XScreenSaver
a collection of
free screen savers
for X11 and MacOS
By Jamie Zawinski
and many others
http://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 on a Unix system with X11:
./configure
make
make install
To compile on MacOS X:
Use the included XCode project. Requires XCode 2.4 and MacOS X 10.4.0
or newer.

See the README.hacking file.
===============================================================================
XScreenSaver has an extensive manual -- please read it!
===============================================================================
Changes since 5.04: * 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.
Changes since 5.03: * 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.
* Minor updates to `cwaves', `voronoi', `deco',
`glcells', `rd-bomb', `fireworkx' and `webcollage'.
* `pong' can now display the current time as the score.
* `xmatrix -mode pipe' works better.
* Minor tweaks for compilation on MacOS 10.5.0.
Changes since 5.02: * New hacks, `cwaves', `glcells', `m6502', and `voronoi'.
* Minor fixes to `bsod'.
* Fixed possible crash with PAM USB-dongle auth.
* Updated `webcollage' to track recent Google Images
and Flickr changes.
Changes since 5.01: * Reworked PAM code to support fingerprint readers, etc.
* Ported 'webcollage' to OSX.
* Added OSX 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 OSX.
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 OSX (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'.
* Integrated SuSE's "external passwd helper" support.
* Marginally better /tmp handling in various programs.
* Updated config defaults for xplanet 1.0.3.
* Portability fixes.
Changes since 4.13: * 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.
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'.
Changes since 4.11: * 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.
Changes since 4.10: * 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.
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',
`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'.
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
/lib/xscreensaver/ instead of /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,
since it doesn't seem to work on Solaris 2.6, and has
been behaving erratically on Red Hat 5.1.
* Made each possible authentication method be tried in
turn until one succeeds; this means that Kerberos is
being used, we will first check Kerberos, and if that
fails, will then consult the local password file.
Likewise with PAM.
* Save and restore the bits under the passwd dialog,
to avoid leaving a black rectangle behind when
unlocking is cancelled.
Changes since 3.01: * Not everyone has sys/select.h, sigh...
Changes since 3.00: * Some fixes to `reflect'.
* Configure tweaks.
* Made it log unsuccessful attempts to unlock the screen
to syslog.
* Fixed a bug where `xscreensaver-demo' could be seeing
a different programs list than `xscreensaver' did.
Changes since 2.34: * The xscreensaver daemon no longer links against Motif
or Athena: demo-mode and the preferences panel are no
longer built in to the daemon, but are now handled by
an external program, `xscreensaver-demo'.
(I decided that this, along with the recent addition
of the `.xscreensaver' config file, justified bumping
the version number to 3.00, since this is a fairly
major architectural change.)
* Lines in the `*programs' resource may now begin with
the character "-", meaning "don't run this hack."
In this way, it's possible to disable a hack without
throwing away the information about it (making it
easier to change your mind later.) Eventually the
preferences/demo mode GUI should represent this as a
checkbox or something.
* Fixed a short race condition where it was possible for
xscreensaver to die with a BadWindow error if it was
blanking the screen just as another window was being
deleted.
* Made it possible to disable specific modes in `bsod'.
Changes since 2.33: * Fixed a bug that was making `pipes' generate way too
many valves. Made the viewpoint in `pipes' be selected
randomly instead of always being -10 degrees.
* Fixed a bug in the XSHM code, in the case where the
server supports the XSHM extension but is not the same
machine as the client.
* Made `rd-bomb' default to taking up the whole screen.
* Made it not try to do fading/unfading if no PseudoColor
visuals exist.
* Initial attempt at supporting VT-locking (doesn't work
yet.)
* Eliminated the `captureStdout' resource; now
`captureStderr' controls both streams.
* Added `-capture-stderr' and `-no-capture-stderr'
command-line arguments.
* Added `glplanet' hack.
* When a hack is selected with `xscreensaver-command
-select', that hack will be used until further notice
(until the saver turns off, or another activation
command is issued.)
Changes since 2.32: * Made `xscreensaver-command' print error messages:
the xscreensaver daemon now responds to ClientMessage
events by writing a response message on a window
property, instead of just writing to its stderr.
* Made the ~/.xscreensaver file be automatically reloaded
when the file date changes.
* The password dialog and splash screen no longer depend
on Motif or Athena. This should clear up a number of
focus problems, and is the first step on the path
toward moving all of the Motif/Athena/whatever code
out of the xscreensaver daemon, and into external
processes.
* Don't complain about LessTif 0.86 any more, since the
new password dialog makes that problem go away.
* Configure tweaks for Irix 6.5, SunOS 5.something.
* New `-reflect' option to `distort'.
Changes since 2.31: * Added reading and writing of a ~/.xscreensaver file,
so that the Preferences panel can save its settings.
* New version of `rubik'.
* Added `-select N' argument to `xscreensaver-command'.
* Oops, left out some of the `bubbles3d' files...
Changes since 2.30: * The cursor was invisible in the password dialog. Fixed.
* Made configure warn against MesaGL 2.6.
* Fixed X error at startup when using non-default visual.
* New version of `crystal', `ant', and `atlantis' from
xlockmore.
* New hack, `bubble3d'.
* Added some new modes to `bsod'.
Changes since 2.29: * Changed the order in which -lSM and -lICE are linked
to be after Motif instead of before (Lesstif on Irix
needs this.)
Changes since 2.28: * Work around a bash bug in configure.
* Tweaked HPUX paths again. FTSOHPUX.
* Made configure recommend against LessTif 0.86, due
to a bug in that version that causes a security hole
in the screen locking code. LessTif 0.87 will fix it.
* Made all of the `--with' options to `configure' accept
a directory option as well (so that --with-motif=/FOO
will add -I/FOO/include -L/FOO/lib). I believe this is
the Configure Party Line of how do to such things.
* Fixed a bug where the mouse was left un-grabbed
after the first time the graphics hack was changed
(simplified all of the mouse-grabbing logic.)
* Maybe possibly perhaps made `vidwhacker' really not
leave stray xv windows around. This time for sure.
* Added a new erase mode (random dots fizzling out.)
* Added `-prefs' argument to `xscreensaver-command',
that brings up the Preferences dialog directly (it
seems that nobody ever noticed the `Preferences' button
on the Demo Mode dialog, maybe this will help.)
* Added a splash screen. Turn it off with *splash:false.
Changes since 2.27: * Better macsbug text in `bsod'.
* New version of `distort' with many new modes.
* Plugged a leak in `coral'.
* Tweaked configure for HPUX.
* Removed some compiler warnings.
* More consistent usage of stderr versus stdout.
* More diagnostics should an X error occur.
* Fixed a possible crash in SGI-specific unfading code.
Changes since 2.26: * Improved version of `distort'.
* Made `lament' compile against OpenGL 1.0 (though it
still requires 1.1 to work properly.)
* Updated my email address and home page.
Changes since 2.24: * Improved motion in `rd-bomb'.
* Added XSHM (shared memory extension) support to the
`distort', `interference', `moire', `rd-bomb', and
`swirl' hacks, which speeds them up a bit.
* Added `lament' hack.
Changes since 2.23: * Tweaked the order of the -L options again.
* Cleaned up configure's `--help' message.
* Added `kumppa' hack.
* Smarter maze-solving algorithm in `maze'.
* Took `xlyap' out of the default list of hacks, since
it's just incredibly buggy (and slow.) Maybe someday
someone will fix it...
* Added `distort' hack, but didn't add it to the default
list (yet) because it's still too slow.
* Made the Athena demo dialog look more like the Motif
version; it has a text-entry field now, too.
* Made the Athena password dialog echo asterisks, like
Motif does, instead of using a flyspeck font.
* Some random configure tweaks.
* Added a `timestamp' resource that makes the `-verbose'
messages include the time at which they were printed.
Changes since 2.22: * The fix for SGI's ``scheme'' nonsense broke things, and
let the user's "*background" resource show through.
Fixed it in a different way.
Changes since 2.21: * Added support for the DPMS server extension (Display
Power Management System.)
* Made configure advertize the `--enable-subdir' option a
little more, since that seemed to cause some people
stress. Also, made that directory be built into the
xscreensaver executable, as a hardcoded prefix to
$PATH. (Might help, shouldn't hurt.)
* Made configure prefer the two-arg gettimeofday to the
one-arg version, since AIX doesn't have any prototypes.
* Made it work with Xaw3d (the 3D Athena library.)
* Made `make install' create directories as necessary.
* New version of lmorph from Sverre.
* Added `crystal' and `discreet' hacks from xlockmore.
* Added a new mode to `bsod'.
Changes since 2.20: * Made `xscreensaver-command -time' use different words.
(It now describes the two states as "screen blanked
since..." and "screen non-blanked since..." instead of
"active since..." and "inactive since..." which a lot
of people interpreted as meaning the opposite of what
was intended.)
* Improved some error messages, in the hopes of making
the distinction between the xscreensaver and
xscreensaver-command programs more obvious.
* Rewrote (a
