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

110 screens, and for systems where RANDR lies and says the
112 * When the password dialog has timed out or been
113 cancelled, don't pop it right back up a second time.
114 * Password timeouts/cancels don't count as
116 * Retired some of the older, less interesting savers:
117 say goodbye to `bubbles', `critical', `flag', `forest',
118 `glforestfire', `lmorph', `laser', `lightning', `lisa',
119 `lissie', `rotor', `sphere', `spiral', `t3d', `vines',
120 `whirlygig', and `worm'.

134 entering numbers that are out of range.
135 * Added "Reset to Defaults" button on X11.
136 * Added relevant Wikipedia links to many of the screen

139 * The `-fps' option now shows CPU load.
140 Changes since 5.05: * Xinerama/RANDR fixes: this time for sure. It should
141 now work to add/remove monitors or resize screens at
143 * New hack, `skytentacles'.
144 * New version of `gleidescope'.
145 * Added the `-log' option to the xscreensaver daemon,
146 since a truly shocking number of Linux users seem to
147 have no idea how to redirect output to a file.
148 * Added `-duration' arg to most image-loading hacks,
149 so that they pick a new image every few minutes.
150 * Added an ATM crash to BSOD.
151 Changes since 5.04: * New hacks, `cubicgrid', `hypnowheel', and
152 `lcdscrub' (which isn't really a screen saver).

154 * Fixed double-buffering problems in `cubestorm' and
156 * Better handling of horizontal scroll wheels.
157 * Attempt to work around latest Xinerama braindamage:
158 if the server reports overlapping screens, use the

163 text-displaying hacks to fail on some systems.
164 * Hopefully fixed font-related System Preferences crashes
166 * The recent PAM changes broke the "Caps Lock" warning
167 in the password dialog, the failed login warnings, and

170 fallout from the recent PAM changes...)
171 * New hacks, `moebiusgears', `abstractile', and
173 * Rewrote `gears' to use better (involute) gear models,
174 and to be more random.
175 * Minor updates to `cwaves', `voronoi', `deco',
176 `glcells', `rd-bomb', `fireworkx' and `webcollage'.
177 * `pong' can now display the current time as the score.

192 `flipflop', `flipscreen3d', `fliptext', and `carousel'.
193 * Enabled multi-threaded OpenGL on MacOS.
194 Changes since 5.00: * Backed out recent locale-related changes, since they
195 broke far more things than they fixed.

197 * `xflame' and `flag' ignore bitmap option on MacOS.
198 * `speedmine' prefs work on MacOS.
199 * Better explosions in `boxed'.

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

390 `blocktube', and `glmatrix'.
391 * Updates to `cloudlife', `engine', `xmatrix', and
393 * Rewrote `glslideshow': it should work on somewhat
394 wimpier video cards now.
395 * Various portability tweaks.
396 Changes since 4.09: * New hacks, `cloudlife' and `klein'.
397 * Added Apple ][+, HPUX, and OS/390 sessions to BSOD.
398 * Added some Matrix Reloaded text to `xmatrix'.
399 * Updates to `webcollage', `eruption', `jigglypuff',
400 `metaballs', and `endgame'.
401 * Completely ignore the `memoryLimit' setting now,
402 since it was still causing people GL grief.
403 * Various minor fixes.
404 Changes since 4.08: * New hacks, `flyingtoasters', `bouncingcow',
405 `jigglypuff', and `glslideshow'.
406 * More models in `engine'.
407 * Rewrote `xscreensaver-getimage' to remove reliance on
408 external image loaders (xv, chbg, xloadimage, etc.)
409 and to reduce flicker when loading files.
410 * Made `gflux' and `flipscreen3d' be mouse-spinnable.
411 Changes since 4.07: * New hacks, `atunnels' and `piecewise'.
412 * Physics improvement in `fluidballs'.
413 * Various fixes for XDarwin systems (X11 on MacOS X.)
414 * Added -clock option to `barcode'.
415 * Minor fixes to `endgame', `flurry', `flipscreen3d',
417 Changes since 4.06: * New hacks, `flurry', `metaballs', `eruption',
418 `popsquares', and `barcode'.
419 * Minor updates to `maze' for high density mazes.
420 * Added double buffering to `fluidballs' and `whirlygig'.
421 * Bug fixes for running xscreensaver to a remote XFree86
422 display (which nobody would ever do...)
423 * Updated `webcollage' (faster Alta Vista searching.)
424 * Updated `glplanet' so the sun sets in the west.
425 * Updated `sproingies' with smooth, unsegmented surfaces.
426 * Fixed Perl version-sensitivity in
427 `xscreensaver-getimage-file'.
428 * Fixed GTK2 scrolling bug in `xscreensaver-demo'.
429 Changes since 4.05: * New hack, `glblur' (disabled by default, since it
430 requires fast OpenGL texture support.)
431 * New hack, `halftone'.
432 * Updates to `endgame', `queens', `bumps', `glplanet',
433 `engine', and `circuit'.
434 * New version of `menger' that uses far fewer polygons.
435 * Fixed minor bug in `critical' that could cause some
436 bogus X servers to crash.
437 * Better labels in `molecule': the labels now appear to
438 be attached to the atoms, instead of floating in front
440 * Fixed bug that could rarely cause GL hacks to fail to
441 double-buffer (causing intermittent flickering.)
442 * Fixed a relative-URL-parsing bug in `webcollage'.
443 * Fixed a bug that (sometimes) caused the window manager
444 close box to kill `xscreensaver-demo' with a crash
445 instead of a graceful exit.
446 * Updated xscreensaver.pam to the Red Hat 7.3 way.
447 * More Gnome2-related configure crap.
448 * Updated to latest `config.guess' and `config.sub'.
449 * Fixed occasional core dump in `distort'.
450 * Added a Linux fsck failure and kernel panic to `bsod'.
451 * Added MacOS X kernel panic to `bsod'.
452 * Fixed a bug in `bsod' (all bsod bugs are ironic.)
453 * Fixed a bug that caused `xscreensaver-gl-helper' to
454 print a nonsense visual ID with some versions of
455 `printf': this could cause GL programs to display
456 incorrectly (e.g., flickery.)
457 Changes since 4.04: * More `configure' tweaks to try and get things working
458 on systems that both Gtk 1.x and 2.x installed.
459 * New hack, `endgame'.
460 * Minor updates to `gltext'.
461 Changes since 4.03: * Support for GTK 2.x / GNOME 2.x.
462 * The `configure' script will now use `pkg-config' if
463 you have it, in preference to `gtk-config', etc.
464 * New hacks, `lavalite', `queens', and `anemone'.
465 * Minor updates to `spheremonics', `gltext', `xmatrix'.
466 * You can use the mouse to manually spin most of the GL
467 hacks now (when they are displaying in a window.)
468 * Fixed a bug in `webcollage' (due to recent Alta Vista
469 url changes) that was causing it to try and load
470 incorrect image URLs.
471 * Made `xscreensaver-getimage' use gdk_pixbuf if it is
472 available: this means that those hacks that load images
473 will no longer rely on "xv", "xloadimage", etc. This
474 will close a race condition that could sometimes cause
475 your desktop background to be changed; and also makes
476 it possible for those programs to operate on image
477 files when running in windowed mode.
478 * `webcollage' can now be used in conjunction with
479 `driftnet' to display images snooped from your local
480 ethernet instead of obtained from search engines.
481 * Added man pages for all the hacks that didn't have
483 Changes since 4.02: * New hack, `spheremonics'.
484 * Minor updates to `webcollage', `cage', `moebius',
485 `morph3d', `boxed', `circuit', and `helix'.
486 * `pulsar' and `extrusion' can now load texture JPEGs.
487 * `rubik' now does non-square cubes.
488 * `fluidballs' now does various sizes of balls.
489 * `menger' and `sierpinski3d' now also show polygon
491 * `molecule' displays real subscripts in the formulae.
492 * GTK internationalization/localization support.
493 * Better detection of the various versions of libxml.
494 * Upgraded to autoconf 2.53 (from 2.13.)
495 Changes since 4.01: * Plugged a few minor leaks in `xscreensaver' and
497 * New hacks, `cubenetic' and `fluidballs'.
499 * Fixed sphere projection error in `glplanet'; installed
500 a better image of earth.
501 * Added Win2K and MacOS 1 crashes to `bsod'.
502 * Put back previous (better) version of `forest' that
503 was accidentially downgraded in the last release.
504 * New version of `bumps'.
505 * Made FPS computation in GL hacks more efficient: it
506 will influence the results less, thus resulting in
507 higher (but more accurate) reported frame rates.
508 Changes since 4.00: * New hacks: `twang', `glsnake', `boxed', `sballs',
510 * New hacks `apollonian', `euler2d', `juggle',
511 `polyominoes' and `thornbird', from xlockmore.
512 * Merged recent xlockmore changes into `ant', `braid',
513 `demon', `discrete', `drift', `fadeplot', `forest',
514 `grav', `hopalong', `ifs', `laser', `lightning',
515 `lisa', `lissie', `loop', `mountain', `penrose',
516 `rotor', `sierpinski', `slip', `sphere', `spiral',
517 `strange', and `vines'.
518 * Fixed the `gltext' bug that sometimes caused
519 horizontal lines to vanish again. This time for sure.
520 * Sped up `webcollage' by adding a C helper program to
521 replace the PPM pipeline. It also pastes images
522 semi-transparently now.
523 * Added support for the gdk_pixbuf library: if this lib
524 is available, then `blitspin', `xflame', and `flag'
525 can load GIF, JPEG, and PNG images in addition to XPM
527 * Fixed a rare race condition where the desktop-grabbing
528 hacks could sometimes leave the screen wedged, if the
529 user moved the mouse exactly when they were grabbing
530 the screen image (it would un-wedge the next time the
531 saver timed out or was activated.)
532 * Fixed incorrect colors in the screen-grabbing GL hacks
533 (`gflux' and `flipscreen3d'.)
534 * Made SIGHUP restart the daemon process (though using
535 `xscreensaver-command -restart' is still the preferred
537 * Tweaks to `xspirograph'.
538 * Minor configure and portability tweaks.
539 Changes since 3.34: * Redesigned `xscreensaver-demo' GUI: it now includes
540 small-preview and per-hack configuration dialogs.
541 * Added three new modes of operation: `One Screen Saver',
542 `Blank Screen', and `Don't Blank' (in addition to the
543 historical `Random Screen Saver').
544 * Configure now defaults to installing the hacks in
545 <prefix>/lib/xscreensaver/ instead of <prefix>/bin/.
546 (Most distros already did it this way.)
547 * New GL hacks, `menger', `engine', `flipscreen3d'.
548 * Made `sierpinski3d' be more colorful.
549 * New versions of `xmatrix' and `nerverot'.
550 * Fixed a bug in `starwars' that made the font be drawn
551 with thin lines in -root mode.
552 * Fixed a bad colormap bug in `crystal' that could make
553 *subsequent* hacks malfunction!
554 * Made `gflux' able to grab screen images (`-mode grab').
555 * Updated `webcollage' for recent search engine changes.
556 * Removed most command-line options to `xscreensaver':
557 just edit the ~/.xscreensaver file instead.
558 * Improved behavior on multi-screen and Xinerama systems:
559 the mouse now stays on the screen where the user left
560 it, and the password and splash dialogs always appear
561 on the screen that has the mouse.
562 * Made the splash dialog use more Gtk-like colors;
563 made it have only two buttons, "Settings" and "Help".
564 * Made `sonar' understand `.ssh/known_hosts2' format
565 files, and be better about stripping out illegal
567 Changes since 3.33: * Turned `memoryLimit' off by default, sigh. Apparently
568 some versions of the GL libraries (appear to) allocate
569 hundreds of megs for every GL program, so `memoryLimit'
570 was causing GL programs to malfunction or crash on
572 * Improved fading on TrueColor XFree86 4.1.x systems.
573 * New GL hack, `circuit'.
574 * Added `fuzz' mode to `decayscreen'.
575 * New version of `whirlygig'.
576 * Added links to `xplanet' and `sphereEversion'.
577 * Fixed rare race condition that could make `sonar' hang.
578 * Fixed potential crash in `speedmine'.
579 * Made `xscreensaver-demo' not crash when imageDirectory
580 was set to a non-existent directory.
581 * Made `xscreensaver-getimage-video' invoke XawTV's
582 `streamer' program better.
583 * Made `phosphor' and `starwars' deal with CR, LF,
584 or CRLF line endings.
585 * Changes for Cygwin compilation environments.
586 * Made `sonar' compile on systems that can't ping.
587 * Configure changes for HPUX 10.20.
588 * Made PAM code work on Red Had 4.2 systems.
589 * Made `xscreensaver-command -deactivate' work when the
590 saver is not active: what that does is reset the idle
591 timer, as if keyboard input had been detected. This
592 was added for the benefit of people writing DVD-playing
593 software: they can now prevent the screensaver from
594 kicking in by sending a -deactivate message once a
595 minute while the movie is playing and not paused.
596 * Various minor portability tweaks.
597 Changes since 3.32: * New hacks, `speedmine' and `whirlygig'.
598 * Sped up `pyro', made the explosions look a bit better.
599 * Added better stars to `glplanet' and `starwars'.
600 * Many internal changes to `webcollage'.
601 * Some new options to `attraction'.
602 * Minor fix to `noseguy' to avoid un-erased pixels.
603 * Rewrote the screen-eraser effects so that they complete
604 in the same amount of time regardless of how slow
605 your X server is (some of them were glacial on servers
607 * Fixed a potential free memory reference that could
608 sometimes cause a crash at startup.
609 * Possibly fixed a problem that could cause the daemon
610 to crash with an X error. I was never able to
611 reproduce this problem, but I think I might have
612 figured out what caused it.
613 * Worked around a problem that caused PAM authentication
614 to fail on some Red Hat 7.x systems.
615 * Added a `memoryLimit' parameter that controls the
616 amount of memory a graphics hack may allocate: if they
617 try to allocate more than this, malloc() will fail
618 (and they will exit or (safely) crash, rather than
619 hogging memory.) Default is 50M.
620 * Made `gnome-help-browser' be the default way to display
621 man pages in `xscreensaver-demo', if running on a
623 Changes since 3.31: * The image-manipulating hacks (`slidescreen', etc.) can
624 now operate on randomly chosen image files from disk,
625 or on frames captured from the system's video input,
626 instead of (or in addition to) manipulating images of
628 * Rewrote `vidwhacker' to use the new image-grabbing
630 * Made fading work on TrueColor XFree86 4.x systems.
631 * Fixed a subtle rendering bug in `atlantis' (the fish
633 * Made `atlantis' have a texture simulating light
634 reflections from the surface of the ocean.
635 * Fixed up label placement in `molecule'.
636 * Better color bars in `xteevee'.
637 * Made `install-strip' not try to strip scripts.
638 Changes since 3.30: * Put in more sensible defaults for DPMS, and updated
639 the documentation to reflect the fact that all your
640 DPMS settings are now belong to xscreensaver.
641 * Fixed the `xscreensaver.spec' file so that `--force'
643 * New versions of `rotzoomer' and `nerverot'.
644 * Fixed an OSF/1 compilation problem in `molecule'.
645 Changes since 3.29: * New hacks, `molecule', `dangerball', and `rotzoomer'.
646 * New version of `gflux'.
647 * Made `gltext' able to display the current time.
648 * Fixed a floating-point-precision problem in `gltext'
649 that sometimes caused horizontal lines to vanish.
650 * Removed the `-window-id' option from the hacks:
651 it never worked right, and was unnecessary.
652 * Made the `starwars' hack use thicker lines, antialias
653 the text, and fade out at the far edge instead of just
655 * Fixed an SHM segment leak in `moire'.
656 Changes since 3.28: * Better rendering of the new logo.
657 * New hack, `gltext'.
658 * Added `-planetary' option to `gears', to draw a
659 different kind of gear system.
660 * Made motion and rotation be smoother in `gears',
661 `glplanet', `moebius', `rubik', and `sierpinski3d'.
662 * Improved coloration in `sierpinski3d'.
663 * Made the GL hacks react to window size changes.
664 * Made most of the GL hacks take a -fps option (like
665 `pulsar' did), so you can use them to benchmark your
667 * Fixed the previous fix to `sonar'.
668 * Minor fix to `nerverot'.
669 Made sonar able to ping hosts on DEC OSF1.
670 * Eliminated a bogus "didn't get enough colors" warning
671 in some of the hacks.
672 Changes since 3.27: * New logo for xscreensaver!
673 * New hacks, `starwars' and `stonerview'.
674 * Made the motion of the bouncing ball in `stairs' be a
676 * Made newly-added screenhacks be added to .xscreensaver
677 automatically: if there are hacks in the app-defaults
678 file that are not also in ~/.xscreensaver, they will
679 be added to the end of the list.
680 * Redid the `Screensaver Options' part of the control
681 panel; xscreensaver now lets you configure your DPMS
683 * Fixed some Makefile problems with non-GL builds.
684 * Fixed detection of MesaGL for version 3.3.
685 * Better workaround to Red Hat 7.0's broken gcc.
686 * Added Sparc Solaris kernel panic to `bsod'.
687 Changes since 3.26: * New hacks: `zoom' and `whirlwindwarp'.
688 * Fixed a free-memory-reference bug in `sonar'.
689 * Better error handling when there are no suitable GL
691 * Added diagnostic dialog when xscreensaver-demo is
692 unable to launch xscreensaver (e.g., when running as
694 * Fixed a bug that caused screenhack argument changes
695 to be ignored when xscreensaver-demo was running as
696 root (if "root" and "nobody" have different home
698 * Made the programs default to ":0" if $DISPLAY is unset.
699 * Made the `-verbose' output include information about
700 which server extensions were supported at compile time.
701 * Worked around Red Hat 7.0's broken gcc 2.96.
702 * Updated default delays on the GL hacks to look better
703 on machines with super-fast 3D hardware.
704 * Install `screensaver-properties-capplet' to work around
705 the usual egregious GNOME lossage.
706 Changes since 3.25: * Added "enabled" checkboxes in the list of hacks in
707 xscreensaver-demo (Gtk version only.)
708 * New hacks `hyperball', `xrayswarm', and `gflux'.
709 * New versions of `nerverot', `galaxy', and `hypercube'.
710 * Small fixes to `phosphor', `shadebobs', `xflame',
712 * Added external helper program `xscreensaver-gl-helper'
713 to figure out which X visual to use for OpenGL
715 * Configure updates for XFree86 4.0, and for BSD.
716 * Made it be more tolerant of bogus /etc/group files.
717 * When installing the PAM config file, first try to just
718 copy an existing "xdm" or "login" config file, so that
719 xscreensaver does authentication in the same way as the
721 Changes since 3.24: * New hack, `nerverot'.
722 * Added BSD kernel panic to `bsod'.
723 * New version of `shadebobs'.
724 * New version of `petri'.
725 * Updated `webcollage' to handle recent Altavista URL
726 format changes; made it search the AP photo gallery.
727 * Revamped command-line options of `sonar' and made it
728 properly handle subnets.
729 * The `bubbles' hack can now trickle up or down the
731 * The `xsublim' hack can now read its text from programs.
732 * Support for GLE version 3 in `extrusion'.
733 * Fixed compilation problems in `maze'.
734 * Fixed a rare crash in `flow'.
735 * Fixes for minor installation problems.
736 Changes since 3.23: * Added `-ignorant' option to `maze' hack.
737 * Updates to `critical', `bsod', `xflame', and `flow'.
738 * Added support for Kerberos 5 (via its Kerberos 4
739 compatibility layer.)
740 * Fixed a bad leak in `xteevee'.
741 * Updated `webcollage' to handle recent Altavista URL
743 * Removed xscreensaver-demo's `Ok' and `Cancel' buttons,
744 since they were confusing people: all changes are now
746 * Made xscreensaver-demo install itself into the Gnome
748 Changes since 3.22: * Fixed some misplaced text fields in the Motif version
749 of xscreensaver-demo; fixed a crash in the Gtk version
750 that would happen if the programs list was empty.
751 * Fixed a recently-introduced bug in `pulsar'.
752 * Made `sierpinski3d' use solid tetrahedrons instead of
754 * Added `-trace' option to `xmatrix'.
755 * Added new hacks `xteevee' and `xspirograph'.
756 Changes since 3.21: * Fixed some bugs in xscreensaver-demo.
757 * Rewrote the Motif version of xscreensaver-demo to
758 match the new Gtk version.
759 * The Athena toolkit is no longer supported.
760 Changes since 3.20: * Tweaked the xscreensaver-demo UI (Gtk only.)
761 * Fixed a few visual selection bugs. I think the proper
762 GL visual should be used with nVidia systems now.
763 * Made the Makefiles obey $install_prefix.
764 * Made the `xscreensaver.spec' file able to generate both
765 GL and non-GL packages simultaneously.
766 Changes since 3.19: * Added new hacks `ripples' and `sierpinski3d'.
767 * Made `xscreensaver-command -exit' be silent when no
768 screen saver was running (instead of complaining.)
769 * Made `webcollage' and `vidwhacker' use `xloadimage'
770 when available (in addition to `xli' and `xv'.)
771 * Improved memory usage in `petri' and gave it a hard
772 cap on how much memory it can allocate.
773 * Added `-watch' option to `xscreensaver-command'.
774 * Made `xscreensaver-demo' come up with the
775 most-recently-run hack selected by default.
776 * Rewrote the Gtk version of `xscreensaver-demo'.
777 It's a lot easier to use now.
778 * Extended the format of the programs list in the
779 .xscreensaver file, for the benefit of the new
780 capabilities of `xscreensaver-demo'.
781 NOTE: you might want to delete your ~/.xscreensaver
782 file and allow it to be re-created! The old one
783 should still work, but xscreensaver-demo won't be as
785 Changes since 3.18: * Fixed gcc dependencies in `bumps' and `ccurve'.
786 * New hack, `extrusion'.
787 * Some of the web sites that `webcollage' was using as
788 its sources changed formats; tweaked it to understand
790 * Added typeahead in the password dialog: if the screen
791 is locked, and you unlock it by typing a character,
792 that key will be automatically inserted in the
793 password dialog (unless it is Return, Enter, Space,
794 or a non-printing key like Shift.)
795 * Made `xmatrix' take a `-small' option, since some
796 folks with tiny screens prefer a smaller font.
797 Changes since 3.17: * New versions of `shadebobs', `lmorph', and `distort'.
798 * Added `ccurve', `blaster', and `bumps' hacks.
799 * Replaced `forest' hack with a rewritten version.
800 * Worked around a Xinerama server bug.
801 * Fixed a bug I introduced in 3.10 that caused some
802 hacks to print out superfluous warnings about not
803 having gotten enough colors.
804 * Made `sproingies' obey the `-delay' option.
805 * Fixed a portability bug in `shadebobs'.
806 * Made `webcollage' and `vidwhacker' use `xli' in
807 preference to `xv', if it is available.
808 * Added a new source of images to `webcollage'.
809 * If running under KDE, xscreensaver will add itself to
810 KDE's list of screensavers (via xscreensaver.kss.)
811 * Improved detection of GL libraries.
812 * Made the password dialog include the date and time.
813 Changes since 3.16: * New version of `webcollage' -- deals better with
814 corrupted images, and can use an http proxy.
815 * New hack, `xsublim' (run it in the background,
816 rather than adding it to the programs list.)
817 * The xscreensaver daemon was leaking a file descriptor
818 each time you edited your .xscreensaver file. Fixed.
819 Changes since 3.15: * New version of `shadebobs'.
820 * Improved image selection in `webcollage', and sped it
822 * Made configure find the right version of perl.
823 * Rewrote the CGI part of `webcollage'.
824 * `make clean' was deleting some things it shouldn't.
825 * Fixed a typo in the default programs list.
826 Changes since 3.14: * Added `webcollage' and `shadebobs' hacks.
827 * Added a `-stdout' arg to `vidwhacker' so that it can
828 be used in a pipeline.
829 * Made `petri' use less memory.
830 Changes since 3.13: * Various improvements to the Gtk port.
831 * Turned off PAM by default on Solaris, since PAM seems
832 generally to be misconfigured out-of-the-box.
833 * Made the `--without-gtk' configure option work.
834 * Made configure check the Gtk version number, since it
836 * Fixed a bug in the code that attempted to prevent
837 changes of screen resolution while the screen is
839 * Fixed a race condition in `xscreensaver-demo' that
840 could cause an X error at startup.
841 * Added `-transparent' option to `deluxe'.
842 * Added `petri' hack.
843 Changes since 3.12: * Ported `xscreensaver-demo' to Gtk.
844 * Made it possible to build Motif, Gtk, and Athena
845 versions of `xscreensaver-demo' in the same directory
846 without reconfiguring.
847 * Made `xscreensaver-demo' chase symlinks before writing
848 the .xscreensaver file, so that if .xscreensaver is
849 itself a symlink, the underlying file will be replaced
851 * Some Makefile and configure tweaks for Solaris and
853 * Made it possible to set the fire color in `xflame'.
854 * Made transparency work in TrueColor (for `goop' and
856 * Fixed a multi-head bug introduced by the virtual
858 Changes since 3.11: * Made it so that you can't scroll the screen while the
859 lock dialog is up (with XFree86 virtual viewports.)
860 * Fixed a bug in `flag' that caused bob's chin to get cut
861 off after a few iterations.
862 Changes since 3.10: * Made `xjack' be black-on-white-ish, so that it looks
863 less like a computer screen and more like the
864 typewritten paper it's supposed to be.
865 * New version of `pulsar'.
866 * Fixed Solaris compilation problem in `phosphor'.
867 * Made xscreensaver notice XFree86's virtual root window
868 hack, so that if the X server's root window is larger
869 than the monitor's displayable resolution, the screen
870 saver will limit itself to the area that actually
871 appears on the screen.
872 * Made the xscreensaver daemon do a better job of
873 picking the visual class that should be used for GL
874 programs. Less user intervention should be needed
875 now: you can use the logical visual name `GL' instead
876 of having to figure out by hand which one to use.
877 * Oops, the visual was defaulting to "best" instead of
878 "default", because the .xscreensaver file was not being
879 loaded quite early enough.
880 * Made configure figure out how to build icmp ping
881 support into the `sonar' hack automatically.
882 * Made warnings about not being able to read shadow
883 passwords not be printed if compiled with PAM support.
884 * Improved PAM startup diagnostics.
885 * Worked around the Solaris PAM bug that was causing
886 crashes there, so now PAM is turned on by default.
887 * Made configure detect the number of arguments that
888 pam_strerror() takes, since on Linux, this apparently
889 changed between 2.0 and 2.2, sigh.
890 * Made the /proc/interrupts kludge look for "PS/2 Mouse"
891 as well as "keyboard".
892 * Made xscreensaver notice when there has been a sudden
893 large jump in wall-clock time, and if so, lock right
894 away, instead of waiting for "lockTimeout" to expire
895 first. (Laptops need this for safer recovery from
897 * Added `-throttle' option to `xscreensaver-command'.
898 Changes since 3.09: * Added `phosphor', `xmatrix', and `pulsar' hacks.
899 * Fixed a bug in the color allocator that sometimes
900 caused `starfish' to fall back to monochrome.
901 * Reduced the amount of code that runs before root
902 privileges are disavowed: "normal" and "shadow"
903 passwords now do some initialization as root, but the
904 PAM and Kerberos authorization schemes will be
905 initialized while running as "nobody". Supposedly
906 this closes a potential security hole when using
908 * Added some more sanity checking to configure.
909 Changes since 3.08: * Added `compass', `squiral', `xflame', `wander',
910 `spotlight', and `critical' hacks.
911 * Added some new modes to `decayscreen'.
912 * Made `deluxe' work in monochrome.
913 * Generalized usage of the Double-Buffer server extension
914 in several hacks (`compass', `deluxe', `interference',
915 `kumppa', and `moire2'.)
916 * Fixed another visual-depth problem in `rd-bomb'.
917 * The screen saver will now defer blanking if neither
918 the keyboard nor the mouse could be grabbed. Instead,
919 it will just try again in a few minutes. This fixes
920 a bad interaction between xscreensaver and programs
921 like VMware that hold the mouse and keyboard grabbed
923 * Added a new erase mode (expanding spiral.)
924 Changes since 3.07: * Fixed some bugs in my port of `t3d'.
925 * Added `penetrate' and `deluxe' hacks.
926 * When linking against Motif 2.x, also link against XPM.
927 * Added support for using /proc/interrupts for idle
928 detection on Linux. Now xscreensaver shouldn't kick
929 in when the user is active on a non-X virtual console.
930 * Upgraded to autoconf 2.13.
931 Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
932 in properly; check for _Xsetlocale in -lXintl.)
933 * Portability fixes for sonar.c.
934 * Fixed a compilation problem when you have GL but don't
936 * Made configure notice when MesaGL requires -lpthread.
937 * Made `flame' ignore SIGFPE (not sure if this is the
938 right fix; it seems only to be needed on FreeBSD.)
939 * Kludged `rd-bomb' work on visuals that are of depth 24
940 but that *do not* support pixmaps of depth 32.
941 * Fixed `halo' to work properly in TrueColor.
942 * Changed `xscreensaver.spec' to install the hacks in
943 /usr/X11R6/lib/xscreensaver/ by default, since that's
944 where recent Red Hat distributions put them.
946 * Updated versions of `crystal', `hopalong', and `flow'
948 * Imported `demon' and `loop' modes from xlockmore.
949 Changes since 3.05: * Oops, the "default-n" visual descriptor was broken;
950 it was always installing a colormap if the
951 `installColormap' preference was set, meaning that
952 `xearth', `xv' and friends were using the wrong
953 colors on 8-bit systems.
954 * Turned off HAVE_PING in `sonar', since it compiles
955 on some Linux systems, but not others of similar
957 Changes since 3.04: * Fixed an off-by-1 in `distort'.
958 * Added `sonar' hack.
959 * New version of `glplanet' (with stars.)
960 * Made all hacks exit when you type `q' or `ESC' at them,
961 and made them obey the WM_DELETE_WINDOW ClientMessage.
962 * Fixed a nonfatal buffer overrun in lament (note:
963 lament still doesn't work with MesaGL 3.0: it dies in
964 lambda_textured_triangle1(), which is Mesa's bug, not
966 Changes since 3.03: * Added an `xscreensaver.spec' file, to make it easier
967 for other folks to generate RPMs.
968 * Made the password code work on HPUX in the situation
969 where: ``enhanced security'' is available; but not
970 used; but the user typed a password more than 8
971 characters long anyway. FTSOHPUX.
972 Changes since 3.02: * Made locking work when passwd aging is enabled.
973 * Added support for PAM (Pluggable Authentication
974 Modules.) It is still turned off by default, though,
975 since it doesn't seem to work on Solaris 2.6, and has
976 been behaving erratically on Red Hat 5.1.
977 * Made each possible authentication method be tried in
978 turn until one succeeds; this means that Kerberos is
979 being used, we will first check Kerberos, and if that
980 fails, will then consult the local password file.
982 * Save and restore the bits under the passwd dialog,
983 to avoid leaving a black rectangle behind when
984 unlocking is cancelled.
985 Changes since 3.01: * Not everyone has sys/select.h, sigh...
986 Changes since 3.00: * Some fixes to `reflect'.
988 * Made it log unsuccessful attempts to unlock the screen
990 * Fixed a bug where `xscreensaver-demo' could be seeing
991 a different programs list than `xscreensaver' did.
992 Changes since 2.34: * The xscreensaver daemon no longer links against Motif
993 or Athena: demo-mode and the preferences panel are no
994 longer built in to the daemon, but are now handled by
995 an external program, `xscreensaver-demo'.
996 (I decided that this, along with the recent addition
997 of the `.xscreensaver' config file, justified bumping
998 the version number to 3.00, since this is a fairly
999 major architectural change.)
1000 * Lines in the `*programs' resource may now begin with
1001 the character "-", meaning "don't run this hack."
1002 In this way, it's possible to disable a hack without
1003 throwing away the information about it (making it
1004 easier to change your mind later.) Eventually the
1005 preferences/demo mode GUI should represent this as a
1006 checkbox or something.
1007 * Fixed a short race condition where it was possible for
1008 xscreensaver to die with a BadWindow error if it was
1009 blanking the screen just as another window was being
1011 * Made it possible to disable specific modes in `bsod'.
1012 Changes since 2.33: * Fixed a bug that was making `pipes' generate way too
1013 many valves. Made the viewpoint in `pipes' be selected
1014 randomly instead of always being -10 degrees.
1015 * Fixed a bug in the XSHM code, in the case where the
1016 server supports the XSHM extension but is not the same
1017 machine as the client.
1018 * Made `rd-bomb' default to taking up the whole screen.
1019 * Made it not try to do fading/unfading if no PseudoColor
1021 * Initial attempt at supporting VT-locking (doesn't work
1023 * Eliminated the `captureStdout' resource; now
1024 `captureStderr' controls both streams.
1025 * Added `-capture-stderr' and `-no-capture-stderr'
1026 command-line arguments.
1027 * Added `glplanet' hack.
1028 * When a hack is selected with `xscreensaver-command
1029 -select', that hack will be used until further notice
1030 (until the saver turns off, or another activation
1032 Changes since 2.32: * Made `xscreensaver-command' print error messages:
1033 the xscreensaver daemon now responds to ClientMessage
1034 events by writing a response message on a window
1035 property, instead of just writing to its stderr.
1036 * Made the ~/.xscreensaver file be automatically reloaded
1037 when the file date changes.
1038 * The password dialog and splash screen no longer depend
1039 on Motif or Athena. This should clear up a number of
1040 focus problems, and is the first step on the path
1041 toward moving all of the Motif/Athena/whatever code
1042 out of the xscreensaver daemon, and into external
1044 * Don't complain about LessTif 0.86 any more, since the
1045 new password dialog makes that problem go away.
1046 * Configure tweaks for Irix 6.5, SunOS 5.something.
1047 * New `-reflect' option to `distort'.
1048 Changes since 2.31: * Added reading and writing of a ~/.xscreensaver file,
1049 so that the Preferences panel can save its settings.
1050 * New version of `rubik'.
1051 * Added `-select N' argument to `xscreensaver-command'.
1052 * Oops, left out some of the `bubbles3d' files...
1053 Changes since 2.30: * The cursor was invisible in the password dialog. Fixed.
1054 * Made configure warn against MesaGL 2.6.
1055 * Fixed X error at startup when using non-default visual.
1056 * New version of `crystal', `ant', and `atlantis' from
1058 * New hack, `bubble3d'.
1059 * Added some new modes to `bsod'.
1060 Changes since 2.29: * Changed the order in which -lSM and -lICE are linked
1061 to be after Motif instead of before (Lesstif on Irix
1063 Changes since 2.28: * Work around a bash bug in configure.
1064 * Tweaked HPUX paths again. FTSOHPUX.
1065 * Made configure recommend against LessTif 0.86, due
1066 to a bug in that version that causes a security hole
1067 in the screen locking code. LessTif 0.87 will fix it.
1068 * Made all of the `--with' options to `configure' accept
1069 a directory option as well (so that --with-motif=/FOO
1070 will add -I/FOO/include -L/FOO/lib). I believe this is
1071 the Configure Party Line of how do to such things.
1072 * Fixed a bug where the mouse was left un-grabbed
1073 after the first time the graphics hack was changed
1074 (simplified all of the mouse-grabbing logic.)
1075 * Maybe possibly perhaps made `vidwhacker' really not
1076 leave stray xv windows around. This time for sure.
1077 * Added a new erase mode (random dots fizzling out.)
1078 * Added `-prefs' argument to `xscreensaver-command',
1079 that brings up the Preferences dialog directly (it
1080 seems that nobody ever noticed the `Preferences' button
1081 on the Demo Mode dialog, maybe this will help.)
1082 * Added a splash screen. Turn it off with *splash:false.
1083 Changes since 2.27: * Better macsbug text in `bsod'.
1084 * New version of `distort' with many new modes.
1085 * Plugged a leak in `coral'.
1086 * Tweaked configure for HPUX.
1087 * Removed some compiler warnings.
1088 * More consistent usage of stderr versus stdout.
1089 * More diagnostics should an X error occur.
1090 * Fixed a possible crash in SGI-specific unfading code.
1091 Changes since 2.26: * Improved version of `distort'.
1092 * Made `lament' compile against OpenGL 1.0 (though it
1093 still requires 1.1 to work properly.)
1094 * Updated my email address and home page.
1095 Changes since 2.24: * Improved motion in `rd-bomb'.
1096 * Added XSHM (shared memory extension) support to the
1097 `distort', `interference', `moire', `rd-bomb', and
1098 `swirl' hacks, which speeds them up a bit.
1099 * Added `lament' hack.
1100 Changes since 2.23: * Tweaked the order of the -L options again.
1101 * Cleaned up configure's `--help' message.
1102 * Added `kumppa' hack.
1103 * Smarter maze-solving algorithm in `maze'.
1104 * Took `xlyap' out of the default list of hacks, since
1105 it's just incredibly buggy (and slow.) Maybe someday
1106 someone will fix it...
1107 * Added `distort' hack, but didn't add it to the default
1108 list (yet) because it's still too slow.
1109 * Made the Athena demo dialog look more like the Motif
1110 version; it has a text-entry field now, too.
1111 * Made the Athena password dialog echo asterisks, like
1112 Motif does, instead of using a flyspeck font.
1113 * Some random configure tweaks.
1114 * Added a `timestamp' resource that makes the `-verbose'
1115 messages include the time at which they were printed.
1116 Changes since 2.22: * The fix for SGI's ``scheme'' nonsense broke things, and
1117 let the user's "*background" resource show through.
1118 Fixed it in a different way.
1119 Changes since 2.21: * Added support for the DPMS server extension (Display
1120 Power Management System.)
1121 * Made configure advertize the `--enable-subdir' option a
1122 little more, since that seemed to cause some people
1123 stress. Also, made that directory be built into the
1124 xscreensaver executable, as a hardcoded prefix to
1125 $PATH. (Might help, shouldn't hurt.)
1126 * Made configure prefer the two-arg gettimeofday to the
1127 one-arg version, since AIX doesn't have any prototypes.
1128 * Made it work with Xaw3d (the 3D Athena library.)
1129 * Made `make install' create directories as necessary.
1130 * New version of lmorph from Sverre.
1131 * Added `crystal' and `discreet' hacks from xlockmore.
1132 * Added a new mode to `bsod'.
1133 Changes since 2.20: * Made `xscreensaver-command -time' use different words.
1134 (It now describes the two states as "screen blanked
1135 since..." and "screen non-blanked since..." instead of
1136 "active since..." and "inactive since..." which a lot
1137 of people interpreted as meaning the opposite of what
1139 * Improved some error messages, in the hopes of making
1140 the distinction between the xscreensaver and
1141 xscreensaver-command programs more obvious.
1142 * Rewrote (and reorganized) parts of the xscreensaver and
1143 xscreensaver-command manual pages.
1144 * Renamed xscreensaver's `-lock' command-line option to
1145 be `-lock-mode', to avoid confusion with the `-lock'
1146 option to xscreensaver-command, which does a totally
1148 * Removed xscreensaver's `-demo' command-line option for
1149 a similar reason; use `xscreensaver-command -demo'
1151 * Disabled SGI's ``scheme'' nonsense in a better way than
1152 fully-qualifying the background colors in every single
1154 * Fixed some other minor cosmetic problems when *sgiMode
1156 * Fixed an X error in `bsod -root' (how ironic...)
1157 Changes since 2.19: * Fixed a bug that caused the mouse to sometimes not be
1158 grabbed properly (meaning the window manager menu could
1159 pop up over the demo-mode display.)
1160 * Fixed a bug that made the stderr output sometimes get
1162 * Fixed a bug that made the demo-mode scrollbar move too
1164 * Protected against a possible buffer overflow.
1165 * Made `vidwhacker' not leave stray xv windows around.
1166 * New version of `ant' so that Bagley doesn't calve.
1167 * Make configure on AIX get XShm from the right library.
1168 Changes since 2.18: * One file was missing from the tar file. Fixed.
1169 Changes since 2.17: * Oops, atlantis wasn't being built by default. Fixed.
1170 * Added `epicycle' hack.
1171 * Added `interference' hack.
1172 * Added `truchet' hack.
1173 * Added `bsod' hack.
1174 * Added some new modes to `vidwhacker'.
1175 Changes since 2.16: * Added a -window-id argument to most hacks, so that they
1176 can draw on arbitrary externally-provided windows.
1177 * Synched with xlockmore 4.11a01.
1178 * Added `flow' hack.
1179 * Added `atlantis' GL hack.
1180 * Renamed `puzzle' hack to `jigsaw', since xlock already
1181 had a different mode called `puzzle'.
1182 * Made it self-configure properly when Motif 2.1.0 is
1183 being used (requires -lXp now, sigh...)
1184 Changes since 2.15: * Made `flag' able to do XPM images.
1185 * New look for the xscreensaver logo (`xroger').
1186 * Fixed compilation error on Suns with adjunct passwords.
1187 * Got multi-architecture builds working again.
1188 * Some configure tweaks for building on HPUX and Solaris.
1189 * Fixed bug in decayscreen.

1194 * Tweaked `erase.c' some more.
1195 * Made unfading a bit smoother.
1196 * Added `vidwhacker' hack (not installed by default.)
1197 * Added `stairs' hack.
1198 * Split `escher' into `cage' and `moebius', as per
1200 * Changed subprocess handling to use sigaction() instead
1201 of signal() if it's available (this is necessary for
1202 SCO but should work fine on other systems too.)
1203 * Various other tweaks.
1204 Changes since 2.13: * Better fix for the Motif drag-and-die lossage.
1205 * Put in some kludges to work around a LessTif bug.
1206 * XScreenSaver is known to work with LessTif 0.82 now.
1207 * Made fading work on high-end SGI video hardware.
1208 * Fixed another SGI-specific bug in screen grabbing;
1209 will the madness never cease?
1210 * Fixed another crash in `xlyap'.
1211 Changes since 2.12: * Made `decayscreen' do directions other than down.
1212 * Improved `puzzle'.
1213 * Fixed a crash in `xlyap'.
1214 * Added CDE info to the man page, removed `cde.txt'.
1215 * Configure tweaks for Zippy.
1216 * Turned off the signal handling in `bubbles' because
1217 it was sometimes failing to die.
1218 * Added `hacks/xscreensaver-sgigl.c' to make it possible
1219 to run SGI's ElectroPaint hack (/usr/demos/bin/ep)
1220 with xscreensaver. Finally!
1221 * Fixed a buffer overrun in the locking code that some
1222 wily, malicious cracker must have slipped in.
1223 * Disabled Motif drag-and-drool in the dialog box
1224 buttons, since it's broken in some old versions of
1226 Changes since 2.11: * Added `README.debugging'.
1227 * Added `puzzle' hack.
1228 * Added `xlyap' hack.
1229 * Added `default-n' as a visual name, so that one can
1230 have -install on by default, but turn it off for
1231 certain poorly-behaved hacks (like xv.)
1232 * Added support for grabbing frames of external video
1233 (on SGI) to the screen-grabbing hacks (decayscreen,
1234 slidescreen, slip, blitspin, and puzzle.)
1235 * Improved look of tiles in `slidescreen'; fixed its
1236 color allocation problem.
1237 Changes since 2.10: * Tweaked `blitspin', added it to the default list.
1238 * Added `lissie', `mountain', `triangle', `worm',
1239 `rotor', and `ant' from xlockmore.
1240 * Updated `sierpinski', `galaxy', and `lisa'.
1241 * Thickened the lines in `braid' and `lmorph'.
1242 * Updated VMS makefiles.
1243 * Renamed `fract' to `vines'.
1244 * Added `xjack' hack.
1245 * Made a few more hacks use erase.c, and added a few
1247 * Fixed compilation problem with Sun's version of OpenGL.
1248 * Added ability to use sigaction() instead of signal()
1249 to work around a SCO kernel bug.

1251 * Configure tweaks for *BSD.
1252 Changes since 2.07: * New hacks `rd-bomb' and `coral'.

1265 configure to detect the extra-random -Xss library.
1266 Changes since 2.03: * HP configure tweaks. Detect and warn about LessTif.
1267 * Fixed low-color behavior of `goop', `pyro', `starfish',
1268 `greynetic', `flame', `halo', and `moire'.
1269 Changes since 2.02: * Fixed flicker in `pipes'. Fixed 3d in `bouboule'.
1270 * Added `munch' hack.
1271 * Added basic dependencies to the Makefile.in files.
1272 Changes since 2.01: * Fixes for compiling with the MIT saver extension.
1273 * Made the yow/fortune program be a configure option.
1274 * Various configure tweaks.
1275 Changes since 2.00: * Added `goop' and `starfish' hacks.

1277 * Made `attraction' use the new colormap allocator.
1278 * Added better $PATH diagnostics.
1279 * There was a bug in frand! Color selection should be
1281 Changes since 1.34: * Converted to use `configure' instead of `imake'.

1284 * Made the stderr text use overlay planes, if possible.
1285 * Reworked the xlockmore compatibility stuff again.
1286 * Added `gears', `superquadrics', `escher', `pipes',
1287 and `sproingies' hacks (depend on OpenGL.)
1288 Changes since 1.33: * Fixed some bugs, made fading be a little smoother.
1289 Changes since 1.32: * Made it work with multi-headed displays.
1290 * Generalized sub-process management (Unix sucks!)
1291 * Added interactive mouse frobbing to Julia.
1292 * Added (untested) support for HPUX shadow passwords.
1293 * Made normal non-shadow passwords be checked if the
1294 shadow passwords aren't accessible for some reason.
1295 Changes since 1.31: * Removed *colorPrograms and *monoPrograms resources:
1296 made it possible to specify the desired visual on a
1298 * Cleaned up / restructured the driver: no more globals.
1299 * Made the Motif and Athena dialogs share more code.
1300 * Probably fixed some Athena colormap-installation bugs.
1301 * Fixed screen grabbing (cmap) on SGI 12-bit PseudoColor.
1302 * Fixed divide-by-zero in bright random colormaps.
1303 * Added an improved version of xlock's `flag' hack.
1304 * Made unfading work better, and not flicker on SGIs.

1309 * Made `blitspin' able to grab an image off the screen.
1310 * Ported `swirl' and `bouboule' hacks from xlockmore.
1311 * Made the driver more careful about not leaving bits on
1312 the screen, or allowing other windows to raise
1313 themselves: it now re-blanks the screen every so often.
1314 * Added `-time' option to `xscreensaver-command'.
1315 * Improved SGI screen-grabbing some more: now it can grab
1316 TrueColor screens into PseudoColor windows and have the
1317 colors still come out semi-reasonably.
1318 Changes since 1.29: * Made `slidescreen' and `decayscreen' work better on
1319 SGIs when windows of different visuals are present, by
1320 using the XReadDisplay() extension to get a true 24-bit
1321 image out of the frame buffer.
1322 * Made `noseguy' be in color, if compiled with XPM.
1323 * Ported `braid', `drift', `fract', `galaxy', `grav',
1324 `ifs', `julia', `laser', `lightning', `penrose',
1325 `sierpinski', `slip', `spiral', and `strange' hacks
1327 * Merged `hopalong' hack with a more recent version.
1329 Changes since 1.27: * Added `deco', `moire', and `kaleidescope' hacks.
1330 * Merged in support for non-Motif locking and demo mode.
1331 * Made `blitspin' and `bubbles' work in TrueColor.
1332 * Fixed a stupid bug I introduced in `imsmap'.
1333 * Added `poly' and `gravity' options to `qix'.
1334 Changes since 1.26: * Added support for SGI SCREEN_SAVER extension.
1335 * Made `fade' and `unfade' work on 8-bit SGIs.
1336 * Made the dialog boxes more Motify.
1337 * Added `bubbles' hack.

1339 * Added viscosity and mouse-control to attraction.
1340 * Fixed possible bad color choices in qix and attraction.
1341 * Added ramp-mode to halo.
1342 * Added a new RNG, which is faster and more portable
1343 than using the RNG in libc.
1344 * Made locking work on SCO.
1345 * Various other minor tweaks that I don't remember.
1346 Changes since 1.24: * Made it capture the stdout/stderr of its subprocesses
1347 and present them on the screensaver window itself.
1348 * Made demo mode work correctly with non-default visuals
1349 and color maps, instead of always using the defaults.
1350 * Added -visual argument to all included screenhacks.
1351 * Support for the R6 MIT-SCREEN-SAVER server extension.
1352 * Made the demo mode list scroll properly.
1353 * Added `pedal' hack.
1354 Changes since 1.23: * Fixed some private-colormap oddities in slidescreen,
1355 decayscreen, and xroger. Fixed apparent conservation-
1356 of-mass problem in pyro; made the shrapnel round.
1357 Changes since 1.22: * Minor tweaks for IRIX5; fixed locking race condition.
1358 Changes since 1.21: * Minor tweaks for X11R6.
1359 * Fixes for non-default visuals.
1360 Changes since 1.20: * Fixed bug in color blitspin; added default image.
1361 * Added diagnostics to noseguy. Fixed off-by-one
1362 error in flame. Added some missing casts.

1374 * Moved the hacks into their own directory.
1375 * Made all `time' parameters accept the 00:00:00 syntax,
1376 so that even the parameters which are normally read as
1377 minutes can be specified in seconds.
1378 * Added colormap cycling to `imsmap'.
1379 * Made hyper work with K&R compilers.
1380 Changes since 1.13: * Added `orbit' option to `attraction' hack.

1386 Changes since 1.4: * Works when run from XDM before anyone logs in.
1388 * Can use `xv' as a slideshow without using up colormap
1389 entries while the screen is not blanked.
1390 * Fixed a BadDrawable error in non-XIdle mode.
1391 * Added `blitspin' and `imsmap'.
1392 Changes since 1.0: * Current list of included hacks is now: qix, helix,
1393 rorschach, attraction, greynetic, rocks, pyro,
1394 hopalong, and noseguy.
