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 160 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 4.12: * On Xinerama systems, xscreensaver now runs one hack on
80 each monitor (just like in "real" multi-head mode)
81 instead of running one hack stretching across all the
82 screens. Note that for this to work with any 3rd party
83 screensavers, they must update their "vroot.h" file.
84 * `webcollage' and `vidwhacker' display images using
85 `xscreensaver-getimage' now.
86 * Added `ljlatest' script for use with `starwars' and
88 Changes since 4.11: * New GL hacks, `flipflop', `antspotlight', and
90 * Added VMS to `bsod'.
91 * Compile without warnings in "gcc -pedantic".
92 * Updates to `webcollage' and `queens'.
93 * Fixed a bug that could cause PAM to hang.
94 Changes since 4.10: * New hacks, `hypertorus', `cubestorm', `glknots',
95 `blocktube', and `glmatrix'.
96 * Updates to `cloudlife', `engine', `xmatrix', and
98 * Rewrote `glslideshow': it should work on somewhat
99 wimpier video cards now.
100 * Various portability tweaks.
101 Changes since 4.09: * New hacks, `cloudlife' and `klein'.
102 * Added Apple ][+, HPUX, and OS/390 sessions to BSOD.
103 * Added some Matrix Reloaded text to `xmatrix'.
104 * Updates to `webcollage', `eruption', `jigglypuff',
105 `metaballs', and `endgame'.
106 * Completely ignore the `memoryLimit' setting now,
107 since it was still causing people GL grief.
108 * Various minor fixes.
109 Changes since 4.08: * New hacks, `flyingtoasters', `bouncingcow',
110 `jigglypuff', and `glslideshow'.
111 * More models in `engine'.
112 * Rewrote `xscreensaver-getimage' to remove reliance on
113 external image loaders (xv, chbg, xloadimage, etc.)
114 and to reduce flicker when loading files.
115 * Made `gflux' and `flipscreen3d' be mouse-spinnable.
116 Changes since 4.07: * New hacks, `atunnels' and `piecewise'.
117 * Physics improvement in `fluidballs'.
118 * Various fixes for XDarwin systems (X11 on MacOS X.)
119 * Added -clock option to `barcode'.
120 * Minor fixes to `endgame', `flurry', `flipscreen3d',
122 Changes since 4.06: * New hacks, `flurry', `metaballs', `eruption',
123 `popsquares', and `barcode'.
124 * Minor updates to `maze' for high density mazes.
125 * Added double buffering to `fluidballs' and `whirlygig'.
126 * Bug fixes for running xscreensaver to a remote XFree86
127 display (which nobody would ever do...)
128 * Updated `webcollage' (faster Alta Vista searching.)
129 * Updated `glplanet' so the sun sets in the west.
130 * Updated `sproingies' with smooth, unsegmented surfaces.
131 * Fixed Perl version-sensitivity in
132 `xscreensaver-getimage-file'.
133 * Fixed GTK2 scrolling bug in `xscreensaver-demo'.
134 Changes since 4.05: * New hack, `glblur' (disabled by default, since it
135 requires fast OpenGL texture support.)
136 * New hack, `halftone'.
137 * Updates to `endgame', `queens', `bumps', `glplanet',
138 `engine', and `circuit'.
139 * New version of `menger' that uses far fewer polygons.
140 * Fixed minor bug in `critical' that could cause some
141 bogus X servers to crash.
142 * Better labels in `molecule': the labels now appear to
143 be attached to the atoms, instead of floating in front
145 * Fixed bug that could rarely cause GL hacks to fail to
146 double-buffer (causing intermittent flickering.)
147 * Fixed a relative-URL-parsing bug in `webcollage'.
148 * Fixed a bug that (sometimes) caused the window manager
149 close box to kill `xscreensaver-demo' with a crash
150 instead of a graceful exit.
151 * Updated xscreensaver.pam to the Red Hat 7.3 way.
152 * More Gnome2-related configure crap.
153 * Updated to latest `config.guess' and `config.sub'.
154 * Fixed occasional core dump in `distort'.
155 * Added a Linux fsck failure and kernel panic to `bsod'.
156 * Added MacOS X kernel panic to `bsod'.
157 * Fixed a bug in `bsod' (all bsod bugs are ironic.)
158 * Fixed a bug that caused `xscreensaver-gl-helper' to
159 print a nonsense visual ID with some versions of
160 `printf': this could cause GL programs to display
161 incorrectly (e.g., flickery.)
162 Changes since 4.04: * More `configure' tweaks to try and get things working
163 on systems that both Gtk 1.x and 2.x installed.
164 * New hack, `endgame'.
165 * Minor updates to `gltext'.
166 Changes since 4.03: * Support for GTK 2.x / GNOME 2.x.
167 * The `configure' script will now use `pkg-config' if
168 you have it, in preference to `gtk-config', etc.
169 * New hacks, `lavalite', `queens', and `anemone'.
170 * Minor updates to `spheremonics', `gltext', `xmatrix'.
171 * You can use the mouse to manually spin most of the GL
172 hacks now (when they are displaying in a window.)
173 * Fixed a bug in `webcollage' (due to recent Alta Vista
174 url changes) that was causing it to try and load
175 incorrect image URLs.
176 * Made `xscreensaver-getimage' use gdk_pixbuf if it is
177 available: this means that those hacks that load images
178 will no longer rely on "xv", "xloadimage", etc. This
179 will close a race condition that could sometimes cause
180 your desktop background to be changed; and also makes
181 it possible for those programs to operate on image
182 files when running in windowed mode.
183 * `webcollage' can now be used in conjunction with
184 `driftnet' to display images snooped from your local
185 ethernet instead of obtained from search engines.
186 * Added man pages for all the hacks that didn't have
188 Changes since 4.02: * New hack, `spheremonics'.
189 * Minor updates to `webcollage', `cage', `moebius',
190 `morph3d', `boxed', `circuit', and `helix'.
191 * `pulsar' and `extrusion' can now load texture JPEGs.
192 * `rubik' now does non-square cubes.
193 * `fluidballs' now does various sizes of balls.
194 * `menger' and `sierpinski3d' now also show polygon
196 * `molecule' displays real subscripts in the formulae.
197 * GTK internationalization/localization support.
198 * Better detection of the various versions of libxml.
199 * Upgraded to autoconf 2.53 (from 2.13.)
200 Changes since 4.01: * Plugged a few minor leaks in `xscreensaver' and
202 * New hacks, `cubenetic' and `fluidballs'.
204 * Fixed sphere projection error in `glplanet'; installed
205 a better image of earth.
206 * Added Win2K and MacOS 1 crashes to `bsod'.
207 * Put back previous (better) version of `forest' that
208 was accidentially downgraded in the last release.
209 * New version of `bumps'.
210 * Made FPS computation in GL hacks more efficient: it
211 will influence the results less, thus resulting in
212 higher (but more accurate) reported frame rates.
213 Changes since 4.00: * New hacks: `twang', `glsnake', `boxed', `sballs',
215 * New hacks `apollonian', `euler2d', `juggle',
216 `polyominoes' and `thornbird', from xlockmore.
217 * Merged recent xlockmore changes into `ant', `braid',
218 `demon', `discrete', `drift', `fadeplot', `forest',
219 `grav', `hopalong', `ifs', `laser', `lightning',
220 `lisa', `lissie', `loop', `mountain', `penrose',
221 `rotor', `sierpinski', `slip', `sphere', `spiral',
222 `strange', and `vines'.
223 * Fixed the `gltext' bug that sometimes caused
224 horizontal lines to vanish again. This time for sure.
225 * Sped up `webcollage' by adding a C helper program to
226 replace the PPM pipeline. It also pastes images
227 semi-transparently now.
228 * Added support for the gdk_pixbuf library: if this lib
229 is available, then `blitspin', `xflame', and `flag'
230 can load GIF, JPEG, and PNG images in addition to XPM
232 * Fixed a rare race condition where the desktop-grabbing
233 hacks could sometimes leave the screen wedged, if the
234 user moved the mouse exactly when they were grabbing
235 the screen image (it would un-wedge the next time the
236 saver timed out or was activated.)
237 * Fixed incorrect colors in the screen-grabbing GL hacks
238 (`gflux' and `flipscreen3d'.)
239 * Made SIGHUP restart the daemon process (though using
240 `xscreensaver-command -restart' is still the preferred
242 * Tweaks to `xspirograph'.
243 * Minor configure and portability tweaks.
244 Changes since 3.34: * Redesigned `xscreensaver-demo' GUI: it now includes
245 small-preview and per-hack configuration dialogs.
246 * Added three new modes of operation: `One Screen Saver',
247 `Blank Screen', and `Don't Blank' (in addition to the
248 historical `Random Screen Saver').
249 * Configure now defaults to installing the hacks in
250 <prefix>/lib/xscreensaver/ instead of <prefix>/bin/.
251 (Most distros already did it this way.)
252 * New GL hacks, `menger', `engine', `flipscreen3d'.
253 * Made `sierpinski3d' be more colorful.
254 * New versions of `xmatrix' and `nerverot'.
255 * Fixed a bug in `starwars' that made the font be drawn
256 with thin lines in -root mode.
257 * Fixed a bad colormap bug in `crystal' that could make
258 *subsequent* hacks malfunction!
259 * Made `gflux' able to grab screen images (`-mode grab').
260 * Updated `webcollage' for recent search engine changes.
261 * Removed most command-line options to `xscreensaver':
262 just edit the ~/.xscreensaver file instead.
263 * Improved behavior on multi-screen and Xinerama systems:
264 the mouse now stays on the screen where the user left
265 it, and the password and splash dialogs always appear
266 on the screen that has the mouse.
267 * Made the splash dialog use more Gtk-like colors;
268 made it have only two buttons, "Settings" and "Help".
269 * Made `sonar' understand `.ssh/known_hosts2' format
270 files, and be better about stripping out illegal
272 Changes since 3.33: * Turned `memoryLimit' off by default, sigh. Apparently
273 some versions of the GL libraries (appear to) allocate
274 hundreds of megs for every GL program, so `memoryLimit'
275 was causing GL programs to malfunction or crash on
277 * Improved fading on TrueColor XFree86 4.1.x systems.
278 * New GL hack, `circuit'.
279 * Added `fuzz' mode to `decayscreen'.
280 * New version of `whirlygig'.
281 * Added links to `xplanet' and `sphereEversion'.
282 * Fixed rare race condition that could make `sonar' hang.
283 * Fixed potential crash in `speedmine'.
284 * Made `xscreensaver-demo' not crash when imageDirectory
285 was set to a non-existent directory.
286 * Made `xscreensaver-getimage-video' invoke XawTV's
287 `streamer' program better.
288 * Made `phosphor' and `starwars' deal with CR, LF,
289 or CRLF line endings.
290 * Changes for Cygwin compilation environments.
291 * Made `sonar' compile on systems that can't ping.
292 * Configure changes for HPUX 10.20.
293 * Made PAM code work on Red Had 4.2 systems.
294 * Made `xscreensaver-command -deactivate' work when the
295 saver is not active: what that does is reset the idle
296 timer, as if keyboard input had been detected. This
297 was added for the benefit of people writing DVD-playing
298 software: they can now prevent the screensaver from
299 kicking in by sending a -deactivate message once a
300 minute while the movie is playing and not paused.
301 * Various minor portability tweaks.
302 Changes since 3.32: * New hacks, `speedmine' and `whirlygig'.
303 * Sped up `pyro', made the explosions look a bit better.
304 * Added better stars to `glplanet' and `starwars'.
305 * Many internal changes to `webcollage'.
306 * Some new options to `attraction'.
307 * Minor fix to `noseguy' to avoid un-erased pixels.
308 * Rewrote the screen-eraser effects so that they complete
309 in the same amount of time regardless of how slow
310 your X server is (some of them were glacial on servers
312 * Fixed a potential free memory reference that could
313 sometimes cause a crash at startup.
314 * Possibly fixed a problem that could cause the daemon
315 to crash with an X error. I was never able to
316 reproduce this problem, but I think I might have
317 figured out what caused it.
318 * Worked around a problem that caused PAM authentication
319 to fail on some Red Hat 7.x systems.
320 * Added a `memoryLimit' parameter that controls the
321 amount of memory a graphics hack may allocate: if they
322 try to allocate more than this, malloc() will fail
323 (and they will exit or (safely) crash, rather than
324 hogging memory.) Default is 50M.
325 * Made `gnome-help-browser' be the default way to display
326 man pages in `xscreensaver-demo', if running on a
328 Changes since 3.31: * The image-manipulating hacks (`slidescreen', etc.) can
329 now operate on randomly chosen image files from disk,
330 or on frames captured from the system's video input,
331 instead of (or in addition to) manipulating images of
333 * Rewrote `vidwhacker' to use the new image-grabbing
335 * Made fading work on TrueColor XFree86 4.x systems.
336 * Fixed a subtle rendering bug in `atlantis' (the fish
338 * Made `atlantis' have a texture simulating light
339 reflections from the surface of the ocean.
340 * Fixed up label placement in `molecule'.
341 * Better color bars in `xteevee'.
342 * Made `install-strip' not try to strip scripts.
343 Changes since 3.30: * Put in more sensible defaults for DPMS, and updated
344 the documentation to reflect the fact that all your
345 DPMS settings are now belong to xscreensaver.
346 * Fixed the `xscreensaver.spec' file so that `--force'
348 * New versions of `rotzoomer' and `nerverot'.
349 * Fixed an OSF/1 compilation problem in `molecule'.
350 Changes since 3.29: * New hacks, `molecule', `dangerball', and `rotzoomer'.
351 * New version of `gflux'.
352 * Made `gltext' able to display the current time.
353 * Fixed a floating-point-precision problem in `gltext'
354 that sometimes caused horizontal lines to vanish.
355 * Removed the `-window-id' option from the hacks:
356 it never worked right, and was unnecessary.
357 * Made the `starwars' hack use thicker lines, antialias
358 the text, and fade out at the far edge instead of just
360 * Fixed an SHM segment leak in `moire'.
361 Changes since 3.28: * Better rendering of the new logo.
362 * New hack, `gltext'.
363 * Added `-planetary' option to `gears', to draw a
364 different kind of gear system.
365 * Made motion and rotation be smoother in `gears',
366 `glplanet', `moebius', `rubik', and `sierpinski3d'.
367 * Improved coloration in `sierpinski3d'.
368 * Made the GL hacks react to window size changes.
369 * Made most of the GL hacks take a -fps option (like
370 `pulsar' did), so you can use them to benchmark your
372 * Fixed the previous fix to `sonar'.
373 * Minor fix to `nerverot'.
374 Made sonar able to ping hosts on DEC OSF1.
375 * Eliminated a bogus "didn't get enough colors" warning
376 in some of the hacks.
377 Changes since 3.27: * New logo for xscreensaver!
378 * New hacks, `starwars' and `stonerview'.
379 * Made the motion of the bouncing ball in `stairs' be a
381 * Made newly-added screenhacks be added to .xscreensaver
382 automatically: if there are hacks in the app-defaults
383 file that are not also in ~/.xscreensaver, they will
384 be added to the end of the list.
385 * Redid the `Screensaver Options' part of the control
386 panel; xscreensaver now lets you configure your DPMS
388 * Fixed some Makefile problems with non-GL builds.
389 * Fixed detection of MesaGL for version 3.3.
390 * Better workaround to Red Hat 7.0's broken gcc.
391 * Added Sparc Solaris kernel panic to `bsod'.
392 Changes since 3.26: * New hacks: `zoom' and `whirlwindwarp'.
393 * Fixed a free-memory-reference bug in `sonar'.
394 * Better error handling when there are no suitable GL
396 * Added diagnostic dialog when xscreensaver-demo is
397 unable to launch xscreensaver (e.g., when running as
399 * Fixed a bug that caused screenhack argument changes
400 to be ignored when xscreensaver-demo was running as
401 root (if "root" and "nobody" have different home
403 * Made the programs default to ":0" if $DISPLAY is unset.
404 * Made the `-verbose' output include information about
405 which server extensions were supported at compile time.
406 * Worked around Red Hat 7.0's broken gcc 2.96.
407 * Updated default delays on the GL hacks to look better
408 on machines with super-fast 3D hardware.
409 * Install `screensaver-properties-capplet' to work around
410 the usual egregious GNOME lossage.
411 Changes since 3.25: * Added "enabled" checkboxes in the list of hacks in
412 xscreensaver-demo (Gtk version only.)
413 * New hacks `hyperball', `xrayswarm', and `gflux'.
414 * New versions of `nerverot', `galaxy', and `hypercube'.
415 * Small fixes to `phosphor', `shadebobs', `xflame',
417 * Added external helper program `xscreensaver-gl-helper'
418 to figure out which X visual to use for OpenGL
420 * Configure updates for XFree86 4.0, and for BSD.
421 * Made it be more tolerant of bogus /etc/group files.
422 * When installing the PAM config file, first try to just
423 copy an existing "xdm" or "login" config file, so that
424 xscreensaver does authentication in the same way as the
426 Changes since 3.24: * New hack, `nerverot'.
427 * Added BSD kernel panic to `bsod'.
428 * New version of `shadebobs'.
429 * New version of `petri'.
430 * Updated `webcollage' to handle recent Altavista URL
431 format changes; made it search the AP photo gallery.
432 * Revamped command-line options of `sonar' and made it
433 properly handle subnets.
434 * The `bubbles' hack can now trickle up or down the
436 * The `xsublim' hack can now read its text from programs.
437 * Support for GLE version 3 in `extrusion'.
438 * Fixed compilation problems in `maze'.
439 * Fixed a rare crash in `flow'.
440 * Fixes for minor installation problems.
441 Changes since 3.23: * Added `-ignorant' option to `maze' hack.
442 * Updates to `critical', `bsod', `xflame', and `flow'.
443 * Added support for Kerberos 5 (via its Kerberos 4
444 compatibility layer.)
445 * Fixed a bad leak in `xteevee'.
446 * Updated `webcollage' to handle recent Altavista URL
448 * Removed xscreensaver-demo's `Ok' and `Cancel' buttons,
449 since they were confusing people: all changes are now
451 * Made xscreensaver-demo install itself into the Gnome
453 Changes since 3.22: * Fixed some misplaced text fields in the Motif version
454 of xscreensaver-demo; fixed a crash in the Gtk version
455 that would happen if the programs list was empty.
456 * Fixed a recently-introduced bug in `pulsar'.
457 * Made `sierpinski3d' use solid tetrahedrons instead of
459 * Added `-trace' option to `xmatrix'.
460 * Added new hacks `xteevee' and `xspirograph'.
461 Changes since 3.21: * Fixed some bugs in xscreensaver-demo.
462 * Rewrote the Motif version of xscreensaver-demo to
463 match the new Gtk version.
464 * The Athena toolkit is no longer supported.
465 Changes since 3.20: * Tweaked the xscreensaver-demo UI (Gtk only.)
466 * Fixed a few visual selection bugs. I think the proper
467 GL visual should be used with nVidia systems now.
468 * Made the Makefiles obey $install_prefix.
469 * Made the `xscreensaver.spec' file able to generate both
470 GL and non-GL packages simultaneously.
471 Changes since 3.19: * Added new hacks `ripples' and `sierpinski3d'.
472 * Made `xscreensaver-command -exit' be silent when no
473 screen saver was running (instead of complaining.)
474 * Made `webcollage' and `vidwhacker' use `xloadimage'
475 when available (in addition to `xli' and `xv'.)
476 * Improved memory usage in `petri' and gave it a hard
477 cap on how much memory it can allocate.
478 * Added `-watch' option to `xscreensaver-command'.
479 * Made `xscreensaver-demo' come up with the
480 most-recently-run hack selected by default.
481 * Rewrote the Gtk version of `xscreensaver-demo'.
482 It's a lot easier to use now.
483 * Extended the format of the programs list in the
484 .xscreensaver file, for the benefit of the new
485 capabilities of `xscreensaver-demo'.
486 NOTE: you might want to delete your ~/.xscreensaver
487 file and allow it to be re-created! The old one
488 should still work, but xscreensaver-demo won't be as
490 Changes since 3.18: * Fixed gcc dependencies in `bumps' and `ccurve'.
491 * New hack, `extrusion'.
492 * Some of the web sites that `webcollage' was using as
493 its sources changed formats; tweaked it to understand
495 * Added typeahead in the password dialog: if the screen
496 is locked, and you unlock it by typing a character,
497 that key will be automatically inserted in the
498 password dialog (unless it is Return, Enter, Space,
499 or a non-printing key like Shift.)
500 * Made `xmatrix' take a `-small' option, since some
501 folks with tiny screens prefer a smaller font.
502 Changes since 3.17: * New versions of `shadebobs', `lmorph', and `distort'.
503 * Added `ccurve', `blaster', and `bumps' hacks.
504 * Replaced `forest' hack with a rewritten version.
505 * Worked around a Xinerama server bug.
506 * Fixed a bug I introduced in 3.10 that caused some
507 hacks to print out superfluous warnings about not
508 having gotten enough colors.
509 * Made `sproingies' obey the `-delay' option.
510 * Fixed a portability bug in `shadebobs'.
511 * Made `webcollage' and `vidwhacker' use `xli' in
512 preference to `xv', if it is available.
513 * Added a new source of images to `webcollage'.
514 * If running under KDE, xscreensaver will add itself to
515 KDE's list of screensavers (via xscreensaver.kss.)
516 * Improved detection of GL libraries.
517 * Made the password dialog include the date and time.
518 Changes since 3.16: * New version of `webcollage' -- deals better with
519 corrupted images, and can use an http proxy.
520 * New hack, `xsublim' (run it in the background,
521 rather than adding it to the programs list.)
522 * The xscreensaver daemon was leaking a file descriptor
523 each time you edited your .xscreensaver file. Fixed.
524 Changes since 3.15: * New version of `shadebobs'.
525 * Improved image selection in `webcollage', and sped it
527 * Made configure find the right version of perl.
528 * Rewrote the CGI part of `webcollage'.
529 * `make clean' was deleting some things it shouldn't.
530 * Fixed a typo in the default programs list.
531 Changes since 3.14: * Added `webcollage' and `shadebobs' hacks.
532 * Added a `-stdout' arg to `vidwhacker' so that it can
533 be used in a pipeline.
534 * Made `petri' use less memory.
535 Changes since 3.13: * Various improvements to the Gtk port.
536 * Turned off PAM by default on Solaris, since PAM seems
537 generally to be misconfigured out-of-the-box.
538 * Made the `--without-gtk' configure option work.
539 * Made configure check the Gtk version number, since it
541 * Fixed a bug in the code that attempted to prevent
542 changes of screen resolution while the screen is
544 * Fixed a race condition in `xscreensaver-demo' that
545 could cause an X error at startup.
546 * Added `-transparent' option to `deluxe'.
547 * Added `petri' hack.
548 Changes since 3.12: * Ported `xscreensaver-demo' to Gtk.
549 * Made it possible to build Motif, Gtk, and Athena
550 versions of `xscreensaver-demo' in the same directory
551 without reconfiguring.
552 * Made `xscreensaver-demo' chase symlinks before writing
553 the .xscreensaver file, so that if .xscreensaver is
554 itself a symlink, the underlying file will be replaced
556 * Some Makefile and configure tweaks for Solaris and
558 * Made it possible to set the fire color in `xflame'.
559 * Made transparency work in TrueColor (for `goop' and
561 * Fixed a multi-head bug introduced by the virtual
563 Changes since 3.11: * Made it so that you can't scroll the screen while the
564 lock dialog is up (with XFree86 virtual viewports.)
565 * Fixed a bug in `flag' that caused bob's chin to get cut
566 off after a few iterations.
567 Changes since 3.10: * Made `xjack' be black-on-white-ish, so that it looks
568 less like a computer screen and more like the
569 typewritten paper it's supposed to be.
570 * New version of `pulsar'.
571 * Fixed Solaris compilation problem in `phosphor'.
572 * Made xscreensaver notice XFree86's virtual root window
573 hack, so that if the X server's root window is larger
574 than the monitor's displayable resolution, the screen
575 saver will limit itself to the area that actually
576 appears on the screen.
577 * Made the xscreensaver daemon do a better job of
578 picking the visual class that should be used for GL
579 programs. Less user intervention should be needed
580 now: you can use the logical visual name `GL' instead
581 of having to figure out by hand which one to use.
582 * Oops, the visual was defaulting to "best" instead of
583 "default", because the .xscreensaver file was not being
584 loaded quite early enough.
585 * Made configure figure out how to build icmp ping
586 support into the `sonar' hack automatically.
587 * Made warnings about not being able to read shadow
588 passwords not be printed if compiled with PAM support.
589 * Improved PAM startup diagnostics.
590 * Worked around the Solaris PAM bug that was causing
591 crashes there, so now PAM is turned on by default.
592 * Made configure detect the number of arguments that
593 pam_strerror() takes, since on Linux, this apparently
594 changed between 2.0 and 2.2, sigh.
595 * Made the /proc/interrupts kludge look for "PS/2 Mouse"
596 as well as "keyboard".
597 * Made xscreensaver notice when there has been a sudden
598 large jump in wall-clock time, and if so, lock right
599 away, instead of waiting for "lockTimeout" to expire
600 first. (Laptops need this for safer recovery from
602 * Added `-throttle' option to `xscreensaver-command'.
603 Changes since 3.09: * Added `phosphor', `xmatrix', and `pulsar' hacks.
604 * Fixed a bug in the color allocator that sometimes
605 caused `starfish' to fall back to monochrome.
606 * Reduced the amount of code that runs before root
607 privileges are disavowed: "normal" and "shadow"
608 passwords now do some initialization as root, but the
609 PAM and Kerberos authorization schemes will be
610 initialized while running as "nobody". Supposedly
611 this closes a potential security hole when using
613 * Added some more sanity checking to configure.
614 Changes since 3.08: * Added `compass', `squiral', `xflame', `wander',
615 `spotlight', and `critical' hacks.
616 * Added some new modes to `decayscreen'.
617 * Made `deluxe' work in monochrome.
618 * Generalized usage of the Double-Buffer server extension
619 in several hacks (`compass', `deluxe', `interference',
620 `kumppa', and `moire2'.)
621 * Fixed another visual-depth problem in `rd-bomb'.
622 * The screen saver will now defer blanking if neither
623 the keyboard nor the mouse could be grabbed. Instead,
624 it will just try again in a few minutes. This fixes
625 a bad interaction between xscreensaver and programs
626 like VMware that hold the mouse and keyboard grabbed
628 * Added a new erase mode (expanding spiral.)
629 Changes since 3.07: * Fixed some bugs in my port of `t3d'.
630 * Added `penetrate' and `deluxe' hacks.
631 * When linking against Motif 2.x, also link against XPM.
632 * Added support for using /proc/interrupts for idle
633 detection on Linux. Now xscreensaver shouldn't kick
634 in when the user is active on a non-X virtual console.
635 * Upgraded to autoconf 2.13.
636 Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
637 in properly; check for _Xsetlocale in -lXintl.)
638 * Portability fixes for sonar.c.
639 * Fixed a compilation problem when you have GL but don't
641 * Made configure notice when MesaGL requires -lpthread.
642 * Made `flame' ignore SIGFPE (not sure if this is the
643 right fix; it seems only to be needed on FreeBSD.)
644 * Kludged `rd-bomb' work on visuals that are of depth 24
645 but that *do not* support pixmaps of depth 32.
646 * Fixed `halo' to work properly in TrueColor.
647 * Changed `xscreensaver.spec' to install the hacks in
648 /usr/X11R6/lib/xscreensaver/ by default, since that's
649 where recent Red Hat distributions put them.
651 * Updated versions of `crystal', `hopalong', and `flow'
653 * Imported `demon' and `loop' modes from xlockmore.
654 Changes since 3.05: * Oops, the "default-n" visual descriptor was broken;
655 it was always installing a colormap if the
656 `installColormap' preference was set, meaning that
657 `xearth', `xv' and friends were using the wrong
658 colors on 8-bit systems.
659 * Turned off HAVE_PING in `sonar', since it compiles
660 on some Linux systems, but not others of similar
662 Changes since 3.04: * Fixed an off-by-1 in `distort'.
663 * Added `sonar' hack.
664 * New version of `glplanet' (with stars.)
665 * Made all hacks exit when you type `q' or `ESC' at them,
666 and made them obey the WM_DELETE_WINDOW ClientMessage.
667 * Fixed a nonfatal buffer overrun in lament (note:
668 lament still doesn't work with MesaGL 3.0: it dies in
669 lambda_textured_triangle1(), which is Mesa's bug, not
671 Changes since 3.03: * Added an `xscreensaver.spec' file, to make it easier
672 for other folks to generate RPMs.
673 * Made the password code work on HPUX in the situation
674 where: ``enhanced security'' is available; but not
675 used; but the user typed a password more than 8
676 characters long anyway. FTSOHPUX.
677 Changes since 3.02: * Made locking work when passwd aging is enabled.
678 * Added support for PAM (Pluggable Authentication
679 Modules.) It is still turned off by default, though,
680 since it doesn't seem to work on Solaris 2.6, and has
681 been behaving erratically on Red Hat 5.1.
682 * Made each possible authentication method be tried in
683 turn until one succeeds; this means that Kerberos is
684 being used, we will first check Kerberos, and if that
685 fails, will then consult the local password file.
687 * Save and restore the bits under the passwd dialog,
688 to avoid leaving a black rectangle behind when
689 unlocking is cancelled.
690 Changes since 3.01: * Not everyone has sys/select.h, sigh...
691 Changes since 3.00: * Some fixes to `reflect'.
693 * Made it log unsuccessful attempts to unlock the screen
695 * Fixed a bug where `xscreensaver-demo' could be seeing
696 a different programs list than `xscreensaver' did.
697 Changes since 2.34: * The xscreensaver daemon no longer links against Motif
698 or Athena: demo-mode and the preferences panel are no
699 longer built in to the daemon, but are now handled by
700 an external program, `xscreensaver-demo'.
701 (I decided that this, along with the recent addition
702 of the `.xscreensaver' config file, justified bumping
703 the version number to 3.00, since this is a fairly
704 major architectural change.)
705 * Lines in the `*programs' resource may now begin with
706 the character "-", meaning "don't run this hack."
707 In this way, it's possible to disable a hack without
708 throwing away the information about it (making it
709 easier to change your mind later.) Eventually the
710 preferences/demo mode GUI should represent this as a
711 checkbox or something.
712 * Fixed a short race condition where it was possible for
713 xscreensaver to die with a BadWindow error if it was
714 blanking the screen just as another window was being
716 * Made it possible to disable specific modes in `bsod'.
717 Changes since 2.33: * Fixed a bug that was making `pipes' generate way too
718 many valves. Made the viewpoint in `pipes' be selected
719 randomly instead of always being -10 degrees.
720 * Fixed a bug in the XSHM code, in the case where the
721 server supports the XSHM extension but is not the same
722 machine as the client.
723 * Made `rd-bomb' default to taking up the whole screen.
724 * Made it not try to do fading/unfading if no PseudoColor
726 * Initial attempt at supporting VT-locking (doesn't work
728 * Eliminated the `captureStdout' resource; now
729 `captureStderr' controls both streams.
730 * Added `-capture-stderr' and `-no-capture-stderr'
731 command-line arguments.
732 * Added `glplanet' hack.
733 * When a hack is selected with `xscreensaver-command
734 -select', that hack will be used until further notice
735 (until the saver turns off, or another activation
737 Changes since 2.32: * Made `xscreensaver-command' print error messages:
738 the xscreensaver daemon now responds to ClientMessage
739 events by writing a response message on a window
740 property, instead of just writing to its stderr.
741 * Made the ~/.xscreensaver file be automatically reloaded
742 when the file date changes.
743 * The password dialog and splash screen no longer depend
744 on Motif or Athena. This should clear up a number of
745 focus problems, and is the first step on the path
746 toward moving all of the Motif/Athena/whatever code
747 out of the xscreensaver daemon, and into external
749 * Don't complain about LessTif 0.86 any more, since the
750 new password dialog makes that problem go away.
751 * Configure tweaks for Irix 6.5, SunOS 5.something.
752 * New `-reflect' option to `distort'.
753 Changes since 2.31: * Added reading and writing of a ~/.xscreensaver file,
754 so that the Preferences panel can save its settings.
755 * New version of `rubik'.
756 * Added `-select N' argument to `xscreensaver-command'.
757 * Oops, left out some of the `bubbles3d' files...
758 Changes since 2.30: * The cursor was invisible in the password dialog. Fixed.
759 * Made configure warn against MesaGL 2.6.
760 * Fixed X error at startup when using non-default visual.
761 * New version of `crystal', `ant', and `atlantis' from
763 * New hack, `bubble3d'.
764 * Added some new modes to `bsod'.
765 Changes since 2.29: * Changed the order in which -lSM and -lICE are linked
766 to be after Motif instead of before (Lesstif on Irix
768 Changes since 2.28: * Work around a bash bug in configure.
769 * Tweaked HPUX paths again. FTSOHPUX.
770 * Made configure recommend against LessTif 0.86, due
771 to a bug in that version that causes a security hole
772 in the screen locking code. LessTif 0.87 will fix it.
773 * Made all of the `--with' options to `configure' accept
774 a directory option as well (so that --with-motif=/FOO
775 will add -I/FOO/include -L/FOO/lib). I believe this is
776 the Configure Party Line of how do to such things.
777 * Fixed a bug where the mouse was left un-grabbed
778 after the first time the graphics hack was changed
779 (simplified all of the mouse-grabbing logic.)
780 * Maybe possibly perhaps made `vidwhacker' really not
781 leave stray xv windows around. This time for sure.
782 * Added a new erase mode (random dots fizzling out.)
783 * Added `-prefs' argument to `xscreensaver-command',
784 that brings up the Preferences dialog directly (it
785 seems that nobody ever noticed the `Preferences' button
786 on the Demo Mode dialog, maybe this will help.)
787 * Added a splash screen. Turn it off with *splash:false.
788 Changes since 2.27: * Better macsbug text in `bsod'.
789 * New version of `distort' with many new modes.
790 * Plugged a leak in `coral'.
791 * Tweaked configure for HPUX.
792 * Removed some compiler warnings.
793 * More consistent usage of stderr versus stdout.
794 * More diagnostics should an X error occur.
795 * Fixed a possible crash in SGI-specific unfading code.
796 Changes since 2.26: * Improved version of `distort'.
797 * Made `lament' compile against OpenGL 1.0 (though it
798 still requires 1.1 to work properly.)
799 * Updated my email address and home page.
800 Changes since 2.24: * Improved motion in `rd-bomb'.
801 * Added XSHM (shared memory extension) support to the
802 `distort', `interference', `moire', `rd-bomb', and
803 `swirl' hacks, which speeds them up a bit.
804 * Added `lament' hack.
805 Changes since 2.23: * Tweaked the order of the -L options again.
806 * Cleaned up configure's `--help' message.
807 * Added `kumppa' hack.
808 * Smarter maze-solving algorithm in `maze'.
809 * Took `xlyap' out of the default list of hacks, since
810 it's just incredibly buggy (and slow.) Maybe someday
811 someone will fix it...
812 * Added `distort' hack, but didn't add it to the default
813 list (yet) because it's still too slow.
814 * Made the Athena demo dialog look more like the Motif
815 version; it has a text-entry field now, too.
816 * Made the Athena password dialog echo asterisks, like
817 Motif does, instead of using a flyspeck font.
818 * Some random configure tweaks.
819 * Added a `timestamp' resource that makes the `-verbose'
820 messages include the time at which they were printed.
821 Changes since 2.22: * The fix for SGI's ``scheme'' nonsense broke things, and
822 let the user's "*background" resource show through.
823 Fixed it in a different way.
824 Changes since 2.21: * Added support for the DPMS server extension (Display
825 Power Management System.)
826 * Made configure advertize the `--enable-subdir' option a
827 little more, since that seemed to cause some people
828 stress. Also, made that directory be built into the
829 xscreensaver executable, as a hardcoded prefix to
830 $PATH. (Might help, shouldn't hurt.)
831 * Made configure prefer the two-arg gettimeofday to the
832 one-arg version, since AIX doesn't have any prototypes.
833 * Made it work with Xaw3d (the 3D Athena library.)
834 * Made `make install' create directories as necessary.
835 * New version of lmorph from Sverre.
836 * Added `crystal' and `discreet' hacks from xlockmore.
837 * Added a new mode to `bsod'.
838 Changes since 2.20: * Made `xscreensaver-command -time' use different words.
839 (It now describes the two states as "screen blanked
840 since..." and "screen non-blanked since..." instead of
841 "active since..." and "inactive since..." which a lot
842 of people interpreted as meaning the opposite of what
844 * Improved some error messages, in the hopes of making
845 the distinction between the xscreensaver and
846 xscreensaver-command programs more obvious.
847 * Rewrote (and reorganized) parts of the xscreensaver and
848 xscreensaver-command manual pages.
849 * Renamed xscreensaver's `-lock' command-line option to
850 be `-lock-mode', to avoid confusion with the `-lock'
851 option to xscreensaver-command, which does a totally
853 * Removed xscreensaver's `-demo' command-line option for
854 a similar reason; use `xscreensaver-command -demo'
856 * Disabled SGI's ``scheme'' nonsense in a better way than
857 fully-qualifying the background colors in every single
859 * Fixed some other minor cosmetic problems when *sgiMode
861 * Fixed an X error in `bsod -root' (how ironic...)
862 Changes since 2.19: * Fixed a bug that caused the mouse to sometimes not be
863 grabbed properly (meaning the window manager menu could
864 pop up over the demo-mode display.)
865 * Fixed a bug that made the stderr output sometimes get
867 * Fixed a bug that made the demo-mode scrollbar move too
869 * Protected against a possible buffer overflow.
870 * Made `vidwhacker' not leave stray xv windows around.
871 * New version of `ant' so that Bagley doesn't calve.
872 * Make configure on AIX get XShm from the right library.
873 Changes since 2.18: * One file was missing from the tar file. Fixed.
874 Changes since 2.17: * Oops, atlantis wasn't being built by default. Fixed.
875 * Added `epicycle' hack.
876 * Added `interference' hack.
877 * Added `truchet' hack.
879 * Added some new modes to `vidwhacker'.
880 Changes since 2.16: * Added a -window-id argument to most hacks, so that they
881 can draw on arbitrary externally-provided windows.
882 * Synched with xlockmore 4.11a01.
884 * Added `atlantis' GL hack.
885 * Renamed `puzzle' hack to `jigsaw', since xlock already
886 had a different mode called `puzzle'.
887 * Made it self-configure properly when Motif 2.1.0 is
888 being used (requires -lXp now, sigh...)
889 Changes since 2.15: * Made `flag' able to do XPM images.
890 * New look for the xscreensaver logo (`xroger').
891 * Fixed compilation error on Suns with adjunct passwords.
892 * Got multi-architecture builds working again.
893 * Some configure tweaks for building on HPUX and Solaris.
894 * Fixed bug in decayscreen.
895 * Fixed typo in passwd.c.
896 * Made `cynosure' not die when colormap is full.
897 Changes since 2.14: * Added `cynosure' hack.
898 * Added `moire2' hack.
899 * Tweaked `erase.c' some more.
900 * Made unfading a bit smoother.
901 * Added `vidwhacker' hack (not installed by default.)
902 * Added `stairs' hack.
903 * Split `escher' into `cage' and `moebius', as per
905 * Changed subprocess handling to use sigaction() instead
906 of signal() if it's available (this is necessary for
907 SCO but should work fine on other systems too.)
908 * Various other tweaks.
909 Changes since 2.13: * Better fix for the Motif drag-and-die lossage.
910 * Put in some kludges to work around a LessTif bug.
911 * XScreenSaver is known to work with LessTif 0.82 now.
912 * Made fading work on high-end SGI video hardware.
913 * Fixed another SGI-specific bug in screen grabbing;
914 will the madness never cease?
915 * Fixed another crash in `xlyap'.
916 Changes since 2.12: * Made `decayscreen' do directions other than down.
918 * Fixed a crash in `xlyap'.
919 * Added CDE info to the man page, removed `cde.txt'.
920 * Configure tweaks for Zippy.
921 * Turned off the signal handling in `bubbles' because
922 it was sometimes failing to die.
923 * Added `hacks/xscreensaver-sgigl.c' to make it possible
924 to run SGI's ElectroPaint hack (/usr/demos/bin/ep)
925 with xscreensaver. Finally!
926 * Fixed a buffer overrun in the locking code that some
927 wily, malicious cracker must have slipped in.
928 * Disabled Motif drag-and-drool in the dialog box
929 buttons, since it's broken in some old versions of
931 Changes since 2.11: * Added `README.debugging'.
932 * Added `puzzle' hack.
933 * Added `xlyap' hack.
934 * Added `default-n' as a visual name, so that one can
935 have -install on by default, but turn it off for
936 certain poorly-behaved hacks (like xv.)
937 * Added support for grabbing frames of external video
938 (on SGI) to the screen-grabbing hacks (decayscreen,
939 slidescreen, slip, blitspin, and puzzle.)
940 * Improved look of tiles in `slidescreen'; fixed its
941 color allocation problem.
942 Changes since 2.10: * Tweaked `blitspin', added it to the default list.
943 * Added `lissie', `mountain', `triangle', `worm',
944 `rotor', and `ant' from xlockmore.
945 * Updated `sierpinski', `galaxy', and `lisa'.
946 * Thickened the lines in `braid' and `lmorph'.
947 * Updated VMS makefiles.
948 * Renamed `fract' to `vines'.
949 * Added `xjack' hack.
950 * Made a few more hacks use erase.c, and added a few
952 * Fixed compilation problem with Sun's version of OpenGL.
953 * Added ability to use sigaction() instead of signal()
954 to work around a SCO kernel bug.
955 Changes since 2.09: * Fixed colormap bugs in `rd-bomb'; sped up `coral'.
956 * Configure tweaks for *BSD.
957 Changes since 2.07: * New hacks `rd-bomb' and `coral'.
958 * New version of `maze' with some new algorithms.
959 * New colorized version of `rocks'.
960 * Fixed a bug in qix on 64-bit machines.
961 * Fixed a bug in the -time option.
962 * Fixed a bug in configure related to LessTif.
963 Changes since 2.06: * Minor header tweaks in windows.c and flag.c.
964 * Made multi-architecture ($VPATH) builds work properly.
965 * Merged new GL stuff from xlockmore (rubik, morph3d.)
966 * Fixed intermittent crashes in `imsmap' and `munch'.
967 * Added `fadeplot' hack from xlockmore.
968 Changes since 2.05: * Merged in VMS support from Patrick Moreau.
969 Changes since 2.04: * Fixed a MIT-SCREEN-SAVER-related crash, and tweaked
970 configure to detect the extra-random -Xss library.
971 Changes since 2.03: * HP configure tweaks. Detect and warn about LessTif.
972 * Fixed low-color behavior of `goop', `pyro', `starfish',
973 `greynetic', `flame', `halo', and `moire'.
974 Changes since 2.02: * Fixed flicker in `pipes'. Fixed 3d in `bouboule'.
975 * Added `munch' hack.
976 * Added basic dependencies to the Makefile.in files.
977 Changes since 2.01: * Fixes for compiling with the MIT saver extension.
978 * Made the yow/fortune program be a configure option.
979 * Various configure tweaks.
980 Changes since 2.00: * Added `goop' and `starfish' hacks.
981 * Added colomap cycling to `halo'.
982 * Made `attraction' use the new colormap allocator.
983 * Added better $PATH diagnostics.
984 * There was a bug in frand! Color selection should be
986 Changes since 1.34: * Converted to use `configure' instead of `imake'.
987 * ANSI C is now required.
988 * Added Kerberos locking support, from Nat Lanza.
