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 3.1 and MacOS X 10.4.0

72 * Better seeding of the RNG.
73 Changes since 5.09: * Fixed some crashes and color problems on MacOS 10.6.

93 * Arrgh, more RANDR noise! Fixes this time for rotated
94 screens, and for systems where RANDR lies and says the
96 * When the password dialog has timed out or been
97 cancelled, don't pop it right back up a second time.
98 * Password timeouts/cancels don't count as
100 * Retired some of the older, less interesting savers:
101 say goodbye to `bubbles', `critical', `flag', `forest',
102 `glforestfire', `lmorph', `laser', `lightning', `lisa',
103 `lissie', `rotor', `sphere', `spiral', `t3d', `vines',
104 `whirlygig', and `worm'.

118 entering numbers that are out of range.
119 * Added "Reset to Defaults" button on X11.

123 * The `-fps' option now shows CPU load.
124 Changes since 5.05: * Xinerama/RANDR fixes: this time for sure. It should
125 now work to add/remove monitors or resize screens at
127 * New hack, `skytentacles'.
128 * New version of `gleidescope'.
129 * Added the `-log' option to the xscreensaver daemon,
130 since a truly shocking number of Linux users seem to
131 have no idea how to redirect output to a file.
132 * Added `-duration' arg to most image-loading hacks,
133 so that they pick a new image every few minutes.
134 * Added an ATM crash to BSOD.
135 Changes since 5.04: * New hacks, `cubicgrid', `hypnowheel', and
136 `lcdscrub' (which isn't really a screen saver).
137 * Updates to `m6502' and `gears'.
138 * Fixed double-buffering problems in `cubestorm' and
140 * Better handling of horizontal scroll wheels.
141 * Attempt to work around latest Xinerama braindamage:
142 if the server reports overlapping screens, use the

144 * Don't warning about receipt of bogus ClientMessages,
145 since Gnome's just never going to stop sending those.
146 * Worked around MacOS 10.5 perl bug that caused the
147 text-displaying hacks to fail on some systems.
148 * Hopefully fixed font-related System Preferences crashes
150 * The recent PAM changes broke the "Caps Lock" warning
151 in the password dialog, the failed login warnings, and
152 syslogging. Fixed all that.
153 Changes since 5.03: * Fixed a possible crash in the unlock dialog (more
154 fallout from the recent PAM changes...)
155 * New hacks, `moebiusgears', `abstractile', and
157 * Rewrote `gears' to use better (involute) gear models,
158 and to be more random.
159 * Minor updates to `cwaves', `voronoi', `deco',
160 `glcells', `rd-bomb', `fireworkx' and `webcollage'.
161 * `pong' can now display the current time as the score.
162 * `xmatrix -mode pipe' works better.

175 `polytopes', `circuit', `endgame', `crackberg',
176 `flipflop', `flipscreen3d', `fliptext', and `carousel'.
177 * Enabled multi-threaded OpenGL on MacOS.
178 Changes since 5.00: * Backed out recent locale-related changes, since they
179 broke far more things than they fixed.
180 * Fail gracefully with ridiculously small window sizes.
181 * `xflame' and `flag' ignore bitmap option on MacOS.
182 * `speedmine' prefs work on MacOS.
183 * Better explosions in `boxed'.
184 * More dynamic motion in `sproingies'.
185 * More options in `flipflop'.
186 * Minor updates to `topblock'.
187 * Various other minor fixes.
188 Changes since 4.24: * Ported to MacOS X! (10.4.0 or newer)
189 * API change: instead of providing a single screenhack()
190 function that does not return, screen savers using the
191 screenhack.h framework must now provide "init" and
192 "draw one frame" functions instead. All bundled savers
193 have been updated; third-party patches will need work.
194 * All image-loading happens asynchronously.
195 * xscreensaver-getimage-file caches the contents of the
196 image directory for a few hours, so consecutive runs
197 won't have to re-list the whole directory tree.
198 * New hacks, `topblock' and `glschool'.
199 * Removed `xteevee' (superceded by `xanalogtv').
200 * Added variable-sized puzzle pieces to `jigsaw'.
201 * Changes to the defaults and command-line options of
202 many hacks to make the .xml files more consistent.
203 * Reap zombies in `glslideshow' and `carousel'.
204 * `sonar' works without setuid on MacOS (dgram icmp).
205 * `xmatrix -mode pipe' displays the text of a subprocess.
206 * `endgame' has higher resolution chess-piece models.
207 * `webcollage' takes a -directory option to get images
208 from a local directory.
209 * The RPM spec file no longer auto-restarts xscreensaver
210 when a new version is installed. Restart it manually.
211 Changes since 4.23: * New versions of `cube21', `glsnake', `celtic'.
212 * Backed out a DPMS-related patch that cause desktop
213 flickering with some X servers.
214 * Fixed startup crash in getgroups() when running setuid.
215 * Default to not displaying stderr on the saver window.
216 * Fixed bad free() in "Documentation" button.
217 * Don't try to run hacks that aren't installed.
218 * Minor fixes to various XML config files and man pages.
219 Changes since 4.22: * New hacks, `glhanoi', `cube21', `timetunnel',
220 `juggler3d', and `celtic'.
221 * New versions of `tangram', `webcollage', `hypertorus',
222 `polytopes', and `ripples'.
223 * `sonar' is now quiet about unresolvable hosts.
224 * Minor corrections to BASIC code in `apple2'.
225 * xscreensaver-demo now provides an RPM clue when none
226 of the hacks seem to be installed.
227 * Don't install `ant' by default, since there is some
228 Java tool of that name, which was causing confusion.
229 And also it's boring.
230 * Made screen grabbing work again on MacOS 10.4.2.
231 * No longer prints bogus warnings about ClientMessages
232 intended for the window manager.
233 * Ignore unprintable characters in passwd entry field.
234 * Fixed yet another cross-host-display image-loading
236 * `xscreensaver-command -watch' and `-time' now work
238 Changes since 4.21: * Fixed a bug in the new mouse-motion code that caused
239 the screen to never blank on multi-head non-Xinerama
241 * New hacks, `interaggregate', `antmaze', `tangram',
243 * Minor tweaks to `fiberlamp', `ifs', `slidescreen',
244 `zoom', `sonar', `fireworkx', `whirlwindwarp',
245 `bubble3d', and `rd-bomb'.
246 * Added motion blur to `blinkbox'.
247 * `bsod' now includes Longhorn's "RSOD", and OS/2.
248 * Fixed `-wireframe' usage in most hacks and man pages.
249 Changes since 4.20: * New hack: `fliptext'.
250 * Changed default configure installation directories:
251 /usr/bin/ for xscreensaver, etc.;
252 /usr/libexec/xscreensaver/ for hacks;
253 /usr/share/xscreensaver/config/ for xml files.
254 * All the text-manipulating screen savers can have their
255 text source configured via `xscreensaver-demo' now.
256 * xscreensaver.spec now builds three RPMs:
257 base (no hacks); extras (2d hacks); and gl-extras.
258 * Added `-program' and `-front' option to `gltext'.
259 * Added `-shells' to `molecule'.
260 * Fixed text-alpha glitch in `carousel'.
261 * New `pacman': the ghosts can be killed now.
262 * Fixed a bug in screen-grabbing GL hacks where images
263 would be tiled instead of scaled on machines that
264 can't do large textures.
265 * `webcollage' can hit Flickr now.
266 * New (rewritten) implementation of `ifs'.
267 * The unlock dialog can be made to have a "New Login"
268 button that will run `gdmflexiserver'. Experimental!
269 * Fixed non-ASCII display bug in `starwars'.
270 * Configure finds a default for imageDirectory.
271 * "xscreensaver-command -lock" now works even if
272 in "screensaver disabled" mode.
273 * If a bad password is typed while CapsLock is on, the
274 unlock dialog says "CapsLock?" instead of "Sorry".
275 * Mouse motion only counts as activity if the mouse moved
276 more than 10 pixels (so the screen won't unblank every
277 time you bump your desk.)
278 * New mode option "random-same": if you have multiple
279 monitors, this will run the *same* randomly chosen
280 hack on each screen, instead of different ones on each.
281 Changes since 4.19: * New hacks, `fiberlamp', `boing', `boxfit', and
283 * Rewrote `glslideshow' again: should be faster now.
284 * Sped up loading of images in GL programs.
285 * `starwars' uses texture-mapped fonts now.
286 * New `bsod' modes: tru64, hppa, and nvidia.
287 * Updates to `webcollage', `juggle', `pinion',
288 `fireworkx', `sonar', `extrusion', `substrate', and
290 Changes since 4.18: * New hacks, `substrate', `intermomentary', `fireworkx',
292 * New version of `flow'.
293 * Made /proc/interrupts work again on Linux 2.6.
294 * Made `analogtv' not hog the CPU.
295 * Made analogtv-based hacks work properly on PPC/ARM.
296 * Fixed a bad memory leak in `piecewise'.
297 * Minor updates to `sonar', `molecule', `glmatrix',
298 `galaxy', and `webcollage'.
299 * Removed support for GTK 1.x (everyone uses 2.x now.)
300 Changes since 4.17: * Oops, pay no attention to the man behind the curtain.
301 Changes since 4.16: * New hacks, `anemotaxis' and `memscroller'.
302 * Fixed a bad bug that caused `vidwhacker' to never die.
303 * Fixed normals and lighting in `polyhedra'.
304 * Don't reuse the window when changing hacks (to work
305 around bugs in some GL implementations.)
306 * Made `xscreensaver-getimage-file' skip thumbnail-sized
308 * Fixed endian problem in `barcode' on non-x86.
309 * Updates to `webcollage', `apple2', `fuzzyflakes',
310 `atunnel', and `pacman'.
311 * Timing tweaks to `bubble3d', `bouncingcow', `engine',
312 `gltext', `lavalite', `molecule', `spotlight',
313 `sballs', `boxed', `blinkbox', and `circuit'.
314 * Configure updates for Fedora core 2 / xorg 6.7.0.
315 * Compile without warnings under gcc 3.3.3.
316 * I give up: don't blank or lock the screen if we can't
317 get a keyboard grab. In that case, both choices are
319 Changes since 4.15: * New hacks, `polyhedra', `fuzzyflakes', `antinspect',
321 * Minor updates to `webcollage', `bsod', `endgame',
322 `antspotlight', `xmatrix', and `glmatrix'.
323 * Added support for the RANDR (Resize and Rotate)
324 extension to detect when the size of the desktop has
325 been changed while xscreensaver is already running.
326 * Possibly-futile attempt to work around "rdesktop"
328 * Made `xscreensaver-getimage -file' still work even if
329 imageDirectory is unset.
330 * Convert Latin1 to ASCII in `starwars' and `phosphor'
331 (since the GLUT font only has ASCII glyphs.)
332 * Fixed randomization in `noof'.
333 * Added "GetViewPortIsFullOfLies" preference to work
334 around longstanding XFree86 bug #421.
335 * Made `sonar' subnet pinging work properly on bigendian
336 machines (e.g., PPC.)
337 Changes since 4.14: * New hacks, `wormhole', `mismunch', `noof', and
339 * `phosphor' and `apple2' include vt100 emulators now:
340 this means you can do "phosphor -program top", or
341 can use either program as an xterm replacement:
342 "apple2 -text -fast -program 'xemacs -nw'".
343 * `analogtv' (and related) fill the screen better.
344 * The '-gradient' option works in `atlantis' now.
345 * Minor updates to `blinkbox', `queens', `endgame',
346 `glmatrix', `mirrorblob', `blocktube', and `molecule'.
347 * Integrated SuSE's "external passwd helper" support.
348 * Marginally better /tmp handling in various programs.
349 * Updated config defaults for xplanet 1.0.3.
351 Changes since 4.13: * New hacks, `fontglide', `apple2', `xanalogtv', `pong',
352 `gleidescope', `mirrorblob', and `blinkbox'.
353 * New version of `glsnake' (with many more models.)
354 * Another Windows crash in `bsod'; also HVX/GCOS6/TPS6.
355 * New version of `endgame'.
356 * Screen grabbing works on MacOS X.
357 * Various minor fixes.
358 Changes since 4.12: * On Xinerama systems, xscreensaver now runs one hack on
359 each monitor (just like in "real" multi-head mode)
360 instead of running one hack stretching across all the
361 screens. Note that for this to work with any 3rd party
362 screensavers, they must update their "vroot.h" file.
363 * `webcollage' and `vidwhacker' display images using
364 `xscreensaver-getimage' now.
365 * Added `ljlatest' script for use with `starwars' and
367 Changes since 4.11: * New GL hacks, `flipflop', `antspotlight', and
369 * Added VMS to `bsod'.
370 * Compile without warnings in "gcc -pedantic".
371 * Updates to `webcollage' and `queens'.
372 * Fixed a bug that could cause PAM to hang.
373 Changes since 4.10: * New hacks, `hypertorus', `cubestorm', `glknots',
374 `blocktube', and `glmatrix'.
375 * Updates to `cloudlife', `engine', `xmatrix', and
377 * Rewrote `glslideshow': it should work on somewhat
378 wimpier video cards now.
379 * Various portability tweaks.
380 Changes since 4.09: * New hacks, `cloudlife' and `klein'.
381 * Added Apple ][+, HPUX, and OS/390 sessions to BSOD.
382 * Added some Matrix Reloaded text to `xmatrix'.
383 * Updates to `webcollage', `eruption', `jigglypuff',
384 `metaballs', and `endgame'.
385 * Completely ignore the `memoryLimit' setting now,
386 since it was still causing people GL grief.
387 * Various minor fixes.
388 Changes since 4.08: * New hacks, `flyingtoasters', `bouncingcow',
389 `jigglypuff', and `glslideshow'.
390 * More models in `engine'.
391 * Rewrote `xscreensaver-getimage' to remove reliance on
392 external image loaders (xv, chbg, xloadimage, etc.)
393 and to reduce flicker when loading files.
394 * Made `gflux' and `flipscreen3d' be mouse-spinnable.
395 Changes since 4.07: * New hacks, `atunnels' and `piecewise'.
396 * Physics improvement in `fluidballs'.
397 * Various fixes for XDarwin systems (X11 on MacOS X.)
398 * Added -clock option to `barcode'.
399 * Minor fixes to `endgame', `flurry', `flipscreen3d',
401 Changes since 4.06: * New hacks, `flurry', `metaballs', `eruption',
402 `popsquares', and `barcode'.
403 * Minor updates to `maze' for high density mazes.
404 * Added double buffering to `fluidballs' and `whirlygig'.
405 * Bug fixes for running xscreensaver to a remote XFree86
406 display (which nobody would ever do...)
407 * Updated `webcollage' (faster Alta Vista searching.)
408 * Updated `glplanet' so the sun sets in the west.
409 * Updated `sproingies' with smooth, unsegmented surfaces.
410 * Fixed Perl version-sensitivity in
411 `xscreensaver-getimage-file'.
412 * Fixed GTK2 scrolling bug in `xscreensaver-demo'.
413 Changes since 4.05: * New hack, `glblur' (disabled by default, since it
414 requires fast OpenGL texture support.)
415 * New hack, `halftone'.
416 * Updates to `endgame', `queens', `bumps', `glplanet',
417 `engine', and `circuit'.
418 * New version of `menger' that uses far fewer polygons.
419 * Fixed minor bug in `critical' that could cause some
420 bogus X servers to crash.
421 * Better labels in `molecule': the labels now appear to
422 be attached to the atoms, instead of floating in front
424 * Fixed bug that could rarely cause GL hacks to fail to
425 double-buffer (causing intermittent flickering.)
426 * Fixed a relative-URL-parsing bug in `webcollage'.
427 * Fixed a bug that (sometimes) caused the window manager
428 close box to kill `xscreensaver-demo' with a crash
429 instead of a graceful exit.
430 * Updated xscreensaver.pam to the Red Hat 7.3 way.
431 * More Gnome2-related configure crap.
432 * Updated to latest `config.guess' and `config.sub'.
433 * Fixed occasional core dump in `distort'.
434 * Added a Linux fsck failure and kernel panic to `bsod'.
435 * Added MacOS X kernel panic to `bsod'.
436 * Fixed a bug in `bsod' (all bsod bugs are ironic.)
437 * Fixed a bug that caused `xscreensaver-gl-helper' to
438 print a nonsense visual ID with some versions of
439 `printf': this could cause GL programs to display
440 incorrectly (e.g., flickery.)
441 Changes since 4.04: * More `configure' tweaks to try and get things working
442 on systems that both Gtk 1.x and 2.x installed.
443 * New hack, `endgame'.
444 * Minor updates to `gltext'.
445 Changes since 4.03: * Support for GTK 2.x / GNOME 2.x.
446 * The `configure' script will now use `pkg-config' if
447 you have it, in preference to `gtk-config', etc.
448 * New hacks, `lavalite', `queens', and `anemone'.
449 * Minor updates to `spheremonics', `gltext', `xmatrix'.
450 * You can use the mouse to manually spin most of the GL
451 hacks now (when they are displaying in a window.)
452 * Fixed a bug in `webcollage' (due to recent Alta Vista
453 url changes) that was causing it to try and load
454 incorrect image URLs.
455 * Made `xscreensaver-getimage' use gdk_pixbuf if it is
456 available: this means that those hacks that load images
457 will no longer rely on "xv", "xloadimage", etc. This
458 will close a race condition that could sometimes cause
459 your desktop background to be changed; and also makes
460 it possible for those programs to operate on image
461 files when running in windowed mode.
462 * `webcollage' can now be used in conjunction with
463 `driftnet' to display images snooped from your local
464 ethernet instead of obtained from search engines.
465 * Added man pages for all the hacks that didn't have
467 Changes since 4.02: * New hack, `spheremonics'.
468 * Minor updates to `webcollage', `cage', `moebius',
469 `morph3d', `boxed', `circuit', and `helix'.
470 * `pulsar' and `extrusion' can now load texture JPEGs.
471 * `rubik' now does non-square cubes.
472 * `fluidballs' now does various sizes of balls.
473 * `menger' and `sierpinski3d' now also show polygon
475 * `molecule' displays real subscripts in the formulae.
476 * GTK internationalization/localization support.
477 * Better detection of the various versions of libxml.
478 * Upgraded to autoconf 2.53 (from 2.13.)
479 Changes since 4.01: * Plugged a few minor leaks in `xscreensaver' and
481 * New hacks, `cubenetic' and `fluidballs'.
483 * Fixed sphere projection error in `glplanet'; installed
484 a better image of earth.
485 * Added Win2K and MacOS 1 crashes to `bsod'.
486 * Put back previous (better) version of `forest' that
487 was accidentially downgraded in the last release.
488 * New version of `bumps'.
489 * Made FPS computation in GL hacks more efficient: it
490 will influence the results less, thus resulting in
491 higher (but more accurate) reported frame rates.
492 Changes since 4.00: * New hacks: `twang', `glsnake', `boxed', `sballs',
494 * New hacks `apollonian', `euler2d', `juggle',
495 `polyominoes' and `thornbird', from xlockmore.
496 * Merged recent xlockmore changes into `ant', `braid',
497 `demon', `discrete', `drift', `fadeplot', `forest',
498 `grav', `hopalong', `ifs', `laser', `lightning',
499 `lisa', `lissie', `loop', `mountain', `penrose',
500 `rotor', `sierpinski', `slip', `sphere', `spiral',
501 `strange', and `vines'.
502 * Fixed the `gltext' bug that sometimes caused
503 horizontal lines to vanish again. This time for sure.
504 * Sped up `webcollage' by adding a C helper program to
505 replace the PPM pipeline. It also pastes images
506 semi-transparently now.
507 * Added support for the gdk_pixbuf library: if this lib
508 is available, then `blitspin', `xflame', and `flag'
509 can load GIF, JPEG, and PNG images in addition to XPM
511 * Fixed a rare race condition where the desktop-grabbing
512 hacks could sometimes leave the screen wedged, if the
513 user moved the mouse exactly when they were grabbing
514 the screen image (it would un-wedge the next time the
515 saver timed out or was activated.)
516 * Fixed incorrect colors in the screen-grabbing GL hacks
517 (`gflux' and `flipscreen3d'.)
518 * Made SIGHUP restart the daemon process (though using
519 `xscreensaver-command -restart' is still the preferred
521 * Tweaks to `xspirograph'.
522 * Minor configure and portability tweaks.
523 Changes since 3.34: * Redesigned `xscreensaver-demo' GUI: it now includes
524 small-preview and per-hack configuration dialogs.
525 * Added three new modes of operation: `One Screen Saver',
526 `Blank Screen', and `Don't Blank' (in addition to the
527 historical `Random Screen Saver').
528 * Configure now defaults to installing the hacks in
529 <prefix>/lib/xscreensaver/ instead of <prefix>/bin/.
530 (Most distros already did it this way.)
531 * New GL hacks, `menger', `engine', `flipscreen3d'.
532 * Made `sierpinski3d' be more colorful.
533 * New versions of `xmatrix' and `nerverot'.
534 * Fixed a bug in `starwars' that made the font be drawn
535 with thin lines in -root mode.
536 * Fixed a bad colormap bug in `crystal' that could make
537 *subsequent* hacks malfunction!
538 * Made `gflux' able to grab screen images (`-mode grab').
539 * Updated `webcollage' for recent search engine changes.
540 * Removed most command-line options to `xscreensaver':
541 just edit the ~/.xscreensaver file instead.
542 * Improved behavior on multi-screen and Xinerama systems:
543 the mouse now stays on the screen where the user left
544 it, and the password and splash dialogs always appear
545 on the screen that has the mouse.
546 * Made the splash dialog use more Gtk-like colors;
547 made it have only two buttons, "Settings" and "Help".
548 * Made `sonar' understand `.ssh/known_hosts2' format
549 files, and be better about stripping out illegal
551 Changes since 3.33: * Turned `memoryLimit' off by default, sigh. Apparently
552 some versions of the GL libraries (appear to) allocate
553 hundreds of megs for every GL program, so `memoryLimit'
554 was causing GL programs to malfunction or crash on
556 * Improved fading on TrueColor XFree86 4.1.x systems.
557 * New GL hack, `circuit'.
558 * Added `fuzz' mode to `decayscreen'.
559 * New version of `whirlygig'.
560 * Added links to `xplanet' and `sphereEversion'.
561 * Fixed rare race condition that could make `sonar' hang.
562 * Fixed potential crash in `speedmine'.
563 * Made `xscreensaver-demo' not crash when imageDirectory
564 was set to a non-existent directory.
565 * Made `xscreensaver-getimage-video' invoke XawTV's
566 `streamer' program better.
567 * Made `phosphor' and `starwars' deal with CR, LF,
568 or CRLF line endings.
569 * Changes for Cygwin compilation environments.
570 * Made `sonar' compile on systems that can't ping.
571 * Configure changes for HPUX 10.20.
572 * Made PAM code work on Red Had 4.2 systems.
573 * Made `xscreensaver-command -deactivate' work when the
574 saver is not active: what that does is reset the idle
575 timer, as if keyboard input had been detected. This
576 was added for the benefit of people writing DVD-playing
577 software: they can now prevent the screensaver from
578 kicking in by sending a -deactivate message once a
579 minute while the movie is playing and not paused.
580 * Various minor portability tweaks.
581 Changes since 3.32: * New hacks, `speedmine' and `whirlygig'.
582 * Sped up `pyro', made the explosions look a bit better.
583 * Added better stars to `glplanet' and `starwars'.
584 * Many internal changes to `webcollage'.
585 * Some new options to `attraction'.
586 * Minor fix to `noseguy' to avoid un-erased pixels.
587 * Rewrote the screen-eraser effects so that they complete
588 in the same amount of time regardless of how slow
589 your X server is (some of them were glacial on servers
591 * Fixed a potential free memory reference that could
592 sometimes cause a crash at startup.
593 * Possibly fixed a problem that could cause the daemon
594 to crash with an X error. I was never able to
595 reproduce this problem, but I think I might have
596 figured out what caused it.
597 * Worked around a problem that caused PAM authentication
598 to fail on some Red Hat 7.x systems.
599 * Added a `memoryLimit' parameter that controls the
600 amount of memory a graphics hack may allocate: if they
601 try to allocate more than this, malloc() will fail
602 (and they will exit or (safely) crash, rather than
603 hogging memory.) Default is 50M.
604 * Made `gnome-help-browser' be the default way to display
605 man pages in `xscreensaver-demo', if running on a
607 Changes since 3.31: * The image-manipulating hacks (`slidescreen', etc.) can
608 now operate on randomly chosen image files from disk,
609 or on frames captured from the system's video input,
610 instead of (or in addition to) manipulating images of
612 * Rewrote `vidwhacker' to use the new image-grabbing
614 * Made fading work on TrueColor XFree86 4.x systems.
615 * Fixed a subtle rendering bug in `atlantis' (the fish
617 * Made `atlantis' have a texture simulating light
618 reflections from the surface of the ocean.
619 * Fixed up label placement in `molecule'.
620 * Better color bars in `xteevee'.
621 * Made `install-strip' not try to strip scripts.
622 Changes since 3.30: * Put in more sensible defaults for DPMS, and updated
623 the documentation to reflect the fact that all your
624 DPMS settings are now belong to xscreensaver.
625 * Fixed the `xscreensaver.spec' file so that `--force'
627 * New versions of `rotzoomer' and `nerverot'.
628 * Fixed an OSF/1 compilation problem in `molecule'.
629 Changes since 3.29: * New hacks, `molecule', `dangerball', and `rotzoomer'.
630 * New version of `gflux'.
631 * Made `gltext' able to display the current time.
632 * Fixed a floating-point-precision problem in `gltext'
633 that sometimes caused horizontal lines to vanish.
634 * Removed the `-window-id' option from the hacks:
635 it never worked right, and was unnecessary.
636 * Made the `starwars' hack use thicker lines, antialias
637 the text, and fade out at the far edge instead of just
639 * Fixed an SHM segment leak in `moire'.
640 Changes since 3.28: * Better rendering of the new logo.
641 * New hack, `gltext'.
642 * Added `-planetary' option to `gears', to draw a
643 different kind of gear system.
644 * Made motion and rotation be smoother in `gears',
645 `glplanet', `moebius', `rubik', and `sierpinski3d'.
646 * Improved coloration in `sierpinski3d'.
647 * Made the GL hacks react to window size changes.
648 * Made most of the GL hacks take a -fps option (like
649 `pulsar' did), so you can use them to benchmark your
651 * Fixed the previous fix to `sonar'.
652 * Minor fix to `nerverot'.
653 Made sonar able to ping hosts on DEC OSF1.
654 * Eliminated a bogus "didn't get enough colors" warning
655 in some of the hacks.
656 Changes since 3.27: * New logo for xscreensaver!
657 * New hacks, `starwars' and `stonerview'.
658 * Made the motion of the bouncing ball in `stairs' be a
660 * Made newly-added screenhacks be added to .xscreensaver
661 automatically: if there are hacks in the app-defaults
662 file that are not also in ~/.xscreensaver, they will
663 be added to the end of the list.
664 * Redid the `Screensaver Options' part of the control
665 panel; xscreensaver now lets you configure your DPMS
667 * Fixed some Makefile problems with non-GL builds.
668 * Fixed detection of MesaGL for version 3.3.
669 * Better workaround to Red Hat 7.0's broken gcc.
670 * Added Sparc Solaris kernel panic to `bsod'.
671 Changes since 3.26: * New hacks: `zoom' and `whirlwindwarp'.
672 * Fixed a free-memory-reference bug in `sonar'.
673 * Better error handling when there are no suitable GL
675 * Added diagnostic dialog when xscreensaver-demo is
676 unable to launch xscreensaver (e.g., when running as
678 * Fixed a bug that caused screenhack argument changes
679 to be ignored when xscreensaver-demo was running as
680 root (if "root" and "nobody" have different home
682 * Made the programs default to ":0" if $DISPLAY is unset.
683 * Made the `-verbose' output include information about
684 which server extensions were supported at compile time.
685 * Worked around Red Hat 7.0's broken gcc 2.96.
686 * Updated default delays on the GL hacks to look better
687 on machines with super-fast 3D hardware.
688 * Install `screensaver-properties-capplet' to work around
689 the usual egregious GNOME lossage.
690 Changes since 3.25: * Added "enabled" checkboxes in the list of hacks in
691 xscreensaver-demo (Gtk version only.)
692 * New hacks `hyperball', `xrayswarm', and `gflux'.
693 * New versions of `nerverot', `galaxy', and `hypercube'.
694 * Small fixes to `phosphor', `shadebobs', `xflame',
696 * Added external helper program `xscreensaver-gl-helper'
697 to figure out which X visual to use for OpenGL
699 * Configure updates for XFree86 4.0, and for BSD.
700 * Made it be more tolerant of bogus /etc/group files.
701 * When installing the PAM config file, first try to just
702 copy an existing "xdm" or "login" config file, so that
703 xscreensaver does authentication in the same way as the
705 Changes since 3.24: * New hack, `nerverot'.
706 * Added BSD kernel panic to `bsod'.
707 * New version of `shadebobs'.
708 * New version of `petri'.
709 * Updated `webcollage' to handle recent Altavista URL
710 format changes; made it search the AP photo gallery.
711 * Revamped command-line options of `sonar' and made it
712 properly handle subnets.
713 * The `bubbles' hack can now trickle up or down the
715 * The `xsublim' hack can now read its text from programs.
716 * Support for GLE version 3 in `extrusion'.
717 * Fixed compilation problems in `maze'.
718 * Fixed a rare crash in `flow'.
719 * Fixes for minor installation problems.
720 Changes since 3.23: * Added `-ignorant' option to `maze' hack.
721 * Updates to `critical', `bsod', `xflame', and `flow'.
722 * Added support for Kerberos 5 (via its Kerberos 4
723 compatibility layer.)
724 * Fixed a bad leak in `xteevee'.
725 * Updated `webcollage' to handle recent Altavista URL
727 * Removed xscreensaver-demo's `Ok' and `Cancel' buttons,
728 since they were confusing people: all changes are now
730 * Made xscreensaver-demo install itself into the Gnome
732 Changes since 3.22: * Fixed some misplaced text fields in the Motif version
733 of xscreensaver-demo; fixed a crash in the Gtk version
734 that would happen if the programs list was empty.
735 * Fixed a recently-introduced bug in `pulsar'.
736 * Made `sierpinski3d' use solid tetrahedrons instead of
738 * Added `-trace' option to `xmatrix'.
739 * Added new hacks `xteevee' and `xspirograph'.
740 Changes since 3.21: * Fixed some bugs in xscreensaver-demo.
741 * Rewrote the Motif version of xscreensaver-demo to
742 match the new Gtk version.
743 * The Athena toolkit is no longer supported.
744 Changes since 3.20: * Tweaked the xscreensaver-demo UI (Gtk only.)
745 * Fixed a few visual selection bugs. I think the proper
746 GL visual should be used with nVidia systems now.
747 * Made the Makefiles obey $install_prefix.
748 * Made the `xscreensaver.spec' file able to generate both
749 GL and non-GL packages simultaneously.
750 Changes since 3.19: * Added new hacks `ripples' and `sierpinski3d'.
751 * Made `xscreensaver-command -exit' be silent when no
752 screen saver was running (instead of complaining.)
753 * Made `webcollage' and `vidwhacker' use `xloadimage'
754 when available (in addition to `xli' and `xv'.)
755 * Improved memory usage in `petri' and gave it a hard
756 cap on how much memory it can allocate.
757 * Added `-watch' option to `xscreensaver-command'.
758 * Made `xscreensaver-demo' come up with the
759 most-recently-run hack selected by default.
760 * Rewrote the Gtk version of `xscreensaver-demo'.
761 It's a lot easier to use now.
762 * Extended the format of the programs list in the
763 .xscreensaver file, for the benefit of the new
764 capabilities of `xscreensaver-demo'.
765 NOTE: you might want to delete your ~/.xscreensaver
766 file and allow it to be re-created! The old one
767 should still work, but xscreensaver-demo won't be as
769 Changes since 3.18: * Fixed gcc dependencies in `bumps' and `ccurve'.
770 * New hack, `extrusion'.
771 * Some of the web sites that `webcollage' was using as
772 its sources changed formats; tweaked it to understand
774 * Added typeahead in the password dialog: if the screen
775 is locked, and you unlock it by typing a character,
776 that key will be automatically inserted in the
777 password dialog (unless it is Return, Enter, Space,
778 or a non-printing key like Shift.)
779 * Made `xmatrix' take a `-small' option, since some
780 folks with tiny screens prefer a smaller font.
781 Changes since 3.17: * New versions of `shadebobs', `lmorph', and `distort'.
782 * Added `ccurve', `blaster', and `bumps' hacks.
783 * Replaced `forest' hack with a rewritten version.
784 * Worked around a Xinerama server bug.
785 * Fixed a bug I introduced in 3.10 that caused some
786 hacks to print out superfluous warnings about not
787 having gotten enough colors.
788 * Made `sproingies' obey the `-delay' option.
789 * Fixed a portability bug in `shadebobs'.
790 * Made `webcollage' and `vidwhacker' use `xli' in
791 preference to `xv', if it is available.
792 * Added a new source of images to `webcollage'.
793 * If running under KDE, xscreensaver will add itself to
794 KDE's list of screensavers (via xscreensaver.kss.)
795 * Improved detection of GL libraries.
796 * Made the password dialog include the date and time.
797 Changes since 3.16: * New version of `webcollage' -- deals better with
798 corrupted images, and can use an http proxy.
799 * New hack, `xsublim' (run it in the background,
800 rather than adding it to the programs list.)
801 * The xscreensaver daemon was leaking a file descriptor
802 each time you edited your .xscreensaver file. Fixed.
803 Changes since 3.15: * New version of `shadebobs'.
804 * Improved image selection in `webcollage', and sped it
806 * Made configure find the right version of perl.
807 * Rewrote the CGI part of `webcollage'.
808 * `make clean' was deleting some things it shouldn't.
809 * Fixed a typo in the default programs list.
810 Changes since 3.14: * Added `webcollage' and `shadebobs' hacks.
811 * Added a `-stdout' arg to `vidwhacker' so that it can
812 be used in a pipeline.
813 * Made `petri' use less memory.
814 Changes since 3.13: * Various improvements to the Gtk port.
815 * Turned off PAM by default on Solaris, since PAM seems
816 generally to be misconfigured out-of-the-box.
817 * Made the `--without-gtk' configure option work.
818 * Made configure check the Gtk version number, since it
820 * Fixed a bug in the code that attempted to prevent
821 changes of screen resolution while the screen is
823 * Fixed a race condition in `xscreensaver-demo' that
824 could cause an X error at startup.
825 * Added `-transparent' option to `deluxe'.
826 * Added `petri' hack.
827 Changes since 3.12: * Ported `xscreensaver-demo' to Gtk.
828 * Made it possible to build Motif, Gtk, and Athena
829 versions of `xscreensaver-demo' in the same directory
830 without reconfiguring.
831 * Made `xscreensaver-demo' chase symlinks before writing
832 the .xscreensaver file, so that if .xscreensaver is
833 itself a symlink, the underlying file will be replaced
835 * Some Makefile and configure tweaks for Solaris and
837 * Made it possible to set the fire color in `xflame'.
838 * Made transparency work in TrueColor (for `goop' and
840 * Fixed a multi-head bug introduced by the virtual
842 Changes since 3.11: * Made it so that you can't scroll the screen while the
843 lock dialog is up (with XFree86 virtual viewports.)
844 * Fixed a bug in `flag' that caused bob's chin to get cut
845 off after a few iterations.
846 Changes since 3.10: * Made `xjack' be black-on-white-ish, so that it looks
847 less like a computer screen and more like the
848 typewritten paper it's supposed to be.
849 * New version of `pulsar'.
850 * Fixed Solaris compilation problem in `phosphor'.
851 * Made xscreensaver notice XFree86's virtual root window
852 hack, so that if the X server's root window is larger
853 than the monitor's displayable resolution, the screen
854 saver will limit itself to the area that actually
855 appears on the screen.
856 * Made the xscreensaver daemon do a better job of
857 picking the visual class that should be used for GL
858 programs. Less user intervention should be needed
859 now: you can use the logical visual name `GL' instead
860 of having to figure out by hand which one to use.
861 * Oops, the visual was defaulting to "best" instead of
862 "default", because the .xscreensaver file was not being
863 loaded quite early enough.
864 * Made configure figure out how to build icmp ping
865 support into the `sonar' hack automatically.
866 * Made warnings about not being able to read shadow
867 passwords not be printed if compiled with PAM support.
868 * Improved PAM startup diagnostics.
869 * Worked around the Solaris PAM bug that was causing
870 crashes there, so now PAM is turned on by default.
871 * Made configure detect the number of arguments that
872 pam_strerror() takes, since on Linux, this apparently
873 changed between 2.0 and 2.2, sigh.
874 * Made the /proc/interrupts kludge look for "PS/2 Mouse"
875 as well as "keyboard".
876 * Made xscreensaver notice when there has been a sudden
877 large jump in wall-clock time, and if so, lock right
878 away, instead of waiting for "lockTimeout" to expire
879 first. (Laptops need this for safer recovery from
881 * Added `-throttle' option to `xscreensaver-command'.
882 Changes since 3.09: * Added `phosphor', `xmatrix', and `pulsar' hacks.
883 * Fixed a bug in the color allocator that sometimes
884 caused `starfish' to fall back to monochrome.
885 * Reduced the amount of code that runs before root
886 privileges are disavowed: "normal" and "shadow"
887 passwords now do some initialization as root, but the
888 PAM and Kerberos authorization schemes will be
889 initialized while running as "nobody". Supposedly
890 this closes a potential security hole when using
892 * Added some more sanity checking to configure.
893 Changes since 3.08: * Added `compass', `squiral', `xflame', `wander',
894 `spotlight', and `critical' hacks.
895 * Added some new modes to `decayscreen'.
896 * Made `deluxe' work in monochrome.
897 * Generalized usage of the Double-Buffer server extension
898 in several hacks (`compass', `deluxe', `interference',
899 `kumppa', and `moire2'.)
900 * Fixed another visual-depth problem in `rd-bomb'.
901 * The screen saver will now defer blanking if neither
902 the keyboard nor the mouse could be grabbed. Instead,
903 it will just try again in a few minutes. This fixes
904 a bad interaction between xscreensaver and programs
905 like VMware that hold the mouse and keyboard grabbed
907 * Added a new erase mode (expanding spiral.)
908 Changes since 3.07: * Fixed some bugs in my port of `t3d'.
909 * Added `penetrate' and `deluxe' hacks.
910 * When linking against Motif 2.x, also link against XPM.
911 * Added support for using /proc/interrupts for idle
912 detection on Linux. Now xscreensaver shouldn't kick
913 in when the user is active on a non-X virtual console.
914 * Upgraded to autoconf 2.13.
915 Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
916 in properly; check for _Xsetlocale in -lXintl.)
917 * Portability fixes for sonar.c.
918 * Fixed a compilation problem when you have GL but don't
920 * Made configure notice when MesaGL requires -lpthread.
921 * Made `flame' ignore SIGFPE (not sure if this is the
922 right fix; it seems only to be needed on FreeBSD.)
923 * Kludged `rd-bomb' work on visuals that are of depth 24
924 but that *do not* support pixmaps of depth 32.
925 * Fixed `halo' to work properly in TrueColor.
926 * Changed `xscreensaver.spec' to install the hacks in
927 /usr/X11R6/lib/xscreensaver/ by default, since that's
928 where recent Red Hat distributions put them.
930 * Updated versions of `crystal', `hopalong', and `flow'
932 * Imported `demon' and `loop' modes from xlockmore.
933 Changes since 3.05: * Oops, the "default-n" visual descriptor was broken;
934 it was always installing a colormap if the
935 `installColormap' preference was set, meaning that
936 `xearth', `xv' and friends were using the wrong
937 colors on 8-bit systems.
938 * Turned off HAVE_PING in `sonar', since it compiles
939 on some Linux systems, but not others of similar
941 Changes since 3.04: * Fixed an off-by-1 in `distort'.
942 * Added `sonar' hack.
943 * New version of `glplanet' (with stars.)
944 * Made all hacks exit when you type `q' or `ESC' at them,
945 and made them obey the WM_DELETE_WINDOW ClientMessage.
946 * Fixed a nonfatal buffer overrun in lament (note:
947 lament still doesn't work with MesaGL 3.0: it dies in
948 lambda_textured_triangle1(), which is Mesa's bug, not
950 Changes since 3.03: * Added an `xscreensaver.spec' file, to make it easier
951 for other folks to generate RPMs.
952 * Made the password code work on HPUX in the situation
953 where: ``enhanced security'' is available; but not
954 used; but the user typed a password more than 8
955 characters long anyway. FTSOHPUX.
956 Changes since 3.02: * Made locking work when passwd aging is enabled.
957 * Added support for PAM (Pluggable Authentication
958 Modules.) It is still turned off by default, though,
959 since it doesn't seem to work on Solaris 2.6, and has
960 been behaving erratically on Red Hat 5.1.
961 * Made each possible authentication method be tried in
962 turn until one succeeds; this means that Kerberos is
963 being used, we will first check Kerberos, and if that
964 fails, will then consult the local password file.
966 * Save and restore the bits under the passwd dialog,
967 to avoid leaving a black rectangle behind when
968 unlocking is cancelled.
969 Changes since 3.01: * Not everyone has sys/select.h, sigh...
970 Changes since 3.00: * Some fixes to `reflect'.
972 * Made it log unsuccessful attempts to unlock the screen
974 * Fixed a bug where `xscreensaver-demo' could be seeing
975 a different programs list than `xscreensaver' did.
976 Changes since 2.34: * The xscreensaver daemon no longer links against Motif
977 or Athena: demo-mode and the preferences panel are no
978 longer built in to the daemon, but are now handled by
979 an external program, `xscreensaver-demo'.
980 (I decided that this, along with the recent addition
981 of the `.xscreensaver' config file, justified bumping
982 the version number to 3.00, since this is a fairly
983 major architectural change.)
984 * Lines in the `*programs' resource may now begin with
985 the character "-", meaning "don't run this hack."
986 In this way, it's possible to disable a hack without
987 throwing away the information about it (making it
988 easier to change your mind later.) Eventually the
989 preferences/demo mode GUI should represent this as a
990 checkbox or something.
991 * Fixed a short race condition where it was possible for
992 xscreensaver to die with a BadWindow error if it was
993 blanking the screen just as another window was being
995 * Made it possible to disable specific modes in `bsod'.
996 Changes since 2.33: * Fixed a bug that was making `pipes' generate way too
997 many valves. Made the viewpoint in `pipes' be selected
998 randomly instead of always being -10 degrees.
999 * Fixed a bug in the XSHM code, in the case where the
1000 server supports the XSHM extension but is not the same
1001 machine as the client.
1002 * Made `rd-bomb' default to taking up the whole screen.
1003 * Made it not try to do fading/unfading if no PseudoColor
1005 * Initial attempt at supporting VT-locking (doesn't work
1007 * Eliminated the `captureStdout' resource; now
1008 `captureStderr' controls both streams.
1009 * Added `-capture-stderr' and `-no-capture-stderr'
1010 command-line arguments.
1011 * Added `glplanet' hack.
1012 * When a hack is selected with `xscreensaver-command
1013 -select', that hack will be used until further notice
1014 (until the saver turns off, or another activation
1016 Changes since 2.32: * Made `xscreensaver-command' print error messages:
1017 the xscreensaver daemon now responds to ClientMessage
1018 events by writing a response message on a window
1019 property, instead of just writing to its stderr.
1020 * Made the ~/.xscreensaver file be automatically reloaded
1021 when the file date changes.
1022 * The password dialog and splash screen no longer depend
1023 on Motif or Athena. This should clear up a number of
1024 focus problems, and is the first step on the path
1025 toward moving all of the Motif/Athena/whatever code
1026 out of the xscreensaver daemon, and into external
1028 * Don't complain about LessTif 0.86 any more, since the
1029 new password dialog makes that problem go away.
1030 * Configure tweaks for Irix 6.5, SunOS 5.something.
1031 * New `-reflect' option to `distort'.
1032 Changes since 2.31: * Added reading and writing of a ~/.xscreensaver file,
1033 so that the Preferences panel can save its settings.
1034 * New version of `rubik'.
1035 * Added `-select N' argument to `xscreensaver-command'.
1036 * Oops, left out some of the `bubbles3d' files...
1037 Changes since 2.30: * The cursor was invisible in the password dialog. Fixed.
1038 * Made configure warn against MesaGL 2.6.
1039 * Fixed X error at startup when using non-default visual.
1040 * New version of `crystal', `ant', and `atlantis' from
1042 * New hack, `bubble3d'.
1043 * Added some new modes to `bsod'.
1044 Changes since 2.29: * Changed the order in which -lSM and -lICE are linked
1045 to be after Motif instead of before (Lesstif on Irix
1047 Changes since 2.28: * Work around a bash bug in configure.
1048 * Tweaked HPUX paths again. FTSOHPUX.
1049 * Made configure recommend against LessTif 0.86, due
1050 to a bug in that version that causes a security hole
1051 in the screen locking code. LessTif 0.87 will fix it.
1052 * Made all of the `--with' options to `configure' accept
1053 a directory option as well (so that --with-motif=/FOO
1054 will add -I/FOO/include -L/FOO/lib). I believe this is
1055 the Configure Party Line of how do to such things.
1056 * Fixed a bug where the mouse was left un-grabbed
1057 after the first time the graphics hack was changed
1058 (simplified all of the mouse-grabbing logic.)
1059 * Maybe possibly perhaps made `vidwhacker' really not
1060 leave stray xv windows around. This time for sure.
1061 * Added a new erase mode (random dots fizzling out.)
1062 * Added `-prefs' argument to `xscreensaver-command',
1063 that brings up the Preferences dialog directly (it
1064 seems that nobody ever noticed the `Preferences' button
1065 on the Demo Mode dialog, maybe this will help.)
1066 * Added a splash screen. Turn it off with *splash:false.
1067 Changes since 2.27: * Better macsbug text in `bsod'.
1068 * New version of `distort' with many new modes.
1069 * Plugged a leak in `coral'.
1070 * Tweaked configure for HPUX.
1071 * Removed some compiler warnings.
1072 * More consistent usage of stderr versus stdout.
1073 * More diagnostics should an X error occur.
1074 * Fixed a possible crash in SGI-specific unfading code.
1075 Changes since 2.26: * Improved version of `distort'.
1076 * Made `lament' compile against OpenGL 1.0 (though it
1077 still requires 1.1 to work properly.)
1078 * Updated my email address and home page.
1079 Changes since 2.24: * Improved motion in `rd-bomb'.
1080 * Added XSHM (shared memory extension) support to the
1081 `distort', `interference', `moire', `rd-bomb', and
1082 `swirl' hacks, which speeds them up a bit.
1083 * Added `lament' hack.
1084 Changes since 2.23: * Tweaked the order of the -L options again.
1085 * Cleaned up configure's `--help' message.
1086 * Added `kumppa' hack.
1087 * Smarter maze-solving algorithm in `maze'.
1088 * Took `xlyap' out of the default list of hacks, since
1089 it's just incredibly buggy (and slow.) Maybe someday
1090 someone will fix it...
1091 * Added `distort' hack, but didn't add it to the default
1092 list (yet) because it's still too slow.
1093 * Made the Athena demo dialog look more like the Motif
1094 version; it has a text-entry field now, too.
1095 * Made the Athena password dialog echo asterisks, like
1096 Motif does, instead of using a flyspeck font.
1097 * Some random configure tweaks.
1098 * Added a `timestamp' resource that makes the `-verbose'
1099 messages include the time at which they were printed.
1100 Changes since 2.22: * The fix for SGI's ``scheme'' nonsense broke things, and
1101 let the user's "*background" resource show through.
1102 Fixed it in a different way.
1103 Changes since 2.21: * Added support for the DPMS server extension (Display
1104 Power Management System.)
1105 * Made configure advertize the `--enable-subdir' option a
1106 little more, since that seemed to cause some people
1107 stress. Also, made that directory be built into the
1108 xscreensaver executable, as a hardcoded prefix to
1109 $PATH. (Might help, shouldn't hurt.)
1110 * Made configure prefer the two-arg gettimeofday to the
1111 one-arg version, since AIX doesn't have any prototypes.
1112 * Made it work with Xaw3d (the 3D Athena library.)
1113 * Made `make install' create directories as necessary.
1114 * New version of lmorph from Sverre.
1115 * Added `crystal' and `discreet' hacks from xlockmore.
1116 * Added a new mode to `bsod'.
1117 Changes since 2.20: * Made `xscreensaver-command -time' use different words.
1118 (It now describes the two states as "screen blanked
1119 since..." and "screen non-blanked since..." instead of
1120 "active since..." and "inactive since..." which a lot
1121 of people interpreted as meaning the opposite of what
1123 * Improved some error messages, in the hopes of making
1124 the distinction between the xscreensaver and
1125 xscreensaver-command programs more obvious.
1126 * Rewrote (and reorganized) parts of the xscreensaver and
1127 xscreensaver-command manual pages.
1128 * Renamed xscreensaver's `-lock' command-line option to
1129 be `-lock-mode', to avoid confusion with the `-lock'
1130 option to xscreensaver-command, which does a totally
1132 * Removed xscreensaver's `-demo' command-line option for
1133 a similar reason; use `xscreensaver-command -demo'
1135 * Disabled SGI's ``scheme'' nonsense in a better way than
1136 fully-qualifying the background colors in every single
1138 * Fixed some other minor cosmetic problems when *sgiMode
1140 * Fixed an X error in `bsod -root' (how ironic...)
1141 Changes since 2.19: * Fixed a bug that caused the mouse to sometimes not be
1142 grabbed properly (meaning the window manager menu could
1143 pop up over the demo-mode display.)
1144 * Fixed a bug that made the stderr output sometimes get
1146 * Fixed a bug that made the demo-mode scrollbar move too
1148 * Protected against a possible buffer overflow.
1149 * Made `vidwhacker' not leave stray xv windows around.
1150 * New version of `ant' so that Bagley doesn't calve.
1151 * Make configure on AIX get XShm from the right library.
1152 Changes since 2.18: * One file was missing from the tar file. Fixed.
1153 Changes since 2.17: * Oops, atlantis wasn't being built by default. Fixed.
1154 * Added `epicycle' hack.
1155 * Added `interference' hack.
1156 * Added `truchet' hack.
1157 * Added `bsod' hack.
1158 * Added some new modes to `vidwhacker'.
1159 Changes since 2.16: * Added a -window-id argument to most hacks, so that they
1160 can draw on arbitrary externally-provided windows.
1161 * Synched with xlockmore 4.11a01.
1162 * Added `flow' hack.
1163 * Added `atlantis' GL hack.
1164 * Renamed `puzzle' hack to `jigsaw', since xlock already
1165 had a different mode called `puzzle'.
1166 * Made it self-configure properly when Motif 2.1.0 is
1167 being used (requires -lXp now, sigh...)
1168 Changes since 2.15: * Made `flag' able to do XPM images.
1169 * New look for the xscreensaver logo (`xroger').
1170 * Fixed compilation error on Suns with adjunct passwords.
1171 * Got multi-architecture builds working again.
1172 * Some configure tweaks for building on HPUX and Solaris.
1173 * Fixed bug in decayscreen.

1181 * Added `stairs' hack.
1182 * Split `escher' into `cage' and `moebius', as per
1184 * Changed subprocess handling to use sigaction() instead
1185 of signal() if it's available (this is necessary for
1186 SCO but should work fine on other systems too.)
1187 * Various other tweaks.
1188 Changes since 2.13: * Better fix for the Motif drag-and-die lossage.
1189 * Put in some kludges to work around a LessTif bug.
1190 * XScreenSaver is known to work with LessTif 0.82 now.
1191 * Made fading work on high-end SGI video hardware.
1192 * Fixed another SGI-specific bug in screen grabbing;
1193 will the madness never cease?
1194 * Fixed another crash in `xlyap'.
1195 Changes since 2.12: * Made `decayscreen' do directions other than down.
1196 * Improved `puzzle'.
1197 * Fixed a crash in `xlyap'.
1198 * Added CDE info to the man page, removed `cde.txt'.
1199 * Configure tweaks for Zippy.
1200 * Turned off the signal handling in `bubbles' because
1201 it was sometimes failing to die.
1202 * Added `hacks/xscreensaver-sgigl.c' to make it possible
1203 to run SGI's ElectroPaint hack (/usr/demos/bin/ep)
1204 with xscreensaver. Finally!
1205 * Fixed a buffer overrun in the locking code that some
1206 wily, malicious cracker must have slipped in.
1207 * Disabled Motif drag-and-drool in the dialog box
1208 buttons, since it's broken in some old versions of
1210 Changes since 2.11: * Added `README.debugging'.
1211 * Added `puzzle' hack.
1212 * Added `xlyap' hack.
1213 * Added `default-n' as a visual name, so that one can
1214 have -install on by default, but turn it off for
1215 certain poorly-behaved hacks (like xv.)
1216 * Added support for grabbing frames of external video
1217 (on SGI) to the screen-grabbing hacks (decayscreen,
1218 slidescreen, slip, blitspin, and puzzle.)
1219 * Improved look of tiles in `slidescreen'; fixed its
1220 color allocation problem.
1221 Changes since 2.10: * Tweaked `blitspin', added it to the default list.
1222 * Added `lissie', `mountain', `triangle', `worm',
1223 `rotor', and `ant' from xlockmore.

1231 * Fixed compilation problem with Sun's version of OpenGL.
1232 * Added ability to use sigaction() instead of signal()
1233 to work around a SCO kernel bug.

1235 * Configure tweaks for *BSD.
1236 Changes since 2.07: * New hacks `rd-bomb' and `coral'.

1251 * Fixed low-color behavior of `goop', `pyro', `starfish',
1252 `greynetic', `flame', `halo', and `moire'.
1253 Changes since 2.02: * Fixed flicker in `pipes'. Fixed 3d in `bouboule'.

1255 * Added basic dependencies to the Makefile.in files.
1256 Changes since 2.01: * Fixes for compiling with the MIT saver extension.

1258 * Various configure tweaks.
1259 Changes since 2.00: * Added `goop' and `starfish' hacks.

1261 * Made `attraction' use the new colormap allocator.
1262 * Added better $PATH diagnostics.
1263 * There was a bug in frand! Color selection should be
1265 Changes since 1.34: * Converted to use `configure' instead of `imake'.

1274 * Generalized sub-process management (Unix sucks!)
1275 * Added interactive mouse frobbing to Julia.
1276 * Added (untested) support for HPUX shadow passwords.
1277 * Made normal non-shadow passwords be checked if the
1278 shadow passwords aren't accessible for some reason.
1279 Changes since 1.31: * Removed *colorPrograms and *monoPrograms resources:
1280 made it possible to specify the desired visual on a
1282 * Cleaned up / restructured the driver: no more globals.
1283 * Made the Motif and Athena dialogs share more code.
1284 * Probably fixed some Athena colormap-installation bugs.
1285 * Fixed screen grabbing (cmap) on SGI 12-bit PseudoColor.
1286 * Fixed divide-by-zero in bright random colormaps.
1287 * Added an improved version of xlock's `flag' hack.
1288 * Made unfading work better, and not flicker on SGIs.

1295 * Made the driver more careful about not leaving bits on
1296 the screen, or allowing other windows to raise
1297 themselves: it now re-blanks the screen every so often.
1298 * Added `-time' option to `xscreensaver-command'.
1299 * Improved SGI screen-grabbing some more: now it can grab
1300 TrueColor screens into PseudoColor windows and have the
1301 colors still come out semi-reasonably.
1302 Changes since 1.29: * Made `slidescreen' and `decayscreen' work better on
1303 SGIs when windows of different visuals are present, by
1304 using the XReadDisplay() extension to get a true 24-bit
1305 image out of the frame buffer.
1306 * Made `noseguy' be in color, if compiled with XPM.
1307 * Ported `braid', `drift', `fract', `galaxy', `grav',
1308 `ifs', `julia', `laser', `lightning', `penrose',
1309 `sierpinski', `slip', `spiral', and `strange' hacks
1311 * Merged `hopalong' hack with a more recent version.
1313 Changes since 1.27: * Added `deco', `moire', and `kaleidescope' hacks.
1314 * Merged in support for non-Motif locking and demo mode.
1315 * Made `blitspin' and `bubbles' work in TrueColor.

1324 * Fixed possible bad color choices in qix and attraction.
1325 * Added ramp-mode to halo.

1327 than using the RNG in libc.
1328 * Made locking work on SCO.
1329 * Various other minor tweaks that I don't remember.
1330 Changes since 1.24: * Made it capture the stdout/stderr of its subprocesses
1331 and present them on the screensaver window itself.
1332 * Made demo mode work correctly with non-default visuals
1333 and color maps, instead of always using the defaults.
1334 * Added -visual argument to all included screenhacks.
1335 * Support for the R6 MIT-SCREEN-SAVER server extension.
1336 * Made the demo mode list scroll properly.
1337 * Added `pedal' hack.
1338 Changes since 1.23: * Fixed some private-colormap oddities in slidescreen,
1339 decayscreen, and xroger. Fixed apparent conservation-
1340 of-mass problem in pyro; made the shrapnel round.
1341 Changes since 1.22: * Minor tweaks for IRIX5; fixed locking race condition.
1342 Changes since 1.21: * Minor tweaks for X11R6.
1343 * Fixes for non-default visuals.
1344 Changes since 1.20: * Fixed bug in color blitspin; added default image.
1345 * Added diagnostics to noseguy. Fixed off-by-one

1358 * Moved the hacks into their own directory.
1359 * Made all `time' parameters accept the 00:00:00 syntax,
1360 so that even the parameters which are normally read as
1361 minutes can be specified in seconds.
1362 * Added colormap cycling to `imsmap'.
1363 * Made hyper work with K&R compilers.
1364 Changes since 1.13: * Added `orbit' option to `attraction' hack.

1372 * Can use `xv' as a slideshow without using up colormap
1373 entries while the screen is not blanked.
1374 * Fixed a BadDrawable error in non-XIdle mode.
1375 * Added `blitspin' and `imsmap'.
1376 Changes since 1.0: * Current list of included hacks is now: qix, helix,
