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 2.4 and MacOS X 10.4.0

39 ===============================================================================
41 Changes since 5.06: * Xinerama/RANDR tweaks for old-style multi-screen.
42 * Fixed the bouncing ball in `stairs'.
43 * `flipflop' can load images onto the tiles.
44 * Improved layout of the preferences dialogs: they
45 should all now be usable even on ridiculously tiny
47 * MacOS preferences text fields now prevent you from
48 entering numbers that are out of range.
49 * Added "Reset to Defaults" button on X11.
50 * Added relevant Wikipedia links to many of the screen
52 * All hacks support the `-fps' option, not just GL ones.
53 * The `-fps' option now shows CPU load.
54 * Added bumpy skin and cel shading to `skytentacles'.
55 * Added the missing Utah Teapotahedron to `polyhedra'.
56 * `blitspin' works with color images on OSX now.
57 * Added transparency to `stonerview'.
58 Changes since 5.05: * Xinerama/RANDR fixes: this time for sure. It should
59 now work to add/remove monitors or resize screens at
61 * New hack, `skytentacles'.
62 * New version of `gleidescope'.
63 * Added the `-log' option to the xscreensaver daemon,
64 since a truly shocking number of Linux users seem to
65 have no idea how to redirect output to a file.
66 * Added `-duration' arg to most image-loading hacks,
67 so that they pick a new image every few minutes.
68 * Added an ATM crash to BSOD.
69 Changes since 5.04: * New hacks, `cubicgrid', `hypnowheel', and
70 `lcdscrub' (which isn't really a screen saver).
71 * Updates to `m6502' and `gears'.
72 * Fixed double-buffering problems in `cubestorm' and
74 * Better handling of horizontal scroll wheels.
75 * Attempt to work around latest Xinerama braindamage:
76 if the server reports overlapping screens, use the
77 largest non-overlapping rectangles available.
78 * Don't warning about receipt of bogus ClientMessages,
79 since Gnome's just never going to stop sending those.
80 * Worked around MacOS 10.5 perl bug that caused the
81 text-displaying hacks to fail on some systems.
82 * Hopefully fixed font-related System Preferences crashes
84 * The recent PAM changes broke the "Caps Lock" warning
85 in the password dialog, the failed login warnings, and
86 syslogging. Fixed all that.
87 Changes since 5.03: * Fixed a possible crash in the unlock dialog (more
88 fallout from the recent PAM changes...)
89 * New hacks, `moebiusgears', `abstractile', and
91 * Rewrote `gears' to use better (involute) gear models,
92 and to be more random.
93 * Minor updates to `cwaves', `voronoi', `deco',
94 `glcells', `rd-bomb', `fireworkx' and `webcollage'.
95 * `pong' can now display the current time as the score.
96 * `xmatrix -mode pipe' works better.
97 * Minor tweaks for compilation on MacOS 10.5.0.
98 Changes since 5.02: * New hacks, `cwaves', `glcells', `m6502', and `voronoi'.
99 * Minor fixes to `bsod'.
100 * Fixed possible crash with PAM USB-dongle auth.
101 * Updated `webcollage' to track recent Google Images
103 Changes since 5.01: * Reworked PAM code to support fingerprint readers, etc.
104 * Ported 'webcollage' to OSX.
105 * Added OSX 10.2 and 10.3 kernel panics to `bsod'.
106 * Fixed a Xinerama crash when changing the screen count.
107 * New blobbier `mirrorblob'.
108 * Minor updates to `lisa', `bsod', `ifs', `hypertorus',
109 `polytopes', `circuit', `endgame', `crackberg',
110 `flipflop', `flipscreen3d', `fliptext', and `carousel'.
111 * Enabled multi-threaded OpenGL on OSX.
112 Changes since 5.00: * Backed out recent locale-related changes, since they
113 broke far more things than they fixed.
114 * Fail gracefully with ridiculously small window sizes.
115 * `xflame' and `flag' ignore bitmap option on MacOS.
116 * `speedmine' prefs work on MacOS.
117 * Better explosions in `boxed'.
118 * More dynamic motion in `sproingies'.
119 * More options in `flipflop'.
120 * Minor updates to `topblock'.
121 * Various other minor fixes.
122 Changes since 4.24: * Ported to MacOS X! (10.4.0 or newer)
123 * API change: instead of providing a single screenhack()
124 function that does not return, screen savers using the
125 screenhack.h framework must now provide "init" and
126 "draw one frame" functions instead. All bundled savers
127 have been updated; third-party patches will need work.
128 * All image-loading happens asynchronously.
129 * xscreensaver-getimage-file caches the contents of the
130 image directory for a few hours, so consecutive runs
131 won't have to re-list the whole directory tree.
132 * New hacks, `topblock' and `glschool'.
133 * Removed `xteevee' (superceded by `xanalogtv').
134 * Added variable-sized puzzle pieces to `jigsaw'.
135 * Changes to the defaults and command-line options of
136 many hacks to make the .xml files more consistent.
137 * Reap zombies in `glslideshow' and `carousel'.
138 * `sonar' works without setuid on OSX (dgram icmp).
139 * `xmatrix -mode pipe' displays the text of a subprocess.
140 * `endgame' has higher resolution chess-piece models.
141 * `webcollage' takes a -directory option to get images
142 from a local directory.
143 * The RPM spec file no longer auto-restarts xscreensaver
144 when a new version is installed. Restart it manually.
145 Changes since 4.23: * New versions of `cube21', `glsnake', `celtic'.
146 * Backed out a DPMS-related patch that cause desktop
147 flickering with some X servers.
148 * Fixed startup crash in getgroups() when running setuid.
149 * Default to not displaying stderr on the saver window.
150 * Fixed bad free() in "Documentation" button.
151 * Don't try to run hacks that aren't installed.
152 * Minor fixes to various XML config files and man pages.
153 Changes since 4.22: * New hacks, `glhanoi', `cube21', `timetunnel',
154 `juggler3d', and `celtic'.
155 * New versions of `tangram', `webcollage', `hypertorus',
156 `polytopes', and `ripples'.
157 * `sonar' is now quiet about unresolvable hosts.
158 * Minor corrections to BASIC code in `apple2'.
159 * xscreensaver-demo now provides an RPM clue when none
160 of the hacks seem to be installed.
161 * Don't install `ant' by default, since there is some
162 Java tool of that name, which was causing confusion.
163 And also it's boring.
164 * Made screen grabbing work again on MacOS 10.4.2.
165 * No longer prints bogus warnings about ClientMessages
166 intended for the window manager.
167 * Ignore unprintable characters in passwd entry field.
168 * Fixed yet another cross-host-display image-loading
170 * `xscreensaver-command -watch' and `-time' now work
172 Changes since 4.21: * Fixed a bug in the new mouse-motion code that caused
173 the screen to never blank on multi-head non-Xinerama
175 * New hacks, `interaggregate', `antmaze', `tangram',
177 * Minor tweaks to `fiberlamp', `ifs', `slidescreen',
178 `zoom', `sonar', `fireworkx', `whirlwindwarp',
179 `bubble3d', and `rd-bomb'.
180 * Added motion blur to `blinkbox'.
181 * `bsod' now includes Longhorn's "RSOD", and OS/2.
182 * Fixed `-wireframe' usage in most hacks and man pages.
183 Changes since 4.20: * New hack: `fliptext'.
184 * Changed default configure installation directories:
185 /usr/bin/ for xscreensaver, etc.;
186 /usr/libexec/xscreensaver/ for hacks;
187 /usr/share/xscreensaver/config/ for xml files.
188 * All the text-manipulating screen savers can have their
189 text source configured via `xscreensaver-demo' now.
190 * xscreensaver.spec now builds three RPMs:
191 base (no hacks); extras (2d hacks); and gl-extras.
192 * Added `-program' and `-front' option to `gltext'.
193 * Added `-shells' to `molecule'.
194 * Fixed text-alpha glitch in `carousel'.
195 * New `pacman': the ghosts can be killed now.
196 * Fixed a bug in screen-grabbing GL hacks where images
197 would be tiled instead of scaled on machines that
198 can't do large textures.
199 * `webcollage' can hit Flickr now.
200 * New (rewritten) implementation of `ifs'.
201 * The unlock dialog can be made to have a "New Login"
202 button that will run `gdmflexiserver'. Experimental!
203 * Fixed non-ASCII display bug in `starwars'.
204 * Configure finds a default for imageDirectory.
205 * "xscreensaver-command -lock" now works even if
206 in "screensaver disabled" mode.
207 * If a bad password is typed while CapsLock is on, the
208 unlock dialog says "CapsLock?" instead of "Sorry".
209 * Mouse motion only counts as activity if the mouse moved
210 more than 10 pixels (so the screen won't unblank every
211 time you bump your desk.)
212 * New mode option "random-same": if you have multiple
213 monitors, this will run the *same* randomly chosen
214 hack on each screen, instead of different ones on each.
215 Changes since 4.19: * New hacks, `fiberlamp', `boing', `boxfit', and
217 * Rewrote `glslideshow' again: should be faster now.
218 * Sped up loading of images in GL programs.
219 * `starwars' uses texture-mapped fonts now.
220 * New `bsod' modes: tru64, hppa, and nvidia.
221 * Updates to `webcollage', `juggle', `pinion',
222 `fireworkx', `sonar', `extrusion', `substrate', and
224 Changes since 4.18: * New hacks, `substrate', `intermomentary', `fireworkx',
226 * New version of `flow'.
227 * Made /proc/interrupts work again on Linux 2.6.
228 * Made `analogtv' not hog the CPU.
229 * Made analogtv-based hacks work properly on PPC/ARM.
230 * Fixed a bad memory leak in `piecewise'.
231 * Minor updates to `sonar', `molecule', `glmatrix',
232 `galaxy', and `webcollage'.
233 * Removed support for GTK 1.x (everyone uses 2.x now.)
234 Changes since 4.17: * Oops, pay no attention to the man behind the curtain.
235 Changes since 4.16: * New hacks, `anemotaxis' and `memscroller'.
236 * Fixed a bad bug that caused `vidwhacker' to never die.
237 * Fixed normals and lighting in `polyhedra'.
238 * Don't reuse the window when changing hacks (to work
239 around bugs in some GL implementations.)
240 * Made `xscreensaver-getimage-file' skip thumbnail-sized
242 * Fixed endian problem in `barcode' on non-x86.
243 * Updates to `webcollage', `apple2', `fuzzyflakes',
244 `atunnel', and `pacman'.
245 * Timing tweaks to `bubble3d', `bouncingcow', `engine',
246 `gltext', `lavalite', `molecule', `spotlight',
247 `sballs', `boxed', `blinkbox', and `circuit'.
248 * Configure updates for Fedora core 2 / xorg 6.7.0.
249 * Compile without warnings under gcc 3.3.3.
250 * I give up: don't blank or lock the screen if we can't
251 get a keyboard grab. In that case, both choices are
253 Changes since 4.15: * New hacks, `polyhedra', `fuzzyflakes', `antinspect',
255 * Minor updates to `webcollage', `bsod', `endgame',
256 `antspotlight', `xmatrix', and `glmatrix'.
257 * Added support for the RANDR (Resize and Rotate)
258 extension to detect when the size of the desktop has
259 been changed while xscreensaver is already running.
260 * Possibly-futile attempt to work around "rdesktop"
262 * Made `xscreensaver-getimage -file' still work even if
263 imageDirectory is unset.
264 * Convert Latin1 to ASCII in `starwars' and `phosphor'
265 (since the GLUT font only has ASCII glyphs.)
266 * Fixed randomization in `noof'.
267 * Added "GetViewPortIsFullOfLies" preference to work
268 around longstanding XFree86 bug #421.
269 * Made `sonar' subnet pinging work properly on bigendian
270 machines (e.g., PPC.)
271 Changes since 4.14: * New hacks, `wormhole', `mismunch', `noof', and
273 * `phosphor' and `apple2' include vt100 emulators now:
274 this means you can do "phosphor -program top", or
275 can use either program as an xterm replacement:
276 "apple2 -text -fast -program 'xemacs -nw'".
277 * `analogtv' (and related) fill the screen better.
278 * The '-gradient' option works in `atlantis' now.
279 * Minor updates to `blinkbox', `queens', `endgame',
280 `glmatrix', `mirrorblob', `blocktube', and `molecule'.
281 * Integrated SuSE's "external passwd helper" support.
282 * Marginally better /tmp handling in various programs.
283 * Updated config defaults for xplanet 1.0.3.
285 Changes since 4.13: * New hacks, `fontglide', `apple2', `xanalogtv', `pong',
286 `gleidescope', `mirrorblob', and `blinkbox'.
287 * New version of `glsnake' (with many more models.)
288 * Another Windows crash in `bsod'; also HVX/GCOS6/TPS6.
289 * New version of `endgame'.
290 * Screen grabbing works on MacOS X.
291 * Various minor fixes.
292 Changes since 4.12: * On Xinerama systems, xscreensaver now runs one hack on
293 each monitor (just like in "real" multi-head mode)
294 instead of running one hack stretching across all the
295 screens. Note that for this to work with any 3rd party
296 screensavers, they must update their "vroot.h" file.
297 * `webcollage' and `vidwhacker' display images using
298 `xscreensaver-getimage' now.
299 * Added `ljlatest' script for use with `starwars' and
301 Changes since 4.11: * New GL hacks, `flipflop', `antspotlight', and
303 * Added VMS to `bsod'.
304 * Compile without warnings in "gcc -pedantic".
305 * Updates to `webcollage' and `queens'.
306 * Fixed a bug that could cause PAM to hang.
307 Changes since 4.10: * New hacks, `hypertorus', `cubestorm', `glknots',
308 `blocktube', and `glmatrix'.
309 * Updates to `cloudlife', `engine', `xmatrix', and
311 * Rewrote `glslideshow': it should work on somewhat
312 wimpier video cards now.
313 * Various portability tweaks.
314 Changes since 4.09: * New hacks, `cloudlife' and `klein'.
315 * Added Apple ][+, HPUX, and OS/390 sessions to BSOD.
316 * Added some Matrix Reloaded text to `xmatrix'.
317 * Updates to `webcollage', `eruption', `jigglypuff',
318 `metaballs', and `endgame'.
319 * Completely ignore the `memoryLimit' setting now,
320 since it was still causing people GL grief.
321 * Various minor fixes.
322 Changes since 4.08: * New hacks, `flyingtoasters', `bouncingcow',
323 `jigglypuff', and `glslideshow'.
324 * More models in `engine'.
325 * Rewrote `xscreensaver-getimage' to remove reliance on
326 external image loaders (xv, chbg, xloadimage, etc.)
327 and to reduce flicker when loading files.
328 * Made `gflux' and `flipscreen3d' be mouse-spinnable.
329 Changes since 4.07: * New hacks, `atunnels' and `piecewise'.
330 * Physics improvement in `fluidballs'.
331 * Various fixes for XDarwin systems (X11 on MacOS X.)
332 * Added -clock option to `barcode'.
333 * Minor fixes to `endgame', `flurry', `flipscreen3d',
335 Changes since 4.06: * New hacks, `flurry', `metaballs', `eruption',
336 `popsquares', and `barcode'.
337 * Minor updates to `maze' for high density mazes.
338 * Added double buffering to `fluidballs' and `whirlygig'.
339 * Bug fixes for running xscreensaver to a remote XFree86
340 display (which nobody would ever do...)
341 * Updated `webcollage' (faster Alta Vista searching.)
342 * Updated `glplanet' so the sun sets in the west.
343 * Updated `sproingies' with smooth, unsegmented surfaces.
344 * Fixed Perl version-sensitivity in
345 `xscreensaver-getimage-file'.
346 * Fixed GTK2 scrolling bug in `xscreensaver-demo'.
347 Changes since 4.05: * New hack, `glblur' (disabled by default, since it
348 requires fast OpenGL texture support.)
349 * New hack, `halftone'.
350 * Updates to `endgame', `queens', `bumps', `glplanet',
351 `engine', and `circuit'.
352 * New version of `menger' that uses far fewer polygons.
353 * Fixed minor bug in `critical' that could cause some
354 bogus X servers to crash.
355 * Better labels in `molecule': the labels now appear to
356 be attached to the atoms, instead of floating in front
358 * Fixed bug that could rarely cause GL hacks to fail to
359 double-buffer (causing intermittent flickering.)
360 * Fixed a relative-URL-parsing bug in `webcollage'.
361 * Fixed a bug that (sometimes) caused the window manager
362 close box to kill `xscreensaver-demo' with a crash
363 instead of a graceful exit.
364 * Updated xscreensaver.pam to the Red Hat 7.3 way.
365 * More Gnome2-related configure crap.
366 * Updated to latest `config.guess' and `config.sub'.
367 * Fixed occasional core dump in `distort'.
368 * Added a Linux fsck failure and kernel panic to `bsod'.
369 * Added MacOS X kernel panic to `bsod'.
370 * Fixed a bug in `bsod' (all bsod bugs are ironic.)
371 * Fixed a bug that caused `xscreensaver-gl-helper' to
372 print a nonsense visual ID with some versions of
373 `printf': this could cause GL programs to display
374 incorrectly (e.g., flickery.)
375 Changes since 4.04: * More `configure' tweaks to try and get things working
376 on systems that both Gtk 1.x and 2.x installed.
377 * New hack, `endgame'.
378 * Minor updates to `gltext'.
379 Changes since 4.03: * Support for GTK 2.x / GNOME 2.x.
380 * The `configure' script will now use `pkg-config' if
381 you have it, in preference to `gtk-config', etc.
382 * New hacks, `lavalite', `queens', and `anemone'.
383 * Minor updates to `spheremonics', `gltext', `xmatrix'.
384 * You can use the mouse to manually spin most of the GL
385 hacks now (when they are displaying in a window.)
386 * Fixed a bug in `webcollage' (due to recent Alta Vista
387 url changes) that was causing it to try and load
388 incorrect image URLs.
389 * Made `xscreensaver-getimage' use gdk_pixbuf if it is
390 available: this means that those hacks that load images
391 will no longer rely on "xv", "xloadimage", etc. This
392 will close a race condition that could sometimes cause
393 your desktop background to be changed; and also makes
394 it possible for those programs to operate on image
395 files when running in windowed mode.
396 * `webcollage' can now be used in conjunction with
397 `driftnet' to display images snooped from your local
398 ethernet instead of obtained from search engines.
399 * Added man pages for all the hacks that didn't have
401 Changes since 4.02: * New hack, `spheremonics'.
402 * Minor updates to `webcollage', `cage', `moebius',
403 `morph3d', `boxed', `circuit', and `helix'.
404 * `pulsar' and `extrusion' can now load texture JPEGs.
405 * `rubik' now does non-square cubes.
406 * `fluidballs' now does various sizes of balls.
407 * `menger' and `sierpinski3d' now also show polygon
409 * `molecule' displays real subscripts in the formulae.
410 * GTK internationalization/localization support.
411 * Better detection of the various versions of libxml.
412 * Upgraded to autoconf 2.53 (from 2.13.)
413 Changes since 4.01: * Plugged a few minor leaks in `xscreensaver' and
415 * New hacks, `cubenetic' and `fluidballs'.
417 * Fixed sphere projection error in `glplanet'; installed
418 a better image of earth.
419 * Added Win2K and MacOS 1 crashes to `bsod'.
420 * Put back previous (better) version of `forest' that
421 was accidentially downgraded in the last release.
422 * New version of `bumps'.
423 * Made FPS computation in GL hacks more efficient: it
424 will influence the results less, thus resulting in
425 higher (but more accurate) reported frame rates.
426 Changes since 4.00: * New hacks: `twang', `glsnake', `boxed', `sballs',
428 * New hacks `apollonian', `euler2d', `juggle',
429 `polyominoes' and `thornbird', from xlockmore.
430 * Merged recent xlockmore changes into `ant', `braid',
431 `demon', `discrete', `drift', `fadeplot', `forest',
432 `grav', `hopalong', `ifs', `laser', `lightning',
433 `lisa', `lissie', `loop', `mountain', `penrose',
434 `rotor', `sierpinski', `slip', `sphere', `spiral',
435 `strange', and `vines'.
436 * Fixed the `gltext' bug that sometimes caused
437 horizontal lines to vanish again. This time for sure.
438 * Sped up `webcollage' by adding a C helper program to
439 replace the PPM pipeline. It also pastes images
440 semi-transparently now.
441 * Added support for the gdk_pixbuf library: if this lib
442 is available, then `blitspin', `xflame', and `flag'
443 can load GIF, JPEG, and PNG images in addition to XPM
445 * Fixed a rare race condition where the desktop-grabbing
446 hacks could sometimes leave the screen wedged, if the
447 user moved the mouse exactly when they were grabbing
448 the screen image (it would un-wedge the next time the
449 saver timed out or was activated.)
450 * Fixed incorrect colors in the screen-grabbing GL hacks
451 (`gflux' and `flipscreen3d'.)
452 * Made SIGHUP restart the daemon process (though using
453 `xscreensaver-command -restart' is still the preferred
455 * Tweaks to `xspirograph'.
456 * Minor configure and portability tweaks.
457 Changes since 3.34: * Redesigned `xscreensaver-demo' GUI: it now includes
458 small-preview and per-hack configuration dialogs.
459 * Added three new modes of operation: `One Screen Saver',
460 `Blank Screen', and `Don't Blank' (in addition to the
461 historical `Random Screen Saver').
462 * Configure now defaults to installing the hacks in
463 <prefix>/lib/xscreensaver/ instead of <prefix>/bin/.
464 (Most distros already did it this way.)
465 * New GL hacks, `menger', `engine', `flipscreen3d'.
466 * Made `sierpinski3d' be more colorful.
467 * New versions of `xmatrix' and `nerverot'.
468 * Fixed a bug in `starwars' that made the font be drawn
469 with thin lines in -root mode.
470 * Fixed a bad colormap bug in `crystal' that could make
471 *subsequent* hacks malfunction!
472 * Made `gflux' able to grab screen images (`-mode grab').
473 * Updated `webcollage' for recent search engine changes.
474 * Removed most command-line options to `xscreensaver':
475 just edit the ~/.xscreensaver file instead.
476 * Improved behavior on multi-screen and Xinerama systems:
477 the mouse now stays on the screen where the user left
478 it, and the password and splash dialogs always appear
479 on the screen that has the mouse.
480 * Made the splash dialog use more Gtk-like colors;
481 made it have only two buttons, "Settings" and "Help".
482 * Made `sonar' understand `.ssh/known_hosts2' format
483 files, and be better about stripping out illegal
485 Changes since 3.33: * Turned `memoryLimit' off by default, sigh. Apparently
486 some versions of the GL libraries (appear to) allocate
487 hundreds of megs for every GL program, so `memoryLimit'
488 was causing GL programs to malfunction or crash on
490 * Improved fading on TrueColor XFree86 4.1.x systems.
491 * New GL hack, `circuit'.
492 * Added `fuzz' mode to `decayscreen'.
493 * New version of `whirlygig'.
494 * Added links to `xplanet' and `sphereEversion'.
495 * Fixed rare race condition that could make `sonar' hang.
496 * Fixed potential crash in `speedmine'.
497 * Made `xscreensaver-demo' not crash when imageDirectory
498 was set to a non-existent directory.
499 * Made `xscreensaver-getimage-video' invoke XawTV's
500 `streamer' program better.
501 * Made `phosphor' and `starwars' deal with CR, LF,
502 or CRLF line endings.
503 * Changes for Cygwin compilation environments.
504 * Made `sonar' compile on systems that can't ping.
505 * Configure changes for HPUX 10.20.
506 * Made PAM code work on Red Had 4.2 systems.
507 * Made `xscreensaver-command -deactivate' work when the
508 saver is not active: what that does is reset the idle
509 timer, as if keyboard input had been detected. This
510 was added for the benefit of people writing DVD-playing
511 software: they can now prevent the screensaver from
512 kicking in by sending a -deactivate message once a
513 minute while the movie is playing and not paused.
514 * Various minor portability tweaks.
515 Changes since 3.32: * New hacks, `speedmine' and `whirlygig'.
516 * Sped up `pyro', made the explosions look a bit better.
517 * Added better stars to `glplanet' and `starwars'.
518 * Many internal changes to `webcollage'.
519 * Some new options to `attraction'.
520 * Minor fix to `noseguy' to avoid un-erased pixels.
521 * Rewrote the screen-eraser effects so that they complete
522 in the same amount of time regardless of how slow
523 your X server is (some of them were glacial on servers
525 * Fixed a potential free memory reference that could
526 sometimes cause a crash at startup.
527 * Possibly fixed a problem that could cause the daemon
528 to crash with an X error. I was never able to
529 reproduce this problem, but I think I might have
530 figured out what caused it.
531 * Worked around a problem that caused PAM authentication
532 to fail on some Red Hat 7.x systems.
533 * Added a `memoryLimit' parameter that controls the
534 amount of memory a graphics hack may allocate: if they
535 try to allocate more than this, malloc() will fail
536 (and they will exit or (safely) crash, rather than
537 hogging memory.) Default is 50M.
538 * Made `gnome-help-browser' be the default way to display
539 man pages in `xscreensaver-demo', if running on a
541 Changes since 3.31: * The image-manipulating hacks (`slidescreen', etc.) can
542 now operate on randomly chosen image files from disk,
543 or on frames captured from the system's video input,
544 instead of (or in addition to) manipulating images of
546 * Rewrote `vidwhacker' to use the new image-grabbing
548 * Made fading work on TrueColor XFree86 4.x systems.
549 * Fixed a subtle rendering bug in `atlantis' (the fish
551 * Made `atlantis' have a texture simulating light
552 reflections from the surface of the ocean.
553 * Fixed up label placement in `molecule'.
554 * Better color bars in `xteevee'.
555 * Made `install-strip' not try to strip scripts.
556 Changes since 3.30: * Put in more sensible defaults for DPMS, and updated
557 the documentation to reflect the fact that all your
558 DPMS settings are now belong to xscreensaver.
559 * Fixed the `xscreensaver.spec' file so that `--force'
561 * New versions of `rotzoomer' and `nerverot'.
562 * Fixed an OSF/1 compilation problem in `molecule'.
563 Changes since 3.29: * New hacks, `molecule', `dangerball', and `rotzoomer'.
564 * New version of `gflux'.
565 * Made `gltext' able to display the current time.
566 * Fixed a floating-point-precision problem in `gltext'
567 that sometimes caused horizontal lines to vanish.
568 * Removed the `-window-id' option from the hacks:
569 it never worked right, and was unnecessary.
570 * Made the `starwars' hack use thicker lines, antialias
571 the text, and fade out at the far edge instead of just
573 * Fixed an SHM segment leak in `moire'.
574 Changes since 3.28: * Better rendering of the new logo.
575 * New hack, `gltext'.
576 * Added `-planetary' option to `gears', to draw a
577 different kind of gear system.
578 * Made motion and rotation be smoother in `gears',
579 `glplanet', `moebius', `rubik', and `sierpinski3d'.
580 * Improved coloration in `sierpinski3d'.
581 * Made the GL hacks react to window size changes.
582 * Made most of the GL hacks take a -fps option (like
583 `pulsar' did), so you can use them to benchmark your
585 * Fixed the previous fix to `sonar'.
586 * Minor fix to `nerverot'.
587 Made sonar able to ping hosts on DEC OSF1.
588 * Eliminated a bogus "didn't get enough colors" warning
589 in some of the hacks.
590 Changes since 3.27: * New logo for xscreensaver!
591 * New hacks, `starwars' and `stonerview'.
592 * Made the motion of the bouncing ball in `stairs' be a
594 * Made newly-added screenhacks be added to .xscreensaver
595 automatically: if there are hacks in the app-defaults
596 file that are not also in ~/.xscreensaver, they will
597 be added to the end of the list.
598 * Redid the `Screensaver Options' part of the control
599 panel; xscreensaver now lets you configure your DPMS
601 * Fixed some Makefile problems with non-GL builds.
602 * Fixed detection of MesaGL for version 3.3.
603 * Better workaround to Red Hat 7.0's broken gcc.
604 * Added Sparc Solaris kernel panic to `bsod'.
605 Changes since 3.26: * New hacks: `zoom' and `whirlwindwarp'.
606 * Fixed a free-memory-reference bug in `sonar'.
607 * Better error handling when there are no suitable GL
609 * Added diagnostic dialog when xscreensaver-demo is
610 unable to launch xscreensaver (e.g., when running as
612 * Fixed a bug that caused screenhack argument changes
613 to be ignored when xscreensaver-demo was running as
614 root (if "root" and "nobody" have different home
616 * Made the programs default to ":0" if $DISPLAY is unset.
617 * Made the `-verbose' output include information about
618 which server extensions were supported at compile time.
619 * Worked around Red Hat 7.0's broken gcc 2.96.
620 * Updated default delays on the GL hacks to look better
621 on machines with super-fast 3D hardware.
622 * Install `screensaver-properties-capplet' to work around
623 the usual egregious GNOME lossage.
624 Changes since 3.25: * Added "enabled" checkboxes in the list of hacks in
625 xscreensaver-demo (Gtk version only.)
626 * New hacks `hyperball', `xrayswarm', and `gflux'.
627 * New versions of `nerverot', `galaxy', and `hypercube'.
628 * Small fixes to `phosphor', `shadebobs', `xflame',
630 * Added external helper program `xscreensaver-gl-helper'
631 to figure out which X visual to use for OpenGL
633 * Configure updates for XFree86 4.0, and for BSD.
634 * Made it be more tolerant of bogus /etc/group files.
635 * When installing the PAM config file, first try to just
636 copy an existing "xdm" or "login" config file, so that
637 xscreensaver does authentication in the same way as the
639 Changes since 3.24: * New hack, `nerverot'.
640 * Added BSD kernel panic to `bsod'.
641 * New version of `shadebobs'.
642 * New version of `petri'.
643 * Updated `webcollage' to handle recent Altavista URL
644 format changes; made it search the AP photo gallery.
645 * Revamped command-line options of `sonar' and made it
646 properly handle subnets.
647 * The `bubbles' hack can now trickle up or down the
649 * The `xsublim' hack can now read its text from programs.
650 * Support for GLE version 3 in `extrusion'.
651 * Fixed compilation problems in `maze'.
652 * Fixed a rare crash in `flow'.
653 * Fixes for minor installation problems.
654 Changes since 3.23: * Added `-ignorant' option to `maze' hack.
655 * Updates to `critical', `bsod', `xflame', and `flow'.
656 * Added support for Kerberos 5 (via its Kerberos 4
657 compatibility layer.)
658 * Fixed a bad leak in `xteevee'.
659 * Updated `webcollage' to handle recent Altavista URL
661 * Removed xscreensaver-demo's `Ok' and `Cancel' buttons,
662 since they were confusing people: all changes are now
664 * Made xscreensaver-demo install itself into the Gnome
666 Changes since 3.22: * Fixed some misplaced text fields in the Motif version
667 of xscreensaver-demo; fixed a crash in the Gtk version
668 that would happen if the programs list was empty.
669 * Fixed a recently-introduced bug in `pulsar'.
670 * Made `sierpinski3d' use solid tetrahedrons instead of
672 * Added `-trace' option to `xmatrix'.
673 * Added new hacks `xteevee' and `xspirograph'.
674 Changes since 3.21: * Fixed some bugs in xscreensaver-demo.
675 * Rewrote the Motif version of xscreensaver-demo to
676 match the new Gtk version.
677 * The Athena toolkit is no longer supported.
678 Changes since 3.20: * Tweaked the xscreensaver-demo UI (Gtk only.)
679 * Fixed a few visual selection bugs. I think the proper
680 GL visual should be used with nVidia systems now.
681 * Made the Makefiles obey $install_prefix.
682 * Made the `xscreensaver.spec' file able to generate both
683 GL and non-GL packages simultaneously.
684 Changes since 3.19: * Added new hacks `ripples' and `sierpinski3d'.
685 * Made `xscreensaver-command -exit' be silent when no
686 screen saver was running (instead of complaining.)
687 * Made `webcollage' and `vidwhacker' use `xloadimage'
688 when available (in addition to `xli' and `xv'.)
689 * Improved memory usage in `petri' and gave it a hard
690 cap on how much memory it can allocate.
691 * Added `-watch' option to `xscreensaver-command'.
692 * Made `xscreensaver-demo' come up with the
693 most-recently-run hack selected by default.
694 * Rewrote the Gtk version of `xscreensaver-demo'.
695 It's a lot easier to use now.
696 * Extended the format of the programs list in the
697 .xscreensaver file, for the benefit of the new
698 capabilities of `xscreensaver-demo'.
699 NOTE: you might want to delete your ~/.xscreensaver
700 file and allow it to be re-created! The old one
701 should still work, but xscreensaver-demo won't be as
703 Changes since 3.18: * Fixed gcc dependencies in `bumps' and `ccurve'.
704 * New hack, `extrusion'.
705 * Some of the web sites that `webcollage' was using as
706 its sources changed formats; tweaked it to understand
708 * Added typeahead in the password dialog: if the screen
709 is locked, and you unlock it by typing a character,
710 that key will be automatically inserted in the
711 password dialog (unless it is Return, Enter, Space,
712 or a non-printing key like Shift.)
713 * Made `xmatrix' take a `-small' option, since some
714 folks with tiny screens prefer a smaller font.
715 Changes since 3.17: * New versions of `shadebobs', `lmorph', and `distort'.
716 * Added `ccurve', `blaster', and `bumps' hacks.
717 * Replaced `forest' hack with a rewritten version.
718 * Worked around a Xinerama server bug.
719 * Fixed a bug I introduced in 3.10 that caused some
720 hacks to print out superfluous warnings about not
721 having gotten enough colors.
722 * Made `sproingies' obey the `-delay' option.
723 * Fixed a portability bug in `shadebobs'.
724 * Made `webcollage' and `vidwhacker' use `xli' in
725 preference to `xv', if it is available.
726 * Added a new source of images to `webcollage'.
727 * If running under KDE, xscreensaver will add itself to
728 KDE's list of screensavers (via xscreensaver.kss.)
729 * Improved detection of GL libraries.
730 * Made the password dialog include the date and time.
731 Changes since 3.16: * New version of `webcollage' -- deals better with
732 corrupted images, and can use an http proxy.
733 * New hack, `xsublim' (run it in the background,
734 rather than adding it to the programs list.)
735 * The xscreensaver daemon was leaking a file descriptor
736 each time you edited your .xscreensaver file. Fixed.
737 Changes since 3.15: * New version of `shadebobs'.
738 * Improved image selection in `webcollage', and sped it
740 * Made configure find the right version of perl.
741 * Rewrote the CGI part of `webcollage'.
742 * `make clean' was deleting some things it shouldn't.
743 * Fixed a typo in the default programs list.
744 Changes since 3.14: * Added `webcollage' and `shadebobs' hacks.
745 * Added a `-stdout' arg to `vidwhacker' so that it can
746 be used in a pipeline.
747 * Made `petri' use less memory.
748 Changes since 3.13: * Various improvements to the Gtk port.
749 * Turned off PAM by default on Solaris, since PAM seems
750 generally to be misconfigured out-of-the-box.
751 * Made the `--without-gtk' configure option work.
752 * Made configure check the Gtk version number, since it
754 * Fixed a bug in the code that attempted to prevent
755 changes of screen resolution while the screen is
757 * Fixed a race condition in `xscreensaver-demo' that
758 could cause an X error at startup.
759 * Added `-transparent' option to `deluxe'.
760 * Added `petri' hack.
761 Changes since 3.12: * Ported `xscreensaver-demo' to Gtk.
762 * Made it possible to build Motif, Gtk, and Athena
763 versions of `xscreensaver-demo' in the same directory
764 without reconfiguring.
765 * Made `xscreensaver-demo' chase symlinks before writing
766 the .xscreensaver file, so that if .xscreensaver is
767 itself a symlink, the underlying file will be replaced
769 * Some Makefile and configure tweaks for Solaris and
771 * Made it possible to set the fire color in `xflame'.
772 * Made transparency work in TrueColor (for `goop' and
774 * Fixed a multi-head bug introduced by the virtual
776 Changes since 3.11: * Made it so that you can't scroll the screen while the
777 lock dialog is up (with XFree86 virtual viewports.)
778 * Fixed a bug in `flag' that caused bob's chin to get cut
779 off after a few iterations.
780 Changes since 3.10: * Made `xjack' be black-on-white-ish, so that it looks
781 less like a computer screen and more like the
782 typewritten paper it's supposed to be.
783 * New version of `pulsar'.
784 * Fixed Solaris compilation problem in `phosphor'.
785 * Made xscreensaver notice XFree86's virtual root window
786 hack, so that if the X server's root window is larger
787 than the monitor's displayable resolution, the screen
788 saver will limit itself to the area that actually
789 appears on the screen.
790 * Made the xscreensaver daemon do a better job of
791 picking the visual class that should be used for GL
792 programs. Less user intervention should be needed
793 now: you can use the logical visual name `GL' instead
794 of having to figure out by hand which one to use.
795 * Oops, the visual was defaulting to "best" instead of
796 "default", because the .xscreensaver file was not being
797 loaded quite early enough.
798 * Made configure figure out how to build icmp ping
799 support into the `sonar' hack automatically.
800 * Made warnings about not being able to read shadow
801 passwords not be printed if compiled with PAM support.
802 * Improved PAM startup diagnostics.
803 * Worked around the Solaris PAM bug that was causing
804 crashes there, so now PAM is turned on by default.
805 * Made configure detect the number of arguments that
806 pam_strerror() takes, since on Linux, this apparently
807 changed between 2.0 and 2.2, sigh.
808 * Made the /proc/interrupts kludge look for "PS/2 Mouse"
809 as well as "keyboard".
810 * Made xscreensaver notice when there has been a sudden
811 large jump in wall-clock time, and if so, lock right
812 away, instead of waiting for "lockTimeout" to expire
813 first. (Laptops need this for safer recovery from
815 * Added `-throttle' option to `xscreensaver-command'.
816 Changes since 3.09: * Added `phosphor', `xmatrix', and `pulsar' hacks.
817 * Fixed a bug in the color allocator that sometimes
818 caused `starfish' to fall back to monochrome.
819 * Reduced the amount of code that runs before root
820 privileges are disavowed: "normal" and "shadow"
821 passwords now do some initialization as root, but the
822 PAM and Kerberos authorization schemes will be
823 initialized while running as "nobody". Supposedly
824 this closes a potential security hole when using
826 * Added some more sanity checking to configure.
827 Changes since 3.08: * Added `compass', `squiral', `xflame', `wander',
828 `spotlight', and `critical' hacks.
829 * Added some new modes to `decayscreen'.
830 * Made `deluxe' work in monochrome.
831 * Generalized usage of the Double-Buffer server extension
832 in several hacks (`compass', `deluxe', `interference',
833 `kumppa', and `moire2'.)
834 * Fixed another visual-depth problem in `rd-bomb'.
835 * The screen saver will now defer blanking if neither
836 the keyboard nor the mouse could be grabbed. Instead,
837 it will just try again in a few minutes. This fixes
838 a bad interaction between xscreensaver and programs
839 like VMware that hold the mouse and keyboard grabbed
841 * Added a new erase mode (expanding spiral.)
842 Changes since 3.07: * Fixed some bugs in my port of `t3d'.
843 * Added `penetrate' and `deluxe' hacks.
844 * When linking against Motif 2.x, also link against XPM.
845 * Added support for using /proc/interrupts for idle
846 detection on Linux. Now xscreensaver shouldn't kick
847 in when the user is active on a non-X virtual console.
848 * Upgraded to autoconf 2.13.
849 Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
850 in properly; check for _Xsetlocale in -lXintl.)
851 * Portability fixes for sonar.c.
852 * Fixed a compilation problem when you have GL but don't
854 * Made configure notice when MesaGL requires -lpthread.
855 * Made `flame' ignore SIGFPE (not sure if this is the
856 right fix; it seems only to be needed on FreeBSD.)
857 * Kludged `rd-bomb' work on visuals that are of depth 24
858 but that *do not* support pixmaps of depth 32.
859 * Fixed `halo' to work properly in TrueColor.
860 * Changed `xscreensaver.spec' to install the hacks in
861 /usr/X11R6/lib/xscreensaver/ by default, since that's
862 where recent Red Hat distributions put them.
864 * Updated versions of `crystal', `hopalong', and `flow'
866 * Imported `demon' and `loop' modes from xlockmore.
867 Changes since 3.05: * Oops, the "default-n" visual descriptor was broken;
868 it was always installing a colormap if the
869 `installColormap' preference was set, meaning that
870 `xearth', `xv' and friends were using the wrong
871 colors on 8-bit systems.
872 * Turned off HAVE_PING in `sonar', since it compiles
873 on some Linux systems, but not others of similar
875 Changes since 3.04: * Fixed an off-by-1 in `distort'.
876 * Added `sonar' hack.
877 * New version of `glplanet' (with stars.)
878 * Made all hacks exit when you type `q' or `ESC' at them,
879 and made them obey the WM_DELETE_WINDOW ClientMessage.
880 * Fixed a nonfatal buffer overrun in lament (note:
881 lament still doesn't work with MesaGL 3.0: it dies in
882 lambda_textured_triangle1(), which is Mesa's bug, not
884 Changes since 3.03: * Added an `xscreensaver.spec' file, to make it easier
885 for other folks to generate RPMs.
886 * Made the password code work on HPUX in the situation
887 where: ``enhanced security'' is available; but not
888 used; but the user typed a password more than 8
889 characters long anyway. FTSOHPUX.
890 Changes since 3.02: * Made locking work when passwd aging is enabled.
891 * Added support for PAM (Pluggable Authentication
892 Modules.) It is still turned off by default, though,
893 since it doesn't seem to work on Solaris 2.6, and has
894 been behaving erratically on Red Hat 5.1.
895 * Made each possible authentication method be tried in
896 turn until one succeeds; this means that Kerberos is
897 being used, we will first check Kerberos, and if that
898 fails, will then consult the local password file.
900 * Save and restore the bits under the passwd dialog,
901 to avoid leaving a black rectangle behind when
902 unlocking is cancelled.
903 Changes since 3.01: * Not everyone has sys/select.h, sigh...
904 Changes since 3.00: * Some fixes to `reflect'.
906 * Made it log unsuccessful attempts to unlock the screen
908 * Fixed a bug where `xscreensaver-demo' could be seeing
909 a different programs list than `xscreensaver' did.
910 Changes since 2.34: * The xscreensaver daemon no longer links against Motif
911 or Athena: demo-mode and the preferences panel are no
912 longer built in to the daemon, but are now handled by
913 an external program, `xscreensaver-demo'.
914 (I decided that this, along with the recent addition
915 of the `.xscreensaver' config file, justified bumping
916 the version number to 3.00, since this is a fairly
917 major architectural change.)
918 * Lines in the `*programs' resource may now begin with
919 the character "-", meaning "don't run this hack."
920 In this way, it's possible to disable a hack without
921 throwing away the information about it (making it
922 easier to change your mind later.) Eventually the
923 preferences/demo mode GUI should represent this as a
924 checkbox or something.
925 * Fixed a short race condition where it was possible for
926 xscreensaver to die with a BadWindow error if it was
927 blanking the screen just as another window was being
929 * Made it possible to disable specific modes in `bsod'.
930 Changes since 2.33: * Fixed a bug that was making `pipes' generate way too
931 many valves. Made the viewpoint in `pipes' be selected
932 randomly instead of always being -10 degrees.
933 * Fixed a bug in the XSHM code, in the case where the
934 server supports the XSHM extension but is not the same
935 machine as the client.
936 * Made `rd-bomb' default to taking up the whole screen.
937 * Made it not try to do fading/unfading if no PseudoColor
939 * Initial attempt at supporting VT-locking (doesn't work
941 * Eliminated the `captureStdout' resource; now
942 `captureStderr' controls both streams.
943 * Added `-capture-stderr' and `-no-capture-stderr'
944 command-line arguments.
945 * Added `glplanet' hack.
946 * When a hack is selected with `xscreensaver-command
947 -select', that hack will be used until further notice
948 (until the saver turns off, or another activation
950 Changes since 2.32: * Made `xscreensaver-command' print error messages:
951 the xscreensaver daemon now responds to ClientMessage
952 events by writing a response message on a window
953 property, instead of just writing to its stderr.
954 * Made the ~/.xscreensaver file be automatically reloaded
955 when the file date changes.
956 * The password dialog and splash screen no longer depend
957 on Motif or Athena. This should clear up a number of
958 focus problems, and is the first step on the path
959 toward moving all of the Motif/Athena/whatever code
960 out of the xscreensaver daemon, and into external
962 * Don't complain about LessTif 0.86 any more, since the
963 new password dialog makes that problem go away.
964 * Configure tweaks for Irix 6.5, SunOS 5.something.
965 * New `-reflect' option to `distort'.
966 Changes since 2.31: * Added reading and writing of a ~/.xscreensaver file,
967 so that the Preferences panel can save its settings.
968 * New version of `rubik'.
969 * Added `-select N' argument to `xscreensaver-command'.
970 * Oops, left out some of the `bubbles3d' files...
971 Changes since 2.30: * The cursor was invisible in the password dialog. Fixed.
972 * Made configure warn against MesaGL 2.6.
973 * Fixed X error at startup when using non-default visual.
974 * New version of `crystal', `ant', and `atlantis' from
976 * New hack, `bubble3d'.
977 * Added some new modes to `bsod'.
978 Changes since 2.29: * Changed the order in which -lSM and -lICE are linked
979 to be after Motif instead of before (Lesstif on Irix
981 Changes since 2.28: * Work around a bash bug in configure.
982 * Tweaked HPUX paths again. FTSOHPUX.
983 * Made configure recommend against LessTif 0.86, due
984 to a bug in that version that causes a security hole
985 in the screen locking code. LessTif 0.87 will fix it.
986 * Made all of the `--with' options to `configure' accept
987 a directory option as well (so that --with-motif=/FOO
988 will add -I/FOO/include -L/FOO/lib). I believe this is
989 the Configure Party Line of how do to such things.
990 * Fixed a bug where the mouse was left un-grabbed
991 after the first time the graphics hack was changed
992 (simplified all of the mouse-grabbing logic.)
993 * Maybe possibly perhaps made `vidwhacker' really not
994 leave stray xv windows around. This time for sure.
995 * Added a new erase mode (random dots fizzling out.)
996 * Added `-prefs' argument to `xscreensaver-command',
997 that brings up the Preferences dialog directly (it
998 seems that nobody ever noticed the `Preferences' button
999 on the Demo Mode dialog, maybe this will help.)
1000 * Added a splash screen. Turn it off with *splash:false.
1001 Changes since 2.27: * Better macsbug text in `bsod'.
1002 * New version of `distort' with many new modes.
1003 * Plugged a leak in `coral'.
1004 * Tweaked configure for HPUX.
1005 * Removed some compiler warnings.
1006 * More consistent usage of stderr versus stdout.
1007 * More diagnostics should an X error occur.
1008 * Fixed a possible crash in SGI-specific unfading code.
1009 Changes since 2.26: * Improved version of `distort'.
1010 * Made `lament' compile against OpenGL 1.0 (though it
1011 still requires 1.1 to work properly.)
1012 * Updated my email address and home page.
1013 Changes since 2.24: * Improved motion in `rd-bomb'.
1014 * Added XSHM (shared memory extension) support to the
1015 `distort', `interference', `moire', `rd-bomb', and
1016 `swirl' hacks, which speeds them up a bit.
1017 * Added `lament' hack.
1018 Changes since 2.23: * Tweaked the order of the -L options again.
1019 * Cleaned up configure's `--help' message.
1020 * Added `kumppa' hack.
1021 * Smarter maze-solving algorithm in `maze'.
1022 * Took `xlyap' out of the default list of hacks, since
1023 it's just incredibly buggy (and slow.) Maybe someday
1024 someone will fix it...
1025 * Added `distort' hack, but didn't add it to the default
1026 list (yet) because it's still too slow.
1027 * Made the Athena demo dialog look more like the Motif
1028 version; it has a text-entry field now, too.
1029 * Made the Athena password dialog echo asterisks, like
1030 Motif does, instead of using a flyspeck font.
1031 * Some random configure tweaks.
1032 * Added a `timestamp' resource that makes the `-verbose'
1033 messages include the time at which they were printed.
1034 Changes since 2.22: * The fix for SGI's ``scheme'' nonsense broke things, and
1035 let the user's "*background" resource show through.
1036 Fixed it in a different way.
1037 Changes since 2.21: * Added support for the DPMS server extension (Display
1038 Power Management System.)
1039 * Made configure advertize the `--enable-subdir' option a
1040 little more, since that seemed to cause some people
1041 stress. Also, made that directory be built into the
1042 xscreensaver executable, as a hardcoded prefix to
1043 $PATH. (Might help, shouldn't hurt.)
1044 * Made configure prefer the two-arg gettimeofday to the
1045 one-arg version, since AIX doesn't have any prototypes.
1046 * Made it work with Xaw3d (the 3D Athena library.)
1047 * Made `make install' create directories as necessary.
1048 * New version of lmorph from Sverre.
1049 * Added `crystal' and `discreet' hacks from xlockmore.
1050 * Added a new mode to `bsod'.
1051 Changes since 2.20: * Made `xscreensaver-command -time' use different words.
1052 (It now describes the two states as "screen blanked
1053 since..." and "screen non-blanked since..." instead of
1054 "active since..." and "inactive since..." which a lot
1055 of people interpreted as meaning the opposite of what
1057 * Improved some error messages, in the hopes of making
1058 the distinction between the xscreensaver and
1059 xscreensaver-command programs more obvious.
1060 * Rewrote (and reorganized) parts of the xscreensaver and
1061 xscreensaver-command manual pages.
1062 * Renamed xscreensaver's `-lock' command-line option to
1063 be `-lock-mode', to avoid confusion with the `-lock'
1064 option to xscreensaver-command, which does a totally
1066 * Removed xscreensaver's `-demo' command-line option for
1067 a similar reason; use `xscreensaver-command -demo'
1069 * Disabled SGI's ``scheme'' nonsense in a better way than
1070 fully-qualifying the background colors in every single
1072 * Fixed some other minor cosmetic problems when *sgiMode
1074 * Fixed an X error in `bsod -root' (how ironic...)
1075 Changes since 2.19: * Fixed a bug that caused the mouse to sometimes not be
1076 grabbed properly (meaning the window manager menu could
1077 pop up over the demo-mode display.)
1078 * Fixed a bug that made the stderr output sometimes get
1080 * Fixed a bug that made the demo-mode scrollbar move too
1082 * Protected against a possible buffer overflow.

1089 * Added `interference' hack.
1090 * Added `truchet' hack.
1091 * Added `bsod' hack.
1092 * Added some new modes to `vidwhacker'.
1093 Changes since 2.16: * Added a -window-id argument to most hacks, so that they
1094 can draw on arbitrary externally-provided windows.
1095 * Synched with xlockmore 4.11a01.
1096 * Added `flow' hack.
1097 * Added `atlantis' GL hack.
1098 * Renamed `puzzle' hack to `jigsaw', since xlock already
1099 had a different mode called `puzzle'.
1100 * Made it self-configure properly when Motif 2.1.0 is
1101 being used (requires -lXp now, sigh...)
1102 Changes since 2.15: * Made `flag' able to do XPM images.
1103 * New look for the xscreensaver logo (`xroger').

1116 * Split `escher' into `cage' and `moebius', as per
1118 * Changed subprocess handling to use sigaction() instead
1119 of signal() if it's available (this is necessary for
1120 SCO but should work fine on other systems too.)
1121 * Various other tweaks.
1122 Changes since 2.13: * Better fix for the Motif drag-and-die lossage.
1123 * Put in some kludges to work around a LessTif bug.
1124 * XScreenSaver is known to work with LessTif 0.82 now.
1125 * Made fading work on high-end SGI video hardware.
1126 * Fixed another SGI-specific bug in screen grabbing;
1127 will the madness never cease?
1128 * Fixed another crash in `xlyap'.
1129 Changes since 2.12: * Made `decayscreen' do directions other than down.
1130 * Improved `puzzle'.
1131 * Fixed a crash in `xlyap'.
1132 * Added CDE info to the man page, removed `cde.txt'.
1133 * Configure tweaks for Zippy.
1134 * Turned off the signal handling in `bubbles' because
1135 it was sometimes failing to die.
1136 * Added `hacks/xscreensaver-sgigl.c' to make it possible
1137 to run SGI's ElectroPaint hack (/usr/demos/bin/ep)
1138 with xscreensaver. Finally!
1139 * Fixed a buffer overrun in the locking code that some
1140 wily, malicious cracker must have slipped in.

1142 buttons, since it's broken in some old versions of

1145 * Added `puzzle' hack.
1146 * Added `xlyap' hack.
1147 * Added `default-n' as a visual name, so that one can
1148 have -install on by default, but turn it off for
1149 certain poorly-behaved hacks (like xv.)
1150 * Added support for grabbing frames of external video
1151 (on SGI) to the screen-grabbing hacks (decayscreen,
1152 slidescreen, slip, blitspin, and puzzle.)
1153 * Improved look of tiles in `slidescreen'; fixed its
1154 color allocation problem.
