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

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

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

115 entering numbers that are out of range.
116 * Added "Reset to Defaults" button on X11.
117 * Added relevant Wikipedia links to many of the screen

120 * The `-fps' option now shows CPU load.
121 Changes since 5.05: * Xinerama/RANDR fixes: this time for sure. It should
122 now work to add/remove monitors or resize screens at
124 * New hack, `skytentacles'.
125 * New version of `gleidescope'.
126 * Added the `-log' option to the xscreensaver daemon,
127 since a truly shocking number of Linux users seem to
128 have no idea how to redirect output to a file.
129 * Added `-duration' arg to most image-loading hacks,
130 so that they pick a new image every few minutes.
131 * Added an ATM crash to BSOD.
132 Changes since 5.04: * New hacks, `cubicgrid', `hypnowheel', and
133 `lcdscrub' (which isn't really a screen saver).
134 * Updates to `m6502' and `gears'.
135 * Fixed double-buffering problems in `cubestorm' and
137 * Better handling of horizontal scroll wheels.
138 * Attempt to work around latest Xinerama braindamage:
139 if the server reports overlapping screens, use the
140 largest non-overlapping rectangles available.
141 * Don't warning about receipt of bogus ClientMessages,
142 since Gnome's just never going to stop sending those.
143 * Worked around MacOS 10.5 perl bug that caused the
144 text-displaying hacks to fail on some systems.
145 * Hopefully fixed font-related System Preferences crashes
147 * The recent PAM changes broke the "Caps Lock" warning
148 in the password dialog, the failed login warnings, and
149 syslogging. Fixed all that.
150 Changes since 5.03: * Fixed a possible crash in the unlock dialog (more
151 fallout from the recent PAM changes...)
152 * New hacks, `moebiusgears', `abstractile', and
154 * Rewrote `gears' to use better (involute) gear models,
155 and to be more random.
156 * Minor updates to `cwaves', `voronoi', `deco',
157 `glcells', `rd-bomb', `fireworkx' and `webcollage'.
158 * `pong' can now display the current time as the score.
159 * `xmatrix -mode pipe' works better.

169 * Fixed a Xinerama crash when changing the screen count.
170 * New blobbier `mirrorblob'.
171 * Minor updates to `lisa', `bsod', `ifs', `hypertorus',
172 `polytopes', `circuit', `endgame', `crackberg',
173 `flipflop', `flipscreen3d', `fliptext', and `carousel'.
174 * Enabled multi-threaded OpenGL on MacOS.
175 Changes since 5.00: * Backed out recent locale-related changes, since they
176 broke far more things than they fixed.
177 * Fail gracefully with ridiculously small window sizes.
178 * `xflame' and `flag' ignore bitmap option on MacOS.
179 * `speedmine' prefs work on MacOS.
180 * Better explosions in `boxed'.
181 * More dynamic motion in `sproingies'.
182 * More options in `flipflop'.
183 * Minor updates to `topblock'.
184 * Various other minor fixes.
185 Changes since 4.24: * Ported to MacOS X! (10.4.0 or newer)
186 * API change: instead of providing a single screenhack()
187 function that does not return, screen savers using the
188 screenhack.h framework must now provide "init" and
189 "draw one frame" functions instead. All bundled savers
190 have been updated; third-party patches will need work.
191 * All image-loading happens asynchronously.
192 * xscreensaver-getimage-file caches the contents of the
193 image directory for a few hours, so consecutive runs
194 won't have to re-list the whole directory tree.
195 * New hacks, `topblock' and `glschool'.
196 * Removed `xteevee' (superceded by `xanalogtv').
197 * Added variable-sized puzzle pieces to `jigsaw'.
198 * Changes to the defaults and command-line options of
199 many hacks to make the .xml files more consistent.
200 * Reap zombies in `glslideshow' and `carousel'.
201 * `sonar' works without setuid on MacOS (dgram icmp).
202 * `xmatrix -mode pipe' displays the text of a subprocess.
203 * `endgame' has higher resolution chess-piece models.
204 * `webcollage' takes a -directory option to get images
205 from a local directory.
206 * The RPM spec file no longer auto-restarts xscreensaver
207 when a new version is installed. Restart it manually.
208 Changes since 4.23: * New versions of `cube21', `glsnake', `celtic'.
209 * Backed out a DPMS-related patch that cause desktop
210 flickering with some X servers.
211 * Fixed startup crash in getgroups() when running setuid.
212 * Default to not displaying stderr on the saver window.
213 * Fixed bad free() in "Documentation" button.
214 * Don't try to run hacks that aren't installed.
215 * Minor fixes to various XML config files and man pages.
216 Changes since 4.22: * New hacks, `glhanoi', `cube21', `timetunnel',
217 `juggler3d', and `celtic'.
218 * New versions of `tangram', `webcollage', `hypertorus',
219 `polytopes', and `ripples'.
220 * `sonar' is now quiet about unresolvable hosts.
221 * Minor corrections to BASIC code in `apple2'.
222 * xscreensaver-demo now provides an RPM clue when none
223 of the hacks seem to be installed.
224 * Don't install `ant' by default, since there is some
225 Java tool of that name, which was causing confusion.
226 And also it's boring.
227 * Made screen grabbing work again on MacOS 10.4.2.
228 * No longer prints bogus warnings about ClientMessages
229 intended for the window manager.
230 * Ignore unprintable characters in passwd entry field.
231 * Fixed yet another cross-host-display image-loading
233 * `xscreensaver-command -watch' and `-time' now work
235 Changes since 4.21: * Fixed a bug in the new mouse-motion code that caused
236 the screen to never blank on multi-head non-Xinerama
238 * New hacks, `interaggregate', `antmaze', `tangram',
240 * Minor tweaks to `fiberlamp', `ifs', `slidescreen',
241 `zoom', `sonar', `fireworkx', `whirlwindwarp',
242 `bubble3d', and `rd-bomb'.
243 * Added motion blur to `blinkbox'.
244 * `bsod' now includes Longhorn's "RSOD", and OS/2.
245 * Fixed `-wireframe' usage in most hacks and man pages.
246 Changes since 4.20: * New hack: `fliptext'.
247 * Changed default configure installation directories:
248 /usr/bin/ for xscreensaver, etc.;
249 /usr/libexec/xscreensaver/ for hacks;
250 /usr/share/xscreensaver/config/ for xml files.
251 * All the text-manipulating screen savers can have their
252 text source configured via `xscreensaver-demo' now.
253 * xscreensaver.spec now builds three RPMs:
254 base (no hacks); extras (2d hacks); and gl-extras.
255 * Added `-program' and `-front' option to `gltext'.
256 * Added `-shells' to `molecule'.
257 * Fixed text-alpha glitch in `carousel'.
258 * New `pacman': the ghosts can be killed now.
259 * Fixed a bug in screen-grabbing GL hacks where images
260 would be tiled instead of scaled on machines that
261 can't do large textures.
262 * `webcollage' can hit Flickr now.
263 * New (rewritten) implementation of `ifs'.
264 * The unlock dialog can be made to have a "New Login"
265 button that will run `gdmflexiserver'. Experimental!
266 * Fixed non-ASCII display bug in `starwars'.
267 * Configure finds a default for imageDirectory.
268 * "xscreensaver-command -lock" now works even if
269 in "screensaver disabled" mode.
270 * If a bad password is typed while CapsLock is on, the
271 unlock dialog says "CapsLock?" instead of "Sorry".
272 * Mouse motion only counts as activity if the mouse moved
273 more than 10 pixels (so the screen won't unblank every
274 time you bump your desk.)
275 * New mode option "random-same": if you have multiple
276 monitors, this will run the *same* randomly chosen
277 hack on each screen, instead of different ones on each.
278 Changes since 4.19: * New hacks, `fiberlamp', `boing', `boxfit', and
280 * Rewrote `glslideshow' again: should be faster now.
281 * Sped up loading of images in GL programs.
282 * `starwars' uses texture-mapped fonts now.
283 * New `bsod' modes: tru64, hppa, and nvidia.
284 * Updates to `webcollage', `juggle', `pinion',
285 `fireworkx', `sonar', `extrusion', `substrate', and
287 Changes since 4.18: * New hacks, `substrate', `intermomentary', `fireworkx',
289 * New version of `flow'.
290 * Made /proc/interrupts work again on Linux 2.6.
291 * Made `analogtv' not hog the CPU.
292 * Made analogtv-based hacks work properly on PPC/ARM.
293 * Fixed a bad memory leak in `piecewise'.
294 * Minor updates to `sonar', `molecule', `glmatrix',
295 `galaxy', and `webcollage'.
296 * Removed support for GTK 1.x (everyone uses 2.x now.)
297 Changes since 4.17: * Oops, pay no attention to the man behind the curtain.
298 Changes since 4.16: * New hacks, `anemotaxis' and `memscroller'.
299 * Fixed a bad bug that caused `vidwhacker' to never die.
300 * Fixed normals and lighting in `polyhedra'.
301 * Don't reuse the window when changing hacks (to work
302 around bugs in some GL implementations.)
303 * Made `xscreensaver-getimage-file' skip thumbnail-sized
305 * Fixed endian problem in `barcode' on non-x86.
306 * Updates to `webcollage', `apple2', `fuzzyflakes',
307 `atunnel', and `pacman'.
308 * Timing tweaks to `bubble3d', `bouncingcow', `engine',
309 `gltext', `lavalite', `molecule', `spotlight',
310 `sballs', `boxed', `blinkbox', and `circuit'.
311 * Configure updates for Fedora core 2 / xorg 6.7.0.
312 * Compile without warnings under gcc 3.3.3.
313 * I give up: don't blank or lock the screen if we can't
314 get a keyboard grab. In that case, both choices are
316 Changes since 4.15: * New hacks, `polyhedra', `fuzzyflakes', `antinspect',
318 * Minor updates to `webcollage', `bsod', `endgame',
319 `antspotlight', `xmatrix', and `glmatrix'.
320 * Added support for the RANDR (Resize and Rotate)
321 extension to detect when the size of the desktop has
322 been changed while xscreensaver is already running.
323 * Possibly-futile attempt to work around "rdesktop"
325 * Made `xscreensaver-getimage -file' still work even if
326 imageDirectory is unset.
327 * Convert Latin1 to ASCII in `starwars' and `phosphor'
328 (since the GLUT font only has ASCII glyphs.)
329 * Fixed randomization in `noof'.
330 * Added "GetViewPortIsFullOfLies" preference to work
331 around longstanding XFree86 bug #421.
332 * Made `sonar' subnet pinging work properly on bigendian
333 machines (e.g., PPC.)
334 Changes since 4.14: * New hacks, `wormhole', `mismunch', `noof', and
336 * `phosphor' and `apple2' include vt100 emulators now:
337 this means you can do "phosphor -program top", or
338 can use either program as an xterm replacement:
339 "apple2 -text -fast -program 'xemacs -nw'".
340 * `analogtv' (and related) fill the screen better.
341 * The '-gradient' option works in `atlantis' now.
342 * Minor updates to `blinkbox', `queens', `endgame',
343 `glmatrix', `mirrorblob', `blocktube', and `molecule'.
344 * Integrated SuSE's "external passwd helper" support.
345 * Marginally better /tmp handling in various programs.
346 * Updated config defaults for xplanet 1.0.3.
348 Changes since 4.13: * New hacks, `fontglide', `apple2', `xanalogtv', `pong',
349 `gleidescope', `mirrorblob', and `blinkbox'.
350 * New version of `glsnake' (with many more models.)
351 * Another Windows crash in `bsod'; also HVX/GCOS6/TPS6.
352 * New version of `endgame'.
353 * Screen grabbing works on MacOS X.
354 * Various minor fixes.
355 Changes since 4.12: * On Xinerama systems, xscreensaver now runs one hack on
356 each monitor (just like in "real" multi-head mode)
357 instead of running one hack stretching across all the
358 screens. Note that for this to work with any 3rd party
359 screensavers, they must update their "vroot.h" file.
360 * `webcollage' and `vidwhacker' display images using
361 `xscreensaver-getimage' now.
362 * Added `ljlatest' script for use with `starwars' and
364 Changes since 4.11: * New GL hacks, `flipflop', `antspotlight', and
366 * Added VMS to `bsod'.
367 * Compile without warnings in "gcc -pedantic".
368 * Updates to `webcollage' and `queens'.
369 * Fixed a bug that could cause PAM to hang.
370 Changes since 4.10: * New hacks, `hypertorus', `cubestorm', `glknots',
371 `blocktube', and `glmatrix'.
372 * Updates to `cloudlife', `engine', `xmatrix', and
374 * Rewrote `glslideshow': it should work on somewhat
375 wimpier video cards now.
376 * Various portability tweaks.
377 Changes since 4.09: * New hacks, `cloudlife' and `klein'.
378 * Added Apple ][+, HPUX, and OS/390 sessions to BSOD.
379 * Added some Matrix Reloaded text to `xmatrix'.
380 * Updates to `webcollage', `eruption', `jigglypuff',
381 `metaballs', and `endgame'.
382 * Completely ignore the `memoryLimit' setting now,
383 since it was still causing people GL grief.
384 * Various minor fixes.
385 Changes since 4.08: * New hacks, `flyingtoasters', `bouncingcow',
386 `jigglypuff', and `glslideshow'.
387 * More models in `engine'.
388 * Rewrote `xscreensaver-getimage' to remove reliance on
389 external image loaders (xv, chbg, xloadimage, etc.)
390 and to reduce flicker when loading files.
391 * Made `gflux' and `flipscreen3d' be mouse-spinnable.
392 Changes since 4.07: * New hacks, `atunnels' and `piecewise'.
393 * Physics improvement in `fluidballs'.
394 * Various fixes for XDarwin systems (X11 on MacOS X.)
395 * Added -clock option to `barcode'.
396 * Minor fixes to `endgame', `flurry', `flipscreen3d',
398 Changes since 4.06: * New hacks, `flurry', `metaballs', `eruption',
399 `popsquares', and `barcode'.
400 * Minor updates to `maze' for high density mazes.
401 * Added double buffering to `fluidballs' and `whirlygig'.
402 * Bug fixes for running xscreensaver to a remote XFree86
403 display (which nobody would ever do...)
404 * Updated `webcollage' (faster Alta Vista searching.)
405 * Updated `glplanet' so the sun sets in the west.
406 * Updated `sproingies' with smooth, unsegmented surfaces.
407 * Fixed Perl version-sensitivity in
408 `xscreensaver-getimage-file'.
409 * Fixed GTK2 scrolling bug in `xscreensaver-demo'.
410 Changes since 4.05: * New hack, `glblur' (disabled by default, since it
411 requires fast OpenGL texture support.)
412 * New hack, `halftone'.
413 * Updates to `endgame', `queens', `bumps', `glplanet',
414 `engine', and `circuit'.
415 * New version of `menger' that uses far fewer polygons.
416 * Fixed minor bug in `critical' that could cause some
417 bogus X servers to crash.
418 * Better labels in `molecule': the labels now appear to
419 be attached to the atoms, instead of floating in front
421 * Fixed bug that could rarely cause GL hacks to fail to
422 double-buffer (causing intermittent flickering.)
423 * Fixed a relative-URL-parsing bug in `webcollage'.
424 * Fixed a bug that (sometimes) caused the window manager
425 close box to kill `xscreensaver-demo' with a crash
426 instead of a graceful exit.
427 * Updated xscreensaver.pam to the Red Hat 7.3 way.
428 * More Gnome2-related configure crap.
429 * Updated to latest `config.guess' and `config.sub'.
430 * Fixed occasional core dump in `distort'.
431 * Added a Linux fsck failure and kernel panic to `bsod'.
432 * Added MacOS X kernel panic to `bsod'.
433 * Fixed a bug in `bsod' (all bsod bugs are ironic.)
434 * Fixed a bug that caused `xscreensaver-gl-helper' to
435 print a nonsense visual ID with some versions of
436 `printf': this could cause GL programs to display
437 incorrectly (e.g., flickery.)
438 Changes since 4.04: * More `configure' tweaks to try and get things working
439 on systems that both Gtk 1.x and 2.x installed.
440 * New hack, `endgame'.
441 * Minor updates to `gltext'.
442 Changes since 4.03: * Support for GTK 2.x / GNOME 2.x.
443 * The `configure' script will now use `pkg-config' if
444 you have it, in preference to `gtk-config', etc.
445 * New hacks, `lavalite', `queens', and `anemone'.
446 * Minor updates to `spheremonics', `gltext', `xmatrix'.
447 * You can use the mouse to manually spin most of the GL
448 hacks now (when they are displaying in a window.)
449 * Fixed a bug in `webcollage' (due to recent Alta Vista
450 url changes) that was causing it to try and load
451 incorrect image URLs.
452 * Made `xscreensaver-getimage' use gdk_pixbuf if it is
453 available: this means that those hacks that load images
454 will no longer rely on "xv", "xloadimage", etc. This
455 will close a race condition that could sometimes cause
456 your desktop background to be changed; and also makes
457 it possible for those programs to operate on image
458 files when running in windowed mode.
459 * `webcollage' can now be used in conjunction with
460 `driftnet' to display images snooped from your local
461 ethernet instead of obtained from search engines.
462 * Added man pages for all the hacks that didn't have
464 Changes since 4.02: * New hack, `spheremonics'.
465 * Minor updates to `webcollage', `cage', `moebius',
466 `morph3d', `boxed', `circuit', and `helix'.
467 * `pulsar' and `extrusion' can now load texture JPEGs.
468 * `rubik' now does non-square cubes.
469 * `fluidballs' now does various sizes of balls.
470 * `menger' and `sierpinski3d' now also show polygon
472 * `molecule' displays real subscripts in the formulae.
473 * GTK internationalization/localization support.
474 * Better detection of the various versions of libxml.
475 * Upgraded to autoconf 2.53 (from 2.13.)
476 Changes since 4.01: * Plugged a few minor leaks in `xscreensaver' and
478 * New hacks, `cubenetic' and `fluidballs'.
480 * Fixed sphere projection error in `glplanet'; installed
481 a better image of earth.
482 * Added Win2K and MacOS 1 crashes to `bsod'.
483 * Put back previous (better) version of `forest' that
484 was accidentially downgraded in the last release.
485 * New version of `bumps'.
486 * Made FPS computation in GL hacks more efficient: it
487 will influence the results less, thus resulting in
488 higher (but more accurate) reported frame rates.
489 Changes since 4.00: * New hacks: `twang', `glsnake', `boxed', `sballs',
491 * New hacks `apollonian', `euler2d', `juggle',
492 `polyominoes' and `thornbird', from xlockmore.
493 * Merged recent xlockmore changes into `ant', `braid',
494 `demon', `discrete', `drift', `fadeplot', `forest',
495 `grav', `hopalong', `ifs', `laser', `lightning',
496 `lisa', `lissie', `loop', `mountain', `penrose',
497 `rotor', `sierpinski', `slip', `sphere', `spiral',
498 `strange', and `vines'.
499 * Fixed the `gltext' bug that sometimes caused
500 horizontal lines to vanish again. This time for sure.
501 * Sped up `webcollage' by adding a C helper program to
502 replace the PPM pipeline. It also pastes images
503 semi-transparently now.
504 * Added support for the gdk_pixbuf library: if this lib
505 is available, then `blitspin', `xflame', and `flag'
506 can load GIF, JPEG, and PNG images in addition to XPM
508 * Fixed a rare race condition where the desktop-grabbing
509 hacks could sometimes leave the screen wedged, if the
510 user moved the mouse exactly when they were grabbing
511 the screen image (it would un-wedge the next time the
512 saver timed out or was activated.)
513 * Fixed incorrect colors in the screen-grabbing GL hacks
514 (`gflux' and `flipscreen3d'.)
515 * Made SIGHUP restart the daemon process (though using
516 `xscreensaver-command -restart' is still the preferred
518 * Tweaks to `xspirograph'.
519 * Minor configure and portability tweaks.
520 Changes since 3.34: * Redesigned `xscreensaver-demo' GUI: it now includes
521 small-preview and per-hack configuration dialogs.
522 * Added three new modes of operation: `One Screen Saver',
523 `Blank Screen', and `Don't Blank' (in addition to the
524 historical `Random Screen Saver').
525 * Configure now defaults to installing the hacks in
526 <prefix>/lib/xscreensaver/ instead of <prefix>/bin/.
527 (Most distros already did it this way.)
528 * New GL hacks, `menger', `engine', `flipscreen3d'.
529 * Made `sierpinski3d' be more colorful.
530 * New versions of `xmatrix' and `nerverot'.
531 * Fixed a bug in `starwars' that made the font be drawn
532 with thin lines in -root mode.
533 * Fixed a bad colormap bug in `crystal' that could make
534 *subsequent* hacks malfunction!
535 * Made `gflux' able to grab screen images (`-mode grab').
536 * Updated `webcollage' for recent search engine changes.
537 * Removed most command-line options to `xscreensaver':
538 just edit the ~/.xscreensaver file instead.
539 * Improved behavior on multi-screen and Xinerama systems:
540 the mouse now stays on the screen where the user left
541 it, and the password and splash dialogs always appear
542 on the screen that has the mouse.
543 * Made the splash dialog use more Gtk-like colors;
544 made it have only two buttons, "Settings" and "Help".
545 * Made `sonar' understand `.ssh/known_hosts2' format
546 files, and be better about stripping out illegal
548 Changes since 3.33: * Turned `memoryLimit' off by default, sigh. Apparently
549 some versions of the GL libraries (appear to) allocate
550 hundreds of megs for every GL program, so `memoryLimit'
551 was causing GL programs to malfunction or crash on
553 * Improved fading on TrueColor XFree86 4.1.x systems.
554 * New GL hack, `circuit'.
555 * Added `fuzz' mode to `decayscreen'.
556 * New version of `whirlygig'.
557 * Added links to `xplanet' and `sphereEversion'.
558 * Fixed rare race condition that could make `sonar' hang.
559 * Fixed potential crash in `speedmine'.
560 * Made `xscreensaver-demo' not crash when imageDirectory
561 was set to a non-existent directory.
562 * Made `xscreensaver-getimage-video' invoke XawTV's
563 `streamer' program better.
564 * Made `phosphor' and `starwars' deal with CR, LF,
565 or CRLF line endings.
566 * Changes for Cygwin compilation environments.
567 * Made `sonar' compile on systems that can't ping.
568 * Configure changes for HPUX 10.20.
569 * Made PAM code work on Red Had 4.2 systems.
570 * Made `xscreensaver-command -deactivate' work when the
571 saver is not active: what that does is reset the idle
572 timer, as if keyboard input had been detected. This
573 was added for the benefit of people writing DVD-playing
574 software: they can now prevent the screensaver from
575 kicking in by sending a -deactivate message once a
576 minute while the movie is playing and not paused.
577 * Various minor portability tweaks.
578 Changes since 3.32: * New hacks, `speedmine' and `whirlygig'.
579 * Sped up `pyro', made the explosions look a bit better.
580 * Added better stars to `glplanet' and `starwars'.
581 * Many internal changes to `webcollage'.
582 * Some new options to `attraction'.
583 * Minor fix to `noseguy' to avoid un-erased pixels.
584 * Rewrote the screen-eraser effects so that they complete
585 in the same amount of time regardless of how slow
586 your X server is (some of them were glacial on servers
588 * Fixed a potential free memory reference that could
589 sometimes cause a crash at startup.
590 * Possibly fixed a problem that could cause the daemon
591 to crash with an X error. I was never able to
592 reproduce this problem, but I think I might have
593 figured out what caused it.
594 * Worked around a problem that caused PAM authentication
595 to fail on some Red Hat 7.x systems.
596 * Added a `memoryLimit' parameter that controls the
597 amount of memory a graphics hack may allocate: if they
598 try to allocate more than this, malloc() will fail
599 (and they will exit or (safely) crash, rather than
600 hogging memory.) Default is 50M.
601 * Made `gnome-help-browser' be the default way to display
602 man pages in `xscreensaver-demo', if running on a
604 Changes since 3.31: * The image-manipulating hacks (`slidescreen', etc.) can
605 now operate on randomly chosen image files from disk,
606 or on frames captured from the system's video input,
607 instead of (or in addition to) manipulating images of
609 * Rewrote `vidwhacker' to use the new image-grabbing
611 * Made fading work on TrueColor XFree86 4.x systems.
612 * Fixed a subtle rendering bug in `atlantis' (the fish
614 * Made `atlantis' have a texture simulating light
615 reflections from the surface of the ocean.
616 * Fixed up label placement in `molecule'.
617 * Better color bars in `xteevee'.
618 * Made `install-strip' not try to strip scripts.
619 Changes since 3.30: * Put in more sensible defaults for DPMS, and updated
620 the documentation to reflect the fact that all your
621 DPMS settings are now belong to xscreensaver.
622 * Fixed the `xscreensaver.spec' file so that `--force'
624 * New versions of `rotzoomer' and `nerverot'.
625 * Fixed an OSF/1 compilation problem in `molecule'.
626 Changes since 3.29: * New hacks, `molecule', `dangerball', and `rotzoomer'.
627 * New version of `gflux'.
628 * Made `gltext' able to display the current time.
629 * Fixed a floating-point-precision problem in `gltext'
630 that sometimes caused horizontal lines to vanish.
631 * Removed the `-window-id' option from the hacks:
632 it never worked right, and was unnecessary.
633 * Made the `starwars' hack use thicker lines, antialias
634 the text, and fade out at the far edge instead of just
636 * Fixed an SHM segment leak in `moire'.
637 Changes since 3.28: * Better rendering of the new logo.
638 * New hack, `gltext'.
639 * Added `-planetary' option to `gears', to draw a
640 different kind of gear system.
641 * Made motion and rotation be smoother in `gears',
642 `glplanet', `moebius', `rubik', and `sierpinski3d'.
643 * Improved coloration in `sierpinski3d'.
644 * Made the GL hacks react to window size changes.
645 * Made most of the GL hacks take a -fps option (like
646 `pulsar' did), so you can use them to benchmark your
648 * Fixed the previous fix to `sonar'.
649 * Minor fix to `nerverot'.
650 Made sonar able to ping hosts on DEC OSF1.
651 * Eliminated a bogus "didn't get enough colors" warning
652 in some of the hacks.
653 Changes since 3.27: * New logo for xscreensaver!
654 * New hacks, `starwars' and `stonerview'.
655 * Made the motion of the bouncing ball in `stairs' be a
657 * Made newly-added screenhacks be added to .xscreensaver
658 automatically: if there are hacks in the app-defaults
659 file that are not also in ~/.xscreensaver, they will
660 be added to the end of the list.
661 * Redid the `Screensaver Options' part of the control
662 panel; xscreensaver now lets you configure your DPMS
664 * Fixed some Makefile problems with non-GL builds.
665 * Fixed detection of MesaGL for version 3.3.
666 * Better workaround to Red Hat 7.0's broken gcc.
667 * Added Sparc Solaris kernel panic to `bsod'.
668 Changes since 3.26: * New hacks: `zoom' and `whirlwindwarp'.
669 * Fixed a free-memory-reference bug in `sonar'.
670 * Better error handling when there are no suitable GL
672 * Added diagnostic dialog when xscreensaver-demo is
673 unable to launch xscreensaver (e.g., when running as
675 * Fixed a bug that caused screenhack argument changes
676 to be ignored when xscreensaver-demo was running as
677 root (if "root" and "nobody" have different home
679 * Made the programs default to ":0" if $DISPLAY is unset.
680 * Made the `-verbose' output include information about
681 which server extensions were supported at compile time.
682 * Worked around Red Hat 7.0's broken gcc 2.96.
683 * Updated default delays on the GL hacks to look better
684 on machines with super-fast 3D hardware.
685 * Install `screensaver-properties-capplet' to work around
686 the usual egregious GNOME lossage.
687 Changes since 3.25: * Added "enabled" checkboxes in the list of hacks in
688 xscreensaver-demo (Gtk version only.)
689 * New hacks `hyperball', `xrayswarm', and `gflux'.
690 * New versions of `nerverot', `galaxy', and `hypercube'.
691 * Small fixes to `phosphor', `shadebobs', `xflame',
693 * Added external helper program `xscreensaver-gl-helper'
694 to figure out which X visual to use for OpenGL
696 * Configure updates for XFree86 4.0, and for BSD.
697 * Made it be more tolerant of bogus /etc/group files.
698 * When installing the PAM config file, first try to just
699 copy an existing "xdm" or "login" config file, so that
700 xscreensaver does authentication in the same way as the
702 Changes since 3.24: * New hack, `nerverot'.
703 * Added BSD kernel panic to `bsod'.
704 * New version of `shadebobs'.
705 * New version of `petri'.
706 * Updated `webcollage' to handle recent Altavista URL
707 format changes; made it search the AP photo gallery.
708 * Revamped command-line options of `sonar' and made it
709 properly handle subnets.
710 * The `bubbles' hack can now trickle up or down the
712 * The `xsublim' hack can now read its text from programs.
713 * Support for GLE version 3 in `extrusion'.
714 * Fixed compilation problems in `maze'.
715 * Fixed a rare crash in `flow'.
716 * Fixes for minor installation problems.
717 Changes since 3.23: * Added `-ignorant' option to `maze' hack.
718 * Updates to `critical', `bsod', `xflame', and `flow'.
719 * Added support for Kerberos 5 (via its Kerberos 4
720 compatibility layer.)
721 * Fixed a bad leak in `xteevee'.
722 * Updated `webcollage' to handle recent Altavista URL
724 * Removed xscreensaver-demo's `Ok' and `Cancel' buttons,
725 since they were confusing people: all changes are now
727 * Made xscreensaver-demo install itself into the Gnome
729 Changes since 3.22: * Fixed some misplaced text fields in the Motif version
730 of xscreensaver-demo; fixed a crash in the Gtk version
731 that would happen if the programs list was empty.
732 * Fixed a recently-introduced bug in `pulsar'.
733 * Made `sierpinski3d' use solid tetrahedrons instead of
735 * Added `-trace' option to `xmatrix'.
736 * Added new hacks `xteevee' and `xspirograph'.
737 Changes since 3.21: * Fixed some bugs in xscreensaver-demo.
738 * Rewrote the Motif version of xscreensaver-demo to
739 match the new Gtk version.
740 * The Athena toolkit is no longer supported.
741 Changes since 3.20: * Tweaked the xscreensaver-demo UI (Gtk only.)
742 * Fixed a few visual selection bugs. I think the proper
743 GL visual should be used with nVidia systems now.
744 * Made the Makefiles obey $install_prefix.
745 * Made the `xscreensaver.spec' file able to generate both
746 GL and non-GL packages simultaneously.
747 Changes since 3.19: * Added new hacks `ripples' and `sierpinski3d'.
748 * Made `xscreensaver-command -exit' be silent when no
749 screen saver was running (instead of complaining.)
750 * Made `webcollage' and `vidwhacker' use `xloadimage'
751 when available (in addition to `xli' and `xv'.)
752 * Improved memory usage in `petri' and gave it a hard
753 cap on how much memory it can allocate.
754 * Added `-watch' option to `xscreensaver-command'.
755 * Made `xscreensaver-demo' come up with the
756 most-recently-run hack selected by default.
757 * Rewrote the Gtk version of `xscreensaver-demo'.
758 It's a lot easier to use now.
759 * Extended the format of the programs list in the
760 .xscreensaver file, for the benefit of the new
761 capabilities of `xscreensaver-demo'.
762 NOTE: you might want to delete your ~/.xscreensaver
763 file and allow it to be re-created! The old one
764 should still work, but xscreensaver-demo won't be as
766 Changes since 3.18: * Fixed gcc dependencies in `bumps' and `ccurve'.
767 * New hack, `extrusion'.
768 * Some of the web sites that `webcollage' was using as
769 its sources changed formats; tweaked it to understand
771 * Added typeahead in the password dialog: if the screen
772 is locked, and you unlock it by typing a character,
773 that key will be automatically inserted in the
774 password dialog (unless it is Return, Enter, Space,
775 or a non-printing key like Shift.)
776 * Made `xmatrix' take a `-small' option, since some
777 folks with tiny screens prefer a smaller font.
778 Changes since 3.17: * New versions of `shadebobs', `lmorph', and `distort'.
779 * Added `ccurve', `blaster', and `bumps' hacks.
780 * Replaced `forest' hack with a rewritten version.
781 * Worked around a Xinerama server bug.
782 * Fixed a bug I introduced in 3.10 that caused some
783 hacks to print out superfluous warnings about not
784 having gotten enough colors.
785 * Made `sproingies' obey the `-delay' option.
786 * Fixed a portability bug in `shadebobs'.
787 * Made `webcollage' and `vidwhacker' use `xli' in
788 preference to `xv', if it is available.
789 * Added a new source of images to `webcollage'.
790 * If running under KDE, xscreensaver will add itself to
791 KDE's list of screensavers (via xscreensaver.kss.)
792 * Improved detection of GL libraries.
793 * Made the password dialog include the date and time.
794 Changes since 3.16: * New version of `webcollage' -- deals better with
795 corrupted images, and can use an http proxy.
796 * New hack, `xsublim' (run it in the background,
797 rather than adding it to the programs list.)
798 * The xscreensaver daemon was leaking a file descriptor
799 each time you edited your .xscreensaver file. Fixed.
800 Changes since 3.15: * New version of `shadebobs'.
801 * Improved image selection in `webcollage', and sped it
803 * Made configure find the right version of perl.
804 * Rewrote the CGI part of `webcollage'.
805 * `make clean' was deleting some things it shouldn't.
806 * Fixed a typo in the default programs list.
807 Changes since 3.14: * Added `webcollage' and `shadebobs' hacks.
808 * Added a `-stdout' arg to `vidwhacker' so that it can
809 be used in a pipeline.
810 * Made `petri' use less memory.
811 Changes since 3.13: * Various improvements to the Gtk port.
812 * Turned off PAM by default on Solaris, since PAM seems
813 generally to be misconfigured out-of-the-box.
814 * Made the `--without-gtk' configure option work.
815 * Made configure check the Gtk version number, since it
817 * Fixed a bug in the code that attempted to prevent
818 changes of screen resolution while the screen is
820 * Fixed a race condition in `xscreensaver-demo' that
821 could cause an X error at startup.
822 * Added `-transparent' option to `deluxe'.
823 * Added `petri' hack.
824 Changes since 3.12: * Ported `xscreensaver-demo' to Gtk.
825 * Made it possible to build Motif, Gtk, and Athena
826 versions of `xscreensaver-demo' in the same directory
827 without reconfiguring.
828 * Made `xscreensaver-demo' chase symlinks before writing
829 the .xscreensaver file, so that if .xscreensaver is
830 itself a symlink, the underlying file will be replaced
832 * Some Makefile and configure tweaks for Solaris and
834 * Made it possible to set the fire color in `xflame'.
835 * Made transparency work in TrueColor (for `goop' and
837 * Fixed a multi-head bug introduced by the virtual
839 Changes since 3.11: * Made it so that you can't scroll the screen while the
840 lock dialog is up (with XFree86 virtual viewports.)
841 * Fixed a bug in `flag' that caused bob's chin to get cut
842 off after a few iterations.
843 Changes since 3.10: * Made `xjack' be black-on-white-ish, so that it looks
844 less like a computer screen and more like the
845 typewritten paper it's supposed to be.
846 * New version of `pulsar'.
847 * Fixed Solaris compilation problem in `phosphor'.
848 * Made xscreensaver notice XFree86's virtual root window
849 hack, so that if the X server's root window is larger
850 than the monitor's displayable resolution, the screen
851 saver will limit itself to the area that actually
852 appears on the screen.
853 * Made the xscreensaver daemon do a better job of
854 picking the visual class that should be used for GL
855 programs. Less user intervention should be needed
856 now: you can use the logical visual name `GL' instead
857 of having to figure out by hand which one to use.
858 * Oops, the visual was defaulting to "best" instead of
859 "default", because the .xscreensaver file was not being
860 loaded quite early enough.
861 * Made configure figure out how to build icmp ping
862 support into the `sonar' hack automatically.
863 * Made warnings about not being able to read shadow
864 passwords not be printed if compiled with PAM support.
865 * Improved PAM startup diagnostics.
866 * Worked around the Solaris PAM bug that was causing
867 crashes there, so now PAM is turned on by default.
868 * Made configure detect the number of arguments that
869 pam_strerror() takes, since on Linux, this apparently
870 changed between 2.0 and 2.2, sigh.
871 * Made the /proc/interrupts kludge look for "PS/2 Mouse"
872 as well as "keyboard".
873 * Made xscreensaver notice when there has been a sudden
874 large jump in wall-clock time, and if so, lock right
875 away, instead of waiting for "lockTimeout" to expire
876 first. (Laptops need this for safer recovery from
878 * Added `-throttle' option to `xscreensaver-command'.
879 Changes since 3.09: * Added `phosphor', `xmatrix', and `pulsar' hacks.
880 * Fixed a bug in the color allocator that sometimes
881 caused `starfish' to fall back to monochrome.
882 * Reduced the amount of code that runs before root
883 privileges are disavowed: "normal" and "shadow"
884 passwords now do some initialization as root, but the
885 PAM and Kerberos authorization schemes will be
886 initialized while running as "nobody". Supposedly
887 this closes a potential security hole when using
889 * Added some more sanity checking to configure.
890 Changes since 3.08: * Added `compass', `squiral', `xflame', `wander',
891 `spotlight', and `critical' hacks.
892 * Added some new modes to `decayscreen'.
893 * Made `deluxe' work in monochrome.
894 * Generalized usage of the Double-Buffer server extension
895 in several hacks (`compass', `deluxe', `interference',
896 `kumppa', and `moire2'.)
897 * Fixed another visual-depth problem in `rd-bomb'.
898 * The screen saver will now defer blanking if neither
899 the keyboard nor the mouse could be grabbed. Instead,
900 it will just try again in a few minutes. This fixes
901 a bad interaction between xscreensaver and programs
902 like VMware that hold the mouse and keyboard grabbed
904 * Added a new erase mode (expanding spiral.)
905 Changes since 3.07: * Fixed some bugs in my port of `t3d'.
906 * Added `penetrate' and `deluxe' hacks.
907 * When linking against Motif 2.x, also link against XPM.
908 * Added support for using /proc/interrupts for idle
909 detection on Linux. Now xscreensaver shouldn't kick
910 in when the user is active on a non-X virtual console.
911 * Upgraded to autoconf 2.13.
912 Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
913 in properly; check for _Xsetlocale in -lXintl.)
914 * Portability fixes for sonar.c.
915 * Fixed a compilation problem when you have GL but don't
917 * Made configure notice when MesaGL requires -lpthread.
918 * Made `flame' ignore SIGFPE (not sure if this is the
919 right fix; it seems only to be needed on FreeBSD.)
920 * Kludged `rd-bomb' work on visuals that are of depth 24
921 but that *do not* support pixmaps of depth 32.
922 * Fixed `halo' to work properly in TrueColor.
923 * Changed `xscreensaver.spec' to install the hacks in
924 /usr/X11R6/lib/xscreensaver/ by default, since that's
925 where recent Red Hat distributions put them.
927 * Updated versions of `crystal', `hopalong', and `flow'
929 * Imported `demon' and `loop' modes from xlockmore.
930 Changes since 3.05: * Oops, the "default-n" visual descriptor was broken;
931 it was always installing a colormap if the
932 `installColormap' preference was set, meaning that
933 `xearth', `xv' and friends were using the wrong
934 colors on 8-bit systems.
935 * Turned off HAVE_PING in `sonar', since it compiles
936 on some Linux systems, but not others of similar
938 Changes since 3.04: * Fixed an off-by-1 in `distort'.
939 * Added `sonar' hack.
940 * New version of `glplanet' (with stars.)
941 * Made all hacks exit when you type `q' or `ESC' at them,
942 and made them obey the WM_DELETE_WINDOW ClientMessage.
943 * Fixed a nonfatal buffer overrun in lament (note:
944 lament still doesn't work with MesaGL 3.0: it dies in
945 lambda_textured_triangle1(), which is Mesa's bug, not
947 Changes since 3.03: * Added an `xscreensaver.spec' file, to make it easier
948 for other folks to generate RPMs.
949 * Made the password code work on HPUX in the situation
950 where: ``enhanced security'' is available; but not
951 used; but the user typed a password more than 8
952 characters long anyway. FTSOHPUX.
953 Changes since 3.02: * Made locking work when passwd aging is enabled.
954 * Added support for PAM (Pluggable Authentication
955 Modules.) It is still turned off by default, though,
956 since it doesn't seem to work on Solaris 2.6, and has
957 been behaving erratically on Red Hat 5.1.
958 * Made each possible authentication method be tried in
959 turn until one succeeds; this means that Kerberos is
960 being used, we will first check Kerberos, and if that
961 fails, will then consult the local password file.
963 * Save and restore the bits under the passwd dialog,
964 to avoid leaving a black rectangle behind when
965 unlocking is cancelled.
966 Changes since 3.01: * Not everyone has sys/select.h, sigh...
967 Changes since 3.00: * Some fixes to `reflect'.
969 * Made it log unsuccessful attempts to unlock the screen
971 * Fixed a bug where `xscreensaver-demo' could be seeing
972 a different programs list than `xscreensaver' did.
973 Changes since 2.34: * The xscreensaver daemon no longer links against Motif
974 or Athena: demo-mode and the preferences panel are no
975 longer built in to the daemon, but are now handled by
976 an external program, `xscreensaver-demo'.
977 (I decided that this, along with the recent addition
978 of the `.xscreensaver' config file, justified bumping
979 the version number to 3.00, since this is a fairly
980 major architectural change.)
981 * Lines in the `*programs' resource may now begin with
982 the character "-", meaning "don't run this hack."
983 In this way, it's possible to disable a hack without
984 throwing away the information about it (making it
985 easier to change your mind later.) Eventually the
986 preferences/demo mode GUI should represent this as a
987 checkbox or something.
988 * Fixed a short race condition where it was possible for
989 xscreensaver to die with a BadWindow error if it was
990 blanking the screen just as another window was being
992 * Made it possible to disable specific modes in `bsod'.
993 Changes since 2.33: * Fixed a bug that was making `pipes' generate way too
994 many valves. Made the viewpoint in `pipes' be selected
995 randomly instead of always being -10 degrees.
996 * Fixed a bug in the XSHM code, in the case where the
997 server supports the XSHM extension but is not the same
998 machine as the client.
999 * Made `rd-bomb' default to taking up the whole screen.
1000 * Made it not try to do fading/unfading if no PseudoColor
1002 * Initial attempt at supporting VT-locking (doesn't work
1004 * Eliminated the `captureStdout' resource; now
1005 `captureStderr' controls both streams.
1006 * Added `-capture-stderr' and `-no-capture-stderr'
1007 command-line arguments.
1008 * Added `glplanet' hack.
1009 * When a hack is selected with `xscreensaver-command
1010 -select', that hack will be used until further notice
1011 (until the saver turns off, or another activation
1013 Changes since 2.32: * Made `xscreensaver-command' print error messages:
1014 the xscreensaver daemon now responds to ClientMessage
1015 events by writing a response message on a window
1016 property, instead of just writing to its stderr.
1017 * Made the ~/.xscreensaver file be automatically reloaded
1018 when the file date changes.
1019 * The password dialog and splash screen no longer depend
1020 on Motif or Athena. This should clear up a number of
1021 focus problems, and is the first step on the path
1022 toward moving all of the Motif/Athena/whatever code
1023 out of the xscreensaver daemon, and into external
1025 * Don't complain about LessTif 0.86 any more, since the
1026 new password dialog makes that problem go away.
1027 * Configure tweaks for Irix 6.5, SunOS 5.something.
1028 * New `-reflect' option to `distort'.
1029 Changes since 2.31: * Added reading and writing of a ~/.xscreensaver file,
1030 so that the Preferences panel can save its settings.
1031 * New version of `rubik'.
1032 * Added `-select N' argument to `xscreensaver-command'.
1033 * Oops, left out some of the `bubbles3d' files...
1034 Changes since 2.30: * The cursor was invisible in the password dialog. Fixed.
1035 * Made configure warn against MesaGL 2.6.
1036 * Fixed X error at startup when using non-default visual.
1037 * New version of `crystal', `ant', and `atlantis' from
1039 * New hack, `bubble3d'.
1040 * Added some new modes to `bsod'.
1041 Changes since 2.29: * Changed the order in which -lSM and -lICE are linked
1042 to be after Motif instead of before (Lesstif on Irix
1044 Changes since 2.28: * Work around a bash bug in configure.
1045 * Tweaked HPUX paths again. FTSOHPUX.
1046 * Made configure recommend against LessTif 0.86, due
1047 to a bug in that version that causes a security hole
1048 in the screen locking code. LessTif 0.87 will fix it.
1049 * Made all of the `--with' options to `configure' accept
1050 a directory option as well (so that --with-motif=/FOO
1051 will add -I/FOO/include -L/FOO/lib). I believe this is
1052 the Configure Party Line of how do to such things.
1053 * Fixed a bug where the mouse was left un-grabbed
1054 after the first time the graphics hack was changed
1055 (simplified all of the mouse-grabbing logic.)
1056 * Maybe possibly perhaps made `vidwhacker' really not
1057 leave stray xv windows around. This time for sure.
1058 * Added a new erase mode (random dots fizzling out.)
1059 * Added `-prefs' argument to `xscreensaver-command',
1060 that brings up the Preferences dialog directly (it
1061 seems that nobody ever noticed the `Preferences' button
1062 on the Demo Mode dialog, maybe this will help.)
1063 * Added a splash screen. Turn it off with *splash:false.
1064 Changes since 2.27: * Better macsbug text in `bsod'.
1065 * New version of `distort' with many new modes.
1066 * Plugged a leak in `coral'.
1067 * Tweaked configure for HPUX.
1068 * Removed some compiler warnings.
1069 * More consistent usage of stderr versus stdout.
1070 * More diagnostics should an X error occur.
1071 * Fixed a possible crash in SGI-specific unfading code.
1072 Changes since 2.26: * Improved version of `distort'.
1073 * Made `lament' compile against OpenGL 1.0 (though it
1074 still requires 1.1 to work properly.)
1075 * Updated my email address and home page.
1076 Changes since 2.24: * Improved motion in `rd-bomb'.
1077 * Added XSHM (shared memory extension) support to the
1078 `distort', `interference', `moire', `rd-bomb', and
1079 `swirl' hacks, which speeds them up a bit.
1080 * Added `lament' hack.
1081 Changes since 2.23: * Tweaked the order of the -L options again.
1082 * Cleaned up configure's `--help' message.
1083 * Added `kumppa' hack.
1084 * Smarter maze-solving algorithm in `maze'.
1085 * Took `xlyap' out of the default list of hacks, since
1086 it's just incredibly buggy (and slow.) Maybe someday
1087 someone will fix it...
1088 * Added `distort' hack, but didn't add it to the default
1089 list (yet) because it's still too slow.
1090 * Made the Athena demo dialog look more like the Motif
1091 version; it has a text-entry field now, too.
1092 * Made the Athena password dialog echo asterisks, like
1093 Motif does, instead of using a flyspeck font.
1094 * Some random configure tweaks.
1095 * Added a `timestamp' resource that makes the `-verbose'
1096 messages include the time at which they were printed.
1097 Changes since 2.22: * The fix for SGI's ``scheme'' nonsense broke things, and
1098 let the user's "*background" resource show through.
1099 Fixed it in a different way.
1100 Changes since 2.21: * Added support for the DPMS server extension (Display
1101 Power Management System.)
1102 * Made configure advertize the `--enable-subdir' option a
1103 little more, since that seemed to cause some people
1104 stress. Also, made that directory be built into the
1105 xscreensaver executable, as a hardcoded prefix to
1106 $PATH. (Might help, shouldn't hurt.)
1107 * Made configure prefer the two-arg gettimeofday to the
1108 one-arg version, since AIX doesn't have any prototypes.
1109 * Made it work with Xaw3d (the 3D Athena library.)
1110 * Made `make install' create directories as necessary.
1111 * New version of lmorph from Sverre.
1112 * Added `crystal' and `discreet' hacks from xlockmore.
1113 * Added a new mode to `bsod'.
1114 Changes since 2.20: * Made `xscreensaver-command -time' use different words.
1115 (It now describes the two states as "screen blanked
1116 since..." and "screen non-blanked since..." instead of
1117 "active since..." and "inactive since..." which a lot
1118 of people interpreted as meaning the opposite of what
1120 * Improved some error messages, in the hopes of making
1121 the distinction between the xscreensaver and
1122 xscreensaver-command programs more obvious.
1123 * Rewrote (and reorganized) parts of the xscreensaver and
1124 xscreensaver-command manual pages.
1125 * Renamed xscreensaver's `-lock' command-line option to
1126 be `-lock-mode', to avoid confusion with the `-lock'
1127 option to xscreensaver-command, which does a totally
1129 * Removed xscreensaver's `-demo' command-line option for
1130 a similar reason; use `xscreensaver-command -demo'
1132 * Disabled SGI's ``scheme'' nonsense in a better way than
1133 fully-qualifying the background colors in every single
1135 * Fixed some other minor cosmetic problems when *sgiMode
1137 * Fixed an X error in `bsod -root' (how ironic...)
1138 Changes since 2.19: * Fixed a bug that caused the mouse to sometimes not be
1139 grabbed properly (meaning the window manager menu could
1140 pop up over the demo-mode display.)
1141 * Fixed a bug that made the stderr output sometimes get
1143 * Fixed a bug that made the demo-mode scrollbar move too
1145 * Protected against a possible buffer overflow.
1146 * Made `vidwhacker' not leave stray xv windows around.
1147 * New version of `ant' so that Bagley doesn't calve.
1148 * Make configure on AIX get XShm from the right library.
1149 Changes since 2.18: * One file was missing from the tar file. Fixed.
1150 Changes since 2.17: * Oops, atlantis wasn't being built by default. Fixed.
1151 * Added `epicycle' hack.
1152 * Added `interference' hack.
1153 * Added `truchet' hack.
1154 * Added `bsod' hack.
1155 * Added some new modes to `vidwhacker'.
1156 Changes since 2.16: * Added a -window-id argument to most hacks, so that they
1157 can draw on arbitrary externally-provided windows.
1158 * Synched with xlockmore 4.11a01.
1159 * Added `flow' hack.
1160 * Added `atlantis' GL hack.
1161 * Renamed `puzzle' hack to `jigsaw', since xlock already
1162 had a different mode called `puzzle'.
1163 * Made it self-configure properly when Motif 2.1.0 is
1164 being used (requires -lXp now, sigh...)
1165 Changes since 2.15: * Made `flag' able to do XPM images.
1166 * New look for the xscreensaver logo (`xroger').
1167 * Fixed compilation error on Suns with adjunct passwords.
1168 * Got multi-architecture builds working again.
1169 * Some configure tweaks for building on HPUX and Solaris.
1170 * Fixed bug in decayscreen.

1178 * Added `stairs' hack.
1179 * Split `escher' into `cage' and `moebius', as per
1181 * Changed subprocess handling to use sigaction() instead
1182 of signal() if it's available (this is necessary for
1183 SCO but should work fine on other systems too.)
1184 * Various other tweaks.
1185 Changes since 2.13: * Better fix for the Motif drag-and-die lossage.
1186 * Put in some kludges to work around a LessTif bug.
1187 * XScreenSaver is known to work with LessTif 0.82 now.
1188 * Made fading work on high-end SGI video hardware.
1189 * Fixed another SGI-specific bug in screen grabbing;
1190 will the madness never cease?
1191 * Fixed another crash in `xlyap'.
1192 Changes since 2.12: * Made `decayscreen' do directions other than down.
1193 * Improved `puzzle'.
1194 * Fixed a crash in `xlyap'.
1195 * Added CDE info to the man page, removed `cde.txt'.
1196 * Configure tweaks for Zippy.
1197 * Turned off the signal handling in `bubbles' because
1198 it was sometimes failing to die.
1199 * Added `hacks/xscreensaver-sgigl.c' to make it possible
1200 to run SGI's ElectroPaint hack (/usr/demos/bin/ep)
1201 with xscreensaver. Finally!
1202 * Fixed a buffer overrun in the locking code that some
1203 wily, malicious cracker must have slipped in.
1204 * Disabled Motif drag-and-drool in the dialog box
1205 buttons, since it's broken in some old versions of
1207 Changes since 2.11: * Added `README.debugging'.
1208 * Added `puzzle' hack.
1209 * Added `xlyap' hack.
1210 * Added `default-n' as a visual name, so that one can
1211 have -install on by default, but turn it off for
1212 certain poorly-behaved hacks (like xv.)
1213 * Added support for grabbing frames of external video
1214 (on SGI) to the screen-grabbing hacks (decayscreen,
1215 slidescreen, slip, blitspin, and puzzle.)
1216 * Improved look of tiles in `slidescreen'; fixed its
1217 color allocation problem.
1218 Changes since 2.10: * Tweaked `blitspin', added it to the default list.
1219 * Added `lissie', `mountain', `triangle', `worm',
1220 `rotor', and `ant' from xlockmore.

1228 * Fixed compilation problem with Sun's version of OpenGL.
1229 * Added ability to use sigaction() instead of signal()
1230 to work around a SCO kernel bug.

1248 * Fixed low-color behavior of `goop', `pyro', `starfish',
1249 `greynetic', `flame', `halo', and `moire'.

1252 * Added basic dependencies to the Makefile.in files.
1253 Changes since 2.01: * Fixes for compiling with the MIT saver extension.

1255 * Various configure tweaks.
1256 Changes since 2.00: * Added `goop' and `starfish' hacks.

1259 * Added better $PATH diagnostics.
1260 * There was a bug in frand! Color selection should be
1262 Changes since 1.34: * Converted to use `configure' instead of `imake'.

1271 * Generalized sub-process management (Unix sucks!)
1272 * Added interactive mouse frobbing to Julia.
1273 * Added (untested) support for HPUX shadow passwords.
1274 * Made normal non-shadow passwords be checked if the
1275 shadow passwords aren't accessible for some reason.
1276 Changes since 1.31: * Removed *colorPrograms and *monoPrograms resources:
1277 made it possible to specify the desired visual on a
1279 * Cleaned up / restructured the driver: no more globals.
1280 * Made the Motif and Athena dialogs share more code.
1281 * Probably fixed some Athena colormap-installation bugs.
1282 * Fixed screen grabbing (cmap) on SGI 12-bit PseudoColor.
1283 * Fixed divide-by-zero in bright random colormaps.
1284 * Added an improved version of xlock's `flag' hack.

1294 themselves: it now re-blanks the screen every so often.
1295 * Added `-time' option to `xscreensaver-command'.
1296 * Improved SGI screen-grabbing some more: now it can grab
1297 TrueColor screens into PseudoColor windows and have the
1298 colors still come out semi-reasonably.
1299 Changes since 1.29: * Made `slidescreen' and `decayscreen' work better on
1300 SGIs when windows of different visuals are present, by
1301 using the XReadDisplay() extension to get a true 24-bit
1302 image out of the frame buffer.
1303 * Made `noseguy' be in color, if compiled with XPM.
1304 * Ported `braid', `drift', `fract', `galaxy', `grav',
1305 `ifs', `julia', `laser', `lightning', `penrose',
1306 `sierpinski', `slip', `spiral', and `strange' hacks
1308 * Merged `hopalong' hack with a more recent version.
1310 Changes since 1.27: * Added `deco', `moire', and `kaleidescope' hacks.
1311 * Merged in support for non-Motif locking and demo mode.
1312 * Made `blitspin' and `bubbles' work in TrueColor.

1324 than using the RNG in libc.
1325 * Made locking work on SCO.
1326 * Various other minor tweaks that I don't remember.
1327 Changes since 1.24: * Made it capture the stdout/stderr of its subprocesses
1328 and present them on the screensaver window itself.
1329 * Made demo mode work correctly with non-default visuals
1330 and color maps, instead of always using the defaults.
1331 * Added -visual argument to all included screenhacks.
1332 * Support for the R6 MIT-SCREEN-SAVER server extension.
1333 * Made the demo mode list scroll properly.
1334 * Added `pedal' hack.
1335 Changes since 1.23: * Fixed some private-colormap oddities in slidescreen,
1336 decayscreen, and xroger. Fixed apparent conservation-
1337 of-mass problem in pyro; made the shrapnel round.
1338 Changes since 1.22: * Minor tweaks for IRIX5; fixed locking race condition.
1339 Changes since 1.21: * Minor tweaks for X11R6.
1340 * Fixes for non-default visuals.

1358 minutes can be specified in seconds.
1359 * Added colormap cycling to `imsmap'.

1369 * Can use `xv' as a slideshow without using up colormap
1370 entries while the screen is not blanked.
1371 * Fixed a BadDrawable error in non-XIdle mode.
1372 * Added `blitspin' and `imsmap'.
1373 Changes since 1.0: * Current list of included hacks is now: qix, helix,
