XScreenSaver
- a screen saver and locker for the X window system
- by Jamie Zawinski
+ a collection of
+ free screen savers
+ for X11 and MacOS
- http://www.jwz.org/xscreensaver/
-
-To build on Unix:
-
- - ./configure
- - make
- - make install
-
-The `configure' shell script will attempt to figure out which options are
-appropriate for your system, and will create config.h and the various
-Makefiles for you. Run `configure --help' to see how to override these
-choices, or to specify things like the default installation directory.
-The file `INSTALL' gives a general overview of use of these sorts of
-configure scripts (those generated by the GNU autoconf system.)
-The most important hint is probably this:
-
- ./configure --with-motif=/opt/Motif --with-xpm=/usr/local
-
-To build on VMS, see README.VMS.
+ By Jamie Zawinski
+ and many others
-If you are upgrading, you might want to delete your ~/.xscreensaver file.
-If you don't, you might not see the new graphics modes. If you are upgrading
-from version 2.* to version 3.*, definitely do delete your .xscreensaver file.
-
-If you think you've found a bug, please let me know! No bug report is too
-small. But first, please read the enclosed `README.debugging' file to find
-out what kind of information would be most helpful to include in your bug
-report.
-
-Getting Started:
-
-You can try out xscreensaver like so:
-
- xscreensaver &
- xscreensaver-command -demo
+ http://www.jwz.org/xscreensaver/
-After a few seconds, the screen should go black, and a dialog box should
-appear in the upper right corner. This is "Demo Mode".
+===============================================================================
-Note: unlike `xlock', xscreensaver has a client-server model: the
-`xscreensaver' process is a daemon that runs in the background; it is
-controlled by the foreground `xscreensaver-command' program.
+This is the XScreenSaver source code distribution. It is strongly recommended
+that you install a binary release rather than trying to compile it yourself.
+Binaries are available for almost all platforms, including MacOS X. See the
+XScreenSaver web site for details.
-xscreensaver has an extensive manual -- please read it!
+To compile on a Unix system with X11:
- ============
+ ./configure
+ make
+ make install
-The xscreensaver daemon waits until the keyboard and mouse have been idle
-for a period, and then runs a graphics demo chosen at random. The demo is
-terminated as soon as there is any mouse or keyboard activity (or, in
-locking mode, when the proper password is typed.)
+To compile on MacOS X:
-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 --
-there's no need to recompile or reinstall anything.
+ Use the included XCode project. Requires XCode 4 and MacOS X 10.5
+ or newer.
- ============
+Interested in writing a new screen saver?
-Along with the xscreensaver daemon itself, this package also includes
-numerous graphics hacks for use as screensavers. There is nothing magic
-about these: they are just programs that draw on the root window.
+ See the README.hacking file.
-More than 80 such programs are included. For details, see the xscreensaver
-web page, or the enclosed manual pages. There are also some helpful hints
-on customization in the xscreensaver app-defaults file (normally installed
-in /usr/lib/X11/app-defaults/XScreenSaver.)
+===============================================================================
-The latest version of xscreensaver is always available on the web at
-http://www.jwz.org/xscreensaver/.

+ fallout from the recent PAM changes...)
+ * New hacks, `moebiusgears', `abstractile', and
+ `lockward'.

+ * Added MacOS 10.2 and 10.3 kernel panics to `bsod'.
+ * Fixed a Xinerama crash when changing the screen count.
+ * New blobbier `mirrorblob'.
+ * Minor updates to `lisa', `bsod', `ifs', `hypertorus',
+ `polytopes', `circuit', `endgame', `crackberg',
+ `flipflop', `flipscreen3d', `fliptext', and `carousel'.
+ * Enabled multi-threaded OpenGL on MacOS.
+Changes since 5.00: * Backed out recent locale-related changes, since they
+ broke far more things than they fixed.
+ * Fail gracefully with ridiculously small window sizes.
+ * `xflame' and `flag' ignore bitmap option on MacOS.
+ * `speedmine' prefs work on MacOS.
+ * Better explosions in `boxed'.
+ * More dynamic motion in `sproingies'.
+ * More options in `flipflop'.
+ * Minor updates to `topblock'.
+ * Various other minor fixes.
+Changes since 4.24: * Ported to MacOS X! (10.4.0 or newer)
+ * API change: instead of providing a single screenhack()
+ function that does not return, screen savers using the
+ screenhack.h framework must now provide "init" and
+ "draw one frame" functions instead. All bundled savers
+ have been updated; third-party patches will need work.
+ * All image-loading happens asynchronously.
+ * xscreensaver-getimage-file caches the contents of the
+ image directory for a few hours, so consecutive runs
+ won't have to re-list the whole directory tree.
+ * New hacks, `topblock' and `glschool'.
+ * Removed `xteevee' (superceded by `xanalogtv').
+ * Added variable-sized puzzle pieces to `jigsaw'.
+ * Changes to the defaults and command-line options of
+ many hacks to make the .xml files more consistent.
+ * Reap zombies in `glslideshow' and `carousel'.
+ * `sonar' works without setuid on MacOS (dgram icmp).
+ * `xmatrix -mode pipe' displays the text of a subprocess.
+ * `endgame' has higher resolution chess-piece models.
+ * `webcollage' takes a -directory option to get images
+ from a local directory.
+ * The RPM spec file no longer auto-restarts xscreensaver
+ when a new version is installed. Restart it manually.
+Changes since 4.23: * New versions of `cube21', `glsnake', `celtic'.
+ * Backed out a DPMS-related patch that cause desktop
+ flickering with some X servers.
+ * Fixed startup crash in getgroups() when running setuid.
+ * Default to not displaying stderr on the saver window.
+ * Fixed bad free() in "Documentation" button.
+ * Don't try to run hacks that aren't installed.
+ * Minor fixes to various XML config files and man pages.
+Changes since 4.22: * New hacks, `glhanoi', `cube21', `timetunnel',
+ `juggler3d', and `celtic'.
+ * New versions of `tangram', `webcollage', `hypertorus',
+ `polytopes', and `ripples'.
+ * `sonar' is now quiet about unresolvable hosts.
+ * Minor corrections to BASIC code in `apple2'.
+ * xscreensaver-demo now provides an RPM clue when none
+ of the hacks seem to be installed.
+ * Don't install `ant' by default, since there is some
+ Java tool of that name, which was causing confusion.
+ And also it's boring.
+ * Made screen grabbing work again on MacOS 10.4.2.
+ * No longer prints bogus warnings about ClientMessages
+ intended for the window manager.
+ * Ignore unprintable characters in passwd entry field.
+ * Fixed yet another cross-host-display image-loading
+ endian problem.
+ * `xscreensaver-command -watch' and `-time' now work
+ on 64-bit machines.
+Changes since 4.21: * Fixed a bug in the new mouse-motion code that caused
+ the screen to never blank on multi-head non-Xinerama
+ systems. Oops.
+ * New hacks, `interaggregate', `antmaze', `tangram',
+ and `crackberg'.
+ * Minor tweaks to `fiberlamp', `ifs', `slidescreen',
+ `zoom', `sonar', `fireworkx', `whirlwindwarp',
+ `bubble3d', and `rd-bomb'.
+ * Added motion blur to `blinkbox'.
+ * `bsod' now includes Longhorn's "RSOD", and OS/2.
+ * Fixed `-wireframe' usage in most hacks and man pages.
+Changes since 4.20: * New hack: `fliptext'.
+ * Changed default configure installation directories:
+ /usr/bin/ for xscreensaver, etc.;
+ /usr/libexec/xscreensaver/ for hacks;
+ /usr/share/xscreensaver/config/ for xml files.
+ * All the text-manipulating screen savers can have their
+ text source configured via `xscreensaver-demo' now.
+ * xscreensaver.spec now builds three RPMs:
+ base (no hacks); extras (2d hacks); and gl-extras.
+ * Added `-program' and `-front' option to `gltext'.
+ * Added `-shells' to `molecule'.
+ * Fixed text-alpha glitch in `carousel'.
+ * New `pacman': the ghosts can be killed now.
+ * Fixed a bug in screen-grabbing GL hacks where images
+ would be tiled instead of scaled on machines that
+ can't do large textures.
+ * `webcollage' can hit Flickr now.
+ * New (rewritten) implementation of `ifs'.
+ * The unlock dialog can be made to have a "New Login"
+ button that will run `gdmflexiserver'. Experimental!
+ * Fixed non-ASCII display bug in `starwars'.
+ * Configure finds a default for imageDirectory.
+ * "xscreensaver-command -lock" now works even if
+ in "screensaver disabled" mode.
+ * If a bad password is typed while CapsLock is on, the
+ unlock dialog says "CapsLock?" instead of "Sorry".
+ * Mouse motion only counts as activity if the mouse moved
+ more than 10 pixels (so the screen won't unblank every
+ time you bump your desk.)
+ * New mode option "random-same": if you have multiple
+ monitors, this will run the *same* randomly chosen
+ hack on each screen, instead of different ones on each.
+Changes since 4.19: * New hacks, `fiberlamp', `boing', `boxfit', and
+ `carousel'.
+ * Rewrote `glslideshow' again: should be faster now.
+ * Sped up loading of images in GL programs.
+ * `starwars' uses texture-mapped fonts now.
+ * New `bsod' modes: tru64, hppa, and nvidia.
+ * Updates to `webcollage', `juggle', `pinion',
+ `fireworkx', `sonar', `extrusion', `substrate', and
+ `pong'.
+Changes since 4.18: * New hacks, `substrate', `intermomentary', `fireworkx',
+ and `pinion'.
+ * New version of `flow'.
+ * Made /proc/interrupts work again on Linux 2.6.
+ * Made `analogtv' not hog the CPU.
+ * Made analogtv-based hacks work properly on PPC/ARM.
+ * Fixed a bad memory leak in `piecewise'.
+ * Minor updates to `sonar', `molecule', `glmatrix',
+ `galaxy', and `webcollage'.
+ * Removed support for GTK 1.x (everyone uses 2.x now.)
+Changes since 4.17: * Oops, pay no attention to the man behind the curtain.
+Changes since 4.16: * New hacks, `anemotaxis' and `memscroller'.
+ * Fixed a bad bug that caused `vidwhacker' to never die.
+ * Fixed normals and lighting in `polyhedra'.
+ * Don't reuse the window when changing hacks (to work
+ around bugs in some GL implementations.)
+ * Made `xscreensaver-getimage-file' skip thumbnail-sized
+ images.
+ * Fixed endian problem in `barcode' on non-x86.
+ * Updates to `webcollage', `apple2', `fuzzyflakes',
+ `atunnel', and `pacman'.
+ * Timing tweaks to `bubble3d', `bouncingcow', `engine',
+ `gltext', `lavalite', `molecule', `spotlight',
+ `sballs', `boxed', `blinkbox', and `circuit'.
+ * Configure updates for Fedora core 2 / xorg 6.7.0.
+ * Compile without warnings under gcc 3.3.3.
+ * I give up: don't blank or lock the screen if we can't
+ get a keyboard grab. In that case, both choices are
+ bad.
+Changes since 4.15: * New hacks, `polyhedra', `fuzzyflakes', `antinspect',
+ and `providence'.
+ * Minor updates to `webcollage', `bsod', `endgame',
+ `antspotlight', `xmatrix', and `glmatrix'.
+ * Added support for the RANDR (Resize and Rotate)
+ extension to detect when the size of the desktop has
+ been changed while xscreensaver is already running.
+ * Possibly-futile attempt to work around "rdesktop"
+ focus/grab idiocy.
+ * Made `xscreensaver-getimage -file' still work even if
+ imageDirectory is unset.
+ * Convert Latin1 to ASCII in `starwars' and `phosphor'
+ (since the GLUT font only has ASCII glyphs.)
+ * Fixed randomization in `noof'.
+ * Added "GetViewPortIsFullOfLies" preference to work
+ around longstanding XFree86 bug #421.
+ * Made `sonar' subnet pinging work properly on bigendian
+ machines (e.g., PPC.)
+Changes since 4.14: * New hacks, `wormhole', `mismunch', `noof', and
+ `pacman'.
+ * `phosphor' and `apple2' include vt100 emulators now:
+ this means you can do "phosphor -program top", or
+ can use either program as an xterm replacement:
+ "apple2 -text -fast -program 'xemacs -nw'".
+ * `analogtv' (and related) fill the screen better.
+ * The '-gradient' option works in `atlantis' now.
+ * Minor updates to `blinkbox', `queens', `endgame',
+ `glmatrix', `mirrorblob', `blocktube', and `molecule'.

+ * New version of `glsnake' (with many more models.)
+ * Another Windows crash in `bsod'; also HVX/GCOS6/TPS6.
+ * New version of `endgame'.
+ * Screen grabbing works on MacOS X.
+ * Various minor fixes.
+Changes since 4.12: * On Xinerama systems, xscreensaver now runs one hack on
+ each monitor (just like in "real" multi-head mode)
+ instead of running one hack stretching across all the
+ screens. Note that for this to work with any 3rd party
+ screensavers, they must update their "vroot.h" file.
+ * `webcollage' and `vidwhacker' display images using
+ `xscreensaver-getimage' now.
+ * Added `ljlatest' script for use with `starwars' and
+ `phosphor'.

+ wimpier video cards now.
+ * Various portability tweaks.
+Changes since 4.09: * New hacks, `cloudlife' and `klein'.
+ * Added Apple ][+, HPUX, and OS/390 sessions to `bsod'.
+ * Added some Matrix Reloaded text to `xmatrix'.
+ * Updates to `webcollage', `eruption', `jigglypuff',
+ `metaballs', and `endgame'.
+ * Completely ignore the `memoryLimit' setting now,
+ since it was still causing people GL grief.
+ * Various minor fixes.
+Changes since 4.08: * New hacks, `flyingtoasters', `bouncingcow',
+ `jigglypuff', and `glslideshow'.
+ * More models in `engine'.
+ * Rewrote `xscreensaver-getimage' to remove reliance on
+ external image loaders (xv, chbg, xloadimage, etc.)
+ and to reduce flicker when loading files.
+ * Made `gflux' and `flipscreen3d' be mouse-spinnable.
+Changes since 4.07: * New hacks, `atunnels' and `piecewise'.
+ * Physics improvement in `fluidballs'.
+ * Various fixes for XDarwin systems (X11 on MacOS X.)
+ * Added -clock option to `barcode'.
+ * Minor fixes to `endgame', `flurry', `flipscreen3d',
+ and `gflux'.
+Changes since 4.06: * New hacks, `flurry', `metaballs', `eruption',

+ * Bug fixes for running xscreensaver to a remote XFree86
+ display (which nobody would ever do...)
+ * Updated `webcollage' (faster Alta Vista searching.)
+ * Updated `glplanet' so the sun sets in the west.
+ * Updated `sproingies' with smooth, unsegmented surfaces.
+ * Fixed Perl version-sensitivity in
+ `xscreensaver-getimage-file'.
+ * Fixed GTK2 scrolling bug in `xscreensaver-demo'.
+Changes since 4.05: * New hack, `glblur' (disabled by default, since it
+ requires fast OpenGL texture support.)
+ * New hack, `halftone'.
+ * Updates to `endgame', `queens', `bumps', `glplanet',
+ `engine', and `circuit'.
+ * New version of `menger' that uses far fewer polygons.
+ * Fixed minor bug in `critical' that could cause some
+ bogus X servers to crash.
+ * Better labels in `molecule': the labels now appear to
+ be attached to the atoms, instead of floating in front
+ of the whole scene.
+ * Fixed bug that could rarely cause GL hacks to fail to
+ double-buffer (causing intermittent flickering.)
+ * Fixed a relative-URL-parsing bug in `webcollage'.
+ * Fixed a bug that (sometimes) caused the window manager
+ close box to kill `xscreensaver-demo' with a crash
+ instead of a graceful exit.
+ * Updated xscreensaver.pam to the Red Hat 7.3 way.
+ * More Gnome2-related configure crap.
+ * Updated to latest `config.guess' and `config.sub'.
+ * Fixed occasional core dump in `distort'.
+ * Added a Linux fsck failure and kernel panic to `bsod'.
+ * Added MacOS X kernel panic to `bsod'.
+ * Fixed a bug in `bsod' (all bsod bugs are ironic.)
+ * Fixed a bug that caused `xscreensaver-gl-helper' to
+ print a nonsense visual ID with some versions of
+ `printf': this could cause GL programs to display
+ incorrectly (e.g., flickery.)
+Changes since 4.04: * More `configure' tweaks to try and get things working
+ on systems that both Gtk 1.x and 2.x installed.
+ * New hack, `endgame'.
+ * Minor updates to `gltext'.
+Changes since 4.03: * Support for GTK 2.x / GNOME 2.x.
+ * The `configure' script will now use `pkg-config' if
+ you have it, in preference to `gtk-config', etc.
+ * New hacks, `lavalite', `queens', and `anemone'.
+ * Minor updates to `spheremonics', `gltext', `xmatrix'.
+ * You can use the mouse to manually spin most of the GL
+ hacks now (when they are displaying in a window.)
+ * Fixed a bug in `webcollage' (due to recent Alta Vista
+ url changes) that was causing it to try and load
+ incorrect image URLs.
+ * Made `xscreensaver-getimage' use gdk_pixbuf if it is
+ available: this means that those hacks that load images
+ will no longer rely on "xv", "xloadimage", etc. This
+ will close a race condition that could sometimes cause
+ your desktop background to be changed; and also makes
+ it possible for those programs to operate on image
+ files when running in windowed mode.
+ * `webcollage' can now be used in conjunction with
+ `driftnet' to display images snooped from your local
+ ethernet instead of obtained from search engines.
+ * Added man pages for all the hacks that didn't have
+ them.
+Changes since 4.02: * New hack, `spheremonics'.
+ * Minor updates to `webcollage', `cage', `moebius',
+ `morph3d', `boxed', `circuit', and `helix'.
+ * `pulsar' and `extrusion' can now load texture JPEGs.
+ * `rubik' now does non-square cubes.
+ * `fluidballs' now does various sizes of balls.
+ * `menger' and `sierpinski3d' now also show polygon
+ counts in -fps mode.
+ * `molecule' displays real subscripts in the formulae.
+ * GTK internationalization/localization support.
+ * Better detection of the various versions of libxml.
+ * Upgraded to autoconf 2.53 (from 2.13.)
+Changes since 4.01: * Plugged a few minor leaks in `xscreensaver' and
+ `xscreensaver-demo'.
+ * New hacks, `cubenetic' and `fluidballs'.
+ * Sped up `pipes'.
+ * Fixed sphere projection error in `glplanet'; installed
+ a better image of earth.
+ * Added Win2K and MacOS 1 crashes to `bsod'.
+ * Put back previous (better) version of `forest' that
+ was accidentially downgraded in the last release.
+ * New version of `bumps'.
+ * Made FPS computation in GL hacks more efficient: it
+ will influence the results less, thus resulting in
+ higher (but more accurate) reported frame rates.
+Changes since 4.00: * New hacks: `twang', `glsnake', `boxed', `sballs',
+ and `glforestfire'.
+ * New hacks `apollonian', `euler2d', `juggle',
+ `polyominoes' and `thornbird', from xlockmore.
+ * Merged recent xlockmore changes into `ant', `braid',
+ `demon', `discrete', `drift', `fadeplot', `forest',
+ `grav', `hopalong', `ifs', `laser', `lightning',
+ `lisa', `lissie', `loop', `mountain', `penrose',
+ `rotor', `sierpinski', `slip', `sphere', `spiral',
+ `strange', and `vines'.
+ * Fixed the `gltext' bug that sometimes caused
+ horizontal lines to vanish again. This time for sure.
+ * Sped up `webcollage' by adding a C helper program to
+ replace the PPM pipeline. It also pastes images
+ semi-transparently now.
+ * Added support for the gdk_pixbuf library: if this lib
+ is available, then `blitspin', `xflame', and `flag'
+ can load GIF, JPEG, and PNG images in addition to XPM
+ and XBM.
+ * Fixed a rare race condition where the desktop-grabbing
+ hacks could sometimes leave the screen wedged, if the
+ user moved the mouse exactly when they were grabbing
+ the screen image (it would un-wedge the next time the
+ saver timed out or was activated.)
+ * Fixed incorrect colors in the screen-grabbing GL hacks
+ (`gflux' and `flipscreen3d'.)
+ * Made SIGHUP restart the daemon process (though using
+ `xscreensaver-command -restart' is still the preferred
+ way.)
+ * Tweaks to `xspirograph'.
+ * Minor configure and portability tweaks.
+Changes since 3.34: * Redesigned `xscreensaver-demo' GUI: it now includes
+ small-preview and per-hack configuration dialogs.
+ * Added three new modes of operation: `One Screen Saver',
+ `Blank Screen', and `Don't Blank' (in addition to the
+ historical `Random Screen Saver').
+ * Configure now defaults to installing the hacks in
+ <prefix>/lib/xscreensaver/ instead of <prefix>/bin/.
+ (Most distros already did it this way.)
+ * New GL hacks, `menger', `engine', `flipscreen3d'.
+ * Made `sierpinski3d' be more colorful.
+ * New versions of `xmatrix' and `nerverot'.
+ * Fixed a bug in `starwars' that made the font be drawn
+ with thin lines in -root mode.
+ * Fixed a bad colormap bug in `crystal' that could make
+ *subsequent* hacks malfunction!
+ * Made `gflux' able to grab screen images (`-mode grab').
+ * Updated `webcollage' for recent search engine changes.
+ * Removed most command-line options to `xscreensaver':
+ just edit the ~/.xscreensaver file instead.
+ * Improved behavior on multi-screen and Xinerama systems:
+ the mouse now stays on the screen where the user left
+ it, and the password and splash dialogs always appear
+ on the screen that has the mouse.
+ * Made the splash dialog use more Gtk-like colors;
+ made it have only two buttons, "Settings" and "Help".
+ * Made `sonar' understand `.ssh/known_hosts2' format
+ files, and be better about stripping out illegal
+ addresses.
+Changes since 3.33: * Turned `memoryLimit' off by default, sigh. Apparently
+ some versions of the GL libraries (appear to) allocate
+ hundreds of megs for every GL program, so `memoryLimit'
+ was causing GL programs to malfunction or crash on
+ those systems.
+ * Improved fading on TrueColor XFree86 4.1.x systems.
+ * New GL hack, `circuit'.
+ * Added `fuzz' mode to `decayscreen'.
+ * New version of `whirlygig'.
+ * Added links to `xplanet' and `sphereEversion'.
+ * Fixed rare race condition that could make `sonar' hang.
+ * Fixed potential crash in `speedmine'.
+ * Made `xscreensaver-demo' not crash when imageDirectory
+ was set to a non-existent directory.
+ * Made `xscreensaver-getimage-video' invoke XawTV's
+ `streamer' program better.
+ * Made `phosphor' and `starwars' deal with CR, LF,
+ or CRLF line endings.
+ * Changes for Cygwin compilation environments.
+ * Made `sonar' compile on systems that can't ping.
+ * Configure changes for HPUX 10.20.
+ * Made PAM code work on Red Had 4.2 systems.
+ * Made `xscreensaver-command -deactivate' work when the
+ saver is not active: what that does is reset the idle
+ timer, as if keyboard input had been detected. This
+ was added for the benefit of people writing DVD-playing
+ software: they can now prevent the screensaver from
+ kicking in by sending a -deactivate message once a
+ minute while the movie is playing and not paused.
+ * Various minor portability tweaks.
+Changes since 3.32: * New hacks, `speedmine' and `whirlygig'.
+ * Sped up `pyro', made the explosions look a bit better.
+ * Added better stars to `glplanet' and `starwars'.
+ * Many internal changes to `webcollage'.
+ * Some new options to `attraction'.
+ * Minor fix to `noseguy' to avoid un-erased pixels.
+ * Rewrote the screen-eraser effects so that they complete
+ in the same amount of time regardless of how slow
+ your X server is (some of them were glacial on servers
+ with slow blitting.)
+ * Fixed a potential free memory reference that could
+ sometimes cause a crash at startup.
+ * Possibly fixed a problem that could cause the daemon
+ to crash with an X error. I was never able to
+ reproduce this problem, but I think I might have
+ figured out what caused it.
+ * Worked around a problem that caused PAM authentication
+ to fail on some Red Hat 7.x systems.
+ * Added a `memoryLimit' parameter that controls the
+ amount of memory a graphics hack may allocate: if they
+ try to allocate more than this, malloc() will fail
+ (and they will exit or (safely) crash, rather than
+ hogging memory.) Default is 50M.
+ * Made `gnome-help-browser' be the default way to display
+ man pages in `xscreensaver-demo', if running on a
+ GNOME system.
+Changes since 3.31: * The image-manipulating hacks (`slidescreen', etc.) can
+ now operate on randomly chosen image files from disk,
+ or on frames captured from the system's video input,
+ instead of (or in addition to) manipulating images of
+ the desktop.
+ * Rewrote `vidwhacker' to use the new image-grabbing
+ mechanism.
+ * Made fading work on TrueColor XFree86 4.x systems.
+ * Fixed a subtle rendering bug in `atlantis' (the fish
+ were inside out!)
+ * Made `atlantis' have a texture simulating light
+ reflections from the surface of the ocean.
+ * Fixed up label placement in `molecule'.
+ * Better color bars in `xteevee'.
+ * Made `install-strip' not try to strip scripts.
+Changes since 3.30: * Put in more sensible defaults for DPMS, and updated
+ the documentation to reflect the fact that all your
+ DPMS settings are now belong to xscreensaver.
+ * Fixed the `xscreensaver.spec' file so that `--force'
+ is no longer needed.
+ * New versions of `rotzoomer' and `nerverot'.
+ * Fixed an OSF/1 compilation problem in `molecule'.
+Changes since 3.29: * New hacks, `molecule', `dangerball', and `rotzoomer'.
+ * New version of `gflux'.
+ * Made `gltext' able to display the current time.
+ * Fixed a floating-point-precision problem in `gltext'
+ that sometimes caused horizontal lines to vanish.
+ * Removed the `-window-id' option from the hacks:
+ it never worked right, and was unnecessary.
+ * Made the `starwars' hack use thicker lines, antialias
+ the text, and fade out at the far edge instead of just
+ dropping off.
+ * Fixed an SHM segment leak in `moire'.
+Changes since 3.28: * Better rendering of the new logo.
+ * New hack, `gltext'.
+ * Added `-planetary' option to `gears', to draw a
+ different kind of gear system.
+ * Made motion and rotation be smoother in `gears',
+ `glplanet', `moebius', `rubik', and `sierpinski3d'.
+ * Improved coloration in `sierpinski3d'.
+ * Made the GL hacks react to window size changes.
+ * Made most of the GL hacks take a -fps option (like
+ `pulsar' did), so you can use them to benchmark your
+ 3D hardware.
+ * Fixed the previous fix to `sonar'.
+ * Minor fix to `nerverot'.
+ Made sonar able to ping hosts on DEC OSF1.
+ * Eliminated a bogus "didn't get enough colors" warning
+ in some of the hacks.
+Changes since 3.27: * New logo for xscreensaver!
+ * New hacks, `starwars' and `stonerview'.
+ * Made the motion of the bouncing ball in `stairs' be a
+ little less jerky.
+ * Made newly-added screenhacks be added to .xscreensaver
+ automatically: if there are hacks in the app-defaults
+ file that are not also in ~/.xscreensaver, they will
+ be added to the end of the list.
+ * Redid the `Screensaver Options' part of the control
+ panel; xscreensaver now lets you configure your DPMS
+ settings.
+ * Fixed some Makefile problems with non-GL builds.
+ * Fixed detection of MesaGL for version 3.3.
+ * Better workaround to Red Hat 7.0's broken gcc.
+ * Added Sparc Solaris kernel panic to `bsod'.
+Changes since 3.26: * New hacks: `zoom' and `whirlwindwarp'.
+ * Fixed a free-memory-reference bug in `sonar'.
+ * Better error handling when there are no suitable GL
+ visuals.
+ * Added diagnostic dialog when xscreensaver-demo is
+ unable to launch xscreensaver (e.g., when running as
+ root.)
+ * Fixed a bug that caused screenhack argument changes
+ to be ignored when xscreensaver-demo was running as
+ root (if "root" and "nobody" have different home
+ directories.)
+ * Made the programs default to ":0" if $DISPLAY is unset.
+ * Made the `-verbose' output include information about
+ which server extensions were supported at compile time.
+ * Worked around Red Hat 7.0's broken gcc 2.96.
+ * Updated default delays on the GL hacks to look better
+ on machines with super-fast 3D hardware.
+ * Install `screensaver-properties-capplet' to work around
+ the usual egregious GNOME lossage.
+Changes since 3.25: * Added "enabled" checkboxes in the list of hacks in
+ xscreensaver-demo (Gtk version only.)
+ * New hacks `hyperball', `xrayswarm', and `gflux'.
+ * New versions of `nerverot', `galaxy', and `hypercube'.
+ * Small fixes to `phosphor', `shadebobs', `xflame',
+ and `sonar'.
+ * Added external helper program `xscreensaver-gl-helper'
+ to figure out which X visual to use for OpenGL
+ programs.
+ * Configure updates for XFree86 4.0, and for BSD.
+ * Made it be more tolerant of bogus /etc/group files.
+ * When installing the PAM config file, first try to just
+ copy an existing "xdm" or "login" config file, so that
+ xscreensaver does authentication in the same way as the
+ rest of the system.
+Changes since 3.24: * New hack, `nerverot'.
+ * Added BSD kernel panic to `bsod'.
+ * New version of `shadebobs'.
+ * New version of `petri'.
+ * Updated `webcollage' to handle recent Altavista URL
+ format changes; made it search the AP photo gallery.
+ * Revamped command-line options of `sonar' and made it
+ properly handle subnets.
+ * The `bubbles' hack can now trickle up or down the
+ screen.
+ * The `xsublim' hack can now read its text from programs.
+ * Support for GLE version 3 in `extrusion'.
+ * Fixed compilation problems in `maze'.
+ * Fixed a rare crash in `flow'.
+ * Fixes for minor installation problems.
+Changes since 3.23: * Added `-ignorant' option to `maze' hack.
+ * Updates to `critical', `bsod', `xflame', and `flow'.
+ * Added support for Kerberos 5 (via its Kerberos 4
+ compatibility layer.)
+ * Fixed a bad leak in `xteevee'.
+ * Updated `webcollage' to handle recent Altavista URL
+ format changes.
+ * Removed xscreensaver-demo's `Ok' and `Cancel' buttons,
+ since they were confusing people: all changes are now
+ instantanious.
+ * Made xscreensaver-demo install itself into the Gnome
+ Control Center.
+Changes since 3.22: * Fixed some misplaced text fields in the Motif version
+ of xscreensaver-demo; fixed a crash in the Gtk version
+ that would happen if the programs list was empty.
+ * Fixed a recently-introduced bug in `pulsar'.
+ * Made `sierpinski3d' use solid tetrahedrons instead of
+ points.
+ * Added `-trace' option to `xmatrix'.
+ * Added new hacks `xteevee' and `xspirograph'.
+Changes since 3.21: * Fixed some bugs in xscreensaver-demo.
+ * Rewrote the Motif version of xscreensaver-demo to
+ match the new Gtk version.
+ * The Athena toolkit is no longer supported.
+Changes since 3.20: * Tweaked the xscreensaver-demo UI (Gtk only.)
+ * Fixed a few visual selection bugs. I think the proper
+ GL visual should be used with nVidia systems now.
+ * Made the Makefiles obey $install_prefix.
+ * Made the `xscreensaver.spec' file able to generate both
+ GL and non-GL packages simultaneously.
+Changes since 3.19: * Added new hacks `ripples' and `sierpinski3d'.
+ * Made `xscreensaver-command -exit' be silent when no
+ screen saver was running (instead of complaining.)
+ * Made `webcollage' and `vidwhacker' use `xloadimage'
+ when available (in addition to `xli' and `xv'.)
+ * Improved memory usage in `petri' and gave it a hard
+ cap on how much memory it can allocate.
+ * Added `-watch' option to `xscreensaver-command'.
+ * Made `xscreensaver-demo' come up with the
+ most-recently-run hack selected by default.
+ * Rewrote the Gtk version of `xscreensaver-demo'.
+ It's a lot easier to use now.
+ * Extended the format of the programs list in the
+ .xscreensaver file, for the benefit of the new
+ capabilities of `xscreensaver-demo'.
+ NOTE: you might want to delete your ~/.xscreensaver
+ file and allow it to be re-created! The old one
+ should still work, but xscreensaver-demo won't be as
+ pretty.
+Changes since 3.18: * Fixed gcc dependencies in `bumps' and `ccurve'.
+ * New hack, `extrusion'.
+ * Some of the web sites that `webcollage' was using as
+ its sources changed formats; tweaked it to understand
+ the current layouts.
+ * Added typeahead in the password dialog: if the screen
+ is locked, and you unlock it by typing a character,
+ that key will be automatically inserted in the
+ password dialog (unless it is Return, Enter, Space,
+ or a non-printing key like Shift.)
+ * Made `xmatrix' take a `-small' option, since some
+ folks with tiny screens prefer a smaller font.
+Changes since 3.17: * New versions of `shadebobs', `lmorph', and `distort'.
+ * Added `ccurve', `blaster', and `bumps' hacks.
+ * Replaced `forest' hack with a rewritten version.
+ * Worked around a Xinerama server bug.
+ * Fixed a bug I introduced in 3.10 that caused some
+ hacks to print out superfluous warnings about not
+ having gotten enough colors.
+ * Made `sproingies' obey the `-delay' option.
+ * Fixed a portability bug in `shadebobs'.
+ * Made `webcollage' and `vidwhacker' use `xli' in
+ preference to `xv', if it is available.
+ * Added a new source of images to `webcollage'.
+ * If running under KDE, xscreensaver will add itself to
+ KDE's list of screensavers (via xscreensaver.kss.)
+ * Improved detection of GL libraries.
+ * Made the password dialog include the date and time.
+Changes since 3.16: * New version of `webcollage' -- deals better with
+ corrupted images, and can use an http proxy.
+ * New hack, `xsublim' (run it in the background,
+ rather than adding it to the programs list.)
+ * The xscreensaver daemon was leaking a file descriptor
+ each time you edited your .xscreensaver file. Fixed.
+Changes since 3.15: * New version of `shadebobs'.
+ * Improved image selection in `webcollage', and sped it
+ up slightly.
+ * Made configure find the right version of perl.
+ * Rewrote the CGI part of `webcollage'.
+ * `make clean' was deleting some things it shouldn't.
+ * Fixed a typo in the default programs list.
+Changes since 3.14: * Added `webcollage' and `shadebobs' hacks.
+ * Added a `-stdout' arg to `vidwhacker' so that it can
+ be used in a pipeline.
+ * Made `petri' use less memory.
+Changes since 3.13: * Various improvements to the Gtk port.
+ * Turned off PAM by default on Solaris, since PAM seems
+ generally to be misconfigured out-of-the-box.
+ * Made the `--without-gtk' configure option work.
+ * Made configure check the Gtk version number, since it
+ requires 1.2.
+ * Fixed a bug in the code that attempted to prevent
+ changes of screen resolution while the screen is
+ locked.
+ * Fixed a race condition in `xscreensaver-demo' that
+ could cause an X error at startup.
+ * Added `-transparent' option to `deluxe'.
+ * Added `petri' hack.
+Changes since 3.12: * Ported `xscreensaver-demo' to Gtk.
+ * Made it possible to build Motif, Gtk, and Athena
+ versions of `xscreensaver-demo' in the same directory
+ without reconfiguring.
+ * Made `xscreensaver-demo' chase symlinks before writing
+ the .xscreensaver file, so that if .xscreensaver is
+ itself a symlink, the underlying file will be replaced
+ instead.
+ * Some Makefile and configure tweaks for Solaris and
+ FreeBSD.
+ * Made it possible to set the fire color in `xflame'.
+ * Made transparency work in TrueColor (for `goop' and
+ `qix'.)
+ * Fixed a multi-head bug introduced by the virtual
+ viewports stuff.
+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.
+ * Reduced the amount of code that runs before root
+ privileges are disavowed: "normal" and "shadow"
+ passwords now do some initialization as root, but the
+ PAM and Kerberos authorization schemes will be
+ initialized while running as "nobody". Supposedly
+ this closes a potential security hole when using
+ Kerberos.
+ * Added some more sanity checking to configure.
+Changes since 3.08: * Added `compass', `squiral', `xflame', `wander',
+ `spotlight', and `critical' hacks.
+ * Added some new modes to `decayscreen'.
+ * Made `deluxe' work in monochrome.
+ * Generalized usage of the Double-Buffer server extension
+ in several hacks (`compass', `deluxe', `interference',
+ `kumppa', and `moire2'.)
+ * Fixed another visual-depth problem in `rd-bomb'.
+ * The screen saver will now defer blanking if neither
+ the keyboard nor the mouse could be grabbed. Instead,
+ it will just try again in a few minutes. This fixes
+ a bad interaction between xscreensaver and programs
+ like VMware that hold the mouse and keyboard grabbed
+ for a long time.
+ * Added a new erase mode (expanding spiral.)
+Changes since 3.07: * Fixed some bugs in my port of `t3d'.
+ * Added `penetrate' and `deluxe' hacks.
+ * When linking against Motif 2.x, also link against XPM.
+ * Added support for using /proc/interrupts for idle
+ detection on Linux. Now xscreensaver shouldn't kick
+ in when the user is active on a non-X virtual console.
+ * Upgraded to autoconf 2.13.
+Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
+ in properly; check for _Xsetlocale in -lXintl.)
+ * Portability fixes for sonar.c.
+ * Fixed a compilation problem when you have GL but don't
+ have XPM.
+ * Made configure notice when MesaGL requires -lpthread.
+ * Made `flame' ignore SIGFPE (not sure if this is the
+ right fix; it seems only to be needed on FreeBSD.)
+ * Kludged `rd-bomb' work on visuals that are of depth 24
+ but that *do not* support pixmaps of depth 32.
+ * Fixed `halo' to work properly in TrueColor.
+ * Changed `xscreensaver.spec' to install the hacks in
+ /usr/X11R6/lib/xscreensaver/ by default, since that's
+ where recent Red Hat distributions put them.
+ * Added `t3d' hack.
+ * Updated versions of `crystal', `hopalong', and `flow'
+ from xlockmore.
+ * Imported `demon' and `loop' modes from xlockmore.
+Changes since 3.05: * Oops, the "default-n" visual descriptor was broken;
+ it was always installing a colormap if the
+ `installColormap' preference was set, meaning that
+ `xearth', `xv' and friends were using the wrong
+ colors on 8-bit systems.
+ * Turned off HAVE_PING in `sonar', since it compiles
+ on some Linux systems, but not others of similar
+ vintage...
+Changes since 3.04: * Fixed an off-by-1 in `distort'.
+ * Added `sonar' hack.
+ * New version of `glplanet' (with stars.)
+ * Made all hacks exit when you type `q' or `ESC' at them,
+ and made them obey the WM_DELETE_WINDOW ClientMessage.
+ * Fixed a nonfatal buffer overrun in lament (note:
+ lament still doesn't work with MesaGL 3.0: it dies in
+ lambda_textured_triangle1(), which is Mesa's bug, not
+ mine.)
+Changes since 3.03: * Added an `xscreensaver.spec' file, to make it easier
+ for other folks to generate RPMs.
+ * Made the password code work on HPUX in the situation
+ where: ``enhanced security'' is available; but not
+ used; but the user typed a password more than 8
+ characters long anyway. FTSOHPUX.
Changes since 3.02: * Made locking work when passwd aging is enabled.
* Added support for PAM (Pluggable Authentication
Modules.) It is still turned off by default, though,
Changes since 1.8: * Added demo mode, and locking.
* Added `maze' hack.
* Added `norotate' option to `rocks' hack.
+Changes since 1.4: * Works when run from XDM before anyone logs in.
+ * Sped up `imsmap'.
+ * Can use `xv' as a slideshow without using up colormap
+ entries while the screen is not blanked.
+ * Fixed a BadDrawable error in non-XIdle mode.
+ * Added `blitspin' and `imsmap'.
+Changes since 1.0: * Current list of included hacks is now: qix, helix,
+ rorschach, attraction, greynetic, rocks, pyro,
+ hopalong, and noseguy.
