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

137 * When the password dialog has timed out or been
138 cancelled, don't pop it right back up a second time.
139 * Password timeouts/cancels don't count as
141 * Retired some of the older, less interesting savers:
142 say goodbye to `bubbles', `critical', `flag', `forest',
143 `glforestfire', `lmorph', `laser', `lightning', `lisa',

168 * New hack, `skytentacles'.
169 * New version of `gleidescope'.

195 fallout from the recent PAM changes...)
196 * New hacks, `moebiusgears', `abstractile', and
198 * Rewrote `gears' to use better (involute) gear models,
199 and to be more random.

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

222 * `xflame' and `flag' ignore bitmap option on MacOS.
223 * `speedmine' prefs work on MacOS.
224 * Better explosions in `boxed'.

226 * More options in `flipflop'.
227 * Minor updates to `topblock'.
228 * Various other minor fixes.
229 Changes since 4.24: * Ported to MacOS X! (10.4.0 or newer)
230 * API change: instead of providing a single screenhack()
231 function that does not return, screen savers using the
232 screenhack.h framework must now provide "init" and
233 "draw one frame" functions instead. All bundled savers
234 have been updated; third-party patches will need work.
235 * All image-loading happens asynchronously.
236 * xscreensaver-getimage-file caches the contents of the
237 image directory for a few hours, so consecutive runs
238 won't have to re-list the whole directory tree.
239 * New hacks, `topblock' and `glschool'.
240 * Removed `xteevee' (superceded by `xanalogtv').
241 * Added variable-sized puzzle pieces to `jigsaw'.
242 * Changes to the defaults and command-line options of
243 many hacks to make the .xml files more consistent.
244 * Reap zombies in `glslideshow' and `carousel'.

246 * `xmatrix -mode pipe' displays the text of a subprocess.
247 * `endgame' has higher resolution chess-piece models.
248 * `webcollage' takes a -directory option to get images
249 from a local directory.
250 * The RPM spec file no longer auto-restarts xscreensaver
251 when a new version is installed. Restart it manually.

253 * Backed out a DPMS-related patch that cause desktop
254 flickering with some X servers.
255 * Fixed startup crash in getgroups() when running setuid.
256 * Default to not displaying stderr on the saver window.

259 * Minor fixes to various XML config files and man pages.
260 Changes since 4.22: * New hacks, `glhanoi', `cube21', `timetunnel',
261 `juggler3d', and `celtic'.
262 * New versions of `tangram', `webcollage', `hypertorus',
263 `polytopes', and `ripples'.
264 * `sonar' is now quiet about unresolvable hosts.
265 * Minor corrections to BASIC code in `apple2'.
266 * xscreensaver-demo now provides an RPM clue when none
267 of the hacks seem to be installed.
268 * Don't install `ant' by default, since there is some
269 Java tool of that name, which was causing confusion.
270 And also it's boring.
271 * Made screen grabbing work again on MacOS 10.4.2.
272 * No longer prints bogus warnings about ClientMessages
273 intended for the window manager.
274 * Ignore unprintable characters in passwd entry field.

277 * `xscreensaver-command -watch' and `-time' now work
279 Changes since 4.21: * Fixed a bug in the new mouse-motion code that caused
280 the screen to never blank on multi-head non-Xinerama
282 * New hacks, `interaggregate', `antmaze', `tangram',
284 * Minor tweaks to `fiberlamp', `ifs', `slidescreen',
285 `zoom', `sonar', `fireworkx', `whirlwindwarp',
286 `bubble3d', and `rd-bomb'.
287 * Added motion blur to `blinkbox'.
288 * `bsod' now includes Longhorn's "RSOD", and OS/2.
289 * Fixed `-wireframe' usage in most hacks and man pages.
290 Changes since 4.20: * New hack: `fliptext'.
291 * Changed default configure installation directories:
292 /usr/bin/ for xscreensaver, etc.;
293 /usr/libexec/xscreensaver/ for hacks;
294 /usr/share/xscreensaver/config/ for xml files.
295 * All the text-manipulating screen savers can have their
296 text source configured via `xscreensaver-demo' now.
297 * xscreensaver.spec now builds three RPMs:
298 base (no hacks); extras (2d hacks); and gl-extras.
299 * Added `-program' and `-front' option to `gltext'.
300 * Added `-shells' to `molecule'.
301 * Fixed text-alpha glitch in `carousel'.
302 * New `pacman': the ghosts can be killed now.
303 * Fixed a bug in screen-grabbing GL hacks where images
304 would be tiled instead of scaled on machines that
305 can't do large textures.
306 * `webcollage' can hit Flickr now.
307 * New (rewritten) implementation of `ifs'.
308 * The unlock dialog can be made to have a "New Login"
309 button that will run `gdmflexiserver'. Experimental!
310 * Fixed non-ASCII display bug in `starwars'.
311 * Configure finds a default for imageDirectory.
312 * "xscreensaver-command -lock" now works even if
313 in "screensaver disabled" mode.
314 * If a bad password is typed while CapsLock is on, the
315 unlock dialog says "CapsLock?" instead of "Sorry".
316 * Mouse motion only counts as activity if the mouse moved
317 more than 10 pixels (so the screen won't unblank every
318 time you bump your desk.)
319 * New mode option "random-same": if you have multiple
320 monitors, this will run the *same* randomly chosen
321 hack on each screen, instead of different ones on each.
322 Changes since 4.19: * New hacks, `fiberlamp', `boing', `boxfit', and
324 * Rewrote `glslideshow' again: should be faster now.
325 * Sped up loading of images in GL programs.
326 * `starwars' uses texture-mapped fonts now.

339 `galaxy', and `webcollage'.
340 * Removed support for GTK 1.x (everyone uses 2.x now.)
341 Changes since 4.17: * Oops, pay no attention to the man behind the curtain.
342 Changes since 4.16: * New hacks, `anemotaxis' and `memscroller'.
343 * Fixed a bad bug that caused `vidwhacker' to never die.
344 * Fixed normals and lighting in `polyhedra'.
345 * Don't reuse the window when changing hacks (to work
346 around bugs in some GL implementations.)
347 * Made `xscreensaver-getimage-file' skip thumbnail-sized
349 * Fixed endian problem in `barcode' on non-x86.
350 * Updates to `webcollage', `apple2', `fuzzyflakes',
351 `atunnel', and `pacman'.
352 * Timing tweaks to `bubble3d', `bouncingcow', `engine',
353 `gltext', `lavalite', `molecule', `spotlight',
354 `sballs', `boxed', `blinkbox', and `circuit'.
355 * Configure updates for Fedora core 2 / xorg 6.7.0.
356 * Compile without warnings under gcc 3.3.3.
357 * I give up: don't blank or lock the screen if we can't
358 get a keyboard grab. In that case, both choices are
360 Changes since 4.15: * New hacks, `polyhedra', `fuzzyflakes', `antinspect',
362 * Minor updates to `webcollage', `bsod', `endgame',
363 `antspotlight', `xmatrix', and `glmatrix'.
364 * Added support for the RANDR (Resize and Rotate)
365 extension to detect when the size of the desktop has
366 been changed while xscreensaver is already running.
367 * Possibly-futile attempt to work around "rdesktop"
369 * Made `xscreensaver-getimage -file' still work even if
370 imageDirectory is unset.
371 * Convert Latin1 to ASCII in `starwars' and `phosphor'
372 (since the GLUT font only has ASCII glyphs.)

374 * Added "GetViewPortIsFullOfLies" preference to work
375 around longstanding XFree86 bug #421.
376 * Made `sonar' subnet pinging work properly on bigendian
377 machines (e.g., PPC.)
378 Changes since 4.14: * New hacks, `wormhole', `mismunch', `noof', and
380 * `phosphor' and `apple2' include vt100 emulators now:
381 this means you can do "phosphor -program top", or
382 can use either program as an xterm replacement:
383 "apple2 -text -fast -program 'xemacs -nw'".
384 * `analogtv' (and related) fill the screen better.
385 * The '-gradient' option works in `atlantis' now.

393 `gleidescope', `mirrorblob', and `blinkbox'.
394 * New version of `glsnake' (with many more models.)
395 * Another Windows crash in `bsod'; also HVX/GCOS6/TPS6.
396 * New version of `endgame'.
397 * Screen grabbing works on MacOS X.
398 * Various minor fixes.
399 Changes since 4.12: * On Xinerama systems, xscreensaver now runs one hack on
400 each monitor (just like in "real" multi-head mode)
401 instead of running one hack stretching across all the
402 screens. Note that for this to work with any 3rd party
403 screensavers, they must update their "vroot.h" file.
404 * `webcollage' and `vidwhacker' display images using
405 `xscreensaver-getimage' now.

419 wimpier video cards now.
420 * Various portability tweaks.
421 Changes since 4.09: * New hacks, `cloudlife' and `klein'.
422 * Added Apple ][+, HPUX, and OS/390 sessions to `bsod'.
423 * Added some Matrix Reloaded text to `xmatrix'.
424 * Updates to `webcollage', `eruption', `jigglypuff',
425 `metaballs', and `endgame'.
426 * Completely ignore the `memoryLimit' setting now,
427 since it was still causing people GL grief.
428 * Various minor fixes.
429 Changes since 4.08: * New hacks, `flyingtoasters', `bouncingcow',
430 `jigglypuff', and `glslideshow'.
431 * More models in `engine'.
432 * Rewrote `xscreensaver-getimage' to remove reliance on
433 external image loaders (xv, chbg, xloadimage, etc.)
434 and to reduce flicker when loading files.
435 * Made `gflux' and `flipscreen3d' be mouse-spinnable.
436 Changes since 4.07: * New hacks, `atunnels' and `piecewise'.
437 * Physics improvement in `fluidballs'.
438 * Various fixes for XDarwin systems (X11 on MacOS X.)

443 `popsquares', and `barcode'.
444 * Minor updates to `maze' for high density mazes.
445 * Added double buffering to `fluidballs' and `whirlygig'.
446 * Bug fixes for running xscreensaver to a remote XFree86
447 display (which nobody would ever do...)
448 * Updated `webcollage' (faster Alta Vista searching.)
449 * Updated `glplanet' so the sun sets in the west.
450 * Updated `sproingies' with smooth, unsegmented surfaces.
451 * Fixed Perl version-sensitivity in
452 `xscreensaver-getimage-file'.
453 * Fixed GTK2 scrolling bug in `xscreensaver-demo'.
454 Changes since 4.05: * New hack, `glblur' (disabled by default, since it
455 requires fast OpenGL texture support.)
456 * New hack, `halftone'.
457 * Updates to `endgame', `queens', `bumps', `glplanet',
458 `engine', and `circuit'.
459 * New version of `menger' that uses far fewer polygons.
460 * Fixed minor bug in `critical' that could cause some
461 bogus X servers to crash.
462 * Better labels in `molecule': the labels now appear to
463 be attached to the atoms, instead of floating in front
465 * Fixed bug that could rarely cause GL hacks to fail to
466 double-buffer (causing intermittent flickering.)
467 * Fixed a relative-URL-parsing bug in `webcollage'.
468 * Fixed a bug that (sometimes) caused the window manager
469 close box to kill `xscreensaver-demo' with a crash
470 instead of a graceful exit.
471 * Updated xscreensaver.pam to the Red Hat 7.3 way.
472 * More Gnome2-related configure crap.
473 * Updated to latest `config.guess' and `config.sub'.
474 * Fixed occasional core dump in `distort'.
475 * Added a Linux fsck failure and kernel panic to `bsod'.
476 * Added MacOS X kernel panic to `bsod'.
477 * Fixed a bug in `bsod' (all bsod bugs are ironic.)
478 * Fixed a bug that caused `xscreensaver-gl-helper' to
479 print a nonsense visual ID with some versions of
480 `printf': this could cause GL programs to display
481 incorrectly (e.g., flickery.)
482 Changes since 4.04: * More `configure' tweaks to try and get things working
483 on systems that both Gtk 1.x and 2.x installed.
484 * New hack, `endgame'.
485 * Minor updates to `gltext'.
486 Changes since 4.03: * Support for GTK 2.x / GNOME 2.x.
487 * The `configure' script will now use `pkg-config' if
488 you have it, in preference to `gtk-config', etc.

490 * Minor updates to `spheremonics', `gltext', `xmatrix'.
491 * You can use the mouse to manually spin most of the GL
492 hacks now (when they are displaying in a window.)
493 * Fixed a bug in `webcollage' (due to recent Alta Vista
494 url changes) that was causing it to try and load
495 incorrect image URLs.
496 * Made `xscreensaver-getimage' use gdk_pixbuf if it is
497 available: this means that those hacks that load images
498 will no longer rely on "xv", "xloadimage", etc. This
499 will close a race condition that could sometimes cause
500 your desktop background to be changed; and also makes
501 it possible for those programs to operate on image
502 files when running in windowed mode.
503 * `webcollage' can now be used in conjunction with
504 `driftnet' to display images snooped from your local
505 ethernet instead of obtained from search engines.
506 * Added man pages for all the hacks that didn't have
508 Changes since 4.02: * New hack, `spheremonics'.
509 * Minor updates to `webcollage', `cage', `moebius',
510 `morph3d', `boxed', `circuit', and `helix'.
511 * `pulsar' and `extrusion' can now load texture JPEGs.
512 * `rubik' now does non-square cubes.
513 * `fluidballs' now does various sizes of balls.
514 * `menger' and `sierpinski3d' now also show polygon
516 * `molecule' displays real subscripts in the formulae.
517 * GTK internationalization/localization support.
518 * Better detection of the various versions of libxml.
519 * Upgraded to autoconf 2.53 (from 2.13.)
520 Changes since 4.01: * Plugged a few minor leaks in `xscreensaver' and
522 * New hacks, `cubenetic' and `fluidballs'.
524 * Fixed sphere projection error in `glplanet'; installed
525 a better image of earth.
526 * Added Win2K and MacOS 1 crashes to `bsod'.
527 * Put back previous (better) version of `forest' that
528 was accidentially downgraded in the last release.
529 * New version of `bumps'.
530 * Made FPS computation in GL hacks more efficient: it
531 will influence the results less, thus resulting in
532 higher (but more accurate) reported frame rates.
533 Changes since 4.00: * New hacks: `twang', `glsnake', `boxed', `sballs',
535 * New hacks `apollonian', `euler2d', `juggle',
536 `polyominoes' and `thornbird', from xlockmore.
537 * Merged recent xlockmore changes into `ant', `braid',
538 `demon', `discrete', `drift', `fadeplot', `forest',
539 `grav', `hopalong', `ifs', `laser', `lightning',
540 `lisa', `lissie', `loop', `mountain', `penrose',
541 `rotor', `sierpinski', `slip', `sphere', `spiral',
542 `strange', and `vines'.
543 * Fixed the `gltext' bug that sometimes caused
544 horizontal lines to vanish again. This time for sure.
545 * Sped up `webcollage' by adding a C helper program to
546 replace the PPM pipeline. It also pastes images
547 semi-transparently now.
548 * Added support for the gdk_pixbuf library: if this lib
549 is available, then `blitspin', `xflame', and `flag'
550 can load GIF, JPEG, and PNG images in addition to XPM
552 * Fixed a rare race condition where the desktop-grabbing
553 hacks could sometimes leave the screen wedged, if the
554 user moved the mouse exactly when they were grabbing
555 the screen image (it would un-wedge the next time the
556 saver timed out or was activated.)
557 * Fixed incorrect colors in the screen-grabbing GL hacks
558 (`gflux' and `flipscreen3d'.)
559 * Made SIGHUP restart the daemon process (though using
560 `xscreensaver-command -restart' is still the preferred
562 * Tweaks to `xspirograph'.
563 * Minor configure and portability tweaks.
564 Changes since 3.34: * Redesigned `xscreensaver-demo' GUI: it now includes
565 small-preview and per-hack configuration dialogs.
566 * Added three new modes of operation: `One Screen Saver',
567 `Blank Screen', and `Don't Blank' (in addition to the
568 historical `Random Screen Saver').
569 * Configure now defaults to installing the hacks in
570 <prefix>/lib/xscreensaver/ instead of <prefix>/bin/.
571 (Most distros already did it this way.)
572 * New GL hacks, `menger', `engine', `flipscreen3d'.
573 * Made `sierpinski3d' be more colorful.
574 * New versions of `xmatrix' and `nerverot'.
575 * Fixed a bug in `starwars' that made the font be drawn
576 with thin lines in -root mode.
577 * Fixed a bad colormap bug in `crystal' that could make
578 *subsequent* hacks malfunction!
579 * Made `gflux' able to grab screen images (`-mode grab').
580 * Updated `webcollage' for recent search engine changes.
581 * Removed most command-line options to `xscreensaver':
582 just edit the ~/.xscreensaver file instead.
583 * Improved behavior on multi-screen and Xinerama systems:
584 the mouse now stays on the screen where the user left
585 it, and the password and splash dialogs always appear
586 on the screen that has the mouse.
587 * Made the splash dialog use more Gtk-like colors;
588 made it have only two buttons, "Settings" and "Help".
589 * Made `sonar' understand `.ssh/known_hosts2' format
590 files, and be better about stripping out illegal
592 Changes since 3.33: * Turned `memoryLimit' off by default, sigh. Apparently
593 some versions of the GL libraries (appear to) allocate
594 hundreds of megs for every GL program, so `memoryLimit'
595 was causing GL programs to malfunction or crash on
597 * Improved fading on TrueColor XFree86 4.1.x systems.
598 * New GL hack, `circuit'.
599 * Added `fuzz' mode to `decayscreen'.
600 * New version of `whirlygig'.
601 * Added links to `xplanet' and `sphereEversion'.
602 * Fixed rare race condition that could make `sonar' hang.
603 * Fixed potential crash in `speedmine'.
604 * Made `xscreensaver-demo' not crash when imageDirectory
605 was set to a non-existent directory.
606 * Made `xscreensaver-getimage-video' invoke XawTV's
607 `streamer' program better.
608 * Made `phosphor' and `starwars' deal with CR, LF,
609 or CRLF line endings.
610 * Changes for Cygwin compilation environments.
611 * Made `sonar' compile on systems that can't ping.
612 * Configure changes for HPUX 10.20.
613 * Made PAM code work on Red Had 4.2 systems.
614 * Made `xscreensaver-command -deactivate' work when the
615 saver is not active: what that does is reset the idle
616 timer, as if keyboard input had been detected. This
617 was added for the benefit of people writing DVD-playing
618 software: they can now prevent the screensaver from
619 kicking in by sending a -deactivate message once a
620 minute while the movie is playing and not paused.
621 * Various minor portability tweaks.
622 Changes since 3.32: * New hacks, `speedmine' and `whirlygig'.
623 * Sped up `pyro', made the explosions look a bit better.
624 * Added better stars to `glplanet' and `starwars'.
625 * Many internal changes to `webcollage'.
626 * Some new options to `attraction'.
627 * Minor fix to `noseguy' to avoid un-erased pixels.
628 * Rewrote the screen-eraser effects so that they complete
629 in the same amount of time regardless of how slow
630 your X server is (some of them were glacial on servers
632 * Fixed a potential free memory reference that could
633 sometimes cause a crash at startup.
634 * Possibly fixed a problem that could cause the daemon
635 to crash with an X error. I was never able to
636 reproduce this problem, but I think I might have
637 figured out what caused it.
638 * Worked around a problem that caused PAM authentication
639 to fail on some Red Hat 7.x systems.
640 * Added a `memoryLimit' parameter that controls the
641 amount of memory a graphics hack may allocate: if they
642 try to allocate more than this, malloc() will fail
643 (and they will exit or (safely) crash, rather than
644 hogging memory.) Default is 50M.
645 * Made `gnome-help-browser' be the default way to display
646 man pages in `xscreensaver-demo', if running on a
648 Changes since 3.31: * The image-manipulating hacks (`slidescreen', etc.) can
649 now operate on randomly chosen image files from disk,
650 or on frames captured from the system's video input,
651 instead of (or in addition to) manipulating images of
653 * Rewrote `vidwhacker' to use the new image-grabbing
655 * Made fading work on TrueColor XFree86 4.x systems.
656 * Fixed a subtle rendering bug in `atlantis' (the fish
658 * Made `atlantis' have a texture simulating light
659 reflections from the surface of the ocean.
660 * Fixed up label placement in `molecule'.
661 * Better color bars in `xteevee'.
662 * Made `install-strip' not try to strip scripts.
663 Changes since 3.30: * Put in more sensible defaults for DPMS, and updated
664 the documentation to reflect the fact that all your
665 DPMS settings are now belong to xscreensaver.
666 * Fixed the `xscreensaver.spec' file so that `--force'
668 * New versions of `rotzoomer' and `nerverot'.
669 * Fixed an OSF/1 compilation problem in `molecule'.
670 Changes since 3.29: * New hacks, `molecule', `dangerball', and `rotzoomer'.
671 * New version of `gflux'.
672 * Made `gltext' able to display the current time.
673 * Fixed a floating-point-precision problem in `gltext'
674 that sometimes caused horizontal lines to vanish.
675 * Removed the `-window-id' option from the hacks:
676 it never worked right, and was unnecessary.
677 * Made the `starwars' hack use thicker lines, antialias
678 the text, and fade out at the far edge instead of just
680 * Fixed an SHM segment leak in `moire'.
681 Changes since 3.28: * Better rendering of the new logo.
682 * New hack, `gltext'.
683 * Added `-planetary' option to `gears', to draw a
684 different kind of gear system.
685 * Made motion and rotation be smoother in `gears',
686 `glplanet', `moebius', `rubik', and `sierpinski3d'.
687 * Improved coloration in `sierpinski3d'.
688 * Made the GL hacks react to window size changes.
689 * Made most of the GL hacks take a -fps option (like
690 `pulsar' did), so you can use them to benchmark your
692 * Fixed the previous fix to `sonar'.
693 * Minor fix to `nerverot'.
694 Made sonar able to ping hosts on DEC OSF1.
695 * Eliminated a bogus "didn't get enough colors" warning
696 in some of the hacks.
697 Changes since 3.27: * New logo for xscreensaver!
698 * New hacks, `starwars' and `stonerview'.
699 * Made the motion of the bouncing ball in `stairs' be a
701 * Made newly-added screenhacks be added to .xscreensaver
702 automatically: if there are hacks in the app-defaults
703 file that are not also in ~/.xscreensaver, they will
704 be added to the end of the list.
705 * Redid the `Screensaver Options' part of the control
706 panel; xscreensaver now lets you configure your DPMS
708 * Fixed some Makefile problems with non-GL builds.
709 * Fixed detection of MesaGL for version 3.3.
710 * Better workaround to Red Hat 7.0's broken gcc.
711 * Added Sparc Solaris kernel panic to `bsod'.
712 Changes since 3.26: * New hacks: `zoom' and `whirlwindwarp'.
713 * Fixed a free-memory-reference bug in `sonar'.
714 * Better error handling when there are no suitable GL
716 * Added diagnostic dialog when xscreensaver-demo is
717 unable to launch xscreensaver (e.g., when running as
719 * Fixed a bug that caused screenhack argument changes
720 to be ignored when xscreensaver-demo was running as
721 root (if "root" and "nobody" have different home
723 * Made the programs default to ":0" if $DISPLAY is unset.
724 * Made the `-verbose' output include information about
725 which server extensions were supported at compile time.
726 * Worked around Red Hat 7.0's broken gcc 2.96.
727 * Updated default delays on the GL hacks to look better
728 on machines with super-fast 3D hardware.
729 * Install `screensaver-properties-capplet' to work around
730 the usual egregious GNOME lossage.
731 Changes since 3.25: * Added "enabled" checkboxes in the list of hacks in
732 xscreensaver-demo (Gtk version only.)
733 * New hacks `hyperball', `xrayswarm', and `gflux'.
734 * New versions of `nerverot', `galaxy', and `hypercube'.
735 * Small fixes to `phosphor', `shadebobs', `xflame',
737 * Added external helper program `xscreensaver-gl-helper'
738 to figure out which X visual to use for OpenGL
740 * Configure updates for XFree86 4.0, and for BSD.
741 * Made it be more tolerant of bogus /etc/group files.
742 * When installing the PAM config file, first try to just
743 copy an existing "xdm" or "login" config file, so that
744 xscreensaver does authentication in the same way as the
746 Changes since 3.24: * New hack, `nerverot'.
747 * Added BSD kernel panic to `bsod'.
748 * New version of `shadebobs'.
749 * New version of `petri'.
750 * Updated `webcollage' to handle recent Altavista URL
751 format changes; made it search the AP photo gallery.
752 * Revamped command-line options of `sonar' and made it
753 properly handle subnets.
754 * The `bubbles' hack can now trickle up or down the
756 * The `xsublim' hack can now read its text from programs.
757 * Support for GLE version 3 in `extrusion'.
758 * Fixed compilation problems in `maze'.
759 * Fixed a rare crash in `flow'.
760 * Fixes for minor installation problems.
761 Changes since 3.23: * Added `-ignorant' option to `maze' hack.
762 * Updates to `critical', `bsod', `xflame', and `flow'.
763 * Added support for Kerberos 5 (via its Kerberos 4
764 compatibility layer.)
765 * Fixed a bad leak in `xteevee'.
766 * Updated `webcollage' to handle recent Altavista URL
768 * Removed xscreensaver-demo's `Ok' and `Cancel' buttons,
769 since they were confusing people: all changes are now
771 * Made xscreensaver-demo install itself into the Gnome
773 Changes since 3.22: * Fixed some misplaced text fields in the Motif version
774 of xscreensaver-demo; fixed a crash in the Gtk version
775 that would happen if the programs list was empty.
776 * Fixed a recently-introduced bug in `pulsar'.
777 * Made `sierpinski3d' use solid tetrahedrons instead of
779 * Added `-trace' option to `xmatrix'.
780 * Added new hacks `xteevee' and `xspirograph'.
781 Changes since 3.21: * Fixed some bugs in xscreensaver-demo.
782 * Rewrote the Motif version of xscreensaver-demo to
783 match the new Gtk version.
784 * The Athena toolkit is no longer supported.
785 Changes since 3.20: * Tweaked the xscreensaver-demo UI (Gtk only.)
786 * Fixed a few visual selection bugs. I think the proper
787 GL visual should be used with nVidia systems now.
788 * Made the Makefiles obey $install_prefix.
789 * Made the `xscreensaver.spec' file able to generate both
790 GL and non-GL packages simultaneously.
791 Changes since 3.19: * Added new hacks `ripples' and `sierpinski3d'.
792 * Made `xscreensaver-command -exit' be silent when no
793 screen saver was running (instead of complaining.)
794 * Made `webcollage' and `vidwhacker' use `xloadimage'
795 when available (in addition to `xli' and `xv'.)
796 * Improved memory usage in `petri' and gave it a hard
797 cap on how much memory it can allocate.
798 * Added `-watch' option to `xscreensaver-command'.
799 * Made `xscreensaver-demo' come up with the
800 most-recently-run hack selected by default.
801 * Rewrote the Gtk version of `xscreensaver-demo'.
802 It's a lot easier to use now.
803 * Extended the format of the programs list in the
804 .xscreensaver file, for the benefit of the new
805 capabilities of `xscreensaver-demo'.
806 NOTE: you might want to delete your ~/.xscreensaver
807 file and allow it to be re-created! The old one
808 should still work, but xscreensaver-demo won't be as
810 Changes since 3.18: * Fixed gcc dependencies in `bumps' and `ccurve'.
811 * New hack, `extrusion'.
812 * Some of the web sites that `webcollage' was using as
813 its sources changed formats; tweaked it to understand
815 * Added typeahead in the password dialog: if the screen
816 is locked, and you unlock it by typing a character,
817 that key will be automatically inserted in the
818 password dialog (unless it is Return, Enter, Space,
819 or a non-printing key like Shift.)
820 * Made `xmatrix' take a `-small' option, since some
821 folks with tiny screens prefer a smaller font.
822 Changes since 3.17: * New versions of `shadebobs', `lmorph', and `distort'.
823 * Added `ccurve', `blaster', and `bumps' hacks.
824 * Replaced `forest' hack with a rewritten version.
825 * Worked around a Xinerama server bug.
826 * Fixed a bug I introduced in 3.10 that caused some
827 hacks to print out superfluous warnings about not
828 having gotten enough colors.
829 * Made `sproingies' obey the `-delay' option.
830 * Fixed a portability bug in `shadebobs'.
831 * Made `webcollage' and `vidwhacker' use `xli' in
832 preference to `xv', if it is available.
833 * Added a new source of images to `webcollage'.
834 * If running under KDE, xscreensaver will add itself to
835 KDE's list of screensavers (via xscreensaver.kss.)
836 * Improved detection of GL libraries.
837 * Made the password dialog include the date and time.
838 Changes since 3.16: * New version of `webcollage' -- deals better with
839 corrupted images, and can use an http proxy.
840 * New hack, `xsublim' (run it in the background,
841 rather than adding it to the programs list.)
842 * The xscreensaver daemon was leaking a file descriptor
843 each time you edited your .xscreensaver file. Fixed.
844 Changes since 3.15: * New version of `shadebobs'.
845 * Improved image selection in `webcollage', and sped it
847 * Made configure find the right version of perl.
848 * Rewrote the CGI part of `webcollage'.
849 * `make clean' was deleting some things it shouldn't.
850 * Fixed a typo in the default programs list.
851 Changes since 3.14: * Added `webcollage' and `shadebobs' hacks.
852 * Added a `-stdout' arg to `vidwhacker' so that it can
853 be used in a pipeline.
854 * Made `petri' use less memory.
855 Changes since 3.13: * Various improvements to the Gtk port.
856 * Turned off PAM by default on Solaris, since PAM seems
857 generally to be misconfigured out-of-the-box.
858 * Made the `--without-gtk' configure option work.
859 * Made configure check the Gtk version number, since it
861 * Fixed a bug in the code that attempted to prevent
862 changes of screen resolution while the screen is
864 * Fixed a race condition in `xscreensaver-demo' that
865 could cause an X error at startup.
866 * Added `-transparent' option to `deluxe'.
867 * Added `petri' hack.
868 Changes since 3.12: * Ported `xscreensaver-demo' to Gtk.
869 * Made it possible to build Motif, Gtk, and Athena
870 versions of `xscreensaver-demo' in the same directory
871 without reconfiguring.
872 * Made `xscreensaver-demo' chase symlinks before writing
873 the .xscreensaver file, so that if .xscreensaver is
874 itself a symlink, the underlying file will be replaced
876 * Some Makefile and configure tweaks for Solaris and
878 * Made it possible to set the fire color in `xflame'.
879 * Made transparency work in TrueColor (for `goop' and
881 * Fixed a multi-head bug introduced by the virtual
883 Changes since 3.11: * Made it so that you can't scroll the screen while the
884 lock dialog is up (with XFree86 virtual viewports.)
885 * Fixed a bug in `flag' that caused bob's chin to get cut
886 off after a few iterations.
887 Changes since 3.10: * Made `xjack' be black-on-white-ish, so that it looks
888 less like a computer screen and more like the
889 typewritten paper it's supposed to be.
890 * New version of `pulsar'.
891 * Fixed Solaris compilation problem in `phosphor'.
892 * Made xscreensaver notice XFree86's virtual root window
893 hack, so that if the X server's root window is larger
894 than the monitor's displayable resolution, the screen
895 saver will limit itself to the area that actually
896 appears on the screen.
897 * Made the xscreensaver daemon do a better job of
898 picking the visual class that should be used for GL
899 programs. Less user intervention should be needed
900 now: you can use the logical visual name `GL' instead
901 of having to figure out by hand which one to use.
902 * Oops, the visual was defaulting to "best" instead of
903 "default", because the .xscreensaver file was not being
904 loaded quite early enough.
905 * Made configure figure out how to build icmp ping
906 support into the `sonar' hack automatically.
907 * Made warnings about not being able to read shadow
908 passwords not be printed if compiled with PAM support.
909 * Improved PAM startup diagnostics.
910 * Worked around the Solaris PAM bug that was causing
911 crashes there, so now PAM is turned on by default.
912 * Made configure detect the number of arguments that
913 pam_strerror() takes, since on Linux, this apparently
914 changed between 2.0 and 2.2, sigh.
915 * Made the /proc/interrupts kludge look for "PS/2 Mouse"
916 as well as "keyboard".
917 * Made xscreensaver notice when there has been a sudden
918 large jump in wall-clock time, and if so, lock right
919 away, instead of waiting for "lockTimeout" to expire
920 first. (Laptops need this for safer recovery from
922 * Added `-throttle' option to `xscreensaver-command'.
923 Changes since 3.09: * Added `phosphor', `xmatrix', and `pulsar' hacks.
924 * Fixed a bug in the color allocator that sometimes
925 caused `starfish' to fall back to monochrome.
926 * Reduced the amount of code that runs before root
927 privileges are disavowed: "normal" and "shadow"
928 passwords now do some initialization as root, but the
929 PAM and Kerberos authorization schemes will be
930 initialized while running as "nobody". Supposedly
931 this closes a potential security hole when using
933 * Added some more sanity checking to configure.
934 Changes since 3.08: * Added `compass', `squiral', `xflame', `wander',
935 `spotlight', and `critical' hacks.
936 * Added some new modes to `decayscreen'.
937 * Made `deluxe' work in monochrome.
938 * Generalized usage of the Double-Buffer server extension
939 in several hacks (`compass', `deluxe', `interference',
940 `kumppa', and `moire2'.)
941 * Fixed another visual-depth problem in `rd-bomb'.
942 * The screen saver will now defer blanking if neither
943 the keyboard nor the mouse could be grabbed. Instead,
944 it will just try again in a few minutes. This fixes
945 a bad interaction between xscreensaver and programs
946 like VMware that hold the mouse and keyboard grabbed
948 * Added a new erase mode (expanding spiral.)
949 Changes since 3.07: * Fixed some bugs in my port of `t3d'.
950 * Added `penetrate' and `deluxe' hacks.
951 * When linking against Motif 2.x, also link against XPM.
952 * Added support for using /proc/interrupts for idle
953 detection on Linux. Now xscreensaver shouldn't kick
954 in when the user is active on a non-X virtual console.
955 * Upgraded to autoconf 2.13.
956 Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
957 in properly; check for _Xsetlocale in -lXintl.)
958 * Portability fixes for sonar.c.
959 * Fixed a compilation problem when you have GL but don't
961 * Made configure notice when MesaGL requires -lpthread.
962 * Made `flame' ignore SIGFPE (not sure if this is the
963 right fix; it seems only to be needed on FreeBSD.)
964 * Kludged `rd-bomb' work on visuals that are of depth 24
965 but that *do not* support pixmaps of depth 32.
966 * Fixed `halo' to work properly in TrueColor.
967 * Changed `xscreensaver.spec' to install the hacks in
968 /usr/X11R6/lib/xscreensaver/ by default, since that's
969 where recent Red Hat distributions put them.
971 * Updated versions of `crystal', `hopalong', and `flow'
973 * Imported `demon' and `loop' modes from xlockmore.
974 Changes since 3.05: * Oops, the "default-n" visual descriptor was broken;
975 it was always installing a colormap if the
976 `installColormap' preference was set, meaning that
977 `xearth', `xv' and friends were using the wrong
978 colors on 8-bit systems.
979 * Turned off HAVE_PING in `sonar', since it compiles
980 on some Linux systems, but not others of similar
982 Changes since 3.04: * Fixed an off-by-1 in `distort'.
983 * Added `sonar' hack.
984 * New version of `glplanet' (with stars.)
985 * Made all hacks exit when you type `q' or `ESC' at them,
986 and made them obey the WM_DELETE_WINDOW ClientMessage.
987 * Fixed a nonfatal buffer overrun in lament (note:
988 lament still doesn't work with MesaGL 3.0: it dies in
989 lambda_textured_triangle1(), which is Mesa's bug, not
991 Changes since 3.03: * Added an `xscreensaver.spec' file, to make it easier
992 for other folks to generate RPMs.
993 * Made the password code work on HPUX in the situation
994 where: ``enhanced security'' is available; but not
995 used; but the user typed a password more than 8
996 characters long anyway. FTSOHPUX.
997 Changes since 3.02: * Made locking work when passwd aging is enabled.
998 * Added support for PAM (Pluggable Authentication
999 Modules.) It is still turned off by default, though,
1000 since it doesn't seem to work on Solaris 2.6, and has
1001 been behaving erratically on Red Hat 5.1.
1002 * Made each possible authentication method be tried in
1003 turn until one succeeds; this means that Kerberos is
1004 being used, we will first check Kerberos, and if that
1005 fails, will then consult the local password file.
1007 * Save and restore the bits under the passwd dialog,
1008 to avoid leaving a black rectangle behind when
1009 unlocking is cancelled.
1010 Changes since 3.01: * Not everyone has sys/select.h, sigh...
1011 Changes since 3.00: * Some fixes to `reflect'.
1013 * Made it log unsuccessful attempts to unlock the screen
1015 * Fixed a bug where `xscreensaver-demo' could be seeing
1016 a different programs list than `xscreensaver' did.
1017 Changes since 2.34: * The xscreensaver daemon no longer links against Motif
1018 or Athena: demo-mode and the preferences panel are no
1019 longer built in to the daemon, but are now handled by
1020 an external program, `xscreensaver-demo'.
1021 (I decided that this, along with the recent addition
1022 of the `.xscreensaver' config file, justified bumping
1023 the version number to 3.00, since this is a fairly
1024 major architectural change.)
1025 * Lines in the `*programs' resource may now begin with
1026 the character "-", meaning "don't run this hack."
1027 In this way, it's possible to disable a hack without
1028 throwing away the information about it (making it
1029 easier to change your mind later.) Eventually the
1030 preferences/demo mode GUI should represent this as a
1031 checkbox or something.
1032 * Fixed a short race condition where it was possible for
1033 xscreensaver to die with a BadWindow error if it was
1034 blanking the screen just as another window was being
1036 * Made it possible to disable specific modes in `bsod'.
1037 Changes since 2.33: * Fixed a bug that was making `pipes' generate way too
1038 many valves. Made the viewpoint in `pipes' be selected
1039 randomly instead of always being -10 degrees.
1040 * Fixed a bug in the XSHM code, in the case where the
1041 server supports the XSHM extension but is not the same
1042 machine as the client.
1043 * Made `rd-bomb' default to taking up the whole screen.
1044 * Made it not try to do fading/unfading if no PseudoColor
1046 * Initial attempt at supporting VT-locking (doesn't work
1048 * Eliminated the `captureStdout' resource; now
1049 `captureStderr' controls both streams.
1050 * Added `-capture-stderr' and `-no-capture-stderr'
1051 command-line arguments.
1052 * Added `glplanet' hack.
1053 * When a hack is selected with `xscreensaver-command
1054 -select', that hack will be used until further notice
1055 (until the saver turns off, or another activation
1057 Changes since 2.32: * Made `xscreensaver-command' print error messages:
1058 the xscreensaver daemon now responds to ClientMessage
1059 events by writing a response message on a window
1060 property, instead of just writing to its stderr.
1061 * Made the ~/.xscreensaver file be automatically reloaded
1062 when the file date changes.
1063 * The password dialog and splash screen no longer depend
1064 on Motif or Athena. This should clear up a number of
1065 focus problems, and is the first step on the path
1066 toward moving all of the Motif/Athena/whatever code
1067 out of the xscreensaver daemon, and into external
1069 * Don't complain about LessTif 0.86 any more, since the
1070 new password dialog makes that problem go away.
1071 * Configure tweaks for Irix 6.5, SunOS 5.something.
1072 * New `-reflect' option to `distort'.
1073 Changes since 2.31: * Added reading and writing of a ~/.xscreensaver file,
1074 so that the Preferences panel can save its settings.
1075 * New version of `rubik'.
1076 * Added `-select N' argument to `xscreensaver-command'.
1077 * Oops, left out some of the `bubbles3d' files...
1078 Changes since 2.30: * The cursor was invisible in the password dialog. Fixed.
1079 * Made configure warn against MesaGL 2.6.
1080 * Fixed X error at startup when using non-default visual.
1081 * New version of `crystal', `ant', and `atlantis' from
1083 * New hack, `bubble3d'.
1084 * Added some new modes to `bsod'.
1085 Changes since 2.29: * Changed the order in which -lSM and -lICE are linked
1086 to be after Motif instead of before (Lesstif on Irix
1088 Changes since 2.28: * Work around a bash bug in configure.
1089 * Tweaked HPUX paths again. FTSOHPUX.
1090 * Made configure recommend against LessTif 0.86, due
1091 to a bug in that version that causes a security hole
1092 in the screen locking code. LessTif 0.87 will fix it.
1093 * Made all of the `--with' options to `configure' accept
1094 a directory option as well (so that --with-motif=/FOO
1095 will add -I/FOO/include -L/FOO/lib). I believe this is
1096 the Configure Party Line of how do to such things.
1097 * Fixed a bug where the mouse was left un-grabbed
1098 after the first time the graphics hack was changed
1099 (simplified all of the mouse-grabbing logic.)
1100 * Maybe possibly perhaps made `vidwhacker' really not
1101 leave stray xv windows around. This time for sure.
1102 * Added a new erase mode (random dots fizzling out.)
1103 * Added `-prefs' argument to `xscreensaver-command',
1104 that brings up the Preferences dialog directly (it
1105 seems that nobody ever noticed the `Preferences' button
1106 on the Demo Mode dialog, maybe this will help.)
1107 * Added a splash screen. Turn it off with *splash:false.
1108 Changes since 2.27: * Better macsbug text in `bsod'.
1109 * New version of `distort' with many new modes.
1110 * Plugged a leak in `coral'.
1111 * Tweaked configure for HPUX.
1112 * Removed some compiler warnings.
1113 * More consistent usage of stderr versus stdout.
1114 * More diagnostics should an X error occur.
1115 * Fixed a possible crash in SGI-specific unfading code.
1116 Changes since 2.26: * Improved version of `distort'.
1117 * Made `lament' compile against OpenGL 1.0 (though it
1118 still requires 1.1 to work properly.)
1119 * Updated my email address and home page.
1120 Changes since 2.24: * Improved motion in `rd-bomb'.
1121 * Added XSHM (shared memory extension) support to the
1122 `distort', `interference', `moire', `rd-bomb', and
1123 `swirl' hacks, which speeds them up a bit.
1124 * Added `lament' hack.
1125 Changes since 2.23: * Tweaked the order of the -L options again.
1126 * Cleaned up configure's `--help' message.
1127 * Added `kumppa' hack.
1128 * Smarter maze-solving algorithm in `maze'.
1129 * Took `xlyap' out of the default list of hacks, since
1130 it's just incredibly buggy (and slow.) Maybe someday
1131 someone will fix it...
1132 * Added `distort' hack, but didn't add it to the default
1133 list (yet) because it's still too slow.
1134 * Made the Athena demo dialog look more like the Motif
1135 version; it has a text-entry field now, too.
1136 * Made the Athena password dialog echo asterisks, like
1137 Motif does, instead of using a flyspeck font.
1138 * Some random configure tweaks.
1139 * Added a `timestamp' resource that makes the `-verbose'
1140 messages include the time at which they were printed.
1141 Changes since 2.22: * The fix for SGI's ``scheme'' nonsense broke things, and
1142 let the user's "*background" resource show through.
1143 Fixed it in a different way.
1144 Changes since 2.21: * Added support for the DPMS server extension (Display
1145 Power Management System.)
1146 * Made configure advertize the `--enable-subdir' option a
1147 little more, since that seemed to cause some people
1148 stress. Also, made that directory be built into the
1149 xscreensaver executable, as a hardcoded prefix to
1150 $PATH. (Might help, shouldn't hurt.)
1151 * Made configure prefer the two-arg gettimeofday to the
1152 one-arg version, since AIX doesn't have any prototypes.
1153 * Made it work with Xaw3d (the 3D Athena library.)
1154 * Made `make install' create directories as necessary.
1155 * New version of lmorph from Sverre.
1156 * Added `crystal' and `discreet' hacks from xlockmore.
1157 * Added a new mode to `bsod'.
1158 Changes since 2.20: * Made `xscreensaver-command -time' use different words.
1159 (It now describes the two states as "screen blanked
1160 since..." and "screen non-blanked since..." instead of
1161 "active since..." and "inactive since..." which a lot
1162 of people interpreted as meaning the opposite of what
1164 * Improved some error messages, in the hopes of making
1165 the distinction between the xscreensaver and
1166 xscreensaver-command programs more obvious.
1167 * Rewrote (and reorganized) parts of the xscreensaver and
1168 xscreensaver-command manual pages.
1169 * Renamed xscreensaver's `-lock' command-line option to
1170 be `-lock-mode', to avoid confusion with the `-lock'
1171 option to xscreensaver-command, which does a totally
1173 * Removed xscreensaver's `-demo' command-line option for
1174 a similar reason; use `xscreensaver-command -demo'
1176 * Disabled SGI's ``scheme'' nonsense in a better way than
1177 fully-qualifying the background colors in every single
1179 * Fixed some other minor cosmetic problems when *sgiMode
1181 * Fixed an X error in `bsod -root' (how ironic...)
1182 Changes since 2.19: * Fixed a bug that caused the mouse to sometimes not be
1183 grabbed properly (meaning the window manager menu could
1184 pop up over the demo-mode display.)
1185 * Fixed a bug that made the stderr output sometimes get
1187 * Fixed a bug that made the demo-mode scrollbar move too
1189 * Protected against a possible buffer overflow.
1190 * Made `vidwhacker' not leave stray xv windows around.
1191 * New version of `ant' so that Bagley doesn't calve.
1192 * Make configure on AIX get XShm from the right library.
1193 Changes since 2.18: * One file was missing from the tar file. Fixed.
1194 Changes since 2.17: * Oops, atlantis wasn't being built by default. Fixed.
1195 * Added `epicycle' hack.
1196 * Added `interference' hack.
1197 * Added `truchet' hack.
1198 * Added `bsod' hack.
1199 * Added some new modes to `vidwhacker'.
1200 Changes since 2.16: * Added a -window-id argument to most hacks, so that they
1201 can draw on arbitrary externally-provided windows.
1202 * Synched with xlockmore 4.11a01.
1203 * Added `flow' hack.
1204 * Added `atlantis' GL hack.
1205 * Renamed `puzzle' hack to `jigsaw', since xlock already
1206 had a different mode called `puzzle'.
1207 * Made it self-configure properly when Motif 2.1.0 is
1208 being used (requires -lXp now, sigh...)
1209 Changes since 2.15: * Made `flag' able to do XPM images.
1210 * New look for the xscreensaver logo (`xroger').
1211 * Fixed compilation error on Suns with adjunct passwords.
1212 * Got multi-architecture builds working again.
1213 * Some configure tweaks for building on HPUX and Solaris.
1214 * Fixed bug in decayscreen.
1215 * Fixed typo in passwd.c.
1216 * Made `cynosure' not die when colormap is full.
1217 Changes since 2.14: * Added `cynosure' hack.

1219 * Tweaked `erase.c' some more.
1220 * Made unfading a bit smoother.
1221 * Added `vidwhacker' hack (not installed by default.)
1222 * Added `stairs' hack.
1223 * Split `escher' into `cage' and `moebius', as per
1225 * Changed subprocess handling to use sigaction() instead
1226 of signal() if it's available (this is necessary for
1227 SCO but should work fine on other systems too.)
1228 * Various other tweaks.
1229 Changes since 2.13: * Better fix for the Motif drag-and-die lossage.
1230 * Put in some kludges to work around a LessTif bug.
1231 * XScreenSaver is known to work with LessTif 0.82 now.
1232 * Made fading work on high-end SGI video hardware.
1233 * Fixed another SGI-specific bug in screen grabbing;
1234 will the madness never cease?
1235 * Fixed another crash in `xlyap'.
1236 Changes since 2.12: * Made `decayscreen' do directions other than down.
1237 * Improved `puzzle'.
1238 * Fixed a crash in `xlyap'.
1239 * Added CDE info to the man page, removed `cde.txt'.
1240 * Configure tweaks for Zippy.
1241 * Turned off the signal handling in `bubbles' because
1242 it was sometimes failing to die.
1243 * Added `hacks/xscreensaver-sgigl.c' to make it possible
1244 to run SGI's ElectroPaint hack (/usr/demos/bin/ep)
1245 with xscreensaver. Finally!
1246 * Fixed a buffer overrun in the locking code that some
1247 wily, malicious cracker must have slipped in.
1248 * Disabled Motif drag-and-drool in the dialog box
1249 buttons, since it's broken in some old versions of
1251 Changes since 2.11: * Added `README.debugging'.
1252 * Added `puzzle' hack.
1253 * Added `xlyap' hack.
1254 * Added `default-n' as a visual name, so that one can
1255 have -install on by default, but turn it off for
1256 certain poorly-behaved hacks (like xv.)
1257 * Added support for grabbing frames of external video
1258 (on SGI) to the screen-grabbing hacks (decayscreen,
1259 slidescreen, slip, blitspin, and puzzle.)
1260 * Improved look of tiles in `slidescreen'; fixed its
1261 color allocation problem.
1262 Changes since 2.10: * Tweaked `blitspin', added it to the default list.
1263 * Added `lissie', `mountain', `triangle', `worm',
1264 `rotor', and `ant' from xlockmore.
1265 * Updated `sierpinski', `galaxy', and `lisa'.
1266 * Thickened the lines in `braid' and `lmorph'.
1267 * Updated VMS makefiles.
1268 * Renamed `fract' to `vines'.
1269 * Added `xjack' hack.
1270 * Made a few more hacks use erase.c, and added a few
1272 * Fixed compilation problem with Sun's version of OpenGL.
1273 * Added ability to use sigaction() instead of signal()
1274 to work around a SCO kernel bug.
1275 Changes since 2.09: * Fixed colormap bugs in `rd-bomb'; sped up `coral'.
1276 * Configure tweaks for *BSD.
1277 Changes since 2.07: * New hacks `rd-bomb' and `coral'.
1278 * New version of `maze' with some new algorithms.

1288 Changes since 2.05: * Merged in VMS support from Patrick Moreau.
1289 Changes since 2.04: * Fixed a MIT-SCREEN-SAVER-related crash, and tweaked
1290 configure to detect the extra-random -Xss library.
1291 Changes since 2.03: * HP configure tweaks. Detect and warn about LessTif.
1292 * Fixed low-color behavior of `goop', `pyro', `starfish',
1293 `greynetic', `flame', `halo', and `moire'.
1294 Changes since 2.02: * Fixed flicker in `pipes'. Fixed 3d in `bouboule'.
1295 * Added `munch' hack.
1296 * Added basic dependencies to the Makefile.in files.
1297 Changes since 2.01: * Fixes for compiling with the MIT saver extension.
1298 * Made the yow/fortune program be a configure option.
1299 * Various configure tweaks.
1300 Changes since 2.00: * Added `goop' and `starfish' hacks.
1301 * Added colomap cycling to `halo'.
1302 * Made `attraction' use the new colormap allocator.
1303 * Added better $PATH diagnostics.
1304 * There was a bug in frand! Color selection should be
1306 Changes since 1.34: * Converted to use `configure' instead of `imake'.
1307 * ANSI C is now required.
1308 * Added Kerberos locking support, from Nat Lanza.
1309 * Made the stderr text use overlay planes, if possible.
1310 * Reworked the xlockmore compatibility stuff again.
1311 * Added `gears', `superquadrics', `escher', `pipes',
1312 and `sproingies' hacks (depend on OpenGL.)
1313 Changes since 1.33: * Fixed some bugs, made fading be a little smoother.
1314 Changes since 1.32: * Made it work with multi-headed displays.
1315 * Generalized sub-process management (Unix sucks!)
1316 * Added interactive mouse frobbing to Julia.
1317 * Added (untested) support for HPUX shadow passwords.
1318 * Made normal non-shadow passwords be checked if the
1319 shadow passwords aren't accessible for some reason.
1320 Changes since 1.31: * Removed *colorPrograms and *monoPrograms resources:
1321 made it possible to specify the desired visual on a
1323 * Cleaned up / restructured the driver: no more globals.
1324 * Made the Motif and Athena dialogs share more code.
1325 * Probably fixed some Athena colormap-installation bugs.
1326 * Fixed screen grabbing (cmap) on SGI 12-bit PseudoColor.
1327 * Fixed divide-by-zero in bright random colormaps.
1328 * Added an improved version of xlock's `flag' hack.
1329 * Made unfading work better, and not flicker on SGIs.
1330 * Added `sphere', `forest', `lisa' hacks from xlockmore.
1331 * Added (untested) support for SunOS Adjunct passwords.
1332 Changes since 1.30: * Improved colors and colormap cycling of many hacks.
1333 * Cleaned up xlockmore compatibility layer.
1334 * Made `blitspin' able to grab an image off the screen.
1335 * Ported `swirl' and `bouboule' hacks from xlockmore.
1336 * Made the driver more careful about not leaving bits on
1337 the screen, or allowing other windows to raise
1338 themselves: it now re-blanks the screen every so often.
1339 * Added `-time' option to `xscreensaver-command'.
1340 * Improved SGI screen-grabbing some more: now it can grab
1341 TrueColor screens into PseudoColor windows and have the
1342 colors still come out semi-reasonably.
1343 Changes since 1.29: * Made `slidescreen' and `decayscreen' work better on
1344 SGIs when windows of different visuals are present, by
1345 using the XReadDisplay() extension to get a true 24-bit
1346 image out of the frame buffer.
1347 * Made `noseguy' be in color, if compiled with XPM.
1348 * Ported `braid', `drift', `fract', `galaxy', `grav',
1349 `ifs', `julia', `laser', `lightning', `penrose',
1350 `sierpinski', `slip', `spiral', and `strange' hacks
1352 * Merged `hopalong' hack with a more recent version.
1354 Changes since 1.27: * Added `deco', `moire', and `kaleidescope' hacks.
1355 * Merged in support for non-Motif locking and demo mode.
1356 * Made `blitspin' and `bubbles' work in TrueColor.
1357 * Fixed a stupid bug I introduced in `imsmap'.
1358 * Added `poly' and `gravity' options to `qix'.
1359 Changes since 1.26: * Added support for SGI SCREEN_SAVER extension.
1360 * Made `fade' and `unfade' work on 8-bit SGIs.
1361 * Made the dialog boxes more Motify.
1362 * Added `bubbles' hack.

1364 * Added viscosity and mouse-control to attraction.
1365 * Fixed possible bad color choices in qix and attraction.
1366 * Added ramp-mode to halo.
1367 * Added a new RNG, which is faster and more portable
1368 than using the RNG in libc.
1369 * Made locking work on SCO.
1370 * Various other minor tweaks that I don't remember.
1371 Changes since 1.24: * Made it capture the stdout/stderr of its subprocesses
1372 and present them on the screensaver window itself.
1373 * Made demo mode work correctly with non-default visuals
1374 and color maps, instead of always using the defaults.
1375 * Added -visual argument to all included screenhacks.
1376 * Support for the R6 MIT-SCREEN-SAVER server extension.
1377 * Made the demo mode list scroll properly.
1378 * Added `pedal' hack.
1379 Changes since 1.23: * Fixed some private-colormap oddities in slidescreen,
1380 decayscreen, and xroger. Fixed apparent conservation-
1381 of-mass problem in pyro; made the shrapnel round.
1382 Changes since 1.22: * Minor tweaks for IRIX5; fixed locking race condition.
1383 Changes since 1.21: * Minor tweaks for X11R6.
1384 * Fixes for non-default visuals.
1385 Changes since 1.20: * Fixed bug in color blitspin; added default image.
1386 * Added diagnostics to noseguy. Fixed off-by-one
1387 error in flame. Added some missing casts.
1388 Changes since 1.18: * Added `flame' hack.
1389 * Fixed a minor Motif dialog text field bug.
1390 * Fixed yet another XPointer-not-defined-in-R4 bug.

1398 Changes since 1.14: * Broke the driver up into more source files.
1399 * Moved the hacks into their own directory.
1400 * Made all `time' parameters accept the 00:00:00 syntax,
1401 so that even the parameters which are normally read as
1402 minutes can be specified in seconds.
1403 * Added colormap cycling to `imsmap'.
1404 * Made hyper work with K&R compilers.
1405 Changes since 1.13: * Added `orbit' option to `attraction' hack.
1406 * Added `lock-timeout' option.

1411 Changes since 1.4: * Works when run from XDM before anyone logs in.
1413 * Can use `xv' as a slideshow without using up colormap
1414 entries while the screen is not blanked.
1415 * Fixed a BadDrawable error in non-XIdle mode.
