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

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

137 entering numbers that are out of range.
138 * Added "Reset to Defaults" button on X11.
139 * Added relevant Wikipedia links to many of the screen
141 * All hacks support the `-fps' option, not just GL ones.
142 * The `-fps' option now shows CPU load.
143 Changes since 5.05: * Xinerama/RANDR fixes: this time for sure. It should
144 now work to add/remove monitors or resize screens at
146 * New hack, `skytentacles'.
147 * New version of `gleidescope'.
148 * Added the `-log' option to the xscreensaver daemon,
149 since a truly shocking number of Linux users seem to
150 have no idea how to redirect output to a file.
151 * Added `-duration' arg to most image-loading hacks,
152 so that they pick a new image every few minutes.
153 * Added an ATM crash to BSOD.
154 Changes since 5.04: * New hacks, `cubicgrid', `hypnowheel', and
155 `lcdscrub' (which isn't really a screen saver).

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

173 fallout from the recent PAM changes...)
174 * New hacks, `moebiusgears', `abstractile', and
176 * Rewrote `gears' to use better (involute) gear models,
177 and to be more random.
178 * Minor updates to `cwaves', `voronoi', `deco',

195 `flipflop', `flipscreen3d', `fliptext', and `carousel'.
196 * Enabled multi-threaded OpenGL on MacOS.

200 * `xflame' and `flag' ignore bitmap option on MacOS.
201 * `speedmine' prefs work on MacOS.
202 * Better explosions in `boxed'.

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

393 `blocktube', and `glmatrix'.
394 * Updates to `cloudlife', `engine', `xmatrix', and
396 * Rewrote `glslideshow': it should work on somewhat
397 wimpier video cards now.
398 * Various portability tweaks.
399 Changes since 4.09: * New hacks, `cloudlife' and `klein'.
400 * Added Apple ][+, HPUX, and OS/390 sessions to BSOD.
401 * Added some Matrix Reloaded text to `xmatrix'.
402 * Updates to `webcollage', `eruption', `jigglypuff',
403 `metaballs', and `endgame'.
404 * Completely ignore the `memoryLimit' setting now,
405 since it was still causing people GL grief.
406 * Various minor fixes.
407 Changes since 4.08: * New hacks, `flyingtoasters', `bouncingcow',
408 `jigglypuff', and `glslideshow'.
409 * More models in `engine'.
410 * Rewrote `xscreensaver-getimage' to remove reliance on
411 external image loaders (xv, chbg, xloadimage, etc.)
412 and to reduce flicker when loading files.
413 * Made `gflux' and `flipscreen3d' be mouse-spinnable.
414 Changes since 4.07: * New hacks, `atunnels' and `piecewise'.
415 * Physics improvement in `fluidballs'.
416 * Various fixes for XDarwin systems (X11 on MacOS X.)
417 * Added -clock option to `barcode'.
418 * Minor fixes to `endgame', `flurry', `flipscreen3d',
420 Changes since 4.06: * New hacks, `flurry', `metaballs', `eruption',
421 `popsquares', and `barcode'.
422 * Minor updates to `maze' for high density mazes.
423 * Added double buffering to `fluidballs' and `whirlygig'.
424 * Bug fixes for running xscreensaver to a remote XFree86
425 display (which nobody would ever do...)
426 * Updated `webcollage' (faster Alta Vista searching.)
427 * Updated `glplanet' so the sun sets in the west.
428 * Updated `sproingies' with smooth, unsegmented surfaces.
429 * Fixed Perl version-sensitivity in
430 `xscreensaver-getimage-file'.
431 * Fixed GTK2 scrolling bug in `xscreensaver-demo'.
432 Changes since 4.05: * New hack, `glblur' (disabled by default, since it
433 requires fast OpenGL texture support.)
434 * New hack, `halftone'.
435 * Updates to `endgame', `queens', `bumps', `glplanet',
436 `engine', and `circuit'.
437 * New version of `menger' that uses far fewer polygons.
438 * Fixed minor bug in `critical' that could cause some
439 bogus X servers to crash.
440 * Better labels in `molecule': the labels now appear to
441 be attached to the atoms, instead of floating in front
443 * Fixed bug that could rarely cause GL hacks to fail to
444 double-buffer (causing intermittent flickering.)
445 * Fixed a relative-URL-parsing bug in `webcollage'.
446 * Fixed a bug that (sometimes) caused the window manager
447 close box to kill `xscreensaver-demo' with a crash
448 instead of a graceful exit.
449 * Updated xscreensaver.pam to the Red Hat 7.3 way.
450 * More Gnome2-related configure crap.
451 * Updated to latest `config.guess' and `config.sub'.
452 * Fixed occasional core dump in `distort'.
453 * Added a Linux fsck failure and kernel panic to `bsod'.
454 * Added MacOS X kernel panic to `bsod'.
455 * Fixed a bug in `bsod' (all bsod bugs are ironic.)
456 * Fixed a bug that caused `xscreensaver-gl-helper' to
457 print a nonsense visual ID with some versions of
458 `printf': this could cause GL programs to display
459 incorrectly (e.g., flickery.)
460 Changes since 4.04: * More `configure' tweaks to try and get things working
461 on systems that both Gtk 1.x and 2.x installed.
462 * New hack, `endgame'.
463 * Minor updates to `gltext'.
464 Changes since 4.03: * Support for GTK 2.x / GNOME 2.x.
465 * The `configure' script will now use `pkg-config' if
466 you have it, in preference to `gtk-config', etc.
467 * New hacks, `lavalite', `queens', and `anemone'.
468 * Minor updates to `spheremonics', `gltext', `xmatrix'.
469 * You can use the mouse to manually spin most of the GL
470 hacks now (when they are displaying in a window.)
471 * Fixed a bug in `webcollage' (due to recent Alta Vista
472 url changes) that was causing it to try and load
473 incorrect image URLs.
474 * Made `xscreensaver-getimage' use gdk_pixbuf if it is
475 available: this means that those hacks that load images
476 will no longer rely on "xv", "xloadimage", etc. This
477 will close a race condition that could sometimes cause
478 your desktop background to be changed; and also makes
479 it possible for those programs to operate on image
480 files when running in windowed mode.
481 * `webcollage' can now be used in conjunction with
482 `driftnet' to display images snooped from your local
483 ethernet instead of obtained from search engines.
484 * Added man pages for all the hacks that didn't have
486 Changes since 4.02: * New hack, `spheremonics'.
487 * Minor updates to `webcollage', `cage', `moebius',
488 `morph3d', `boxed', `circuit', and `helix'.
489 * `pulsar' and `extrusion' can now load texture JPEGs.
490 * `rubik' now does non-square cubes.
491 * `fluidballs' now does various sizes of balls.
492 * `menger' and `sierpinski3d' now also show polygon
494 * `molecule' displays real subscripts in the formulae.
495 * GTK internationalization/localization support.
496 * Better detection of the various versions of libxml.
497 * Upgraded to autoconf 2.53 (from 2.13.)
498 Changes since 4.01: * Plugged a few minor leaks in `xscreensaver' and
500 * New hacks, `cubenetic' and `fluidballs'.
502 * Fixed sphere projection error in `glplanet'; installed
503 a better image of earth.
504 * Added Win2K and MacOS 1 crashes to `bsod'.
505 * Put back previous (better) version of `forest' that
506 was accidentially downgraded in the last release.
507 * New version of `bumps'.
508 * Made FPS computation in GL hacks more efficient: it
509 will influence the results less, thus resulting in
510 higher (but more accurate) reported frame rates.
511 Changes since 4.00: * New hacks: `twang', `glsnake', `boxed', `sballs',
513 * New hacks `apollonian', `euler2d', `juggle',
514 `polyominoes' and `thornbird', from xlockmore.
515 * Merged recent xlockmore changes into `ant', `braid',
516 `demon', `discrete', `drift', `fadeplot', `forest',
517 `grav', `hopalong', `ifs', `laser', `lightning',
518 `lisa', `lissie', `loop', `mountain', `penrose',
519 `rotor', `sierpinski', `slip', `sphere', `spiral',
520 `strange', and `vines'.
521 * Fixed the `gltext' bug that sometimes caused
522 horizontal lines to vanish again. This time for sure.
523 * Sped up `webcollage' by adding a C helper program to
524 replace the PPM pipeline. It also pastes images
525 semi-transparently now.
526 * Added support for the gdk_pixbuf library: if this lib
527 is available, then `blitspin', `xflame', and `flag'
528 can load GIF, JPEG, and PNG images in addition to XPM
530 * Fixed a rare race condition where the desktop-grabbing
531 hacks could sometimes leave the screen wedged, if the
532 user moved the mouse exactly when they were grabbing
533 the screen image (it would un-wedge the next time the
534 saver timed out or was activated.)
535 * Fixed incorrect colors in the screen-grabbing GL hacks
536 (`gflux' and `flipscreen3d'.)
537 * Made SIGHUP restart the daemon process (though using
538 `xscreensaver-command -restart' is still the preferred
540 * Tweaks to `xspirograph'.
541 * Minor configure and portability tweaks.
542 Changes since 3.34: * Redesigned `xscreensaver-demo' GUI: it now includes
543 small-preview and per-hack configuration dialogs.
544 * Added three new modes of operation: `One Screen Saver',
545 `Blank Screen', and `Don't Blank' (in addition to the
546 historical `Random Screen Saver').
547 * Configure now defaults to installing the hacks in
548 <prefix>/lib/xscreensaver/ instead of <prefix>/bin/.
549 (Most distros already did it this way.)
550 * New GL hacks, `menger', `engine', `flipscreen3d'.
551 * Made `sierpinski3d' be more colorful.
552 * New versions of `xmatrix' and `nerverot'.
553 * Fixed a bug in `starwars' that made the font be drawn
554 with thin lines in -root mode.
555 * Fixed a bad colormap bug in `crystal' that could make
556 *subsequent* hacks malfunction!
557 * Made `gflux' able to grab screen images (`-mode grab').
558 * Updated `webcollage' for recent search engine changes.
559 * Removed most command-line options to `xscreensaver':
560 just edit the ~/.xscreensaver file instead.
561 * Improved behavior on multi-screen and Xinerama systems:
562 the mouse now stays on the screen where the user left
563 it, and the password and splash dialogs always appear
564 on the screen that has the mouse.
565 * Made the splash dialog use more Gtk-like colors;
566 made it have only two buttons, "Settings" and "Help".
567 * Made `sonar' understand `.ssh/known_hosts2' format
568 files, and be better about stripping out illegal
570 Changes since 3.33: * Turned `memoryLimit' off by default, sigh. Apparently
571 some versions of the GL libraries (appear to) allocate
572 hundreds of megs for every GL program, so `memoryLimit'
573 was causing GL programs to malfunction or crash on
575 * Improved fading on TrueColor XFree86 4.1.x systems.
576 * New GL hack, `circuit'.
577 * Added `fuzz' mode to `decayscreen'.
578 * New version of `whirlygig'.
579 * Added links to `xplanet' and `sphereEversion'.
580 * Fixed rare race condition that could make `sonar' hang.
581 * Fixed potential crash in `speedmine'.
582 * Made `xscreensaver-demo' not crash when imageDirectory
583 was set to a non-existent directory.
584 * Made `xscreensaver-getimage-video' invoke XawTV's
585 `streamer' program better.
586 * Made `phosphor' and `starwars' deal with CR, LF,
587 or CRLF line endings.
588 * Changes for Cygwin compilation environments.
589 * Made `sonar' compile on systems that can't ping.
590 * Configure changes for HPUX 10.20.
591 * Made PAM code work on Red Had 4.2 systems.
592 * Made `xscreensaver-command -deactivate' work when the
593 saver is not active: what that does is reset the idle
594 timer, as if keyboard input had been detected. This
595 was added for the benefit of people writing DVD-playing
596 software: they can now prevent the screensaver from
597 kicking in by sending a -deactivate message once a
598 minute while the movie is playing and not paused.
599 * Various minor portability tweaks.
600 Changes since 3.32: * New hacks, `speedmine' and `whirlygig'.
601 * Sped up `pyro', made the explosions look a bit better.
602 * Added better stars to `glplanet' and `starwars'.
603 * Many internal changes to `webcollage'.
604 * Some new options to `attraction'.
605 * Minor fix to `noseguy' to avoid un-erased pixels.
606 * Rewrote the screen-eraser effects so that they complete
607 in the same amount of time regardless of how slow
608 your X server is (some of them were glacial on servers
610 * Fixed a potential free memory reference that could
611 sometimes cause a crash at startup.
612 * Possibly fixed a problem that could cause the daemon
613 to crash with an X error. I was never able to
614 reproduce this problem, but I think I might have
615 figured out what caused it.
616 * Worked around a problem that caused PAM authentication
617 to fail on some Red Hat 7.x systems.
618 * Added a `memoryLimit' parameter that controls the
619 amount of memory a graphics hack may allocate: if they
620 try to allocate more than this, malloc() will fail
621 (and they will exit or (safely) crash, rather than
622 hogging memory.) Default is 50M.
623 * Made `gnome-help-browser' be the default way to display
624 man pages in `xscreensaver-demo', if running on a
626 Changes since 3.31: * The image-manipulating hacks (`slidescreen', etc.) can
627 now operate on randomly chosen image files from disk,
628 or on frames captured from the system's video input,
629 instead of (or in addition to) manipulating images of
631 * Rewrote `vidwhacker' to use the new image-grabbing
633 * Made fading work on TrueColor XFree86 4.x systems.
634 * Fixed a subtle rendering bug in `atlantis' (the fish
636 * Made `atlantis' have a texture simulating light
637 reflections from the surface of the ocean.
638 * Fixed up label placement in `molecule'.
639 * Better color bars in `xteevee'.
640 * Made `install-strip' not try to strip scripts.
641 Changes since 3.30: * Put in more sensible defaults for DPMS, and updated
642 the documentation to reflect the fact that all your
643 DPMS settings are now belong to xscreensaver.
644 * Fixed the `xscreensaver.spec' file so that `--force'
646 * New versions of `rotzoomer' and `nerverot'.
647 * Fixed an OSF/1 compilation problem in `molecule'.
648 Changes since 3.29: * New hacks, `molecule', `dangerball', and `rotzoomer'.
649 * New version of `gflux'.
650 * Made `gltext' able to display the current time.
651 * Fixed a floating-point-precision problem in `gltext'
652 that sometimes caused horizontal lines to vanish.
653 * Removed the `-window-id' option from the hacks:
654 it never worked right, and was unnecessary.
655 * Made the `starwars' hack use thicker lines, antialias
656 the text, and fade out at the far edge instead of just
658 * Fixed an SHM segment leak in `moire'.
659 Changes since 3.28: * Better rendering of the new logo.
660 * New hack, `gltext'.
661 * Added `-planetary' option to `gears', to draw a
662 different kind of gear system.
663 * Made motion and rotation be smoother in `gears',
664 `glplanet', `moebius', `rubik', and `sierpinski3d'.
665 * Improved coloration in `sierpinski3d'.
666 * Made the GL hacks react to window size changes.
667 * Made most of the GL hacks take a -fps option (like
668 `pulsar' did), so you can use them to benchmark your
670 * Fixed the previous fix to `sonar'.
671 * Minor fix to `nerverot'.
672 Made sonar able to ping hosts on DEC OSF1.
673 * Eliminated a bogus "didn't get enough colors" warning
674 in some of the hacks.
675 Changes since 3.27: * New logo for xscreensaver!
676 * New hacks, `starwars' and `stonerview'.
677 * Made the motion of the bouncing ball in `stairs' be a
679 * Made newly-added screenhacks be added to .xscreensaver
680 automatically: if there are hacks in the app-defaults
681 file that are not also in ~/.xscreensaver, they will
682 be added to the end of the list.
683 * Redid the `Screensaver Options' part of the control
684 panel; xscreensaver now lets you configure your DPMS
686 * Fixed some Makefile problems with non-GL builds.
687 * Fixed detection of MesaGL for version 3.3.
688 * Better workaround to Red Hat 7.0's broken gcc.
689 * Added Sparc Solaris kernel panic to `bsod'.
690 Changes since 3.26: * New hacks: `zoom' and `whirlwindwarp'.
691 * Fixed a free-memory-reference bug in `sonar'.
692 * Better error handling when there are no suitable GL
694 * Added diagnostic dialog when xscreensaver-demo is
695 unable to launch xscreensaver (e.g., when running as
697 * Fixed a bug that caused screenhack argument changes
698 to be ignored when xscreensaver-demo was running as
699 root (if "root" and "nobody" have different home
701 * Made the programs default to ":0" if $DISPLAY is unset.
702 * Made the `-verbose' output include information about
703 which server extensions were supported at compile time.
704 * Worked around Red Hat 7.0's broken gcc 2.96.
705 * Updated default delays on the GL hacks to look better
706 on machines with super-fast 3D hardware.
707 * Install `screensaver-properties-capplet' to work around
708 the usual egregious GNOME lossage.
709 Changes since 3.25: * Added "enabled" checkboxes in the list of hacks in
710 xscreensaver-demo (Gtk version only.)
711 * New hacks `hyperball', `xrayswarm', and `gflux'.
712 * New versions of `nerverot', `galaxy', and `hypercube'.
713 * Small fixes to `phosphor', `shadebobs', `xflame',
715 * Added external helper program `xscreensaver-gl-helper'
716 to figure out which X visual to use for OpenGL
718 * Configure updates for XFree86 4.0, and for BSD.
719 * Made it be more tolerant of bogus /etc/group files.
720 * When installing the PAM config file, first try to just
721 copy an existing "xdm" or "login" config file, so that
722 xscreensaver does authentication in the same way as the
724 Changes since 3.24: * New hack, `nerverot'.
725 * Added BSD kernel panic to `bsod'.
726 * New version of `shadebobs'.
727 * New version of `petri'.
728 * Updated `webcollage' to handle recent Altavista URL
729 format changes; made it search the AP photo gallery.
730 * Revamped command-line options of `sonar' and made it
731 properly handle subnets.
732 * The `bubbles' hack can now trickle up or down the
734 * The `xsublim' hack can now read its text from programs.
735 * Support for GLE version 3 in `extrusion'.
736 * Fixed compilation problems in `maze'.
737 * Fixed a rare crash in `flow'.
738 * Fixes for minor installation problems.
739 Changes since 3.23: * Added `-ignorant' option to `maze' hack.
740 * Updates to `critical', `bsod', `xflame', and `flow'.
741 * Added support for Kerberos 5 (via its Kerberos 4
742 compatibility layer.)
743 * Fixed a bad leak in `xteevee'.
744 * Updated `webcollage' to handle recent Altavista URL
746 * Removed xscreensaver-demo's `Ok' and `Cancel' buttons,
747 since they were confusing people: all changes are now
749 * Made xscreensaver-demo install itself into the Gnome
751 Changes since 3.22: * Fixed some misplaced text fields in the Motif version
752 of xscreensaver-demo; fixed a crash in the Gtk version
753 that would happen if the programs list was empty.
754 * Fixed a recently-introduced bug in `pulsar'.
755 * Made `sierpinski3d' use solid tetrahedrons instead of
757 * Added `-trace' option to `xmatrix'.
758 * Added new hacks `xteevee' and `xspirograph'.
759 Changes since 3.21: * Fixed some bugs in xscreensaver-demo.
760 * Rewrote the Motif version of xscreensaver-demo to
761 match the new Gtk version.
762 * The Athena toolkit is no longer supported.
763 Changes since 3.20: * Tweaked the xscreensaver-demo UI (Gtk only.)
764 * Fixed a few visual selection bugs. I think the proper
765 GL visual should be used with nVidia systems now.
766 * Made the Makefiles obey $install_prefix.
767 * Made the `xscreensaver.spec' file able to generate both
768 GL and non-GL packages simultaneously.
769 Changes since 3.19: * Added new hacks `ripples' and `sierpinski3d'.
770 * Made `xscreensaver-command -exit' be silent when no
771 screen saver was running (instead of complaining.)
772 * Made `webcollage' and `vidwhacker' use `xloadimage'
773 when available (in addition to `xli' and `xv'.)
774 * Improved memory usage in `petri' and gave it a hard
775 cap on how much memory it can allocate.
776 * Added `-watch' option to `xscreensaver-command'.
777 * Made `xscreensaver-demo' come up with the
778 most-recently-run hack selected by default.
779 * Rewrote the Gtk version of `xscreensaver-demo'.
780 It's a lot easier to use now.
781 * Extended the format of the programs list in the
782 .xscreensaver file, for the benefit of the new
783 capabilities of `xscreensaver-demo'.
784 NOTE: you might want to delete your ~/.xscreensaver
785 file and allow it to be re-created! The old one
786 should still work, but xscreensaver-demo won't be as
788 Changes since 3.18: * Fixed gcc dependencies in `bumps' and `ccurve'.
789 * New hack, `extrusion'.
790 * Some of the web sites that `webcollage' was using as
791 its sources changed formats; tweaked it to understand
793 * Added typeahead in the password dialog: if the screen
794 is locked, and you unlock it by typing a character,
795 that key will be automatically inserted in the
796 password dialog (unless it is Return, Enter, Space,
797 or a non-printing key like Shift.)
798 * Made `xmatrix' take a `-small' option, since some
799 folks with tiny screens prefer a smaller font.
800 Changes since 3.17: * New versions of `shadebobs', `lmorph', and `distort'.
801 * Added `ccurve', `blaster', and `bumps' hacks.
802 * Replaced `forest' hack with a rewritten version.
803 * Worked around a Xinerama server bug.
804 * Fixed a bug I introduced in 3.10 that caused some
805 hacks to print out superfluous warnings about not
806 having gotten enough colors.
807 * Made `sproingies' obey the `-delay' option.
808 * Fixed a portability bug in `shadebobs'.
809 * Made `webcollage' and `vidwhacker' use `xli' in
810 preference to `xv', if it is available.
811 * Added a new source of images to `webcollage'.
812 * If running under KDE, xscreensaver will add itself to
813 KDE's list of screensavers (via xscreensaver.kss.)
814 * Improved detection of GL libraries.
815 * Made the password dialog include the date and time.
816 Changes since 3.16: * New version of `webcollage' -- deals better with
817 corrupted images, and can use an http proxy.
818 * New hack, `xsublim' (run it in the background,
819 rather than adding it to the programs list.)
820 * The xscreensaver daemon was leaking a file descriptor
821 each time you edited your .xscreensaver file. Fixed.
822 Changes since 3.15: * New version of `shadebobs'.
823 * Improved image selection in `webcollage', and sped it
825 * Made configure find the right version of perl.
826 * Rewrote the CGI part of `webcollage'.
827 * `make clean' was deleting some things it shouldn't.
828 * Fixed a typo in the default programs list.
829 Changes since 3.14: * Added `webcollage' and `shadebobs' hacks.
830 * Added a `-stdout' arg to `vidwhacker' so that it can
831 be used in a pipeline.
832 * Made `petri' use less memory.
833 Changes since 3.13: * Various improvements to the Gtk port.
834 * Turned off PAM by default on Solaris, since PAM seems
835 generally to be misconfigured out-of-the-box.
836 * Made the `--without-gtk' configure option work.
837 * Made configure check the Gtk version number, since it
839 * Fixed a bug in the code that attempted to prevent
840 changes of screen resolution while the screen is
842 * Fixed a race condition in `xscreensaver-demo' that
843 could cause an X error at startup.
844 * Added `-transparent' option to `deluxe'.
845 * Added `petri' hack.
846 Changes since 3.12: * Ported `xscreensaver-demo' to Gtk.
847 * Made it possible to build Motif, Gtk, and Athena
848 versions of `xscreensaver-demo' in the same directory
849 without reconfiguring.
850 * Made `xscreensaver-demo' chase symlinks before writing
851 the .xscreensaver file, so that if .xscreensaver is
852 itself a symlink, the underlying file will be replaced
854 * Some Makefile and configure tweaks for Solaris and
856 * Made it possible to set the fire color in `xflame'.
857 * Made transparency work in TrueColor (for `goop' and
859 * Fixed a multi-head bug introduced by the virtual
861 Changes since 3.11: * Made it so that you can't scroll the screen while the
862 lock dialog is up (with XFree86 virtual viewports.)
863 * Fixed a bug in `flag' that caused bob's chin to get cut
864 off after a few iterations.
865 Changes since 3.10: * Made `xjack' be black-on-white-ish, so that it looks
866 less like a computer screen and more like the
867 typewritten paper it's supposed to be.
868 * New version of `pulsar'.
869 * Fixed Solaris compilation problem in `phosphor'.
870 * Made xscreensaver notice XFree86's virtual root window
871 hack, so that if the X server's root window is larger
872 than the monitor's displayable resolution, the screen
873 saver will limit itself to the area that actually
874 appears on the screen.
875 * Made the xscreensaver daemon do a better job of
876 picking the visual class that should be used for GL
877 programs. Less user intervention should be needed
878 now: you can use the logical visual name `GL' instead
879 of having to figure out by hand which one to use.
880 * Oops, the visual was defaulting to "best" instead of
881 "default", because the .xscreensaver file was not being
882 loaded quite early enough.
883 * Made configure figure out how to build icmp ping
884 support into the `sonar' hack automatically.
885 * Made warnings about not being able to read shadow
886 passwords not be printed if compiled with PAM support.
887 * Improved PAM startup diagnostics.
888 * Worked around the Solaris PAM bug that was causing
889 crashes there, so now PAM is turned on by default.
890 * Made configure detect the number of arguments that
891 pam_strerror() takes, since on Linux, this apparently
892 changed between 2.0 and 2.2, sigh.
893 * Made the /proc/interrupts kludge look for "PS/2 Mouse"
894 as well as "keyboard".
895 * Made xscreensaver notice when there has been a sudden
896 large jump in wall-clock time, and if so, lock right
897 away, instead of waiting for "lockTimeout" to expire
898 first. (Laptops need this for safer recovery from
900 * Added `-throttle' option to `xscreensaver-command'.
901 Changes since 3.09: * Added `phosphor', `xmatrix', and `pulsar' hacks.
902 * Fixed a bug in the color allocator that sometimes
903 caused `starfish' to fall back to monochrome.
904 * Reduced the amount of code that runs before root
905 privileges are disavowed: "normal" and "shadow"
906 passwords now do some initialization as root, but the
907 PAM and Kerberos authorization schemes will be
908 initialized while running as "nobody". Supposedly
909 this closes a potential security hole when using
911 * Added some more sanity checking to configure.
912 Changes since 3.08: * Added `compass', `squiral', `xflame', `wander',
913 `spotlight', and `critical' hacks.
914 * Added some new modes to `decayscreen'.
915 * Made `deluxe' work in monochrome.
916 * Generalized usage of the Double-Buffer server extension
917 in several hacks (`compass', `deluxe', `interference',
918 `kumppa', and `moire2'.)
919 * Fixed another visual-depth problem in `rd-bomb'.
920 * The screen saver will now defer blanking if neither
921 the keyboard nor the mouse could be grabbed. Instead,
922 it will just try again in a few minutes. This fixes
923 a bad interaction between xscreensaver and programs
924 like VMware that hold the mouse and keyboard grabbed
926 * Added a new erase mode (expanding spiral.)
927 Changes since 3.07: * Fixed some bugs in my port of `t3d'.
928 * Added `penetrate' and `deluxe' hacks.
929 * When linking against Motif 2.x, also link against XPM.
930 * Added support for using /proc/interrupts for idle
931 detection on Linux. Now xscreensaver shouldn't kick
932 in when the user is active on a non-X virtual console.
933 * Upgraded to autoconf 2.13.
934 Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
935 in properly; check for _Xsetlocale in -lXintl.)
936 * Portability fixes for sonar.c.
937 * Fixed a compilation problem when you have GL but don't
939 * Made configure notice when MesaGL requires -lpthread.
940 * Made `flame' ignore SIGFPE (not sure if this is the
941 right fix; it seems only to be needed on FreeBSD.)
942 * Kludged `rd-bomb' work on visuals that are of depth 24
943 but that *do not* support pixmaps of depth 32.
944 * Fixed `halo' to work properly in TrueColor.
945 * Changed `xscreensaver.spec' to install the hacks in
946 /usr/X11R6/lib/xscreensaver/ by default, since that's
947 where recent Red Hat distributions put them.
949 * Updated versions of `crystal', `hopalong', and `flow'
951 * Imported `demon' and `loop' modes from xlockmore.
952 Changes since 3.05: * Oops, the "default-n" visual descriptor was broken;
953 it was always installing a colormap if the
954 `installColormap' preference was set, meaning that
955 `xearth', `xv' and friends were using the wrong
956 colors on 8-bit systems.
957 * Turned off HAVE_PING in `sonar', since it compiles
958 on some Linux systems, but not others of similar
960 Changes since 3.04: * Fixed an off-by-1 in `distort'.
961 * Added `sonar' hack.
962 * New version of `glplanet' (with stars.)
963 * Made all hacks exit when you type `q' or `ESC' at them,
964 and made them obey the WM_DELETE_WINDOW ClientMessage.
965 * Fixed a nonfatal buffer overrun in lament (note:
966 lament still doesn't work with MesaGL 3.0: it dies in
967 lambda_textured_triangle1(), which is Mesa's bug, not
969 Changes since 3.03: * Added an `xscreensaver.spec' file, to make it easier
970 for other folks to generate RPMs.
971 * Made the password code work on HPUX in the situation
972 where: ``enhanced security'' is available; but not
973 used; but the user typed a password more than 8
974 characters long anyway. FTSOHPUX.
975 Changes since 3.02: * Made locking work when passwd aging is enabled.
976 * Added support for PAM (Pluggable Authentication
977 Modules.) It is still turned off by default, though,
978 since it doesn't seem to work on Solaris 2.6, and has
979 been behaving erratically on Red Hat 5.1.
980 * Made each possible authentication method be tried in
981 turn until one succeeds; this means that Kerberos is
982 being used, we will first check Kerberos, and if that
983 fails, will then consult the local password file.
985 * Save and restore the bits under the passwd dialog,
986 to avoid leaving a black rectangle behind when
987 unlocking is cancelled.
988 Changes since 3.01: * Not everyone has sys/select.h, sigh...
989 Changes since 3.00: * Some fixes to `reflect'.
991 * Made it log unsuccessful attempts to unlock the screen
993 * Fixed a bug where `xscreensaver-demo' could be seeing
994 a different programs list than `xscreensaver' did.
995 Changes since 2.34: * The xscreensaver daemon no longer links against Motif
996 or Athena: demo-mode and the preferences panel are no
997 longer built in to the daemon, but are now handled by
998 an external program, `xscreensaver-demo'.
999 (I decided that this, along with the recent addition
1000 of the `.xscreensaver' config file, justified bumping
1001 the version number to 3.00, since this is a fairly
1002 major architectural change.)
1003 * Lines in the `*programs' resource may now begin with
1004 the character "-", meaning "don't run this hack."
1005 In this way, it's possible to disable a hack without
1006 throwing away the information about it (making it
1007 easier to change your mind later.) Eventually the
1008 preferences/demo mode GUI should represent this as a
1009 checkbox or something.
1010 * Fixed a short race condition where it was possible for
1011 xscreensaver to die with a BadWindow error if it was
1012 blanking the screen just as another window was being
1014 * Made it possible to disable specific modes in `bsod'.
1015 Changes since 2.33: * Fixed a bug that was making `pipes' generate way too
1016 many valves. Made the viewpoint in `pipes' be selected
1017 randomly instead of always being -10 degrees.
1018 * Fixed a bug in the XSHM code, in the case where the
1019 server supports the XSHM extension but is not the same
1020 machine as the client.
1021 * Made `rd-bomb' default to taking up the whole screen.
1022 * Made it not try to do fading/unfading if no PseudoColor
1024 * Initial attempt at supporting VT-locking (doesn't work
1026 * Eliminated the `captureStdout' resource; now
1027 `captureStderr' controls both streams.
1028 * Added `-capture-stderr' and `-no-capture-stderr'
1029 command-line arguments.
1030 * Added `glplanet' hack.
1031 * When a hack is selected with `xscreensaver-command
1032 -select', that hack will be used until further notice
1033 (until the saver turns off, or another activation
1035 Changes since 2.32: * Made `xscreensaver-command' print error messages:
1036 the xscreensaver daemon now responds to ClientMessage
1037 events by writing a response message on a window
1038 property, instead of just writing to its stderr.
1039 * Made the ~/.xscreensaver file be automatically reloaded
1040 when the file date changes.
1041 * The password dialog and splash screen no longer depend
1042 on Motif or Athena. This should clear up a number of
1043 focus problems, and is the first step on the path
1044 toward moving all of the Motif/Athena/whatever code
1045 out of the xscreensaver daemon, and into external
1047 * Don't complain about LessTif 0.86 any more, since the
1048 new password dialog makes that problem go away.
1049 * Configure tweaks for Irix 6.5, SunOS 5.something.
1050 * New `-reflect' option to `distort'.
1051 Changes since 2.31: * Added reading and writing of a ~/.xscreensaver file,
1052 so that the Preferences panel can save its settings.
1053 * New version of `rubik'.
1054 * Added `-select N' argument to `xscreensaver-command'.
1055 * Oops, left out some of the `bubbles3d' files...
1056 Changes since 2.30: * The cursor was invisible in the password dialog. Fixed.
1057 * Made configure warn against MesaGL 2.6.
1058 * Fixed X error at startup when using non-default visual.
1059 * New version of `crystal', `ant', and `atlantis' from
1061 * New hack, `bubble3d'.
1062 * Added some new modes to `bsod'.
1063 Changes since 2.29: * Changed the order in which -lSM and -lICE are linked
1064 to be after Motif instead of before (Lesstif on Irix
1066 Changes since 2.28: * Work around a bash bug in configure.
1067 * Tweaked HPUX paths again. FTSOHPUX.
1068 * Made configure recommend against LessTif 0.86, due
1069 to a bug in that version that causes a security hole
1070 in the screen locking code. LessTif 0.87 will fix it.
1071 * Made all of the `--with' options to `configure' accept
1072 a directory option as well (so that --with-motif=/FOO
1073 will add -I/FOO/include -L/FOO/lib). I believe this is
1074 the Configure Party Line of how do to such things.
1075 * Fixed a bug where the mouse was left un-grabbed
1076 after the first time the graphics hack was changed
1077 (simplified all of the mouse-grabbing logic.)
1078 * Maybe possibly perhaps made `vidwhacker' really not
1079 leave stray xv windows around. This time for sure.
1080 * Added a new erase mode (random dots fizzling out.)
1081 * Added `-prefs' argument to `xscreensaver-command',
1082 that brings up the Preferences dialog directly (it
1083 seems that nobody ever noticed the `Preferences' button
1084 on the Demo Mode dialog, maybe this will help.)
1085 * Added a splash screen. Turn it off with *splash:false.
1086 Changes since 2.27: * Better macsbug text in `bsod'.
1087 * New version of `distort' with many new modes.
1088 * Plugged a leak in `coral'.
1089 * Tweaked configure for HPUX.
1090 * Removed some compiler warnings.
1091 * More consistent usage of stderr versus stdout.
1092 * More diagnostics should an X error occur.
1093 * Fixed a possible crash in SGI-specific unfading code.
1094 Changes since 2.26: * Improved version of `distort'.
1095 * Made `lament' compile against OpenGL 1.0 (though it
1096 still requires 1.1 to work properly.)
1097 * Updated my email address and home page.
1098 Changes since 2.24: * Improved motion in `rd-bomb'.
1099 * Added XSHM (shared memory extension) support to the
1100 `distort', `interference', `moire', `rd-bomb', and
1101 `swirl' hacks, which speeds them up a bit.
1102 * Added `lament' hack.
1103 Changes since 2.23: * Tweaked the order of the -L options again.
1104 * Cleaned up configure's `--help' message.
1105 * Added `kumppa' hack.
1106 * Smarter maze-solving algorithm in `maze'.
1107 * Took `xlyap' out of the default list of hacks, since
1108 it's just incredibly buggy (and slow.) Maybe someday
1109 someone will fix it...
1110 * Added `distort' hack, but didn't add it to the default
1111 list (yet) because it's still too slow.
1112 * Made the Athena demo dialog look more like the Motif
1113 version; it has a text-entry field now, too.
1114 * Made the Athena password dialog echo asterisks, like
1115 Motif does, instead of using a flyspeck font.
1116 * Some random configure tweaks.
1117 * Added a `timestamp' resource that makes the `-verbose'
1118 messages include the time at which they were printed.
1119 Changes since 2.22: * The fix for SGI's ``scheme'' nonsense broke things, and
1120 let the user's "*background" resource show through.
1121 Fixed it in a different way.
1122 Changes since 2.21: * Added support for the DPMS server extension (Display
1123 Power Management System.)
1124 * Made configure advertize the `--enable-subdir' option a
1125 little more, since that seemed to cause some people
1126 stress. Also, made that directory be built into the
1127 xscreensaver executable, as a hardcoded prefix to
1128 $PATH. (Might help, shouldn't hurt.)
1129 * Made configure prefer the two-arg gettimeofday to the
1130 one-arg version, since AIX doesn't have any prototypes.
1131 * Made it work with Xaw3d (the 3D Athena library.)
1132 * Made `make install' create directories as necessary.
1133 * New version of lmorph from Sverre.
1134 * Added `crystal' and `discreet' hacks from xlockmore.
1135 * Added a new mode to `bsod'.
1136 Changes since 2.20: * Made `xscreensaver-command -time' use different words.
1137 (It now describes the two states as "screen blanked
1138 since..." and "screen non-blanked since..." instead of
1139 "active since..." and "inactive since..." which a lot
1140 of people interpreted as meaning the opposite of what
1142 * Improved some error messages, in the hopes of making
1143 the distinction between the xscreensaver and
1144 xscreensaver-command programs more obvious.
1145 * Rewrote (and reorganized) parts of the xscreensaver and
1146 xscreensaver-command manual pages.
1147 * Renamed xscreensaver's `-lock' command-line option to
1148 be `-lock-mode', to avoid confusion with the `-lock'
1149 option to xscreensaver-command, which does a totally
1151 * Removed xscreensaver's `-demo' command-line option for
1152 a similar reason; use `xscreensaver-command -demo'
1154 * Disabled SGI's ``scheme'' nonsense in a better way than
1155 fully-qualifying the background colors in every single
1157 * Fixed some other minor cosmetic problems when *sgiMode
1159 * Fixed an X error in `bsod -root' (how ironic...)
1160 Changes since 2.19: * Fixed a bug that caused the mouse to sometimes not be
1161 grabbed properly (meaning the window manager menu could
1162 pop up over the demo-mode display.)
1163 * Fixed a bug that made the stderr output sometimes get
1165 * Fixed a bug that made the demo-mode scrollbar move too
1167 * Protected against a possible buffer overflow.
1168 * Made `vidwhacker' not leave stray xv windows around.
1169 * New version of `ant' so that Bagley doesn't calve.
1170 * Make configure on AIX get XShm from the right library.
1171 Changes since 2.18: * One file was missing from the tar file. Fixed.
1172 Changes since 2.17: * Oops, atlantis wasn't being built by default. Fixed.
1173 * Added `epicycle' hack.
1174 * Added `interference' hack.
1175 * Added `truchet' hack.
1176 * Added `bsod' hack.
1177 * Added some new modes to `vidwhacker'.
1178 Changes since 2.16: * Added a -window-id argument to most hacks, so that they
1179 can draw on arbitrary externally-provided windows.
1180 * Synched with xlockmore 4.11a01.
1181 * Added `flow' hack.
1182 * Added `atlantis' GL hack.
1183 * Renamed `puzzle' hack to `jigsaw', since xlock already
1184 had a different mode called `puzzle'.
1185 * Made it self-configure properly when Motif 2.1.0 is
1186 being used (requires -lXp now, sigh...)
1187 Changes since 2.15: * Made `flag' able to do XPM images.
1188 * New look for the xscreensaver logo (`xroger').
1189 * Fixed compilation error on Suns with adjunct passwords.
1190 * Got multi-architecture builds working again.
1191 * Some configure tweaks for building on HPUX and Solaris.
1192 * Fixed bug in decayscreen.
1193 * Fixed typo in passwd.c.
1194 * Made `cynosure' not die when colormap is full.
1195 Changes since 2.14: * Added `cynosure' hack.

1197 * Tweaked `erase.c' some more.
1198 * Made unfading a bit smoother.
1199 * Added `vidwhacker' hack (not installed by default.)
1200 * Added `stairs' hack.
1201 * Split `escher' into `cage' and `moebius', as per
1203 * Changed subprocess handling to use sigaction() instead
1204 of signal() if it's available (this is necessary for
1205 SCO but should work fine on other systems too.)
1206 * Various other tweaks.
1207 Changes since 2.13: * Better fix for the Motif drag-and-die lossage.
1208 * Put in some kludges to work around a LessTif bug.
1209 * XScreenSaver is known to work with LessTif 0.82 now.
1210 * Made fading work on high-end SGI video hardware.
1211 * Fixed another SGI-specific bug in screen grabbing;
1212 will the madness never cease?
1213 * Fixed another crash in `xlyap'.
1214 Changes since 2.12: * Made `decayscreen' do directions other than down.
1215 * Improved `puzzle'.
1216 * Fixed a crash in `xlyap'.
1217 * Added CDE info to the man page, removed `cde.txt'.
1218 * Configure tweaks for Zippy.
1219 * Turned off the signal handling in `bubbles' because
1220 it was sometimes failing to die.
1221 * Added `hacks/xscreensaver-sgigl.c' to make it possible
1222 to run SGI's ElectroPaint hack (/usr/demos/bin/ep)
1223 with xscreensaver. Finally!
1224 * Fixed a buffer overrun in the locking code that some
1225 wily, malicious cracker must have slipped in.
1226 * Disabled Motif drag-and-drool in the dialog box
1227 buttons, since it's broken in some old versions of
1229 Changes since 2.11: * Added `README.debugging'.
1230 * Added `puzzle' hack.
1231 * Added `xlyap' hack.
1232 * Added `default-n' as a visual name, so that one can
1233 have -install on by default, but turn it off for
1234 certain poorly-behaved hacks (like xv.)
1235 * Added support for grabbing frames of external video
1236 (on SGI) to the screen-grabbing hacks (decayscreen,
1237 slidescreen, slip, blitspin, and puzzle.)
1238 * Improved look of tiles in `slidescreen'; fixed its
1239 color allocation problem.
1240 Changes since 2.10: * Tweaked `blitspin', added it to the default list.
1241 * Added `lissie', `mountain', `triangle', `worm',
1242 `rotor', and `ant' from xlockmore.
1243 * Updated `sierpinski', `galaxy', and `lisa'.
1244 * Thickened the lines in `braid' and `lmorph'.
1245 * Updated VMS makefiles.
1246 * Renamed `fract' to `vines'.
1247 * Added `xjack' hack.
1248 * Made a few more hacks use erase.c, and added a few
1250 * Fixed compilation problem with Sun's version of OpenGL.
1251 * Added ability to use sigaction() instead of signal()
1252 to work around a SCO kernel bug.
1253 Changes since 2.09: * Fixed colormap bugs in `rd-bomb'; sped up `coral'.
1254 * Configure tweaks for *BSD.
1255 Changes since 2.07: * New hacks `rd-bomb' and `coral'.
1256 * New version of `maze' with some new algorithms.

1268 configure to detect the extra-random -Xss library.
1269 Changes since 2.03: * HP configure tweaks. Detect and warn about LessTif.
1270 * Fixed low-color behavior of `goop', `pyro', `starfish',
1271 `greynetic', `flame', `halo', and `moire'.
1272 Changes since 2.02: * Fixed flicker in `pipes'. Fixed 3d in `bouboule'.
1273 * Added `munch' hack.
1274 * Added basic dependencies to the Makefile.in files.
1275 Changes since 2.01: * Fixes for compiling with the MIT saver extension.
1276 * Made the yow/fortune program be a configure option.
1277 * Various configure tweaks.
1278 Changes since 2.00: * Added `goop' and `starfish' hacks.
1279 * Added colomap cycling to `halo'.
1280 * Made `attraction' use the new colormap allocator.
1281 * Added better $PATH diagnostics.
1282 * There was a bug in frand! Color selection should be
1284 Changes since 1.34: * Converted to use `configure' instead of `imake'.
1285 * ANSI C is now required.
1286 * Added Kerberos locking support, from Nat Lanza.
1287 * Made the stderr text use overlay planes, if possible.
1288 * Reworked the xlockmore compatibility stuff again.
1289 * Added `gears', `superquadrics', `escher', `pipes',
1290 and `sproingies' hacks (depend on OpenGL.)
1291 Changes since 1.33: * Fixed some bugs, made fading be a little smoother.
1292 Changes since 1.32: * Made it work with multi-headed displays.
1293 * Generalized sub-process management (Unix sucks!)
1294 * Added interactive mouse frobbing to Julia.
1295 * Added (untested) support for HPUX shadow passwords.
1296 * Made normal non-shadow passwords be checked if the
1297 shadow passwords aren't accessible for some reason.
1298 Changes since 1.31: * Removed *colorPrograms and *monoPrograms resources:
1299 made it possible to specify the desired visual on a
1301 * Cleaned up / restructured the driver: no more globals.
1302 * Made the Motif and Athena dialogs share more code.
1303 * Probably fixed some Athena colormap-installation bugs.
1304 * Fixed screen grabbing (cmap) on SGI 12-bit PseudoColor.
1305 * Fixed divide-by-zero in bright random colormaps.
1306 * Added an improved version of xlock's `flag' hack.
1307 * Made unfading work better, and not flicker on SGIs.
1308 * Added `sphere', `forest', `lisa' hacks from xlockmore.
1309 * Added (untested) support for SunOS Adjunct passwords.
1310 Changes since 1.30: * Improved colors and colormap cycling of many hacks.
1311 * Cleaned up xlockmore compatibility layer.
1312 * Made `blitspin' able to grab an image off the screen.
1313 * Ported `swirl' and `bouboule' hacks from xlockmore.
1314 * Made the driver more careful about not leaving bits on
1315 the screen, or allowing other windows to raise
1316 themselves: it now re-blanks the screen every so often.
1317 * Added `-time' option to `xscreensaver-command'.
1318 * Improved SGI screen-grabbing some more: now it can grab
1319 TrueColor screens into PseudoColor windows and have the
1320 colors still come out semi-reasonably.
1321 Changes since 1.29: * Made `slidescreen' and `decayscreen' work better on
1322 SGIs when windows of different visuals are present, by
1323 using the XReadDisplay() extension to get a true 24-bit
1324 image out of the frame buffer.
1325 * Made `noseguy' be in color, if compiled with XPM.
1326 * Ported `braid', `drift', `fract', `galaxy', `grav',
1327 `ifs', `julia', `laser', `lightning', `penrose',
1328 `sierpinski', `slip', `spiral', and `strange' hacks
1330 * Merged `hopalong' hack with a more recent version.
1332 Changes since 1.27: * Added `deco', `moire', and `kaleidescope' hacks.
1333 * Merged in support for non-Motif locking and demo mode.
1334 * Made `blitspin' and `bubbles' work in TrueColor.
1335 * Fixed a stupid bug I introduced in `imsmap'.
1336 * Added `poly' and `gravity' options to `qix'.
1337 Changes since 1.26: * Added support for SGI SCREEN_SAVER extension.
1338 * Made `fade' and `unfade' work on 8-bit SGIs.
1339 * Made the dialog boxes more Motify.
1340 * Added `bubbles' hack.

1342 * Added viscosity and mouse-control to attraction.
1343 * Fixed possible bad color choices in qix and attraction.
1344 * Added ramp-mode to halo.
1345 * Added a new RNG, which is faster and more portable
1346 than using the RNG in libc.
1347 * Made locking work on SCO.
1348 * Various other minor tweaks that I don't remember.
1349 Changes since 1.24: * Made it capture the stdout/stderr of its subprocesses
1350 and present them on the screensaver window itself.
1351 * Made demo mode work correctly with non-default visuals
1352 and color maps, instead of always using the defaults.
1353 * Added -visual argument to all included screenhacks.
1354 * Support for the R6 MIT-SCREEN-SAVER server extension.
1355 * Made the demo mode list scroll properly.
1356 * Added `pedal' hack.
1357 Changes since 1.23: * Fixed some private-colormap oddities in slidescreen,
1358 decayscreen, and xroger. Fixed apparent conservation-
1359 of-mass problem in pyro; made the shrapnel round.
1360 Changes since 1.22: * Minor tweaks for IRIX5; fixed locking race condition.
1361 Changes since 1.21: * Minor tweaks for X11R6.
1362 * Fixes for non-default visuals.
1363 Changes since 1.20: * Fixed bug in color blitspin; added default image.
1364 * Added diagnostics to noseguy. Fixed off-by-one
1365 error in flame. Added some missing casts.

1375 Changes since 1.15: * Portability fixes.
1376 Changes since 1.14: * Broke the driver up into more source files.
1377 * Moved the hacks into their own directory.
1378 * Made all `time' parameters accept the 00:00:00 syntax,
1379 so that even the parameters which are normally read as
1380 minutes can be specified in seconds.
1381 * Added colormap cycling to `imsmap'.
1382 * Made hyper work with K&R compilers.
1383 Changes since 1.13: * Added `orbit' option to `attraction' hack.
1384 * Added `lock-timeout' option.

1389 Changes since 1.4: * Works when run from XDM before anyone logs in.
1391 * Can use `xv' as a slideshow without using up colormap
1392 entries while the screen is not blanked.
1393 * Fixed a BadDrawable error in non-XIdle mode.
1394 * Added `blitspin' and `imsmap'.
1395 Changes since 1.0: * Current list of included hacks is now: qix, helix,
1396 rorschach, attraction, greynetic, rocks, pyro,
1397 hopalong, and noseguy.
