penrose, rotor, sierpinski, slip, sphere, spiral,
strange, and vines.

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.

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.)

and per-hack configuration dialogs.

<prefix>/lib/xscreensaver/ instead of <prefix>/bin/. (Most distros
already did it this way.)

- Fixed a bug in starwars that made the font be drawn with thin
lines in -root mode.

- 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.
- 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
- Made xscreensaver-getimage-video invoke XawTV's streamer program
- Made phosphor and starwars deal with CR, LF, or CRLF line
- 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.
- 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.
- 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
- 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.
- 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
- New versions of rotzoomer and nerverot.
- Fixed an OSF/1 compilation problem in molecule.
- 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.
- Better rendering of the new logo.
- New hack, gltext.
- Added -planetary option to gears, to draw a different kind of
- 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
- New logo for xscreensaver!
- New hacks, starwars and stonerview.
- Made the motion of the bouncing ball in stairs be a little less
- 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
- 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.
- 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.
- 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.
- 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
- 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.
- Added -ignorant option to maze hack.
- Updates to critical, bsod, xflame, and flow.
- Added support for Kerberos 5 (via its Kerberos 4 compatibility
- 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.
- 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.
- Fixed some bugs in xscreensaver-demo.
- Rewrote the Motif version of xscreensaver-demo to match the new Gtk
- The Athena toolkit is no longer supported.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Added webcollage and shadebobs hacks.
- Added a -stdout arg to vidwhacker so that it can be used in a
- Made petri use less memory.
- 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.
- 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.
- 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
- 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
- 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,
- Made the /proc/interrupts kludge look for “PS/2 Mouse” as well as
- 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.
- 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.
- Added compass, squiral, xflame, wander, spotlight, and
- 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
- Added a new erase mode (expanding spiral.)
- 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.
- 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
- Imported demon and loop modes from xlockmore.
- 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...
- 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.)
- 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.
- 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.
- Not everyone has sys/select.h, sigh...
- 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.
- 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
- 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
- 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.
- 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
- 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
- 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.)
- 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
- 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.
- 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...
- 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.
- Changed the order in which -lSM and -lICE are linked to be after
Motif instead of before (Lesstif on Irix needs this.)
- 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
- 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
- Added a splash screen. Turn it off with *splash:false.
- 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.
- 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.
- 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.
- 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.
- The fix for SGI's “scheme” nonsense broke things, and let the
user's “*background” resource show through. Fixed it in a different
- Added support for the DPMS server extension (Display Power
- 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.
- 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
- Rewrote (and reorganized) parts of the xscreensaver and
xscreensaver-command manual pages.
- Renamed xscreensaver's -lock command-line option to be
-lock-mode, to avoid confusion with the -lock option to
xscreensaver-command, which does a totally different thing.
- Removed xscreensaver's -demo command-line option for a similar
reason; use xscreensaver-command -demo instead.
- Disabled SGI's “scheme” nonsense in a better way than
fully-qualifying the background colors in every single hack.
- Fixed some other minor cosmetic problems when *sgiMode is turned on.
- Fixed an X error in bsod -root (how ironic...)
- Fixed a bug that caused the mouse to sometimes not be grabbed
properly (meaning the window manager menu could pop up over the
- Fixed a bug that made the stderr output sometimes get printed twice.
- Fixed a bug that made the demo-mode scrollbar move too fast.
- Protected against a possible buffer overflow.
- Made vidwhacker not leave stray xv windows around.
- New version of ant so that Bagley doesn't calve.
- Make configure on AIX get XShm from the right library.
- One file was missing from the tar file.
- Oops, atlantis wasn't being built by default.
- Added epicycle hack.
- Added interference hack.
- Added truchet hack.
- Added bsod hack.
- Added some new modes to vidwhacker.
- Added a -window-id argument to most hacks, so that they can draw on
arbitrary externally-provided windows.
- Synched with xlockmore 4.11a01.
- Added flow hack.
- Added atlantis GL hack.
- Renamed puzzle hack to jigsaw, since xlock already had a
different mode called puzzle.
- Made it self-configure properly when Motif 2.1.0 is being used
(requires -lXp now, sigh...)
- Made flag able to do XPM images.
- New look for the xscreensaver logo (xroger).
- Fixed compilation error on Suns with adjunct passwords.

- Added cynosure hack.
- Added moire2 hack.
- Tweaked erase.c some more.
- Made unfading a bit smoother.
- Added vidwhacker hack (not installed by default.)
- Added stairs hack.
- Split escher into cage and moebius, as per xlockmore.
- Changed subprocess handling to use sigaction() instead of signal()
if it's available (this is necessary for SCO but should work fine on
other systems too.)
- Various other tweaks.
- Better fix for the Motif drag-and-die lossage.
- Put in some kludges to work around a LessTif bug.
- XScreenSaver is known to work with LessTif 0.82 now.
- Made fading work on high-end SGI video hardware.
- Fixed another SGI-specific bug in screen grabbing; will the madness
- Fixed another crash in xlyap.
- Made decayscreen do directions other than down.
- Improved puzzle.
- Fixed a crash in xlyap.
- Added CDE info to the man page, removed cde.txt.
- Configure tweaks for Zippy.
- Turned off the signal handling in bubbles because it was sometimes
failing to die.
- Added hacks/xscreensaver-sgigl.c to make it possible to run SGI's
ElectroPaint hack (/usr/demos/bin/ep) with xscreensaver. Finally!
- Fixed a buffer overrun in the locking code that some wily, malicious
cracker must have slipped in.
- Disabled Motif drag-and-drool in the dialog box buttons, since it's
broken in some old versions of Motif.
- Added README.debugging.
- Added puzzle hack.
- Added xlyap hack.
- Added default-n as a visual name, so that one can have -install on
by default, but turn it off for certain poorly-behaved hacks (like
- Added support for grabbing frames of external video (on SGI) to the
screen-grabbing hacks (decayscreen, slidescreen, slip, blitspin, and
- Improved look of tiles in slidescreen; fixed its color allocation
- Tweaked blitspin, added it to the default list.
- Added lissie, mountain, triangle, worm, rotor, and ant
- Updated sierpinski, galaxy, and lisa.
- Thickened the lines in braid and lmorph.
- Updated VMS makefiles.
- Renamed fract to vines.
- Added xjack hack.
- Made a few more hacks use erase.c, and added a few more wipe styles.
- Fixed compilation problem with Sun's version of OpenGL.
