13 ===============================================================================
15 This is the XScreenSaver source code distribution. It is strongly recommended
16 that you install a binary release rather than trying to compile it yourself.
17 Binaries are available for almost all platforms, including MacOS X. See the
18 XScreenSaver web site for details.
20 To compile on a Unix system with X11:
26 To compile on MacOS X:
28 Use the included XCode project. Requires XCode 2.4 and MacOS X 10.4.0

37 XScreenSaver has an extensive manual -- please read it!
39 ===============================================================================
41 Changes since 5.04: * New hacks, `cubicgrid', `hypnowheel', and
42 `lcdscrub' (which isn't really a screen saver).
43 * Updates to `m6502' and `gears'.
44 * Fixed double-buffering problems in `cubestorm' and
46 * Better handling of horizontal scroll wheels.
47 * Attempt to work around latest Xinerama braindamage:
48 if the server reports overlapping screens, use the
49 largest non-overlapping rectangles available.
50 * Don't warning about receipt of bogus ClientMessages,
51 since Gnome's just never going to stop sending those.
52 * Worked around MacOS 10.5 perl bug that caused the
53 text-displaying hacks to fail on some systems.
54 * Hopefully fixed font-related System Preferences crashes
56 * The recent PAM changes broke the "Caps Lock" warning
57 in the password dialog, the failed login warnings, and
58 syslogging. Fixed all that.
59 Changes since 5.03: * Fixed a possible crash in the unlock dialog (more
60 fallout from the recent PAM changes...)
61 * New hacks, `moebiusgears', `abstractile', and
63 * Rewrote `gears' to use better (involute) gear models,
64 and to be more random.
65 * Minor updates to `cwaves', `voronoi', `deco',
66 `glcells', `rd-bomb', `fireworkx' and `webcollage'.
67 * `pong' can now display the current time as the score.
68 * `xmatrix -mode pipe' works better.
69 * Minor tweaks for compilation on MacOS 10.5.0.
70 Changes since 5.02: * New hacks, `cwaves', `glcells', `m6502', and `voronoi'.
71 * Minor fixes to `bsod'.
72 * Fixed possible crash with PAM USB-dongle auth.
73 * Updated `webcollage' to track recent Google Images
75 Changes since 5.01: * Reworked PAM code to support fingerprint readers, etc.
76 * Ported 'webcollage' to OSX.
77 * Added OSX 10.2 and 10.3 kernel panics to `bsod'.
78 * Fixed a Xinerama crash when changing the screen count.
79 * New blobbier `mirrorblob'.
80 * Minor updates to `lisa', `bsod', `ifs', `hypertorus',
81 `polytopes', `circuit', `endgame', `crackberg',
82 `flipflop', `flipscreen3d', `fliptext', and `carousel'.
83 * Enabled multi-threaded OpenGL on OSX.
84 Changes since 5.00: * Backed out recent locale-related changes, since they
85 broke far more things than they fixed.
86 * Fail gracefully with ridiculously small window sizes.
87 * `xflame' and `flag' ignore bitmap option on MacOS.
88 * `speedmine' prefs work on MacOS.
89 * Better explosions in `boxed'.
90 * More dynamic motion in `sproingies'.
91 * More options in `flipflop'.
92 * Minor updates to `topblock'.
93 * Various other minor fixes.
94 Changes since 4.24: * Ported to MacOS X! (10.4.0 or newer)
95 * API change: instead of providing a single screenhack()
96 function that does not return, screen savers using the
97 screenhack.h framework must now provide "init" and
98 "draw one frame" functions instead. All bundled savers
99 have been updated; third-party patches will need work.
100 * All image-loading happens asynchronously.
101 * xscreensaver-getimage-file caches the contents of the
102 image directory for a few hours, so consecutive runs
103 won't have to re-list the whole directory tree.
104 * New hacks, `topblock' and `glschool'.
105 * Removed `xteevee' (superceded by `xanalogtv').
106 * Added variable-sized puzzle pieces to `jigsaw'.
107 * Changes to the defaults and command-line options of
108 many hacks to make the .xml files more consistent.
109 * Reap zombies in `glslideshow' and `carousel'.
110 * `sonar' works without setuid on OSX (dgram icmp).
111 * `xmatrix -mode pipe' displays the text of a subprocess.
112 * `endgame' has higher resolution chess-piece models.
113 * `webcollage' takes a -directory option to get images
114 from a local directory.
115 * The RPM spec file no longer auto-restarts xscreensaver
116 when a new version is installed. Restart it manually.
117 Changes since 4.23: * New versions of `cube21', `glsnake', `celtic'.
118 * Backed out a DPMS-related patch that cause desktop
119 flickering with some X servers.
120 * Fixed startup crash in getgroups() when running setuid.
121 * Default to not displaying stderr on the saver window.
122 * Fixed bad free() in "Documentation" button.
123 * Don't try to run hacks that aren't installed.
124 * Minor fixes to various XML config files and man pages.
125 Changes since 4.22: * New hacks, `glhanoi', `cube21', `timetunnel',
126 `juggler3d', and `celtic'.
127 * New versions of `tangram', `webcollage', `hypertorus',
128 `polytopes', and `ripples'.
129 * `sonar' is now quiet about unresolvable hosts.
130 * Minor corrections to BASIC code in `apple2'.
131 * xscreensaver-demo now provides an RPM clue when none
132 of the hacks seem to be installed.
133 * Don't install `ant' by default, since there is some
134 Java tool of that name, which was causing confusion.
135 And also it's boring.
136 * Made screen grabbing work again on MacOS 10.4.2.
137 * No longer prints bogus warnings about ClientMessages
138 intended for the window manager.
139 * Ignore unprintable characters in passwd entry field.
140 * Fixed yet another cross-host-display image-loading
142 * `xscreensaver-command -watch' and `-time' now work
144 Changes since 4.21: * Fixed a bug in the new mouse-motion code that caused
145 the screen to never blank on multi-head non-Xinerama
147 * New hacks, `interaggregate', `antmaze', `tangram',
149 * Minor tweaks to `fiberlamp', `ifs', `slidescreen',
150 `zoom', `sonar', `fireworkx', `whirlwindwarp',
151 `bubble3d', and `rd-bomb'.
152 * Added motion blur to `blinkbox'.
153 * `bsod' now includes Longhorn's "RSOD", and OS/2.
154 * Fixed `-wireframe' usage in most hacks and man pages.
155 Changes since 4.20: * New hack: `fliptext'.
156 * Changed default configure installation directories:
157 /usr/bin/ for xscreensaver, etc.;
158 /usr/libexec/xscreensaver/ for hacks;
159 /usr/share/xscreensaver/config/ for xml files.
160 * All the text-manipulating screen savers can have their
161 text source configured via `xscreensaver-demo' now.
162 * xscreensaver.spec now builds three RPMs:
163 base (no hacks); extras (2d hacks); and gl-extras.
164 * Added `-program' and `-front' option to `gltext'.
165 * Added `-shells' to `molecule'.
166 * Fixed text-alpha glitch in `carousel'.
167 * New `pacman': the ghosts can be killed now.
168 * Fixed a bug in screen-grabbing GL hacks where images
169 would be tiled instead of scaled on machines that
170 can't do large textures.
171 * `webcollage' can hit Flickr now.
172 * New (rewritten) implementation of `ifs'.
173 * The unlock dialog can be made to have a "New Login"
174 button that will run `gdmflexiserver'. Experimental!
175 * Fixed non-ASCII display bug in `starwars'.
176 * Configure finds a default for imageDirectory.
177 * "xscreensaver-command -lock" now works even if
178 in "screensaver disabled" mode.
179 * If a bad password is typed while CapsLock is on, the
180 unlock dialog says "CapsLock?" instead of "Sorry".
181 * Mouse motion only counts as activity if the mouse moved
182 more than 10 pixels (so the screen won't unblank every
183 time you bump your desk.)
184 * New mode option "random-same": if you have multiple
185 monitors, this will run the *same* randomly chosen
186 hack on each screen, instead of different ones on each.
187 Changes since 4.19: * New hacks, `fiberlamp', `boing', `boxfit', and
189 * Rewrote `glslideshow' again: should be faster now.
190 * Sped up loading of images in GL programs.
191 * `starwars' uses texture-mapped fonts now.
192 * New `bsod' modes: tru64, hppa, and nvidia.
193 * Updates to `webcollage', `juggle', `pinion',
194 `fireworkx', `sonar', `extrusion', `substrate', and
196 Changes since 4.18: * New hacks, `substrate', `intermomentary', `fireworkx',
198 * New version of `flow'.
199 * Made /proc/interrupts work again on Linux 2.6.
200 * Made `analogtv' not hog the CPU.
201 * Made analogtv-based hacks work properly on PPC/ARM.
202 * Fixed a bad memory leak in `piecewise'.
203 * Minor updates to `sonar', `molecule', `glmatrix',
204 `galaxy', and `webcollage'.
205 * Removed support for GTK 1.x (everyone uses 2.x now.)
206 Changes since 4.17: * Oops, pay no attention to the man behind the curtain.
207 Changes since 4.16: * New hacks, `anemotaxis' and `memscroller'.
208 * Fixed a bad bug that caused `vidwhacker' to never die.
209 * Fixed normals and lighting in `polyhedra'.
210 * Don't reuse the window when changing hacks (to work
211 around bugs in some GL implementations.)
212 * Made `xscreensaver-getimage-file' skip thumbnail-sized
214 * Fixed endian problem in `barcode' on non-x86.
215 * Updates to `webcollage', `apple2', `fuzzyflakes',
216 `atunnel', and `pacman'.
217 * Timing tweaks to `bubble3d', `bouncingcow', `engine',
218 `gltext', `lavalite', `molecule', `spotlight',
219 `sballs', `boxed', `blinkbox', and `circuit'.
220 * Configure updates for Fedora core 2 / xorg 6.7.0.
221 * Compile without warnings under gcc 3.3.3.
222 * I give up: don't blank or lock the screen if we can't
223 get a keyboard grab. In that case, both choices are
225 Changes since 4.15: * New hacks, `polyhedra', `fuzzyflakes', `antinspect',
227 * Minor updates to `webcollage', `bsod', `endgame',
228 `antspotlight', `xmatrix', and `glmatrix'.
229 * Added support for the RANDR (Resize and Rotate)
230 extension to detect when the size of the desktop has
231 been changed while xscreensaver is already running.
232 * Possibly-futile attempt to work around "rdesktop"
234 * Made `xscreensaver-getimage -file' still work even if
235 imageDirectory is unset.
236 * Convert Latin1 to ASCII in `starwars' and `phosphor'
237 (since the GLUT font only has ASCII glyphs.)
238 * Fixed randomization in `noof'.
239 * Added "GetViewPortIsFullOfLies" preference to work
240 around longstanding XFree86 bug #421.
241 * Made `sonar' subnet pinging work properly on bigendian
242 machines (e.g., PPC.)
243 Changes since 4.14: * New hacks, `wormhole', `mismunch', `noof', and
245 * `phosphor' and `apple2' include vt100 emulators now:
246 this means you can do "phosphor -program top", or
247 can use either program as an xterm replacement:
248 "apple2 -text -fast -program 'xemacs -nw'".
249 * `analogtv' (and related) fill the screen better.
250 * The '-gradient' option works in `atlantis' now.
251 * Minor updates to `blinkbox', `queens', `endgame',
252 `glmatrix', `mirrorblob', `blocktube', and `molecule'.
253 * Integrated SuSE's "external passwd helper" support.
254 * Marginally better /tmp handling in various programs.
255 * Updated config defaults for xplanet 1.0.3.
257 Changes since 4.13: * New hacks, `fontglide', `apple2', `xanalogtv', `pong',
258 `gleidescope', `mirrorblob', and `blinkbox'.
259 * New version of `glsnake' (with many more models.)
260 * Another Windows crash in `bsod'; also HVX/GCOS6/TPS6.
261 * New version of `endgame'.
262 * Screen grabbing works on MacOS X.
263 * Various minor fixes.
264 Changes since 4.12: * On Xinerama systems, xscreensaver now runs one hack on
265 each monitor (just like in "real" multi-head mode)
266 instead of running one hack stretching across all the
267 screens. Note that for this to work with any 3rd party
268 screensavers, they must update their "vroot.h" file.
269 * `webcollage' and `vidwhacker' display images using
270 `xscreensaver-getimage' now.
271 * Added `ljlatest' script for use with `starwars' and
273 Changes since 4.11: * New GL hacks, `flipflop', `antspotlight', and
275 * Added VMS to `bsod'.
276 * Compile without warnings in "gcc -pedantic".
277 * Updates to `webcollage' and `queens'.
278 * Fixed a bug that could cause PAM to hang.
279 Changes since 4.10: * New hacks, `hypertorus', `cubestorm', `glknots',
280 `blocktube', and `glmatrix'.
281 * Updates to `cloudlife', `engine', `xmatrix', and
283 * Rewrote `glslideshow': it should work on somewhat
284 wimpier video cards now.
285 * Various portability tweaks.
286 Changes since 4.09: * New hacks, `cloudlife' and `klein'.
287 * Added Apple ][+, HPUX, and OS/390 sessions to BSOD.
288 * Added some Matrix Reloaded text to `xmatrix'.
289 * Updates to `webcollage', `eruption', `jigglypuff',
290 `metaballs', and `endgame'.
291 * Completely ignore the `memoryLimit' setting now,
292 since it was still causing people GL grief.
293 * Various minor fixes.
294 Changes since 4.08: * New hacks, `flyingtoasters', `bouncingcow',
295 `jigglypuff', and `glslideshow'.
296 * More models in `engine'.
297 * Rewrote `xscreensaver-getimage' to remove reliance on
298 external image loaders (xv, chbg, xloadimage, etc.)
299 and to reduce flicker when loading files.
300 * Made `gflux' and `flipscreen3d' be mouse-spinnable.
301 Changes since 4.07: * New hacks, `atunnels' and `piecewise'.
302 * Physics improvement in `fluidballs'.
303 * Various fixes for XDarwin systems (X11 on MacOS X.)
304 * Added -clock option to `barcode'.
305 * Minor fixes to `endgame', `flurry', `flipscreen3d',
307 Changes since 4.06: * New hacks, `flurry', `metaballs', `eruption',
308 `popsquares', and `barcode'.
309 * Minor updates to `maze' for high density mazes.
310 * Added double buffering to `fluidballs' and `whirlygig'.
311 * Bug fixes for running xscreensaver to a remote XFree86
312 display (which nobody would ever do...)
313 * Updated `webcollage' (faster Alta Vista searching.)
314 * Updated `glplanet' so the sun sets in the west.
315 * Updated `sproingies' with smooth, unsegmented surfaces.
316 * Fixed Perl version-sensitivity in
317 `xscreensaver-getimage-file'.
318 * Fixed GTK2 scrolling bug in `xscreensaver-demo'.
319 Changes since 4.05: * New hack, `glblur' (disabled by default, since it
320 requires fast OpenGL texture support.)
321 * New hack, `halftone'.
322 * Updates to `endgame', `queens', `bumps', `glplanet',
323 `engine', and `circuit'.
324 * New version of `menger' that uses far fewer polygons.
325 * Fixed minor bug in `critical' that could cause some
326 bogus X servers to crash.
327 * Better labels in `molecule': the labels now appear to
328 be attached to the atoms, instead of floating in front
330 * Fixed bug that could rarely cause GL hacks to fail to
331 double-buffer (causing intermittent flickering.)
332 * Fixed a relative-URL-parsing bug in `webcollage'.
333 * Fixed a bug that (sometimes) caused the window manager
334 close box to kill `xscreensaver-demo' with a crash
335 instead of a graceful exit.
336 * Updated xscreensaver.pam to the Red Hat 7.3 way.
337 * More Gnome2-related configure crap.
338 * Updated to latest `config.guess' and `config.sub'.
339 * Fixed occasional core dump in `distort'.
340 * Added a Linux fsck failure and kernel panic to `bsod'.
341 * Added MacOS X kernel panic to `bsod'.
342 * Fixed a bug in `bsod' (all bsod bugs are ironic.)
343 * Fixed a bug that caused `xscreensaver-gl-helper' to
344 print a nonsense visual ID with some versions of
345 `printf': this could cause GL programs to display
346 incorrectly (e.g., flickery.)
347 Changes since 4.04: * More `configure' tweaks to try and get things working
348 on systems that both Gtk 1.x and 2.x installed.
349 * New hack, `endgame'.
350 * Minor updates to `gltext'.
351 Changes since 4.03: * Support for GTK 2.x / GNOME 2.x.
352 * The `configure' script will now use `pkg-config' if
353 you have it, in preference to `gtk-config', etc.
354 * New hacks, `lavalite', `queens', and `anemone'.
355 * Minor updates to `spheremonics', `gltext', `xmatrix'.
356 * You can use the mouse to manually spin most of the GL
357 hacks now (when they are displaying in a window.)
358 * Fixed a bug in `webcollage' (due to recent Alta Vista
359 url changes) that was causing it to try and load
360 incorrect image URLs.
361 * Made `xscreensaver-getimage' use gdk_pixbuf if it is
362 available: this means that those hacks that load images
363 will no longer rely on "xv", "xloadimage", etc. This
364 will close a race condition that could sometimes cause
365 your desktop background to be changed; and also makes
366 it possible for those programs to operate on image
367 files when running in windowed mode.
368 * `webcollage' can now be used in conjunction with
369 `driftnet' to display images snooped from your local
370 ethernet instead of obtained from search engines.
371 * Added man pages for all the hacks that didn't have
373 Changes since 4.02: * New hack, `spheremonics'.
374 * Minor updates to `webcollage', `cage', `moebius',
375 `morph3d', `boxed', `circuit', and `helix'.
376 * `pulsar' and `extrusion' can now load texture JPEGs.
377 * `rubik' now does non-square cubes.
378 * `fluidballs' now does various sizes of balls.
379 * `menger' and `sierpinski3d' now also show polygon
381 * `molecule' displays real subscripts in the formulae.
382 * GTK internationalization/localization support.
383 * Better detection of the various versions of libxml.
384 * Upgraded to autoconf 2.53 (from 2.13.)
385 Changes since 4.01: * Plugged a few minor leaks in `xscreensaver' and
387 * New hacks, `cubenetic' and `fluidballs'.
389 * Fixed sphere projection error in `glplanet'; installed
390 a better image of earth.
391 * Added Win2K and MacOS 1 crashes to `bsod'.
392 * Put back previous (better) version of `forest' that
393 was accidentially downgraded in the last release.
394 * New version of `bumps'.
395 * Made FPS computation in GL hacks more efficient: it
396 will influence the results less, thus resulting in
397 higher (but more accurate) reported frame rates.
398 Changes since 4.00: * New hacks: `twang', `glsnake', `boxed', `sballs',
400 * New hacks `apollonian', `euler2d', `juggle',
401 `polyominoes' and `thornbird', from xlockmore.
402 * Merged recent xlockmore changes into `ant', `braid',
403 `demon', `discrete', `drift', `fadeplot', `forest',
404 `grav', `hopalong', `ifs', `laser', `lightning',
405 `lisa', `lissie', `loop', `mountain', `penrose',
406 `rotor', `sierpinski', `slip', `sphere', `spiral',
407 `strange', and `vines'.
408 * Fixed the `gltext' bug that sometimes caused
409 horizontal lines to vanish again. This time for sure.
410 * Sped up `webcollage' by adding a C helper program to
411 replace the PPM pipeline. It also pastes images
412 semi-transparently now.
413 * Added support for the gdk_pixbuf library: if this lib
414 is available, then `blitspin', `xflame', and `flag'
415 can load GIF, JPEG, and PNG images in addition to XPM
417 * Fixed a rare race condition where the desktop-grabbing
418 hacks could sometimes leave the screen wedged, if the
419 user moved the mouse exactly when they were grabbing
420 the screen image (it would un-wedge the next time the
421 saver timed out or was activated.)
422 * Fixed incorrect colors in the screen-grabbing GL hacks
423 (`gflux' and `flipscreen3d'.)
424 * Made SIGHUP restart the daemon process (though using
425 `xscreensaver-command -restart' is still the preferred
427 * Tweaks to `xspirograph'.
428 * Minor configure and portability tweaks.
429 Changes since 3.34: * Redesigned `xscreensaver-demo' GUI: it now includes
430 small-preview and per-hack configuration dialogs.
431 * Added three new modes of operation: `One Screen Saver',
432 `Blank Screen', and `Don't Blank' (in addition to the
433 historical `Random Screen Saver').
434 * Configure now defaults to installing the hacks in
435 <prefix>/lib/xscreensaver/ instead of <prefix>/bin/.
436 (Most distros already did it this way.)
437 * New GL hacks, `menger', `engine', `flipscreen3d'.
438 * Made `sierpinski3d' be more colorful.
439 * New versions of `xmatrix' and `nerverot'.
440 * Fixed a bug in `starwars' that made the font be drawn
441 with thin lines in -root mode.
442 * Fixed a bad colormap bug in `crystal' that could make
443 *subsequent* hacks malfunction!
444 * Made `gflux' able to grab screen images (`-mode grab').
445 * Updated `webcollage' for recent search engine changes.
446 * Removed most command-line options to `xscreensaver':
447 just edit the ~/.xscreensaver file instead.
448 * Improved behavior on multi-screen and Xinerama systems:
449 the mouse now stays on the screen where the user left
450 it, and the password and splash dialogs always appear
451 on the screen that has the mouse.
452 * Made the splash dialog use more Gtk-like colors;
453 made it have only two buttons, "Settings" and "Help".
454 * Made `sonar' understand `.ssh/known_hosts2' format
455 files, and be better about stripping out illegal
457 Changes since 3.33: * Turned `memoryLimit' off by default, sigh. Apparently
458 some versions of the GL libraries (appear to) allocate
459 hundreds of megs for every GL program, so `memoryLimit'
460 was causing GL programs to malfunction or crash on
462 * Improved fading on TrueColor XFree86 4.1.x systems.
463 * New GL hack, `circuit'.
464 * Added `fuzz' mode to `decayscreen'.
465 * New version of `whirlygig'.
466 * Added links to `xplanet' and `sphereEversion'.
467 * Fixed rare race condition that could make `sonar' hang.
468 * Fixed potential crash in `speedmine'.
469 * Made `xscreensaver-demo' not crash when imageDirectory
470 was set to a non-existent directory.
471 * Made `xscreensaver-getimage-video' invoke XawTV's
472 `streamer' program better.
473 * Made `phosphor' and `starwars' deal with CR, LF,
474 or CRLF line endings.
475 * Changes for Cygwin compilation environments.
476 * Made `sonar' compile on systems that can't ping.
477 * Configure changes for HPUX 10.20.
478 * Made PAM code work on Red Had 4.2 systems.
479 * Made `xscreensaver-command -deactivate' work when the
480 saver is not active: what that does is reset the idle
481 timer, as if keyboard input had been detected. This
482 was added for the benefit of people writing DVD-playing
483 software: they can now prevent the screensaver from
484 kicking in by sending a -deactivate message once a
485 minute while the movie is playing and not paused.
486 * Various minor portability tweaks.
487 Changes since 3.32: * New hacks, `speedmine' and `whirlygig'.
488 * Sped up `pyro', made the explosions look a bit better.
489 * Added better stars to `glplanet' and `starwars'.
490 * Many internal changes to `webcollage'.
491 * Some new options to `attraction'.
492 * Minor fix to `noseguy' to avoid un-erased pixels.
493 * Rewrote the screen-eraser effects so that they complete
494 in the same amount of time regardless of how slow
495 your X server is (some of them were glacial on servers
497 * Fixed a potential free memory reference that could
498 sometimes cause a crash at startup.
499 * Possibly fixed a problem that could cause the daemon
500 to crash with an X error. I was never able to
501 reproduce this problem, but I think I might have
502 figured out what caused it.
503 * Worked around a problem that caused PAM authentication
504 to fail on some Red Hat 7.x systems.
505 * Added a `memoryLimit' parameter that controls the
506 amount of memory a graphics hack may allocate: if they
507 try to allocate more than this, malloc() will fail
508 (and they will exit or (safely) crash, rather than
509 hogging memory.) Default is 50M.
510 * Made `gnome-help-browser' be the default way to display
511 man pages in `xscreensaver-demo', if running on a
513 Changes since 3.31: * The image-manipulating hacks (`slidescreen', etc.) can
514 now operate on randomly chosen image files from disk,
515 or on frames captured from the system's video input,
516 instead of (or in addition to) manipulating images of
518 * Rewrote `vidwhacker' to use the new image-grabbing
520 * Made fading work on TrueColor XFree86 4.x systems.
521 * Fixed a subtle rendering bug in `atlantis' (the fish
523 * Made `atlantis' have a texture simulating light
524 reflections from the surface of the ocean.
525 * Fixed up label placement in `molecule'.
526 * Better color bars in `xteevee'.
527 * Made `install-strip' not try to strip scripts.
528 Changes since 3.30: * Put in more sensible defaults for DPMS, and updated
529 the documentation to reflect the fact that all your
530 DPMS settings are now belong to xscreensaver.
531 * Fixed the `xscreensaver.spec' file so that `--force'
533 * New versions of `rotzoomer' and `nerverot'.
534 * Fixed an OSF/1 compilation problem in `molecule'.
535 Changes since 3.29: * New hacks, `molecule', `dangerball', and `rotzoomer'.
536 * New version of `gflux'.
537 * Made `gltext' able to display the current time.
538 * Fixed a floating-point-precision problem in `gltext'
539 that sometimes caused horizontal lines to vanish.
540 * Removed the `-window-id' option from the hacks:
541 it never worked right, and was unnecessary.
542 * Made the `starwars' hack use thicker lines, antialias
543 the text, and fade out at the far edge instead of just
545 * Fixed an SHM segment leak in `moire'.
546 Changes since 3.28: * Better rendering of the new logo.
547 * New hack, `gltext'.
548 * Added `-planetary' option to `gears', to draw a
549 different kind of gear system.
550 * Made motion and rotation be smoother in `gears',
551 `glplanet', `moebius', `rubik', and `sierpinski3d'.
552 * Improved coloration in `sierpinski3d'.
553 * Made the GL hacks react to window size changes.
554 * Made most of the GL hacks take a -fps option (like
555 `pulsar' did), so you can use them to benchmark your
557 * Fixed the previous fix to `sonar'.
558 * Minor fix to `nerverot'.
559 Made sonar able to ping hosts on DEC OSF1.
560 * Eliminated a bogus "didn't get enough colors" warning
561 in some of the hacks.
562 Changes since 3.27: * New logo for xscreensaver!
563 * New hacks, `starwars' and `stonerview'.
564 * Made the motion of the bouncing ball in `stairs' be a
566 * Made newly-added screenhacks be added to .xscreensaver
567 automatically: if there are hacks in the app-defaults
568 file that are not also in ~/.xscreensaver, they will
569 be added to the end of the list.
570 * Redid the `Screensaver Options' part of the control
571 panel; xscreensaver now lets you configure your DPMS
573 * Fixed some Makefile problems with non-GL builds.
574 * Fixed detection of MesaGL for version 3.3.
575 * Better workaround to Red Hat 7.0's broken gcc.
576 * Added Sparc Solaris kernel panic to `bsod'.
577 Changes since 3.26: * New hacks: `zoom' and `whirlwindwarp'.
578 * Fixed a free-memory-reference bug in `sonar'.
579 * Better error handling when there are no suitable GL
581 * Added diagnostic dialog when xscreensaver-demo is
582 unable to launch xscreensaver (e.g., when running as
584 * Fixed a bug that caused screenhack argument changes
585 to be ignored when xscreensaver-demo was running as
586 root (if "root" and "nobody" have different home
588 * Made the programs default to ":0" if $DISPLAY is unset.
589 * Made the `-verbose' output include information about
590 which server extensions were supported at compile time.
591 * Worked around Red Hat 7.0's broken gcc 2.96.
592 * Updated default delays on the GL hacks to look better
593 on machines with super-fast 3D hardware.
594 * Install `screensaver-properties-capplet' to work around
595 the usual egregious GNOME lossage.
596 Changes since 3.25: * Added "enabled" checkboxes in the list of hacks in
597 xscreensaver-demo (Gtk version only.)
598 * New hacks `hyperball', `xrayswarm', and `gflux'.
599 * New versions of `nerverot', `galaxy', and `hypercube'.
600 * Small fixes to `phosphor', `shadebobs', `xflame',
602 * Added external helper program `xscreensaver-gl-helper'
603 to figure out which X visual to use for OpenGL
605 * Configure updates for XFree86 4.0, and for BSD.
606 * Made it be more tolerant of bogus /etc/group files.
607 * When installing the PAM config file, first try to just
608 copy an existing "xdm" or "login" config file, so that
609 xscreensaver does authentication in the same way as the
611 Changes since 3.24: * New hack, `nerverot'.
612 * Added BSD kernel panic to `bsod'.
613 * New version of `shadebobs'.
614 * New version of `petri'.
615 * Updated `webcollage' to handle recent Altavista URL
616 format changes; made it search the AP photo gallery.
617 * Revamped command-line options of `sonar' and made it
618 properly handle subnets.
619 * The `bubbles' hack can now trickle up or down the
621 * The `xsublim' hack can now read its text from programs.
622 * Support for GLE version 3 in `extrusion'.
623 * Fixed compilation problems in `maze'.
624 * Fixed a rare crash in `flow'.
625 * Fixes for minor installation problems.
626 Changes since 3.23: * Added `-ignorant' option to `maze' hack.
627 * Updates to `critical', `bsod', `xflame', and `flow'.
628 * Added support for Kerberos 5 (via its Kerberos 4
629 compatibility layer.)
630 * Fixed a bad leak in `xteevee'.
631 * Updated `webcollage' to handle recent Altavista URL
633 * Removed xscreensaver-demo's `Ok' and `Cancel' buttons,
634 since they were confusing people: all changes are now
636 * Made xscreensaver-demo install itself into the Gnome
638 Changes since 3.22: * Fixed some misplaced text fields in the Motif version
639 of xscreensaver-demo; fixed a crash in the Gtk version
640 that would happen if the programs list was empty.
641 * Fixed a recently-introduced bug in `pulsar'.
642 * Made `sierpinski3d' use solid tetrahedrons instead of
644 * Added `-trace' option to `xmatrix'.
645 * Added new hacks `xteevee' and `xspirograph'.
646 Changes since 3.21: * Fixed some bugs in xscreensaver-demo.
647 * Rewrote the Motif version of xscreensaver-demo to
648 match the new Gtk version.
649 * The Athena toolkit is no longer supported.
650 Changes since 3.20: * Tweaked the xscreensaver-demo UI (Gtk only.)
651 * Fixed a few visual selection bugs. I think the proper
652 GL visual should be used with nVidia systems now.
653 * Made the Makefiles obey $install_prefix.
654 * Made the `xscreensaver.spec' file able to generate both
655 GL and non-GL packages simultaneously.
656 Changes since 3.19: * Added new hacks `ripples' and `sierpinski3d'.
657 * Made `xscreensaver-command -exit' be silent when no
658 screen saver was running (instead of complaining.)
659 * Made `webcollage' and `vidwhacker' use `xloadimage'
660 when available (in addition to `xli' and `xv'.)
661 * Improved memory usage in `petri' and gave it a hard
662 cap on how much memory it can allocate.
663 * Added `-watch' option to `xscreensaver-command'.
664 * Made `xscreensaver-demo' come up with the
665 most-recently-run hack selected by default.
666 * Rewrote the Gtk version of `xscreensaver-demo'.
667 It's a lot easier to use now.
668 * Extended the format of the programs list in the
669 .xscreensaver file, for the benefit of the new
670 capabilities of `xscreensaver-demo'.
671 NOTE: you might want to delete your ~/.xscreensaver
672 file and allow it to be re-created! The old one
673 should still work, but xscreensaver-demo won't be as
675 Changes since 3.18: * Fixed gcc dependencies in `bumps' and `ccurve'.
676 * New hack, `extrusion'.
677 * Some of the web sites that `webcollage' was using as
678 its sources changed formats; tweaked it to understand
680 * Added typeahead in the password dialog: if the screen
681 is locked, and you unlock it by typing a character,
682 that key will be automatically inserted in the
683 password dialog (unless it is Return, Enter, Space,
684 or a non-printing key like Shift.)
685 * Made `xmatrix' take a `-small' option, since some
686 folks with tiny screens prefer a smaller font.
687 Changes since 3.17: * New versions of `shadebobs', `lmorph', and `distort'.
688 * Added `ccurve', `blaster', and `bumps' hacks.
689 * Replaced `forest' hack with a rewritten version.
690 * Worked around a Xinerama server bug.
691 * Fixed a bug I introduced in 3.10 that caused some
692 hacks to print out superfluous warnings about not
693 having gotten enough colors.
694 * Made `sproingies' obey the `-delay' option.
695 * Fixed a portability bug in `shadebobs'.
696 * Made `webcollage' and `vidwhacker' use `xli' in
697 preference to `xv', if it is available.
698 * Added a new source of images to `webcollage'.
699 * If running under KDE, xscreensaver will add itself to
700 KDE's list of screensavers (via xscreensaver.kss.)
701 * Improved detection of GL libraries.
702 * Made the password dialog include the date and time.
703 Changes since 3.16: * New version of `webcollage' -- deals better with
704 corrupted images, and can use an http proxy.
705 * New hack, `xsublim' (run it in the background,
706 rather than adding it to the programs list.)
707 * The xscreensaver daemon was leaking a file descriptor
708 each time you edited your .xscreensaver file. Fixed.
709 Changes since 3.15: * New version of `shadebobs'.
710 * Improved image selection in `webcollage', and sped it
712 * Made configure find the right version of perl.
713 * Rewrote the CGI part of `webcollage'.
714 * `make clean' was deleting some things it shouldn't.
715 * Fixed a typo in the default programs list.
716 Changes since 3.14: * Added `webcollage' and `shadebobs' hacks.
717 * Added a `-stdout' arg to `vidwhacker' so that it can
718 be used in a pipeline.
719 * Made `petri' use less memory.
720 Changes since 3.13: * Various improvements to the Gtk port.
721 * Turned off PAM by default on Solaris, since PAM seems
722 generally to be misconfigured out-of-the-box.
723 * Made the `--without-gtk' configure option work.
724 * Made configure check the Gtk version number, since it
726 * Fixed a bug in the code that attempted to prevent
727 changes of screen resolution while the screen is
729 * Fixed a race condition in `xscreensaver-demo' that
730 could cause an X error at startup.
731 * Added `-transparent' option to `deluxe'.
732 * Added `petri' hack.
733 Changes since 3.12: * Ported `xscreensaver-demo' to Gtk.
734 * Made it possible to build Motif, Gtk, and Athena
735 versions of `xscreensaver-demo' in the same directory
736 without reconfiguring.
737 * Made `xscreensaver-demo' chase symlinks before writing
738 the .xscreensaver file, so that if .xscreensaver is
739 itself a symlink, the underlying file will be replaced
741 * Some Makefile and configure tweaks for Solaris and
743 * Made it possible to set the fire color in `xflame'.
744 * Made transparency work in TrueColor (for `goop' and
746 * Fixed a multi-head bug introduced by the virtual
748 Changes since 3.11: * Made it so that you can't scroll the screen while the
749 lock dialog is up (with XFree86 virtual viewports.)
750 * Fixed a bug in `flag' that caused bob's chin to get cut
751 off after a few iterations.
752 Changes since 3.10: * Made `xjack' be black-on-white-ish, so that it looks
753 less like a computer screen and more like the
754 typewritten paper it's supposed to be.
755 * New version of `pulsar'.
756 * Fixed Solaris compilation problem in `phosphor'.
757 * Made xscreensaver notice XFree86's virtual root window
758 hack, so that if the X server's root window is larger
759 than the monitor's displayable resolution, the screen
760 saver will limit itself to the area that actually
761 appears on the screen.
762 * Made the xscreensaver daemon do a better job of
763 picking the visual class that should be used for GL
764 programs. Less user intervention should be needed
765 now: you can use the logical visual name `GL' instead
766 of having to figure out by hand which one to use.
767 * Oops, the visual was defaulting to "best" instead of
768 "default", because the .xscreensaver file was not being
769 loaded quite early enough.
770 * Made configure figure out how to build icmp ping
771 support into the `sonar' hack automatically.
772 * Made warnings about not being able to read shadow
773 passwords not be printed if compiled with PAM support.
774 * Improved PAM startup diagnostics.
775 * Worked around the Solaris PAM bug that was causing
776 crashes there, so now PAM is turned on by default.
777 * Made configure detect the number of arguments that
778 pam_strerror() takes, since on Linux, this apparently
779 changed between 2.0 and 2.2, sigh.
780 * Made the /proc/interrupts kludge look for "PS/2 Mouse"
781 as well as "keyboard".
782 * Made xscreensaver notice when there has been a sudden
783 large jump in wall-clock time, and if so, lock right
784 away, instead of waiting for "lockTimeout" to expire
785 first. (Laptops need this for safer recovery from
787 * Added `-throttle' option to `xscreensaver-command'.
788 Changes since 3.09: * Added `phosphor', `xmatrix', and `pulsar' hacks.
789 * Fixed a bug in the color allocator that sometimes
790 caused `starfish' to fall back to monochrome.
791 * Reduced the amount of code that runs before root
792 privileges are disavowed: "normal" and "shadow"
793 passwords now do some initialization as root, but the
794 PAM and Kerberos authorization schemes will be
795 initialized while running as "nobody". Supposedly
796 this closes a potential security hole when using
798 * Added some more sanity checking to configure.
799 Changes since 3.08: * Added `compass', `squiral', `xflame', `wander',
800 `spotlight', and `critical' hacks.
801 * Added some new modes to `decayscreen'.
802 * Made `deluxe' work in monochrome.
803 * Generalized usage of the Double-Buffer server extension
804 in several hacks (`compass', `deluxe', `interference',
805 `kumppa', and `moire2'.)
806 * Fixed another visual-depth problem in `rd-bomb'.
807 * The screen saver will now defer blanking if neither
808 the keyboard nor the mouse could be grabbed. Instead,
809 it will just try again in a few minutes. This fixes
810 a bad interaction between xscreensaver and programs
811 like VMware that hold the mouse and keyboard grabbed
813 * Added a new erase mode (expanding spiral.)
814 Changes since 3.07: * Fixed some bugs in my port of `t3d'.
815 * Added `penetrate' and `deluxe' hacks.
816 * When linking against Motif 2.x, also link against XPM.
817 * Added support for using /proc/interrupts for idle
818 detection on Linux. Now xscreensaver shouldn't kick
819 in when the user is active on a non-X virtual console.
820 * Upgraded to autoconf 2.13.
821 Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
822 in properly; check for _Xsetlocale in -lXintl.)
823 * Portability fixes for sonar.c.
824 * Fixed a compilation problem when you have GL but don't
826 * Made configure notice when MesaGL requires -lpthread.
827 * Made `flame' ignore SIGFPE (not sure if this is the
828 right fix; it seems only to be needed on FreeBSD.)
829 * Kludged `rd-bomb' work on visuals that are of depth 24
830 but that *do not* support pixmaps of depth 32.
831 * Fixed `halo' to work properly in TrueColor.
832 * Changed `xscreensaver.spec' to install the hacks in
833 /usr/X11R6/lib/xscreensaver/ by default, since that's
834 where recent Red Hat distributions put them.
836 * Updated versions of `crystal', `hopalong', and `flow'
838 * Imported `demon' and `loop' modes from xlockmore.
839 Changes since 3.05: * Oops, the "default-n" visual descriptor was broken;
840 it was always installing a colormap if the
841 `installColormap' preference was set, meaning that
842 `xearth', `xv' and friends were using the wrong
843 colors on 8-bit systems.
844 * Turned off HAVE_PING in `sonar', since it compiles
845 on some Linux systems, but not others of similar
847 Changes since 3.04: * Fixed an off-by-1 in `distort'.
848 * Added `sonar' hack.
849 * New version of `glplanet' (with stars.)
850 * Made all hacks exit when you type `q' or `ESC' at them,
851 and made them obey the WM_DELETE_WINDOW ClientMessage.
852 * Fixed a nonfatal buffer overrun in lament (note:
853 lament still doesn't work with MesaGL 3.0: it dies in
854 lambda_textured_triangle1(), which is Mesa's bug, not
856 Changes since 3.03: * Added an `xscreensaver.spec' file, to make it easier
857 for other folks to generate RPMs.
858 * Made the password code work on HPUX in the situation
859 where: ``enhanced security'' is available; but not
860 used; but the user typed a password more than 8
861 characters long anyway. FTSOHPUX.
862 Changes since 3.02: * Made locking work when passwd aging is enabled.
863 * Added support for PAM (Pluggable Authentication
864 Modules.) It is still turned off by default, though,
865 since it doesn't seem to work on Solaris 2.6, and has
866 been behaving erratically on Red Hat 5.1.
867 * Made each possible authentication method be tried in
868 turn until one succeeds; this means that Kerberos is
869 being used, we will first check Kerberos, and if that
870 fails, will then consult the local password file.
872 * Save and restore the bits under the passwd dialog,
873 to avoid leaving a black rectangle behind when
874 unlocking is cancelled.
875 Changes since 3.01: * Not everyone has sys/select.h, sigh...
876 Changes since 3.00: * Some fixes to `reflect'.
878 * Made it log unsuccessful attempts to unlock the screen
880 * Fixed a bug where `xscreensaver-demo' could be seeing
881 a different programs list than `xscreensaver' did.
882 Changes since 2.34: * The xscreensaver daemon no longer links against Motif
883 or Athena: demo-mode and the preferences panel are no
884 longer built in to the daemon, but are now handled by
885 an external program, `xscreensaver-demo'.
886 (I decided that this, along with the recent addition
887 of the `.xscreensaver' config file, justified bumping
888 the version number to 3.00, since this is a fairly
889 major architectural change.)
890 * Lines in the `*programs' resource may now begin with
891 the character "-", meaning "don't run this hack."
892 In this way, it's possible to disable a hack without
893 throwing away the information about it (making it
894 easier to change your mind later.) Eventually the
895 preferences/demo mode GUI should represent this as a
896 checkbox or something.
897 * Fixed a short race condition where it was possible for
898 xscreensaver to die with a BadWindow error if it was
899 blanking the screen just as another window was being
901 * Made it possible to disable specific modes in `bsod'.
902 Changes since 2.33: * Fixed a bug that was making `pipes' generate way too
903 many valves. Made the viewpoint in `pipes' be selected
904 randomly instead of always being -10 degrees.
905 * Fixed a bug in the XSHM code, in the case where the
906 server supports the XSHM extension but is not the same
907 machine as the client.
908 * Made `rd-bomb' default to taking up the whole screen.
909 * Made it not try to do fading/unfading if no PseudoColor
911 * Initial attempt at supporting VT-locking (doesn't work
913 * Eliminated the `captureStdout' resource; now
914 `captureStderr' controls both streams.
915 * Added `-capture-stderr' and `-no-capture-stderr'
916 command-line arguments.
917 * Added `glplanet' hack.
918 * When a hack is selected with `xscreensaver-command
919 -select', that hack will be used until further notice
920 (until the saver turns off, or another activation
922 Changes since 2.32: * Made `xscreensaver-command' print error messages:
923 the xscreensaver daemon now responds to ClientMessage
924 events by writing a response message on a window
925 property, instead of just writing to its stderr.
926 * Made the ~/.xscreensaver file be automatically reloaded
927 when the file date changes.
928 * The password dialog and splash screen no longer depend
929 on Motif or Athena. This should clear up a number of
930 focus problems, and is the first step on the path
931 toward moving all of the Motif/Athena/whatever code
932 out of the xscreensaver daemon, and into external
934 * Don't complain about LessTif 0.86 any more, since the
935 new password dialog makes that problem go away.
936 * Configure tweaks for Irix 6.5, SunOS 5.something.
937 * New `-reflect' option to `distort'.
938 Changes since 2.31: * Added reading and writing of a ~/.xscreensaver file,
939 so that the Preferences panel can save its settings.
940 * New version of `rubik'.
941 * Added `-select N' argument to `xscreensaver-command'.
942 * Oops, left out some of the `bubbles3d' files...
943 Changes since 2.30: * The cursor was invisible in the password dialog. Fixed.
944 * Made configure warn against MesaGL 2.6.
945 * Fixed X error at startup when using non-default visual.
946 * New version of `crystal', `ant', and `atlantis' from
948 * New hack, `bubble3d'.
949 * Added some new modes to `bsod'.
950 Changes since 2.29: * Changed the order in which -lSM and -lICE are linked
951 to be after Motif instead of before (Lesstif on Irix
953 Changes since 2.28: * Work around a bash bug in configure.
954 * Tweaked HPUX paths again. FTSOHPUX.
955 * Made configure recommend against LessTif 0.86, due
956 to a bug in that version that causes a security hole
957 in the screen locking code. LessTif 0.87 will fix it.
958 * Made all of the `--with' options to `configure' accept
959 a directory option as well (so that --with-motif=/FOO
960 will add -I/FOO/include -L/FOO/lib). I believe this is
961 the Configure Party Line of how do to such things.
962 * Fixed a bug where the mouse was left un-grabbed
963 after the first time the graphics hack was changed
964 (simplified all of the mouse-grabbing logic.)
965 * Maybe possibly perhaps made `vidwhacker' really not
966 leave stray xv windows around. This time for sure.
967 * Added a new erase mode (random dots fizzling out.)
968 * Added `-prefs' argument to `xscreensaver-command',
969 that brings up the Preferences dialog directly (it
970 seems that nobody ever noticed the `Preferences' button
971 on the Demo Mode dialog, maybe this will help.)
972 * Added a splash screen. Turn it off with *splash:false.
973 Changes since 2.27: * Better macsbug text in `bsod'.
974 * New version of `distort' with many new modes.
975 * Plugged a leak in `coral'.
976 * Tweaked configure for HPUX.
977 * Removed some compiler warnings.
978 * More consistent usage of stderr versus stdout.
979 * More diagnostics should an X error occur.
980 * Fixed a possible crash in SGI-specific unfading code.
981 Changes since 2.26: * Improved version of `distort'.
982 * Made `lament' compile against OpenGL 1.0 (though it
983 still requires 1.1 to work properly.)
984 * Updated my email address and home page.
985 Changes since 2.24: * Improved motion in `rd-bomb'.
986 * Added XSHM (shared memory extension) support to the

989 * Added `lament' hack.
990 Changes since 2.23: * Tweaked the order of the -L options again.
991 * Cleaned up configure's `--help' message.
992 * Added `kumppa' hack.
993 * Smarter maze-solving algorithm in `maze'.
994 * Took `xlyap' out of the default list of hacks, since
995 it's just incredibly buggy (and slow.) Maybe someday
996 someone will fix it...
997 * Added `distort' hack, but didn't add it to the default
998 list (yet) because it's still too slow.
999 * Made the Athena demo dialog look more like the Motif
1000 version; it has a text-entry field now, too.
1001 * Made the Athena password dialog echo asterisks, like
1002 Motif does, instead of using a flyspeck font.
1003 * Some random configure tweaks.
1004 * Added a `timestamp' resource that makes the `-verbose'
1005 messages include the time at which they were printed.

1007 let the user's "*background" resource show through.
1008 Fixed it in a different way.
1009 Changes since 2.21: * Added support for the DPMS server extension (Display
1010 Power Management System.)
1011 * Made configure advertize the `--enable-subdir' option a
1012 little more, since that seemed to cause some people
1013 stress. Also, made that directory be built into the
1014 xscreensaver executable, as a hardcoded prefix to
1015 $PATH. (Might help, shouldn't hurt.)
1016 * Made configure prefer the two-arg gettimeofday to the
1017 one-arg version, since AIX doesn't have any prototypes.

1020 * New version of lmorph from Sverre.

1024 (It now describes the two states as "screen blanked
1025 since..." and "screen non-blanked since..." instead of
1026 "active since..." and "inactive since..." which a lot
1027 of people interpreted as meaning the opposite of what
1029 * Improved some error messages, in the hopes of making
1030 the distinction between the xscreensaver and
1031 xscreensaver-command programs more obvious.
1032 * Rewrote (and reorganized) parts of the xscreensaver and
1033 xscreensaver-command manual pages.
1034 * Renamed xscreensaver's `-lock' command-line option to
1035 be `-lock-mode', to avoid confusion with the `-lock'
1036 option to xscreensaver-command, which does a totally
1038 * Removed xscreensaver's `-demo' command-line option for
1039 a similar reason; use `xscreensaver-command -demo'
1041 * Disabled SGI's ``scheme'' nonsense in a better way than
1042 fully-qualifying the background colors in every single
1044 * Fixed some other minor cosmetic problems when *sgiMode
1046 * Fixed an X error in `bsod -root' (how ironic...)
1047 Changes since 2.19: * Fixed a bug that caused the mouse to sometimes not be
1048 grabbed properly (meaning the window manager menu could
1049 pop up over the demo-mode display.)
1050 * Fixed a bug that made the stderr output sometimes get
1052 * Fixed a bug that made the demo-mode scrollbar move too
1054 * Protected against a possible buffer overflow.

1061 * Added `interference' hack.
1062 * Added `truchet' hack.
1063 * Added `bsod' hack.
1064 * Added some new modes to `vidwhacker'.
1065 Changes since 2.16: * Added a -window-id argument to most hacks, so that they
1066 can draw on arbitrary externally-provided windows.
1067 * Synched with xlockmore 4.11a01.
1068 * Added `flow' hack.
1069 * Added `atlantis' GL hack.
1070 * Renamed `puzzle' hack to `jigsaw', since xlock already
1071 had a different mode called `puzzle'.
1072 * Made it self-configure properly when Motif 2.1.0 is
1073 being used (requires -lXp now, sigh...)
1074 Changes since 2.15: * Made `flag' able to do XPM images.
1075 * New look for the xscreensaver logo (`xroger').

1088 * Split `escher' into `cage' and `moebius', as per
1090 * Changed subprocess handling to use sigaction() instead
1091 of signal() if it's available (this is necessary for
1092 SCO but should work fine on other systems too.)
1093 * Various other tweaks.
1094 Changes since 2.13: * Better fix for the Motif drag-and-die lossage.
1095 * Put in some kludges to work around a LessTif bug.
1096 * XScreenSaver is known to work with LessTif 0.82 now.
1097 * Made fading work on high-end SGI video hardware.
1098 * Fixed another SGI-specific bug in screen grabbing;
1099 will the madness never cease?
1100 * Fixed another crash in `xlyap'.
1101 Changes since 2.12: * Made `decayscreen' do directions other than down.
1102 * Improved `puzzle'.
1103 * Fixed a crash in `xlyap'.
1104 * Added CDE info to the man page, removed `cde.txt'.
1105 * Configure tweaks for Zippy.
1106 * Turned off the signal handling in `bubbles' because
1107 it was sometimes failing to die.
1108 * Added `hacks/xscreensaver-sgigl.c' to make it possible
1109 to run SGI's ElectroPaint hack (/usr/demos/bin/ep)

1111 * Fixed a buffer overrun in the locking code that some
1112 wily, malicious cracker must have slipped in.

1117 * Added `puzzle' hack.
1118 * Added `xlyap' hack.
1119 * Added `default-n' as a visual name, so that one can
1120 have -install on by default, but turn it off for
1121 certain poorly-behaved hacks (like xv.)
1122 * Added support for grabbing frames of external video
1123 (on SGI) to the screen-grabbing hacks (decayscreen,
1124 slidescreen, slip, blitspin, and puzzle.)
1125 * Improved look of tiles in `slidescreen'; fixed its
1126 color allocation problem.
1127 Changes since 2.10: * Tweaked `blitspin', added it to the default list.
