4 a screen saver and locker for the X window system
7 http://www.jwz.org/xscreensaver/
15 The `configure' shell script will attempt to figure out which options are
16 appropriate for your system, and will create config.h and the various
17 Makefiles for you. Run `configure --help' to see how to override these
18 choices, or to specify things like the default installation directory.
19 The file `INSTALL' gives a general overview of use of these sorts of
20 configure scripts (those generated by the GNU autoconf system.)
22 If you have libraries in non-standard places, you can specify their
23 locations with options like this:
25 ./configure --with-motif=/opt/Motif --with-xpm=/usr/local
27 On MacOS X, it is strongly recommended that you install Fink first
28 (http://fink.sourceforge.net/). With Fink installed, you probably want
29 to pass --prefix=/sw to configure.
31 To build on VMS, see README.VMS.
33 If you think you've found a bug, please let me know! No bug report is too
34 small. But first, please read the enclosed `README.debugging' file to find
35 out what kind of information would be most helpful to include in your bug
40 You can try out xscreensaver like so:
45 The XScreenSaver suite of applications uses a client-server model:
46 The `xscreensaver' program is a daemon that runs in the background;
47 it is controlled by the foreground `xscreensaver-demo' program.
49 xscreensaver has an extensive manual -- please read it!
53 The xscreensaver daemon waits until the keyboard and mouse have been idle
54 for a period, and then runs a graphics demo chosen at random. The demo is
55 terminated as soon as there is any mouse or keyboard activity (or, in
56 locking mode, when the proper password is typed.)
58 It is trivially easy to add new display modes to xscreensaver: any program
59 which can be invoked in such a way that it draws on the root window of the
60 screen can be used as a screensaver. You just change a config file --
61 there's no need to recompile or reinstall anything.
65 Along with the xscreensaver daemon itself, this package also includes
66 numerous graphics hacks for use as screensavers. There is nothing
67 magic about these: they are just programs that draw on the root window.
68 More than 175 such programs are included. For details, see the
69 xscreensaver web page, or the enclosed manual pages.
71 The latest version of xscreensaver is always available on the web at
72 http://www.jwz.org/xscreensaver/.
74 Looking for tips on writing your own screensavers? There is an entry in
75 the XScreenSaver FAQ about that: http://www.jwz.org/xscreensaver/faq.html
79 Changes since 4.14: * New hacks, `wormhole', `mismunch', `noof', and
81 * `phosphor' and `apple2' include vt100 emulators now:
82 this means you can do "phosphor -program top", or
83 can use either program as an xterm replacement:
84 "apple2 -text -fast -program 'xemacs -nw'".
85 * `analogtv' (and related) fill the screen better.
86 * The '-gradient' option works in `atlantis' now.
87 * Minor updates to `blinkbox', `queens', `endgame',
88 `glmatrix', `mirrorblob', `blocktube', and `molecule'.
89 * Integrated SuSE's "external passwd helper" support.
90 * Marginally better /tmp handling in various programs.
91 * Updated config defaults for xplanet 1.0.3.
93 Changes since 4.13: * New hacks, `fontglide', `apple2', `xanalogtv', `pong',
94 `gleidescope', `mirrorblob', and `blinkbox'.
95 * New version of `glsnake' (with many more models.)
96 * Another Windows crash in `bsod'; also HVX/GCOS6/TPS6.
97 * New version of `endgame'.
98 * Screen grabbing works on MacOS X.
99 * Various minor fixes.
100 Changes since 4.12: * On Xinerama systems, xscreensaver now runs one hack on
101 each monitor (just like in "real" multi-head mode)
102 instead of running one hack stretching across all the
103 screens. Note that for this to work with any 3rd party
104 screensavers, they must update their "vroot.h" file.
105 * `webcollage' and `vidwhacker' display images using
106 `xscreensaver-getimage' now.
107 * Added `ljlatest' script for use with `starwars' and
109 Changes since 4.11: * New GL hacks, `flipflop', `antspotlight', and
111 * Added VMS to `bsod'.
112 * Compile without warnings in "gcc -pedantic".
113 * Updates to `webcollage' and `queens'.
114 * Fixed a bug that could cause PAM to hang.
115 Changes since 4.10: * New hacks, `hypertorus', `cubestorm', `glknots',
116 `blocktube', and `glmatrix'.
117 * Updates to `cloudlife', `engine', `xmatrix', and
119 * Rewrote `glslideshow': it should work on somewhat
120 wimpier video cards now.
121 * Various portability tweaks.
122 Changes since 4.09: * New hacks, `cloudlife' and `klein'.
123 * Added Apple ][+, HPUX, and OS/390 sessions to BSOD.
124 * Added some Matrix Reloaded text to `xmatrix'.
125 * Updates to `webcollage', `eruption', `jigglypuff',
126 `metaballs', and `endgame'.
127 * Completely ignore the `memoryLimit' setting now,
128 since it was still causing people GL grief.
129 * Various minor fixes.
130 Changes since 4.08: * New hacks, `flyingtoasters', `bouncingcow',
131 `jigglypuff', and `glslideshow'.
132 * More models in `engine'.
133 * Rewrote `xscreensaver-getimage' to remove reliance on
134 external image loaders (xv, chbg, xloadimage, etc.)
135 and to reduce flicker when loading files.
136 * Made `gflux' and `flipscreen3d' be mouse-spinnable.
137 Changes since 4.07: * New hacks, `atunnels' and `piecewise'.
138 * Physics improvement in `fluidballs'.
139 * Various fixes for XDarwin systems (X11 on MacOS X.)
140 * Added -clock option to `barcode'.
141 * Minor fixes to `endgame', `flurry', `flipscreen3d',
143 Changes since 4.06: * New hacks, `flurry', `metaballs', `eruption',
144 `popsquares', and `barcode'.
145 * Minor updates to `maze' for high density mazes.
146 * Added double buffering to `fluidballs' and `whirlygig'.
147 * Bug fixes for running xscreensaver to a remote XFree86
148 display (which nobody would ever do...)
149 * Updated `webcollage' (faster Alta Vista searching.)
150 * Updated `glplanet' so the sun sets in the west.
151 * Updated `sproingies' with smooth, unsegmented surfaces.
152 * Fixed Perl version-sensitivity in
153 `xscreensaver-getimage-file'.
154 * Fixed GTK2 scrolling bug in `xscreensaver-demo'.
155 Changes since 4.05: * New hack, `glblur' (disabled by default, since it
156 requires fast OpenGL texture support.)
157 * New hack, `halftone'.
158 * Updates to `endgame', `queens', `bumps', `glplanet',
159 `engine', and `circuit'.
160 * New version of `menger' that uses far fewer polygons.
161 * Fixed minor bug in `critical' that could cause some
162 bogus X servers to crash.
163 * Better labels in `molecule': the labels now appear to
164 be attached to the atoms, instead of floating in front
166 * Fixed bug that could rarely cause GL hacks to fail to
167 double-buffer (causing intermittent flickering.)
168 * Fixed a relative-URL-parsing bug in `webcollage'.
169 * Fixed a bug that (sometimes) caused the window manager
170 close box to kill `xscreensaver-demo' with a crash
171 instead of a graceful exit.
172 * Updated xscreensaver.pam to the Red Hat 7.3 way.
173 * More Gnome2-related configure crap.
174 * Updated to latest `config.guess' and `config.sub'.
175 * Fixed occasional core dump in `distort'.
176 * Added a Linux fsck failure and kernel panic to `bsod'.
177 * Added MacOS X kernel panic to `bsod'.
178 * Fixed a bug in `bsod' (all bsod bugs are ironic.)
179 * Fixed a bug that caused `xscreensaver-gl-helper' to
180 print a nonsense visual ID with some versions of
181 `printf': this could cause GL programs to display
182 incorrectly (e.g., flickery.)
183 Changes since 4.04: * More `configure' tweaks to try and get things working
184 on systems that both Gtk 1.x and 2.x installed.
185 * New hack, `endgame'.
186 * Minor updates to `gltext'.
187 Changes since 4.03: * Support for GTK 2.x / GNOME 2.x.
188 * The `configure' script will now use `pkg-config' if
189 you have it, in preference to `gtk-config', etc.
190 * New hacks, `lavalite', `queens', and `anemone'.
191 * Minor updates to `spheremonics', `gltext', `xmatrix'.
192 * You can use the mouse to manually spin most of the GL
193 hacks now (when they are displaying in a window.)
194 * Fixed a bug in `webcollage' (due to recent Alta Vista
195 url changes) that was causing it to try and load
196 incorrect image URLs.
197 * Made `xscreensaver-getimage' use gdk_pixbuf if it is
198 available: this means that those hacks that load images
199 will no longer rely on "xv", "xloadimage", etc. This
200 will close a race condition that could sometimes cause
201 your desktop background to be changed; and also makes
202 it possible for those programs to operate on image
203 files when running in windowed mode.
204 * `webcollage' can now be used in conjunction with
205 `driftnet' to display images snooped from your local
206 ethernet instead of obtained from search engines.
207 * Added man pages for all the hacks that didn't have
209 Changes since 4.02: * New hack, `spheremonics'.
210 * Minor updates to `webcollage', `cage', `moebius',
211 `morph3d', `boxed', `circuit', and `helix'.
212 * `pulsar' and `extrusion' can now load texture JPEGs.
213 * `rubik' now does non-square cubes.
214 * `fluidballs' now does various sizes of balls.
215 * `menger' and `sierpinski3d' now also show polygon
217 * `molecule' displays real subscripts in the formulae.
218 * GTK internationalization/localization support.
219 * Better detection of the various versions of libxml.
220 * Upgraded to autoconf 2.53 (from 2.13.)
221 Changes since 4.01: * Plugged a few minor leaks in `xscreensaver' and
223 * New hacks, `cubenetic' and `fluidballs'.
225 * Fixed sphere projection error in `glplanet'; installed
226 a better image of earth.
227 * Added Win2K and MacOS 1 crashes to `bsod'.
228 * Put back previous (better) version of `forest' that
229 was accidentially downgraded in the last release.
230 * New version of `bumps'.
231 * Made FPS computation in GL hacks more efficient: it
232 will influence the results less, thus resulting in
233 higher (but more accurate) reported frame rates.
234 Changes since 4.00: * New hacks: `twang', `glsnake', `boxed', `sballs',
236 * New hacks `apollonian', `euler2d', `juggle',
237 `polyominoes' and `thornbird', from xlockmore.
238 * Merged recent xlockmore changes into `ant', `braid',
239 `demon', `discrete', `drift', `fadeplot', `forest',
240 `grav', `hopalong', `ifs', `laser', `lightning',
241 `lisa', `lissie', `loop', `mountain', `penrose',
242 `rotor', `sierpinski', `slip', `sphere', `spiral',
243 `strange', and `vines'.
244 * Fixed the `gltext' bug that sometimes caused
245 horizontal lines to vanish again. This time for sure.
246 * Sped up `webcollage' by adding a C helper program to
247 replace the PPM pipeline. It also pastes images
248 semi-transparently now.
249 * Added support for the gdk_pixbuf library: if this lib
250 is available, then `blitspin', `xflame', and `flag'
251 can load GIF, JPEG, and PNG images in addition to XPM
253 * Fixed a rare race condition where the desktop-grabbing
254 hacks could sometimes leave the screen wedged, if the
255 user moved the mouse exactly when they were grabbing
256 the screen image (it would un-wedge the next time the
257 saver timed out or was activated.)
258 * Fixed incorrect colors in the screen-grabbing GL hacks
259 (`gflux' and `flipscreen3d'.)
260 * Made SIGHUP restart the daemon process (though using
261 `xscreensaver-command -restart' is still the preferred
263 * Tweaks to `xspirograph'.
264 * Minor configure and portability tweaks.
265 Changes since 3.34: * Redesigned `xscreensaver-demo' GUI: it now includes
266 small-preview and per-hack configuration dialogs.
267 * Added three new modes of operation: `One Screen Saver',
268 `Blank Screen', and `Don't Blank' (in addition to the
269 historical `Random Screen Saver').
270 * Configure now defaults to installing the hacks in
271 <prefix>/lib/xscreensaver/ instead of <prefix>/bin/.
272 (Most distros already did it this way.)
273 * New GL hacks, `menger', `engine', `flipscreen3d'.
274 * Made `sierpinski3d' be more colorful.
275 * New versions of `xmatrix' and `nerverot'.
276 * Fixed a bug in `starwars' that made the font be drawn
277 with thin lines in -root mode.
278 * Fixed a bad colormap bug in `crystal' that could make
279 *subsequent* hacks malfunction!
280 * Made `gflux' able to grab screen images (`-mode grab').
281 * Updated `webcollage' for recent search engine changes.
282 * Removed most command-line options to `xscreensaver':
283 just edit the ~/.xscreensaver file instead.
284 * Improved behavior on multi-screen and Xinerama systems:
285 the mouse now stays on the screen where the user left
286 it, and the password and splash dialogs always appear
287 on the screen that has the mouse.
288 * Made the splash dialog use more Gtk-like colors;
289 made it have only two buttons, "Settings" and "Help".
290 * Made `sonar' understand `.ssh/known_hosts2' format
291 files, and be better about stripping out illegal
293 Changes since 3.33: * Turned `memoryLimit' off by default, sigh. Apparently
294 some versions of the GL libraries (appear to) allocate
295 hundreds of megs for every GL program, so `memoryLimit'
296 was causing GL programs to malfunction or crash on
298 * Improved fading on TrueColor XFree86 4.1.x systems.
299 * New GL hack, `circuit'.
300 * Added `fuzz' mode to `decayscreen'.
301 * New version of `whirlygig'.
302 * Added links to `xplanet' and `sphereEversion'.
303 * Fixed rare race condition that could make `sonar' hang.
304 * Fixed potential crash in `speedmine'.
305 * Made `xscreensaver-demo' not crash when imageDirectory
306 was set to a non-existent directory.
307 * Made `xscreensaver-getimage-video' invoke XawTV's
308 `streamer' program better.
309 * Made `phosphor' and `starwars' deal with CR, LF,
310 or CRLF line endings.
311 * Changes for Cygwin compilation environments.
312 * Made `sonar' compile on systems that can't ping.
313 * Configure changes for HPUX 10.20.
314 * Made PAM code work on Red Had 4.2 systems.
315 * Made `xscreensaver-command -deactivate' work when the
316 saver is not active: what that does is reset the idle
317 timer, as if keyboard input had been detected. This
318 was added for the benefit of people writing DVD-playing
319 software: they can now prevent the screensaver from
320 kicking in by sending a -deactivate message once a
321 minute while the movie is playing and not paused.
322 * Various minor portability tweaks.
323 Changes since 3.32: * New hacks, `speedmine' and `whirlygig'.
324 * Sped up `pyro', made the explosions look a bit better.
325 * Added better stars to `glplanet' and `starwars'.
326 * Many internal changes to `webcollage'.
327 * Some new options to `attraction'.
328 * Minor fix to `noseguy' to avoid un-erased pixels.
329 * Rewrote the screen-eraser effects so that they complete
330 in the same amount of time regardless of how slow
331 your X server is (some of them were glacial on servers
333 * Fixed a potential free memory reference that could
334 sometimes cause a crash at startup.
335 * Possibly fixed a problem that could cause the daemon
336 to crash with an X error. I was never able to
337 reproduce this problem, but I think I might have
338 figured out what caused it.
339 * Worked around a problem that caused PAM authentication
340 to fail on some Red Hat 7.x systems.
341 * Added a `memoryLimit' parameter that controls the
342 amount of memory a graphics hack may allocate: if they
343 try to allocate more than this, malloc() will fail
344 (and they will exit or (safely) crash, rather than
345 hogging memory.) Default is 50M.
346 * Made `gnome-help-browser' be the default way to display
347 man pages in `xscreensaver-demo', if running on a
349 Changes since 3.31: * The image-manipulating hacks (`slidescreen', etc.) can
350 now operate on randomly chosen image files from disk,
351 or on frames captured from the system's video input,
352 instead of (or in addition to) manipulating images of
354 * Rewrote `vidwhacker' to use the new image-grabbing
356 * Made fading work on TrueColor XFree86 4.x systems.
357 * Fixed a subtle rendering bug in `atlantis' (the fish
359 * Made `atlantis' have a texture simulating light
360 reflections from the surface of the ocean.
361 * Fixed up label placement in `molecule'.
362 * Better color bars in `xteevee'.
363 * Made `install-strip' not try to strip scripts.
364 Changes since 3.30: * Put in more sensible defaults for DPMS, and updated
365 the documentation to reflect the fact that all your
366 DPMS settings are now belong to xscreensaver.
367 * Fixed the `xscreensaver.spec' file so that `--force'
369 * New versions of `rotzoomer' and `nerverot'.
370 * Fixed an OSF/1 compilation problem in `molecule'.
371 Changes since 3.29: * New hacks, `molecule', `dangerball', and `rotzoomer'.
372 * New version of `gflux'.
373 * Made `gltext' able to display the current time.
374 * Fixed a floating-point-precision problem in `gltext'
375 that sometimes caused horizontal lines to vanish.
376 * Removed the `-window-id' option from the hacks:
377 it never worked right, and was unnecessary.
378 * Made the `starwars' hack use thicker lines, antialias
379 the text, and fade out at the far edge instead of just
381 * Fixed an SHM segment leak in `moire'.
382 Changes since 3.28: * Better rendering of the new logo.
383 * New hack, `gltext'.
384 * Added `-planetary' option to `gears', to draw a
385 different kind of gear system.
386 * Made motion and rotation be smoother in `gears',
387 `glplanet', `moebius', `rubik', and `sierpinski3d'.
388 * Improved coloration in `sierpinski3d'.
389 * Made the GL hacks react to window size changes.
390 * Made most of the GL hacks take a -fps option (like
391 `pulsar' did), so you can use them to benchmark your
393 * Fixed the previous fix to `sonar'.
394 * Minor fix to `nerverot'.
395 Made sonar able to ping hosts on DEC OSF1.
396 * Eliminated a bogus "didn't get enough colors" warning
397 in some of the hacks.
398 Changes since 3.27: * New logo for xscreensaver!
399 * New hacks, `starwars' and `stonerview'.
400 * Made the motion of the bouncing ball in `stairs' be a
402 * Made newly-added screenhacks be added to .xscreensaver
403 automatically: if there are hacks in the app-defaults
404 file that are not also in ~/.xscreensaver, they will
405 be added to the end of the list.
406 * Redid the `Screensaver Options' part of the control
407 panel; xscreensaver now lets you configure your DPMS
409 * Fixed some Makefile problems with non-GL builds.
410 * Fixed detection of MesaGL for version 3.3.
411 * Better workaround to Red Hat 7.0's broken gcc.
412 * Added Sparc Solaris kernel panic to `bsod'.
413 Changes since 3.26: * New hacks: `zoom' and `whirlwindwarp'.
414 * Fixed a free-memory-reference bug in `sonar'.
415 * Better error handling when there are no suitable GL
417 * Added diagnostic dialog when xscreensaver-demo is
418 unable to launch xscreensaver (e.g., when running as
420 * Fixed a bug that caused screenhack argument changes
421 to be ignored when xscreensaver-demo was running as
422 root (if "root" and "nobody" have different home
424 * Made the programs default to ":0" if $DISPLAY is unset.
425 * Made the `-verbose' output include information about
426 which server extensions were supported at compile time.
427 * Worked around Red Hat 7.0's broken gcc 2.96.
428 * Updated default delays on the GL hacks to look better
429 on machines with super-fast 3D hardware.
430 * Install `screensaver-properties-capplet' to work around
431 the usual egregious GNOME lossage.
432 Changes since 3.25: * Added "enabled" checkboxes in the list of hacks in
433 xscreensaver-demo (Gtk version only.)
434 * New hacks `hyperball', `xrayswarm', and `gflux'.
435 * New versions of `nerverot', `galaxy', and `hypercube'.
436 * Small fixes to `phosphor', `shadebobs', `xflame',
438 * Added external helper program `xscreensaver-gl-helper'
439 to figure out which X visual to use for OpenGL
441 * Configure updates for XFree86 4.0, and for BSD.
442 * Made it be more tolerant of bogus /etc/group files.
443 * When installing the PAM config file, first try to just
444 copy an existing "xdm" or "login" config file, so that
445 xscreensaver does authentication in the same way as the
447 Changes since 3.24: * New hack, `nerverot'.
448 * Added BSD kernel panic to `bsod'.
449 * New version of `shadebobs'.
450 * New version of `petri'.
451 * Updated `webcollage' to handle recent Altavista URL
452 format changes; made it search the AP photo gallery.
453 * Revamped command-line options of `sonar' and made it
454 properly handle subnets.
455 * The `bubbles' hack can now trickle up or down the
457 * The `xsublim' hack can now read its text from programs.
458 * Support for GLE version 3 in `extrusion'.
459 * Fixed compilation problems in `maze'.
460 * Fixed a rare crash in `flow'.
461 * Fixes for minor installation problems.
462 Changes since 3.23: * Added `-ignorant' option to `maze' hack.
463 * Updates to `critical', `bsod', `xflame', and `flow'.
464 * Added support for Kerberos 5 (via its Kerberos 4
465 compatibility layer.)
466 * Fixed a bad leak in `xteevee'.
467 * Updated `webcollage' to handle recent Altavista URL
469 * Removed xscreensaver-demo's `Ok' and `Cancel' buttons,
470 since they were confusing people: all changes are now
472 * Made xscreensaver-demo install itself into the Gnome
474 Changes since 3.22: * Fixed some misplaced text fields in the Motif version
475 of xscreensaver-demo; fixed a crash in the Gtk version
476 that would happen if the programs list was empty.
477 * Fixed a recently-introduced bug in `pulsar'.
478 * Made `sierpinski3d' use solid tetrahedrons instead of
480 * Added `-trace' option to `xmatrix'.
481 * Added new hacks `xteevee' and `xspirograph'.
482 Changes since 3.21: * Fixed some bugs in xscreensaver-demo.
483 * Rewrote the Motif version of xscreensaver-demo to
484 match the new Gtk version.
485 * The Athena toolkit is no longer supported.
486 Changes since 3.20: * Tweaked the xscreensaver-demo UI (Gtk only.)
487 * Fixed a few visual selection bugs. I think the proper
488 GL visual should be used with nVidia systems now.
489 * Made the Makefiles obey $install_prefix.
490 * Made the `xscreensaver.spec' file able to generate both
491 GL and non-GL packages simultaneously.
492 Changes since 3.19: * Added new hacks `ripples' and `sierpinski3d'.
493 * Made `xscreensaver-command -exit' be silent when no
494 screen saver was running (instead of complaining.)
495 * Made `webcollage' and `vidwhacker' use `xloadimage'
496 when available (in addition to `xli' and `xv'.)
497 * Improved memory usage in `petri' and gave it a hard
498 cap on how much memory it can allocate.
499 * Added `-watch' option to `xscreensaver-command'.
500 * Made `xscreensaver-demo' come up with the
501 most-recently-run hack selected by default.
502 * Rewrote the Gtk version of `xscreensaver-demo'.
503 It's a lot easier to use now.
504 * Extended the format of the programs list in the
505 .xscreensaver file, for the benefit of the new
506 capabilities of `xscreensaver-demo'.
507 NOTE: you might want to delete your ~/.xscreensaver
508 file and allow it to be re-created! The old one
509 should still work, but xscreensaver-demo won't be as
511 Changes since 3.18: * Fixed gcc dependencies in `bumps' and `ccurve'.
512 * New hack, `extrusion'.
513 * Some of the web sites that `webcollage' was using as
514 its sources changed formats; tweaked it to understand
516 * Added typeahead in the password dialog: if the screen
517 is locked, and you unlock it by typing a character,
518 that key will be automatically inserted in the
519 password dialog (unless it is Return, Enter, Space,
520 or a non-printing key like Shift.)
521 * Made `xmatrix' take a `-small' option, since some
522 folks with tiny screens prefer a smaller font.
523 Changes since 3.17: * New versions of `shadebobs', `lmorph', and `distort'.
524 * Added `ccurve', `blaster', and `bumps' hacks.
525 * Replaced `forest' hack with a rewritten version.
526 * Worked around a Xinerama server bug.
527 * Fixed a bug I introduced in 3.10 that caused some
528 hacks to print out superfluous warnings about not
529 having gotten enough colors.
530 * Made `sproingies' obey the `-delay' option.
531 * Fixed a portability bug in `shadebobs'.
532 * Made `webcollage' and `vidwhacker' use `xli' in
533 preference to `xv', if it is available.
534 * Added a new source of images to `webcollage'.
535 * If running under KDE, xscreensaver will add itself to
536 KDE's list of screensavers (via xscreensaver.kss.)
537 * Improved detection of GL libraries.
538 * Made the password dialog include the date and time.
539 Changes since 3.16: * New version of `webcollage' -- deals better with
540 corrupted images, and can use an http proxy.
541 * New hack, `xsublim' (run it in the background,
542 rather than adding it to the programs list.)
543 * The xscreensaver daemon was leaking a file descriptor
544 each time you edited your .xscreensaver file. Fixed.
545 Changes since 3.15: * New version of `shadebobs'.
546 * Improved image selection in `webcollage', and sped it
548 * Made configure find the right version of perl.
549 * Rewrote the CGI part of `webcollage'.
550 * `make clean' was deleting some things it shouldn't.
551 * Fixed a typo in the default programs list.
552 Changes since 3.14: * Added `webcollage' and `shadebobs' hacks.
553 * Added a `-stdout' arg to `vidwhacker' so that it can
554 be used in a pipeline.
555 * Made `petri' use less memory.
556 Changes since 3.13: * Various improvements to the Gtk port.
557 * Turned off PAM by default on Solaris, since PAM seems
558 generally to be misconfigured out-of-the-box.
559 * Made the `--without-gtk' configure option work.
560 * Made configure check the Gtk version number, since it
562 * Fixed a bug in the code that attempted to prevent
563 changes of screen resolution while the screen is
565 * Fixed a race condition in `xscreensaver-demo' that
566 could cause an X error at startup.
567 * Added `-transparent' option to `deluxe'.
568 * Added `petri' hack.
569 Changes since 3.12: * Ported `xscreensaver-demo' to Gtk.
570 * Made it possible to build Motif, Gtk, and Athena
571 versions of `xscreensaver-demo' in the same directory
572 without reconfiguring.
573 * Made `xscreensaver-demo' chase symlinks before writing
574 the .xscreensaver file, so that if .xscreensaver is
575 itself a symlink, the underlying file will be replaced
577 * Some Makefile and configure tweaks for Solaris and
579 * Made it possible to set the fire color in `xflame'.
580 * Made transparency work in TrueColor (for `goop' and
582 * Fixed a multi-head bug introduced by the virtual
584 Changes since 3.11: * Made it so that you can't scroll the screen while the
585 lock dialog is up (with XFree86 virtual viewports.)
586 * Fixed a bug in `flag' that caused bob's chin to get cut
587 off after a few iterations.
588 Changes since 3.10: * Made `xjack' be black-on-white-ish, so that it looks
589 less like a computer screen and more like the
590 typewritten paper it's supposed to be.
591 * New version of `pulsar'.
592 * Fixed Solaris compilation problem in `phosphor'.
593 * Made xscreensaver notice XFree86's virtual root window
594 hack, so that if the X server's root window is larger
595 than the monitor's displayable resolution, the screen
596 saver will limit itself to the area that actually
597 appears on the screen.
598 * Made the xscreensaver daemon do a better job of
599 picking the visual class that should be used for GL
600 programs. Less user intervention should be needed
601 now: you can use the logical visual name `GL' instead
602 of having to figure out by hand which one to use.
603 * Oops, the visual was defaulting to "best" instead of
604 "default", because the .xscreensaver file was not being
605 loaded quite early enough.
606 * Made configure figure out how to build icmp ping
607 support into the `sonar' hack automatically.
608 * Made warnings about not being able to read shadow
609 passwords not be printed if compiled with PAM support.
610 * Improved PAM startup diagnostics.
611 * Worked around the Solaris PAM bug that was causing
612 crashes there, so now PAM is turned on by default.
613 * Made configure detect the number of arguments that
614 pam_strerror() takes, since on Linux, this apparently
615 changed between 2.0 and 2.2, sigh.
616 * Made the /proc/interrupts kludge look for "PS/2 Mouse"
617 as well as "keyboard".
618 * Made xscreensaver notice when there has been a sudden
619 large jump in wall-clock time, and if so, lock right
620 away, instead of waiting for "lockTimeout" to expire
621 first. (Laptops need this for safer recovery from
623 * Added `-throttle' option to `xscreensaver-command'.
624 Changes since 3.09: * Added `phosphor', `xmatrix', and `pulsar' hacks.
625 * Fixed a bug in the color allocator that sometimes
626 caused `starfish' to fall back to monochrome.
627 * Reduced the amount of code that runs before root
628 privileges are disavowed: "normal" and "shadow"
629 passwords now do some initialization as root, but the
630 PAM and Kerberos authorization schemes will be
631 initialized while running as "nobody". Supposedly
632 this closes a potential security hole when using
634 * Added some more sanity checking to configure.
635 Changes since 3.08: * Added `compass', `squiral', `xflame', `wander',
636 `spotlight', and `critical' hacks.
637 * Added some new modes to `decayscreen'.
638 * Made `deluxe' work in monochrome.
639 * Generalized usage of the Double-Buffer server extension
640 in several hacks (`compass', `deluxe', `interference',
641 `kumppa', and `moire2'.)
642 * Fixed another visual-depth problem in `rd-bomb'.
643 * The screen saver will now defer blanking if neither
644 the keyboard nor the mouse could be grabbed. Instead,
645 it will just try again in a few minutes. This fixes
646 a bad interaction between xscreensaver and programs
647 like VMware that hold the mouse and keyboard grabbed
649 * Added a new erase mode (expanding spiral.)
650 Changes since 3.07: * Fixed some bugs in my port of `t3d'.
651 * Added `penetrate' and `deluxe' hacks.
652 * When linking against Motif 2.x, also link against XPM.
653 * Added support for using /proc/interrupts for idle
654 detection on Linux. Now xscreensaver shouldn't kick
655 in when the user is active on a non-X virtual console.
656 * Upgraded to autoconf 2.13.
657 Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
658 in properly; check for _Xsetlocale in -lXintl.)
659 * Portability fixes for sonar.c.
660 * Fixed a compilation problem when you have GL but don't
662 * Made configure notice when MesaGL requires -lpthread.
663 * Made `flame' ignore SIGFPE (not sure if this is the
664 right fix; it seems only to be needed on FreeBSD.)
665 * Kludged `rd-bomb' work on visuals that are of depth 24
666 but that *do not* support pixmaps of depth 32.
667 * Fixed `halo' to work properly in TrueColor.
668 * Changed `xscreensaver.spec' to install the hacks in
669 /usr/X11R6/lib/xscreensaver/ by default, since that's
670 where recent Red Hat distributions put them.
672 * Updated versions of `crystal', `hopalong', and `flow'
674 * Imported `demon' and `loop' modes from xlockmore.
675 Changes since 3.05: * Oops, the "default-n" visual descriptor was broken;
676 it was always installing a colormap if the
677 `installColormap' preference was set, meaning that
678 `xearth', `xv' and friends were using the wrong
679 colors on 8-bit systems.
680 * Turned off HAVE_PING in `sonar', since it compiles
681 on some Linux systems, but not others of similar
683 Changes since 3.04: * Fixed an off-by-1 in `distort'.
684 * Added `sonar' hack.
685 * New version of `glplanet' (with stars.)
686 * Made all hacks exit when you type `q' or `ESC' at them,
687 and made them obey the WM_DELETE_WINDOW ClientMessage.
688 * Fixed a nonfatal buffer overrun in lament (note:
689 lament still doesn't work with MesaGL 3.0: it dies in
690 lambda_textured_triangle1(), which is Mesa's bug, not
692 Changes since 3.03: * Added an `xscreensaver.spec' file, to make it easier
693 for other folks to generate RPMs.
694 * Made the password code work on HPUX in the situation
695 where: ``enhanced security'' is available; but not
696 used; but the user typed a password more than 8
697 characters long anyway. FTSOHPUX.
698 Changes since 3.02: * Made locking work when passwd aging is enabled.
699 * Added support for PAM (Pluggable Authentication
700 Modules.) It is still turned off by default, though,
701 since it doesn't seem to work on Solaris 2.6, and has
702 been behaving erratically on Red Hat 5.1.
703 * Made each possible authentication method be tried in
704 turn until one succeeds; this means that Kerberos is
705 being used, we will first check Kerberos, and if that
706 fails, will then consult the local password file.
708 * Save and restore the bits under the passwd dialog,
709 to avoid leaving a black rectangle behind when
710 unlocking is cancelled.
711 Changes since 3.01: * Not everyone has sys/select.h, sigh...
712 Changes since 3.00: * Some fixes to `reflect'.
714 * Made it log unsuccessful attempts to unlock the screen
716 * Fixed a bug where `xscreensaver-demo' could be seeing
717 a different programs list than `xscreensaver' did.
718 Changes since 2.34: * The xscreensaver daemon no longer links against Motif
719 or Athena: demo-mode and the preferences panel are no
720 longer built in to the daemon, but are now handled by
721 an external program, `xscreensaver-demo'.
722 (I decided that this, along with the recent addition
723 of the `.xscreensaver' config file, justified bumping
724 the version number to 3.00, since this is a fairly
725 major architectural change.)
726 * Lines in the `*programs' resource may now begin with
727 the character "-", meaning "don't run this hack."
728 In this way, it's possible to disable a hack without
729 throwing away the information about it (making it
730 easier to change your mind later.) Eventually the
731 preferences/demo mode GUI should represent this as a
732 checkbox or something.
733 * Fixed a short race condition where it was possible for
734 xscreensaver to die with a BadWindow error if it was
735 blanking the screen just as another window was being
737 * Made it possible to disable specific modes in `bsod'.
738 Changes since 2.33: * Fixed a bug that was making `pipes' generate way too
739 many valves. Made the viewpoint in `pipes' be selected
740 randomly instead of always being -10 degrees.
741 * Fixed a bug in the XSHM code, in the case where the
742 server supports the XSHM extension but is not the same
743 machine as the client.
744 * Made `rd-bomb' default to taking up the whole screen.
745 * Made it not try to do fading/unfading if no PseudoColor
747 * Initial attempt at supporting VT-locking (doesn't work
749 * Eliminated the `captureStdout' resource; now
750 `captureStderr' controls both streams.
751 * Added `-capture-stderr' and `-no-capture-stderr'
752 command-line arguments.
753 * Added `glplanet' hack.
754 * When a hack is selected with `xscreensaver-command
755 -select', that hack will be used until further notice
756 (until the saver turns off, or another activation
758 Changes since 2.32: * Made `xscreensaver-command' print error messages:
759 the xscreensaver daemon now responds to ClientMessage
760 events by writing a response message on a window
761 property, instead of just writing to its stderr.
762 * Made the ~/.xscreensaver file be automatically reloaded
763 when the file date changes.
764 * The password dialog and splash screen no longer depend
765 on Motif or Athena. This should clear up a number of
766 focus problems, and is the first step on the path
767 toward moving all of the Motif/Athena/whatever code
768 out of the xscreensaver daemon, and into external
770 * Don't complain about LessTif 0.86 any more, since the
771 new password dialog makes that problem go away.
772 * Configure tweaks for Irix 6.5, SunOS 5.something.
773 * New `-reflect' option to `distort'.
774 Changes since 2.31: * Added reading and writing of a ~/.xscreensaver file,
775 so that the Preferences panel can save its settings.
776 * New version of `rubik'.
777 * Added `-select N' argument to `xscreensaver-command'.
778 * Oops, left out some of the `bubbles3d' files...
779 Changes since 2.30: * The cursor was invisible in the password dialog. Fixed.
780 * Made configure warn against MesaGL 2.6.
781 * Fixed X error at startup when using non-default visual.
782 * New version of `crystal', `ant', and `atlantis' from
784 * New hack, `bubble3d'.
785 * Added some new modes to `bsod'.
786 Changes since 2.29: * Changed the order in which -lSM and -lICE are linked
787 to be after Motif instead of before (Lesstif on Irix
789 Changes since 2.28: * Work around a bash bug in configure.
790 * Tweaked HPUX paths again. FTSOHPUX.
791 * Made configure recommend against LessTif 0.86, due
792 to a bug in that version that causes a security hole
793 in the screen locking code. LessTif 0.87 will fix it.
794 * Made all of the `--with' options to `configure' accept
795 a directory option as well (so that --with-motif=/FOO
796 will add -I/FOO/include -L/FOO/lib). I believe this is
797 the Configure Party Line of how do to such things.
798 * Fixed a bug where the mouse was left un-grabbed
799 after the first time the graphics hack was changed
800 (simplified all of the mouse-grabbing logic.)
801 * Maybe possibly perhaps made `vidwhacker' really not
802 leave stray xv windows around. This time for sure.
803 * Added a new erase mode (random dots fizzling out.)
804 * Added `-prefs' argument to `xscreensaver-command',
805 that brings up the Preferences dialog directly (it
806 seems that nobody ever noticed the `Preferences' button
807 on the Demo Mode dialog, maybe this will help.)
808 * Added a splash screen. Turn it off with *splash:false.
809 Changes since 2.27: * Better macsbug text in `bsod'.
810 * New version of `distort' with many new modes.
811 * Plugged a leak in `coral'.
812 * Tweaked configure for HPUX.
813 * Removed some compiler warnings.
814 * More consistent usage of stderr versus stdout.
815 * More diagnostics should an X error occur.
816 * Fixed a possible crash in SGI-specific unfading code.
817 Changes since 2.26: * Improved version of `distort'.
818 * Made `lament' compile against OpenGL 1.0 (though it
819 still requires 1.1 to work properly.)
820 * Updated my email address and home page.
821 Changes since 2.24: * Improved motion in `rd-bomb'.
822 * Added XSHM (shared memory extension) support to the
823 `distort', `interference', `moire', `rd-bomb', and
824 `swirl' hacks, which speeds them up a bit.
825 * Added `lament' hack.
826 Changes since 2.23: * Tweaked the order of the -L options again.
827 * Cleaned up configure's `--help' message.
828 * Added `kumppa' hack.
829 * Smarter maze-solving algorithm in `maze'.
830 * Took `xlyap' out of the default list of hacks, since
831 it's just incredibly buggy (and slow.) Maybe someday
832 someone will fix it...
833 * Added `distort' hack, but didn't add it to the default
834 list (yet) because it's still too slow.
835 * Made the Athena demo dialog look more like the Motif
836 version; it has a text-entry field now, too.
837 * Made the Athena password dialog echo asterisks, like
838 Motif does, instead of using a flyspeck font.
839 * Some random configure tweaks.
840 * Added a `timestamp' resource that makes the `-verbose'
841 messages include the time at which they were printed.
842 Changes since 2.22: * The fix for SGI's ``scheme'' nonsense broke things, and
843 let the user's "*background" resource show through.
844 Fixed it in a different way.
845 Changes since 2.21: * Added support for the DPMS server extension (Display
846 Power Management System.)
847 * Made configure advertize the `--enable-subdir' option a
848 little more, since that seemed to cause some people
849 stress. Also, made that directory be built into the
850 xscreensaver executable, as a hardcoded prefix to
851 $PATH. (Might help, shouldn't hurt.)
852 * Made configure prefer the two-arg gettimeofday to the
853 one-arg version, since AIX doesn't have any prototypes.
854 * Made it work with Xaw3d (the 3D Athena library.)
855 * Made `make install' create directories as necessary.
856 * New version of lmorph from Sverre.
857 * Added `crystal' and `discreet' hacks from xlockmore.
858 * Added a new mode to `bsod'.
859 Changes since 2.20: * Made `xscreensaver-command -time' use different words.
860 (It now describes the two states as "screen blanked
861 since..." and "screen non-blanked since..." instead of
862 "active since..." and "inactive since..." which a lot
863 of people interpreted as meaning the opposite of what
865 * Improved some error messages, in the hopes of making
866 the distinction between the xscreensaver and
867 xscreensaver-command programs more obvious.
868 * Rewrote (and reorganized) parts of the xscreensaver and
869 xscreensaver-command manual pages.
870 * Renamed xscreensaver's `-lock' command-line option to
871 be `-lock-mode', to avoid confusion with the `-lock'
872 option to xscreensaver-command, which does a totally
874 * Removed xscreensaver's `-demo' command-line option for
875 a similar reason; use `xscreensaver-command -demo'
877 * Disabled SGI's ``scheme'' nonsense in a better way than
878 fully-qualifying the background colors in every single
880 * Fixed some other minor cosmetic problems when *sgiMode
882 * Fixed an X error in `bsod -root' (how ironic...)
883 Changes since 2.19: * Fixed a bug that caused the mouse to sometimes not be
884 grabbed properly (meaning the window manager menu could
885 pop up over the demo-mode display.)
886 * Fixed a bug that made the stderr output sometimes get
888 * Fixed a bug that made the demo-mode scrollbar move too
890 * Protected against a possible buffer overflow.
891 * Made `vidwhacker' not leave stray xv windows around.
892 * New version of `ant' so that Bagley doesn't calve.
893 * Make configure on AIX get XShm from the right library.
894 Changes since 2.18: * One file was missing from the tar file. Fixed.
895 Changes since 2.17: * Oops, atlantis wasn't being built by default. Fixed.
896 * Added `epicycle' hack.
897 * Added `interference' hack.
898 * Added `truchet' hack.
900 * Added some new modes to `vidwhacker'.
901 Changes since 2.16: * Added a -window-id argument to most hacks, so that they
902 can draw on arbitrary externally-provided windows.
903 * Synched with xlockmore 4.11a01.
905 * Added `atlantis' GL hack.
906 * Renamed `puzzle' hack to `jigsaw', since xlock already
907 had a different mode called `puzzle'.
908 * Made it self-configure properly when Motif 2.1.0 is
909 being used (requires -lXp now, sigh...)
910 Changes since 2.15: * Made `flag' able to do XPM images.
911 * New look for the xscreensaver logo (`xroger').
912 * Fixed compilation error on Suns with adjunct passwords.
913 * Got multi-architecture builds working again.
914 * Some configure tweaks for building on HPUX and Solaris.
915 * Fixed bug in decayscreen.
916 * Fixed typo in passwd.c.
917 * Made `cynosure' not die when colormap is full.
918 Changes since 2.14: * Added `cynosure' hack.
919 * Added `moire2' hack.
920 * Tweaked `erase.c' some more.
921 * Made unfading a bit smoother.
922 * Added `vidwhacker' hack (not installed by default.)
923 * Added `stairs' hack.
924 * Split `escher' into `cage' and `moebius', as per
926 * Changed subprocess handling to use sigaction() instead
927 of signal() if it's available (this is necessary for
928 SCO but should work fine on other systems too.)
929 * Various other tweaks.
930 Changes since 2.13: * Better fix for the Motif drag-and-die lossage.
931 * Put in some kludges to work around a LessTif bug.
932 * XScreenSaver is known to work with LessTif 0.82 now.
933 * Made fading work on high-end SGI video hardware.
934 * Fixed another SGI-specific bug in screen grabbing;
935 will the madness never cease?
936 * Fixed another crash in `xlyap'.
937 Changes since 2.12: * Made `decayscreen' do directions other than down.
939 * Fixed a crash in `xlyap'.
940 * Added CDE info to the man page, removed `cde.txt'.
941 * Configure tweaks for Zippy.
942 * Turned off the signal handling in `bubbles' because
943 it was sometimes failing to die.
944 * Added `hacks/xscreensaver-sgigl.c' to make it possible
945 to run SGI's ElectroPaint hack (/usr/demos/bin/ep)
946 with xscreensaver. Finally!
947 * Fixed a buffer overrun in the locking code that some
948 wily, malicious cracker must have slipped in.
949 * Disabled Motif drag-and-drool in the dialog box
950 buttons, since it's broken in some old versions of
952 Changes since 2.11: * Added `README.debugging'.
953 * Added `puzzle' hack.
954 * Added `xlyap' hack.
955 * Added `default-n' as a visual name, so that one can
956 have -install on by default, but turn it off for
957 certain poorly-behaved hacks (like xv.)
958 * Added support for grabbing frames of external video
959 (on SGI) to the screen-grabbing hacks (decayscreen,
960 slidescreen, slip, blitspin, and puzzle.)
961 * Improved look of tiles in `slidescreen'; fixed its
962 color allocation problem.
963 Changes since 2.10: * Tweaked `blitspin', added it to the default list.
964 * Added `lissie', `mountain', `triangle', `worm',
965 `rotor', and `ant' from xlockmore.
966 * Updated `sierpinski', `galaxy', and `lisa'.
967 * Thickened the lines in `braid' and `lmorph'.
968 * Updated VMS makefiles.
969 * Renamed `fract' to `vines'.
970 * Added `xjack' hack.
971 * Made a few more hacks use erase.c, and added a few
973 * Fixed compilation problem with Sun's version of OpenGL.
974 * Added ability to use sigaction() instead of signal()
975 to work around a SCO kernel bug.
976 Changes since 2.09: * Fixed colormap bugs in `rd-bomb'; sped up `coral'.
977 * Configure tweaks for *BSD.
978 Changes since 2.07: * New hacks `rd-bomb' and `coral'.
979 * New version of `maze' with some new algorithms.
980 * New colorized version of `rocks'.
981 * Fixed a bug in qix on 64-bit machines.
982 * Fixed a bug in the -time option.
983 * Fixed a bug in configure related to LessTif.
984 Changes since 2.06: * Minor header tweaks in windows.c and flag.c.
985 * Made multi-architecture ($VPATH) builds work properly.
986 * Merged new GL stuff from xlockmore (rubik, morph3d.)
987 * Fixed intermittent crashes in `imsmap' and `munch'.
