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 180 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

86 * Minor updates to `sonar', `molecule', `glmatrix',
87 `galaxy', and `webcollage'.
88 * Removed support for GTK 1.x (everyone uses 2.x now.)
89 Changes since 4.17: * Oops, pay no attention to the man behind the curtain.
90 Changes since 4.16: * New hacks, `anemotaxis' and `memscroller'.
91 * Fixed a bad bug that caused `vidwhacker' to never die.
92 * Fixed normals and lighting in `polyhedra'.
93 * Don't reuse the window when changing hacks (to work
94 around bugs in some GL implementations.)
95 * Made `xscreensaver-getimage-file' skip thumbnail-sized
97 * Fixed endian problem in `barcode' on non-x86.
98 * Updates to `webcollage', `apple2', `fuzzyflakes',
99 `atunnel', and `pacman'.
100 * Timing tweaks to `bubble3d', `bouncingcow', `engine',
101 `gltext', `lavalite', `molecule', `spotlight',
102 `sballs', `boxed', `blinkbox', and `circuit'.
103 * Configure updates for Fedora core 2 / xorg 6.7.0.
104 * Compile without warnings under gcc 3.3.3.
105 * I give up: don't blank or lock the screen if we can't
106 get a keyboard grab. In that case, both choices are
108 Changes since 4.15: * New hacks, `polyhedra', `fuzzyflakes', `antinspect',
110 * Minor updates to `webcollage', `bsod', `endgame',
111 `antspotlight', `xmatrix', and `glmatrix'.
112 * Added support for the RANDR (Resize and Rotate)
113 extension to detect when the size of the desktop has
114 been changed while xscreensaver is already running.
115 * Possibly-futile attempt to work around "rdesktop"
117 * Made `xscreensaver-getimage -file' still work even if
118 imageDirectory is unset.
119 * Convert Latin1 to ASCII in `starwars' and `phosphor'
120 (since the GLUT font only has ASCII glyphs.)

122 * Added "GetViewPortIsFullOfLies" preference to work
123 around longstanding XFree86 bug #421.
124 * Made `sonar' subnet pinging work properly on bigendian
125 machines (e.g., PPC.)
126 Changes since 4.14: * New hacks, `wormhole', `mismunch', `noof', and
128 * `phosphor' and `apple2' include vt100 emulators now:
129 this means you can do "phosphor -program top", or
130 can use either program as an xterm replacement:
131 "apple2 -text -fast -program 'xemacs -nw'".
132 * `analogtv' (and related) fill the screen better.
133 * The '-gradient' option works in `atlantis' now.
134 * Minor updates to `blinkbox', `queens', `endgame',
135 `glmatrix', `mirrorblob', `blocktube', and `molecule'.

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