo
+Cause the screensaver to enter its interactive demo mode, in which one
+can experiment with the various graphics hacks available. See
+.BR xscreensaver (1)
+for details.
+.TP 8
+.B \-activate
+Tell the screensaver to turn on immediately (that is, pretend that the
+user been idle for long enough.) It will turn off as soon as there is
+any user activity, as usual.
+
+It is useful to run this from a menu; you may wish to run it as
+.EX
+sleep 5 ; xscreensaver-command -activate
+.EE
+to be sure that you have time to remove your hand from the mouse before
+the screensaver comes on.
+.TP 8
+.B \-deactivate
+Tell the screensaver to turn off, as if there had been user activity.
+If locking is enabled, then the screensaver will prompt for a password
+as usual.
+.TP 8
+.B \-lock
+Like \fI\-activate\fP, but a password will be required before the screensaver
+turns off, even if the screensaver's \fIlock\fP resource is false. The
+display will be locked immediately even if the screensaver's \fIlockTimeout\fP
+resource is non-zero.
+.TP 8
+.B \-cycle
+Tell the screensaver to change which graphics hack it is running, just
+as if the ``cycle'' timer had expired. A new hack will be chosen randomly.
+.TP 8
+.B \-next
+This is like either \fI\-activate\fP or \fI\-cycle\fP, depending on which is
+more appropriate, except that the screenhack that will be run is the next
+one in the list of programs, instead of a randomly-chosen one. Repeatedly
+executing this will cycle through each hack in turn (though using
+the \fI\-demo\fP option is probably an easier way to accomplish that.)
+.TP 8
+.B \-prev
+This is like \fI\-next\fP, but cycles in the other direction.
+.TP 8
+.B \-exit
+Causes the screensaver process to exit gracefully. This is a safer and
+easier way to kill the screensaver than by using \fIkill\fP.
+
+.B Warning:
+never use \fIkill -9\fP with \fIxscreensaver\fP while the screensaver is
+active. If you are using a virtual root window manager, that can leave
+things in an inconsistent state, and you may need to restart your window
+manager to repair the damage.
+.TP 8
+.B \-restart
+Causes the screensaver process to exit and then restart with the same command
+line arguments. This is a good way of causing the screensaver to re-read the
+resource database.
+
+If the screensaver is run from \fIxdm(1)\fP (that is, it is already running
+before you log in) then you may want to issue the ``restart'' command from
+one of your startup scripts, so that the screensaver gets your resource
+settings instead of the default ones.
+.TP 8
+.B \-version
+Print (on stdout) the version number of the xscreensaver program that is
+running on $DISPLAY. (To see the version number of \fIxscreensaver-command\fP
+itself, use the \fI\-help\fP option.)
+.TP 8
+.B \-time
+This option prints on stdout the time at which the screensaver last activated
+(blanked the screen) or deactivated (restored the screen.) Note that the
+activation-time is not the last time at which the user was active, but is
+some time later (it is the time at which either: xscreensaver decided that
+the user has been idle long enough; or, the user explicitly activated the
+screensaver or locker.)
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the host and display number of the screen whose saver is
+to be manipulated.
+.TP 8
+.B PATH
+to find the executable to restart (for the \fI\-restart\fP command).
+Note that this variable is consulted in the environment of
+the \fIxscreensaver\fP process, not the \fIxscreensaver-command\fP process.
+.SH "SEE ALSO"
+.BR X (1),
+.BR xscreensaver (1)
+.SH BUGS
+Some diagnostics are reported on the stderr of the \fIxscreensaver\fP
+process, not this process, so the caller of \fIxscreensaver-command\fP
+may not see the error messages.

+.SH NAME
+xscreensaver - graphics hack and screen locker, launched when the user is idle
+.SH SYNOPSIS
+.B xscreensaver
+[\-display \fIhost:display.screen\fP] [\-timeout \fIint\fP] [\-cycle \fIint\fP] [\-nice \fIint\fP] [\-lock] [\-no\-lock] [\-lock\-timeout \fIint\fP] [\-demo] [\-visual \fIvisual\fP] [\-install] [\-no\-install] [\-verbose] [\-silent] [\-xidle\-extension] [\-no\-xidle\-extension] [\-sgi\-extension] [\-no\-sgi\-extension] [\-mit\-extension] [\-no\-mit\-extension] [\-xrm \fIresources\fP]
+.SH DESCRIPTION
+The \fIxscreensaver\fP program waits until the keyboard and mouse have been
+idle for a period, and then runs a graphics demo chosen at random. It
+turns off as soon as there is any mouse or keyboard activity.
+
+This program can lock your terminal in order to prevent others from using it,
+though its default mode of operation is merely to display pretty pictures on
+your screen when it is not in use.
+
+The benefit that this program has over the combination of the
+.BR xlock (1)
+and
+.BR xautolock (1)
+programs is the ease with which new graphics hacks can be installed. You
+don't need to recompile (or even re-run) this program to add a new display
+mode.
+.SH OPTIONS
+.I xscreensaver
+accepts the following command line options:
+.TP 8
+.B \-timeout \fIminutes\fP
+The screensaver will activate after the keyboard and mouse have been idle
+for this many minutes. Default 10.
+.TP 8
+.B \-cycle \fIminutes\fP
+After the screensaver has been running for this many minutes, the currently
+running graphics hack sub-process will be killed (with \fBSIGTERM\fP), and a
+new one started. If this is 0, then the graphics hack will not be changed:
+only one demo will run until the screensaver is deactivated by user activity.
+Default 10.
+.TP 8
+.B \-nice \fIinteger\fP
+The sub-processes created by \fIxscreensaver\fP will be ``niced'' to this
+level, so that they are given lower priority than other processes on the
+system, and don't increase the load unnecessarily. The default is 20.
+
+(Higher numbers mean lower priority; see
+.BR nice (1)
+for details.)
+.TP 8
+.B \-lock
+Enable locking: before the screensaver will turn off, it requires you to
+type the password of the person who launched the screensaver, or the root
+password. (Note: this doesn't work if the screensaver is launched
+by
+.BR xdm (1)
+because it can't know the user-id of the logged-in user.)
+.TP 8
+.B \-no\-lock
+Disable locking. This is the default.
+.TP 8
+.B \-lock\-timeout \fIminutes\fP
+This is how long after the screensaver activates that locking is enabled.
+For example, if this is 5, and \fI\-timeout\fP is 10, then after 10 minutes,
+the screen would blank. If there was user activity at 12 minutes, no password
+would be required. But, if there was user activity at 15 minutes or later
+(\fI\-lock\-timeout\fP minutes after activation) then a password would be
+required. The default is 0, meaning that if locking is enabled, then
+a password will be required as soon as the screensaver activates.
+.TP 8
+.B \-demo
+Enter the interactive demo mode immediately after startup. Normally
+demo mode is invoked via the
+.BR xscreensaver\-command (1)
+program, but this is a shortcut for new users. See below for a description
+of how demo-mode works.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which X visual to use by default. Legal values are:
+.RS 8
+.TP 8
+.B default
+Use the screen's default visual (the visual of the root window.)
+This is the default.
+.TP 8
+.B best
+Use the visual which supports the most colors. Note, however, that the
+visual with the most colors might be a TrueColor visual, which does not
+support colormap animation.
+.TP 8
+.B mono
+Use a monochrome visual, if there is one.
+.TP 8
+.B gray
+Use a grayscale or staticgray visual, if there is one and it has more than
+one plane (that is, it's not monochrome.)
+.TP 8
+.B color
+Use the best of the color visuals, if there are any.
+.TP 8
+.I class
+where \fIclass\fP is one
+
+of \fBStaticGray\fP, \fBStaticColor\fP, \fBTrueColor\fP, \fBGrayScale\fP, \fBPseudoColor\fP,
+or \fBDirectColor\fP. Selects the deepest visual of
+the given class.
+.TP 8
+.I number
+where \fInumber\fP (decimal or hex) is interpreted as a visual id number,
+as reported by the
+.BR xdpyinfo (1)
+program; in this way you can have finer control over exactly which visual
+gets used, for example, to select a shallower one than would otherwise
+have been chosen.
+.RE
+.RS 8
+.PP
+Note that this option specifies only the \fIdefault\fP visual that will
+be used: the visual used may be overridden on a program-by-program basis.
+See the description of the \fBprograms\fP resource, below.
+.RE
+.TP 8
+.B \-install
+When using a non-default visual, install a private colormap while the
+screensaver is active, so that the graphics hacks can get as many colors as
+possible. This is the default. (This only applies when the screen's
+default visual is being used, since non-default visuals get their own
+colormaps automatically.)
+.TP 8
+.B \-no\-install
+Use the default colormap.
+.TP 8
+.B \-verbose
+Print diagnostics.
+.TP 8
+.B \-silent
+
+.TP 8
+.B \-xidle\-extension
+Use the \fBXIDLE\fP server extension to decide whether the user is idle.
+This is the default if \fIxscreensaver\fP has been compiled with support
+for this extension. On X11R4 or X11R5 systems, the XIdle method is faster
+and more reliable than what will be done otherwise, so use it if you can.
+.TP 8
+.B \-no\-xidle\-extension
+Don't use the \fBXIDLE\fP server extension.
+.TP 8
+.B \-sgi\-extension
+Use the SGI \fBSCREEN_SAVER\fP server extension to decide whether the user
+is idle. This is the default if \fIxscreensaver\fP has been compiled with
+support for this extension (which is the default on SGI systems.). If it
+is available, the \fBSCREEN_SAVER\fP method is faster and more reliable than
+what will be done otherwise, so use it if you can.
+.TP 8
+.B \-no\-sgi\-extension
+Don't use the SGI \fBSCREEN_SAVER\fP server extension.
+.TP 8
+.B \-mit\-extension
+Use the \fBMIT\-SCREEN\-SAVER\fP server extension to decide whether the user
+is idle. This is the default if \fIxscreensaver\fP has been compiled with
+support for this extension. However, this extension is flaky, so it's use
+is not really recommended. (It also makes the \fIfade\fP option not work
+properly.)
+.TP 8
+.B \-no\-mit\-extension
+Don't use the \fBMIT\-SCREEN\-SAVER\fP server extension.
+.SH X RESOURCES
+\fIxscreensaver\fP understands the following resources:
+.PP
+.TP 8
+.B timeout \fR(class \fBTime\fP)
+Same as the \fI\-timeout\fP command-line option. Default 10 minutes.
+.TP 8
+.B cycle \fR(class \fBTime\fP)
+Same as the \fI\-cycle\fP command-line option. Default 10 minutes.
+.TP 8
+.B nice \fR(class \fBNice\fP)
+Same as the \fI\-nice\fP command-line option. Default 10.
+.TP 8
+.B lock \fR(class \fBBoolean\fP)
+Same as the \fI\-lock\fP command-line option.
+.TP 8
+.B lockTimeout \fR(class \fBTime\fP)
+Same as the \fI\-lock\-timeout\fP command-line option.
+.TP 8
+.B passwdTimeout \fR(class \fBTime\fP)
+If the screen is locked, then this is how many seconds the password dialog box
+should be left on the screen before giving up (default 30.) This should not
+be too large: the X server is grabbed for the duration that the password
+dialog box is up (for security purposes) and leaving the server grabbed for
+too long can cause problems.
+.TP 8
+.B verbose \fR(class \fBBoolean\fP)
+Same as the \fI\-verbose\fP command-line option.
+.TP 8
+.B xidle \fR(class \fBBoolean\fP)
+Same as the \fI\-xidle\fP command-line option.
+.TP 8
+.B fade \fR(class \fBBoolean\fP)
+If this is true, then when the screensaver activates, the current contents
+of the screen will fade to black instead of simply winking out. This only
+works on displays with writable colormaps, that is, if the screen's default
+visual is a PseudoColor visual. Default true. A fade will also be done when
+switching graphics hacks (when the \fIcycle\fP timer expires.)
+.TP 8
+.B unfade \fR(class \fBBoolean\fP)
+If this is true, then when the screensaver deactivates, the original contents
+of the screen will fade in from black instead of appearing immediately. This
+only works on displays with writable colormaps, and if \fIfade\fP is true
+as well. Default false.
+.TP 8
+.B fadeSeconds \fR(class \fBTime\fP)
+If \fIfade\fP is true, this is how long the fade will be in
+seconds (default 3.)
+.TP 8
+.B fadeTicks \fR(class \fBInteger\fP)
+If \fIfade\fP is true, this is how many times a second the colormap will
+be changed to effect a fade. Higher numbers yield smoother fades, but
+may make the fades take longer than the specified \fIfadeSeconds\fP if
+your server isn't fast enough to keep up. Default 20.
+.TP 8
+.B visualID \fR(class \fBVisualID\fP)
+Same as the \fI\-visual\fP command-line option. Default \fBdefault\fP.
+.TP 8
+.B installColormap \fR(class \fBBoolean\fP)
+Same as the \fI\-install\fP command-line option. Default true.
+.TP 8
+.B captureStderr \fR(class \fBBoolean\fP)
+Whether \fIxscreensaver\fP should redirect its standard-error stream to the
+window itself. Since its nature is to take over the screen, you would not
+normally see error messages generated by the screensaver or the programs it
+runs; this resource will cause the output of all relevant programs to be
+drawn on the screensaver window itself instead of written to the controlling
+terminal of the screensaver driver process. Default true.
+.TP 8
+.B captureStdout \fR(class \fBBoolean\fP)
+Like \fBcaptureStderr\fP but for the standard-output stream. Default true.
+.TP 8
+.B font \fR(class \fBFont\fP)
+The font used for the stdout/stderr text, if \fBcaptureStdout\fP or
+\fBcaptureStderr\fP are true. Default \fB*\-medium\-r\-*\-140\-*\-m\-*\fP
+(a 14 point fixed-width font.)
+.TP 8
+.B textForeground \fR(class \fBForeground\fP)
+The foreground color used for the stdout/stderr text, if \fBcaptureStdout\fP
+or \fBcaptureStderr\fP are true. Default: Yellow.
+.TP 8
+.B textBackground \fR(class \fBBackground\fP)
+The background color used for the stdout/stderr text, if \fBcaptureStdout\fP
+or \fBcaptureStderr\fP are true. Default: Black.
+.TP 8
+.B programs \fR(class \fBPrograms\fP)
+The graphics hacks which \fIxscreensaver\fP runs when the user is idle.
+The value of this resource is a string, one \fIsh\fP-syntax command per line.
+Each line must contain exactly one command -- no semicolons, no ampersands.
+
+When the screensaver starts up, one of these is selected at random, and
+run. After the \fIcycle\fP period expires, it is killed, and another
+is selected and run.
+
+If the value of this resource is empty, then no programs will be run; the
+screen will simply be made black.
+
+If the display has multiple screens, then a different program will be run
+for each screen.
+
+Note that you must escape the newlines; here is an example of how you
+might set this in your \fI.Xdefaults\fP file:
+
+.EX
+xscreensaver.programs: \\
+ qix -root \\n\\
+ ico -r -faces -sleep 1 -obj ico \\n\\
+ xdaliclock -builtin2 -root \\n\\
+ xv -root -rmode 5 image.gif -quit \\n
+.EE
+.RS 8
+To use a program as a screensaver, two things are required: that that
+program draw on the root window (or be able to be configured to draw on
+the root window); and that that program understand ``virtual root''
+windows, as used by virtual window managers such as \fItvtwm\fP. (Generally,
+this is accomplished by just including the \fI"vroot.h"\fP header file in
+the program's source.)
+
+If there are some programs that you want to run only when using a color
+display, and others that you want to run only when using a monochrome
+display, you can specify that like this:
+
+.EX
+ mono: mono-program -root \\n\\
+ color: color-program -root \\n\\
+.EE
+.RE
+.RS 8
+More generally, you can specify the kind of visual that should be used for
+the window on which the program will be drawing. For example, if one
+program works best if it has a colormap, but another works best if it has
+a 24-bit visual, both can be accomidated:
+
+.EX
+ PseudoColor: cmap-program -root \\n\\
+ TrueColor: 24bit-program -root \\n\\
+.EE
+.RE
+.RS 8
+(This sort of thing used to be accomplished with the \fIcolorPrograms\fP
+and \fImonoPrograms\fP resources, but those resources have now been removed;
+a warning will be issued if they are used.)
+
+If you specify a particular visual for a program, and that visual does not
+exist on the screen, then that program will not be chosen to run. This
+means that on displays with multiple screens of different depths, you can
+arrange for appropriate hacks to be run on each. For example, if one screen
+is color and the other is monochrome, hacks that look good in mono can be
+run on one, and hacks that only look good in color will show up on the other.
+.RE
+.PP
+.PP
+Normally you won't need to change the following resources:
+.TP 8
+.B bourneShell \fR(class \fBBourneShell\fP)
+The pathname of the shell that \fIxscreensaver\fP uses to start subprocesses.
+This must be whatever your local variant of \fB/bin/sh\fP is -- in particular,
+it must not be \fBcsh\fP.
+.TP 8
+.B windowCreationTimeout \fR(class \fBTime\fP)
+When server extensions are not in use, this controls the delay between when
+windows are created and when \fIxscreensaver\fP selects events on them.
+Default 30 seconds.
+.TP 8
+.B pointerPollTime \fR(class \fBTime\fP)
+When server extensions are not in use, this controls how
+frequently \fIxscreensaver\fP checks to see if the mouse position or buttons
+have changed. Default 5 seconds.
+.TP 8
+.B initialDelay \fR(class \fBTime\fP)
+When server extensions are not in use, \fIxscreensaver\fP will wait this many
+seconds before selecting events on existing windows, under the assumption that
+\fIxscreensaver\fP is started during your login procedure, and the window
+state may be in flux. Default 30 seconds.
+.TP 8
+.B overlayStderr \fR(class \fBBoolean\fP)
+If \fBcaptureStderr\fP or \fBcaptureStdout\fP are True, and your server
+supports ``overlay'' visuals, then the text will be written into one of
+the higher layers instead of into the same layer as the running screenhack.
+Set this to False to disable that (though you shouldn't need to.)
+.SH "HOW IT WORKS"
+When it is time to activate the screensaver, a full-screen black window is
+created on each screen of the display. The window or windows is given the
+appropriate properties so that, to any subsequently-created programs, it
+will appear to be a ``virtual root'' window. Because of this, any program
+which draws on the root window (and which understands virtual roots) can be
+used as a screensaver.
+
+When the user becomes active again, the screensaver windows are unmapped and
+the running subprocesses are killed by sending them \fBSIGTERM\fP. This is
+also how the subprocesses are killed when the screensaver decides that it's
+time to run a different demo: the old one is killed and a new one is launched.
+
+Before launching a subprocess, \fIxscreensaver\fP stores an appropriate value
+for \fB$DISPLAY\fP in the environment that the child will recieve. (This is
+so that if you start \fIxscreensaver\fP with a \fI-display\fP argument, the
+programs which \fIxscreensaver\fP launches will draw on the same display;
+and so that the child will end up drawing on the appropriate screen of a
+multi-headed display.)
+
+When the screensaver turns off, or is killed, care is taken to restore
+the ``real'' virtual root window if there is one. Because of this, it is
+important that you not kill the screensaver process with \fIkill -9\fP if
+you are running a virtual-root window manager. If you kill it with \-9,
+you may need to restart your window manager to repair the damage. This
+isn't an issue if you aren't running a virtual-root window manager.
+
+For all the gory details, see the commentary at the top of xscreensaver.c.
+
+You can control a running screensaver process by using the
+.BR xscreensaver\-command (1)
+program (which see.)
+.SH USING XDM(1)
+You can run \fIxscreensaver\fP from your xdm session, so that the
+screensaver will run even when nobody is logged in on the console.
+Simply add \fB"xscreensaver &"\fP to your \fI/usr/lib/X11/xdm/Xsetup\fP
+file. Because \fIxdm\fP grabs the keyboard, keypresses will not make
+the screensaver deactivate, but any mouse activity will.
+
+(If your system does not seem to be executing the \fIXsetup\fP file, you
+may need to configure it to do so -- the traditional way to do this is
+to make that file the value of the \fIDisplayManager*setup\fP resource
+in the \fIxdm-config\fP file. See the man page for
+.BR xdm (1)
+for more details.)
+
+Users may want to add \fB"xscreensaver-command -restart"\fP to their
+startup scripts, so that the screensaver will be reinitialized with
+their private resource settings when they log in.
+
+It is safe to run this program as root (as \fIxdm\fP is likely to do.) If
+run as root, \fIxscreensaver\fP changes its effective user and group ids to
+something safe (like \fI"nobody"\fP) before connecting to the X server
+or launching user-specified programs.
+
+Locking doesn't work if the screensaver is launched by \fIxdm\fP. To get
+around this, you can run the screensaver from \fIxdm\fP without locking,
+and kill and restart it from your personal X startup script to enable
+locking; for example:
+
+.EX
+ xscreensaver-command -exit ; xscreensaver
+.EE
+.SH DEMO MODE
+If \fIxscreensaver\fP receives the \fBDEMO\fP ClientMessage, which is done
+by running the \fBxscreensaver\-command\fP program with the \fB\-demo\fP
+option, the screensaver will black the screen and pop up a dialog box from
+which you can examine and experiment with the client programs.
+
+The dialog box contains a scrolling list, a text field, and a number of
+buttons.
+
+Double-clicking on one of the programs in the list will run it. Clicking
+the mouse again will bring the dialog box back.
+
+Single-clicking in the list will place the indicated program and its args
+in the text field to be edited. Edit the arguments and hit return to run
+the program with the parameters you have specified. (Note that these are
+one-time changes and won't be remembered; to make the changes permanent,
+you need to edit your X resource file.)
+
+The buttons are:
+.TP 8
+.B Run Next
+Clicking this button will run the next program in the list after the
+currently-selected one, and will scroll around to the top when it reaches
+the bottom.
+.TP 8
+.B Run Previous
+Opposite of Run Next; at the top, it scrolls around to the bottom.
+.TP 8
+.B Edit Parameters
+This pops up a second dialog box, in which you have the option to
+interactively change most of the screensaver's operational parameters,
+such as its timeouts, and whether it should lock the screen. Changing
+these parameters here will affect only the running \fIxscreensaver\fP
+process; to make the changes permanent, you need to edit your X resource
+file.
+.TP 8
+.B Exit Demo Mode
+Returns to normal screensaver operation.
+.TP 8
+.B Reinitialize
+This causes the X resource database to be re-read, to pick up any changes
+you might have made. This works by causing the screensaver process to exit
+and then restart itself with the same command-line arguments. This is just
+like the \fI\-restart\fP argument to
+.BR xscreensaver\-command (1)
+except that when executed from this button, the screensaver will
+automatically return to demo mode after restarting.
+.SH BUGS
+(This is not a bug, but) note that as of release 1.32, the \fBcolorPrograms\fP
+and \fBmonoPrograms\fP resources are no longer used: they have been
+supplanted by the extended syntax of the \fBprograms\fP resource (see above.)
+.TP 8
+Extensions
+If you are not making use of one of the server extensions (\fBXIDLE\fP,
+\fBSCREEN_SAVER\fP, or \fBMIT-SCREEN-SAVER\fP), then it is possible, in rare
+situations, for \fIxscreensaver\fP to interfere with event propagation and make
+another X program malfunction. For this to occur, that other application
+would need to \fInot\fP select \fBKeyPress\fP events on its non-leaf windows
+within the first 30 seconds of their existence, but then select for them later.
+In this case, that client \fImight\fP fail to receive those events.
+This isn't very likely, since programs generally select a constant set
+of events immediately after creating their windows and then don't change
+them, but this is the reason that it's a good idea to install and use one
+of the server extensions instead, to work around this shortcoming in the
+X protocol.
+.TP 8
+Machine Load
+Although this program ``nices'' the subprocesses that it starts,
+graphics-intensive subprograms can still overload the machine by causing
+the X server process itself (which is not ``niced'') to suck a lot of
+cycles. Care should be taken to slow down programs intended for use as
+screensavers by inserting strategic calls to
+.BR sleep (3)
+or
+.BR usleep (3)
+(or making liberal use of any \fI\-delay\fP options which the programs
+may provide.)
+
+Also, an active screensaver will cause your X server to be pretty much
+permanently swapped in; but the same is true of any program that draws
+periodically, like
+.BR xclock (1)
+or
+.BR xload (1).
+.TP 8
+Latency and Responsiveness
+If the subprocess is drawing too quickly and the connection to the X
+server is a slow one (such as an X terminal running over a phone line) then
+the screensaver might not turn off right away when the user becomes active
+again (the
+.BR ico (1)
+demo has this problem if being run in full-speed mode). This can be
+alleviated by inserting strategic calls to
+.BR XSync (3)
+in code intended for use as a screensaver. This prevents too much graphics
+activity from being buffered up.
+.TP 8
+Locking and XDM
+Locking doesn't work if the screensaver is launched by \fIxdm\fP.
+The reason for this is that when it is launched by \fIxdm\fP, the
+screensaver process is owned by some standard user id (such as \fIroot\fP
+or \fIdaemon\fP) instead of the user who is logged in on the console:
+because the screensaver was started \fIbefore\fP anyone was logged in.
+In order for the screensaver to prompt for the password of the person
+who had logged in from \fIxdm\fP, it would need to know who that user was,
+and there is no reliable and safe way to figure that out. (And even if
+there was, there would be some other security issues here as well.)
+
+So if you want to use it as a locker, you must start it with your user id.
+If it has already been started by \fIxdm\fP, you can kill it with
+\fBxscreensaver-command -exit\fP, and then start it again as you.
+.TP 8
+Passwords
+If you get an error message like ``couldn't get password of \fIuser\fP''
+then this probably means that you're on a system in which the
+.BR getpwent (3)
+library routine can only be effectively used by root. If this is the case,
+then \fIxscreensaver\fP must be installed as setuid to root. Care has
+been taken to make this a safe thing to do.
+
+It also may mean that your system uses shadow passwords instead of the
+standard \fIgetpwent\fP interface; in that case, you may need to change
+some options in \fIconfig.h\fP and recompile.
+.TP 8
+TWM and Colormaps
+The \fBinstallColormap\fP option doesn't work very well with the
+.BR twm (1)
+window manager and its descendants.
+
+There is a race condition between the screensaver and this window manager,
+which can result in the screensaver's colormap not getting installed
+properly, meaning the graphics hacks will appear in essentially random
+colors. (If the screen goes white instead of black, this is probably why.)
+
+The
+.BR mwm (1)
+and
+.BR olwm (1)
+window managers don't seem to have this problem. The race condition exists
+because X apparently does not provide a way for an OverrideRedirect window to
+have its own colormap, short of grabbing the server (which is neither a good
+idea, nor really possible with the current design.) What happens is that, as
+soon as the screensaver installs its colormap, \fBtwm\fP responds to
+the \fBColormapNotify\fP event that is generated by re-instaling the default
+colormap. Apparently, \fBtwm\fP doesn't \fIalways\fP do this; it seems to do
+it regularly if the screensaver is activated from a menu item, but seems to
+not do it if the screensaver comes on of its own volition, or is activated
+from another console. Any thoughts on this problem are welcome...
+.TP 8
+XView Clients
+Apparently there are some problems with XView programs getting confused
+and thinking that the screensaver window is the real root window even when
+the screensaver is not active: ClientMessages intended for the window manager
+are sent to the screensaver window instead. This could be solved by making
+xscreensaver forward all unrecognised ClientMessages to the real root window,
+but there may be other problems as well. If anyone has any insight on the
+cause of this problem, please let me know.
+.TP 8
+MIT Extension and Fading
+When using the \fBMIT-SCREEN-SAVER\fP extension in conjunction with
+the \fBfade\fP option, you may notice an unattractive flicker just before
+the fade begins. This is because the server maps a black window just before
+it tells the \fIxscreensaver\fP process to activate. The \fIxscreensaver\fP
+process immediately unmaps that window, but this results in a flicker. I
+haven't figured a way to get around this; it seems to be a fundamental
+property of the (mis-) design of this server extension.
+.TP 8
+LessTif (Motif Clone)
+Rumor has it that demo mode is buggy if XScreenSaver was compiled with the
+GNU LessTif reimplementation of Motif. Since it works fine with OSF Motif
+on a variety of systems, I assume these problems are due to bugs in LessTif.
+Again, any insight would be appreciated.
+.TP 8
+Red Hot Lava
+There need to be a lot more graphics hacks. In particular, there should be
+a simulation of a Lavalite (tm).
