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 4 and MacOS X 10.5

46 terminal emulator applications on MacOS.
47 * `photopile' sped up.
48 * New molecule in `molecule'.
49 * "Upgraded" to XCode 4.0, which means that MacOS 10.4

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

102 * Minor tweaks to `maze', `m6502', `hypnowheel', and
104 * Savers that load images now obey EXIF rotation tags.
105 * Arrgh, more RANDR noise! Fixes this time for rotated
106 screens, and for systems where RANDR lies and says the
108 * When the password dialog has timed out or been
109 cancelled, don't pop it right back up a second time.
110 * Password timeouts/cancels don't count as
112 * Retired some of the older, less interesting savers:
113 say goodbye to `bubbles', `critical', `flag', `forest',
114 `glforestfire', `lmorph', `laser', `lightning', `lisa',
115 `lissie', `rotor', `sphere', `spiral', `t3d', `vines',
116 `whirlygig', and `worm'.
117 * Merged `munch' and `mismunch'.

125 * Added transparency to `stonerview'.
126 * Improved layout of the preferences dialogs: they
127 should all now be usable even on ridiculously tiny
129 * MacOS preferences text fields now prevent you from
130 entering numbers that are out of range.
131 * Added "Reset to Defaults" button on X11.
132 * Added relevant Wikipedia links to many of the screen
134 * All hacks support the `-fps' option, not just GL ones.
135 * The `-fps' option now shows CPU load.
136 Changes since 5.05: * Xinerama/RANDR fixes: this time for sure. It should
137 now work to add/remove monitors or resize screens at
139 * New hack, `skytentacles'.
140 * New version of `gleidescope'.
141 * Added the `-log' option to the xscreensaver daemon,
142 since a truly shocking number of Linux users seem to
143 have no idea how to redirect output to a file.
144 * Added `-duration' arg to most image-loading hacks,
145 so that they pick a new image every few minutes.
146 * Added an ATM crash to BSOD.
147 Changes since 5.04: * New hacks, `cubicgrid', `hypnowheel', and
148 `lcdscrub' (which isn't really a screen saver).
149 * Updates to `m6502' and `gears'.
150 * Fixed double-buffering problems in `cubestorm' and
152 * Better handling of horizontal scroll wheels.
153 * Attempt to work around latest Xinerama braindamage:
154 if the server reports overlapping screens, use the

159 text-displaying hacks to fail on some systems.
160 * Hopefully fixed font-related System Preferences crashes
162 * The recent PAM changes broke the "Caps Lock" warning
163 in the password dialog, the failed login warnings, and
164 syslogging. Fixed all that.
165 Changes since 5.03: * Fixed a possible crash in the unlock dialog (more
166 fallout from the recent PAM changes...)
167 * New hacks, `moebiusgears', `abstractile', and
169 * Rewrote `gears' to use better (involute) gear models,
170 and to be more random.
171 * Minor updates to `cwaves', `voronoi', `deco',
172 `glcells', `rd-bomb', `fireworkx' and `webcollage'.
173 * `pong' can now display the current time as the score.
174 * `xmatrix -mode pipe' works better.

188 `flipflop', `flipscreen3d', `fliptext', and `carousel'.
189 * Enabled multi-threaded OpenGL on MacOS.
190 Changes since 5.00: * Backed out recent locale-related changes, since they
191 broke far more things than they fixed.
192 * Fail gracefully with ridiculously small window sizes.
193 * `xflame' and `flag' ignore bitmap option on MacOS.
194 * `speedmine' prefs work on MacOS.
195 * Better explosions in `boxed'.
196 * More dynamic motion in `sproingies'.
197 * More options in `flipflop'.
198 * Minor updates to `topblock'.
199 * Various other minor fixes.
200 Changes since 4.24: * Ported to MacOS X! (10.4.0 or newer)
201 * API change: instead of providing a single screenhack()
202 function that does not return, screen savers using the
203 screenhack.h framework must now provide "init" and
204 "draw one frame" functions instead. All bundled savers
205 have been updated; third-party patches will need work.
206 * All image-loading happens asynchronously.
207 * xscreensaver-getimage-file caches the contents of the
208 image directory for a few hours, so consecutive runs
209 won't have to re-list the whole directory tree.
210 * New hacks, `topblock' and `glschool'.
211 * Removed `xteevee' (superceded by `xanalogtv').
212 * Added variable-sized puzzle pieces to `jigsaw'.
213 * Changes to the defaults and command-line options of
214 many hacks to make the .xml files more consistent.
215 * Reap zombies in `glslideshow' and `carousel'.
216 * `sonar' works without setuid on MacOS (dgram icmp).
217 * `xmatrix -mode pipe' displays the text of a subprocess.
218 * `endgame' has higher resolution chess-piece models.
219 * `webcollage' takes a -directory option to get images
220 from a local directory.
221 * The RPM spec file no longer auto-restarts xscreensaver
222 when a new version is installed. Restart it manually.
223 Changes since 4.23: * New versions of `cube21', `glsnake', `celtic'.
224 * Backed out a DPMS-related patch that cause desktop
225 flickering with some X servers.
226 * Fixed startup crash in getgroups() when running setuid.
227 * Default to not displaying stderr on the saver window.
228 * Fixed bad free() in "Documentation" button.
229 * Don't try to run hacks that aren't installed.
230 * Minor fixes to various XML config files and man pages.
231 Changes since 4.22: * New hacks, `glhanoi', `cube21', `timetunnel',
232 `juggler3d', and `celtic'.
233 * New versions of `tangram', `webcollage', `hypertorus',
234 `polytopes', and `ripples'.
235 * `sonar' is now quiet about unresolvable hosts.
236 * Minor corrections to BASIC code in `apple2'.
237 * xscreensaver-demo now provides an RPM clue when none
238 of the hacks seem to be installed.
239 * Don't install `ant' by default, since there is some
240 Java tool of that name, which was causing confusion.
241 And also it's boring.
242 * Made screen grabbing work again on MacOS 10.4.2.
243 * No longer prints bogus warnings about ClientMessages
244 intended for the window manager.
245 * Ignore unprintable characters in passwd entry field.
246 * Fixed yet another cross-host-display image-loading
248 * `xscreensaver-command -watch' and `-time' now work
250 Changes since 4.21: * Fixed a bug in the new mouse-motion code that caused
251 the screen to never blank on multi-head non-Xinerama
253 * New hacks, `interaggregate', `antmaze', `tangram',
255 * Minor tweaks to `fiberlamp', `ifs', `slidescreen',
256 `zoom', `sonar', `fireworkx', `whirlwindwarp',
257 `bubble3d', and `rd-bomb'.
258 * Added motion blur to `blinkbox'.
259 * `bsod' now includes Longhorn's "RSOD", and OS/2.
260 * Fixed `-wireframe' usage in most hacks and man pages.
261 Changes since 4.20: * New hack: `fliptext'.
262 * Changed default configure installation directories:
263 /usr/bin/ for xscreensaver, etc.;
264 /usr/libexec/xscreensaver/ for hacks;
265 /usr/share/xscreensaver/config/ for xml files.
266 * All the text-manipulating screen savers can have their
267 text source configured via `xscreensaver-demo' now.
268 * xscreensaver.spec now builds three RPMs:
269 base (no hacks); extras (2d hacks); and gl-extras.
270 * Added `-program' and `-front' option to `gltext'.
271 * Added `-shells' to `molecule'.
272 * Fixed text-alpha glitch in `carousel'.
273 * New `pacman': the ghosts can be killed now.
274 * Fixed a bug in screen-grabbing GL hacks where images
275 would be tiled instead of scaled on machines that
276 can't do large textures.
277 * `webcollage' can hit Flickr now.
278 * New (rewritten) implementation of `ifs'.
279 * The unlock dialog can be made to have a "New Login"
280 button that will run `gdmflexiserver'. Experimental!
281 * Fixed non-ASCII display bug in `starwars'.
282 * Configure finds a default for imageDirectory.
283 * "xscreensaver-command -lock" now works even if
284 in "screensaver disabled" mode.
285 * If a bad password is typed while CapsLock is on, the
286 unlock dialog says "CapsLock?" instead of "Sorry".
287 * Mouse motion only counts as activity if the mouse moved
288 more than 10 pixels (so the screen won't unblank every
289 time you bump your desk.)
290 * New mode option "random-same": if you have multiple
291 monitors, this will run the *same* randomly chosen
292 hack on each screen, instead of different ones on each.
293 Changes since 4.19: * New hacks, `fiberlamp', `boing', `boxfit', and
295 * Rewrote `glslideshow' again: should be faster now.
296 * Sped up loading of images in GL programs.
297 * `starwars' uses texture-mapped fonts now.
298 * New `bsod' modes: tru64, hppa, and nvidia.
299 * Updates to `webcollage', `juggle', `pinion',
300 `fireworkx', `sonar', `extrusion', `substrate', and
302 Changes since 4.18: * New hacks, `substrate', `intermomentary', `fireworkx',
304 * New version of `flow'.
305 * Made /proc/interrupts work again on Linux 2.6.
306 * Made `analogtv' not hog the CPU.
307 * Made analogtv-based hacks work properly on PPC/ARM.
308 * Fixed a bad memory leak in `piecewise'.
309 * Minor updates to `sonar', `molecule', `glmatrix',
310 `galaxy', and `webcollage'.
311 * Removed support for GTK 1.x (everyone uses 2.x now.)
312 Changes since 4.17: * Oops, pay no attention to the man behind the curtain.
313 Changes since 4.16: * New hacks, `anemotaxis' and `memscroller'.
314 * Fixed a bad bug that caused `vidwhacker' to never die.
315 * Fixed normals and lighting in `polyhedra'.
316 * Don't reuse the window when changing hacks (to work
317 around bugs in some GL implementations.)
318 * Made `xscreensaver-getimage-file' skip thumbnail-sized
320 * Fixed endian problem in `barcode' on non-x86.
321 * Updates to `webcollage', `apple2', `fuzzyflakes',
322 `atunnel', and `pacman'.
323 * Timing tweaks to `bubble3d', `bouncingcow', `engine',
324 `gltext', `lavalite', `molecule', `spotlight',
325 `sballs', `boxed', `blinkbox', and `circuit'.
326 * Configure updates for Fedora core 2 / xorg 6.7.0.
327 * Compile without warnings under gcc 3.3.3.
328 * I give up: don't blank or lock the screen if we can't
329 get a keyboard grab. In that case, both choices are
331 Changes since 4.15: * New hacks, `polyhedra', `fuzzyflakes', `antinspect',
333 * Minor updates to `webcollage', `bsod', `endgame',
334 `antspotlight', `xmatrix', and `glmatrix'.
335 * Added support for the RANDR (Resize and Rotate)
336 extension to detect when the size of the desktop has
337 been changed while xscreensaver is already running.
338 * Possibly-futile attempt to work around "rdesktop"
340 * Made `xscreensaver-getimage -file' still work even if
341 imageDirectory is unset.
342 * Convert Latin1 to ASCII in `starwars' and `phosphor'
343 (since the GLUT font only has ASCII glyphs.)
344 * Fixed randomization in `noof'.
345 * Added "GetViewPortIsFullOfLies" preference to work
346 around longstanding XFree86 bug #421.
347 * Made `sonar' subnet pinging work properly on bigendian
348 machines (e.g., PPC.)
349 Changes since 4.14: * New hacks, `wormhole', `mismunch', `noof', and
351 * `phosphor' and `apple2' include vt100 emulators now:
352 this means you can do "phosphor -program top", or
353 can use either program as an xterm replacement:
354 "apple2 -text -fast -program 'xemacs -nw'".
355 * `analogtv' (and related) fill the screen better.
356 * The '-gradient' option works in `atlantis' now.
357 * Minor updates to `blinkbox', `queens', `endgame',
358 `glmatrix', `mirrorblob', `blocktube', and `molecule'.
359 * Integrated SuSE's "external passwd helper" support.
360 * Marginally better /tmp handling in various programs.
361 * Updated config defaults for xplanet 1.0.3.
363 Changes since 4.13: * New hacks, `fontglide', `apple2', `xanalogtv', `pong',
364 `gleidescope', `mirrorblob', and `blinkbox'.
365 * New version of `glsnake' (with many more models.)
366 * Another Windows crash in `bsod'; also HVX/GCOS6/TPS6.
367 * New version of `endgame'.
368 * Screen grabbing works on MacOS X.
369 * Various minor fixes.
370 Changes since 4.12: * On Xinerama systems, xscreensaver now runs one hack on
371 each monitor (just like in "real" multi-head mode)
372 instead of running one hack stretching across all the
373 screens. Note that for this to work with any 3rd party
374 screensavers, they must update their "vroot.h" file.
375 * `webcollage' and `vidwhacker' display images using
376 `xscreensaver-getimage' now.
377 * Added `ljlatest' script for use with `starwars' and
379 Changes since 4.11: * New GL hacks, `flipflop', `antspotlight', and
381 * Added VMS to `bsod'.

386 `blocktube', and `glmatrix'.
387 * Updates to `cloudlife', `engine', `xmatrix', and
389 * Rewrote `glslideshow': it should work on somewhat
390 wimpier video cards now.
391 * Various portability tweaks.
392 Changes since 4.09: * New hacks, `cloudlife' and `klein'.
393 * Added Apple ][+, HPUX, and OS/390 sessions to BSOD.
394 * Added some Matrix Reloaded text to `xmatrix'.
395 * Updates to `webcollage', `eruption', `jigglypuff',
396 `metaballs', and `endgame'.
397 * Completely ignore the `memoryLimit' setting now,
398 since it was still causing people GL grief.
399 * Various minor fixes.
400 Changes since 4.08: * New hacks, `flyingtoasters', `bouncingcow',
401 `jigglypuff', and `glslideshow'.
402 * More models in `engine'.
403 * Rewrote `xscreensaver-getimage' to remove reliance on
404 external image loaders (xv, chbg, xloadimage, etc.)
405 and to reduce flicker when loading files.
406 * Made `gflux' and `flipscreen3d' be mouse-spinnable.
407 Changes since 4.07: * New hacks, `atunnels' and `piecewise'.
408 * Physics improvement in `fluidballs'.
409 * Various fixes for XDarwin systems (X11 on MacOS X.)
410 * Added -clock option to `barcode'.
411 * Minor fixes to `endgame', `flurry', `flipscreen3d',
413 Changes since 4.06: * New hacks, `flurry', `metaballs', `eruption',
414 `popsquares', and `barcode'.
415 * Minor updates to `maze' for high density mazes.
416 * Added double buffering to `fluidballs' and `whirlygig'.
417 * Bug fixes for running xscreensaver to a remote XFree86
418 display (which nobody would ever do...)
419 * Updated `webcollage' (faster Alta Vista searching.)
420 * Updated `glplanet' so the sun sets in the west.
421 * Updated `sproingies' with smooth, unsegmented surfaces.
422 * Fixed Perl version-sensitivity in
423 `xscreensaver-getimage-file'.
424 * Fixed GTK2 scrolling bug in `xscreensaver-demo'.
425 Changes since 4.05: * New hack, `glblur' (disabled by default, since it
426 requires fast OpenGL texture support.)
427 * New hack, `halftone'.
428 * Updates to `endgame', `queens', `bumps', `glplanet',
429 `engine', and `circuit'.
430 * New version of `menger' that uses far fewer polygons.
431 * Fixed minor bug in `critical' that could cause some
432 bogus X servers to crash.
433 * Better labels in `molecule': the labels now appear to
434 be attached to the atoms, instead of floating in front
436 * Fixed bug that could rarely cause GL hacks to fail to
437 double-buffer (causing intermittent flickering.)
438 * Fixed a relative-URL-parsing bug in `webcollage'.
439 * Fixed a bug that (sometimes) caused the window manager
440 close box to kill `xscreensaver-demo' with a crash
441 instead of a graceful exit.
442 * Updated xscreensaver.pam to the Red Hat 7.3 way.
443 * More Gnome2-related configure crap.
444 * Updated to latest `config.guess' and `config.sub'.
445 * Fixed occasional core dump in `distort'.
446 * Added a Linux fsck failure and kernel panic to `bsod'.
447 * Added MacOS X kernel panic to `bsod'.
448 * Fixed a bug in `bsod' (all bsod bugs are ironic.)
449 * Fixed a bug that caused `xscreensaver-gl-helper' to
450 print a nonsense visual ID with some versions of
451 `printf': this could cause GL programs to display
452 incorrectly (e.g., flickery.)
453 Changes since 4.04: * More `configure' tweaks to try and get things working
454 on systems that both Gtk 1.x and 2.x installed.
455 * New hack, `endgame'.
456 * Minor updates to `gltext'.
457 Changes since 4.03: * Support for GTK 2.x / GNOME 2.x.
458 * The `configure' script will now use `pkg-config' if
459 you have it, in preference to `gtk-config', etc.
460 * New hacks, `lavalite', `queens', and `anemone'.
461 * Minor updates to `spheremonics', `gltext', `xmatrix'.
462 * You can use the mouse to manually spin most of the GL
463 hacks now (when they are displaying in a window.)
464 * Fixed a bug in `webcollage' (due to recent Alta Vista
465 url changes) that was causing it to try and load
466 incorrect image URLs.
467 * Made `xscreensaver-getimage' use gdk_pixbuf if it is
468 available: this means that those hacks that load images
469 will no longer rely on "xv", "xloadimage", etc. This
470 will close a race condition that could sometimes cause
471 your desktop background to be changed; and also makes
472 it possible for those programs to operate on image
473 files when running in windowed mode.
474 * `webcollage' can now be used in conjunction with
475 `driftnet' to display images snooped from your local
476 ethernet instead of obtained from search engines.
477 * Added man pages for all the hacks that didn't have
479 Changes since 4.02: * New hack, `spheremonics'.
480 * Minor updates to `webcollage', `cage', `moebius',
481 `morph3d', `boxed', `circuit', and `helix'.
482 * `pulsar' and `extrusion' can now load texture JPEGs.
483 * `rubik' now does non-square cubes.
484 * `fluidballs' now does various sizes of balls.
485 * `menger' and `sierpinski3d' now also show polygon
487 * `molecule' displays real subscripts in the formulae.
488 * GTK internationalization/localization support.
489 * Better detection of the various versions of libxml.
490 * Upgraded to autoconf 2.53 (from 2.13.)
491 Changes since 4.01: * Plugged a few minor leaks in `xscreensaver' and
493 * New hacks, `cubenetic' and `fluidballs'.
495 * Fixed sphere projection error in `glplanet'; installed
496 a better image of earth.
497 * Added Win2K and MacOS 1 crashes to `bsod'.
498 * Put back previous (better) version of `forest' that
499 was accidentially downgraded in the last release.
500 * New version of `bumps'.
501 * Made FPS computation in GL hacks more efficient: it
502 will influence the results less, thus resulting in
503 higher (but more accurate) reported frame rates.
504 Changes since 4.00: * New hacks: `twang', `glsnake', `boxed', `sballs',
506 * New hacks `apollonian', `euler2d', `juggle',
507 `polyominoes' and `thornbird', from xlockmore.
508 * Merged recent xlockmore changes into `ant', `braid',
509 `demon', `discrete', `drift', `fadeplot', `forest',
510 `grav', `hopalong', `ifs', `laser', `lightning',
511 `lisa', `lissie', `loop', `mountain', `penrose',
512 `rotor', `sierpinski', `slip', `sphere', `spiral',
513 `strange', and `vines'.
514 * Fixed the `gltext' bug that sometimes caused
515 horizontal lines to vanish again. This time for sure.
516 * Sped up `webcollage' by adding a C helper program to
517 replace the PPM pipeline. It also pastes images
518 semi-transparently now.
519 * Added support for the gdk_pixbuf library: if this lib
520 is available, then `blitspin', `xflame', and `flag'
521 can load GIF, JPEG, and PNG images in addition to XPM
523 * Fixed a rare race condition where the desktop-grabbing
524 hacks could sometimes leave the screen wedged, if the
525 user moved the mouse exactly when they were grabbing
526 the screen image (it would un-wedge the next time the
527 saver timed out or was activated.)
528 * Fixed incorrect colors in the screen-grabbing GL hacks
529 (`gflux' and `flipscreen3d'.)
530 * Made SIGHUP restart the daemon process (though using
531 `xscreensaver-command -restart' is still the preferred
533 * Tweaks to `xspirograph'.
534 * Minor configure and portability tweaks.
535 Changes since 3.34: * Redesigned `xscreensaver-demo' GUI: it now includes
536 small-preview and per-hack configuration dialogs.
537 * Added three new modes of operation: `One Screen Saver',
538 `Blank Screen', and `Don't Blank' (in addition to the
539 historical `Random Screen Saver').
540 * Configure now defaults to installing the hacks in
541 <prefix>/lib/xscreensaver/ instead of <prefix>/bin/.
542 (Most distros already did it this way.)
543 * New GL hacks, `menger', `engine', `flipscreen3d'.
544 * Made `sierpinski3d' be more colorful.
545 * New versions of `xmatrix' and `nerverot'.
546 * Fixed a bug in `starwars' that made the font be drawn
547 with thin lines in -root mode.
548 * Fixed a bad colormap bug in `crystal' that could make
549 *subsequent* hacks malfunction!
550 * Made `gflux' able to grab screen images (`-mode grab').
551 * Updated `webcollage' for recent search engine changes.
552 * Removed most command-line options to `xscreensaver':
553 just edit the ~/.xscreensaver file instead.
554 * Improved behavior on multi-screen and Xinerama systems:
555 the mouse now stays on the screen where the user left
556 it, and the password and splash dialogs always appear
557 on the screen that has the mouse.
558 * Made the splash dialog use more Gtk-like colors;
559 made it have only two buttons, "Settings" and "Help".
560 * Made `sonar' understand `.ssh/known_hosts2' format
561 files, and be better about stripping out illegal
563 Changes since 3.33: * Turned `memoryLimit' off by default, sigh. Apparently
564 some versions of the GL libraries (appear to) allocate
565 hundreds of megs for every GL program, so `memoryLimit'
566 was causing GL programs to malfunction or crash on
568 * Improved fading on TrueColor XFree86 4.1.x systems.
569 * New GL hack, `circuit'.
570 * Added `fuzz' mode to `decayscreen'.
571 * New version of `whirlygig'.
572 * Added links to `xplanet' and `sphereEversion'.
573 * Fixed rare race condition that could make `sonar' hang.
574 * Fixed potential crash in `speedmine'.
575 * Made `xscreensaver-demo' not crash when imageDirectory
576 was set to a non-existent directory.
577 * Made `xscreensaver-getimage-video' invoke XawTV's
578 `streamer' program better.
579 * Made `phosphor' and `starwars' deal with CR, LF,
580 or CRLF line endings.
581 * Changes for Cygwin compilation environments.
582 * Made `sonar' compile on systems that can't ping.
583 * Configure changes for HPUX 10.20.
584 * Made PAM code work on Red Had 4.2 systems.
585 * Made `xscreensaver-command -deactivate' work when the
586 saver is not active: what that does is reset the idle
587 timer, as if keyboard input had been detected. This
588 was added for the benefit of people writing DVD-playing
589 software: they can now prevent the screensaver from
590 kicking in by sending a -deactivate message once a
591 minute while the movie is playing and not paused.
592 * Various minor portability tweaks.
593 Changes since 3.32: * New hacks, `speedmine' and `whirlygig'.
594 * Sped up `pyro', made the explosions look a bit better.
595 * Added better stars to `glplanet' and `starwars'.
596 * Many internal changes to `webcollage'.
597 * Some new options to `attraction'.
598 * Minor fix to `noseguy' to avoid un-erased pixels.
599 * Rewrote the screen-eraser effects so that they complete
600 in the same amount of time regardless of how slow
601 your X server is (some of them were glacial on servers
603 * Fixed a potential free memory reference that could
604 sometimes cause a crash at startup.
605 * Possibly fixed a problem that could cause the daemon
606 to crash with an X error. I was never able to
607 reproduce this problem, but I think I might have
608 figured out what caused it.
609 * Worked around a problem that caused PAM authentication
610 to fail on some Red Hat 7.x systems.
611 * Added a `memoryLimit' parameter that controls the
612 amount of memory a graphics hack may allocate: if they
613 try to allocate more than this, malloc() will fail
614 (and they will exit or (safely) crash, rather than
615 hogging memory.) Default is 50M.
616 * Made `gnome-help-browser' be the default way to display
617 man pages in `xscreensaver-demo', if running on a
619 Changes since 3.31: * The image-manipulating hacks (`slidescreen', etc.) can
620 now operate on randomly chosen image files from disk,
621 or on frames captured from the system's video input,
622 instead of (or in addition to) manipulating images of
624 * Rewrote `vidwhacker' to use the new image-grabbing
626 * Made fading work on TrueColor XFree86 4.x systems.
627 * Fixed a subtle rendering bug in `atlantis' (the fish
629 * Made `atlantis' have a texture simulating light
630 reflections from the surface of the ocean.
631 * Fixed up label placement in `molecule'.
632 * Better color bars in `xteevee'.
633 * Made `install-strip' not try to strip scripts.
634 Changes since 3.30: * Put in more sensible defaults for DPMS, and updated
635 the documentation to reflect the fact that all your
636 DPMS settings are now belong to xscreensaver.
637 * Fixed the `xscreensaver.spec' file so that `--force'
639 * New versions of `rotzoomer' and `nerverot'.
640 * Fixed an OSF/1 compilation problem in `molecule'.
641 Changes since 3.29: * New hacks, `molecule', `dangerball', and `rotzoomer'.
642 * New version of `gflux'.
643 * Made `gltext' able to display the current time.
644 * Fixed a floating-point-precision problem in `gltext'
645 that sometimes caused horizontal lines to vanish.
646 * Removed the `-window-id' option from the hacks:
647 it never worked right, and was unnecessary.
648 * Made the `starwars' hack use thicker lines, antialias
649 the text, and fade out at the far edge instead of just
651 * Fixed an SHM segment leak in `moire'.
652 Changes since 3.28: * Better rendering of the new logo.
653 * New hack, `gltext'.
654 * Added `-planetary' option to `gears', to draw a
655 different kind of gear system.
656 * Made motion and rotation be smoother in `gears',
657 `glplanet', `moebius', `rubik', and `sierpinski3d'.
658 * Improved coloration in `sierpinski3d'.
659 * Made the GL hacks react to window size changes.
660 * Made most of the GL hacks take a -fps option (like
661 `pulsar' did), so you can use them to benchmark your
663 * Fixed the previous fix to `sonar'.
664 * Minor fix to `nerverot'.
665 Made sonar able to ping hosts on DEC OSF1.
666 * Eliminated a bogus "didn't get enough colors" warning
667 in some of the hacks.
668 Changes since 3.27: * New logo for xscreensaver!
669 * New hacks, `starwars' and `stonerview'.
670 * Made the motion of the bouncing ball in `stairs' be a
672 * Made newly-added screenhacks be added to .xscreensaver
673 automatically: if there are hacks in the app-defaults
674 file that are not also in ~/.xscreensaver, they will
675 be added to the end of the list.
676 * Redid the `Screensaver Options' part of the control
677 panel; xscreensaver now lets you configure your DPMS
679 * Fixed some Makefile problems with non-GL builds.
680 * Fixed detection of MesaGL for version 3.3.
681 * Better workaround to Red Hat 7.0's broken gcc.
682 * Added Sparc Solaris kernel panic to `bsod'.
683 Changes since 3.26: * New hacks: `zoom' and `whirlwindwarp'.
684 * Fixed a free-memory-reference bug in `sonar'.
685 * Better error handling when there are no suitable GL
687 * Added diagnostic dialog when xscreensaver-demo is
688 unable to launch xscreensaver (e.g., when running as
690 * Fixed a bug that caused screenhack argument changes
691 to be ignored when xscreensaver-demo was running as
692 root (if "root" and "nobody" have different home
694 * Made the programs default to ":0" if $DISPLAY is unset.
695 * Made the `-verbose' output include information about
696 which server extensions were supported at compile time.
697 * Worked around Red Hat 7.0's broken gcc 2.96.
698 * Updated default delays on the GL hacks to look better
699 on machines with super-fast 3D hardware.
700 * Install `screensaver-properties-capplet' to work around
701 the usual egregious GNOME lossage.
702 Changes since 3.25: * Added "enabled" checkboxes in the list of hacks in
703 xscreensaver-demo (Gtk version only.)
704 * New hacks `hyperball', `xrayswarm', and `gflux'.
705 * New versions of `nerverot', `galaxy', and `hypercube'.
706 * Small fixes to `phosphor', `shadebobs', `xflame',
708 * Added external helper program `xscreensaver-gl-helper'
709 to figure out which X visual to use for OpenGL
711 * Configure updates for XFree86 4.0, and for BSD.
712 * Made it be more tolerant of bogus /etc/group files.
713 * When installing the PAM config file, first try to just
714 copy an existing "xdm" or "login" config file, so that
715 xscreensaver does authentication in the same way as the
717 Changes since 3.24: * New hack, `nerverot'.
718 * Added BSD kernel panic to `bsod'.
719 * New version of `shadebobs'.
720 * New version of `petri'.
721 * Updated `webcollage' to handle recent Altavista URL
722 format changes; made it search the AP photo gallery.
723 * Revamped command-line options of `sonar' and made it
724 properly handle subnets.
725 * The `bubbles' hack can now trickle up or down the
727 * The `xsublim' hack can now read its text from programs.
728 * Support for GLE version 3 in `extrusion'.
729 * Fixed compilation problems in `maze'.
730 * Fixed a rare crash in `flow'.
731 * Fixes for minor installation problems.
732 Changes since 3.23: * Added `-ignorant' option to `maze' hack.
733 * Updates to `critical', `bsod', `xflame', and `flow'.
734 * Added support for Kerberos 5 (via its Kerberos 4
735 compatibility layer.)
736 * Fixed a bad leak in `xteevee'.
737 * Updated `webcollage' to handle recent Altavista URL
739 * Removed xscreensaver-demo's `Ok' and `Cancel' buttons,
740 since they were confusing people: all changes are now
742 * Made xscreensaver-demo install itself into the Gnome
744 Changes since 3.22: * Fixed some misplaced text fields in the Motif version
745 of xscreensaver-demo; fixed a crash in the Gtk version
746 that would happen if the programs list was empty.
747 * Fixed a recently-introduced bug in `pulsar'.
748 * Made `sierpinski3d' use solid tetrahedrons instead of
750 * Added `-trace' option to `xmatrix'.
751 * Added new hacks `xteevee' and `xspirograph'.
752 Changes since 3.21: * Fixed some bugs in xscreensaver-demo.
753 * Rewrote the Motif version of xscreensaver-demo to
754 match the new Gtk version.
755 * The Athena toolkit is no longer supported.
756 Changes since 3.20: * Tweaked the xscreensaver-demo UI (Gtk only.)
757 * Fixed a few visual selection bugs. I think the proper
758 GL visual should be used with nVidia systems now.
759 * Made the Makefiles obey $install_prefix.
760 * Made the `xscreensaver.spec' file able to generate both
761 GL and non-GL packages simultaneously.
762 Changes since 3.19: * Added new hacks `ripples' and `sierpinski3d'.
763 * Made `xscreensaver-command -exit' be silent when no
764 screen saver was running (instead of complaining.)
765 * Made `webcollage' and `vidwhacker' use `xloadimage'
766 when available (in addition to `xli' and `xv'.)
767 * Improved memory usage in `petri' and gave it a hard
768 cap on how much memory it can allocate.
769 * Added `-watch' option to `xscreensaver-command'.
770 * Made `xscreensaver-demo' come up with the
771 most-recently-run hack selected by default.
772 * Rewrote the Gtk version of `xscreensaver-demo'.
773 It's a lot easier to use now.
774 * Extended the format of the programs list in the
775 .xscreensaver file, for the benefit of the new
776 capabilities of `xscreensaver-demo'.
777 NOTE: you might want to delete your ~/.xscreensaver
778 file and allow it to be re-created! The old one
779 should still work, but xscreensaver-demo won't be as
781 Changes since 3.18: * Fixed gcc dependencies in `bumps' and `ccurve'.
782 * New hack, `extrusion'.
783 * Some of the web sites that `webcollage' was using as
784 its sources changed formats; tweaked it to understand
786 * Added typeahead in the password dialog: if the screen
787 is locked, and you unlock it by typing a character,
788 that key will be automatically inserted in the
789 password dialog (unless it is Return, Enter, Space,
790 or a non-printing key like Shift.)
791 * Made `xmatrix' take a `-small' option, since some
792 folks with tiny screens prefer a smaller font.
793 Changes since 3.17: * New versions of `shadebobs', `lmorph', and `distort'.
794 * Added `ccurve', `blaster', and `bumps' hacks.
795 * Replaced `forest' hack with a rewritten version.
796 * Worked around a Xinerama server bug.
797 * Fixed a bug I introduced in 3.10 that caused some
798 hacks to print out superfluous warnings about not
799 having gotten enough colors.
800 * Made `sproingies' obey the `-delay' option.
801 * Fixed a portability bug in `shadebobs'.
802 * Made `webcollage' and `vidwhacker' use `xli' in
803 preference to `xv', if it is available.
804 * Added a new source of images to `webcollage'.
805 * If running under KDE, xscreensaver will add itself to
806 KDE's list of screensavers (via xscreensaver.kss.)
807 * Improved detection of GL libraries.
808 * Made the password dialog include the date and time.
809 Changes since 3.16: * New version of `webcollage' -- deals better with
810 corrupted images, and can use an http proxy.
811 * New hack, `xsublim' (run it in the background,
812 rather than adding it to the programs list.)
813 * The xscreensaver daemon was leaking a file descriptor
814 each time you edited your .xscreensaver file. Fixed.
815 Changes since 3.15: * New version of `shadebobs'.
816 * Improved image selection in `webcollage', and sped it
818 * Made configure find the right version of perl.
819 * Rewrote the CGI part of `webcollage'.
820 * `make clean' was deleting some things it shouldn't.
821 * Fixed a typo in the default programs list.
822 Changes since 3.14: * Added `webcollage' and `shadebobs' hacks.
823 * Added a `-stdout' arg to `vidwhacker' so that it can
824 be used in a pipeline.
825 * Made `petri' use less memory.
826 Changes since 3.13: * Various improvements to the Gtk port.
827 * Turned off PAM by default on Solaris, since PAM seems
828 generally to be misconfigured out-of-the-box.
829 * Made the `--without-gtk' configure option work.
830 * Made configure check the Gtk version number, since it
832 * Fixed a bug in the code that attempted to prevent
833 changes of screen resolution while the screen is
835 * Fixed a race condition in `xscreensaver-demo' that
836 could cause an X error at startup.
837 * Added `-transparent' option to `deluxe'.
838 * Added `petri' hack.
839 Changes since 3.12: * Ported `xscreensaver-demo' to Gtk.
840 * Made it possible to build Motif, Gtk, and Athena
841 versions of `xscreensaver-demo' in the same directory
842 without reconfiguring.
843 * Made `xscreensaver-demo' chase symlinks before writing
844 the .xscreensaver file, so that if .xscreensaver is
845 itself a symlink, the underlying file will be replaced
847 * Some Makefile and configure tweaks for Solaris and
849 * Made it possible to set the fire color in `xflame'.
850 * Made transparency work in TrueColor (for `goop' and
852 * Fixed a multi-head bug introduced by the virtual
854 Changes since 3.11: * Made it so that you can't scroll the screen while the
855 lock dialog is up (with XFree86 virtual viewports.)
856 * Fixed a bug in `flag' that caused bob's chin to get cut
857 off after a few iterations.
858 Changes since 3.10: * Made `xjack' be black-on-white-ish, so that it looks
859 less like a computer screen and more like the
860 typewritten paper it's supposed to be.
861 * New version of `pulsar'.
862 * Fixed Solaris compilation problem in `phosphor'.
863 * Made xscreensaver notice XFree86's virtual root window
864 hack, so that if the X server's root window is larger
865 than the monitor's displayable resolution, the screen
866 saver will limit itself to the area that actually
867 appears on the screen.
868 * Made the xscreensaver daemon do a better job of
869 picking the visual class that should be used for GL
870 programs. Less user intervention should be needed
871 now: you can use the logical visual name `GL' instead
872 of having to figure out by hand which one to use.
873 * Oops, the visual was defaulting to "best" instead of
874 "default", because the .xscreensaver file was not being
875 loaded quite early enough.
876 * Made configure figure out how to build icmp ping
877 support into the `sonar' hack automatically.
878 * Made warnings about not being able to read shadow
879 passwords not be printed if compiled with PAM support.
880 * Improved PAM startup diagnostics.
881 * Worked around the Solaris PAM bug that was causing
882 crashes there, so now PAM is turned on by default.
883 * Made configure detect the number of arguments that
884 pam_strerror() takes, since on Linux, this apparently
885 changed between 2.0 and 2.2, sigh.
886 * Made the /proc/interrupts kludge look for "PS/2 Mouse"
887 as well as "keyboard".
888 * Made xscreensaver notice when there has been a sudden
889 large jump in wall-clock time, and if so, lock right
890 away, instead of waiting for "lockTimeout" to expire
891 first. (Laptops need this for safer recovery from
893 * Added `-throttle' option to `xscreensaver-command'.
894 Changes since 3.09: * Added `phosphor', `xmatrix', and `pulsar' hacks.
895 * Fixed a bug in the color allocator that sometimes
896 caused `starfish' to fall back to monochrome.
897 * Reduced the amount of code that runs before root
898 privileges are disavowed: "normal" and "shadow"
899 passwords now do some initialization as root, but the
900 PAM and Kerberos authorization schemes will be
901 initialized while running as "nobody". Supposedly
902 this closes a potential security hole when using
904 * Added some more sanity checking to configure.
905 Changes since 3.08: * Added `compass', `squiral', `xflame', `wander',
906 `spotlight', and `critical' hacks.
907 * Added some new modes to `decayscreen'.
908 * Made `deluxe' work in monochrome.
909 * Generalized usage of the Double-Buffer server extension
910 in several hacks (`compass', `deluxe', `interference',
911 `kumppa', and `moire2'.)
912 * Fixed another visual-depth problem in `rd-bomb'.
913 * The screen saver will now defer blanking if neither
914 the keyboard nor the mouse could be grabbed. Instead,
915 it will just try again in a few minutes. This fixes
916 a bad interaction between xscreensaver and programs
917 like VMware that hold the mouse and keyboard grabbed
919 * Added a new erase mode (expanding spiral.)
920 Changes since 3.07: * Fixed some bugs in my port of `t3d'.
921 * Added `penetrate' and `deluxe' hacks.
922 * When linking against Motif 2.x, also link against XPM.
923 * Added support for using /proc/interrupts for idle
924 detection on Linux. Now xscreensaver shouldn't kick
925 in when the user is active on a non-X virtual console.
926 * Upgraded to autoconf 2.13.
927 Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
928 in properly; check for _Xsetlocale in -lXintl.)
929 * Portability fixes for sonar.c.
930 * Fixed a compilation problem when you have GL but don't
932 * Made configure notice when MesaGL requires -lpthread.
933 * Made `flame' ignore SIGFPE (not sure if this is the
934 right fix; it seems only to be needed on FreeBSD.)
935 * Kludged `rd-bomb' work on visuals that are of depth 24
936 but that *do not* support pixmaps of depth 32.
937 * Fixed `halo' to work properly in TrueColor.
938 * Changed `xscreensaver.spec' to install the hacks in
939 /usr/X11R6/lib/xscreensaver/ by default, since that's
940 where recent Red Hat distributions put them.
942 * Updated versions of `crystal', `hopalong', and `flow'
944 * Imported `demon' and `loop' modes from xlockmore.
945 Changes since 3.05: * Oops, the "default-n" visual descriptor was broken;
946 it was always installing a colormap if the
947 `installColormap' preference was set, meaning that
948 `xearth', `xv' and friends were using the wrong
949 colors on 8-bit systems.
950 * Turned off HAVE_PING in `sonar', since it compiles
951 on some Linux systems, but not others of similar
953 Changes since 3.04: * Fixed an off-by-1 in `distort'.
954 * Added `sonar' hack.
955 * New version of `glplanet' (with stars.)
956 * Made all hacks exit when you type `q' or `ESC' at them,
957 and made them obey the WM_DELETE_WINDOW ClientMessage.
958 * Fixed a nonfatal buffer overrun in lament (note:
959 lament still doesn't work with MesaGL 3.0: it dies in
960 lambda_textured_triangle1(), which is Mesa's bug, not
962 Changes since 3.03: * Added an `xscreensaver.spec' file, to make it easier
963 for other folks to generate RPMs.
964 * Made the password code work on HPUX in the situation
965 where: ``enhanced security'' is available; but not
966 used; but the user typed a password more than 8
967 characters long anyway. FTSOHPUX.
968 Changes since 3.02: * Made locking work when passwd aging is enabled.
969 * Added support for PAM (Pluggable Authentication
970 Modules.) It is still turned off by default, though,
971 since it doesn't seem to work on Solaris 2.6, and has
972 been behaving erratically on Red Hat 5.1.
973 * Made each possible authentication method be tried in
974 turn until one succeeds; this means that Kerberos is
975 being used, we will first check Kerberos, and if that
976 fails, will then consult the local password file.
978 * Save and restore the bits under the passwd dialog,
979 to avoid leaving a black rectangle behind when
980 unlocking is cancelled.
981 Changes since 3.01: * Not everyone has sys/select.h, sigh...
982 Changes since 3.00: * Some fixes to `reflect'.
984 * Made it log unsuccessful attempts to unlock the screen
986 * Fixed a bug where `xscreensaver-demo' could be seeing
987 a different programs list than `xscreensaver' did.
988 Changes since 2.34: * The xscreensaver daemon no longer links against Motif
989 or Athena: demo-mode and the preferences panel are no
990 longer built in to the daemon, but are now handled by
991 an external program, `xscreensaver-demo'.
992 (I decided that this, along with the recent addition
993 of the `.xscreensaver' config file, justified bumping
994 the version number to 3.00, since this is a fairly
995 major architectural change.)
996 * Lines in the `*programs' resource may now begin with
997 the character "-", meaning "don't run this hack."
998 In this way, it's possible to disable a hack without
999 throwing away the information about it (making it
1000 easier to change your mind later.) Eventually the
1001 preferences/demo mode GUI should represent this as a
1002 checkbox or something.
1003 * Fixed a short race condition where it was possible for
1004 xscreensaver to die with a BadWindow error if it was
1005 blanking the screen just as another window was being
1007 * Made it possible to disable specific modes in `bsod'.
1008 Changes since 2.33: * Fixed a bug that was making `pipes' generate way too
1009 many valves. Made the viewpoint in `pipes' be selected
1010 randomly instead of always being -10 degrees.
1011 * Fixed a bug in the XSHM code, in the case where the
1012 server supports the XSHM extension but is not the same
1013 machine as the client.
1014 * Made `rd-bomb' default to taking up the whole screen.
1015 * Made it not try to do fading/unfading if no PseudoColor
1017 * Initial attempt at supporting VT-locking (doesn't work
1019 * Eliminated the `captureStdout' resource; now
1020 `captureStderr' controls both streams.
1021 * Added `-capture-stderr' and `-no-capture-stderr'
1022 command-line arguments.
1023 * Added `glplanet' hack.
1024 * When a hack is selected with `xscreensaver-command
1025 -select', that hack will be used until further notice
1026 (until the saver turns off, or another activation
1028 Changes since 2.32: * Made `xscreensaver-command' print error messages:
1029 the xscreensaver daemon now responds to ClientMessage
1030 events by writing a response message on a window
1031 property, instead of just writing to its stderr.
1032 * Made the ~/.xscreensaver file be automatically reloaded
1033 when the file date changes.
1034 * The password dialog and splash screen no longer depend
1035 on Motif or Athena. This should clear up a number of
1036 focus problems, and is the first step on the path
1037 toward moving all of the Motif/Athena/whatever code
1038 out of the xscreensaver daemon, and into external
1040 * Don't complain about LessTif 0.86 any more, since the
1041 new password dialog makes that problem go away.
1042 * Configure tweaks for Irix 6.5, SunOS 5.something.
1043 * New `-reflect' option to `distort'.
1044 Changes since 2.31: * Added reading and writing of a ~/.xscreensaver file,
1045 so that the Preferences panel can save its settings.
1046 * New version of `rubik'.
1047 * Added `-select N' argument to `xscreensaver-command'.
1048 * Oops, left out some of the `bubbles3d' files...
1049 Changes since 2.30: * The cursor was invisible in the password dialog. Fixed.
1050 * Made configure warn against MesaGL 2.6.
1051 * Fixed X error at startup when using non-default visual.
1052 * New version of `crystal', `ant', and `atlantis' from
1054 * New hack, `bubble3d'.
1055 * Added some new modes to `bsod'.
1056 Changes since 2.29: * Changed the order in which -lSM and -lICE are linked
1057 to be after Motif instead of before (Lesstif on Irix
1059 Changes since 2.28: * Work around a bash bug in configure.
1060 * Tweaked HPUX paths again. FTSOHPUX.
1061 * Made configure recommend against LessTif 0.86, due
1062 to a bug in that version that causes a security hole
1063 in the screen locking code. LessTif 0.87 will fix it.
1064 * Made all of the `--with' options to `configure' accept
1065 a directory option as well (so that --with-motif=/FOO
1066 will add -I/FOO/include -L/FOO/lib). I believe this is
1067 the Configure Party Line of how do to such things.
1068 * Fixed a bug where the mouse was left un-grabbed
1069 after the first time the graphics hack was changed
1070 (simplified all of the mouse-grabbing logic.)
1071 * Maybe possibly perhaps made `vidwhacker' really not
1072 leave stray xv windows around. This time for sure.
1073 * Added a new erase mode (random dots fizzling out.)
1074 * Added `-prefs' argument to `xscreensaver-command',
1075 that brings up the Preferences dialog directly (it
1076 seems that nobody ever noticed the `Preferences' button
1077 on the Demo Mode dialog, maybe this will help.)
1078 * Added a splash screen. Turn it off with *splash:false.
1079 Changes since 2.27: * Better macsbug text in `bsod'.
1080 * New version of `distort' with many new modes.
1081 * Plugged a leak in `coral'.
1082 * Tweaked configure for HPUX.
1083 * Removed some compiler warnings.
1084 * More consistent usage of stderr versus stdout.
1085 * More diagnostics should an X error occur.
1086 * Fixed a possible crash in SGI-specific unfading code.
1087 Changes since 2.26: * Improved version of `distort'.
1088 * Made `lament' compile against OpenGL 1.0 (though it
1089 still requires 1.1 to work properly.)
1090 * Updated my email address and home page.
1091 Changes since 2.24: * Improved motion in `rd-bomb'.
1092 * Added XSHM (shared memory extension) support to the
1093 `distort', `interference', `moire', `rd-bomb', and
1094 `swirl' hacks, which speeds them up a bit.
1095 * Added `lament' hack.
1096 Changes since 2.23: * Tweaked the order of the -L options again.
1097 * Cleaned up configure's `--help' message.
1098 * Added `kumppa' hack.
1099 * Smarter maze-solving algorithm in `maze'.
1100 * Took `xlyap' out of the default list of hacks, since
1101 it's just incredibly buggy (and slow.) Maybe someday
1102 someone will fix it...
1103 * Added `distort' hack, but didn't add it to the default
1104 list (yet) because it's still too slow.
1105 * Made the Athena demo dialog look more like the Motif
1106 version; it has a text-entry field now, too.
1107 * Made the Athena password dialog echo asterisks, like
1108 Motif does, instead of using a flyspeck font.
1109 * Some random configure tweaks.
1110 * Added a `timestamp' resource that makes the `-verbose'
1111 messages include the time at which they were printed.
1112 Changes since 2.22: * The fix for SGI's ``scheme'' nonsense broke things, and
1113 let the user's "*background" resource show through.
1114 Fixed it in a different way.
1115 Changes since 2.21: * Added support for the DPMS server extension (Display
1116 Power Management System.)
1117 * Made configure advertize the `--enable-subdir' option a
1118 little more, since that seemed to cause some people
1119 stress. Also, made that directory be built into the
1120 xscreensaver executable, as a hardcoded prefix to
1121 $PATH. (Might help, shouldn't hurt.)
1122 * Made configure prefer the two-arg gettimeofday to the
1123 one-arg version, since AIX doesn't have any prototypes.
1124 * Made it work with Xaw3d (the 3D Athena library.)
1125 * Made `make install' create directories as necessary.
1126 * New version of lmorph from Sverre.
1127 * Added `crystal' and `discreet' hacks from xlockmore.
1128 * Added a new mode to `bsod'.
1129 Changes since 2.20: * Made `xscreensaver-command -time' use different words.
1130 (It now describes the two states as "screen blanked
1131 since..." and "screen non-blanked since..." instead of
1132 "active since..." and "inactive since..." which a lot
1133 of people interpreted as meaning the opposite of what
1135 * Improved some error messages, in the hopes of making
1136 the distinction between the xscreensaver and
1137 xscreensaver-command programs more obvious.
1138 * Rewrote (and reorganized) parts of the xscreensaver and
1139 xscreensaver-command manual pages.
1140 * Renamed xscreensaver's `-lock' command-line option to
1141 be `-lock-mode', to avoid confusion with the `-lock'
1142 option to xscreensaver-command, which does a totally
1144 * Removed xscreensaver's `-demo' command-line option for
1145 a similar reason; use `xscreensaver-command -demo'
1147 * Disabled SGI's ``scheme'' nonsense in a better way than
1148 fully-qualifying the background colors in every single
1150 * Fixed some other minor cosmetic problems when *sgiMode
1152 * Fixed an X error in `bsod -root' (how ironic...)
1153 Changes since 2.19: * Fixed a bug that caused the mouse to sometimes not be
1154 grabbed properly (meaning the window manager menu could
1155 pop up over the demo-mode display.)
1156 * Fixed a bug that made the stderr output sometimes get
1158 * Fixed a bug that made the demo-mode scrollbar move too
1160 * Protected against a possible buffer overflow.
1161 * Made `vidwhacker' not leave stray xv windows around.
1162 * New version of `ant' so that Bagley doesn't calve.
1163 * Make configure on AIX get XShm from the right library.
1164 Changes since 2.18: * One file was missing from the tar file. Fixed.
1165 Changes since 2.17: * Oops, atlantis wasn't being built by default. Fixed.
1166 * Added `epicycle' hack.
1167 * Added `interference' hack.
1168 * Added `truchet' hack.
1169 * Added `bsod' hack.
1170 * Added some new modes to `vidwhacker'.
1171 Changes since 2.16: * Added a -window-id argument to most hacks, so that they
1172 can draw on arbitrary externally-provided windows.
1173 * Synched with xlockmore 4.11a01.
1174 * Added `flow' hack.
1175 * Added `atlantis' GL hack.
1176 * Renamed `puzzle' hack to `jigsaw', since xlock already
1177 had a different mode called `puzzle'.
1178 * Made it self-configure properly when Motif 2.1.0 is
1179 being used (requires -lXp now, sigh...)
1180 Changes since 2.15: * Made `flag' able to do XPM images.
1181 * New look for the xscreensaver logo (`xroger').
1182 * Fixed compilation error on Suns with adjunct passwords.
1183 * Got multi-architecture builds working again.
1184 * Some configure tweaks for building on HPUX and Solaris.
1185 * Fixed bug in decayscreen.

1191 * Made unfading a bit smoother.
1192 * Added `vidwhacker' hack (not installed by default.)
1193 * Added `stairs' hack.
1194 * Split `escher' into `cage' and `moebius', as per
1196 * Changed subprocess handling to use sigaction() instead
1197 of signal() if it's available (this is necessary for
1198 SCO but should work fine on other systems too.)
1199 * Various other tweaks.
1200 Changes since 2.13: * Better fix for the Motif drag-and-die lossage.
1201 * Put in some kludges to work around a LessTif bug.
1202 * XScreenSaver is known to work with LessTif 0.82 now.
1203 * Made fading work on high-end SGI video hardware.
1204 * Fixed another SGI-specific bug in screen grabbing;
1205 will the madness never cease?
1206 * Fixed another crash in `xlyap'.
1207 Changes since 2.12: * Made `decayscreen' do directions other than down.
1208 * Improved `puzzle'.
1209 * Fixed a crash in `xlyap'.
1210 * Added CDE info to the man page, removed `cde.txt'.
1211 * Configure tweaks for Zippy.
1212 * Turned off the signal handling in `bubbles' because
1213 it was sometimes failing to die.
1214 * Added `hacks/xscreensaver-sgigl.c' to make it possible
1215 to run SGI's ElectroPaint hack (/usr/demos/bin/ep)
1216 with xscreensaver. Finally!
1217 * Fixed a buffer overrun in the locking code that some
1218 wily, malicious cracker must have slipped in.
1219 * Disabled Motif drag-and-drool in the dialog box
1220 buttons, since it's broken in some old versions of
1222 Changes since 2.11: * Added `README.debugging'.
1223 * Added `puzzle' hack.
1224 * Added `xlyap' hack.
1225 * Added `default-n' as a visual name, so that one can
1226 have -install on by default, but turn it off for
1227 certain poorly-behaved hacks (like xv.)
1228 * Added support for grabbing frames of external video
1229 (on SGI) to the screen-grabbing hacks (decayscreen,
1230 slidescreen, slip, blitspin, and puzzle.)
1231 * Improved look of tiles in `slidescreen'; fixed its
1232 color allocation problem.
1233 Changes since 2.10: * Tweaked `blitspin', added it to the default list.
1234 * Added `lissie', `mountain', `triangle', `worm',
1235 `rotor', and `ant' from xlockmore.
1236 * Updated `sierpinski', `galaxy', and `lisa'.
1237 * Thickened the lines in `braid' and `lmorph'.
1238 * Updated VMS makefiles.
1239 * Renamed `fract' to `vines'.
1240 * Added `xjack' hack.
1241 * Made a few more hacks use erase.c, and added a few
1243 * Fixed compilation problem with Sun's version of OpenGL.
1244 * Added ability to use sigaction() instead of signal()
1245 to work around a SCO kernel bug.

1247 * Configure tweaks for *BSD.
1248 Changes since 2.07: * New hacks `rd-bomb' and `coral'.

1261 configure to detect the extra-random -Xss library.
1262 Changes since 2.03: * HP configure tweaks. Detect and warn about LessTif.
1263 * Fixed low-color behavior of `goop', `pyro', `starfish',
1264 `greynetic', `flame', `halo', and `moire'.
1265 Changes since 2.02: * Fixed flicker in `pipes'. Fixed 3d in `bouboule'.
1266 * Added `munch' hack.
1267 * Added basic dependencies to the Makefile.in files.
1268 Changes since 2.01: * Fixes for compiling with the MIT saver extension.
1269 * Made the yow/fortune program be a configure option.
1270 * Various configure tweaks.
1271 Changes since 2.00: * Added `goop' and `starfish' hacks.

1273 * Made `attraction' use the new colormap allocator.
1274 * Added better $PATH diagnostics.
1275 * There was a bug in frand! Color selection should be
1277 Changes since 1.34: * Converted to use `configure' instead of `imake'.

1280 * Made the stderr text use overlay planes, if possible.
1281 * Reworked the xlockmore compatibility stuff again.
1282 * Added `gears', `superquadrics', `escher', `pipes',
1283 and `sproingies' hacks (depend on OpenGL.)
1284 Changes since 1.33: * Fixed some bugs, made fading be a little smoother.
1285 Changes since 1.32: * Made it work with multi-headed displays.
1286 * Generalized sub-process management (Unix sucks!)
1287 * Added interactive mouse frobbing to Julia.
1288 * Added (untested) support for HPUX shadow passwords.
1289 * Made normal non-shadow passwords be checked if the
1290 shadow passwords aren't accessible for some reason.
1291 Changes since 1.31: * Removed *colorPrograms and *monoPrograms resources:
1292 made it possible to specify the desired visual on a
1294 * Cleaned up / restructured the driver: no more globals.
1295 * Made the Motif and Athena dialogs share more code.
1296 * Probably fixed some Athena colormap-installation bugs.
1297 * Fixed screen grabbing (cmap) on SGI 12-bit PseudoColor.
1298 * Fixed divide-by-zero in bright random colormaps.
1299 * Added an improved version of xlock's `flag' hack.
1300 * Made unfading work better, and not flicker on SGIs.

1306 * Ported `swirl' and `bouboule' hacks from xlockmore.
1307 * Made the driver more careful about not leaving bits on
1308 the screen, or allowing other windows to raise
1309 themselves: it now re-blanks the screen every so often.
1310 * Added `-time' option to `xscreensaver-command'.
1311 * Improved SGI screen-grabbing some more: now it can grab
1312 TrueColor screens into PseudoColor windows and have the
1313 colors still come out semi-reasonably.
1314 Changes since 1.29: * Made `slidescreen' and `decayscreen' work better on
1315 SGIs when windows of different visuals are present, by
1316 using the XReadDisplay() extension to get a true 24-bit
1317 image out of the frame buffer.
1318 * Made `noseguy' be in color, if compiled with XPM.
1319 * Ported `braid', `drift', `fract', `galaxy', `grav',
1320 `ifs', `julia', `laser', `lightning', `penrose',
1321 `sierpinski', `slip', `spiral', and `strange' hacks
1323 * Merged `hopalong' hack with a more recent version.
1325 Changes since 1.27: * Added `deco', `moire', and `kaleidescope' hacks.
1326 * Merged in support for non-Motif locking and demo mode.
1327 * Made `blitspin' and `bubbles' work in TrueColor.
1328 * Fixed a stupid bug I introduced in `imsmap'.
1329 * Added `poly' and `gravity' options to `qix'.
1330 Changes since 1.26: * Added support for SGI SCREEN_SAVER extension.
1331 * Made `fade' and `unfade' work on 8-bit SGIs.
1332 * Made the dialog boxes more Motify.

1335 * Added viscosity and mouse-control to attraction.
1336 * Fixed possible bad color choices in qix and attraction.
1337 * Added ramp-mode to halo.
1338 * Added a new RNG, which is faster and more portable
1339 than using the RNG in libc.
1340 * Made locking work on SCO.
1341 * Various other minor tweaks that I don't remember.
1342 Changes since 1.24: * Made it capture the stdout/stderr of its subprocesses
1343 and present them on the screensaver window itself.
1344 * Made demo mode work correctly with non-default visuals
1345 and color maps, instead of always using the defaults.
1346 * Added -visual argument to all included screenhacks.
1347 * Support for the R6 MIT-SCREEN-SAVER server extension.
1348 * Made the demo mode list scroll properly.
1349 * Added `pedal' hack.
1350 Changes since 1.23: * Fixed some private-colormap oddities in slidescreen,
1351 decayscreen, and xroger. Fixed apparent conservation-
1352 of-mass problem in pyro; made the shrapnel round.
1353 Changes since 1.22: * Minor tweaks for IRIX5; fixed locking race condition.
1354 Changes since 1.21: * Minor tweaks for X11R6.
1355 * Fixes for non-default visuals.
1356 Changes since 1.20: * Fixed bug in color blitspin; added default image.
1357 * Added diagnostics to noseguy. Fixed off-by-one
1358 error in flame. Added some missing casts.

1370 * Moved the hacks into their own directory.
1371 * Made all `time' parameters accept the 00:00:00 syntax,
1372 so that even the parameters which are normally read as
1373 minutes can be specified in seconds.
1374 * Added colormap cycling to `imsmap'.
1375 * Made hyper work with K&R compilers.
1376 Changes since 1.13: * Added `orbit' option to `attraction' hack.

1384 * Can use `xv' as a slideshow without using up colormap
1385 entries while the screen is not blanked.
1386 * Fixed a BadDrawable error in non-XIdle mode.
1387 * Added `blitspin' and `imsmap'.
1388 Changes since 1.0: * Current list of included hacks is now: qix, helix,
1389 rorschach, attraction, greynetic, rocks, pyro,
1390 hopalong, and noseguy.
