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 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

85 Changes since 4.10: * New hacks, `hypertorus', `cubestorm', `glknots',
86 `blocktube', and `glmatrix'.
87 * Updates to `cloudlife', `engine', `xmatrix', and
89 * Rewrote `glslideshow': it should work on somewhat
90 wimpier video cards now.
91 * Various portability tweaks.
92 Changes since 4.09: * New hacks, `cloudlife' and `klein'.
93 * Added Apple ][+, HPUX, and OS/390 sessions to BSOD.
94 * Added some Matrix Reloaded text to `xmatrix'.
95 * Updates to `webcollage', `eruption', `jigglypuff',
96 `metaballs', and `endgame'.
97 * Completely ignore the `memoryLimit' setting now,
98 since it was still causing people GL grief.
99 * Various minor fixes.
100 Changes since 4.08: * New hacks, `flyingtoasters', `bouncingcow',
101 `jigglypuff', and `glslideshow'.
102 * More models in `engine'.
103 * Rewrote `xscreensaver-getimage' to remove reliance on
104 external image loaders (xv, chbg, xloadimage, etc.)
105 and to reduce flicker when loading files.
106 * Made `gflux' and `flipscreen3d' be mouse-spinnable.
107 Changes since 4.07: * New hacks, `atunnels' and `piecewise'.
108 * Physics improvement in `fluidballs'.
109 * Various fixes for XDarwin systems (X11 on MacOS X.)
110 * Added -clock option to `barcode'.
111 * Minor fixes to `endgame', `flurry', `flipscreen3d',
113 Changes since 4.06: * New hacks, `flurry', `metaballs', `eruption',
114 `popsquares', and `barcode'.
115 * Minor updates to `maze' for high density mazes.

121 * Updated `sproingies' with smooth, unsegmented surfaces.
122 * Fixed Perl version-sensitivity in
123 `xscreensaver-getimage-file'.
124 * Fixed GTK2 scrolling bug in `xscreensaver-demo'.
125 Changes since 4.05: * New hack, `glblur' (disabled by default, since it
126 requires fast OpenGL texture support.)
127 * New hack, `halftone'.
128 * Updates to `endgame', `queens', `bumps', `glplanet',
129 `engine', and `circuit'.
130 * New version of `menger' that uses far fewer polygons.
131 * Fixed minor bug in `critical' that could cause some
132 bogus X servers to crash.
133 * Better labels in `molecule': the labels now appear to
134 be attached to the atoms, instead of floating in front
136 * Fixed bug that could rarely cause GL hacks to fail to
137 double-buffer (causing intermittent flickering.)
138 * Fixed a relative-URL-parsing bug in `webcollage'.
139 * Fixed a bug that (sometimes) caused the window manager
140 close box to kill `xscreensaver-demo' with a crash
141 instead of a graceful exit.
142 * Updated xscreensaver.pam to the Red Hat 7.3 way.
143 * More Gnome2-related configure crap.
144 * Updated to latest `config.guess' and `config.sub'.
145 * Fixed occasional core dump in `distort'.
146 * Added a Linux fsck failure and kernel panic to `bsod'.
147 * Added MacOS X kernel panic to `bsod'.
148 * Fixed a bug in `bsod' (all bsod bugs are ironic.)
149 * Fixed a bug that caused `xscreensaver-gl-helper' to
150 print a nonsense visual ID with some versions of
151 `printf': this could cause GL programs to display
152 incorrectly (e.g., flickery.)
153 Changes since 4.04: * More `configure' tweaks to try and get things working
154 on systems that both Gtk 1.x and 2.x installed.
155 * New hack, `endgame'.
156 * Minor updates to `gltext'.
157 Changes since 4.03: * Support for GTK 2.x / GNOME 2.x.
158 * The `configure' script will now use `pkg-config' if
159 you have it, in preference to `gtk-config', etc.
160 * New hacks, `lavalite', `queens', and `anemone'.
161 * Minor updates to `spheremonics', `gltext', `xmatrix'.
162 * You can use the mouse to manually spin most of the GL
163 hacks now (when they are displaying in a window.)
164 * Fixed a bug in `webcollage' (due to recent Alta Vista
165 url changes) that was causing it to try and load
166 incorrect image URLs.
167 * Made `xscreensaver-getimage' use gdk_pixbuf if it is
168 available: this means that those hacks that load images
169 will no longer rely on "xv", "xloadimage", etc. This
170 will close a race condition that could sometimes cause
171 your desktop background to be changed; and also makes
172 it possible for those programs to operate on image
173 files when running in windowed mode.
174 * `webcollage' can now be used in conjunction with
175 `driftnet' to display images snooped from your local
176 ethernet instead of obtained from search engines.
177 * Added man pages for all the hacks that didn't have
179 Changes since 4.02: * New hack, `spheremonics'.
180 * Minor updates to `webcollage', `cage', `moebius',
181 `morph3d', `boxed', `circuit', and `helix'.
182 * `pulsar' and `extrusion' can now load texture JPEGs.
183 * `rubik' now does non-square cubes.
184 * `fluidballs' now does various sizes of balls.
185 * `menger' and `sierpinski3d' now also show polygon
187 * `molecule' displays real subscripts in the formulae.
188 * GTK internationalization/localization support.
189 * Better detection of the various versions of libxml.
190 * Upgraded to autoconf 2.53 (from 2.13.)
191 Changes since 4.01: * Plugged a few minor leaks in `xscreensaver' and
193 * New hacks, `cubenetic' and `fluidballs'.
195 * Fixed sphere projection error in `glplanet'; installed
196 a better image of earth.
197 * Added Win2K and MacOS 1 crashes to `bsod'.
198 * Put back previous (better) version of `forest' that
199 was accidentially downgraded in the last release.
200 * New version of `bumps'.
201 * Made FPS computation in GL hacks more efficient: it
202 will influence the results less, thus resulting in
203 higher (but more accurate) reported frame rates.
204 Changes since 4.00: * New hacks: `twang', `glsnake', `boxed', `sballs',
206 * New hacks `apollonian', `euler2d', `juggle',
207 `polyominoes' and `thornbird', from xlockmore.
208 * Merged recent xlockmore changes into `ant', `braid',
209 `demon', `discrete', `drift', `fadeplot', `forest',
210 `grav', `hopalong', `ifs', `laser', `lightning',
211 `lisa', `lissie', `loop', `mountain', `penrose',
212 `rotor', `sierpinski', `slip', `sphere', `spiral',
213 `strange', and `vines'.
214 * Fixed the `gltext' bug that sometimes caused
215 horizontal lines to vanish again. This time for sure.
216 * Sped up `webcollage' by adding a C helper program to
217 replace the PPM pipeline. It also pastes images
218 semi-transparently now.
219 * Added support for the gdk_pixbuf library: if this lib
220 is available, then `blitspin', `xflame', and `flag'
221 can load GIF, JPEG, and PNG images in addition to XPM
223 * Fixed a rare race condition where the desktop-grabbing
224 hacks could sometimes leave the screen wedged, if the
225 user moved the mouse exactly when they were grabbing
226 the screen image (it would un-wedge the next time the
227 saver timed out or was activated.)
228 * Fixed incorrect colors in the screen-grabbing GL hacks
229 (`gflux' and `flipscreen3d'.)
230 * Made SIGHUP restart the daemon process (though using
231 `xscreensaver-command -restart' is still the preferred
233 * Tweaks to `xspirograph'.
234 * Minor configure and portability tweaks.
235 Changes since 3.34: * Redesigned `xscreensaver-demo' GUI: it now includes
236 small-preview and per-hack configuration dialogs.
237 * Added three new modes of operation: `One Screen Saver',
238 `Blank Screen', and `Don't Blank' (in addition to the
239 historical `Random Screen Saver').
240 * Configure now defaults to installing the hacks in
241 <prefix>/lib/xscreensaver/ instead of <prefix>/bin/.
242 (Most distros already did it this way.)
243 * New GL hacks, `menger', `engine', `flipscreen3d'.
244 * Made `sierpinski3d' be more colorful.
245 * New versions of `xmatrix' and `nerverot'.
246 * Fixed a bug in `starwars' that made the font be drawn
247 with thin lines in -root mode.
248 * Fixed a bad colormap bug in `crystal' that could make
249 *subsequent* hacks malfunction!
250 * Made `gflux' able to grab screen images (`-mode grab').
251 * Updated `webcollage' for recent search engine changes.
252 * Removed most command-line options to `xscreensaver':
253 just edit the ~/.xscreensaver file instead.
254 * Improved behavior on multi-screen and Xinerama systems:
255 the mouse now stays on the screen where the user left
256 it, and the password and splash dialogs always appear
257 on the screen that has the mouse.
258 * Made the splash dialog use more Gtk-like colors;
259 made it have only two buttons, "Settings" and "Help".
260 * Made `sonar' understand `.ssh/known_hosts2' format
261 files, and be better about stripping out illegal
263 Changes since 3.33: * Turned `memoryLimit' off by default, sigh. Apparently
264 some versions of the GL libraries (appear to) allocate
265 hundreds of megs for every GL program, so `memoryLimit'
266 was causing GL programs to malfunction or crash on
268 * Improved fading on TrueColor XFree86 4.1.x systems.
269 * New GL hack, `circuit'.
270 * Added `fuzz' mode to `decayscreen'.
271 * New version of `whirlygig'.
272 * Added links to `xplanet' and `sphereEversion'.
273 * Fixed rare race condition that could make `sonar' hang.
274 * Fixed potential crash in `speedmine'.
275 * Made `xscreensaver-demo' not crash when imageDirectory
276 was set to a non-existent directory.
277 * Made `xscreensaver-getimage-video' invoke XawTV's
278 `streamer' program better.
279 * Made `phosphor' and `starwars' deal with CR, LF,
280 or CRLF line endings.
281 * Changes for Cygwin compilation environments.
282 * Made `sonar' compile on systems that can't ping.
283 * Configure changes for HPUX 10.20.
284 * Made PAM code work on Red Had 4.2 systems.
285 * Made `xscreensaver-command -deactivate' work when the
286 saver is not active: what that does is reset the idle
287 timer, as if keyboard input had been detected. This
288 was added for the benefit of people writing DVD-playing
289 software: they can now prevent the screensaver from
290 kicking in by sending a -deactivate message once a
291 minute while the movie is playing and not paused.
292 * Various minor portability tweaks.
293 Changes since 3.32: * New hacks, `speedmine' and `whirlygig'.
294 * Sped up `pyro', made the explosions look a bit better.
295 * Added better stars to `glplanet' and `starwars'.
296 * Many internal changes to `webcollage'.
297 * Some new options to `attraction'.
298 * Minor fix to `noseguy' to avoid un-erased pixels.
299 * Rewrote the screen-eraser effects so that they complete
300 in the same amount of time regardless of how slow
301 your X server is (some of them were glacial on servers
303 * Fixed a potential free memory reference that could
304 sometimes cause a crash at startup.
305 * Possibly fixed a problem that could cause the daemon
306 to crash with an X error. I was never able to
307 reproduce this problem, but I think I might have
308 figured out what caused it.
309 * Worked around a problem that caused PAM authentication
310 to fail on some Red Hat 7.x systems.
311 * Added a `memoryLimit' parameter that controls the
312 amount of memory a graphics hack may allocate: if they
313 try to allocate more than this, malloc() will fail
314 (and they will exit or (safely) crash, rather than
315 hogging memory.) Default is 50M.
316 * Made `gnome-help-browser' be the default way to display
317 man pages in `xscreensaver-demo', if running on a
319 Changes since 3.31: * The image-manipulating hacks (`slidescreen', etc.) can
320 now operate on randomly chosen image files from disk,
321 or on frames captured from the system's video input,
322 instead of (or in addition to) manipulating images of
324 * Rewrote `vidwhacker' to use the new image-grabbing
326 * Made fading work on TrueColor XFree86 4.x systems.
327 * Fixed a subtle rendering bug in `atlantis' (the fish
329 * Made `atlantis' have a texture simulating light
330 reflections from the surface of the ocean.
331 * Fixed up label placement in `molecule'.
332 * Better color bars in `xteevee'.
333 * Made `install-strip' not try to strip scripts.
334 Changes since 3.30: * Put in more sensible defaults for DPMS, and updated
335 the documentation to reflect the fact that all your
336 DPMS settings are now belong to xscreensaver.
337 * Fixed the `xscreensaver.spec' file so that `--force'
339 * New versions of `rotzoomer' and `nerverot'.
340 * Fixed an OSF/1 compilation problem in `molecule'.
341 Changes since 3.29: * New hacks, `molecule', `dangerball', and `rotzoomer'.
342 * New version of `gflux'.
343 * Made `gltext' able to display the current time.
344 * Fixed a floating-point-precision problem in `gltext'
345 that sometimes caused horizontal lines to vanish.
346 * Removed the `-window-id' option from the hacks:
347 it never worked right, and was unnecessary.
348 * Made the `starwars' hack use thicker lines, antialias
349 the text, and fade out at the far edge instead of just
351 * Fixed an SHM segment leak in `moire'.
352 Changes since 3.28: * Better rendering of the new logo.
353 * New hack, `gltext'.
354 * Added `-planetary' option to `gears', to draw a
355 different kind of gear system.
356 * Made motion and rotation be smoother in `gears',
357 `glplanet', `moebius', `rubik', and `sierpinski3d'.
358 * Improved coloration in `sierpinski3d'.
359 * Made the GL hacks react to window size changes.
360 * Made most of the GL hacks take a -fps option (like
361 `pulsar' did), so you can use them to benchmark your
363 * Fixed the previous fix to `sonar'.
364 * Minor fix to `nerverot'.
365 Made sonar able to ping hosts on DEC OSF1.
366 * Eliminated a bogus "didn't get enough colors" warning
367 in some of the hacks.
368 Changes since 3.27: * New logo for xscreensaver!
369 * New hacks, `starwars' and `stonerview'.
370 * Made the motion of the bouncing ball in `stairs' be a
372 * Made newly-added screenhacks be added to .xscreensaver
373 automatically: if there are hacks in the app-defaults
374 file that are not also in ~/.xscreensaver, they will
375 be added to the end of the list.
376 * Redid the `Screensaver Options' part of the control
377 panel; xscreensaver now lets you configure your DPMS
379 * Fixed some Makefile problems with non-GL builds.
380 * Fixed detection of MesaGL for version 3.3.
381 * Better workaround to Red Hat 7.0's broken gcc.
382 * Added Sparc Solaris kernel panic to `bsod'.
383 Changes since 3.26: * New hacks: `zoom' and `whirlwindwarp'.
384 * Fixed a free-memory-reference bug in `sonar'.
385 * Better error handling when there are no suitable GL
387 * Added diagnostic dialog when xscreensaver-demo is
388 unable to launch xscreensaver (e.g., when running as
390 * Fixed a bug that caused screenhack argument changes
391 to be ignored when xscreensaver-demo was running as
392 root (if "root" and "nobody" have different home
394 * Made the programs default to ":0" if $DISPLAY is unset.
395 * Made the `-verbose' output include information about
396 which server extensions were supported at compile time.
397 * Worked around Red Hat 7.0's broken gcc 2.96.
398 * Updated default delays on the GL hacks to look better
399 on machines with super-fast 3D hardware.
400 * Install `screensaver-properties-capplet' to work around
401 the usual egregious GNOME lossage.
402 Changes since 3.25: * Added "enabled" checkboxes in the list of hacks in
403 xscreensaver-demo (Gtk version only.)
404 * New hacks `hyperball', `xrayswarm', and `gflux'.
405 * New versions of `nerverot', `galaxy', and `hypercube'.
406 * Small fixes to `phosphor', `shadebobs', `xflame',
408 * Added external helper program `xscreensaver-gl-helper'
409 to figure out which X visual to use for OpenGL
411 * Configure updates for XFree86 4.0, and for BSD.
412 * Made it be more tolerant of bogus /etc/group files.
413 * When installing the PAM config file, first try to just
414 copy an existing "xdm" or "login" config file, so that
415 xscreensaver does authentication in the same way as the
417 Changes since 3.24: * New hack, `nerverot'.
418 * Added BSD kernel panic to `bsod'.
419 * New version of `shadebobs'.
420 * New version of `petri'.
421 * Updated `webcollage' to handle recent Altavista URL
422 format changes; made it search the AP photo gallery.
423 * Revamped command-line options of `sonar' and made it
424 properly handle subnets.
425 * The `bubbles' hack can now trickle up or down the
427 * The `xsublim' hack can now read its text from programs.
428 * Support for GLE version 3 in `extrusion'.
429 * Fixed compilation problems in `maze'.
430 * Fixed a rare crash in `flow'.
431 * Fixes for minor installation problems.
432 Changes since 3.23: * Added `-ignorant' option to `maze' hack.
433 * Updates to `critical', `bsod', `xflame', and `flow'.
434 * Added support for Kerberos 5 (via its Kerberos 4
435 compatibility layer.)
436 * Fixed a bad leak in `xteevee'.
437 * Updated `webcollage' to handle recent Altavista URL
439 * Removed xscreensaver-demo's `Ok' and `Cancel' buttons,
440 since they were confusing people: all changes are now
442 * Made xscreensaver-demo install itself into the Gnome
444 Changes since 3.22: * Fixed some misplaced text fields in the Motif version
445 of xscreensaver-demo; fixed a crash in the Gtk version
446 that would happen if the programs list was empty.
447 * Fixed a recently-introduced bug in `pulsar'.
448 * Made `sierpinski3d' use solid tetrahedrons instead of
450 * Added `-trace' option to `xmatrix'.
451 * Added new hacks `xteevee' and `xspirograph'.
452 Changes since 3.21: * Fixed some bugs in xscreensaver-demo.
453 * Rewrote the Motif version of xscreensaver-demo to
454 match the new Gtk version.
455 * The Athena toolkit is no longer supported.
456 Changes since 3.20: * Tweaked the xscreensaver-demo UI (Gtk only.)
457 * Fixed a few visual selection bugs. I think the proper
458 GL visual should be used with nVidia systems now.
459 * Made the Makefiles obey $install_prefix.
460 * Made the `xscreensaver.spec' file able to generate both
461 GL and non-GL packages simultaneously.
462 Changes since 3.19: * Added new hacks `ripples' and `sierpinski3d'.
463 * Made `xscreensaver-command -exit' be silent when no
464 screen saver was running (instead of complaining.)
465 * Made `webcollage' and `vidwhacker' use `xloadimage'
466 when available (in addition to `xli' and `xv'.)
467 * Improved memory usage in `petri' and gave it a hard
468 cap on how much memory it can allocate.
469 * Added `-watch' option to `xscreensaver-command'.
470 * Made `xscreensaver-demo' come up with the
471 most-recently-run hack selected by default.
472 * Rewrote the Gtk version of `xscreensaver-demo'.
473 It's a lot easier to use now.
474 * Extended the format of the programs list in the
475 .xscreensaver file, for the benefit of the new
476 capabilities of `xscreensaver-demo'.
477 NOTE: you might want to delete your ~/.xscreensaver
478 file and allow it to be re-created! The old one
479 should still work, but xscreensaver-demo won't be as
481 Changes since 3.18: * Fixed gcc dependencies in `bumps' and `ccurve'.
482 * New hack, `extrusion'.
483 * Some of the web sites that `webcollage' was using as
484 its sources changed formats; tweaked it to understand
486 * Added typeahead in the password dialog: if the screen
487 is locked, and you unlock it by typing a character,
488 that key will be automatically inserted in the
489 password dialog (unless it is Return, Enter, Space,
490 or a non-printing key like Shift.)
491 * Made `xmatrix' take a `-small' option, since some
492 folks with tiny screens prefer a smaller font.
493 Changes since 3.17: * New versions of `shadebobs', `lmorph', and `distort'.
494 * Added `ccurve', `blaster', and `bumps' hacks.
495 * Replaced `forest' hack with a rewritten version.
496 * Worked around a Xinerama server bug.
497 * Fixed a bug I introduced in 3.10 that caused some
498 hacks to print out superfluous warnings about not
499 having gotten enough colors.
500 * Made `sproingies' obey the `-delay' option.
501 * Fixed a portability bug in `shadebobs'.
502 * Made `webcollage' and `vidwhacker' use `xli' in
503 preference to `xv', if it is available.
504 * Added a new source of images to `webcollage'.
505 * If running under KDE, xscreensaver will add itself to
506 KDE's list of screensavers (via xscreensaver.kss.)
507 * Improved detection of GL libraries.
508 * Made the password dialog include the date and time.
509 Changes since 3.16: * New version of `webcollage' -- deals better with
510 corrupted images, and can use an http proxy.
511 * New hack, `xsublim' (run it in the background,
512 rather than adding it to the programs list.)
513 * The xscreensaver daemon was leaking a file descriptor
514 each time you edited your .xscreensaver file. Fixed.
515 Changes since 3.15: * New version of `shadebobs'.
516 * Improved image selection in `webcollage', and sped it
518 * Made configure find the right version of perl.
519 * Rewrote the CGI part of `webcollage'.
520 * `make clean' was deleting some things it shouldn't.
521 * Fixed a typo in the default programs list.
522 Changes since 3.14: * Added `webcollage' and `shadebobs' hacks.
523 * Added a `-stdout' arg to `vidwhacker' so that it can
524 be used in a pipeline.
525 * Made `petri' use less memory.
526 Changes since 3.13: * Various improvements to the Gtk port.
527 * Turned off PAM by default on Solaris, since PAM seems
528 generally to be misconfigured out-of-the-box.
529 * Made the `--without-gtk' configure option work.
530 * Made configure check the Gtk version number, since it
532 * Fixed a bug in the code that attempted to prevent
533 changes of screen resolution while the screen is
535 * Fixed a race condition in `xscreensaver-demo' that
536 could cause an X error at startup.
537 * Added `-transparent' option to `deluxe'.
538 * Added `petri' hack.
539 Changes since 3.12: * Ported `xscreensaver-demo' to Gtk.
540 * Made it possible to build Motif, Gtk, and Athena
541 versions of `xscreensaver-demo' in the same directory
542 without reconfiguring.
543 * Made `xscreensaver-demo' chase symlinks before writing
544 the .xscreensaver file, so that if .xscreensaver is
545 itself a symlink, the underlying file will be replaced
547 * Some Makefile and configure tweaks for Solaris and
549 * Made it possible to set the fire color in `xflame'.
550 * Made transparency work in TrueColor (for `goop' and
552 * Fixed a multi-head bug introduced by the virtual
554 Changes since 3.11: * Made it so that you can't scroll the screen while the
555 lock dialog is up (with XFree86 virtual viewports.)
556 * Fixed a bug in `flag' that caused bob's chin to get cut
557 off after a few iterations.
558 Changes since 3.10: * Made `xjack' be black-on-white-ish, so that it looks
559 less like a computer screen and more like the
560 typewritten paper it's supposed to be.
561 * New version of `pulsar'.
562 * Fixed Solaris compilation problem in `phosphor'.
563 * Made xscreensaver notice XFree86's virtual root window
564 hack, so that if the X server's root window is larger
565 than the monitor's displayable resolution, the screen
566 saver will limit itself to the area that actually
567 appears on the screen.
568 * Made the xscreensaver daemon do a better job of
569 picking the visual class that should be used for GL
570 programs. Less user intervention should be needed
571 now: you can use the logical visual name `GL' instead
572 of having to figure out by hand which one to use.
573 * Oops, the visual was defaulting to "best" instead of
574 "default", because the .xscreensaver file was not being
575 loaded quite early enough.
576 * Made configure figure out how to build icmp ping
577 support into the `sonar' hack automatically.
578 * Made warnings about not being able to read shadow
579 passwords not be printed if compiled with PAM support.
580 * Improved PAM startup diagnostics.
581 * Worked around the Solaris PAM bug that was causing
582 crashes there, so now PAM is turned on by default.
583 * Made configure detect the number of arguments that
584 pam_strerror() takes, since on Linux, this apparently
585 changed between 2.0 and 2.2, sigh.
586 * Made the /proc/interrupts kludge look for "PS/2 Mouse"
587 as well as "keyboard".
588 * Made xscreensaver notice when there has been a sudden
589 large jump in wall-clock time, and if so, lock right
590 away, instead of waiting for "lockTimeout" to expire
591 first. (Laptops need this for safer recovery from
593 * Added `-throttle' option to `xscreensaver-command'.
594 Changes since 3.09: * Added `phosphor', `xmatrix', and `pulsar' hacks.
595 * Fixed a bug in the color allocator that sometimes
596 caused `starfish' to fall back to monochrome.
597 * Reduced the amount of code that runs before root
598 privileges are disavowed: "normal" and "shadow"
599 passwords now do some initialization as root, but the
600 PAM and Kerberos authorization schemes will be
601 initialized while running as "nobody". Supposedly
602 this closes a potential security hole when using
604 * Added some more sanity checking to configure.
605 Changes since 3.08: * Added `compass', `squiral', `xflame', `wander',
606 `spotlight', and `critical' hacks.
607 * Added some new modes to `decayscreen'.
608 * Made `deluxe' work in monochrome.
609 * Generalized usage of the Double-Buffer server extension
610 in several hacks (`compass', `deluxe', `interference',
611 `kumppa', and `moire2'.)
612 * Fixed another visual-depth problem in `rd-bomb'.
613 * The screen saver will now defer blanking if neither
614 the keyboard nor the mouse could be grabbed. Instead,
615 it will just try again in a few minutes. This fixes
616 a bad interaction between xscreensaver and programs
617 like VMware that hold the mouse and keyboard grabbed
619 * Added a new erase mode (expanding spiral.)
620 Changes since 3.07: * Fixed some bugs in my port of `t3d'.
621 * Added `penetrate' and `deluxe' hacks.
622 * When linking against Motif 2.x, also link against XPM.
623 * Added support for using /proc/interrupts for idle
624 detection on Linux. Now xscreensaver shouldn't kick
625 in when the user is active on a non-X virtual console.
626 * Upgraded to autoconf 2.13.
627 Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
628 in properly; check for _Xsetlocale in -lXintl.)
629 * Portability fixes for sonar.c.
630 * Fixed a compilation problem when you have GL but don't
632 * Made configure notice when MesaGL requires -lpthread.
633 * Made `flame' ignore SIGFPE (not sure if this is the
634 right fix; it seems only to be needed on FreeBSD.)
635 * Kludged `rd-bomb' work on visuals that are of depth 24
636 but that *do not* support pixmaps of depth 32.
637 * Fixed `halo' to work properly in TrueColor.
638 * Changed `xscreensaver.spec' to install the hacks in
639 /usr/X11R6/lib/xscreensaver/ by default, since that's
640 where recent Red Hat distributions put them.
642 * Updated versions of `crystal', `hopalong', and `flow'
644 * Imported `demon' and `loop' modes from xlockmore.
645 Changes since 3.05: * Oops, the "default-n" visual descriptor was broken;
646 it was always installing a colormap if the
647 `installColormap' preference was set, meaning that
648 `xearth', `xv' and friends were using the wrong
649 colors on 8-bit systems.
650 * Turned off HAVE_PING in `sonar', since it compiles
651 on some Linux systems, but not others of similar
653 Changes since 3.04: * Fixed an off-by-1 in `distort'.
654 * Added `sonar' hack.
655 * New version of `glplanet' (with stars.)
656 * Made all hacks exit when you type `q' or `ESC' at them,
657 and made them obey the WM_DELETE_WINDOW ClientMessage.
658 * Fixed a nonfatal buffer overrun in lament (note:
659 lament still doesn't work with MesaGL 3.0: it dies in
660 lambda_textured_triangle1(), which is Mesa's bug, not
662 Changes since 3.03: * Added an `xscreensaver.spec' file, to make it easier
663 for other folks to generate RPMs.
664 * Made the password code work on HPUX in the situation
665 where: ``enhanced security'' is available; but not
666 used; but the user typed a password more than 8
667 characters long anyway. FTSOHPUX.
668 Changes since 3.02: * Made locking work when passwd aging is enabled.
669 * Added support for PAM (Pluggable Authentication
670 Modules.) It is still turned off by default, though,
671 since it doesn't seem to work on Solaris 2.6, and has
672 been behaving erratically on Red Hat 5.1.
673 * Made each possible authentication method be tried in
674 turn until one succeeds; this means that Kerberos is
675 being used, we will first check Kerberos, and if that
676 fails, will then consult the local password file.
678 * Save and restore the bits under the passwd dialog,
679 to avoid leaving a black rectangle behind when
680 unlocking is cancelled.
681 Changes since 3.01: * Not everyone has sys/select.h, sigh...
682 Changes since 3.00: * Some fixes to `reflect'.
684 * Made it log unsuccessful attempts to unlock the screen
686 * Fixed a bug where `xscreensaver-demo' could be seeing
687 a different programs list than `xscreensaver' did.
688 Changes since 2.34: * The xscreensaver daemon no longer links against Motif
689 or Athena: demo-mode and the preferences panel are no
690 longer built in to the daemon, but are now handled by
691 an external program, `xscreensaver-demo'.
692 (I decided that this, along with the recent addition
693 of the `.xscreensaver' config file, justified bumping
694 the version number to 3.00, since this is a fairly
695 major architectural change.)
696 * Lines in the `*programs' resource may now begin with
697 the character "-", meaning "don't run this hack."
698 In this way, it's possible to disable a hack without
699 throwing away the information about it (making it
700 easier to change your mind later.) Eventually the
701 preferences/demo mode GUI should represent this as a
702 checkbox or something.
703 * Fixed a short race condition where it was possible for
704 xscreensaver to die with a BadWindow error if it was
705 blanking the screen just as another window was being
707 * Made it possible to disable specific modes in `bsod'.
708 Changes since 2.33: * Fixed a bug that was making `pipes' generate way too
709 many valves. Made the viewpoint in `pipes' be selected
710 randomly instead of always being -10 degrees.
711 * Fixed a bug in the XSHM code, in the case where the
712 server supports the XSHM extension but is not the same
713 machine as the client.
714 * Made `rd-bomb' default to taking up the whole screen.
715 * Made it not try to do fading/unfading if no PseudoColor
717 * Initial attempt at supporting VT-locking (doesn't work
719 * Eliminated the `captureStdout' resource; now
720 `captureStderr' controls both streams.
721 * Added `-capture-stderr' and `-no-capture-stderr'
722 command-line arguments.
723 * Added `glplanet' hack.
724 * When a hack is selected with `xscreensaver-command
725 -select', that hack will be used until further notice
726 (until the saver turns off, or another activation
728 Changes since 2.32: * Made `xscreensaver-command' print error messages:
729 the xscreensaver daemon now responds to ClientMessage
730 events by writing a response message on a window
731 property, instead of just writing to its stderr.
732 * Made the ~/.xscreensaver file be automatically reloaded
733 when the file date changes.
734 * The password dialog and splash screen no longer depend
735 on Motif or Athena. This should clear up a number of
736 focus problems, and is the first step on the path
737 toward moving all of the Motif/Athena/whatever code
738 out of the xscreensaver daemon, and into external
740 * Don't complain about LessTif 0.86 any more, since the
741 new password dialog makes that problem go away.
742 * Configure tweaks for Irix 6.5, SunOS 5.something.
743 * New `-reflect' option to `distort'.
744 Changes since 2.31: * Added reading and writing of a ~/.xscreensaver file,
745 so that the Preferences panel can save its settings.
746 * New version of `rubik'.
747 * Added `-select N' argument to `xscreensaver-command'.
748 * Oops, left out some of the `bubbles3d' files...
749 Changes since 2.30: * The cursor was invisible in the password dialog. Fixed.
750 * Made configure warn against MesaGL 2.6.
751 * Fixed X error at startup when using non-default visual.
752 * New version of `crystal', `ant', and `atlantis' from
754 * New hack, `bubble3d'.
755 * Added some new modes to `bsod'.
756 Changes since 2.29: * Changed the order in which -lSM and -lICE are linked
757 to be after Motif instead of before (Lesstif on Irix
759 Changes since 2.28: * Work around a bash bug in configure.
760 * Tweaked HPUX paths again. FTSOHPUX.
761 * Made configure recommend against LessTif 0.86, due
762 to a bug in that version that causes a security hole
763 in the screen locking code. LessTif 0.87 will fix it.
764 * Made all of the `--with' options to `configure' accept
765 a directory option as well (so that --with-motif=/FOO
766 will add -I/FOO/include -L/FOO/lib). I believe this is
767 the Configure Party Line of how do to such things.
768 * Fixed a bug where the mouse was left un-grabbed
769 after the first time the graphics hack was changed
770 (simplified all of the mouse-grabbing logic.)
771 * Maybe possibly perhaps made `vidwhacker' really not
772 leave stray xv windows around. This time for sure.
773 * Added a new erase mode (random dots fizzling out.)
774 * Added `-prefs' argument to `xscreensaver-command',
775 that brings up the Preferences dialog directly (it
776 seems that nobody ever noticed the `Preferences' button
777 on the Demo Mode dialog, maybe this will help.)
778 * Added a splash screen. Turn it off with *splash:false.
779 Changes since 2.27: * Better macsbug text in `bsod'.
780 * New version of `distort' with many new modes.
781 * Plugged a leak in `coral'.
782 * Tweaked configure for HPUX.
783 * Removed some compiler warnings.
784 * More consistent usage of stderr versus stdout.
785 * More diagnostics should an X error occur.
786 * Fixed a possible crash in SGI-specific unfading code.
787 Changes since 2.26: * Improved version of `distort'.
788 * Made `lament' compile against OpenGL 1.0 (though it
789 still requires 1.1 to work properly.)
790 * Updated my email address and home page.
791 Changes since 2.24: * Improved motion in `rd-bomb'.
792 * Added XSHM (shared memory extension) support to the
793 `distort', `interference', `moire', `rd-bomb', and
794 `swirl' hacks, which speeds them up a bit.
795 * Added `lament' hack.
796 Changes since 2.23: * Tweaked the order of the -L options again.
797 * Cleaned up configure's `--help' message.
798 * Added `kumppa' hack.
799 * Smarter maze-solving algorithm in `maze'.
800 * Took `xlyap' out of the default list of hacks, since
801 it's just incredibly buggy (and slow.) Maybe someday
802 someone will fix it...
803 * Added `distort' hack, but didn't add it to the default
804 list (yet) because it's still too slow.
805 * Made the Athena demo dialog look more like the Motif
806 version; it has a text-entry field now, too.
807 * Made the Athena password dialog echo asterisks, like
808 Motif does, instead of using a flyspeck font.
809 * Some random configure tweaks.
810 * Added a `timestamp' resource that makes the `-verbose'
811 messages include the time at which they were printed.
812 Changes since 2.22: * The fix for SGI's ``scheme'' nonsense broke things, and
813 let the user's "*background" resource show through.
814 Fixed it in a different way.
815 Changes since 2.21: * Added support for the DPMS server extension (Display
816 Power Management System.)
817 * Made configure advertize the `--enable-subdir' option a
818 little more, since that seemed to cause some people
819 stress. Also, made that directory be built into the
820 xscreensaver executable, as a hardcoded prefix to
821 $PATH. (Might help, shouldn't hurt.)
822 * Made configure prefer the two-arg gettimeofday to the
823 one-arg version, since AIX doesn't have any prototypes.
824 * Made it work with Xaw3d (the 3D Athena library.)
825 * Made `make install' create directories as necessary.
826 * New version of lmorph from Sverre.
827 * Added `crystal' and `discreet' hacks from xlockmore.
828 * Added a new mode to `bsod'.
829 Changes since 2.20: * Made `xscreensaver-command -time' use different words.
830 (It now describes the two states as "screen blanked
831 since..." and "screen non-blanked since..." instead of
832 "active since..." and "inactive since..." which a lot
833 of people interpreted as meaning the opposite of what
835 * Improved some error messages, in the hopes of making
836 the distinction between the xscreensaver and
837 xscreensaver-command programs more obvious.
838 * Rewrote (and reorganized) parts of the xscreensaver and
839 xscreensaver-command manual pages.
840 * Renamed xscreensaver's `-lock' command-line option to
841 be `-lock-mode', to avoid confusion with the `-lock'
842 option to xscreensaver-command, which does a totally
844 * Removed xscreensaver's `-demo' command-line option for
845 a similar reason; use `xscreensaver-command -demo'
847 * Disabled SGI's ``scheme'' nonsense in a better way than
848 fully-qualifying the background colors in every single
850 * Fixed some other minor cosmetic problems when *sgiMode
852 * Fixed an X error in `bsod -root' (how ironic...)
853 Changes since 2.19: * Fixed a bug that caused the mouse to sometimes not be
854 grabbed properly (meaning the window manager menu could
855 pop up over the demo-mode display.)
856 * Fixed a bug that made the stderr output sometimes get
858 * Fixed a bug that made the demo-mode scrollbar move too
860 * Protected against a possible buffer overflow.
861 * Made `vidwhacker' not leave stray xv windows around.
862 * New version of `ant' so that Bagley doesn't calve.
863 * Make configure on AIX get XShm from the right library.
864 Changes since 2.18: * One file was missing from the tar file. Fixed.
865 Changes since 2.17: * Oops, atlantis wasn't being built by default. Fixed.
866 * Added `epicycle' hack.
867 * Added `interference' hack.
868 * Added `truchet' hack.
870 * Added some new modes to `vidwhacker'.
871 Changes since 2.16: * Added a -window-id argument to most hacks, so that they
872 can draw on arbitrary externally-provided windows.
873 * Synched with xlockmore 4.11a01.
875 * Added `atlantis' GL hack.
876 * Renamed `puzzle' hack to `jigsaw', since xlock already
877 had a different mode called `puzzle'.
878 * Made it self-configure properly when Motif 2.1.0 is
879 being used (requires -lXp now, sigh...)
880 Changes since 2.15: * Made `flag' able to do XPM images.
881 * New look for the xscreensaver logo (`xroger').
882 * Fixed compilation error on Suns with adjunct passwords.
883 * Got multi-architecture builds working again.
884 * Some configure tweaks for building on HPUX and Solaris.
885 * Fixed bug in decayscreen.
886 * Fixed typo in passwd.c.
887 * Made `cynosure' not die when colormap is full.
888 Changes since 2.14: * Added `cynosure' hack.
889 * Added `moire2' hack.
890 * Tweaked `erase.c' some more.
891 * Made unfading a bit smoother.
892 * Added `vidwhacker' hack (not installed by default.)
893 * Added `stairs' hack.
894 * Split `escher' into `cage' and `moebius', as per
896 * Changed subprocess handling to use sigaction() instead
897 of signal() if it's available (this is necessary for
898 SCO but should work fine on other systems too.)
899 * Various other tweaks.
900 Changes since 2.13: * Better fix for the Motif drag-and-die lossage.
901 * Put in some kludges to work around a LessTif bug.
902 * XScreenSaver is known to work with LessTif 0.82 now.
903 * Made fading work on high-end SGI video hardware.
904 * Fixed another SGI-specific bug in screen grabbing;
905 will the madness never cease?
906 * Fixed another crash in `xlyap'.
907 Changes since 2.12: * Made `decayscreen' do directions other than down.
909 * Fixed a crash in `xlyap'.
910 * Added CDE info to the man page, removed `cde.txt'.
911 * Configure tweaks for Zippy.
912 * Turned off the signal handling in `bubbles' because
913 it was sometimes failing to die.
914 * Added `hacks/xscreensaver-sgigl.c' to make it possible
915 to run SGI's ElectroPaint hack (/usr/demos/bin/ep)
916 with xscreensaver. Finally!
917 * Fixed a buffer overrun in the locking code that some
918 wily, malicious cracker must have slipped in.
919 * Disabled Motif drag-and-drool in the dialog box
920 buttons, since it's broken in some old versions of
922 Changes since 2.11: * Added `README.debugging'.
923 * Added `puzzle' hack.
924 * Added `xlyap' hack.
925 * Added `default-n' as a visual name, so that one can
926 have -install on by default, but turn it off for
927 certain poorly-behaved hacks (like xv.)
928 * Added support for grabbing frames of external video
929 (on SGI) to the screen-grabbing hacks (decayscreen,
930 slidescreen, slip, blitspin, and puzzle.)
931 * Improved look of tiles in `slidescreen'; fixed its
932 color allocation problem.
933 Changes since 2.10: * Tweaked `blitspin', added it to the default list.
934 * Added `lissie', `mountain', `triangle', `worm',
935 `rotor', and `ant' from xlockmore.
936 * Updated `sierpinski', `galaxy', and `lisa'.
937 * Thickened the lines in `braid' and `lmorph'.
938 * Updated VMS makefiles.
939 * Renamed `fract' to `vines'.
940 * Added `xjack' hack.
941 * Made a few more hacks use erase.c, and added a few
943 * Fixed compilation problem with Sun's version of OpenGL.
944 * Added ability to use sigaction() instead of signal()
945 to work around a SCO kernel bug.
946 Changes since 2.09: * Fixed colormap bugs in `rd-bomb'; sped up `coral'.
947 * Configure tweaks for *BSD.
948 Changes since 2.07: * New hacks `rd-bomb' and `coral'.
949 * New version of `maze' with some new algorithms.
950 * New colorized version of `rocks'.
951 * Fixed a bug in qix on 64-bit machines.
952 * Fixed a bug in the -time option.
953 * Fixed a bug in configure related to LessTif.
954 Changes since 2.06: * Minor header tweaks in windows.c and flag.c.
955 * Made multi-architecture ($VPATH) builds work properly.
956 * Merged new GL stuff from xlockmore (rubik, morph3d.)
957 * Fixed intermittent crashes in `imsmap' and `munch'.
958 * Added `fadeplot' hack from xlockmore.
959 Changes since 2.05: * Merged in VMS support from Patrick Moreau.
960 Changes since 2.04: * Fixed a MIT-SCREEN-SAVER-related crash, and tweaked
961 configure to detect the extra-random -Xss library.
962 Changes since 2.03: * HP configure tweaks. Detect and warn about LessTif.
963 * Fixed low-color behavior of `goop', `pyro', `starfish',
964 `greynetic', `flame', `halo', and `moire'.
965 Changes since 2.02: * Fixed flicker in `pipes'. Fixed 3d in `bouboule'.
966 * Added `munch' hack.
967 * Added basic dependencies to the Makefile.in files.
968 Changes since 2.01: * Fixes for compiling with the MIT saver extension.
969 * Made the yow/fortune program be a configure option.
970 * Various configure tweaks.
971 Changes since 2.00: * Added `goop' and `starfish' hacks.
972 * Added colomap cycling to `halo'.
973 * Made `attraction' use the new colormap allocator.
974 * Added better $PATH diagnostics.
975 * There was a bug in frand! Color selection should be
977 Changes since 1.34: * Converted to use `configure' instead of `imake'.
978 * ANSI C is now required.
979 * Added Kerberos locking support, from Nat Lanza.
980 * Made the stderr text use overlay planes, if possible.
981 * Reworked the xlockmore compatibility stuff again.
982 * Added `gears', `superquadrics', `escher', `pipes',
983 and `sproingies' hacks (depend on OpenGL.)
984 Changes since 1.33: * Fixed some bugs, made fading be a little smoother.
985 Changes since 1.32: * Made it work with multi-headed displays.
986 * Generalized sub-process management (Unix sucks!)
987 * Added interactive mouse frobbing to Julia.
