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 190 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

100 * Fixed a bad bug that caused `vidwhacker' to never die.
101 * Fixed normals and lighting in `polyhedra'.
102 * Don't reuse the window when changing hacks (to work
103 around bugs in some GL implementations.)
104 * Made `xscreensaver-getimage-file' skip thumbnail-sized
106 * Fixed endian problem in `barcode' on non-x86.
107 * Updates to `webcollage', `apple2', `fuzzyflakes',
108 `atunnel', and `pacman'.
109 * Timing tweaks to `bubble3d', `bouncingcow', `engine',
110 `gltext', `lavalite', `molecule', `spotlight',
111 `sballs', `boxed', `blinkbox', and `circuit'.
112 * Configure updates for Fedora core 2 / xorg 6.7.0.
113 * Compile without warnings under gcc 3.3.3.
114 * I give up: don't blank or lock the screen if we can't
115 get a keyboard grab. In that case, both choices are
117 Changes since 4.15: * New hacks, `polyhedra', `fuzzyflakes', `antinspect',
119 * Minor updates to `webcollage', `bsod', `endgame',
120 `antspotlight', `xmatrix', and `glmatrix'.
121 * Added support for the RANDR (Resize and Rotate)
122 extension to detect when the size of the desktop has
123 been changed while xscreensaver is already running.
124 * Possibly-futile attempt to work around "rdesktop"
126 * Made `xscreensaver-getimage -file' still work even if
127 imageDirectory is unset.
128 * Convert Latin1 to ASCII in `starwars' and `phosphor'
129 (since the GLUT font only has ASCII glyphs.)
130 * Fixed randomization in `noof'.
131 * Added "GetViewPortIsFullOfLies" preference to work
132 around longstanding XFree86 bug #421.
133 * Made `sonar' subnet pinging work properly on bigendian

135 Changes since 4.14: * New hacks, `wormhole', `mismunch', `noof', and
137 * `phosphor' and `apple2' include vt100 emulators now:
138 this means you can do "phosphor -program top", or
139 can use either program as an xterm replacement:
140 "apple2 -text -fast -program 'xemacs -nw'".
141 * `analogtv' (and related) fill the screen better.
142 * The '-gradient' option works in `atlantis' now.
143 * Minor updates to `blinkbox', `queens', `endgame',

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