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

184 * Arrgh, more RANDR noise! Fixes this time for rotated screens, and
185 for systems where RANDR lies and says the screen size is 0x0.
186 * When the password dialog has timed out or been cancelled, don't pop
187 it right back up a second time.
188 * Password timeouts/cancels don't count as "failed logins".

221 a new image every few minutes.
222 * Added an ATM crash to `bsod'.
224 5.05 * New hacks, `cubicgrid', `hypnowheel', and `lcdscrub' (which isn't
225 really a screen saver).
226 * Updates to `m6502' and `gears'.
227 * Fixed double-buffering problems in `cubestorm' and `noof'.
228 * Better handling of horizontal scroll wheels.
229 * Attempt to work around latest Xinerama braindamage: if the server

235 hacks to fail on some systems.
236 * Hopefully fixed font-related System Preferences crashes in MacOS
238 * The recent PAM changes broke the "Caps Lock" warning in the password

242 recent PAM changes...)
243 * New hacks, `moebiusgears', `abstractile', and `lockward'.
244 * Rewrote `gears' to use better (involute) gear models, and to be more
246 * Minor updates to `cwaves', `voronoi', `deco', `glcells', `rd-bomb',

265 `fliptext', and `carousel'.
266 * Enabled multi-threaded OpenGL on MacOS.
268 5.01 * Backed out recent locale-related changes, since they broke far more
269 things than they fixed.
270 * Fail gracefully with ridiculously small window sizes.
271 * `xflame' and `flag' ignore bitmap option on MacOS.
272 * `speedmine' prefs work on MacOS.
273 * Better explosions in `boxed'.
274 * More dynamic motion in `sproingies'.
275 * More options in `flipflop'.
276 * Minor updates to `topblock'.
277 * Various other minor fixes.
279 5.00 * Ported to MacOS X! (10.4.0 or newer)
280 * API change: instead of providing a single screenhack() function that
281 does not return, screen savers using the screenhack.h framework must
282 now provide "init" and "draw one frame" functions instead. All
283 bundled savers have been updated; third-party patches will need
285 * All image-loading happens asynchronously.
286 * xscreensaver-getimage-file caches the contents of the image
287 directory for a few hours, so consecutive runs won't have to re-list
288 the whole directory tree.
289 * New hacks, `topblock' and `glschool'.
290 * Removed `xteevee' (superceded by `xanalogtv').
291 * Added variable-sized puzzle pieces to `jigsaw'.
292 * Changes to the defaults and command-line options of many hacks to
293 make the .xml files more consistent.
294 * Reap zombies in `glslideshow' and `carousel'.

297 * `endgame' has higher resolution chess-piece models.
298 * `webcollage' takes a -directory option to get images from a local
300 * The RPM spec file no longer auto-restarts xscreensaver when a new
301 version is installed. Restart it manually.
303 4.24 * New versions of `cube21', `glsnake', `celtic'.
304 * Backed out a DPMS-related patch that cause desktop flickering with
306 * Fixed startup crash in getgroups() when running setuid.
307 * Default to not displaying stderr on the saver window.

314 * New versions of `tangram', `webcollage', `hypertorus', `polytopes',
316 * `sonar' is now quiet about unresolvable hosts.
317 * Minor corrections to BASIC code in `apple2'.
318 * xscreensaver-demo now provides an RPM clue when none of the hacks
319 seem to be installed.
320 * Don't install `ant' by default, since there is some Java tool of
321 that name, which was causing confusion. And also it's boring.
322 * Made screen grabbing work again on MacOS 10.4.2.
323 * No longer prints bogus warnings about ClientMessages intended for
325 * Ignore unprintable characters in passwd entry field.
326 * Fixed yet another cross-host-display image-loading endian problem.
327 * `xscreensaver-command -watch' and `-time' now work on 64-bit
330 4.22 * Fixed a bug in the new mouse-motion code that caused the screen to

332 * New hacks, `interaggregate', `antmaze', `tangram', and `crackberg'.
333 * Minor tweaks to `fiberlamp', `ifs', `slidescreen', `zoom', `sonar',
334 `fireworkx', `whirlwindwarp', `bubble3d', and `rd-bomb'.
335 * Added motion blur to `blinkbox'.
336 * `bsod' now includes Longhorn's "RSOD", and OS/2.
337 * Fixed `-wireframe' usage in most hacks and man pages.
339 4.21 * New hack: `fliptext'.
340 * Changed default configure installation directories: /usr/bin/ for
341 xscreensaver, etc.; /usr/libexec/xscreensaver/ for hacks;
342 /usr/share/xscreensaver/config/ for xml files.
343 * All the text-manipulating screen savers can have their text source
344 configured via `xscreensaver-demo' now.
345 * xscreensaver.spec now builds three RPMs: base (no hacks); extras (2d
346 hacks); and gl-extras.
347 * Added `-program' and `-front' option to `gltext'.
348 * Added `-shells' to `molecule'.
349 * Fixed text-alpha glitch in `carousel'.
350 * New `pacman': the ghosts can be killed now.

352 instead of scaled on machines that can't do large textures.
353 * `webcollage' can hit Flickr now.
354 * New (rewritten) implementation of `ifs'.
355 * The unlock dialog can be made to have a "New Login" button that will
356 run `gdmflexiserver'. Experimental!
357 * Fixed non-ASCII display bug in `starwars'.
358 * Configure finds a default for imageDirectory.
359 * "xscreensaver-command -lock" now works even if in "screensaver
361 * If a bad password is typed while CapsLock is on, the unlock dialog
362 says "CapsLock?" instead of "Sorry".
363 * Mouse motion only counts as activity if the mouse moved more than 10
364 pixels (so the screen won't unblank every time you bump your desk.)
365 * New mode option "random-same": if you have multiple monitors, this
366 will run the *same* randomly chosen hack on each screen, instead of
367 different ones on each.
369 4.20 * New hacks, `fiberlamp', `boing', `boxfit', and `carousel'.
370 * Rewrote `glslideshow' again: should be faster now.

389 4.17 * New hacks, `anemotaxis' and `memscroller'.
390 * Fixed a bad bug that caused `vidwhacker' to never die.
391 * Fixed normals and lighting in `polyhedra'.
392 * Don't reuse the window when changing hacks (to work around bugs in
393 some GL implementations.)
394 * Made `xscreensaver-getimage-file' skip thumbnail-sized images.
395 * Fixed endian problem in `barcode' on non-x86.
396 * Updates to `webcollage', `apple2', `fuzzyflakes', `atunnel', and
398 * Timing tweaks to `bubble3d', `bouncingcow', `engine', `gltext',
399 `lavalite', `molecule', `spotlight', `sballs', `boxed', `blinkbox',
401 * Configure updates for Fedora core 2 / xorg 6.7.0.
402 * Compile without warnings under gcc 3.3.3.
403 * I give up: don't blank or lock the screen if we can't get a keyboard
404 grab. In that case, both choices are bad.
406 4.16 * New hacks, `polyhedra', `fuzzyflakes', `antinspect', and
408 * Minor updates to `webcollage', `bsod', `endgame', `antspotlight',

414 * Made `xscreensaver-getimage -file' still work even if imageDirectory
416 * Convert Latin1 to ASCII in `starwars' and `phosphor' (since the GLUT
417 font only has ASCII glyphs.)
418 * Fixed randomization in `noof'.
419 * Added "GetViewPortIsFullOfLies" preference to work around
420 longstanding XFree86 bug #421.
421 * Made `sonar' subnet pinging work properly on bigendian machines
424 4.15 * New hacks, `wormhole', `mismunch', `noof', and `pacman'.
425 * `phosphor' and `apple2' include vt100 emulators now: this means you
426 can do "phosphor -program top", or can use either program as an
427 xterm replacement: "apple2 -text -fast -program 'xemacs -nw'".
428 * `analogtv' (and related) fill the screen better.
429 * The '-gradient' option works in `atlantis' now.

441 * New version of `endgame'.
442 * Screen grabbing works on MacOS X.
443 * Various minor fixes.
445 4.13 * On Xinerama systems, xscreensaver now runs one hack on each monitor
446 (just like in "real" multi-head mode) instead of running one hack
447 stretching across all the screens. Note that for this to work with
448 any 3rd party screensavers, they must update their "vroot.h" file.
449 * `webcollage' and `vidwhacker' display images using
450 `xscreensaver-getimage' now.
451 * Added `ljlatest' script for use with `starwars' and `phosphor'.

468 * Added some Matrix Reloaded text to `xmatrix'.
469 * Updates to `webcollage', `eruption', `jigglypuff', `metaballs', and
471 * Completely ignore the `memoryLimit' setting now, since it was still
472 causing people GL grief.
473 * Various minor fixes.
475 4.09 * New hacks, `flyingtoasters', `bouncingcow', `jigglypuff', and
477 * More models in `engine'.
478 * Rewrote `xscreensaver-getimage' to remove reliance on external image
479 loaders (xv, chbg, xloadimage, etc.) and to reduce flicker when
481 * Made `gflux' and `flipscreen3d' be mouse-spinnable.
483 4.08 * New hacks, `atunnels' and `piecewise'.
484 * Physics improvement in `fluidballs'.
485 * Various fixes for XDarwin systems (X11 on MacOS X.)
486 * Added -clock option to `barcode'.
487 * Minor fixes to `endgame', `flurry', `flipscreen3d', and `gflux'.

497 * Updated `glplanet' so the sun sets in the west.
498 * Updated `sproingies' with smooth, unsegmented surfaces.
499 * Fixed Perl version-sensitivity in `xscreensaver-getimage-file'.
500 * Fixed GTK2 scrolling bug in `xscreensaver-demo'.
502 4.06 * New hack, `glblur' (disabled by default, since it requires fast
503 OpenGL texture support.)
504 * New hack, `halftone'.
505 * Updates to `endgame', `queens', `bumps', `glplanet', `engine', and
507 * New version of `menger' that uses far fewer polygons.
508 * Fixed minor bug in `critical' that could cause some bogus X servers
510 * Better labels in `molecule': the labels now appear to be attached to
511 the atoms, instead of floating in front of the whole scene.
512 * Fixed bug that could rarely cause GL hacks to fail to double-buffer
513 (causing intermittent flickering.)
514 * Fixed a relative-URL-parsing bug in `webcollage'.
515 * Fixed a bug that (sometimes) caused the window manager close box to
516 kill `xscreensaver-demo' with a crash instead of a graceful exit.
517 * Updated xscreensaver.pam to the Red Hat 7.3 way.
518 * More Gnome2-related configure crap.
519 * Updated to latest `config.guess' and `config.sub'.

522 * Added MacOS X kernel panic to `bsod'.
523 * Fixed a bug in `bsod' (all bsod bugs are ironic.)
524 * Fixed a bug that caused `xscreensaver-gl-helper' to print a nonsense
525 visual ID with some versions of `printf': this could cause GL
526 programs to display incorrectly (e.g., flickery.)
528 4.05 * More `configure' tweaks to try and get things working on systems
529 that both Gtk 1.x and 2.x installed.
530 * New hack, `endgame'.
531 * Minor updates to `gltext'.
533 4.04 * Support for GTK 2.x / GNOME 2.x.
534 * The `configure' script will now use `pkg-config' if you have it, in
535 preference to `gtk-config', etc.
536 * New hacks, `lavalite', `queens', and `anemone'.
537 * Minor updates to `spheremonics', `gltext', `xmatrix'.
538 * You can use the mouse to manually spin most of the GL hacks now
539 (when they are displaying in a window.)
540 * Fixed a bug in `webcollage' (due to recent Alta Vista url changes)
541 that was causing it to try and load incorrect image URLs.
542 * Made `xscreensaver-getimage' use gdk_pixbuf if it is available: this
543 means that those hacks that load images will no longer rely on "xv",
544 "xloadimage", etc. This will close a race condition that could
545 sometimes cause your desktop background to be changed; and also
546 makes it possible for those programs to operate on image files when
547 running in windowed mode.
548 * `webcollage' can now be used in conjunction with `driftnet' to
549 display images snooped from your local ethernet instead of obtained
551 * Added man pages for all the hacks that didn't have them.
553 4.03 * New hack, `spheremonics'.
554 * Minor updates to `webcollage', `cage', `moebius', `morph3d',
555 `boxed', `circuit', and `helix'.
556 * `pulsar' and `extrusion' can now load texture JPEGs.
557 * `rubik' now does non-square cubes.
558 * `fluidballs' now does various sizes of balls.
559 * `menger' and `sierpinski3d' now also show polygon counts in -fps
561 * `molecule' displays real subscripts in the formulae.
562 * GTK internationalization/localization support.
563 * Better detection of the various versions of libxml.
564 * Upgraded to autoconf 2.53 (from 2.13.)
566 4.02 * Plugged a few minor leaks in `xscreensaver' and `xscreensaver-demo'.
567 * New hacks, `cubenetic' and `fluidballs'.
569 * Fixed sphere projection error in `glplanet'; installed a better
571 * Added Win2K and MacOS 1 crashes to `bsod'.
572 * Put back previous (better) version of `forest' that was
573 accidentially downgraded in the last release.
574 * New version of `bumps'.
575 * Made FPS computation in GL hacks more efficient: it will influence
576 the results less, thus resulting in higher (but more accurate)
577 reported frame rates.
579 4.01 * New hacks: `twang', `glsnake', `boxed', `sballs', and
581 * New hacks `apollonian', `euler2d', `juggle', `polyominoes' and
582 `thornbird', from xlockmore.
583 * Merged recent xlockmore changes into `ant', `braid', `demon',
584 `discrete', `drift', `fadeplot', `forest', `grav', `hopalong',
585 `ifs', `laser', `lightning', `lisa', `lissie', `loop', `mountain',
586 `penrose', `rotor', `sierpinski', `slip', `sphere', `spiral',
587 `strange', and `vines'.
588 * Fixed the `gltext' bug that sometimes caused horizontal lines to
589 vanish again. This time for sure.
590 * Sped up `webcollage' by adding a C helper program to replace the PPM
591 pipeline. It also pastes images semi-transparently now.
592 * Added support for the gdk_pixbuf library: if this lib is available,
593 then `blitspin', `xflame', and `flag' can load GIF, JPEG, and PNG
594 images in addition to XPM and XBM.
595 * Fixed a rare race condition where the desktop-grabbing hacks could
596 sometimes leave the screen wedged, if the user moved the mouse
597 exactly when they were grabbing the screen image (it would un-wedge
598 the next time the saver timed out or was activated.)
599 * Fixed incorrect colors in the screen-grabbing GL hacks (`gflux' and
601 * Made SIGHUP restart the daemon process (though using
602 `xscreensaver-command -restart' is still the preferred way.)
603 * Tweaks to `xspirograph'.
604 * Minor configure and portability tweaks.
606 4.00 * Redesigned `xscreensaver-demo' GUI: it now includes small-preview
607 and per-hack configuration dialogs.
608 * Added three new modes of operation: `One Screen Saver', `Blank
609 Screen', and `Don't Blank' (in addition to the historical `Random
611 * Configure now defaults to installing the hacks in
612 <prefix>/lib/xscreensaver/ instead of <prefix>/bin/. (Most distros
613 already did it this way.)
614 * New GL hacks, `menger', `engine', `flipscreen3d'.
615 * Made `sierpinski3d' be more colorful.
616 * New versions of `xmatrix' and `nerverot'.
617 * Fixed a bug in `starwars' that made the font be drawn with thin
619 * Fixed a bad colormap bug in `crystal' that could make *subsequent*
621 * Made `gflux' able to grab screen images (`-mode grab').
622 * Updated `webcollage' for recent search engine changes.
623 * Removed most command-line options to `xscreensaver': just edit the
624 ~/.xscreensaver file instead.
625 * Improved behavior on multi-screen and Xinerama systems: the mouse
626 now stays on the screen where the user left it, and the password and
627 splash dialogs always appear on the screen that has the mouse.
628 * Made the splash dialog use more Gtk-like colors; made it have only
629 two buttons, "Settings" and "Help".
630 * Made `sonar' understand `.ssh/known_hosts2' format files, and be
631 better about stripping out illegal addresses.
633 3.34 * Turned `memoryLimit' off by default, sigh. Apparently some versions
634 of the GL libraries (appear to) allocate hundreds of megs for every
635 GL program, so `memoryLimit' was causing GL programs to malfunction
636 or crash on those systems.
637 * Improved fading on TrueColor XFree86 4.1.x systems.
638 * New GL hack, `circuit'.
639 * Added `fuzz' mode to `decayscreen'.
640 * New version of `whirlygig'.
641 * Added links to `xplanet' and `sphereEversion'.
642 * Fixed rare race condition that could make `sonar' hang.
643 * Fixed potential crash in `speedmine'.
644 * Made `xscreensaver-demo' not crash when imageDirectory was set to a
645 non-existent directory.
646 * Made `xscreensaver-getimage-video' invoke XawTV's `streamer' program
648 * Made `phosphor' and `starwars' deal with CR, LF, or CRLF line
650 * Changes for Cygwin compilation environments.
651 * Made `sonar' compile on systems that can't ping.
652 * Configure changes for HPUX 10.20.
653 * Made PAM code work on Red Had 4.2 systems.
654 * Made `xscreensaver-command -deactivate' work when the saver is not
655 active: what that does is reset the idle timer, as if keyboard input
656 had been detected. This was added for the benefit of people writing
657 DVD-playing software: they can now prevent the screensaver from
658 kicking in by sending a -deactivate message once a minute while the
659 movie is playing and not paused.
660 * Various minor portability tweaks.
662 3.33 * New hacks, `speedmine' and `whirlygig'.
663 * Sped up `pyro', made the explosions look a bit better.
664 * Added better stars to `glplanet' and `starwars'.
665 * Many internal changes to `webcollage'.
666 * Some new options to `attraction'.
667 * Minor fix to `noseguy' to avoid un-erased pixels.
668 * Rewrote the screen-eraser effects so that they complete in the same
669 amount of time regardless of how slow your X server is (some of them
670 were glacial on servers with slow blitting.)
671 * Fixed a potential free memory reference that could sometimes cause a
673 * Possibly fixed a problem that could cause the daemon to crash with
674 an X error. I was never able to reproduce this problem, but I think
675 I might have figured out what caused it.
676 * Worked around a problem that caused PAM authentication to fail on
677 some Red Hat 7.x systems.
678 * Added a `memoryLimit' parameter that controls the amount of memory a
679 graphics hack may allocate: if they try to allocate more than this,
680 malloc() will fail (and they will exit or (safely) crash, rather
681 than hogging memory.) Default is 50M.
682 * Made `gnome-help-browser' be the default way to display man pages in
683 `xscreensaver-demo', if running on a GNOME system.
685 3.32 * The image-manipulating hacks (`slidescreen', etc.) can now operate
686 on randomly chosen image files from disk, or on frames captured from
687 the system's video input, instead of (or in addition to)
688 manipulating images of the desktop.
689 * Rewrote `vidwhacker' to use the new image-grabbing mechanism.
690 * Made fading work on TrueColor XFree86 4.x systems.
691 * Fixed a subtle rendering bug in `atlantis' (the fish were inside
693 * Made `atlantis' have a texture simulating light reflections from the
694 surface of the ocean.
695 * Fixed up label placement in `molecule'.
696 * Better color bars in `xteevee'.
697 * Made `install-strip' not try to strip scripts.
699 3.31 * Put in more sensible defaults for DPMS, and updated the
700 documentation to reflect the fact that all your DPMS settings are
701 now belong to xscreensaver.
702 * Fixed the `xscreensaver.spec' file so that `--force' is no longer
704 * New versions of `rotzoomer' and `nerverot'.
705 * Fixed an OSF/1 compilation problem in `molecule'.
707 3.30 * New hacks, `molecule', `dangerball', and `rotzoomer'.
708 * New version of `gflux'.
709 * Made `gltext' able to display the current time.
710 * Fixed a floating-point-precision problem in `gltext' that sometimes
711 caused horizontal lines to vanish.
712 * Removed the `-window-id' option from the hacks: it never worked
713 right, and was unnecessary.
714 * Made the `starwars' hack use thicker lines, antialias the text, and
715 fade out at the far edge instead of just dropping off.
716 * Fixed an SHM segment leak in `moire'.
718 3.29 * Better rendering of the new logo.
719 * New hack, `gltext'.
720 * Added `-planetary' option to `gears', to draw a different kind of
722 * Made motion and rotation be smoother in `gears', `glplanet',
723 `moebius', `rubik', and `sierpinski3d'.
724 * Improved coloration in `sierpinski3d'.
725 * Made the GL hacks react to window size changes.
726 * Made most of the GL hacks take a -fps option (like `pulsar' did), so
727 you can use them to benchmark your 3D hardware.
728 * Fixed the previous fix to `sonar'.
729 * Minor fix to `nerverot'. Made sonar able to ping hosts on DEC OSF1.
730 * Eliminated a bogus "didn't get enough colors" warning in some of the
733 3.28 * New logo for xscreensaver!
734 * New hacks, `starwars' and `stonerview'.
735 * Made the motion of the bouncing ball in `stairs' be a little less
737 * Made newly-added screenhacks be added to .xscreensaver
738 automatically: if there are hacks in the app-defaults file that are
739 not also in ~/.xscreensaver, they will be added to the end of the
741 * Redid the `Screensaver Options' part of the control panel;
742 xscreensaver now lets you configure your DPMS settings.
743 * Fixed some Makefile problems with non-GL builds.
744 * Fixed detection of MesaGL for version 3.3.
745 * Better workaround to Red Hat 7.0's broken gcc.
746 * Added Sparc Solaris kernel panic to `bsod'.
748 3.27 * New hacks: `zoom' and `whirlwindwarp'.
749 * Fixed a free-memory-reference bug in `sonar'.
750 * Better error handling when there are no suitable GL visuals.
751 * Added diagnostic dialog when xscreensaver-demo is unable to launch
752 xscreensaver (e.g., when running as root.)
753 * Fixed a bug that caused screenhack argument changes to be ignored
754 when xscreensaver-demo was running as root (if "root" and "nobody"
755 have different home directories.)
756 * Made the programs default to ":0" if $DISPLAY is unset.
757 * Made the `-verbose' output include information about which server
758 extensions were supported at compile time.
759 * Worked around Red Hat 7.0's broken gcc 2.96.
760 * Updated default delays on the GL hacks to look better on machines
761 with super-fast 3D hardware.
762 * Install `screensaver-properties-capplet' to work around the usual
763 egregious GNOME lossage.
765 3.26 * Added "enabled" checkboxes in the list of hacks in xscreensaver-demo
767 * New hacks `hyperball', `xrayswarm', and `gflux'.
768 * New versions of `nerverot', `galaxy', and `hypercube'.
769 * Small fixes to `phosphor', `shadebobs', `xflame', and `sonar'.
770 * Added external helper program `xscreensaver-gl-helper' to figure out
771 which X visual to use for OpenGL programs.
772 * Configure updates for XFree86 4.0, and for BSD.
773 * Made it be more tolerant of bogus /etc/group files.
774 * When installing the PAM config file, first try to just copy an
775 existing "xdm" or "login" config file, so that xscreensaver does
776 authentication in the same way as the rest of the system.
778 3.25 * New hack, `nerverot'.
779 * Added BSD kernel panic to `bsod'.
780 * New version of `shadebobs'.
781 * New version of `petri'.
782 * Updated `webcollage' to handle recent Altavista URL format changes;
783 made it search the AP photo gallery.
784 * Revamped command-line options of `sonar' and made it properly handle
786 * The `bubbles' hack can now trickle up or down the screen.
787 * The `xsublim' hack can now read its text from programs.
788 * Support for GLE version 3 in `extrusion'.
789 * Fixed compilation problems in `maze'.
790 * Fixed a rare crash in `flow'.
791 * Fixes for minor installation problems.
793 3.24 * Added `-ignorant' option to `maze' hack.
794 * Updates to `critical', `bsod', `xflame', and `flow'.
795 * Added support for Kerberos 5 (via its Kerberos 4 compatibility
797 * Fixed a bad leak in `xteevee'.
798 * Updated `webcollage' to handle recent Altavista URL format changes.
799 * Removed xscreensaver-demo's `Ok' and `Cancel' buttons, since they
800 were confusing people: all changes are now instantanious.
801 * Made xscreensaver-demo install itself into the Gnome Control Center.
803 3.23 * Fixed some misplaced text fields in the Motif version of
804 xscreensaver-demo; fixed a crash in the Gtk version that would
805 happen if the programs list was empty.
806 * Fixed a recently-introduced bug in `pulsar'.
807 * Made `sierpinski3d' use solid tetrahedrons instead of points.
808 * Added `-trace' option to `xmatrix'.
809 * Added new hacks `xteevee' and `xspirograph'.
811 3.22 * Fixed some bugs in xscreensaver-demo.
812 * Rewrote the Motif version of xscreensaver-demo to match the new Gtk
814 * The Athena toolkit is no longer supported.
816 3.21 * Tweaked the xscreensaver-demo UI (Gtk only.)
817 * Fixed a few visual selection bugs. I think the proper GL visual
818 should be used with nVidia systems now.
819 * Made the Makefiles obey $install_prefix.
820 * Made the `xscreensaver.spec' file able to generate both GL and
821 non-GL packages simultaneously.
823 3.20 * Added new hacks `ripples' and `sierpinski3d'.
824 * Made `xscreensaver-command -exit' be silent when no screen saver was
825 running (instead of complaining.)
826 * Made `webcollage' and `vidwhacker' use `xloadimage' when available
827 (in addition to `xli' and `xv'.)
828 * Improved memory usage in `petri' and gave it a hard cap on how much
829 memory it can allocate.
830 * Added `-watch' option to `xscreensaver-command'.
831 * Made `xscreensaver-demo' come up with the most-recently-run hack
833 * Rewrote the Gtk version of `xscreensaver-demo'. It's a lot easier
835 * Extended the format of the programs list in the .xscreensaver file,
836 for the benefit of the new capabilities of `xscreensaver-demo'.
837 NOTE: you might want to delete your ~/.xscreensaver file and allow
838 it to be re-created! The old one should still work, but
839 xscreensaver-demo won't be as pretty.
841 3.19 * Fixed gcc dependencies in `bumps' and `ccurve'.
842 * New hack, `extrusion'.
843 * Some of the web sites that `webcollage' was using as its sources
844 changed formats; tweaked it to understand the current layouts.
845 * Added typeahead in the password dialog: if the screen is locked, and
846 you unlock it by typing a character, that key will be automatically
847 inserted in the password dialog (unless it is Return, Enter, Space,
848 or a non-printing key like Shift.)
849 * Made `xmatrix' take a `-small' option, since some folks with tiny
850 screens prefer a smaller font.
852 3.18 * New versions of `shadebobs', `lmorph', and `distort'.
853 * Added `ccurve', `blaster', and `bumps' hacks.
854 * Replaced `forest' hack with a rewritten version.
855 * Worked around a Xinerama server bug.
856 * Fixed a bug I introduced in 3.10 that caused some hacks to print out
857 superfluous warnings about not having gotten enough colors.
858 * Made `sproingies' obey the `-delay' option.
859 * Fixed a portability bug in `shadebobs'.
860 * Made `webcollage' and `vidwhacker' use `xli' in preference to `xv',
862 * Added a new source of images to `webcollage'.
863 * If running under KDE, xscreensaver will add itself to KDE's list of
864 screensavers (via xscreensaver.kss.)
865 * Improved detection of GL libraries.
866 * Made the password dialog include the date and time.
868 3.17 * New version of `webcollage' -- deals better with corrupted images,
869 and can use an http proxy.
870 * New hack, `xsublim' (run it in the background, rather than adding it
871 to the programs list.)
872 * The xscreensaver daemon was leaking a file descriptor each time you
873 edited your .xscreensaver file. Fixed.
875 3.16 * New version of `shadebobs'.
876 * Improved image selection in `webcollage', and sped it up slightly.
877 * Made configure find the right version of perl.
878 * Rewrote the CGI part of `webcollage'.
879 * `make clean' was deleting some things it shouldn't.
880 * Fixed a typo in the default programs list.
882 3.15 * Added `webcollage' and `shadebobs' hacks.
883 * Added a `-stdout' arg to `vidwhacker' so that it can be used in a
885 * Made `petri' use less memory.
887 3.14 * Various improvements to the Gtk port.
888 * Turned off PAM by default on Solaris, since PAM seems generally to
889 be misconfigured out-of-the-box.
890 * Made the `--without-gtk' configure option work.
891 * Made configure check the Gtk version number, since it requires 1.2.
892 * Fixed a bug in the code that attempted to prevent changes of screen
893 resolution while the screen is locked.
894 * Fixed a race condition in `xscreensaver-demo' that could cause an X
896 * Added `-transparent' option to `deluxe'.
897 * Added `petri' hack.
899 3.13 * Ported `xscreensaver-demo' to Gtk.
900 * Made it possible to build Motif, Gtk, and Athena versions of
901 `xscreensaver-demo' in the same directory without reconfiguring.
902 * Made `xscreensaver-demo' chase symlinks before writing the
903 .xscreensaver file, so that if .xscreensaver is itself a symlink,
904 the underlying file will be replaced instead.
905 * Some Makefile and configure tweaks for Solaris and FreeBSD.
906 * Made it possible to set the fire color in `xflame'.
907 * Made transparency work in TrueColor (for `goop' and `qix'.)
908 * Fixed a multi-head bug introduced by the virtual viewports stuff.
911 3.12 * Made it so that you can't scroll the screen while the lock dialog is
912 up (with XFree86 virtual viewports.)
913 * Fixed a bug in `flag' that caused bob's chin to get cut off after a
916 3.11 * Made `xjack' be black-on-white-ish, so that it looks less like a
917 computer screen and more like the typewritten paper it's supposed to
919 * New version of `pulsar'.
920 * Fixed Solaris compilation problem in `phosphor'.
921 * Made xscreensaver notice XFree86's virtual root window hack, so that
922 if the X server's root window is larger than the monitor's
923 displayable resolution, the screen saver will limit itself to the
924 area that actually appears on the screen.
925 * Made the xscreensaver daemon do a better job of picking the visual
926 class that should be used for GL programs. Less user intervention
927 should be needed now: you can use the logical visual name `GL'
928 instead of having to figure out by hand which one to use.
929 * Oops, the visual was defaulting to "best" instead of
930 "default", because the .xscreensaver file was not being
931 loaded quite early enough.
932 * Made configure figure out how to build icmp ping support into the
933 `sonar' hack automatically.
934 * Made warnings about not being able to read shadow passwords not be
935 printed if compiled with PAM support.
936 * Improved PAM startup diagnostics.
937 * Worked around the Solaris PAM bug that was causing crashes there, so
938 now PAM is turned on by default.
939 * Made configure detect the number of arguments that pam_strerror()
940 takes, since on Linux, this apparently changed between 2.0 and 2.2,
942 * Made the /proc/interrupts kludge look for "PS/2 Mouse" as well as
944 * Made xscreensaver notice when there has been a sudden large jump in
945 wall-clock time, and if so, lock right away, instead of waiting for
946 "lockTimeout" to expire first. (Laptops need this for safer
947 recovery from ``hibernation.'')
948 * Added `-throttle' option to `xscreensaver-command'.
950 3.10 * Added `phosphor', `xmatrix', and `pulsar' hacks.
951 * Fixed a bug in the color allocator that sometimes caused `starfish'
952 to fall back to monochrome.
953 * Reduced the amount of code that runs before root privileges are
954 disavowed: "normal" and "shadow" passwords now do some
955 initialization as root, but the PAM and Kerberos authorization
956 schemes will be initialized while running as "nobody". Supposedly
957 this closes a potential security hole when using Kerberos.
958 * Added some more sanity checking to configure.
960 3.09 * Added `compass', `squiral', `xflame', `wander', `spotlight', and
962 * Added some new modes to `decayscreen'.
963 * Made `deluxe' work in monochrome.
964 * Generalized usage of the Double-Buffer server extension in several
965 hacks (`compass', `deluxe', `interference', `kumppa', and `moire2'.)
966 * Fixed another visual-depth problem in `rd-bomb'.
967 * The screen saver will now defer blanking if neither the keyboard nor
968 the mouse could be grabbed. Instead, it will just try again in a
969 few minutes. This fixes a bad interaction between xscreensaver and
970 programs like VMware that hold the mouse and keyboard grabbed for a
972 * Added a new erase mode (expanding spiral.)
974 3.08 * Fixed some bugs in my port of `t3d'.
975 * Added `penetrate' and `deluxe' hacks.
976 * When linking against Motif 2.x, also link against XPM.
977 * Added support for using /proc/interrupts for idle detection on
978 Linux. Now xscreensaver shouldn't kick in when the user is active
979 on a non-X virtual console.
980 * Upgraded to autoconf 2.13.
982 3.07 * Configure tweaks (sometimes -lXmu wasn't getting linked in properly;
983 check for _Xsetlocale in -lXintl.)
984 * Portability fixes for sonar.c.
985 * Fixed a compilation problem when you have GL but don't have XPM.
986 * Made configure notice when MesaGL requires -lpthread.
987 * Made `flame' ignore SIGFPE (not sure if this is the right fix; it
988 seems only to be needed on FreeBSD.)
989 * Kludged `rd-bomb' work on visuals that are of depth 24 but that *do
990 not* support pixmaps of depth 32.
991 * Fixed `halo' to work properly in TrueColor.
992 * Changed `xscreensaver.spec' to install the hacks in
993 /usr/X11R6/lib/xscreensaver/ by default, since that's where recent
994 Red Hat distributions put them.
996 * Updated versions of `crystal', `hopalong', and `flow' from
998 * Imported `demon' and `loop' modes from xlockmore.
1000 3.06 * Oops, the "default-n" visual descriptor was broken; it was always
1001 installing a colormap if the `installColormap' preference was set,
1002 meaning that `xearth', `xv' and friends were using the wrong colors
1004 * Turned off HAVE_PING in `sonar', since it compiles on some Linux
1005 systems, but not others of similar vintage...
1007 3.05 * Fixed an off-by-1 in `distort'.
1008 * Added `sonar' hack.
1009 * New version of `glplanet' (with stars.)
1010 * Made all hacks exit when you type `q' or `ESC' at them, and made
1011 them obey the WM_DELETE_WINDOW ClientMessage.
1012 * Fixed a nonfatal buffer overrun in lament (note: lament still
1013 doesn't work with MesaGL 3.0: it dies in
1014 lambda_textured_triangle1(), which is Mesa's bug, not mine.)
1016 3.04 * Added an `xscreensaver.spec' file, to make it easier for other folks
1018 * Made the password code work on HPUX in the situation where:
1019 ``enhanced security'' is available; but not used; but the user typed
1020 a password more than 8 characters long anyway. FTSOHPUX.
1022 3.03 * Made locking work when passwd aging is enabled.
1023 * Added support for PAM (Pluggable Authentication Modules.) It is
1024 still turned off by default, though, since it doesn't seem to work
1025 on Solaris 2.6, and has been behaving erratically on Red Hat 5.1.
1026 * Made each possible authentication method be tried in turn until one
1027 succeeds; this means that Kerberos is being used, we will first
1028 check Kerberos, and if that fails, will then consult the local
1029 password file. Likewise with PAM.
1030 * Save and restore the bits under the passwd dialog, to avoid leaving
1031 a black rectangle behind when unlocking is cancelled.
1033 3.02 * Not everyone has sys/select.h, sigh...
1035 3.01 * Some fixes to `reflect'.
1037 * Made it log unsuccessful attempts to unlock the screen to syslog.
1038 * Fixed a bug where `xscreensaver-demo' could be seeing a different
1039 programs list than `xscreensaver' did.
1041 3.00 * The xscreensaver daemon no longer links against Motif or Athena:
1042 demo-mode and the preferences panel are no longer built in to the
1043 daemon, but are now handled by an external program,
1044 `xscreensaver-demo'. (I decided that this, along with the recent
1045 addition of the `.xscreensaver' config file, justified bumping the
1046 version number to 3.00, since this is a fairly major architectural
1048 * Lines in the `*programs' resource may now begin with the character
1049 "-", meaning "don't run this hack." In this way, it's possible to
1050 disable a hack without throwing away the information about it
1051 (making it easier to change your mind later.) Eventually the
1052 preferences/demo mode GUI should represent this as a checkbox or
1054 * Fixed a short race condition where it was possible for xscreensaver
1055 to die with a BadWindow error if it was blanking the screen just as
1056 another window was being deleted.
1057 * Made it possible to disable specific modes in `bsod'.
1059 2.34 * Fixed a bug that was making `pipes' generate way too many valves.
1060 Made the viewpoint in `pipes' be selected randomly instead of always
1062 * Fixed a bug in the XSHM code, in the case where the server supports
1063 the XSHM extension but is not the same machine as the client.
1064 * Made `rd-bomb' default to taking up the whole screen.
1065 * Made it not try to do fading/unfading if no PseudoColor visuals
1067 * Initial attempt at supporting VT-locking (doesn't work yet.)
1068 * Eliminated the `captureStdout' resource; now `captureStderr'
1069 controls both streams.
1070 * Added `-capture-stderr' and `-no-capture-stderr' command-line
1072 * Added `glplanet' hack.
1073 * When a hack is selected with `xscreensaver-command -select', that
1074 hack will be used until further notice (until the saver turns off,
1075 or another activation command is issued.)
1077 2.33 * Made `xscreensaver-command' print error messages: the xscreensaver
1078 daemon now responds to ClientMessage events by writing a response
1079 message on a window property, instead of just writing to its stderr.
1080 * Made the ~/.xscreensaver file be automatically reloaded when the
1082 * The password dialog and splash screen no longer depend on Motif or
1083 Athena. This should clear up a number of focus problems, and is the
1084 first step on the path toward moving all of the
1085 Motif/Athena/whatever code out of the xscreensaver daemon, and into
1087 * Don't complain about LessTif 0.86 any more, since the new password
1088 dialog makes that problem go away.
1089 * Configure tweaks for Irix 6.5, SunOS 5.something.
1090 * New `-reflect' option to `distort'.
1092 2.32 * Added reading and writing of a ~/.xscreensaver file, so that the
1093 Preferences panel can save its settings.
1094 * New version of `rubik'.
1095 * Added `-select N' argument to `xscreensaver-command'.
1096 * Oops, left out some of the `bubbles3d' files...
1098 2.31 * The cursor was invisible in the password dialog. Fixed.
1099 * Made configure warn against MesaGL 2.6.
1100 * Fixed X error at startup when using non-default visual.
1101 * New version of `crystal', `ant', and `atlantis' from xlockmore.
1102 * New hack, `bubble3d'.
1103 * Added some new modes to `bsod'.
1105 2.30 * Changed the order in which -lSM and -lICE are linked to be after
1106 Motif instead of before (Lesstif on Irix needs this.)
1108 2.29 * Work around a bash bug in configure.
1109 * Tweaked HPUX paths again. FTSOHPUX.
1110 * Made configure recommend against LessTif 0.86, due to a bug in that
1111 version that causes a security hole in the screen locking code.
1112 LessTif 0.87 will fix it.
1113 * Made all of the `--with' options to `configure' accept a directory
1114 option as well (so that --with-motif=/FOO will add -I/FOO/include
1115 -L/FOO/lib). I believe this is the Configure Party Line of how do
1117 * Fixed a bug where the mouse was left un-grabbed after the first time
1118 the graphics hack was changed (simplified all of the mouse-grabbing
1120 * Maybe possibly perhaps made `vidwhacker' really not leave stray xv
1121 windows around. This time for sure.
1122 * Added a new erase mode (random dots fizzling out.)
1123 * Added `-prefs' argument to `xscreensaver-command', that brings up
1124 the Preferences dialog directly (it seems that nobody ever noticed
1125 the `Preferences' button on the Demo Mode dialog, maybe this will
1127 * Added a splash screen. Turn it off with *splash:false.
1129 2.28 * Better macsbug text in `bsod'.
1130 * New version of `distort' with many new modes.
1131 * Plugged a leak in `coral'.
1132 * Tweaked configure for HPUX.
1133 * Removed some compiler warnings.
1134 * More consistent usage of stderr versus stdout.
1135 * More diagnostics should an X error occur.
1136 * Fixed a possible crash in SGI-specific unfading code.
1138 2.27 * Improved version of `distort'.
1139 * Made `lament' compile against OpenGL 1.0 (though it still requires
1140 1.1 to work properly.)
1141 * Updated my email address and home page.
1143 2.25 * Improved motion in `rd-bomb'.
1144 * Added XSHM (shared memory extension) support to the `distort',
1145 `interference', `moire', `rd-bomb', and `swirl' hacks, which speeds
1147 * Added `lament' hack.
1149 2.24 * Tweaked the order of the -L options again.
1150 * Cleaned up configure's `--help' message.
1151 * Added `kumppa' hack.
1152 * Smarter maze-solving algorithm in `maze'.
1153 * Took `xlyap' out of the default list of hacks, since it's just
1154 incredibly buggy (and slow.) Maybe someday someone will fix it...
1155 * Added `distort' hack, but didn't add it to the default list (yet)
1156 because it's still too slow.
1157 * Made the Athena demo dialog look more like the Motif version; it has
1158 a text-entry field now, too.
1159 * Made the Athena password dialog echo asterisks, like Motif does,
1160 instead of using a flyspeck font.
1161 * Some random configure tweaks.
1162 * Added a `timestamp' resource that makes the `-verbose' messages
1163 include the time at which they were printed.
1165 2.23 * The fix for SGI's ``scheme'' nonsense broke things, and let the
1166 user's "*background" resource show through. Fixed it in a different
1169 2.22 * Added support for the DPMS server extension (Display Power
1171 * Made configure advertize the `--enable-subdir' option a little more,
1172 since that seemed to cause some people stress. Also, made that
1173 directory be built into the xscreensaver executable, as a hardcoded
1174 prefix to $PATH. (Might help, shouldn't hurt.)
1175 * Made configure prefer the two-arg gettimeofday to the one-arg
1176 version, since AIX doesn't have any prototypes.
1177 * Made it work with Xaw3d (the 3D Athena library.)
1178 * Made `make install' create directories as necessary.
1179 * New version of lmorph from Sverre.
1180 * Added `crystal' and `discreet' hacks from xlockmore.
1181 * Added a new mode to `bsod'.
1183 2.21 * Made `xscreensaver-command -time' use different words. (It now
1184 describes the two states as "screen blanked since..." and "screen
1185 non-blanked since..." instead of "active since..." and "inactive
1186 since..." which a lot of people interpreted as meaning the opposite
1187 of what was intended.)
1188 * Improved some error messages, in the hopes of making the distinction
1189 between the xscreensaver and xscreensaver-command programs more
1191 * Rewrote (and reorganized) parts of the xscreensaver and
1192 xscreensaver-command manual pages.
1193 * Renamed xscreensaver's `-lock' command-line option to be
1194 `-lock-mode', to avoid confusion with the `-lock' option to
1195 xscreensaver-command, which does a totally different thing.
1196 * Removed xscreensaver's `-demo' command-line option for a similar
1197 reason; use `xscreensaver-command -demo' instead.
1198 * Disabled SGI's ``scheme'' nonsense in a better way than
1199 fully-qualifying the background colors in every single hack.
1200 * Fixed some other minor cosmetic problems when *sgiMode is turned on.
1201 * Fixed an X error in `bsod -root' (how ironic...)
1203 2.20 * Fixed a bug that caused the mouse to sometimes not be grabbed
1204 properly (meaning the window manager menu could pop up over the
1206 * Fixed a bug that made the stderr output sometimes get printed twice.
1207 * Fixed a bug that made the demo-mode scrollbar move too fast.
1208 * Protected against a possible buffer overflow.
1209 * Made `vidwhacker' not leave stray xv windows around.
1210 * New version of `ant' so that Bagley doesn't calve.
1211 * Make configure on AIX get XShm from the right library.
1213 2.19 * One file was missing from the tar file.
1215 2.18 * Oops, atlantis wasn't being built by default.
1216 * Added `epicycle' hack.
1217 * Added `interference' hack.
1218 * Added `truchet' hack.
1219 * Added `bsod' hack.
1220 * Added some new modes to `vidwhacker'.
1222 2.17 * Added a -window-id argument to most hacks, so that they can draw on
1223 arbitrary externally-provided windows.
1224 * Synched with xlockmore 4.11a01.
1225 * Added `flow' hack.
1226 * Added `atlantis' GL hack.
1227 * Renamed `puzzle' hack to `jigsaw', since xlock already had a
1228 different mode called `puzzle'.
1229 * Made it self-configure properly when Motif 2.1.0 is being used
1230 (requires -lXp now, sigh...)
1232 2.16 * Made `flag' able to do XPM images.
1233 * New look for the xscreensaver logo (`xroger').
1234 * Fixed compilation error on Suns with adjunct passwords.
1235 * Got multi-architecture builds working again.
1236 * Some configure tweaks for building on HPUX and Solaris.
1237 * Fixed bug in decayscreen.
1238 * Fixed typo in passwd.c.
1239 * Made `cynosure' not die when colormap is full.
1241 2.15 * Added `cynosure' hack.
1242 * Added `moire2' hack.
1243 * Tweaked `erase.c' some more.
1244 * Made unfading a bit smoother.
1245 * Added `vidwhacker' hack (not installed by default.)
1246 * Added `stairs' hack.
1247 * Split `escher' into `cage' and `moebius', as per xlockmore.
1248 * Changed subprocess handling to use sigaction() instead of signal()
1249 if it's available (this is necessary for SCO but should work fine on
1251 * Various other tweaks.
1253 2.14 * Better fix for the Motif drag-and-die lossage.
1254 * Put in some kludges to work around a LessTif bug.
1255 * XScreenSaver is known to work with LessTif 0.82 now.
1256 * Made fading work on high-end SGI video hardware.
1257 * Fixed another SGI-specific bug in screen grabbing; will the madness
1259 * Fixed another crash in `xlyap'.
1261 2.13 * Made `decayscreen' do directions other than down.
1262 * Improved `puzzle'.
1263 * Fixed a crash in `xlyap'.
1264 * Added CDE info to the man page, removed `cde.txt'.
1265 * Configure tweaks for Zippy.
1266 * Turned off the signal handling in `bubbles' because it was sometimes
1268 * Added `hacks/xscreensaver-sgigl.c' to make it possible to run SGI's
1269 ElectroPaint hack (/usr/demos/bin/ep) with xscreensaver. Finally!
1270 * Fixed a buffer overrun in the locking code that some wily, malicious
1271 cracker must have slipped in.
1272 * Disabled Motif drag-and-drool in the dialog box buttons, since it's
1273 broken in some old versions of Motif.
1275 2.12 * Added `README.debugging'.
1276 * Added `puzzle' hack.
1277 * Added `xlyap' hack.
1278 * Added `default-n' as a visual name, so that one can have -install on
1279 by default, but turn it off for certain poorly-behaved hacks (like
1281 * Added support for grabbing frames of external video (on SGI) to the
1282 screen-grabbing hacks (decayscreen, slidescreen, slip, blitspin, and
1284 * Improved look of tiles in `slidescreen'; fixed its color allocation
1287 2.11 * Tweaked `blitspin', added it to the default list.
1288 * Added `lissie', `mountain', `triangle', `worm', `rotor', and `ant'
1290 * Updated `sierpinski', `galaxy', and `lisa'.
1291 * Thickened the lines in `braid' and `lmorph'.
1292 * Updated VMS makefiles.
1293 * Renamed `fract' to `vines'.
1294 * Added `xjack' hack.
1295 * Made a few more hacks use erase.c, and added a few more wipe styles.
1296 * Fixed compilation problem with Sun's version of OpenGL.
1297 * Added ability to use sigaction() instead of signal()
1298 to work around a SCO kernel bug.
1300 2.10 * Fixed colormap bugs in `rd-bomb'; sped up `coral'.
1301 * Configure tweaks for *BSD.
1303 2.08 * New hacks `rd-bomb' and `coral'.
1304 * New version of `maze' with some new algorithms.
1305 * New colorized version of `rocks'.
1306 * Fixed a bug in qix on 64-bit machines.
1307 * Fixed a bug in the -time option.
1308 * Fixed a bug in configure related to LessTif.
1310 2.07 * Minor header tweaks in windows.c and flag.c.
1311 * Made multi-architecture ($VPATH) builds work properly.

1331 * Various configure tweaks.
1333 2.01 * Added `goop' and `starfish' hacks.
1334 * Added colomap cycling to `halo'.
1335 * Made `attraction' use the new colormap allocator.
1336 * Added better $PATH diagnostics.
1337 * There was a bug in frand! Color selection should be much improved
1340 2.00 * Converted to use `configure' instead of `imake'.
1341 * ANSI C is now required.
1342 * Added Kerberos locking support, from Nat Lanza.
1343 * Made the stderr text use overlay planes, if possible.
1344 * Reworked the xlockmore compatibility stuff again.
1345 * Added `gears', `superquadrics', `escher', `pipes', and `sproingies'
1346 hacks (depend on OpenGL.)
1348 1.34 * Fixed some bugs, made fading be a little smoother.
1350 1.33 * Made it work with multi-headed displays.
1351 * Generalized sub-process management (Unix sucks!)
1352 * Added interactive mouse frobbing to Julia.
1353 * Added (untested) support for HPUX shadow passwords.
1354 * Made normal non-shadow passwords be checked if the shadow passwords
1355 aren't accessible for some reason.
1357 1.32 * Removed *colorPrograms and *monoPrograms resources: made it possible
1358 to specify the desired visual on a per-hack basis.
1359 * Cleaned up / restructured the driver: no more globals.
1360 * Made the Motif and Athena dialogs share more code.
1361 * Probably fixed some Athena colormap-installation bugs.
1362 * Fixed screen grabbing (cmap) on SGI 12-bit PseudoColor.
1363 * Fixed divide-by-zero in bright random colormaps.
1364 * Added an improved version of xlock's `flag' hack.
1365 * Made unfading work better, and not flicker on SGIs.
1366 * Added `sphere', `forest', `lisa' hacks from xlockmore.
1367 * Added (untested) support for SunOS Adjunct passwords.
1369 1.31 * Improved colors and colormap cycling of many hacks.

1371 * Made `blitspin' able to grab an image off the screen.
1372 * Ported `swirl' and `bouboule' hacks from xlockmore.
1373 * Made the driver more careful about not leaving bits on the screen,
1374 or allowing other windows to raise themselves: it now re-blanks the
1375 screen every so often.
1376 * Added `-time' option to `xscreensaver-command'.
1377 * Improved SGI screen-grabbing some more: now it can grab TrueColor
1378 screens into PseudoColor windows and have the colors still come out
1381 1.30 * Made `slidescreen' and `decayscreen' work better on SGIs when
1382 windows of different visuals are present, by using the
1383 XReadDisplay() extension to get a true 24-bit image out of the frame
1385 * Made `noseguy' be in color, if compiled with XPM.
1386 * Ported `braid', `drift', `fract', `galaxy', `grav', `ifs', `julia',
1387 `laser', `lightning', `penrose', `sierpinski', `slip', `spiral', and
1388 `strange' hacks from xlockmore.
1389 * Merged `hopalong' hack with a more recent version.
1392 1.28 * Added `deco', `moire', and `kaleidescope' hacks.

1394 * Made `blitspin' and `bubbles' work in TrueColor.
1395 * Fixed a stupid bug I introduced in `imsmap'.
1396 * Added `poly' and `gravity' options to `qix'.
1398 1.27 * Added support for SGI SCREEN_SAVER extension.
1399 * Made `fade' and `unfade' work on 8-bit SGIs.
1400 * Made the dialog boxes more Motify.
1401 * Added `bubbles' hack.

1406 * Added ramp-mode to halo.
1407 * Added a new RNG, which is faster and more portable than using the
1409 * Made locking work on SCO.
1410 * Various other minor tweaks that I don't remember.
1412 1.25 * Made it capture the stdout/stderr of its subprocesses and present
1413 them on the screensaver window itself.
1414 * Made demo mode work correctly with non-default visuals and color
1415 maps, instead of always using the defaults.
1416 * Added -visual argument to all included screenhacks.
1417 * Support for the R6 MIT-SCREEN-SAVER server extension.
1418 * Made the demo mode list scroll properly.
1419 * Added `pedal' hack.
1421 1.24 * Fixed some private-colormap oddities in slidescreen, decayscreen,
1422 and xroger. Fixed apparent conservation- of-mass problem in pyro;
1423 made the shrapnel round.
1425 1.23 * Minor tweaks for IRIX5; fixed locking race condition.
1427 1.22 * Minor tweaks for X11R6.
1428 * Fixes for non-default visuals.
1430 1.21 * Fixed bug in color blitspin; added default image.
1431 * Added diagnostics to noseguy. Fixed off-by-one error in flame.
1432 * Added some missing casts.
1434 1.19 * Added `flame' hack.
1435 * Fixed a minor Motif dialog text field bug.
1436 * Fixed yet another XPointer-not-defined-in-R4 bug.
1438 1.18 * Added support for shadow password files.
1439 * Fixed some Motif-related locking bugs.
1440 * Added diagnostics when locking is disabled.
1441 * Made blitspin able to use the XPM library.
1442 * Added `decayscreen' hack.
1444 1.17 * Added `halo' hack.
1446 1.16 * Portability fixes.
1448 1.15 * Broke the driver up into more source files.
1449 * Moved the hacks into their own directory.
1450 * Made all `time' parameters accept the 00:00:00 syntax, so that even
1451 the parameters which are normally read as minutes can be specified
1453 * Added colormap cycling to `imsmap'.
1454 * Made hyper work with K&R compilers.
1456 1.14 * Added `orbit' option to `attraction' hack.
1457 * Added `lock-timeout' option.

1467 the screen is not blanked.
1468 * Fixed a BadDrawable error in non-XIdle mode.
1469 * Added `blitspin' and `imsmap'.
1471 1.01 * Current list of included hacks is now: qix, helix, rorschach,
1472 attraction, greynetic, rocks, pyro, hopalong, and noseguy.
