4 a screen saver and locker for the X window system

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
79 Changes since 4.21: * Fixed a bug in the new mouse-motion code that caused
80 the screen to never blank on multi-head non-Xinerama
82 * New hacks, `interaggregate', `antmaze', `tangram',
84 * Minor tweaks to `fiberlamp', `ifs', `slidescreen',
85 `zoom', `sonar', `fireworkx', `whirlwindwarp',
86 `bubble3d', and `rd-bomb'.
87 * Added motion blur to `blinkbox'.
88 * `bsod' now includes Longhorn's "RSOD", and OS/2.
89 * Fixed `-wireframe' usage in most hacks and man pages.
90 Changes since 4.20: * New hack: `fliptext'.
91 * Changed default configure installation directories:
92 /usr/bin/ for xscreensaver, etc.;
93 /usr/libexec/xscreensaver/ for hacks;
94 /usr/share/xscreensaver/config/ for xml files.
95 * All the text-manipulating screen savers can have their
96 text source configured via `xscreensaver-demo' now.
97 * xscreensaver.spec now builds three RPMs:
98 base (no hacks); extras (2d hacks); and gl-extras.
99 * Added `-program' and `-front' option to `gltext'.
100 * Added `-shells' to `molecule'.
101 * Fixed text-alpha glitch in `carousel'.
102 * New `pacman': the ghosts can be killed now.
103 * Fixed a bug in screen-grabbing GL hacks where images
104 would be tiled instead of scaled on machines that
105 can't do large textures.
106 * `webcollage' can hit Flickr now.
107 * New (rewritten) implementation of `ifs'.
108 * The unlock dialog can be made to have a "New Login"
109 button that will run `gdmflexiserver'. Experimental!
110 * Fixed non-ASCII display bug in `starwars'.
111 * Configure finds a default for imageDirectory.
112 * "xscreensaver-command -lock" now works even if
113 in "screensaver disabled" mode.
114 * If a bad password is typed while CapsLock is on, the
115 unlock dialog says "CapsLock?" instead of "Sorry".
116 * Mouse motion only counts as activity if the mouse moved
117 more than 10 pixels (so the screen won't unblank every
118 time you bump your desk.)
119 * New mode option "random-same": if you have multiple
120 monitors, this will run the *same* randomly chosen
121 hack on each screen, instead of different ones on each.
122 Changes since 4.19: * New hacks, `fiberlamp', `boing', `boxfit', and
124 * Rewrote `glslideshow' again: should be faster now.
125 * Sped up loading of images in GL programs.
126 * `starwars' uses texture-mapped fonts now.
127 * New `bsod' modes: tru64, hppa, and nvidia.
128 * Updates to `webcollage', `juggle', `pinion',
129 `fireworkx', `sonar', `extrusion', `substrate', and
131 Changes since 4.18: * New hacks, `substrate', `intermomentary', `fireworkx',
133 * New version of `flow'.

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