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

992 Changes since 2.26: * Improved version of `distort'.
993 * Made `lament' compile against OpenGL 1.0 (though it
994 still requires 1.1 to work properly.)
995 * Updated my email address and home page.
996 Changes since 2.24: * Improved motion in `rd-bomb'.
997 * Added XSHM (shared memory extension) support to the

1002 * Cleaned up configure's `--help' message.
1003 * Added `kumppa' hack.
1004 * Smarter maze-solving algorithm in `maze'.
1005 * Took `xlyap' out of the default list of hacks, since
1006 it's just incredibly buggy (and slow.) Maybe someday
1007 someone will fix it...
1008 * Added `distort' hack, but didn't add it to the default
1009 list (yet) because it's still too slow.
1010 * Made the Athena demo dialog look more like the Motif
1011 version; it has a text-entry field now, too.
1012 * Made the Athena password dialog echo asterisks, like
1013 Motif does, instead of using a flyspeck font.
1014 * Some random configure tweaks.

1016 messages include the time at which they were printed.

1020 Changes since 2.21: * Added support for the DPMS server extension (Display
1021 Power Management System.)
1022 * Made configure advertize the `--enable-subdir' option a
1023 little more, since that seemed to cause some people
1024 stress. Also, made that directory be built into the
1025 xscreensaver executable, as a hardcoded prefix to
1026 $PATH. (Might help, shouldn't hurt.)
1027 * Made configure prefer the two-arg gettimeofday to the
1028 one-arg version, since AIX doesn't have any prototypes.

1031 * New version of lmorph from Sverre.

1035 (It now describes the two states as "screen blanked
1036 since..." and "screen non-blanked since..." instead of
1037 "active since..." and "inactive since..." which a lot
1038 of people interpreted as meaning the opposite of what
1040 * Improved some error messages, in the hopes of making
1041 the distinction between the xscreensaver and
1042 xscreensaver-command programs more obvious.
1043 * Rewrote (and reorganized) parts of the xscreensaver and
1044 xscreensaver-command manual pages.
1045 * Renamed xscreensaver's `-lock' command-line option to
1046 be `-lock-mode', to avoid confusion with the `-lock'
1047 option to xscreensaver-command, which does a totally
1049 * Removed xscreensaver's `-demo' command-line option for
1050 a similar reason; use `xscreensaver-command -demo'
1052 * Disabled SGI's ``scheme'' nonsense in a better way than
1053 fully-qualifying the background colors in every single
1055 * Fixed some other minor cosmetic problems when *sgiMode
1057 * Fixed an X error in `bsod -root' (how ironic...)
1058 Changes since 2.19: * Fixed a bug that caused the mouse to sometimes not be
1059 grabbed properly (meaning the window manager menu could
1060 pop up over the demo-mode display.)
1061 * Fixed a bug that made the stderr output sometimes get
1063 * Fixed a bug that made the demo-mode scrollbar move too
1065 * Protected against a possible buffer overflow.

1073 * Added `truchet' hack.
1074 * Added `bsod' hack.
1075 * Added some new modes to `vidwhacker'.
1076 Changes since 2.16: * Added a -window-id argument to most hacks, so that they
1077 can draw on arbitrary externally-provided windows.
1078 * Synched with xlockmore 4.11a01.
1079 * Added `flow' hack.
1080 * Added `atlantis' GL hack.
1081 * Renamed `puzzle' hack to `jigsaw', since xlock already
1082 had a different mode called `puzzle'.
1083 * Made it self-configure properly when Motif 2.1.0 is
1084 being used (requires -lXp now, sigh...)
1085 Changes since 2.15: * Made `flag' able to do XPM images.
1086 * New look for the xscreensaver logo (`xroger').

1099 * Split `escher' into `cage' and `moebius', as per
1101 * Changed subprocess handling to use sigaction() instead
1102 of signal() if it's available (this is necessary for
1103 SCO but should work fine on other systems too.)
1104 * Various other tweaks.
1105 Changes since 2.13: * Better fix for the Motif drag-and-die lossage.
1106 * Put in some kludges to work around a LessTif bug.
1107 * XScreenSaver is known to work with LessTif 0.82 now.
1108 * Made fading work on high-end SGI video hardware.
1109 * Fixed another SGI-specific bug in screen grabbing;

1112 Changes since 2.12: * Made `decayscreen' do directions other than down.
1113 * Improved `puzzle'.
1114 * Fixed a crash in `xlyap'.
1115 * Added CDE info to the man page, removed `cde.txt'.
1116 * Configure tweaks for Zippy.

1118 it was sometimes failing to die.
1119 * Added `hacks/xscreensaver-sgigl.c' to make it possible

1122 * Fixed a buffer overrun in the locking code that some
1123 wily, malicious cracker must have slipped in.

1128 * Added `puzzle' hack.
1129 * Added `xlyap' hack.
1130 * Added `default-n' as a visual name, so that one can
1131 have -install on by default, but turn it off for
1132 certain poorly-behaved hacks (like xv.)
1133 * Added support for grabbing frames of external video
1134 (on SGI) to the screen-grabbing hacks (decayscreen,
1135 slidescreen, slip, blitspin, and puzzle.)
1136 * Improved look of tiles in `slidescreen'; fixed its
1137 color allocation problem.
