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
79 Changes since 4.17: * Oops, pay no attention to the man behind the curtain.
80 Changes since 4.16: * New hacks, `anemotaxis' and `memscroller'.
81 * Fixed a bad bug that caused `vidwhacker' to never die.
82 * Fixed normals and lighting in `polyhedra'.
83 * Don't reuse the window when changing hacks (to work
84 around bugs in some GL implementations.)
85 * Made `xscreensaver-getimage-file' skip thumbnail-sized
87 * Fixed endian problem in `barcode' on non-x86.
88 * Updates to `webcollage', `apple2', `fuzzyflakes',
89 `atunnel', and `pacman'.
90 * Timing tweaks to `bubble3d', `bouncingcow', `engine',
91 `gltext', `lavalite', `molecule', `spotlight',
92 `sballs', `boxed', `blinkbox', and `circuit'.
93 * Configure updates for Fedora core 2 / xorg 6.7.0.
94 * Compile without warnings under gcc 3.3.3.
95 * I give up: don't blank or lock the screen if we can't
96 get a keyboard grab. In that case, both choices are
98 Changes since 4.15: * New hacks, `polyhedra', `fuzzyflakes', `antinspect',
100 * Minor updates to `webcollage', `bsod', `endgame',
101 `antspotlight', `xmatrix', and `glmatrix'.
102 * Added support for the RANDR (Resize and Rotate)
103 extension to detect when the size of the desktop has
104 been changed while xscreensaver is already running.
105 * Possibly-futile attempt to work around "rdesktop"
107 * Made `xscreensaver-getimage -file' still work even if
108 imageDirectory is unset.
109 * Convert Latin1 to ASCII in `starwars' and `phosphor'
110 (since the GLUT font only has ASCII glyphs.)
111 * Fixed randomization in `noof'.
112 * Added "GetViewPortIsFullOfLies" preference to work
113 around longstanding XFree86 bug #421.
114 * Made `sonar' subnet pinging work properly on bigendian
115 machines (e.g., PPC.)
116 Changes since 4.14: * New hacks, `wormhole', `mismunch', `noof', and
118 * `phosphor' and `apple2' include vt100 emulators now:
119 this means you can do "phosphor -program top", or
120 can use either program as an xterm replacement:
121 "apple2 -text -fast -program 'xemacs -nw'".
122 * `analogtv' (and related) fill the screen better.
123 * The '-gradient' option works in `atlantis' now.
124 * Minor updates to `blinkbox', `queens', `endgame',
125 `glmatrix', `mirrorblob', `blocktube', and `molecule'.
126 * Integrated SuSE's "external passwd helper" support.
127 * Marginally better /tmp handling in various programs.
128 * Updated config defaults for xplanet 1.0.3.
130 Changes since 4.13: * New hacks, `fontglide', `apple2', `xanalogtv', `pong',
131 `gleidescope', `mirrorblob', and `blinkbox'.
132 * New version of `glsnake' (with many more models.)
133 * Another Windows crash in `bsod'; also HVX/GCOS6/TPS6.
134 * New version of `endgame'.
135 * Screen grabbing works on MacOS X.
136 * Various minor fixes.
137 Changes since 4.12: * On Xinerama systems, xscreensaver now runs one hack on
138 each monitor (just like in "real" multi-head mode)
139 instead of running one hack stretching across all the
140 screens. Note that for this to work with any 3rd party
141 screensavers, they must update their "vroot.h" file.
142 * `webcollage' and `vidwhacker' display images using
143 `xscreensaver-getimage' now.
144 * Added `ljlatest' script for use with `starwars' and
146 Changes since 4.11: * New GL hacks, `flipflop', `antspotlight', and
148 * Added VMS to `bsod'.
149 * Compile without warnings in "gcc -pedantic".
150 * Updates to `webcollage' and `queens'.
151 * Fixed a bug that could cause PAM to hang.
152 Changes since 4.10: * New hacks, `hypertorus', `cubestorm', `glknots',
153 `blocktube', and `glmatrix'.
154 * Updates to `cloudlife', `engine', `xmatrix', and
156 * Rewrote `glslideshow': it should work on somewhat
157 wimpier video cards now.
158 * Various portability tweaks.
159 Changes since 4.09: * New hacks, `cloudlife' and `klein'.
160 * Added Apple ][+, HPUX, and OS/390 sessions to BSOD.
161 * Added some Matrix Reloaded text to `xmatrix'.
162 * Updates to `webcollage', `eruption', `jigglypuff',
163 `metaballs', and `endgame'.
164 * Completely ignore the `memoryLimit' setting now,
165 since it was still causing people GL grief.
166 * Various minor fixes.
167 Changes since 4.08: * New hacks, `flyingtoasters', `bouncingcow',
168 `jigglypuff', and `glslideshow'.
169 * More models in `engine'.
170 * Rewrote `xscreensaver-getimage' to remove reliance on
171 external image loaders (xv, chbg, xloadimage, etc.)
172 and to reduce flicker when loading files.
173 * Made `gflux' and `flipscreen3d' be mouse-spinnable.
174 Changes since 4.07: * New hacks, `atunnels' and `piecewise'.
175 * Physics improvement in `fluidballs'.
176 * Various fixes for XDarwin systems (X11 on MacOS X.)
177 * Added -clock option to `barcode'.
178 * Minor fixes to `endgame', `flurry', `flipscreen3d',
180 Changes since 4.06: * New hacks, `flurry', `metaballs', `eruption',
181 `popsquares', and `barcode'.
182 * Minor updates to `maze' for high density mazes.
183 * Added double buffering to `fluidballs' and `whirlygig'.
184 * Bug fixes for running xscreensaver to a remote XFree86
185 display (which nobody would ever do...)
186 * Updated `webcollage' (faster Alta Vista searching.)
187 * Updated `glplanet' so the sun sets in the west.
188 * Updated `sproingies' with smooth, unsegmented surfaces.
189 * Fixed Perl version-sensitivity in
190 `xscreensaver-getimage-file'.
191 * Fixed GTK2 scrolling bug in `xscreensaver-demo'.
192 Changes since 4.05: * New hack, `glblur' (disabled by default, since it
193 requires fast OpenGL texture support.)
194 * New hack, `halftone'.
195 * Updates to `endgame', `queens', `bumps', `glplanet',
196 `engine', and `circuit'.
197 * New version of `menger' that uses far fewer polygons.
198 * Fixed minor bug in `critical' that could cause some
199 bogus X servers to crash.
200 * Better labels in `molecule': the labels now appear to
201 be attached to the atoms, instead of floating in front
203 * Fixed bug that could rarely cause GL hacks to fail to
204 double-buffer (causing intermittent flickering.)
205 * Fixed a relative-URL-parsing bug in `webcollage'.
206 * Fixed a bug that (sometimes) caused the window manager
207 close box to kill `xscreensaver-demo' with a crash
208 instead of a graceful exit.
209 * Updated xscreensaver.pam to the Red Hat 7.3 way.
210 * More Gnome2-related configure crap.
211 * Updated to latest `config.guess' and `config.sub'.
212 * Fixed occasional core dump in `distort'.
213 * Added a Linux fsck failure and kernel panic to `bsod'.
214 * Added MacOS X kernel panic to `bsod'.
215 * Fixed a bug in `bsod' (all bsod bugs are ironic.)
216 * Fixed a bug that caused `xscreensaver-gl-helper' to
217 print a nonsense visual ID with some versions of
218 `printf': this could cause GL programs to display
219 incorrectly (e.g., flickery.)
220 Changes since 4.04: * More `configure' tweaks to try and get things working
221 on systems that both Gtk 1.x and 2.x installed.
222 * New hack, `endgame'.
223 * Minor updates to `gltext'.
224 Changes since 4.03: * Support for GTK 2.x / GNOME 2.x.
225 * The `configure' script will now use `pkg-config' if
226 you have it, in preference to `gtk-config', etc.
227 * New hacks, `lavalite', `queens', and `anemone'.
228 * Minor updates to `spheremonics', `gltext', `xmatrix'.
229 * You can use the mouse to manually spin most of the GL
230 hacks now (when they are displaying in a window.)
231 * Fixed a bug in `webcollage' (due to recent Alta Vista
232 url changes) that was causing it to try and load
233 incorrect image URLs.
234 * Made `xscreensaver-getimage' use gdk_pixbuf if it is
235 available: this means that those hacks that load images
236 will no longer rely on "xv", "xloadimage", etc. This
237 will close a race condition that could sometimes cause
238 your desktop background to be changed; and also makes
239 it possible for those programs to operate on image
240 files when running in windowed mode.
241 * `webcollage' can now be used in conjunction with
242 `driftnet' to display images snooped from your local
243 ethernet instead of obtained from search engines.
244 * Added man pages for all the hacks that didn't have
246 Changes since 4.02: * New hack, `spheremonics'.
247 * Minor updates to `webcollage', `cage', `moebius',
248 `morph3d', `boxed', `circuit', and `helix'.
249 * `pulsar' and `extrusion' can now load texture JPEGs.
250 * `rubik' now does non-square cubes.
251 * `fluidballs' now does various sizes of balls.
252 * `menger' and `sierpinski3d' now also show polygon
254 * `molecule' displays real subscripts in the formulae.
255 * GTK internationalization/localization support.
256 * Better detection of the various versions of libxml.
257 * Upgraded to autoconf 2.53 (from 2.13.)
258 Changes since 4.01: * Plugged a few minor leaks in `xscreensaver' and
260 * New hacks, `cubenetic' and `fluidballs'.
262 * Fixed sphere projection error in `glplanet'; installed
263 a better image of earth.
264 * Added Win2K and MacOS 1 crashes to `bsod'.
265 * Put back previous (better) version of `forest' that
266 was accidentially downgraded in the last release.
267 * New version of `bumps'.
268 * Made FPS computation in GL hacks more efficient: it
269 will influence the results less, thus resulting in
270 higher (but more accurate) reported frame rates.
271 Changes since 4.00: * New hacks: `twang', `glsnake', `boxed', `sballs',
273 * New hacks `apollonian', `euler2d', `juggle',
274 `polyominoes' and `thornbird', from xlockmore.
275 * Merged recent xlockmore changes into `ant', `braid',
276 `demon', `discrete', `drift', `fadeplot', `forest',
277 `grav', `hopalong', `ifs', `laser', `lightning',
278 `lisa', `lissie', `loop', `mountain', `penrose',
279 `rotor', `sierpinski', `slip', `sphere', `spiral',
280 `strange', and `vines'.
281 * Fixed the `gltext' bug that sometimes caused
282 horizontal lines to vanish again. This time for sure.
283 * Sped up `webcollage' by adding a C helper program to
284 replace the PPM pipeline. It also pastes images
285 semi-transparently now.
286 * Added support for the gdk_pixbuf library: if this lib
287 is available, then `blitspin', `xflame', and `flag'
288 can load GIF, JPEG, and PNG images in addition to XPM
290 * Fixed a rare race condition where the desktop-grabbing
291 hacks could sometimes leave the screen wedged, if the
292 user moved the mouse exactly when they were grabbing
293 the screen image (it would un-wedge the next time the
294 saver timed out or was activated.)
295 * Fixed incorrect colors in the screen-grabbing GL hacks
296 (`gflux' and `flipscreen3d'.)
297 * Made SIGHUP restart the daemon process (though using
298 `xscreensaver-command -restart' is still the preferred
300 * Tweaks to `xspirograph'.
301 * Minor configure and portability tweaks.
302 Changes since 3.34: * Redesigned `xscreensaver-demo' GUI: it now includes
303 small-preview and per-hack configuration dialogs.
304 * Added three new modes of operation: `One Screen Saver',
305 `Blank Screen', and `Don't Blank' (in addition to the
306 historical `Random Screen Saver').
307 * Configure now defaults to installing the hacks in
308 <prefix>/lib/xscreensaver/ instead of <prefix>/bin/.
309 (Most distros already did it this way.)
310 * New GL hacks, `menger', `engine', `flipscreen3d'.
311 * Made `sierpinski3d' be more colorful.
312 * New versions of `xmatrix' and `nerverot'.
313 * Fixed a bug in `starwars' that made the font be drawn
314 with thin lines in -root mode.
315 * Fixed a bad colormap bug in `crystal' that could make
316 *subsequent* hacks malfunction!
317 * Made `gflux' able to grab screen images (`-mode grab').
318 * Updated `webcollage' for recent search engine changes.
319 * Removed most command-line options to `xscreensaver':
320 just edit the ~/.xscreensaver file instead.
321 * Improved behavior on multi-screen and Xinerama systems:
322 the mouse now stays on the screen where the user left
323 it, and the password and splash dialogs always appear
324 on the screen that has the mouse.
325 * Made the splash dialog use more Gtk-like colors;
326 made it have only two buttons, "Settings" and "Help".
327 * Made `sonar' understand `.ssh/known_hosts2' format
328 files, and be better about stripping out illegal
330 Changes since 3.33: * Turned `memoryLimit' off by default, sigh. Apparently
331 some versions of the GL libraries (appear to) allocate
332 hundreds of megs for every GL program, so `memoryLimit'
333 was causing GL programs to malfunction or crash on
335 * Improved fading on TrueColor XFree86 4.1.x systems.
336 * New GL hack, `circuit'.
337 * Added `fuzz' mode to `decayscreen'.
338 * New version of `whirlygig'.
339 * Added links to `xplanet' and `sphereEversion'.
340 * Fixed rare race condition that could make `sonar' hang.
341 * Fixed potential crash in `speedmine'.
342 * Made `xscreensaver-demo' not crash when imageDirectory
343 was set to a non-existent directory.
344 * Made `xscreensaver-getimage-video' invoke XawTV's
345 `streamer' program better.
346 * Made `phosphor' and `starwars' deal with CR, LF,
347 or CRLF line endings.
348 * Changes for Cygwin compilation environments.
349 * Made `sonar' compile on systems that can't ping.
350 * Configure changes for HPUX 10.20.
351 * Made PAM code work on Red Had 4.2 systems.
352 * Made `xscreensaver-command -deactivate' work when the
353 saver is not active: what that does is reset the idle
354 timer, as if keyboard input had been detected. This
355 was added for the benefit of people writing DVD-playing
356 software: they can now prevent the screensaver from
357 kicking in by sending a -deactivate message once a
358 minute while the movie is playing and not paused.
359 * Various minor portability tweaks.
360 Changes since 3.32: * New hacks, `speedmine' and `whirlygig'.
361 * Sped up `pyro', made the explosions look a bit better.
362 * Added better stars to `glplanet' and `starwars'.
363 * Many internal changes to `webcollage'.
364 * Some new options to `attraction'.
365 * Minor fix to `noseguy' to avoid un-erased pixels.
366 * Rewrote the screen-eraser effects so that they complete
367 in the same amount of time regardless of how slow
368 your X server is (some of them were glacial on servers
370 * Fixed a potential free memory reference that could
371 sometimes cause a crash at startup.
372 * Possibly fixed a problem that could cause the daemon
373 to crash with an X error. I was never able to
374 reproduce this problem, but I think I might have
375 figured out what caused it.
376 * Worked around a problem that caused PAM authentication
377 to fail on some Red Hat 7.x systems.
378 * Added a `memoryLimit' parameter that controls the
379 amount of memory a graphics hack may allocate: if they
380 try to allocate more than this, malloc() will fail
381 (and they will exit or (safely) crash, rather than
382 hogging memory.) Default is 50M.
383 * Made `gnome-help-browser' be the default way to display
384 man pages in `xscreensaver-demo', if running on a
386 Changes since 3.31: * The image-manipulating hacks (`slidescreen', etc.) can
387 now operate on randomly chosen image files from disk,
388 or on frames captured from the system's video input,
389 instead of (or in addition to) manipulating images of
391 * Rewrote `vidwhacker' to use the new image-grabbing
393 * Made fading work on TrueColor XFree86 4.x systems.
394 * Fixed a subtle rendering bug in `atlantis' (the fish
396 * Made `atlantis' have a texture simulating light
397 reflections from the surface of the ocean.
398 * Fixed up label placement in `molecule'.
399 * Better color bars in `xteevee'.
400 * Made `install-strip' not try to strip scripts.
401 Changes since 3.30: * Put in more sensible defaults for DPMS, and updated
402 the documentation to reflect the fact that all your
403 DPMS settings are now belong to xscreensaver.
404 * Fixed the `xscreensaver.spec' file so that `--force'
406 * New versions of `rotzoomer' and `nerverot'.
407 * Fixed an OSF/1 compilation problem in `molecule'.
408 Changes since 3.29: * New hacks, `molecule', `dangerball', and `rotzoomer'.
409 * New version of `gflux'.
410 * Made `gltext' able to display the current time.
411 * Fixed a floating-point-precision problem in `gltext'
412 that sometimes caused horizontal lines to vanish.
413 * Removed the `-window-id' option from the hacks:
414 it never worked right, and was unnecessary.
415 * Made the `starwars' hack use thicker lines, antialias
416 the text, and fade out at the far edge instead of just
418 * Fixed an SHM segment leak in `moire'.
419 Changes since 3.28: * Better rendering of the new logo.
420 * New hack, `gltext'.
421 * Added `-planetary' option to `gears', to draw a
422 different kind of gear system.
423 * Made motion and rotation be smoother in `gears',
424 `glplanet', `moebius', `rubik', and `sierpinski3d'.
425 * Improved coloration in `sierpinski3d'.
426 * Made the GL hacks react to window size changes.
427 * Made most of the GL hacks take a -fps option (like
428 `pulsar' did), so you can use them to benchmark your
430 * Fixed the previous fix to `sonar'.
431 * Minor fix to `nerverot'.
432 Made sonar able to ping hosts on DEC OSF1.
433 * Eliminated a bogus "didn't get enough colors" warning
434 in some of the hacks.
435 Changes since 3.27: * New logo for xscreensaver!
436 * New hacks, `starwars' and `stonerview'.
437 * Made the motion of the bouncing ball in `stairs' be a
439 * Made newly-added screenhacks be added to .xscreensaver
440 automatically: if there are hacks in the app-defaults
441 file that are not also in ~/.xscreensaver, they will
442 be added to the end of the list.
443 * Redid the `Screensaver Options' part of the control
444 panel; xscreensaver now lets you configure your DPMS
446 * Fixed some Makefile problems with non-GL builds.
447 * Fixed detection of MesaGL for version 3.3.
448 * Better workaround to Red Hat 7.0's broken gcc.
449 * Added Sparc Solaris kernel panic to `bsod'.
450 Changes since 3.26: * New hacks: `zoom' and `whirlwindwarp'.
451 * Fixed a free-memory-reference bug in `sonar'.
452 * Better error handling when there are no suitable GL
454 * Added diagnostic dialog when xscreensaver-demo is
455 unable to launch xscreensaver (e.g., when running as
457 * Fixed a bug that caused screenhack argument changes
458 to be ignored when xscreensaver-demo was running as
459 root (if "root" and "nobody" have different home
461 * Made the programs default to ":0" if $DISPLAY is unset.
462 * Made the `-verbose' output include information about
463 which server extensions were supported at compile time.
464 * Worked around Red Hat 7.0's broken gcc 2.96.
465 * Updated default delays on the GL hacks to look better
466 on machines with super-fast 3D hardware.
467 * Install `screensaver-properties-capplet' to work around
468 the usual egregious GNOME lossage.
469 Changes since 3.25: * Added "enabled" checkboxes in the list of hacks in
470 xscreensaver-demo (Gtk version only.)
471 * New hacks `hyperball', `xrayswarm', and `gflux'.
472 * New versions of `nerverot', `galaxy', and `hypercube'.
473 * Small fixes to `phosphor', `shadebobs', `xflame',
475 * Added external helper program `xscreensaver-gl-helper'
476 to figure out which X visual to use for OpenGL
478 * Configure updates for XFree86 4.0, and for BSD.
479 * Made it be more tolerant of bogus /etc/group files.
480 * When installing the PAM config file, first try to just
481 copy an existing "xdm" or "login" config file, so that
482 xscreensaver does authentication in the same way as the
484 Changes since 3.24: * New hack, `nerverot'.
485 * Added BSD kernel panic to `bsod'.
486 * New version of `shadebobs'.
487 * New version of `petri'.
488 * Updated `webcollage' to handle recent Altavista URL
489 format changes; made it search the AP photo gallery.
490 * Revamped command-line options of `sonar' and made it
491 properly handle subnets.
492 * The `bubbles' hack can now trickle up or down the
494 * The `xsublim' hack can now read its text from programs.
495 * Support for GLE version 3 in `extrusion'.
496 * Fixed compilation problems in `maze'.
497 * Fixed a rare crash in `flow'.
498 * Fixes for minor installation problems.
499 Changes since 3.23: * Added `-ignorant' option to `maze' hack.
500 * Updates to `critical', `bsod', `xflame', and `flow'.
501 * Added support for Kerberos 5 (via its Kerberos 4
502 compatibility layer.)
503 * Fixed a bad leak in `xteevee'.
504 * Updated `webcollage' to handle recent Altavista URL
506 * Removed xscreensaver-demo's `Ok' and `Cancel' buttons,
507 since they were confusing people: all changes are now
509 * Made xscreensaver-demo install itself into the Gnome
511 Changes since 3.22: * Fixed some misplaced text fields in the Motif version
512 of xscreensaver-demo; fixed a crash in the Gtk version
513 that would happen if the programs list was empty.
514 * Fixed a recently-introduced bug in `pulsar'.
515 * Made `sierpinski3d' use solid tetrahedrons instead of
517 * Added `-trace' option to `xmatrix'.
518 * Added new hacks `xteevee' and `xspirograph'.
519 Changes since 3.21: * Fixed some bugs in xscreensaver-demo.
520 * Rewrote the Motif version of xscreensaver-demo to
521 match the new Gtk version.
522 * The Athena toolkit is no longer supported.
523 Changes since 3.20: * Tweaked the xscreensaver-demo UI (Gtk only.)
524 * Fixed a few visual selection bugs. I think the proper
525 GL visual should be used with nVidia systems now.
526 * Made the Makefiles obey $install_prefix.
527 * Made the `xscreensaver.spec' file able to generate both
528 GL and non-GL packages simultaneously.
529 Changes since 3.19: * Added new hacks `ripples' and `sierpinski3d'.
530 * Made `xscreensaver-command -exit' be silent when no
531 screen saver was running (instead of complaining.)
532 * Made `webcollage' and `vidwhacker' use `xloadimage'
533 when available (in addition to `xli' and `xv'.)
534 * Improved memory usage in `petri' and gave it a hard
535 cap on how much memory it can allocate.
536 * Added `-watch' option to `xscreensaver-command'.
537 * Made `xscreensaver-demo' come up with the
538 most-recently-run hack selected by default.
539 * Rewrote the Gtk version of `xscreensaver-demo'.
540 It's a lot easier to use now.
541 * Extended the format of the programs list in the
542 .xscreensaver file, for the benefit of the new
543 capabilities of `xscreensaver-demo'.
544 NOTE: you might want to delete your ~/.xscreensaver
545 file and allow it to be re-created! The old one
546 should still work, but xscreensaver-demo won't be as
548 Changes since 3.18: * Fixed gcc dependencies in `bumps' and `ccurve'.
549 * New hack, `extrusion'.
550 * Some of the web sites that `webcollage' was using as
551 its sources changed formats; tweaked it to understand
553 * Added typeahead in the password dialog: if the screen
554 is locked, and you unlock it by typing a character,
555 that key will be automatically inserted in the
556 password dialog (unless it is Return, Enter, Space,
557 or a non-printing key like Shift.)
558 * Made `xmatrix' take a `-small' option, since some
559 folks with tiny screens prefer a smaller font.
560 Changes since 3.17: * New versions of `shadebobs', `lmorph', and `distort'.
561 * Added `ccurve', `blaster', and `bumps' hacks.
562 * Replaced `forest' hack with a rewritten version.
563 * Worked around a Xinerama server bug.
564 * Fixed a bug I introduced in 3.10 that caused some
565 hacks to print out superfluous warnings about not
566 having gotten enough colors.
567 * Made `sproingies' obey the `-delay' option.
568 * Fixed a portability bug in `shadebobs'.
569 * Made `webcollage' and `vidwhacker' use `xli' in
570 preference to `xv', if it is available.
571 * Added a new source of images to `webcollage'.
572 * If running under KDE, xscreensaver will add itself to
573 KDE's list of screensavers (via xscreensaver.kss.)
574 * Improved detection of GL libraries.
575 * Made the password dialog include the date and time.
576 Changes since 3.16: * New version of `webcollage' -- deals better with
577 corrupted images, and can use an http proxy.
578 * New hack, `xsublim' (run it in the background,
579 rather than adding it to the programs list.)
580 * The xscreensaver daemon was leaking a file descriptor
581 each time you edited your .xscreensaver file. Fixed.
582 Changes since 3.15: * New version of `shadebobs'.
583 * Improved image selection in `webcollage', and sped it
585 * Made configure find the right version of perl.
586 * Rewrote the CGI part of `webcollage'.
587 * `make clean' was deleting some things it shouldn't.
588 * Fixed a typo in the default programs list.
589 Changes since 3.14: * Added `webcollage' and `shadebobs' hacks.
590 * Added a `-stdout' arg to `vidwhacker' so that it can
591 be used in a pipeline.
592 * Made `petri' use less memory.
593 Changes since 3.13: * Various improvements to the Gtk port.
594 * Turned off PAM by default on Solaris, since PAM seems
595 generally to be misconfigured out-of-the-box.
596 * Made the `--without-gtk' configure option work.
597 * Made configure check the Gtk version number, since it
599 * Fixed a bug in the code that attempted to prevent
600 changes of screen resolution while the screen is
602 * Fixed a race condition in `xscreensaver-demo' that
603 could cause an X error at startup.
604 * Added `-transparent' option to `deluxe'.
605 * Added `petri' hack.
606 Changes since 3.12: * Ported `xscreensaver-demo' to Gtk.
607 * Made it possible to build Motif, Gtk, and Athena
608 versions of `xscreensaver-demo' in the same directory
609 without reconfiguring.
610 * Made `xscreensaver-demo' chase symlinks before writing
611 the .xscreensaver file, so that if .xscreensaver is
612 itself a symlink, the underlying file will be replaced
614 * Some Makefile and configure tweaks for Solaris and
616 * Made it possible to set the fire color in `xflame'.
617 * Made transparency work in TrueColor (for `goop' and
619 * Fixed a multi-head bug introduced by the virtual
621 Changes since 3.11: * Made it so that you can't scroll the screen while the
622 lock dialog is up (with XFree86 virtual viewports.)
623 * Fixed a bug in `flag' that caused bob's chin to get cut
624 off after a few iterations.
625 Changes since 3.10: * Made `xjack' be black-on-white-ish, so that it looks
626 less like a computer screen and more like the
627 typewritten paper it's supposed to be.
628 * New version of `pulsar'.
629 * Fixed Solaris compilation problem in `phosphor'.
630 * Made xscreensaver notice XFree86's virtual root window
631 hack, so that if the X server's root window is larger
632 than the monitor's displayable resolution, the screen
633 saver will limit itself to the area that actually
634 appears on the screen.
635 * Made the xscreensaver daemon do a better job of
636 picking the visual class that should be used for GL
637 programs. Less user intervention should be needed
638 now: you can use the logical visual name `GL' instead
639 of having to figure out by hand which one to use.
640 * Oops, the visual was defaulting to "best" instead of
641 "default", because the .xscreensaver file was not being
642 loaded quite early enough.
643 * Made configure figure out how to build icmp ping
644 support into the `sonar' hack automatically.
645 * Made warnings about not being able to read shadow
646 passwords not be printed if compiled with PAM support.
647 * Improved PAM startup diagnostics.
648 * Worked around the Solaris PAM bug that was causing
649 crashes there, so now PAM is turned on by default.
650 * Made configure detect the number of arguments that
651 pam_strerror() takes, since on Linux, this apparently
652 changed between 2.0 and 2.2, sigh.
653 * Made the /proc/interrupts kludge look for "PS/2 Mouse"
654 as well as "keyboard".
655 * Made xscreensaver notice when there has been a sudden
656 large jump in wall-clock time, and if so, lock right
657 away, instead of waiting for "lockTimeout" to expire
658 first. (Laptops need this for safer recovery from
660 * Added `-throttle' option to `xscreensaver-command'.
661 Changes since 3.09: * Added `phosphor', `xmatrix', and `pulsar' hacks.
662 * Fixed a bug in the color allocator that sometimes
663 caused `starfish' to fall back to monochrome.
664 * Reduced the amount of code that runs before root
665 privileges are disavowed: "normal" and "shadow"
666 passwords now do some initialization as root, but the
667 PAM and Kerberos authorization schemes will be
668 initialized while running as "nobody". Supposedly
669 this closes a potential security hole when using
671 * Added some more sanity checking to configure.
672 Changes since 3.08: * Added `compass', `squiral', `xflame', `wander',
673 `spotlight', and `critical' hacks.
674 * Added some new modes to `decayscreen'.
675 * Made `deluxe' work in monochrome.
676 * Generalized usage of the Double-Buffer server extension
677 in several hacks (`compass', `deluxe', `interference',
678 `kumppa', and `moire2'.)
679 * Fixed another visual-depth problem in `rd-bomb'.
680 * The screen saver will now defer blanking if neither
681 the keyboard nor the mouse could be grabbed. Instead,
682 it will just try again in a few minutes. This fixes
683 a bad interaction between xscreensaver and programs
684 like VMware that hold the mouse and keyboard grabbed
686 * Added a new erase mode (expanding spiral.)
687 Changes since 3.07: * Fixed some bugs in my port of `t3d'.
688 * Added `penetrate' and `deluxe' hacks.
689 * When linking against Motif 2.x, also link against XPM.
690 * Added support for using /proc/interrupts for idle
691 detection on Linux. Now xscreensaver shouldn't kick
692 in when the user is active on a non-X virtual console.
693 * Upgraded to autoconf 2.13.
694 Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
695 in properly; check for _Xsetlocale in -lXintl.)
696 * Portability fixes for sonar.c.
697 * Fixed a compilation problem when you have GL but don't
699 * Made configure notice when MesaGL requires -lpthread.
700 * Made `flame' ignore SIGFPE (not sure if this is the
701 right fix; it seems only to be needed on FreeBSD.)
702 * Kludged `rd-bomb' work on visuals that are of depth 24
703 but that *do not* support pixmaps of depth 32.
704 * Fixed `halo' to work properly in TrueColor.
705 * Changed `xscreensaver.spec' to install the hacks in
706 /usr/X11R6/lib/xscreensaver/ by default, since that's
707 where recent Red Hat distributions put them.
709 * Updated versions of `crystal', `hopalong', and `flow'
711 * Imported `demon' and `loop' modes from xlockmore.
712 Changes since 3.05: * Oops, the "default-n" visual descriptor was broken;
713 it was always installing a colormap if the
714 `installColormap' preference was set, meaning that
715 `xearth', `xv' and friends were using the wrong
716 colors on 8-bit systems.
717 * Turned off HAVE_PING in `sonar', since it compiles
718 on some Linux systems, but not others of similar
720 Changes since 3.04: * Fixed an off-by-1 in `distort'.
721 * Added `sonar' hack.
722 * New version of `glplanet' (with stars.)
723 * Made all hacks exit when you type `q' or `ESC' at them,
724 and made them obey the WM_DELETE_WINDOW ClientMessage.
725 * Fixed a nonfatal buffer overrun in lament (note:
726 lament still doesn't work with MesaGL 3.0: it dies in
727 lambda_textured_triangle1(), which is Mesa's bug, not
729 Changes since 3.03: * Added an `xscreensaver.spec' file, to make it easier
730 for other folks to generate RPMs.
731 * Made the password code work on HPUX in the situation
732 where: ``enhanced security'' is available; but not
733 used; but the user typed a password more than 8
734 characters long anyway. FTSOHPUX.
735 Changes since 3.02: * Made locking work when passwd aging is enabled.
736 * Added support for PAM (Pluggable Authentication
737 Modules.) It is still turned off by default, though,
738 since it doesn't seem to work on Solaris 2.6, and has
739 been behaving erratically on Red Hat 5.1.
740 * Made each possible authentication method be tried in
741 turn until one succeeds; this means that Kerberos is
742 being used, we will first check Kerberos, and if that
743 fails, will then consult the local password file.
745 * Save and restore the bits under the passwd dialog,
746 to avoid leaving a black rectangle behind when
747 unlocking is cancelled.
748 Changes since 3.01: * Not everyone has sys/select.h, sigh...
749 Changes since 3.00: * Some fixes to `reflect'.
751 * Made it log unsuccessful attempts to unlock the screen
753 * Fixed a bug where `xscreensaver-demo' could be seeing
754 a different programs list than `xscreensaver' did.
755 Changes since 2.34: * The xscreensaver daemon no longer links against Motif
756 or Athena: demo-mode and the preferences panel are no
757 longer built in to the daemon, but are now handled by
758 an external program, `xscreensaver-demo'.
759 (I decided that this, along with the recent addition
760 of the `.xscreensaver' config file, justified bumping
761 the version number to 3.00, since this is a fairly
762 major architectural change.)
763 * Lines in the `*programs' resource may now begin with
764 the character "-", meaning "don't run this hack."
765 In this way, it's possible to disable a hack without
766 throwing away the information about it (making it
767 easier to change your mind later.) Eventually the
768 preferences/demo mode GUI should represent this as a
769 checkbox or something.
770 * Fixed a short race condition where it was possible for
771 xscreensaver to die with a BadWindow error if it was
772 blanking the screen just as another window was being
774 * Made it possible to disable specific modes in `bsod'.
775 Changes since 2.33: * Fixed a bug that was making `pipes' generate way too
776 many valves. Made the viewpoint in `pipes' be selected
777 randomly instead of always being -10 degrees.
778 * Fixed a bug in the XSHM code, in the case where the
779 server supports the XSHM extension but is not the same
780 machine as the client.
781 * Made `rd-bomb' default to taking up the whole screen.
782 * Made it not try to do fading/unfading if no PseudoColor
784 * Initial attempt at supporting VT-locking (doesn't work
786 * Eliminated the `captureStdout' resource; now
787 `captureStderr' controls both streams.
788 * Added `-capture-stderr' and `-no-capture-stderr'
789 command-line arguments.
790 * Added `glplanet' hack.
791 * When a hack is selected with `xscreensaver-command
792 -select', that hack will be used until further notice
793 (until the saver turns off, or another activation
795 Changes since 2.32: * Made `xscreensaver-command' print error messages:
796 the xscreensaver daemon now responds to ClientMessage
797 events by writing a response message on a window
798 property, instead of just writing to its stderr.
799 * Made the ~/.xscreensaver file be automatically reloaded
800 when the file date changes.
801 * The password dialog and splash screen no longer depend
802 on Motif or Athena. This should clear up a number of
803 focus problems, and is the first step on the path
804 toward moving all of the Motif/Athena/whatever code
805 out of the xscreensaver daemon, and into external
807 * Don't complain about LessTif 0.86 any more, since the
808 new password dialog makes that problem go away.
809 * Configure tweaks for Irix 6.5, SunOS 5.something.
810 * New `-reflect' option to `distort'.
811 Changes since 2.31: * Added reading and writing of a ~/.xscreensaver file,
812 so that the Preferences panel can save its settings.
813 * New version of `rubik'.
814 * Added `-select N' argument to `xscreensaver-command'.
815 * Oops, left out some of the `bubbles3d' files...
816 Changes since 2.30: * The cursor was invisible in the password dialog. Fixed.
817 * Made configure warn against MesaGL 2.6.
818 * Fixed X error at startup when using non-default visual.
819 * New version of `crystal', `ant', and `atlantis' from
821 * New hack, `bubble3d'.
822 * Added some new modes to `bsod'.
823 Changes since 2.29: * Changed the order in which -lSM and -lICE are linked
824 to be after Motif instead of before (Lesstif on Irix
826 Changes since 2.28: * Work around a bash bug in configure.
827 * Tweaked HPUX paths again. FTSOHPUX.
828 * Made configure recommend against LessTif 0.86, due
829 to a bug in that version that causes a security hole
830 in the screen locking code. LessTif 0.87 will fix it.
831 * Made all of the `--with' options to `configure' accept
832 a directory option as well (so that --with-motif=/FOO
833 will add -I/FOO/include -L/FOO/lib). I believe this is
834 the Configure Party Line of how do to such things.
835 * Fixed a bug where the mouse was left un-grabbed
836 after the first time the graphics hack was changed
837 (simplified all of the mouse-grabbing logic.)
838 * Maybe possibly perhaps made `vidwhacker' really not
839 leave stray xv windows around. This time for sure.
840 * Added a new erase mode (random dots fizzling out.)
841 * Added `-prefs' argument to `xscreensaver-command',
842 that brings up the Preferences dialog directly (it
843 seems that nobody ever noticed the `Preferences' button
844 on the Demo Mode dialog, maybe this will help.)
845 * Added a splash screen. Turn it off with *splash:false.
846 Changes since 2.27: * Better macsbug text in `bsod'.
847 * New version of `distort' with many new modes.
848 * Plugged a leak in `coral'.
849 * Tweaked configure for HPUX.
850 * Removed some compiler warnings.
851 * More consistent usage of stderr versus stdout.
852 * More diagnostics should an X error occur.
853 * Fixed a possible crash in SGI-specific unfading code.
854 Changes since 2.26: * Improved version of `distort'.
855 * Made `lament' compile against OpenGL 1.0 (though it
856 still requires 1.1 to work properly.)
857 * Updated my email address and home page.
858 Changes since 2.24: * Improved motion in `rd-bomb'.
859 * Added XSHM (shared memory extension) support to the
860 `distort', `interference', `moire', `rd-bomb', and
861 `swirl' hacks, which speeds them up a bit.
862 * Added `lament' hack.
863 Changes since 2.23: * Tweaked the order of the -L options again.
864 * Cleaned up configure's `--help' message.
865 * Added `kumppa' hack.
866 * Smarter maze-solving algorithm in `maze'.
867 * Took `xlyap' out of the default list of hacks, since
868 it's just incredibly buggy (and slow.) Maybe someday
869 someone will fix it...
870 * Added `distort' hack, but didn't add it to the default
871 list (yet) because it's still too slow.
872 * Made the Athena demo dialog look more like the Motif
873 version; it has a text-entry field now, too.
874 * Made the Athena password dialog echo asterisks, like
875 Motif does, instead of using a flyspeck font.
876 * Some random configure tweaks.
877 * Added a `timestamp' resource that makes the `-verbose'
878 messages include the time at which they were printed.
879 Changes since 2.22: * The fix for SGI's ``scheme'' nonsense broke things, and
880 let the user's "*background" resource show through.
881 Fixed it in a different way.
882 Changes since 2.21: * Added support for the DPMS server extension (Display
883 Power Management System.)
884 * Made configure advertize the `--enable-subdir' option a
885 little more, since that seemed to cause some people
886 stress. Also, made that directory be built into the
887 xscreensaver executable, as a hardcoded prefix to
888 $PATH. (Might help, shouldn't hurt.)
889 * Made configure prefer the two-arg gettimeofday to the
890 one-arg version, since AIX doesn't have any prototypes.
891 * Made it work with Xaw3d (the 3D Athena library.)
892 * Made `make install' create directories as necessary.
893 * New version of lmorph from Sverre.
894 * Added `crystal' and `discreet' hacks from xlockmore.
895 * Added a new mode to `bsod'.
896 Changes since 2.20: * Made `xscreensaver-command -time' use different words.
897 (It now describes the two states as "screen blanked
898 since..." and "screen non-blanked since..." instead of
899 "active since..." and "inactive since..." which a lot
900 of people interpreted as meaning the opposite of what
902 * Improved some error messages, in the hopes of making
903 the distinction between the xscreensaver and
904 xscreensaver-command programs more obvious.
905 * Rewrote (and reorganized) parts of the xscreensaver and
906 xscreensaver-command manual pages.
907 * Renamed xscreensaver's `-lock' command-line option to
908 be `-lock-mode', to avoid confusion with the `-lock'
909 option to xscreensaver-command, which does a totally
911 * Removed xscreensaver's `-demo' command-line option for
912 a similar reason; use `xscreensaver-command -demo'
914 * Disabled SGI's ``scheme'' nonsense in a better way than
915 fully-qualifying the background colors in every single
917 * Fixed some other minor cosmetic problems when *sgiMode
919 * Fixed an X error in `bsod -root' (how ironic...)
920 Changes since 2.19: * Fixed a bug that caused the mouse to sometimes not be
921 grabbed properly (meaning the window manager menu could
922 pop up over the demo-mode display.)
923 * Fixed a bug that made the stderr output sometimes get
925 * Fixed a bug that made the demo-mode scrollbar move too
927 * Protected against a possible buffer overflow.
928 * Made `vidwhacker' not leave stray xv windows around.
929 * New version of `ant' so that Bagley doesn't calve.
930 * Make configure on AIX get XShm from the right library.
931 Changes since 2.18: * One file was missing from the tar file. Fixed.
932 Changes since 2.17: * Oops, atlantis wasn't being built by default. Fixed.
933 * Added `epicycle' hack.
934 * Added `interference' hack.
935 * Added `truchet' hack.
937 * Added some new modes to `vidwhacker'.
938 Changes since 2.16: * Added a -window-id argument to most hacks, so that they
939 can draw on arbitrary externally-provided windows.
940 * Synched with xlockmore 4.11a01.
942 * Added `atlantis' GL hack.
943 * Renamed `puzzle' hack to `jigsaw', since xlock already
944 had a different mode called `puzzle'.
945 * Made it self-configure properly when Motif 2.1.0 is
946 being used (requires -lXp now, sigh...)
947 Changes since 2.15: * Made `flag' able to do XPM images.
948 * New look for the xscreensaver logo (`xroger').
949 * Fixed compilation error on Suns with adjunct passwords.
950 * Got multi-architecture builds working again.
951 * Some configure tweaks for building on HPUX and Solaris.
952 * Fixed bug in decayscreen.
953 * Fixed typo in passwd.c.
954 * Made `cynosure' not die when colormap is full.
955 Changes since 2.14: * Added `cynosure' hack.
956 * Added `moire2' hack.
957 * Tweaked `erase.c' some more.
958 * Made unfading a bit smoother.
959 * Added `vidwhacker' hack (not installed by default.)
960 * Added `stairs' hack.
961 * Split `escher' into `cage' and `moebius', as per
963 * Changed subprocess handling to use sigaction() instead
964 of signal() if it's available (this is necessary for
965 SCO but should work fine on other systems too.)
966 * Various other tweaks.
967 Changes since 2.13: * Better fix for the Motif drag-and-die lossage.
968 * Put in some kludges to work around a LessTif bug.
969 * XScreenSaver is known to work with LessTif 0.82 now.
970 * Made fading work on high-end SGI video hardware.
971 * Fixed another SGI-specific bug in screen grabbing;
972 will the madness never cease?
973 * Fixed another crash in `xlyap'.
974 Changes since 2.12: * Made `decayscreen' do directions other than down.
976 * Fixed a crash in `xlyap'.
977 * Added CDE info to the man page, removed `cde.txt'.
978 * Configure tweaks for Zippy.
979 * Turned off the signal handling in `bubbles' because
980 it was sometimes failing to die.
981 * Added `hacks/xscreensaver-sgigl.c' to make it possible
982 to run SGI's ElectroPaint hack (/usr/demos/bin/ep)
983 with xscreensaver. Finally!
984 * Fixed a buffer overrun in the locking code that some
985 wily, malicious cracker must have slipped in.
986 * Disabled Motif drag-and-drool in the dialog box
987 buttons, since it's broken in some old versions of
989 Changes since 2.11: * Added `README.debugging'.
990 * Added `puzzle' hack.
