XScreenSaver
a collection of
free screen savers
for X11 and MacOS
By Jamie Zawinski
and many others
https://www.jwz.org/xscreensaver/
===============================================================================
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.
To compile for a Unix system with X11:
./configure
make
make install
If you are on an "apt"-based system, "apt-get build-dep xscreensaver"
might install most of the compilation dependencies.
To compile for MacOS X or iOS:
Use the included XCode project. Requires XCode 6 and MacOS X 10.8
or newer.
To compile for Android:
See android/README.
Interested in writing a new screen saver?
See the README.hacking file.
===============================================================================
XScreenSaver has an extensive manual -- please read it!
===============================================================================
5.36 * New hacks, `discoball', `cubetwist', `cubestack', `splodesic'
and `hexstrut'.
* OSX: loading image files works in `dymaxionmap', `glplanet',
`lavalite', `pulsar', `gleidescope' and `extrusion'.
* Several new programs in `m6502'.
* `rotzoomer -mode circle'.
* Better titles in `photopile'.
5.35 * New hacks, `dymaxionmap', `unicrud', `energystream', `raverhoop'
and `hydrostat'.
* Added Windows 10 to `bsod'.
* X11: ignore WM_USER_TIME property changes with days-old timestamps.
Thanks, KDE.
* MacOS, iOS: Better fonts in `BSOD' and `memscroller'.
* MacOS 10.8 or later and iOS 6.0 or later are now required, since
Xcode 6 can no longer build executables that work on older OSes.
* Many, many Android improvements.
* iOS: Fixed rotation to work with the new iOS 8+ API.
* X11: `pong' is now playable.
5.34 * Fixed a crash when hot-swapping monitors while locked.
* Fixed some incorrect output from `xscreensaver-command -watch'.
* Various OSX and iOS performance improvements.
5.33 * New hacks, `splitflap' and `romanboy'.

on X11 with Xft (instead of only on OSX/iOS) in `fontglide',
`noseguy', `fliptext', `starwars', and `winduprobot'.
The other text-displaying hacks (`apple2', `phosphor', `xmatrix',
and `gltext') also now accept UTF-8 input, though they convert it
to Latin1 or ASCII.

* Make cel-shading sort-of work in `skytentacles' on iOS.
* Fixed dragging-to-rotate on rotated iOS devices, I think.
* Dragging has inertia now.
* Most hacks respond to mouse-clicks, double-taps and swipes as
meaning "do something different now".
* Reworked OpenGL fonts.
* The OSX auto-update installer wasn't working. This time for sure?
* Various minor fixes.
5.29 * Downgraded to Xcode 5.0.2 to make it possible to build savers
that will still run on 10.6 and 10.7. Sigh.
* Updated `webcollage' for recent changes.
5.28 * Fixed some compilation problems and intermittent crashes.
* Turned off the OSX 10.6 enable_gc hack. It didn't work.
5.27 * New hacks, `tessellimage' and `projectiveplane'.
* Added support for pthreads, because Dave Odell is a madman.
* Updated `webcollage' for recent changes.
* Minor iOS tweaks to the `analogtv' hacks.
* X11: Don't assume Suspend = 0 implies "No DPMS".
* Minor updates to `boxed' and `klein'.

* Fixed possible crash in OSX preferences.
* OSX Performance improvements.
* Plugged some leaks.
5.26 * More auto-updater tweaks.

* iOS and OSX: fixed a font-metrics bug.
* iOS: Fixed aspect ratio bug in non-rotating apps when launched in
landscape mode.
* Made `quasicrystal' work on weak graphics cards.
* iOS: fixed `ifs'.
* Better compression on icons, plists and XML files: smaller
distribution and installation footprint.
* Reverted that DEACTIVATE change. Bad idea.
* `Phosphor' now supports amber as well as green.
5.22 * New hacks, `kaleidocycle', `quasicrystal', `unknownpleasures' and
`hexadrop'.
* Performance improvements for `interference'.
* Fixed possible crashes in `apple2', `maze', `pacman', `polyominoes',
`fireworkx', `engine'.
* Fix for `bumps' in 64 bit.
* Fixed preferences crash on old iOS 5 devices.
* Fixed "Shake to Randomize"; display name of saver.
* Fixed weirdness with "Frame Rate" sliders on iOS.
* Fixed rotation problems with `pacman', `decayscreen'.
* Better dragging in `fluidballs'.
* Ignore rotation in hacks that don't benefit from it.

password dialog box.

now requires a login to get any feeds.

* Various fixes.
5.17 * More iOS tweaks.
* Fixed some compilation problems.

* `phosphor' and `apple2' can now be run as standalone terminal
emulator applications on MacOS.
* `photopile' sped up.
* New molecule in `molecule'.
* "Upgraded" to XCode 4.0, which means that MacOS 10.4 PPC builds are
impossible, and Intel is now required.
* Turned on LC_CTYPE on Linux; maybe Japanese password entry works
now?
5.14 * Fixed crash in Blank Only Mode when DPMS disabled.
* Added "Quick Power-off in Blank Only Mode" option.
* BSOD GLaDOS.
5.13 * Optionally enabled full-scene OpenGL antialiasing. Set the resource
`*multiSample' to true if doing so doesn't kill performance with
your video hardware.
* New version of `glhanoi'.
* Image-loading hacks that display the file name now also display the
sub-directory (xscreensaver-getimage now returns relative paths
under imageDirectory).
* Passwords that contain UTF-8 non-Latin1 chars are now typeable.
* Numerous minor stability fixes.
5.12 * Big speed improvement on OSX for heavy XCopyArea users (`xmatrix',
`moire2', `phosphor', etc.)

for systems where RANDR lies and says the screen size is 0x0.
* When the password dialog has timed out or been cancelled, don't pop
it right back up a second time.
* Password timeouts/cancels don't count as "failed logins".
* Retired some of the older, less interesting savers: say goodbye to
`bubbles', `critical', `flag', `forest', `glforestfire', `lmorph',
`laser', `lightning', `lisa', `lissie', `rotor', `sphere', `spiral',
`t3d', `vines', `whirlygig', and `worm'.
* Merged `munch' and `mismunch'.
* Updated `webcollage' to use twitpic.com as well.
5.07 * Xinerama/RANDR tweaks for old-style multi-screen.
* Added bumpy skin and cel shading to `skytentacles'.
* `flipflop' can load images onto the tiles.
* Fixed the bouncing ball in `stairs'.
* Added the missing Utah Teapotahedron to `polyhedra'.
* `blitspin' works with color images on MacOS now.
* Added transparency to `stonerview'.
* Improved layout of the preferences dialogs: they should all now be
usable even on ridiculously tiny laptop screens.
* MacOS preferences text fields now prevent you from entering numbers
that are out of range.
* Added "Reset to Defaults" button on X11.
* Added relevant Wikipedia links to many of the screen saver
descriptions.
* All hacks support the `-fps' option, not just GL ones.
* The `-fps' option now shows CPU load.
5.06 * Xinerama/RANDR fixes: this time for sure. It should now work to
add/remove monitors or resize screens at any time.
* New hack, `skytentacles'.
* New version of `gleidescope'.
* Added the `-log' option to the xscreensaver daemon, since a truly
shocking number of Linux users seem to have no idea how to redirect
output to a file.
* Added `-duration' arg to most image-loading hacks, so that they pick
a new image every few minutes.
* Added an ATM crash to `bsod'.
5.05 * New hacks, `cubicgrid', `hypnowheel', and `lcdscrub' (which isn't
really a screen saver).
* Updates to `m6502' and `gears'.
* Fixed double-buffering problems in `cubestorm' and `noof'.
* Better handling of horizontal scroll wheels.
* Attempt to work around latest Xinerama braindamage: if the server
reports overlapping screens, use the largest non-overlapping
rectangles available.
* Don't warning about receipt of bogus ClientMessages, since Gnome's
just never going to stop sending those.
* Worked around MacOS 10.5 perl bug that caused the text-displaying
hacks to fail on some systems.
* Hopefully fixed font-related System Preferences crashes in MacOS
savers.
* The recent PAM changes broke the "Caps Lock" warning in the password
dialog, the failed login warnings, and syslogging. Fixed all that.
5.04 * Fixed a possible crash in the unlock dialog (more fallout from the
recent PAM changes...)
* New hacks, `moebiusgears', `abstractile', and `lockward'.
* Rewrote `gears' to use better (involute) gear models, and to be more
random.

`circuit', `endgame', `crackberg', `flipflop', `flipscreen3d',
`fliptext', and `carousel'.
* Enabled multi-threaded OpenGL on MacOS.
5.01 * 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.
5.00 * 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.

* `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.

* Don't try to run hacks that aren't installed.
* Minor fixes to various XML config files and man pages.
4.23 * 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.
4.22 * 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.
4.21 * 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.
4.20 * 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'.
4.19 * 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.)
4.18 * Oops, pay no attention to the man behind the curtain.
4.17 * 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.
4.16 * 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.)
4.15 * 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'.
* Integrated SuSE's "external passwd helper" support.
* Marginally better /tmp handling in various programs.
* Updated config defaults for xplanet 1.0.3.
* Portability fixes.
4.14 * New hacks, `fontglide', `apple2', `xanalogtv', `pong',
`gleidescope', `mirrorblob', and `blinkbox'.
* 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.
4.13 * 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'.
4.12 * New GL hacks, `flipflop', `antspotlight', and `polytopes'.
* Added VMS to `bsod'.
* Compile without warnings in "gcc -pedantic".
* Updates to `webcollage' and `queens'.
* Fixed a bug that could cause PAM to hang.
4.11 * New hacks, `hypertorus', `cubestorm', `glknots', `blocktube', and
`glmatrix'.
* Updates to `cloudlife', `engine', `xmatrix', and `sonar'.
* Rewrote `glslideshow': it should work on somewhat wimpier video
cards now.
* Various portability tweaks.
4.10 * 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.
4.09 * 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.
4.08 * 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'.
4.07 * New hacks, `flurry', `metaballs', `eruption', `popsquares', and
`barcode'.
* Minor updates to `maze' for high density mazes.
* Added double buffering to `fluidballs' and `whirlygig'.
* 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'.
4.06 * 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.)
4.05 * 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'.
4.04 * 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.
4.03 * 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.)
4.02 * 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.
4.01 * 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.
4.00 * 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.
3.34 * 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.
3.33 * 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.
3.32 * 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.

surface of the ocean.
* Fixed up label placement in `molecule'.
* Better color bars in `xteevee'.

* Made `gltext' able to display the current time.
* Fixed a floating-point-precision problem in `gltext' that sometimes
caused horizontal lines to vanish.

existing "xdm" or "login" config file, so that xscreensaver does
authentication in the same way as the rest of the system.
3.25 * New hack, `nerverot'.
* Added BSD kernel panic to `bsod'.
* New version of `shadebobs'.

layer.)
* Fixed a bad leak in `xteevee'.

were confusing people: all changes are now instantanious.
* Made xscreensaver-demo install itself into the Gnome Control Center.
3.23 * 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.

version.
* The Athena toolkit is no longer supported.
3.21 * Tweaked the xscreensaver-demo UI (Gtk only.)

should be used with nVidia systems now.

* Made the `xscreensaver.spec' file able to generate both GL and
non-GL packages simultaneously.
3.20 * Added new hacks `ripples' and `sierpinski3d'.
* Made `xscreensaver-command -exit' be silent when no screen saver was
running (instead of complaining.)

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.
3.19 * 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.)

* 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.
3.17 * 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.
3.16 * 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'.

3.15 * 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.
3.14 * 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 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.

error at startup.
* Added `-transparent' option to `deluxe'.

3.13 * 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'.)
