7 iOS and Android
9 By Jamie Zawinski
10 and many others
16 This is the XScreenSaver source code distribution. It is strongly recommended
17 that you install a binary release rather than trying to compile it yourself.
18 Executables are available for almost all platforms, including macOS, iOS, and
19 Android. See the XScreenSaver web site for details.
23 To compile for a Unix system with X11:
26 ./configure --help
28 ./configure --prefix=/usr
30 sudo make install
31 make clean
33 xscreensaver &
36 There are many compilation dependencies. The configure script will
37 tell you what is missing. At the least, you will need development
38 versions of these libraries:
40 perl pkg-config gettext intltool libx11 libxext libxi libxt
41 libxft libxinerama libxrandr libxxf86vm libgl libglu libgle
42 libgtk2 gdk-pixbuf-2.0 gdk-pixbuf-xlib-2.0 libxml2 libpam
43 dbus libsystemd elogind
45 BSD systems might need gmake instead of make.
49 To compile for macOS or iOS:
52 See OSX/README. Use the included Xcode project.
56 To compile for Android:
59 See android/README.

528 * More options in `flipflop'.
529 * Minor updates to `topblock'.
530 * Various other minor fixes.
532 5.00 * Ported to macOS! (10.4.0 or newer)
533 * API change: instead of providing a single screenhack() function that
534 does not return, screen savers using the screenhack.h framework must
535 now provide "init" and "draw one frame" functions instead. All
536 bundled savers have been updated; third-party patches will need
538 * All image-loading happens asynchronously.
539 * xscreensaver-getimage-file caches the contents of the image
540 directory for a few hours, so consecutive runs won't have to re-list
541 the whole directory tree.
542 * New hacks, `topblock' and `glschool'.
543 * Removed `xteevee' (superceded by `xanalogtv').
544 * Added variable-sized puzzle pieces to `jigsaw'.
545 * Changes to the defaults and command-line options of many hacks to
546 make the .xml files more consistent.
547 * Reap zombies in `glslideshow' and `carousel'.
548 * `sonar' works without setuid on macOS (dgram icmp).
549 * `xmatrix -mode pipe' displays the text of a subprocess.
550 * `endgame' has higher resolution chess-piece models.
551 * `webcollage' takes a -directory option to get images from a local
553 * The RPM spec file no longer auto-restarts xscreensaver when a new
554 version is installed. Restart it manually.
556 4.24 * New versions of `cube21', `glsnake', `celtic'.
557 * Backed out a DPMS-related patch that cause desktop flickering with
558 some X servers.
559 * Fixed startup crash in getgroups() when running setuid.
560 * Default to not displaying stderr on the saver window.
561 * Fixed bad free() in "Documentation" button.
562 * Don't try to run hacks that aren't installed.
563 * Minor fixes to various XML config files and man pages.
565 4.23 * New hacks, `glhanoi', `cube21', `timetunnel', `juggler3d', and
567 * New versions of `tangram', `webcollage', `hypertorus', `polytopes',
568 and `ripples'.
569 * `sonar' is now quiet about unresolvable hosts.
570 * Minor corrections to BASIC code in `apple2'.
571 * xscreensaver-demo now provides an RPM clue when none of the hacks
572 seem to be installed.
573 * Don't install `ant' by default, since there is some Java tool of
574 that name, which was causing confusion. And also it's boring.
575 * Made screen grabbing work again on macOS 10.4.2.
576 * No longer prints bogus warnings about ClientMessages intended for
577 the window manager.
578 * Ignore unprintable characters in passwd entry field.
579 * Fixed yet another cross-host-display image-loading endian problem.
580 * `xscreensaver-command -watch' and `-time' now work on 64-bit
583 4.22 * Fixed a bug in the new mouse-motion code that caused the screen to
584 never blank on multi-head non-Xinerama systems. Oops.
585 * New hacks, `interaggregate', `antmaze', `tangram', and `crackberg'.
586 * Minor tweaks to `fiberlamp', `ifs', `slidescreen', `zoom', `sonar',
587 `fireworkx', `whirlwindwarp', `bubble3d', and `rd-bomb'.
588 * Added motion blur to `blinkbox'.
589 * `bsod' now includes Longhorn's "RSOD", and OS/2.
590 * Fixed `-wireframe' usage in most hacks and man pages.
592 4.21 * New hack: `fliptext'.
593 * Changed default configure installation directories: /usr/bin/ for
594 xscreensaver, etc.; /usr/libexec/xscreensaver/ for hacks;
595 /usr/share/xscreensaver/config/ for xml files.
596 * All the text-manipulating screen savers can have their text source
597 configured via `xscreensaver-demo' now.
598 * xscreensaver.spec now builds three RPMs: base (no hacks); extras (2d
599 hacks); and gl-extras.
600 * Added `-program' and `-front' option to `gltext'.
601 * Added `-shells' to `molecule'.
602 * Fixed text-alpha glitch in `carousel'.
603 * New `pacman': the ghosts can be killed now.
604 * Fixed a bug in screen-grabbing GL hacks where images would be tiled
605 instead of scaled on machines that can't do large textures.
606 * `webcollage' can hit Flickr now.
607 * New (rewritten) implementation of `ifs'.
608 * The unlock dialog can be made to have a "New Login" button that will
609 run `gdmflexiserver'. Experimental!
610 * Fixed non-ASCII display bug in `starwars'.
611 * Configure finds a default for imageDirectory.
612 * `xscreensaver-command -lock' now works even if in "screensaver
613 disabled" mode.
614 * If a bad password is typed while CapsLock is on, the unlock dialog
615 says "CapsLock?" instead of "Sorry".
616 * Mouse motion only counts as activity if the mouse moved more than 10
617 pixels (so the screen won't unblank every time you bump your desk.)
618 * New mode option "random-same": if you have multiple monitors, this
619 will run the *same* randomly chosen hack on each screen, instead of
620 different ones on each.
622 4.20 * New hacks, `fiberlamp', `boing', `boxfit', and `carousel'.
623 * Rewrote `glslideshow' again: should be faster now.
624 * Sped up loading of images in GL programs.
625 * `starwars' uses texture-mapped fonts now.
626 * New `bsod' modes: tru64, hppa, and nvidia.
627 * Updates to `webcollage', `juggle', `pinion', `fireworkx', `sonar',
628 `extrusion', `substrate', and `pong'.
630 4.19 * New hacks, `substrate', `intermomentary', `fireworkx', and `pinion'.
631 * New version of `flow'.
632 * Made /proc/interrupts work again on Linux 2.6.
633 * Made `analogtv' not hog the CPU.
634 * Made analogtv-based hacks work properly on PPC/ARM.
635 * Fixed a bad memory leak in `piecewise'.
636 * Minor updates to `sonar', `molecule', `glmatrix', `galaxy', and
638 * Removed support for GTK 1.x (everyone uses 2.x now.)
640 4.18 * Oops, pay no attention to the man behind the curtain.
642 4.17 * New hacks, `anemotaxis' and `memscroller'.
643 * Fixed a bad bug that caused `vidwhacker' to never die.
644 * Fixed normals and lighting in `polyhedra'.
645 * Don't reuse the window when changing hacks (to work around bugs in
646 some GL implementations.)
647 * Made `xscreensaver-getimage-file' skip thumbnail-sized images.
648 * Fixed endian problem in `barcode' on non-x86.
649 * Updates to `webcollage', `apple2', `fuzzyflakes', `atunnel', and
651 * Timing tweaks to `bubble3d', `bouncingcow', `engine', `gltext',
652 `lavalite', `molecule', `spotlight', `sballs', `boxed', `blinkbox',
653 and `circuit'.
654 * Configure updates for Fedora core 2 / xorg 6.7.0.
655 * Compile without warnings under gcc 3.3.3.
656 * I give up: don't blank or lock the screen if we can't get a keyboard
657 grab. In that case, both choices are bad.
659 4.16 * New hacks, `polyhedra', `fuzzyflakes', `antinspect', and
661 * Minor updates to `webcollage', `bsod', `endgame', `antspotlight',
662 `xmatrix', and `glmatrix'.
663 * Added support for the RANDR (Resize and Rotate) extension to detect
664 when the size of the desktop has been changed while xscreensaver is
665 already running.
666 * Possibly-futile attempt to work around "rdesktop" focus/grab idiocy.
667 * Made `xscreensaver-getimage -file' still work even if imageDirectory
668 is unset.
669 * Convert Latin1 to ASCII in `starwars' and `phosphor' (since the GLUT
670 font only has ASCII glyphs.)
671 * Fixed randomization in `noof'.
672 * Added "GetViewPortIsFullOfLies" preference to work around
673 longstanding XFree86 bug #421.
674 * Made `sonar' subnet pinging work properly on bigendian machines
675 (e.g., PPC.)
677 4.15 * New hacks, `wormhole', `mismunch', `noof', and `pacman'.
678 * `phosphor' and `apple2' include vt100 emulators now: this means you
679 can do "phosphor -program top", or can use either program as an
680 xterm replacement: "apple2 -text -fast -program 'xemacs -nw'".
681 * `analogtv' (and related) fill the screen better.
682 * The '-gradient' option works in `atlantis' now.
683 * Minor updates to `blinkbox', `queens', `endgame', `glmatrix',
684 `mirrorblob', `blocktube', and `molecule'.
685 * Integrated SuSE's "external passwd helper" support.
686 * Marginally better /tmp handling in various programs.
687 * Updated config defaults for xplanet 1.0.3.
688 * Portability fixes.
690 4.14 * New hacks, `fontglide', `apple2', `xanalogtv', `pong',
691 `gleidescope', `mirrorblob', and `blinkbox'.
692 * New version of `glsnake' (with many more models.)
693 * Another Windows crash in `bsod'; also HVX/GCOS6/TPS6.
694 * New version of `endgame'.
695 * Screen grabbing works on macOS.
696 * Various minor fixes.
698 4.13 * On Xinerama systems, xscreensaver now runs one hack on each monitor
699 (just like in "real" multi-head mode) instead of running one hack
700 stretching across all the screens. Note that for this to work with
701 any 3rd party screensavers, they must update their "vroot.h" file.
702 * `webcollage' and `vidwhacker' display images using
703 `xscreensaver-getimage' now.
704 * Added `ljlatest' script for use with `starwars' and `phosphor'.
706 4.12 * New GL hacks, `flipflop', `antspotlight', and `polytopes'.
707 * Added VMS to `bsod'.
708 * Compile without warnings in `gcc -pedantic'.
709 * Updates to `webcollage' and `queens'.
710 * Fixed a bug that could cause PAM to hang.
712 4.11 * New hacks, `hypertorus', `cubestorm', `glknots', `blocktube', and
714 * Updates to `cloudlife', `engine', `xmatrix', and `sonar'.
715 * Rewrote `glslideshow': it should work on somewhat wimpier video
716 cards now.
717 * Various portability tweaks.
719 4.10 * New hacks, `cloudlife' and `klein'.
720 * Added Apple ][+, HPUX, and OS/390 sessions to `bsod'.
721 * Added some Matrix Reloaded text to `xmatrix'.
722 * Updates to `webcollage', `eruption', `jigglypuff', `metaballs', and
724 * Completely ignore the `memoryLimit' setting now, since it was still
725 causing people GL grief.
726 * Various minor fixes.
728 4.09 * New hacks, `flyingtoasters', `bouncingcow', `jigglypuff', and
730 * More models in `engine'.
731 * Rewrote `xscreensaver-getimage' to remove reliance on external image
732 loaders (xv, chbg, xloadimage, etc.) and to reduce flicker when
733 loading files.
734 * Made `gflux' and `flipscreen3d' be mouse-spinnable.
736 4.08 * New hacks, `atunnels' and `piecewise'.
737 * Physics improvement in `fluidballs'.
738 * Various fixes for XDarwin systems (X11 on macOS.)
739 * Added -clock option to `barcode'.
740 * Minor fixes to `endgame', `flurry', `flipscreen3d', and `gflux'.
743 4.07 * New hacks, `flurry', `metaballs', `eruption', `popsquares', and
745 * Minor updates to `maze' for high density mazes.
746 * Added double buffering to `fluidballs' and `whirlygig'.
747 * Bug fixes for running xscreensaver to a remote XFree86 display
748 (which nobody would ever do...)
749 * Updated `webcollage' (faster Alta Vista searching.)
750 * Updated `glplanet' so the sun sets in the west.
751 * Updated `sproingies' with smooth, unsegmented surfaces.
752 * Fixed Perl version-sensitivity in `xscreensaver-getimage-file'.
753 * Fixed GTK2 scrolling bug in `xscreensaver-demo'.
755 4.06 * New hack, `glblur' (disabled by default, since it requires fast
756 OpenGL texture support.)
757 * New hack, `halftone'.
758 * Updates to `endgame', `queens', `bumps', `glplanet', `engine', and
760 * New version of `menger' that uses far fewer polygons.
761 * Fixed minor bug in `critical' that could cause some bogus X servers
762 to crash.
763 * Better labels in `molecule': the labels now appear to be attached to
764 the atoms, instead of floating in front of the whole scene.
765 * Fixed bug that could rarely cause GL hacks to fail to double-buffer
766 (causing intermittent flickering.)
767 * Fixed a relative-URL-parsing bug in `webcollage'.
768 * Fixed a bug that (sometimes) caused the window manager close box to
769 kill `xscreensaver-demo' with a crash instead of a graceful exit.
770 * Updated xscreensaver.pam to the Red Hat 7.3 way.
771 * More Gnome2-related configure crap.
772 * Updated to latest `config.guess' and `config.sub'.
773 * Fixed occasional core dump in `distort'.
774 * Added a Linux fsck failure and kernel panic to `bsod'.
775 * Added macOS kernel panic to `bsod'.
776 * Fixed a bug in `bsod' (all bsod bugs are ironic.)
777 * Fixed a bug that caused `xscreensaver-gl-helper' to print a nonsense
778 visual ID with some versions of `printf': this could cause GL
779 programs to display incorrectly (e.g., flickery.)
781 4.05 * More `configure' tweaks to try and get things working on systems
782 that both Gtk 1.x and 2.x installed.
783 * New hack, `endgame'.
784 * Minor updates to `gltext'.
786 4.04 * Support for GTK 2.x / GNOME 2.x.
787 * The `configure' script will now use `pkg-config' if you have it, in
788 preference to `gtk-config', etc.
789 * New hacks, `lavalite', `queens', and `anemone'.
790 * Minor updates to `spheremonics', `gltext', `xmatrix'.
791 * You can use the mouse to manually spin most of the GL hacks now
792 (when they are displaying in a window.)
793 * Fixed a bug in `webcollage' (due to recent Alta Vista url changes)
794 that was causing it to try and load incorrect image URLs.
795 * Made `xscreensaver-getimage' use gdk_pixbuf if it is available: this
796 means that those hacks that load images will no longer rely on `xv',
797 `xloadimage', etc. This will close a race condition that could
798 sometimes cause your desktop background to be changed; and also
799 makes it possible for those programs to operate on image files when
800 running in windowed mode.
801 * `webcollage' can now be used in conjunction with `driftnet' to
802 display images snooped from your local ethernet instead of obtained
803 from search engines.
804 * Added man pages for all the hacks that didn't have them.
806 4.03 * New hack, `spheremonics'.
807 * Minor updates to `webcollage', `cage', `moebius', `morph3d',
808 `boxed', `circuit', and `helix'.
809 * `pulsar' and `extrusion' can now load texture JPEGs.
810 * `rubik' now does non-square cubes.
811 * `fluidballs' now does various sizes of balls.
812 * `menger' and `sierpinski3d' now also show polygon counts in -fps
814 * `molecule' displays real subscripts in the formulae.
815 * GTK internationalization/localization support.
816 * Better detection of the various versions of libxml.
817 * Upgraded to autoconf 2.53 (from 2.13.)
819 4.02 * Plugged a few minor leaks in `xscreensaver' and `xscreensaver-demo'.
820 * New hacks, `cubenetic' and `fluidballs'.
821 * Sped up `pipes'.
822 * Fixed sphere projection error in `glplanet'; installed a better
823 image of earth.
824 * Added Win2K and MacOS 1 crashes to `bsod'.
825 * Put back previous (better) version of `forest' that was
826 accidentially downgraded in the last release.
827 * New version of `bumps'.
828 * Made FPS computation in GL hacks more efficient: it will influence
829 the results less, thus resulting in higher (but more accurate)
830 reported frame rates.
832 4.01 * New hacks: `twang', `glsnake', `boxed', `sballs', and
834 * New hacks `apollonian', `euler2d', `juggle', `polyominoes' and
835 `thornbird', from xlockmore.
836 * Merged recent xlockmore changes into `ant', `braid', `demon',
837 `discrete', `drift', `fadeplot', `forest', `grav', `hopalong',
838 `ifs', `laser', `lightning', `lisa', `lissie', `loop', `mountain',
839 `penrose', `rotor', `sierpinski', `slip', `sphere', `spiral',
840 `strange', and `vines'.
841 * Fixed the `gltext' bug that sometimes caused horizontal lines to
842 vanish again. This time for sure.
843 * Sped up `webcollage' by adding a C helper program to replace the PPM
844 pipeline. It also pastes images semi-transparently now.
845 * Added support for the gdk_pixbuf library: if this lib is available,
846 then `blitspin', `xflame', and `flag' can load GIF, JPEG, and PNG
847 images in addition to XPM and XBM.
848 * Fixed a rare race condition where the desktop-grabbing hacks could
849 sometimes leave the screen wedged, if the user moved the mouse
850 exactly when they were grabbing the screen image (it would un-wedge
851 the next time the saver timed out or was activated.)
852 * Fixed incorrect colors in the screen-grabbing GL hacks (`gflux' and
854 * Made SIGHUP restart the daemon process (though using
855 `xscreensaver-command -restart' is still the preferred way.)
856 * Tweaks to `xspirograph'.
857 * Minor configure and portability tweaks.
859 4.00 * Redesigned `xscreensaver-demo' GUI: it now includes small-preview
860 and per-hack configuration dialogs.
861 * Added three new modes of operation: `One Screen Saver', `Blank
862 Screen', and `Don't Blank' (in addition to the historical `Random
863 Screen Saver').
864 * Configure now defaults to installing the hacks in
865 <prefix>/lib/xscreensaver/ instead of <prefix>/bin/. (Most distros
866 already did it this way.)
867 * New GL hacks, `menger', `engine', `flipscreen3d'.
868 * Made `sierpinski3d' be more colorful.
869 * New versions of `xmatrix' and `nerverot'.
870 * Fixed a bug in `starwars' that made the font be drawn with thin
871 lines in -root mode.
872 * Fixed a bad colormap bug in `crystal' that could make *subsequent*
873 hacks malfunction!
874 * Made `gflux' able to grab screen images (`-mode grab').
875 * Updated `webcollage' for recent search engine changes.
876 * Removed most command-line options to `xscreensaver': just edit the
877 ~/.xscreensaver file instead.
878 * Improved behavior on multi-screen and Xinerama systems: the mouse
879 now stays on the screen where the user left it, and the password and
880 splash dialogs always appear on the screen that has the mouse.
881 * Made the splash dialog use more Gtk-like colors; made it have only
882 two buttons, "Settings" and "Help".
883 * Made `sonar' understand `.ssh/known_hosts2' format files, and be
884 better about stripping out illegal addresses.
886 3.34 * Turned `memoryLimit' off by default, sigh. Apparently some versions
887 of the GL libraries (appear to) allocate hundreds of megs for every
888 GL program, so `memoryLimit' was causing GL programs to malfunction
889 or crash on those systems.
890 * Improved fading on TrueColor XFree86 4.1.x systems.
891 * New GL hack, `circuit'.
892 * Added `fuzz' mode to `decayscreen'.
893 * New version of `whirlygig'.
894 * Added links to `xplanet' and `sphereEversion'.
895 * Fixed rare race condition that could make `sonar' hang.
896 * Fixed potential crash in `speedmine'.
897 * Made `xscreensaver-demo' not crash when imageDirectory was set to a
898 non-existent directory.
899 * Made `xscreensaver-getimage-video' invoke XawTV's `streamer' program
901 * Made `phosphor' and `starwars' deal with CR, LF, or CRLF line
903 * Changes for Cygwin compilation environments.
904 * Made `sonar' compile on systems that can't ping.
905 * Configure changes for HPUX 10.20.
906 * Made PAM code work on Red Had 4.2 systems.
907 * Made `xscreensaver-command -deactivate' work when the saver is not
908 active: what that does is reset the idle timer, as if keyboard input
909 had been detected. This was added for the benefit of people writing
910 DVD-playing software: they can now prevent the screensaver from
911 kicking in by sending a -deactivate message once a minute while the
912 movie is playing and not paused.
913 * Various minor portability tweaks.
915 3.33 * New hacks, `speedmine' and `whirlygig'.
916 * Sped up `pyro', made the explosions look a bit better.
917 * Added better stars to `glplanet' and `starwars'.
918 * Many internal changes to `webcollage'.
919 * Some new options to `attraction'.
920 * Minor fix to `noseguy' to avoid un-erased pixels.
921 * Rewrote the screen-eraser effects so that they complete in the same
922 amount of time regardless of how slow your X server is (some of them
923 were glacial on servers with slow blitting.)
924 * Fixed a potential free memory reference that could sometimes cause a
925 crash at startup.
926 * Possibly fixed a problem that could cause the daemon to crash with
927 an X error. I was never able to reproduce this problem, but I think
928 I might have figured out what caused it.
929 * Worked around a problem that caused PAM authentication to fail on
930 some Red Hat 7.x systems.
931 * Added a `memoryLimit' parameter that controls the amount of memory a
932 graphics hack may allocate: if they try to allocate more than this,
933 malloc() will fail (and they will exit or (safely) crash, rather
934 than hogging memory.) Default is 50M.
935 * Made `gnome-help-browser' be the default way to display man pages in
936 `xscreensaver-demo', if running on a GNOME system.
938 3.32 * The image-manipulating hacks (`slidescreen', etc.) can now operate
939 on randomly chosen image files from disk, or on frames captured from
940 the system's video input, instead of (or in addition to)
941 manipulating images of the desktop.
942 * Rewrote `vidwhacker' to use the new image-grabbing mechanism.
943 * Made fading work on TrueColor XFree86 4.x systems.
944 * Fixed a subtle rendering bug in `atlantis' (the fish were inside
946 * Made `atlantis' have a texture simulating light reflections from the
947 surface of the ocean.
948 * Fixed up label placement in `molecule'.
949 * Better color bars in `xteevee'.
950 * Made `install-strip' not try to strip scripts.
952 3.31 * Put in more sensible defaults for DPMS, and updated the
953 documentation to reflect the fact that all your DPMS settings are
954 now belong to xscreensaver.
955 * Fixed the `xscreensaver.spec' file so that `--force' is no longer
957 * New versions of `rotzoomer' and `nerverot'.
958 * Fixed an OSF/1 compilation problem in `molecule'.
960 3.30 * New hacks, `molecule', `dangerball', and `rotzoomer'.
961 * New version of `gflux'.
962 * Made `gltext' able to display the current time.
963 * Fixed a floating-point-precision problem in `gltext' that sometimes
964 caused horizontal lines to vanish.
965 * Removed the `-window-id' option from the hacks: it never worked
966 right, and was unnecessary.
967 * Made the `starwars' hack use thicker lines, antialias the text, and
968 fade out at the far edge instead of just dropping off.
969 * Fixed an SHM segment leak in `moire'.
971 3.29 * Better rendering of the new logo.
972 * New hack, `gltext'.
973 * Added `-planetary' option to `gears', to draw a different kind of
974 gear system.
975 * Made motion and rotation be smoother in `gears', `glplanet',
976 `moebius', `rubik', and `sierpinski3d'.
977 * Improved coloration in `sierpinski3d'.
978 * Made the GL hacks react to window size changes.
979 * Made most of the GL hacks take a -fps option (like `pulsar' did), so
980 you can use them to benchmark your 3D hardware.
981 * Fixed the previous fix to `sonar'.
982 * Minor fix to `nerverot'. Made sonar able to ping hosts on DEC OSF1.
983 * Eliminated a bogus "didn't get enough colors" warning in some of the
986 3.28 * New logo for xscreensaver!
987 * New hacks, `starwars' and `stonerview'.
988 * Made the motion of the bouncing ball in `stairs' be a little less
990 * Made newly-added screenhacks be added to .xscreensaver
991 automatically: if there are hacks in the app-defaults file that are
992 not also in ~/.xscreensaver, they will be added to the end of the
994 * Redid the `Screensaver Options' part of the control panel;
995 xscreensaver now lets you configure your DPMS settings.
996 * Fixed some Makefile problems with non-GL builds.
997 * Fixed detection of MesaGL for version 3.3.
998 * Better workaround to Red Hat 7.0's broken gcc.
999 * Added Sparc Solaris kernel panic to `bsod'.
1001 3.27 * New hacks: `zoom' and `whirlwindwarp'.
1002 * Fixed a free-memory-reference bug in `sonar'.
1003 * Better error handling when there are no suitable GL visuals.
1004 * Added diagnostic dialog when xscreensaver-demo is unable to launch
1005 xscreensaver (e.g., when running as root.)
1006 * Fixed a bug that caused screenhack argument changes to be ignored
1007 when xscreensaver-demo was running as root (if "root" and "nobody"
1008 have different home directories.)
1009 * Made the programs default to ":0" if $DISPLAY is unset.
1010 * Made the `-verbose' output include information about which server
1011 extensions were supported at compile time.
1012 * Worked around Red Hat 7.0's broken gcc 2.96.
1013 * Updated default delays on the GL hacks to look better on machines
1014 with super-fast 3D hardware.
1015 * Install `screensaver-properties-capplet' to work around the usual
1016 egregious GNOME lossage.
1018 3.26 * Added "enabled" checkboxes in the list of hacks in xscreensaver-demo
1019 (Gtk version only.)
1020 * New hacks `hyperball', `xrayswarm', and `gflux'.
1021 * New versions of `nerverot', `galaxy', and `hypercube'.
1022 * Small fixes to `phosphor', `shadebobs', `xflame', and `sonar'.
1023 * Added external helper program `xscreensaver-gl-helper' to figure out
1024 which X visual to use for OpenGL programs.
1025 * Configure updates for XFree86 4.0, and for BSD.
1026 * Made it be more tolerant of bogus /etc/group files.
1027 * When installing the PAM config file, first try to just copy an
1028 existing "xdm" or "login" config file, so that xscreensaver does
1029 authentication in the same way as the rest of the system.
1031 3.25 * New hack, `nerverot'.
1032 * Added BSD kernel panic to `bsod'.
1033 * New version of `shadebobs'.
1034 * New version of `petri'.
1035 * Updated `webcollage' to handle recent Altavista URL format changes;
1036 made it search the AP photo gallery.
1037 * Revamped command-line options of `sonar' and made it properly handle
1039 * The `bubbles' hack can now trickle up or down the screen.
1040 * The `xsublim' hack can now read its text from programs.
1041 * Support for GLE version 3 in `extrusion'.
1042 * Fixed compilation problems in `maze'.
1043 * Fixed a rare crash in `flow'.
1044 * Fixes for minor installation problems.
1046 3.24 * Added `-ignorant' option to `maze' hack.
1047 * Updates to `critical', `bsod', `xflame', and `flow'.
1048 * Added support for Kerberos 5 (via its Kerberos 4 compatibility
1050 * Fixed a bad leak in `xteevee'.
1051 * Updated `webcollage' to handle recent Altavista URL format changes.
1052 * Removed xscreensaver-demo's `Ok' and `Cancel' buttons, since they
1053 were confusing people: all changes are now instantanious.
1054 * Made xscreensaver-demo install itself into the Gnome Control Center.
1056 3.23 * Fixed some misplaced text fields in the Motif version of
1057 xscreensaver-demo; fixed a crash in the Gtk version that would
1058 happen if the programs list was empty.
1059 * Fixed a recently-introduced bug in `pulsar'.
1060 * Made `sierpinski3d' use solid tetrahedrons instead of points.
1061 * Added `-trace' option to `xmatrix'.
1062 * Added new hacks `xteevee' and `xspirograph'.
1064 3.22 * Fixed some bugs in xscreensaver-demo.
1065 * Rewrote the Motif version of xscreensaver-demo to match the new Gtk
1067 * The Athena toolkit is no longer supported.
1069 3.21 * Tweaked the xscreensaver-demo UI (Gtk only.)
1070 * Fixed a few visual selection bugs. I think the proper GL visual
1071 should be used with nVidia systems now.
1072 * Made the Makefiles obey $install_prefix.
1073 * Made the `xscreensaver.spec' file able to generate both GL and
1074 non-GL packages simultaneously.
1076 3.20 * Added new hacks `ripples' and `sierpinski3d'.
1077 * Made `xscreensaver-command -exit' be silent when no screen saver was
1078 running (instead of complaining.)
1079 * Made `webcollage' and `vidwhacker' use `xloadimage' when available
1080 (in addition to `xli' and `xv'.)
1081 * Improved memory usage in `petri' and gave it a hard cap on how much
1082 memory it can allocate.
1083 * Added `-watch' option to `xscreensaver-command'.
1084 * Made `xscreensaver-demo' come up with the most-recently-run hack
1085 selected by default.
1086 * Rewrote the Gtk version of `xscreensaver-demo'. It's a lot easier
1087 to use now.
1088 * Extended the format of the programs list in the .xscreensaver file,
1089 for the benefit of the new capabilities of `xscreensaver-demo'.
1090 NOTE: you might want to delete your ~/.xscreensaver file and allow
1091 it to be re-created! The old one should still work, but
1092 xscreensaver-demo won't be as pretty.
1094 3.19 * Fixed gcc dependencies in `bumps' and `ccurve'.
1095 * New hack, `extrusion'.
1096 * Some of the web sites that `webcollage' was using as its sources
1097 changed formats; tweaked it to understand the current layouts.
1098 * Added typeahead in the password dialog: if the screen is locked, and
1099 you unlock it by typing a character, that key will be automatically
1100 inserted in the password dialog (unless it is Return, Enter, Space,
1101 or a non-printing key like Shift.)
1102 * Made `xmatrix' take a `-small' option, since some folks with tiny
1103 screens prefer a smaller font.
1105 3.18 * New versions of `shadebobs', `lmorph', and `distort'.
1106 * Added `ccurve', `blaster', and `bumps' hacks.
1107 * Replaced `forest' hack with a rewritten version.
1108 * Worked around a Xinerama server bug.
1109 * Fixed a bug I introduced in 3.10 that caused some hacks to print out
1110 superfluous warnings about not having gotten enough colors.
1111 * Made `sproingies' obey the `-delay' option.
1112 * Fixed a portability bug in `shadebobs'.
1113 * Made `webcollage' and `vidwhacker' use `xli' in preference to `xv',
1114 if it is available.
1115 * Added a new source of images to `webcollage'.
1116 * If running under KDE, xscreensaver will add itself to KDE's list of
1117 screensavers (via xscreensaver.kss.)
1118 * Improved detection of GL libraries.
1119 * Made the password dialog include the date and time.
1121 3.17 * New version of `webcollage' -- deals better with corrupted images,
1122 and can use an http proxy.
1123 * New hack, `xsublim' (run it in the background, rather than adding it
1124 to the programs list.)
1125 * The xscreensaver daemon was leaking a file descriptor each time you
1126 edited your .xscreensaver file. Fixed.
1128 3.16 * New version of `shadebobs'.
1129 * Improved image selection in `webcollage', and sped it up slightly.
1130 * Made configure find the right version of perl.
1131 * Rewrote the CGI part of `webcollage'.
1132 * `make clean' was deleting some things it shouldn't.
1133 * Fixed a typo in the default programs list.
1135 3.15 * Added `webcollage' and `shadebobs' hacks.
1136 * Added a `-stdout' arg to `vidwhacker' so that it can be used in a
1138 * Made `petri' use less memory.
1140 3.14 * Various improvements to the Gtk port.
1141 * Turned off PAM by default on Solaris, since PAM seems generally to
1142 be misconfigured out-of-the-box.
1143 * Made the `--without-gtk' configure option work.
1144 * Made configure check the Gtk version number, since it requires 1.2.
1145 * Fixed a bug in the code that attempted to prevent changes of screen
1146 resolution while the screen is locked.
1147 * Fixed a race condition in `xscreensaver-demo' that could cause an X
1148 error at startup.
1149 * Added `-transparent' option to `deluxe'.
1150 * Added `petri' hack.
1152 3.13 * Ported `xscreensaver-demo' to Gtk.
1153 * Made it possible to build Motif, Gtk, and Athena versions of
1154 `xscreensaver-demo' in the same directory without reconfiguring.
1155 * Made `xscreensaver-demo' chase symlinks before writing the
1156 .xscreensaver file, so that if .xscreensaver is itself a symlink,
1157 the underlying file will be replaced instead.
1158 * Some Makefile and configure tweaks for Solaris and FreeBSD.
1159 * Made it possible to set the fire color in `xflame'.
1160 * Made transparency work in TrueColor (for `goop' and `qix'.)
1161 * Fixed a multi-head bug introduced by the virtual viewports stuff.
1164 3.12 * Made it so that you can't scroll the screen while the lock dialog is
1165 up (with XFree86 virtual viewports.)
1166 * Fixed a bug in `flag' that caused bob's chin to get cut off after a
1167 few iterations.
1169 3.11 * Made `xjack' be black-on-white-ish, so that it looks less like a
1170 computer screen and more like the typewritten paper it's supposed to
1172 * New version of `pulsar'.
1173 * Fixed Solaris compilation problem in `phosphor'.
1174 * Made xscreensaver notice XFree86's virtual root window hack, so that
1175 if the X server's root window is larger than the monitor's
1176 displayable resolution, the screen saver will limit itself to the
1177 area that actually appears on the screen.
1178 * Made the xscreensaver daemon do a better job of picking the visual
1179 class that should be used for GL programs. Less user intervention
1180 should be needed now: you can use the logical visual name `GL'
1181 instead of having to figure out by hand which one to use.
1182 * Oops, the visual was defaulting to "best" instead of
1183 "default", because the .xscreensaver file was not being
1184 loaded quite early enough.
1185 * Made configure figure out how to build icmp ping support into the
1186 `sonar' hack automatically.
1187 * Made warnings about not being able to read shadow passwords not be
1188 printed if compiled with PAM support.
1189 * Improved PAM startup diagnostics.
1190 * Worked around the Solaris PAM bug that was causing crashes there, so
1191 now PAM is turned on by default.
1192 * Made configure detect the number of arguments that pam_strerror()
1193 takes, since on Linux, this apparently changed between 2.0 and 2.2,
1195 * Made the /proc/interrupts kludge look for "PS/2 Mouse" as well as
1197 * Made xscreensaver notice when there has been a sudden large jump in
1198 wall-clock time, and if so, lock right away, instead of waiting for
1199 "lockTimeout" to expire first. (Laptops need this for safer
1200 recovery from hibernation.)
1201 * Added `-throttle' option to `xscreensaver-command'.
1203 3.10 * Added `phosphor', `xmatrix', and `pulsar' hacks.
1204 * Fixed a bug in the color allocator that sometimes caused `starfish'
1205 to fall back to monochrome.
1206 * Reduced the amount of code that runs before root privileges are
1207 disavowed: "normal" and "shadow" passwords now do some
1208 initialization as root, but the PAM and Kerberos authorization
1209 schemes will be initialized while running as "nobody". Supposedly
1210 this closes a potential security hole when using Kerberos.
1211 * Added some more sanity checking to configure.
1213 3.09 * Added `compass', `squiral', `xflame', `wander', `spotlight', and
1214 `critical' hacks.
1215 * Added some new modes to `decayscreen'.
1216 * Made `deluxe' work in monochrome.
1217 * Generalized usage of the Double-Buffer server extension in several
1218 hacks (`compass', `deluxe', `interference', `kumppa', and `moire2'.)
1219 * Fixed another visual-depth problem in `rd-bomb'.
1220 * The screen saver will now defer blanking if neither the keyboard nor
1221 the mouse could be grabbed. Instead, it will just try again in a
1222 few minutes. This fixes a bad interaction between xscreensaver and
1223 programs like VMware that hold the mouse and keyboard grabbed for a
1224 long time.
1225 * Added a new erase mode (expanding spiral.)
1227 3.08 * Fixed some bugs in my port of `t3d'.
1228 * Added `penetrate' and `deluxe' hacks.
1229 * When linking against Motif 2.x, also link against XPM.
1230 * Added support for using /proc/interrupts for idle detection on
1231 Linux. Now xscreensaver shouldn't kick in when the user is active
1232 on a non-X virtual console.
1233 * Upgraded to autoconf 2.13.
1235 3.07 * Configure tweaks (sometimes -lXmu wasn't getting linked in properly;
1236 check for _Xsetlocale in -lXintl.)
1237 * Portability fixes for sonar.c.
1238 * Fixed a compilation problem when you have GL but don't have XPM.
1239 * Made configure notice when MesaGL requires -lpthread.
1240 * Made `flame' ignore SIGFPE (not sure if this is the right fix; it
1241 seems only to be needed on FreeBSD.)
1242 * Kludged `rd-bomb' work on visuals that are of depth 24 but that *do
1243 not* support pixmaps of depth 32.
1244 * Fixed `halo' to work properly in TrueColor.
1245 * Changed `xscreensaver.spec' to install the hacks in
1246 /usr/X11R6/lib/xscreensaver/ by default, since that's where recent
1247 Red Hat distributions put them.
1248 * Added `t3d' hack.
1249 * Updated versions of `crystal', `hopalong', and `flow' from
1251 * Imported `demon' and `loop' modes from xlockmore.
1253 3.06 * Oops, the "default-n" visual descriptor was broken; it was always
1254 installing a colormap if the `installColormap' preference was set,
1255 meaning that `xearth', `xv' and friends were using the wrong colors
1256 on 8-bit systems.
1257 * Turned off HAVE_PING in `sonar', since it compiles on some Linux
1258 systems, but not others of similar vintage...
1260 3.05 * Fixed an off-by-1 in `distort'.
1261 * Added `sonar' hack.
1262 * New version of `glplanet' (with stars.)
1263 * Made all hacks exit when you type `q' or `ESC' at them, and made
1264 them obey the WM_DELETE_WINDOW ClientMessage.
1265 * Fixed a nonfatal buffer overrun in lament (note: lament still
1266 doesn't work with MesaGL 3.0: it dies in
1267 lambda_textured_triangle1(), which is Mesa's bug, not mine.)
1269 3.04 * Added an `xscreensaver.spec' file, to make it easier for other folks
1270 to generate RPMs.
1271 * Made the password code work on HPUX in the situation where:
1272 "enhanced security" is available; but not used; but the user typed
1273 a password more than 8 characters long anyway. FTSOHPUX.
1275 3.03 * Made locking work when passwd aging is enabled.
1276 * Added support for PAM (Pluggable Authentication Modules.) It is
1277 still turned off by default, though, since it doesn't seem to work
1278 on Solaris 2.6, and has been behaving erratically on Red Hat 5.1.
1279 * Made each possible authentication method be tried in turn until one
1280 succeeds; this means that Kerberos is being used, we will first
1281 check Kerberos, and if that fails, will then consult the local
1282 password file. Likewise with PAM.
1283 * Save and restore the bits under the passwd dialog, to avoid leaving
1284 a black rectangle behind when unlocking is cancelled.
1286 3.02 * Not everyone has sys/select.h, sigh...
1288 3.01 * Some fixes to `reflect'.
1289 * Configure tweaks.
1290 * Made it log unsuccessful attempts to unlock the screen to syslog.
1291 * Fixed a bug where `xscreensaver-demo' could be seeing a different
1292 programs list than `xscreensaver' did.
1294 3.00 * The xscreensaver daemon no longer links against Motif or Athena:
1295 demo-mode and the preferences panel are no longer built in to the
1296 daemon, but are now handled by an external program,
1297 `xscreensaver-demo'. (I decided that this, along with the recent
1298 addition of the `.xscreensaver' config file, justified bumping the
1299 version number to 3.00, since this is a fairly major architectural
1301 * Lines in the `*programs' resource may now begin with the character
1302 "-", meaning "don't run this hack." In this way, it's possible to
1303 disable a hack without throwing away the information about it
1304 (making it easier to change your mind later.) Eventually the
1305 preferences/demo mode GUI should represent this as a checkbox or
1307 * Fixed a short race condition where it was possible for xscreensaver
1308 to die with a BadWindow error if it was blanking the screen just as
1309 another window was being deleted.
1310 * Made it possible to disable specific modes in `bsod'.
1312 2.34 * Fixed a bug that was making `pipes' generate way too many valves.
1313 Made the viewpoint in `pipes' be selected randomly instead of always
1314 being -10 degrees.
1315 * Fixed a bug in the XSHM code, in the case where the server supports
1316 the XSHM extension but is not the same machine as the client.
1317 * Made `rd-bomb' default to taking up the whole screen.
1318 * Made it not try to do fading/unfading if no PseudoColor visuals
1320 * Initial attempt at supporting VT-locking (doesn't work yet.)
1321 * Eliminated the `captureStdout' resource; now `captureStderr'
1322 controls both streams.
1323 * Added `-capture-stderr' and `-no-capture-stderr' command-line
1325 * Added `glplanet' hack.
1326 * When a hack is selected with `xscreensaver-command -select', that
1327 hack will be used until further notice (until the saver turns off,
1328 or another activation command is issued.)
1330 2.33 * Made `xscreensaver-command' print error messages: the xscreensaver
1331 daemon now responds to ClientMessage events by writing a response
1332 message on a window property, instead of just writing to its stderr.
1333 * Made the ~/.xscreensaver file be automatically reloaded when the
1334 file date changes.
1335 * The password dialog and splash screen no longer depend on Motif or
1336 Athena. This should clear up a number of focus problems, and is the
1337 first step on the path toward moving all of the
1338 Motif/Athena/whatever code out of the xscreensaver daemon, and into
1339 external processes.
1340 * Don't complain about LessTif 0.86 any more, since the new password
1341 dialog makes that problem go away.
1342 * Configure tweaks for Irix 6.5, SunOS 5.something.
1343 * New `-reflect' option to `distort'.
1345 2.32 * Added reading and writing of a ~/.xscreensaver file, so that the
1346 Preferences panel can save its settings.
1347 * New version of `rubik'.
1348 * Added `-select N' argument to `xscreensaver-command'.
1349 * Oops, left out some of the `bubbles3d' files...
1351 2.31 * The cursor was invisible in the password dialog. Fixed.
1352 * Made configure warn against MesaGL 2.6.
1353 * Fixed X error at startup when using non-default visual.
1354 * New version of `crystal', `ant', and `atlantis' from xlockmore.
1355 * New hack, `bubble3d'.
1356 * Added some new modes to `bsod'.
1358 2.30 * Changed the order in which -lSM and -lICE are linked to be after
1359 Motif instead of before (Lesstif on Irix needs this.)
1361 2.29 * Work around a bash bug in configure.
1362 * Tweaked HPUX paths again. FTSOHPUX.
1363 * Made configure recommend against LessTif 0.86, due to a bug in that
1364 version that causes a security hole in the screen locking code.
1365 LessTif 0.87 will fix it.
1366 * Made all of the `--with' options to `configure' accept a directory
1367 option as well (so that --with-motif=/FOO will add -I/FOO/include
1368 -L/FOO/lib). I believe this is the Configure Party Line of how do
1369 to such things.
1370 * Fixed a bug where the mouse was left un-grabbed after the first time
1371 the graphics hack was changed (simplified all of the mouse-grabbing
1373 * Maybe possibly perhaps made `vidwhacker' really not leave stray xv
1374 windows around. This time for sure.
1375 * Added a new erase mode (random dots fizzling out.)
1376 * Added `-prefs' argument to `xscreensaver-command', that brings up
1377 the Preferences dialog directly (it seems that nobody ever noticed
1378 the `Preferences' button on the Demo Mode dialog, maybe this will
1380 * Added a splash screen. Turn it off with *splash:false.
1382 2.28 * Better macsbug text in `bsod'.
1383 * New version of `distort' with many new modes.
1384 * Plugged a leak in `coral'.
1385 * Tweaked configure for HPUX.
1386 * Removed some compiler warnings.
1387 * More consistent usage of stderr versus stdout.
1388 * More diagnostics should an X error occur.
1389 * Fixed a possible crash in SGI-specific unfading code.
1391 2.27 * Improved version of `distort'.
1392 * Made `lament' compile against OpenGL 1.0 (though it still requires
1393 1.1 to work properly.)
1394 * Updated my email address and home page.
1396 2.25 * Improved motion in `rd-bomb'.
1397 * Added XSHM (shared memory extension) support to the `distort',
1398 `interference', `moire', `rd-bomb', and `swirl' hacks, which speeds
1399 them up a bit.
1400 * Added `lament' hack.
1402 2.24 * Tweaked the order of the -L options again.
1403 * Cleaned up configure's `--help' message.
1404 * Added `kumppa' hack.
1405 * Smarter maze-solving algorithm in `maze'.
1406 * Took `xlyap' out of the default list of hacks, since it's just
1407 incredibly buggy (and slow.) Maybe someday someone will fix it...
1408 * Added `distort' hack, but didn't add it to the default list (yet)
1409 because it's still too slow.
1410 * Made the Athena demo dialog look more like the Motif version; it has
1411 a text-entry field now, too.
1412 * Made the Athena password dialog echo asterisks, like Motif does,
1413 instead of using a flyspeck font.
1414 * Some random configure tweaks.
1415 * Added a `timestamp' resource that makes the `-verbose' messages
1416 include the time at which they were printed.
1418 2.23 * The fix for SGI's "scheme" nonsense broke things, and let the
1419 user's "*background" resource show through. Fixed it in a different
1422 2.22 * Added support for the DPMS server extension (Display Power
1423 Management System.)
1424 * Made configure advertize the `--enable-subdir' option a little more,
1425 since that seemed to cause some people stress. Also, made that
1426 directory be built into the xscreensaver executable, as a hardcoded
1427 prefix to $PATH. (Might help, shouldn't hurt.)
1428 * Made configure prefer the two-arg gettimeofday to the one-arg
1429 version, since AIX doesn't have any prototypes.
1430 * Made it work with Xaw3d (the 3D Athena library.)
1431 * Made `make install' create directories as necessary.
1432 * New version of lmorph from Sverre.
1433 * Added `crystal' and `discreet' hacks from xlockmore.
1434 * Added a new mode to `bsod'.
1436 2.21 * Made `xscreensaver-command -time' use different words. (It now
1437 describes the two states as "screen blanked since..." and "screen
1438 non-blanked since..." instead of "active since..." and "inactive
1439 since..." which a lot of people interpreted as meaning the opposite
1440 of what was intended.)
1441 * Improved some error messages, in the hopes of making the distinction
1442 between the xscreensaver and xscreensaver-command programs more
1444 * Rewrote (and reorganized) parts of the xscreensaver and
1445 xscreensaver-command manual pages.
1446 * Renamed xscreensaver's `-lock' command-line option to be
1447 `-lock-mode', to avoid confusion with the `-lock' option to
1448 xscreensaver-command, which does a totally different thing.
1449 * Removed xscreensaver's `-demo' command-line option for a similar
1450 reason; use `xscreensaver-command -demo' instead.
