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 2.2 and MacOS X 10.4.0

39 ===============================================================================
41 Changes since 5.02: * New hacks, `cwaves', `glcells', `m6502', and `voronoi'.
42 * Minor fixes to `bsod'.
43 * Fixed possible crash with PAM USB-dongle auth.
44 * Updated `webcollage' to track recent Google Images
46 Changes since 5.01: * Reworked PAM code to support fingerprint readers, etc.
47 * Ported 'webcollage' to OSX.
48 * Added OSX 10.2 and 10.3 kernel panics to `bsod'.
49 * Fixed a Xinerama crash when changing the screen count.
50 * New blobbier `mirrorblob'.
51 * Minor updates to `lisa', `bsod', `ifs', `hypertorus',
52 `polytopes', `circuit', `endgame', `crackberg',
53 `flipflop', `flipscreen3d', `fliptext', and `carousel'.
54 * Enabled multi-threaded OpenGL on OSX.
55 Changes since 5.00: * Backed out recent locale-related changes, since they
56 broke far more things than they fixed.
57 * Fail gracefully with ridiculously small window sizes.
58 * `xflame' and `flag' ignore bitmap option on MacOS.
59 * `speedmine' prefs work on MacOS.
60 * Better explosions in `boxed'.
61 * More dynamic motion in `sproingies'.
62 * More options in `flipflop'.
63 * Minor updates to `topblock'.
64 * Various other minor fixes.
65 Changes since 4.24: * Ported to MacOS X! (10.4.0 or newer)
66 * API change: instead of providing a single screenhack()
67 function that does not return, screen savers using the
68 screenhack.h framework must now provide "init" and
69 "draw one frame" functions instead. All bundled savers
70 have been updated; third-party patches will need work.
71 * All image-loading happens asynchronously.
72 * xscreensaver-getimage-file caches the contents of the
73 image directory for a few hours, so consecutive runs
74 won't have to re-list the whole directory tree.
75 * New hacks, `topblock' and `glschool'.
76 * Removed `xteevee' (superceded by `xanalogtv').
77 * Added variable-sized puzzle pieces to `jigsaw'.
78 * Changes to the defaults and command-line options of
79 many hacks to make the .xml files more consistent.
80 * Reap zombies in `glslideshow' and `carousel'.

83 * `endgame' has higher resolution chess-piece models.
84 * `webcollage' takes a -directory option to get images
85 from a local directory.
86 * The RPM spec file no longer auto-restarts xscreensaver
87 when a new version is installed. Restart it manually.
88 Changes since 4.23: * New versions of `cube21', `glsnake', `celtic'.
89 * Backed out a DPMS-related patch that cause desktop
90 flickering with some X servers.
91 * Fixed startup crash in getgroups() when running setuid.
92 * Default to not displaying stderr on the saver window.
93 * Fixed bad free() in "Documentation" button.
94 * Don't try to run hacks that aren't installed.
95 * Minor fixes to various XML config files and man pages.
96 Changes since 4.22: * New hacks, `glhanoi', `cube21', `timetunnel',
97 `juggler3d', and `celtic'.
98 * New versions of `tangram', `webcollage', `hypertorus',
99 `polytopes', and `ripples'.
100 * `sonar' is now quiet about unresolvable hosts.
101 * Minor corrections to BASIC code in `apple2'.
102 * xscreensaver-demo now provides an RPM clue when none
103 of the hacks seem to be installed.
104 * Don't install `ant' by default, since there is some
105 Java tool of that name, which was causing confusion.
106 And also it's boring.
107 * Made screen grabbing work again on MacOS 10.4.2.
108 * No longer prints bogus warnings about ClientMessages
109 intended for the window manager.
110 * Ignore unprintable characters in passwd entry field.
111 * Fixed yet another cross-host-display image-loading
113 * `xscreensaver-command -watch' and `-time' now work
115 Changes since 4.21: * Fixed a bug in the new mouse-motion code that caused
116 the screen to never blank on multi-head non-Xinerama
118 * New hacks, `interaggregate', `antmaze', `tangram',
120 * Minor tweaks to `fiberlamp', `ifs', `slidescreen',
121 `zoom', `sonar', `fireworkx', `whirlwindwarp',
122 `bubble3d', and `rd-bomb'.
123 * Added motion blur to `blinkbox'.
124 * `bsod' now includes Longhorn's "RSOD", and OS/2.
125 * Fixed `-wireframe' usage in most hacks and man pages.
126 Changes since 4.20: * New hack: `fliptext'.
127 * Changed default configure installation directories:
128 /usr/bin/ for xscreensaver, etc.;
129 /usr/libexec/xscreensaver/ for hacks;
130 /usr/share/xscreensaver/config/ for xml files.
131 * All the text-manipulating screen savers can have their
132 text source configured via `xscreensaver-demo' now.
133 * xscreensaver.spec now builds three RPMs:
134 base (no hacks); extras (2d hacks); and gl-extras.
135 * Added `-program' and `-front' option to `gltext'.
136 * Added `-shells' to `molecule'.
137 * Fixed text-alpha glitch in `carousel'.
138 * New `pacman': the ghosts can be killed now.
139 * Fixed a bug in screen-grabbing GL hacks where images
140 would be tiled instead of scaled on machines that
141 can't do large textures.
142 * `webcollage' can hit Flickr now.
143 * New (rewritten) implementation of `ifs'.
144 * The unlock dialog can be made to have a "New Login"
145 button that will run `gdmflexiserver'. Experimental!
146 * Fixed non-ASCII display bug in `starwars'.
147 * Configure finds a default for imageDirectory.
148 * "xscreensaver-command -lock" now works even if
149 in "screensaver disabled" mode.
150 * If a bad password is typed while CapsLock is on, the
151 unlock dialog says "CapsLock?" instead of "Sorry".
152 * Mouse motion only counts as activity if the mouse moved
153 more than 10 pixels (so the screen won't unblank every
154 time you bump your desk.)
155 * New mode option "random-same": if you have multiple
156 monitors, this will run the *same* randomly chosen
157 hack on each screen, instead of different ones on each.
158 Changes since 4.19: * New hacks, `fiberlamp', `boing', `boxfit', and
160 * Rewrote `glslideshow' again: should be faster now.
161 * Sped up loading of images in GL programs.
162 * `starwars' uses texture-mapped fonts now.
163 * New `bsod' modes: tru64, hppa, and nvidia.
164 * Updates to `webcollage', `juggle', `pinion',
165 `fireworkx', `sonar', `extrusion', `substrate', and
167 Changes since 4.18: * New hacks, `substrate', `intermomentary', `fireworkx',
169 * New version of `flow'.
170 * Made /proc/interrupts work again on Linux 2.6.
171 * Made `analogtv' not hog the CPU.
172 * Made analogtv-based hacks work properly on PPC/ARM.
173 * Fixed a bad memory leak in `piecewise'.
174 * Minor updates to `sonar', `molecule', `glmatrix',
175 `galaxy', and `webcollage'.
176 * Removed support for GTK 1.x (everyone uses 2.x now.)
177 Changes since 4.17: * Oops, pay no attention to the man behind the curtain.
178 Changes since 4.16: * New hacks, `anemotaxis' and `memscroller'.
179 * Fixed a bad bug that caused `vidwhacker' to never die.
180 * Fixed normals and lighting in `polyhedra'.
181 * Don't reuse the window when changing hacks (to work
182 around bugs in some GL implementations.)
183 * Made `xscreensaver-getimage-file' skip thumbnail-sized
185 * Fixed endian problem in `barcode' on non-x86.
186 * Updates to `webcollage', `apple2', `fuzzyflakes',
187 `atunnel', and `pacman'.
188 * Timing tweaks to `bubble3d', `bouncingcow', `engine',
189 `gltext', `lavalite', `molecule', `spotlight',
190 `sballs', `boxed', `blinkbox', and `circuit'.
191 * Configure updates for Fedora core 2 / xorg 6.7.0.
192 * Compile without warnings under gcc 3.3.3.
193 * I give up: don't blank or lock the screen if we can't
194 get a keyboard grab. In that case, both choices are
196 Changes since 4.15: * New hacks, `polyhedra', `fuzzyflakes', `antinspect',
198 * Minor updates to `webcollage', `bsod', `endgame',
199 `antspotlight', `xmatrix', and `glmatrix'.
200 * Added support for the RANDR (Resize and Rotate)
201 extension to detect when the size of the desktop has
202 been changed while xscreensaver is already running.
203 * Possibly-futile attempt to work around "rdesktop"
205 * Made `xscreensaver-getimage -file' still work even if
206 imageDirectory is unset.
207 * Convert Latin1 to ASCII in `starwars' and `phosphor'
208 (since the GLUT font only has ASCII glyphs.)
209 * Fixed randomization in `noof'.
210 * Added "GetViewPortIsFullOfLies" preference to work
211 around longstanding XFree86 bug #421.
212 * Made `sonar' subnet pinging work properly on bigendian
213 machines (e.g., PPC.)
214 Changes since 4.14: * New hacks, `wormhole', `mismunch', `noof', and
216 * `phosphor' and `apple2' include vt100 emulators now:
217 this means you can do "phosphor -program top", or
218 can use either program as an xterm replacement:
219 "apple2 -text -fast -program 'xemacs -nw'".
220 * `analogtv' (and related) fill the screen better.
221 * The '-gradient' option works in `atlantis' now.
222 * Minor updates to `blinkbox', `queens', `endgame',
223 `glmatrix', `mirrorblob', `blocktube', and `molecule'.
224 * Integrated SuSE's "external passwd helper" support.
225 * Marginally better /tmp handling in various programs.
226 * Updated config defaults for xplanet 1.0.3.
228 Changes since 4.13: * New hacks, `fontglide', `apple2', `xanalogtv', `pong',
229 `gleidescope', `mirrorblob', and `blinkbox'.
230 * New version of `glsnake' (with many more models.)
231 * Another Windows crash in `bsod'; also HVX/GCOS6/TPS6.
232 * New version of `endgame'.
233 * Screen grabbing works on MacOS X.
234 * Various minor fixes.
235 Changes since 4.12: * On Xinerama systems, xscreensaver now runs one hack on
236 each monitor (just like in "real" multi-head mode)
237 instead of running one hack stretching across all the
238 screens. Note that for this to work with any 3rd party
239 screensavers, they must update their "vroot.h" file.
240 * `webcollage' and `vidwhacker' display images using
241 `xscreensaver-getimage' now.
242 * Added `ljlatest' script for use with `starwars' and
244 Changes since 4.11: * New GL hacks, `flipflop', `antspotlight', and
246 * Added VMS to `bsod'.
247 * Compile without warnings in "gcc -pedantic".
248 * Updates to `webcollage' and `queens'.
249 * Fixed a bug that could cause PAM to hang.
250 Changes since 4.10: * New hacks, `hypertorus', `cubestorm', `glknots',
251 `blocktube', and `glmatrix'.
252 * Updates to `cloudlife', `engine', `xmatrix', and
254 * Rewrote `glslideshow': it should work on somewhat
255 wimpier video cards now.
256 * Various portability tweaks.
257 Changes since 4.09: * New hacks, `cloudlife' and `klein'.
258 * Added Apple ][+, HPUX, and OS/390 sessions to BSOD.
259 * Added some Matrix Reloaded text to `xmatrix'.
260 * Updates to `webcollage', `eruption', `jigglypuff',
261 `metaballs', and `endgame'.
262 * Completely ignore the `memoryLimit' setting now,
263 since it was still causing people GL grief.
264 * Various minor fixes.
265 Changes since 4.08: * New hacks, `flyingtoasters', `bouncingcow',
266 `jigglypuff', and `glslideshow'.
267 * More models in `engine'.
268 * Rewrote `xscreensaver-getimage' to remove reliance on
269 external image loaders (xv, chbg, xloadimage, etc.)
270 and to reduce flicker when loading files.
271 * Made `gflux' and `flipscreen3d' be mouse-spinnable.
272 Changes since 4.07: * New hacks, `atunnels' and `piecewise'.
273 * Physics improvement in `fluidballs'.
274 * Various fixes for XDarwin systems (X11 on MacOS X.)
275 * Added -clock option to `barcode'.
276 * Minor fixes to `endgame', `flurry', `flipscreen3d',
278 Changes since 4.06: * New hacks, `flurry', `metaballs', `eruption',
279 `popsquares', and `barcode'.
280 * Minor updates to `maze' for high density mazes.
281 * Added double buffering to `fluidballs' and `whirlygig'.
282 * Bug fixes for running xscreensaver to a remote XFree86
283 display (which nobody would ever do...)
284 * Updated `webcollage' (faster Alta Vista searching.)
285 * Updated `glplanet' so the sun sets in the west.
286 * Updated `sproingies' with smooth, unsegmented surfaces.
287 * Fixed Perl version-sensitivity in
288 `xscreensaver-getimage-file'.
289 * Fixed GTK2 scrolling bug in `xscreensaver-demo'.
290 Changes since 4.05: * New hack, `glblur' (disabled by default, since it
291 requires fast OpenGL texture support.)
292 * New hack, `halftone'.
293 * Updates to `endgame', `queens', `bumps', `glplanet',
294 `engine', and `circuit'.
295 * New version of `menger' that uses far fewer polygons.
296 * Fixed minor bug in `critical' that could cause some
297 bogus X servers to crash.
298 * Better labels in `molecule': the labels now appear to
299 be attached to the atoms, instead of floating in front
301 * Fixed bug that could rarely cause GL hacks to fail to
302 double-buffer (causing intermittent flickering.)
303 * Fixed a relative-URL-parsing bug in `webcollage'.
304 * Fixed a bug that (sometimes) caused the window manager
305 close box to kill `xscreensaver-demo' with a crash
306 instead of a graceful exit.
307 * Updated xscreensaver.pam to the Red Hat 7.3 way.
308 * More Gnome2-related configure crap.
309 * Updated to latest `config.guess' and `config.sub'.
310 * Fixed occasional core dump in `distort'.
311 * Added a Linux fsck failure and kernel panic to `bsod'.
312 * Added MacOS X kernel panic to `bsod'.
313 * Fixed a bug in `bsod' (all bsod bugs are ironic.)
314 * Fixed a bug that caused `xscreensaver-gl-helper' to
315 print a nonsense visual ID with some versions of
316 `printf': this could cause GL programs to display
317 incorrectly (e.g., flickery.)
318 Changes since 4.04: * More `configure' tweaks to try and get things working
319 on systems that both Gtk 1.x and 2.x installed.
320 * New hack, `endgame'.
321 * Minor updates to `gltext'.
322 Changes since 4.03: * Support for GTK 2.x / GNOME 2.x.
323 * The `configure' script will now use `pkg-config' if
324 you have it, in preference to `gtk-config', etc.
325 * New hacks, `lavalite', `queens', and `anemone'.
326 * Minor updates to `spheremonics', `gltext', `xmatrix'.
327 * You can use the mouse to manually spin most of the GL
328 hacks now (when they are displaying in a window.)
329 * Fixed a bug in `webcollage' (due to recent Alta Vista
330 url changes) that was causing it to try and load
331 incorrect image URLs.
332 * Made `xscreensaver-getimage' use gdk_pixbuf if it is
333 available: this means that those hacks that load images
334 will no longer rely on "xv", "xloadimage", etc. This
335 will close a race condition that could sometimes cause
336 your desktop background to be changed; and also makes
337 it possible for those programs to operate on image
338 files when running in windowed mode.
339 * `webcollage' can now be used in conjunction with
340 `driftnet' to display images snooped from your local
341 ethernet instead of obtained from search engines.
342 * Added man pages for all the hacks that didn't have
344 Changes since 4.02: * New hack, `spheremonics'.
345 * Minor updates to `webcollage', `cage', `moebius',
346 `morph3d', `boxed', `circuit', and `helix'.
347 * `pulsar' and `extrusion' can now load texture JPEGs.
348 * `rubik' now does non-square cubes.
349 * `fluidballs' now does various sizes of balls.
350 * `menger' and `sierpinski3d' now also show polygon
352 * `molecule' displays real subscripts in the formulae.
353 * GTK internationalization/localization support.
354 * Better detection of the various versions of libxml.
355 * Upgraded to autoconf 2.53 (from 2.13.)
356 Changes since 4.01: * Plugged a few minor leaks in `xscreensaver' and
358 * New hacks, `cubenetic' and `fluidballs'.
360 * Fixed sphere projection error in `glplanet'; installed
361 a better image of earth.
362 * Added Win2K and MacOS 1 crashes to `bsod'.
363 * Put back previous (better) version of `forest' that
364 was accidentially downgraded in the last release.
365 * New version of `bumps'.
366 * Made FPS computation in GL hacks more efficient: it
367 will influence the results less, thus resulting in
368 higher (but more accurate) reported frame rates.
369 Changes since 4.00: * New hacks: `twang', `glsnake', `boxed', `sballs',
371 * New hacks `apollonian', `euler2d', `juggle',
372 `polyominoes' and `thornbird', from xlockmore.
373 * Merged recent xlockmore changes into `ant', `braid',
374 `demon', `discrete', `drift', `fadeplot', `forest',
375 `grav', `hopalong', `ifs', `laser', `lightning',
376 `lisa', `lissie', `loop', `mountain', `penrose',
377 `rotor', `sierpinski', `slip', `sphere', `spiral',
378 `strange', and `vines'.
379 * Fixed the `gltext' bug that sometimes caused
380 horizontal lines to vanish again. This time for sure.
381 * Sped up `webcollage' by adding a C helper program to
382 replace the PPM pipeline. It also pastes images
383 semi-transparently now.
384 * Added support for the gdk_pixbuf library: if this lib
385 is available, then `blitspin', `xflame', and `flag'
386 can load GIF, JPEG, and PNG images in addition to XPM
388 * Fixed a rare race condition where the desktop-grabbing
389 hacks could sometimes leave the screen wedged, if the
390 user moved the mouse exactly when they were grabbing
391 the screen image (it would un-wedge the next time the
392 saver timed out or was activated.)
393 * Fixed incorrect colors in the screen-grabbing GL hacks
394 (`gflux' and `flipscreen3d'.)
395 * Made SIGHUP restart the daemon process (though using
396 `xscreensaver-command -restart' is still the preferred
398 * Tweaks to `xspirograph'.
399 * Minor configure and portability tweaks.
400 Changes since 3.34: * Redesigned `xscreensaver-demo' GUI: it now includes
401 small-preview and per-hack configuration dialogs.
402 * Added three new modes of operation: `One Screen Saver',
403 `Blank Screen', and `Don't Blank' (in addition to the
404 historical `Random Screen Saver').
405 * Configure now defaults to installing the hacks in
406 <prefix>/lib/xscreensaver/ instead of <prefix>/bin/.
407 (Most distros already did it this way.)
408 * New GL hacks, `menger', `engine', `flipscreen3d'.
409 * Made `sierpinski3d' be more colorful.
410 * New versions of `xmatrix' and `nerverot'.
411 * Fixed a bug in `starwars' that made the font be drawn
412 with thin lines in -root mode.
413 * Fixed a bad colormap bug in `crystal' that could make
414 *subsequent* hacks malfunction!
415 * Made `gflux' able to grab screen images (`-mode grab').
416 * Updated `webcollage' for recent search engine changes.
417 * Removed most command-line options to `xscreensaver':
418 just edit the ~/.xscreensaver file instead.
419 * Improved behavior on multi-screen and Xinerama systems:
420 the mouse now stays on the screen where the user left
421 it, and the password and splash dialogs always appear
422 on the screen that has the mouse.
423 * Made the splash dialog use more Gtk-like colors;
424 made it have only two buttons, "Settings" and "Help".
425 * Made `sonar' understand `.ssh/known_hosts2' format
426 files, and be better about stripping out illegal
428 Changes since 3.33: * Turned `memoryLimit' off by default, sigh. Apparently
429 some versions of the GL libraries (appear to) allocate
430 hundreds of megs for every GL program, so `memoryLimit'
431 was causing GL programs to malfunction or crash on
433 * Improved fading on TrueColor XFree86 4.1.x systems.
434 * New GL hack, `circuit'.
435 * Added `fuzz' mode to `decayscreen'.
436 * New version of `whirlygig'.
437 * Added links to `xplanet' and `sphereEversion'.
438 * Fixed rare race condition that could make `sonar' hang.
439 * Fixed potential crash in `speedmine'.
440 * Made `xscreensaver-demo' not crash when imageDirectory
441 was set to a non-existent directory.
442 * Made `xscreensaver-getimage-video' invoke XawTV's
443 `streamer' program better.
444 * Made `phosphor' and `starwars' deal with CR, LF,
445 or CRLF line endings.
446 * Changes for Cygwin compilation environments.
447 * Made `sonar' compile on systems that can't ping.
448 * Configure changes for HPUX 10.20.
449 * Made PAM code work on Red Had 4.2 systems.
450 * Made `xscreensaver-command -deactivate' work when the
451 saver is not active: what that does is reset the idle
452 timer, as if keyboard input had been detected. This
453 was added for the benefit of people writing DVD-playing
454 software: they can now prevent the screensaver from
455 kicking in by sending a -deactivate message once a
456 minute while the movie is playing and not paused.
457 * Various minor portability tweaks.
458 Changes since 3.32: * New hacks, `speedmine' and `whirlygig'.
459 * Sped up `pyro', made the explosions look a bit better.
460 * Added better stars to `glplanet' and `starwars'.
461 * Many internal changes to `webcollage'.
462 * Some new options to `attraction'.
463 * Minor fix to `noseguy' to avoid un-erased pixels.
464 * Rewrote the screen-eraser effects so that they complete
465 in the same amount of time regardless of how slow
466 your X server is (some of them were glacial on servers
468 * Fixed a potential free memory reference that could
469 sometimes cause a crash at startup.
470 * Possibly fixed a problem that could cause the daemon
471 to crash with an X error. I was never able to
472 reproduce this problem, but I think I might have
473 figured out what caused it.
474 * Worked around a problem that caused PAM authentication
475 to fail on some Red Hat 7.x systems.
476 * Added a `memoryLimit' parameter that controls the
477 amount of memory a graphics hack may allocate: if they
478 try to allocate more than this, malloc() will fail
479 (and they will exit or (safely) crash, rather than
480 hogging memory.) Default is 50M.
481 * Made `gnome-help-browser' be the default way to display
482 man pages in `xscreensaver-demo', if running on a
484 Changes since 3.31: * The image-manipulating hacks (`slidescreen', etc.) can
485 now operate on randomly chosen image files from disk,
486 or on frames captured from the system's video input,
487 instead of (or in addition to) manipulating images of
489 * Rewrote `vidwhacker' to use the new image-grabbing
491 * Made fading work on TrueColor XFree86 4.x systems.
492 * Fixed a subtle rendering bug in `atlantis' (the fish
494 * Made `atlantis' have a texture simulating light
495 reflections from the surface of the ocean.
496 * Fixed up label placement in `molecule'.
497 * Better color bars in `xteevee'.
498 * Made `install-strip' not try to strip scripts.
499 Changes since 3.30: * Put in more sensible defaults for DPMS, and updated
500 the documentation to reflect the fact that all your
501 DPMS settings are now belong to xscreensaver.
502 * Fixed the `xscreensaver.spec' file so that `--force'
504 * New versions of `rotzoomer' and `nerverot'.
505 * Fixed an OSF/1 compilation problem in `molecule'.
506 Changes since 3.29: * New hacks, `molecule', `dangerball', and `rotzoomer'.
507 * New version of `gflux'.
508 * Made `gltext' able to display the current time.
509 * Fixed a floating-point-precision problem in `gltext'
510 that sometimes caused horizontal lines to vanish.
511 * Removed the `-window-id' option from the hacks:
512 it never worked right, and was unnecessary.
513 * Made the `starwars' hack use thicker lines, antialias
514 the text, and fade out at the far edge instead of just
516 * Fixed an SHM segment leak in `moire'.
517 Changes since 3.28: * Better rendering of the new logo.
518 * New hack, `gltext'.
519 * Added `-planetary' option to `gears', to draw a
520 different kind of gear system.
521 * Made motion and rotation be smoother in `gears',
522 `glplanet', `moebius', `rubik', and `sierpinski3d'.
523 * Improved coloration in `sierpinski3d'.
524 * Made the GL hacks react to window size changes.
525 * Made most of the GL hacks take a -fps option (like
526 `pulsar' did), so you can use them to benchmark your
528 * Fixed the previous fix to `sonar'.
529 * Minor fix to `nerverot'.
530 Made sonar able to ping hosts on DEC OSF1.
531 * Eliminated a bogus "didn't get enough colors" warning
532 in some of the hacks.
533 Changes since 3.27: * New logo for xscreensaver!
534 * New hacks, `starwars' and `stonerview'.
535 * Made the motion of the bouncing ball in `stairs' be a
537 * Made newly-added screenhacks be added to .xscreensaver
538 automatically: if there are hacks in the app-defaults
539 file that are not also in ~/.xscreensaver, they will
540 be added to the end of the list.
541 * Redid the `Screensaver Options' part of the control
542 panel; xscreensaver now lets you configure your DPMS
544 * Fixed some Makefile problems with non-GL builds.
545 * Fixed detection of MesaGL for version 3.3.
546 * Better workaround to Red Hat 7.0's broken gcc.
547 * Added Sparc Solaris kernel panic to `bsod'.
548 Changes since 3.26: * New hacks: `zoom' and `whirlwindwarp'.
549 * Fixed a free-memory-reference bug in `sonar'.
550 * Better error handling when there are no suitable GL
552 * Added diagnostic dialog when xscreensaver-demo is
553 unable to launch xscreensaver (e.g., when running as
555 * Fixed a bug that caused screenhack argument changes
556 to be ignored when xscreensaver-demo was running as
557 root (if "root" and "nobody" have different home
559 * Made the programs default to ":0" if $DISPLAY is unset.
560 * Made the `-verbose' output include information about
561 which server extensions were supported at compile time.
562 * Worked around Red Hat 7.0's broken gcc 2.96.
563 * Updated default delays on the GL hacks to look better
564 on machines with super-fast 3D hardware.
565 * Install `screensaver-properties-capplet' to work around
566 the usual egregious GNOME lossage.
567 Changes since 3.25: * Added "enabled" checkboxes in the list of hacks in
568 xscreensaver-demo (Gtk version only.)
569 * New hacks `hyperball', `xrayswarm', and `gflux'.
570 * New versions of `nerverot', `galaxy', and `hypercube'.
571 * Small fixes to `phosphor', `shadebobs', `xflame',
573 * Added external helper program `xscreensaver-gl-helper'
574 to figure out which X visual to use for OpenGL
576 * Configure updates for XFree86 4.0, and for BSD.
577 * Made it be more tolerant of bogus /etc/group files.
578 * When installing the PAM config file, first try to just
579 copy an existing "xdm" or "login" config file, so that
580 xscreensaver does authentication in the same way as the
582 Changes since 3.24: * New hack, `nerverot'.
583 * Added BSD kernel panic to `bsod'.
584 * New version of `shadebobs'.
585 * New version of `petri'.
586 * Updated `webcollage' to handle recent Altavista URL
587 format changes; made it search the AP photo gallery.
588 * Revamped command-line options of `sonar' and made it
589 properly handle subnets.
590 * The `bubbles' hack can now trickle up or down the
592 * The `xsublim' hack can now read its text from programs.
593 * Support for GLE version 3 in `extrusion'.
594 * Fixed compilation problems in `maze'.
595 * Fixed a rare crash in `flow'.
596 * Fixes for minor installation problems.
597 Changes since 3.23: * Added `-ignorant' option to `maze' hack.
598 * Updates to `critical', `bsod', `xflame', and `flow'.
599 * Added support for Kerberos 5 (via its Kerberos 4
600 compatibility layer.)
601 * Fixed a bad leak in `xteevee'.
602 * Updated `webcollage' to handle recent Altavista URL
604 * Removed xscreensaver-demo's `Ok' and `Cancel' buttons,
605 since they were confusing people: all changes are now
607 * Made xscreensaver-demo install itself into the Gnome
609 Changes since 3.22: * Fixed some misplaced text fields in the Motif version
610 of xscreensaver-demo; fixed a crash in the Gtk version
611 that would happen if the programs list was empty.
612 * Fixed a recently-introduced bug in `pulsar'.
613 * Made `sierpinski3d' use solid tetrahedrons instead of
615 * Added `-trace' option to `xmatrix'.
616 * Added new hacks `xteevee' and `xspirograph'.
617 Changes since 3.21: * Fixed some bugs in xscreensaver-demo.
618 * Rewrote the Motif version of xscreensaver-demo to
619 match the new Gtk version.
620 * The Athena toolkit is no longer supported.
621 Changes since 3.20: * Tweaked the xscreensaver-demo UI (Gtk only.)
622 * Fixed a few visual selection bugs. I think the proper
623 GL visual should be used with nVidia systems now.
624 * Made the Makefiles obey $install_prefix.
625 * Made the `xscreensaver.spec' file able to generate both
626 GL and non-GL packages simultaneously.
627 Changes since 3.19: * Added new hacks `ripples' and `sierpinski3d'.
628 * Made `xscreensaver-command -exit' be silent when no
629 screen saver was running (instead of complaining.)
630 * Made `webcollage' and `vidwhacker' use `xloadimage'
631 when available (in addition to `xli' and `xv'.)
632 * Improved memory usage in `petri' and gave it a hard
633 cap on how much memory it can allocate.
634 * Added `-watch' option to `xscreensaver-command'.
635 * Made `xscreensaver-demo' come up with the
636 most-recently-run hack selected by default.
637 * Rewrote the Gtk version of `xscreensaver-demo'.
638 It's a lot easier to use now.
639 * Extended the format of the programs list in the
640 .xscreensaver file, for the benefit of the new
641 capabilities of `xscreensaver-demo'.
642 NOTE: you might want to delete your ~/.xscreensaver
643 file and allow it to be re-created! The old one
644 should still work, but xscreensaver-demo won't be as
646 Changes since 3.18: * Fixed gcc dependencies in `bumps' and `ccurve'.
647 * New hack, `extrusion'.
648 * Some of the web sites that `webcollage' was using as
649 its sources changed formats; tweaked it to understand
651 * Added typeahead in the password dialog: if the screen
652 is locked, and you unlock it by typing a character,
653 that key will be automatically inserted in the
654 password dialog (unless it is Return, Enter, Space,
655 or a non-printing key like Shift.)
656 * Made `xmatrix' take a `-small' option, since some
657 folks with tiny screens prefer a smaller font.
658 Changes since 3.17: * New versions of `shadebobs', `lmorph', and `distort'.
659 * Added `ccurve', `blaster', and `bumps' hacks.
660 * Replaced `forest' hack with a rewritten version.
661 * Worked around a Xinerama server bug.
662 * Fixed a bug I introduced in 3.10 that caused some
663 hacks to print out superfluous warnings about not
664 having gotten enough colors.
665 * Made `sproingies' obey the `-delay' option.
666 * Fixed a portability bug in `shadebobs'.
667 * Made `webcollage' and `vidwhacker' use `xli' in
668 preference to `xv', if it is available.
669 * Added a new source of images to `webcollage'.
670 * If running under KDE, xscreensaver will add itself to
671 KDE's list of screensavers (via xscreensaver.kss.)
672 * Improved detection of GL libraries.
673 * Made the password dialog include the date and time.
674 Changes since 3.16: * New version of `webcollage' -- deals better with
675 corrupted images, and can use an http proxy.
676 * New hack, `xsublim' (run it in the background,
677 rather than adding it to the programs list.)
678 * The xscreensaver daemon was leaking a file descriptor
679 each time you edited your .xscreensaver file. Fixed.
680 Changes since 3.15: * New version of `shadebobs'.
681 * Improved image selection in `webcollage', and sped it
683 * Made configure find the right version of perl.
684 * Rewrote the CGI part of `webcollage'.
685 * `make clean' was deleting some things it shouldn't.
686 * Fixed a typo in the default programs list.
687 Changes since 3.14: * Added `webcollage' and `shadebobs' hacks.
688 * Added a `-stdout' arg to `vidwhacker' so that it can
689 be used in a pipeline.
690 * Made `petri' use less memory.
691 Changes since 3.13: * Various improvements to the Gtk port.
692 * Turned off PAM by default on Solaris, since PAM seems
693 generally to be misconfigured out-of-the-box.
694 * Made the `--without-gtk' configure option work.
695 * Made configure check the Gtk version number, since it
697 * Fixed a bug in the code that attempted to prevent
698 changes of screen resolution while the screen is
700 * Fixed a race condition in `xscreensaver-demo' that
701 could cause an X error at startup.
702 * Added `-transparent' option to `deluxe'.
703 * Added `petri' hack.
704 Changes since 3.12: * Ported `xscreensaver-demo' to Gtk.
705 * Made it possible to build Motif, Gtk, and Athena
706 versions of `xscreensaver-demo' in the same directory
707 without reconfiguring.
708 * Made `xscreensaver-demo' chase symlinks before writing
709 the .xscreensaver file, so that if .xscreensaver is
710 itself a symlink, the underlying file will be replaced
712 * Some Makefile and configure tweaks for Solaris and
714 * Made it possible to set the fire color in `xflame'.
715 * Made transparency work in TrueColor (for `goop' and
717 * Fixed a multi-head bug introduced by the virtual
719 Changes since 3.11: * Made it so that you can't scroll the screen while the
720 lock dialog is up (with XFree86 virtual viewports.)
721 * Fixed a bug in `flag' that caused bob's chin to get cut
722 off after a few iterations.
723 Changes since 3.10: * Made `xjack' be black-on-white-ish, so that it looks
724 less like a computer screen and more like the
725 typewritten paper it's supposed to be.
726 * New version of `pulsar'.
727 * Fixed Solaris compilation problem in `phosphor'.
728 * Made xscreensaver notice XFree86's virtual root window
729 hack, so that if the X server's root window is larger
730 than the monitor's displayable resolution, the screen
731 saver will limit itself to the area that actually
732 appears on the screen.
733 * Made the xscreensaver daemon do a better job of
734 picking the visual class that should be used for GL
735 programs. Less user intervention should be needed
736 now: you can use the logical visual name `GL' instead
737 of having to figure out by hand which one to use.
738 * Oops, the visual was defaulting to "best" instead of
739 "default", because the .xscreensaver file was not being
740 loaded quite early enough.
741 * Made configure figure out how to build icmp ping
742 support into the `sonar' hack automatically.
743 * Made warnings about not being able to read shadow
744 passwords not be printed if compiled with PAM support.
745 * Improved PAM startup diagnostics.
746 * Worked around the Solaris PAM bug that was causing
747 crashes there, so now PAM is turned on by default.
748 * Made configure detect the number of arguments that
749 pam_strerror() takes, since on Linux, this apparently
750 changed between 2.0 and 2.2, sigh.
751 * Made the /proc/interrupts kludge look for "PS/2 Mouse"
752 as well as "keyboard".
753 * Made xscreensaver notice when there has been a sudden
754 large jump in wall-clock time, and if so, lock right
755 away, instead of waiting for "lockTimeout" to expire
756 first. (Laptops need this for safer recovery from
758 * Added `-throttle' option to `xscreensaver-command'.
759 Changes since 3.09: * Added `phosphor', `xmatrix', and `pulsar' hacks.
760 * Fixed a bug in the color allocator that sometimes
761 caused `starfish' to fall back to monochrome.
762 * Reduced the amount of code that runs before root
763 privileges are disavowed: "normal" and "shadow"
764 passwords now do some initialization as root, but the
765 PAM and Kerberos authorization schemes will be
766 initialized while running as "nobody". Supposedly
767 this closes a potential security hole when using
769 * Added some more sanity checking to configure.
770 Changes since 3.08: * Added `compass', `squiral', `xflame', `wander',
771 `spotlight', and `critical' hacks.
772 * Added some new modes to `decayscreen'.
773 * Made `deluxe' work in monochrome.
774 * Generalized usage of the Double-Buffer server extension
775 in several hacks (`compass', `deluxe', `interference',
776 `kumppa', and `moire2'.)
777 * Fixed another visual-depth problem in `rd-bomb'.
778 * The screen saver will now defer blanking if neither
779 the keyboard nor the mouse could be grabbed. Instead,
780 it will just try again in a few minutes. This fixes
781 a bad interaction between xscreensaver and programs
782 like VMware that hold the mouse and keyboard grabbed
784 * Added a new erase mode (expanding spiral.)
785 Changes since 3.07: * Fixed some bugs in my port of `t3d'.
786 * Added `penetrate' and `deluxe' hacks.
787 * When linking against Motif 2.x, also link against XPM.
788 * Added support for using /proc/interrupts for idle
789 detection on Linux. Now xscreensaver shouldn't kick
790 in when the user is active on a non-X virtual console.
791 * Upgraded to autoconf 2.13.
792 Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
793 in properly; check for _Xsetlocale in -lXintl.)
794 * Portability fixes for sonar.c.
795 * Fixed a compilation problem when you have GL but don't
797 * Made configure notice when MesaGL requires -lpthread.
798 * Made `flame' ignore SIGFPE (not sure if this is the
799 right fix; it seems only to be needed on FreeBSD.)
800 * Kludged `rd-bomb' work on visuals that are of depth 24
801 but that *do not* support pixmaps of depth 32.
802 * Fixed `halo' to work properly in TrueColor.
803 * Changed `xscreensaver.spec' to install the hacks in
804 /usr/X11R6/lib/xscreensaver/ by default, since that's
805 where recent Red Hat distributions put them.
807 * Updated versions of `crystal', `hopalong', and `flow'
809 * Imported `demon' and `loop' modes from xlockmore.
810 Changes since 3.05: * Oops, the "default-n" visual descriptor was broken;
811 it was always installing a colormap if the
812 `installColormap' preference was set, meaning that
813 `xearth', `xv' and friends were using the wrong
814 colors on 8-bit systems.
815 * Turned off HAVE_PING in `sonar', since it compiles
816 on some Linux systems, but not others of similar
818 Changes since 3.04: * Fixed an off-by-1 in `distort'.
819 * Added `sonar' hack.
820 * New version of `glplanet' (with stars.)
821 * Made all hacks exit when you type `q' or `ESC' at them,
822 and made them obey the WM_DELETE_WINDOW ClientMessage.
823 * Fixed a nonfatal buffer overrun in lament (note:
824 lament still doesn't work with MesaGL 3.0: it dies in
825 lambda_textured_triangle1(), which is Mesa's bug, not
827 Changes since 3.03: * Added an `xscreensaver.spec' file, to make it easier
828 for other folks to generate RPMs.
829 * Made the password code work on HPUX in the situation
830 where: ``enhanced security'' is available; but not
831 used; but the user typed a password more than 8
832 characters long anyway. FTSOHPUX.
833 Changes since 3.02: * Made locking work when passwd aging is enabled.
834 * Added support for PAM (Pluggable Authentication
835 Modules.) It is still turned off by default, though,
836 since it doesn't seem to work on Solaris 2.6, and has
837 been behaving erratically on Red Hat 5.1.
838 * Made each possible authentication method be tried in
839 turn until one succeeds; this means that Kerberos is
840 being used, we will first check Kerberos, and if that
841 fails, will then consult the local password file.
843 * Save and restore the bits under the passwd dialog,
844 to avoid leaving a black rectangle behind when
845 unlocking is cancelled.
846 Changes since 3.01: * Not everyone has sys/select.h, sigh...
847 Changes since 3.00: * Some fixes to `reflect'.
849 * Made it log unsuccessful attempts to unlock the screen
851 * Fixed a bug where `xscreensaver-demo' could be seeing
852 a different programs list than `xscreensaver' did.
853 Changes since 2.34: * The xscreensaver daemon no longer links against Motif
854 or Athena: demo-mode and the preferences panel are no
855 longer built in to the daemon, but are now handled by
856 an external program, `xscreensaver-demo'.
857 (I decided that this, along with the recent addition
858 of the `.xscreensaver' config file, justified bumping
859 the version number to 3.00, since this is a fairly
860 major architectural change.)
861 * Lines in the `*programs' resource may now begin with
862 the character "-", meaning "don't run this hack."
863 In this way, it's possible to disable a hack without
864 throwing away the information about it (making it
865 easier to change your mind later.) Eventually the
866 preferences/demo mode GUI should represent this as a
867 checkbox or something.
868 * Fixed a short race condition where it was possible for
869 xscreensaver to die with a BadWindow error if it was
870 blanking the screen just as another window was being
872 * Made it possible to disable specific modes in `bsod'.
873 Changes since 2.33: * Fixed a bug that was making `pipes' generate way too
874 many valves. Made the viewpoint in `pipes' be selected
875 randomly instead of always being -10 degrees.
876 * Fixed a bug in the XSHM code, in the case where the
877 server supports the XSHM extension but is not the same
878 machine as the client.
879 * Made `rd-bomb' default to taking up the whole screen.
880 * Made it not try to do fading/unfading if no PseudoColor
882 * Initial attempt at supporting VT-locking (doesn't work
884 * Eliminated the `captureStdout' resource; now
885 `captureStderr' controls both streams.
886 * Added `-capture-stderr' and `-no-capture-stderr'
887 command-line arguments.
888 * Added `glplanet' hack.
889 * When a hack is selected with `xscreensaver-command
890 -select', that hack will be used until further notice
891 (until the saver turns off, or another activation
893 Changes since 2.32: * Made `xscreensaver-command' print error messages:
894 the xscreensaver daemon now responds to ClientMessage
895 events by writing a response message on a window
896 property, instead of just writing to its stderr.
897 * Made the ~/.xscreensaver file be automatically reloaded
898 when the file date changes.
899 * The password dialog and splash screen no longer depend
900 on Motif or Athena. This should clear up a number of
901 focus problems, and is the first step on the path
902 toward moving all of the Motif/Athena/whatever code
903 out of the xscreensaver daemon, and into external
905 * Don't complain about LessTif 0.86 any more, since the
906 new password dialog makes that problem go away.
907 * Configure tweaks for Irix 6.5, SunOS 5.something.
908 * New `-reflect' option to `distort'.
909 Changes since 2.31: * Added reading and writing of a ~/.xscreensaver file,
910 so that the Preferences panel can save its settings.
911 * New version of `rubik'.
912 * Added `-select N' argument to `xscreensaver-command'.
913 * Oops, left out some of the `bubbles3d' files...
914 Changes since 2.30: * The cursor was invisible in the password dialog. Fixed.
915 * Made configure warn against MesaGL 2.6.
916 * Fixed X error at startup when using non-default visual.
917 * New version of `crystal', `ant', and `atlantis' from
919 * New hack, `bubble3d'.
920 * Added some new modes to `bsod'.
921 Changes since 2.29: * Changed the order in which -lSM and -lICE are linked
922 to be after Motif instead of before (Lesstif on Irix
924 Changes since 2.28: * Work around a bash bug in configure.
925 * Tweaked HPUX paths again. FTSOHPUX.
926 * Made configure recommend against LessTif 0.86, due
927 to a bug in that version that causes a security hole
928 in the screen locking code. LessTif 0.87 will fix it.
929 * Made all of the `--with' options to `configure' accept
930 a directory option as well (so that --with-motif=/FOO
931 will add -I/FOO/include -L/FOO/lib). I believe this is
932 the Configure Party Line of how do to such things.
933 * Fixed a bug where the mouse was left un-grabbed
934 after the first time the graphics hack was changed
935 (simplified all of the mouse-grabbing logic.)
936 * Maybe possibly perhaps made `vidwhacker' really not
937 leave stray xv windows around. This time for sure.
938 * Added a new erase mode (random dots fizzling out.)
939 * Added `-prefs' argument to `xscreensaver-command',
940 that brings up the Preferences dialog directly (it
941 seems that nobody ever noticed the `Preferences' button
942 on the Demo Mode dialog, maybe this will help.)
943 * Added a splash screen. Turn it off with *splash:false.
944 Changes since 2.27: * Better macsbug text in `bsod'.
945 * New version of `distort' with many new modes.
946 * Plugged a leak in `coral'.
947 * Tweaked configure for HPUX.
948 * Removed some compiler warnings.
949 * More consistent usage of stderr versus stdout.
950 * More diagnostics should an X error occur.
951 * Fixed a possible crash in SGI-specific unfading code.
952 Changes since 2.26: * Improved version of `distort'.
953 * Made `lament' compile against OpenGL 1.0 (though it
954 still requires 1.1 to work properly.)
955 * Updated my email address and home page.
956 Changes since 2.24: * Improved motion in `rd-bomb'.
957 * Added XSHM (shared memory extension) support to the
958 `distort', `interference', `moire', `rd-bomb', and
959 `swirl' hacks, which speeds them up a bit.
960 * Added `lament' hack.
961 Changes since 2.23: * Tweaked the order of the -L options again.
962 * Cleaned up configure's `--help' message.
963 * Added `kumppa' hack.
964 * Smarter maze-solving algorithm in `maze'.
965 * Took `xlyap' out of the default list of hacks, since
966 it's just incredibly buggy (and slow.) Maybe someday
967 someone will fix it...
968 * Added `distort' hack, but didn't add it to the default
969 list (yet) because it's still too slow.
970 * Made the Athena demo dialog look more like the Motif
971 version; it has a text-entry field now, too.
972 * Made the Athena password dialog echo asterisks, like
973 Motif does, instead of using a flyspeck font.
974 * Some random configure tweaks.
975 * Added a `timestamp' resource that makes the `-verbose'
976 messages include the time at which they were printed.
977 Changes since 2.22: * The fix for SGI's ``scheme'' nonsense broke things, and
978 let the user's "*background" resource show through.
979 Fixed it in a different way.
980 Changes since 2.21: * Added support for the DPMS server extension (Display
981 Power Management System.)
982 * Made configure advertize the `--enable-subdir' option a
983 little more, since that seemed to cause some people
984 stress. Also, made that directory be built into the
985 xscreensaver executable, as a hardcoded prefix to
986 $PATH. (Might help, shouldn't hurt.)
987 * Made configure prefer the two-arg gettimeofday to the
988 one-arg version, since AIX doesn't have any prototypes.

997 "active since..." and "inactive since..." which a lot
998 of people interpreted as meaning the opposite of what
1000 * Improved some error messages, in the hopes of making
1001 the distinction between the xscreensaver and
1002 xscreensaver-command programs more obvious.
1003 * Rewrote (and reorganized) parts of the xscreensaver and
1004 xscreensaver-command manual pages.
1005 * Renamed xscreensaver's `-lock' command-line option to
1006 be `-lock-mode', to avoid confusion with the `-lock'
1007 option to xscreensaver-command, which does a totally
1009 * Removed xscreensaver's `-demo' command-line option for
1010 a similar reason; use `xscreensaver-command -demo'
1012 * Disabled SGI's ``scheme'' nonsense in a better way than
1013 fully-qualifying the background colors in every single
1015 * Fixed some other minor cosmetic problems when *sgiMode
1017 * Fixed an X error in `bsod -root' (how ironic...)
1018 Changes since 2.19: * Fixed a bug that caused the mouse to sometimes not be

1034 * Added `bsod' hack.
1035 * Added some new modes to `vidwhacker'.
1036 Changes since 2.16: * Added a -window-id argument to most hacks, so that they
1037 can draw on arbitrary externally-provided windows.
1038 * Synched with xlockmore 4.11a01.
1039 * Added `flow' hack.
1040 * Added `atlantis' GL hack.
1041 * Renamed `puzzle' hack to `jigsaw', since xlock already
1042 had a different mode called `puzzle'.

1044 being used (requires -lXp now, sigh...)
1045 Changes since 2.15: * Made `flag' able to do XPM images.

1061 * Changed subprocess handling to use sigaction() instead
1062 of signal() if it's available (this is necessary for
1063 SCO but should work fine on other systems too.)
1064 * Various other tweaks.
1065 Changes since 2.13: * Better fix for the Motif drag-and-die lossage.
1066 * Put in some kludges to work around a LessTif bug.
1067 * XScreenSaver is known to work with LessTif 0.82 now.
1068 * Made fading work on high-end SGI video hardware.
1069 * Fixed another SGI-specific bug in screen grabbing;
1070 will the madness never cease?

1072 Changes since 2.12: * Made `decayscreen' do directions other than down.

1083 wily, malicious cracker must have slipped in.

1088 * Added `puzzle' hack.
1089 * Added `xlyap' hack.
1090 * Added `default-n' as a visual name, so that one can

1092 certain poorly-behaved hacks (like xv.)
1093 * Added support for grabbing frames of external video
1094 (on SGI) to the screen-grabbing hacks (decayscreen,
1095 slidescreen, slip, blitspin, and puzzle.)
1096 * Improved look of tiles in `slidescreen'; fixed its
1097 color allocation problem.
1098 Changes since 2.10: * Tweaked `blitspin', added it to the default list.
