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62 * Removed `xteevee' (superceded by `xanalogtv').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