It is trivially easy to add new display modes to xscreensaver: any program
which can be invoked in such a way that it draws on the root window of the
-screen can be used as a screensaver. You just change a resource setting --
+screen can be used as a screensaver. You just change a config file --
there's no need to recompile or reinstall anything.
============
============
+Changes since 3.11: * Made it so that you can't scroll the screen while the
+ lock dialog is up (with XFree86 virtual viewports.)
+ * Fixed a bug in `flag' that caused bob's chin to get cut
+ off after a few iterations.
+Changes since 3.10: * Made `xjack' be black-on-white-ish, so that it looks
+ less like a computer screen and more like the
+ typewritten paper it's supposed to be.
+ * New version of `pulsar'.
+ * Fixed Solaris compilation problem in `phosphor'.
+ * Made xscreensaver notice XFree86's virtual root window
+ hack, so that if the X server's root window is larger
+ than the monitor's displayable resolution, the screen
+ saver will limit itself to the area that actually
+ appears on the screen.
+ * Made the xscreensaver daemon do a better job of
+ picking the visual class that should be used for GL
+ programs. Less user intervention should be needed
+ now: you can use the logical visual name `GL' instead
+ of having to figure out by hand which one to use.
+ * Oops, the visual was defaulting to "best" instead of
+ "default", because the .xscreensaver file was not being
+ loaded quite early enough.
+ * Made configure figure out how to build icmp ping
+ support into the `sonar' hack automatically.
+ * Made warnings about not being able to read shadow
+ passwords not be printed if compiled with PAM support.
+ * Improved PAM startup diagnostics.
+ * Worked around the Solaris PAM bug that was causing
+ crashes there, so now PAM is turned on by default.
+ * Made configure detect the number of arguments that
+ pam_strerror() takes, since on Linux, this apparently
+ changed between 2.0 and 2.2, sigh.
+ * Made the /proc/interrupts kludge look for "PS/2 Mouse"
+ as well as "keyboard".
+ * Made xscreensaver notice when there has been a sudden
+ large jump in wall-clock time, and if so, lock right
+ away, instead of waiting for "lockTimeout" to expire
+ first. (Laptops need this for safer recovery from
+ ``hibernation.'')
+ * Added `-throttle' option to `xscreensaver-command'.
Changes since 3.09: * Added `phosphor', `xmatrix', and `pulsar' hacks.
* Fixed a bug in the color allocator that sometimes
caused `starfish' to fall back to monochrome.

! a screen saver and locker for the X window system
! by Jamie Zawinski
!
-! version 3.10
-! 27-Apr-99
+! version 3.12
+! 10-May-99
!
! See "man xscreensaver" for more info. The latest version is always
! available at http://www.jwz.org/xscreensaver/
*fadeTicks: 20
*splash: True
*splashDuration: 5
+*visualID: default
*captureStderr: True
*overlayTextForeground: #FFFF00
! colormaps, but others prefer 24-bit windows, that also can be arranged
! (in this case, by using "PseudoColor:" versus "TrueColor:".)
!
+! Some of the screenhacks are written using OpenGL. OpenGL programs are
+! a bit different than normal X programs, in that they prefer visuals that
+! are *half* as deep as the screen. You can tell xscreensaver to select a
+! good visual for a GL program by using the magic visual name "GL".
+!
! 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.)
!
-! Be sure to check out Demo Mode: run the command `xscreensaver-command -demo'
-! and it will cause the running XScreenSaver program to pop up a dialog box
-! that lets you try out the following programs interactively. See the man
-! pages for details.
+! Be sure to check out Demo Mode: run the `xscreensaver-demo' program to
+! edit the current list of programs interactively, try out the various modes,
+! and change other parameters. See the man page for details.

-! A few of the hacks require OpenGL, and will only be built if you have it.
-! If your vendor doesn't provide real OpenGL, you might want to consider
-! building MesaGL, which is a free implementation -- GL is way cool.
-!
-! Note that those hacks (gears, superquadratics, morph3d, cage, moebius,
-! stairs, pipes, sproingies, and rubik) tend to work best on a visual *half*
-! as deep as the depth of the screen, since that way, they can do
-! double-buffering -- try it and see, but you will probably find that you
-! should specify the deepest visual that is half as deep as the screen.
-!
-! For example, on a screen that supports both 24-bit TrueColor and 12-bit
-! PseudoColor, the 12-bit visual will probably work best (this is true of
-! base-model SGI Indys: the 0x29 visual is the one you want.) Oddly, on SGI
-! O2s, (machines that have serious hardware support for GL) the 12-bit
-! PseudoColor visual looks awful (you get a black and white, flickery image.)
-! On these machines, the visual you want turns out to be 0x31 -- this is but
-! one of the eight 15-bit TrueColor visuals (yes, 8, and yes, 15) that O2s
-! provide. This is the only visual that works properly -- as far as xdpyinfo
-! is concerned, all of the 15-bit TrueColor visuals are identical, but some
-! flicker like mad, and some have deeply weird artifacts (hidden surfaces
-! show through!) I suppose these other visuals must be tied to some arcane
-! hardware feature... Your mileage, therefore, may vary dramatically.
-!
! Some other programs that you might want to track down (these work as
! XScreenSaver helpers, but are not distributed with it):

+
+ He also confirms that this behavior is server-dependent, so the
+ actual scroll position cannot be reliably determined by the client.
+ So... that means the only solution is to provide a ``sandbox''
+ around the blackout window -- we make the window be up to N pixels
+ larger than the viewport on both the left and right sides. That
+ means some part of the outer edges of each hack might not be
+ visible, but screw it.
+
+ I'm going to guess that 16 pixels is enough, and that the Y dimension
+ doesn't have this problem.
+
+ The drawback of doing this, of course, is that some of the screenhacks

.SH NAME
xscreensaver - graphics hack and screen locker, launched when the user is idle
.SH SYNOPSIS
.B color
Use the best of the color visuals, if there are any.
.TP 8
+.B GL
+Use the visual that is best for OpenGL programs. (OpenGL programs have
+somewhat different requirements than other X programs.)
+.TP 8
.I class
where \fIclass\fP is one of \fBStaticGray\fP, \fBStaticColor\fP,
\fBTrueColor\fP, \fBGrayScale\fP, \fBPseudoColor\fP, or \fBDirectColor\fP.
after an hour or two even if you've told it not to. This is fixed by SGI
patches 2447 and 2537.
.TP 8
-.B OpenGL Programs and Visuals
-Some of the graphics demos included with xscreensaver make use of the
-OpenGL (or MesaGL) 3D library, if it is available. It is possible (even
-likely) that \fIxscreensaver\fP's notion of the ``\fIbest\fP'' visual is
-not quite right for these GL programs.
-
-The odd thing about GL programs is that, unlike normal X11 programs, they
-tend to work best on a visual \fIhalf\fP as deep as the depth of the screen,
-since that way, they can do double-buffering. Try it and see, but you will
-probably find that, for these particular programs, you should specify the
-deepest visual that is half as deep as the screen. (See the discussion
-of the \fBprograms\fP resource in the \fIConfiguration\fP section, above.)
-
-For example, on a screen that supports both 24-bit TrueColor and 12-bit
-PseudoColor visuals, the 12-bit visual will probably work best (this is true
-of base-model SGI Indys: the 0x29 visual is the one you want.)
-
-Oddly, on SGI O2s (machines that have serious hardware support for GL), the
-12-bit PseudoColor visual looks awful (you get a black and white, flickery
-image.) On these machines, the visual you want turns out to be 0x31.
-However, 0x31 is but \fIone\fP of the \fIeight\fP 15-bit TrueColor visuals
-(yes, 8, and yes, 15) that the O2 X server provides. This is the only visual
-that works properly: as far as
-.BR xdpyinfo (1)
-is concerned, all of the 15-bit TrueColor visuals are identical, but some
-flicker like mad, and some have deeply weird artifacts (such as hidden
-surfaces that show through, as if depth worked backwards!)
-
-I suppose these other visuals must be tied to some arcane hardware feature...
-If anyone would care to explain it to me, that would be great.
-
-Your mileage, therefore, may vary dramatically.

* Revision History:
* 4-Apr-1999: dek@cgl.ucsf.edu Created module "pulsar"
+ * 27-Apr-1999: dek@cgl.ucsf.edu Submitted module "pulsar"
+ * 4-May-1999: jwz@jwz.org Added module "pulsar"
+ * 4-May-1999: dek@cgl.ucsf.edu Submitted module "pulsar" updates
*
+ * Notes:
+ * The pulsar screensaver draws a number of rotating, pulsing rectangles
+ * on your screen. Depending on the options you choose, you can set a number
+ * of interesting OpenGL parameters, including alpha blending, depth testing, fog,
+ * lighting, texturing, mipmapping, bilinear filtering, and line antialiasing.
+ * Additionally, there is a "frames per second" meter which gives an estimate of
+ * the speed of your graphics card.
+ *
+ * Example command-line switches:
+ * Only draw a single quad, and don't fill it (boring but fast)
+ * pulsar -wire -quads 1 -fps
+ *
+ * Only try this with hardware graphics acceleration (PPro 200 w/ a Voodoo 2 runs great)
+ * pulsar -quads 10 -texture -mipmap -texture_quality -light -fog -fps

+/* This file contains code for picking the best visual for GL programs by
+ actually asking the GL library to figure it out for us. The code in
+ visual.c might do a good job of this on most systems, but not, in
+ particular, on SGIs.
+
+ Why? Because with the SGI O2 X server is weird.
+
+ GL programs tend to work best on a visual that is *half* as deep as the
+ depth of the screen, since that way, they can do double-buffering. So
+ generally, if the screen is 24 bits deep, but a 12-bit TrueColor visual
+ is available, then that's the visual you should use.
+
+ But on the server that runs on the O2 (a machine that has serious hardware
+ support for GL) the 12-bit PseudoColor visual looks awful (you get a black
+ and white, flickery image.) On these machines, the visual you want turns
+ out to be 0x31 -- this is but one of the eight 15-bit TrueColor visuals
+ (yes, 8, and yes, 15) that O2s provide. This is the only visual that works
+ properly -- as far as `xdpyinfo' is concerned, all of the 15-bit TrueColor
+ visuals are identical, but some flicker like mad, and some have deeply
+ weird artifacts (hidden surfaces show through!) I suppose these other
+ visuals must be tied to some arcane hardware feature...
+
+ So the bottom line is, there exists information about visuals which is
+ available to GL, but which is not available via Xlib calls. So the only
+ way to know which visual to use (other than impirically) is to actually
+ call GLX routines.
