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.)
21 The most important hint is probably this:
23 ./configure --with-motif=/opt/Motif --with-xpm=/usr/local
25 To build on VMS, see README.VMS.
27 If you think you've found a bug, please let me know! No bug report is too
28 small. But first, please read the enclosed `README.debugging' file to find
29 out what kind of information would be most helpful to include in your bug
34 You can try out xscreensaver like so:
39 The XScreenSaver suite of applications uses a client-server model:
40 The `xscreensaver' program is a daemon that runs in the background;
41 it is controlled by the foreground `xscreensaver-demo' program.
43 xscreensaver has an extensive manual -- please read it!
47 The xscreensaver daemon waits until the keyboard and mouse have been idle
48 for a period, and then runs a graphics demo chosen at random. The demo is
49 terminated as soon as there is any mouse or keyboard activity (or, in
50 locking mode, when the proper password is typed.)
52 It is trivially easy to add new display modes to xscreensaver: any program
53 which can be invoked in such a way that it draws on the root window of the
54 screen can be used as a screensaver. You just change a config file --
55 there's no need to recompile or reinstall anything.
59 Along with the xscreensaver daemon itself, this package also includes
60 numerous graphics hacks for use as screensavers. There is nothing
61 magic about these: they are just programs that draw on the root window.
62 More than 150 such programs are included. For details, see the
63 xscreensaver web page, or the enclosed manual pages.
65 The latest version of xscreensaver is always available on the web at
66 http://www.jwz.org/xscreensaver/.
68 Looking for tips on writing your own screensavers? There is an entry in
69 the XScreenSaver FAQ about that: http://www.jwz.org/xscreensaver/faq.html
73 Changes since 4.08: * New hacks, `flyingtoasters', `bouncingcow',
74 `jigglypuff', and `glslideshow'.
75 * More models in `engine'.
76 * Rewrote `xscreensaver-getimage' to remove reliance on
77 external image loaders (xv, chbg, xloadimage, etc.)
78 and to reduce flicker when loading files.
79 * Made `gflux' and `flipscreen3d' be mouse-spinnable.
80 Changes since 4.07: * New hacks, `atunnels' and `piecewise'.
81 * Physics improvement in `fluidballs'.
82 * Various fixes for XDarwin systems (X11 on MacOS X.)
83 * Added -clock option to `barcode'.
84 * Minor fixes to `endgame', `flurry', `flipscreen3d',
86 Changes since 4.06: * New hacks, `flurry', `metaballs', `eruption',
87 `popsquares', and `barcode'.
88 * Minor updates to `maze' for high density mazes.
89 * Added double buffering to `fluidballs' and `whirlygig'.
90 * Bug fixes for running xscreensaver to a remote XFree86
91 display (which nobody would ever do...)
92 * Updated `webcollage' (faster Alta Vista searching.)
93 * Updated `glplanet' so the sun sets in the west.
94 * Updated `sproingies' with smooth, unsegmented surfaces.
95 * Fixed Perl version-sensitivity in
96 `xscreensaver-getimage-file'.
97 * Fixed GTK2 scrolling bug in `xscreensaver-demo'.
98 Changes since 4.05: * New hack, `glblur' (disabled by default, since it
99 requires fast OpenGL texture support.)
100 * New hack, `halftone'.
101 * Updates to `endgame', `queens', `bumps', `glplanet',
102 `engine', and `circuit'.
103 * New version of `menger' that uses far fewer polygons.
104 * Fixed minor bug in `critical' that could cause some
105 bogus X servers to crash.
106 * Better labels in `molecule': the labels now appear to
107 be attached to the atoms, instead of floating in front
109 * Fixed bug that could rarely cause GL hacks to fail to
110 double-buffer (causing intermittent flickering.)
111 * Fixed a relative-URL-parsing bug in `webcollage'.
112 * Fixed a bug that (sometimes) caused the window manager
113 close box to kill `xscreensaver-demo' with a crash
114 instead of a graceful exit.
115 * Updated xscreensaver.pam to the Red Hat 7.3 way.
116 * More Gnome2-related configure crap.
117 * Updated to latest `config.guess' and `config.sub'.
118 * Fixed occasional core dump in `distort'.
119 * Added a Linux fsck failure and kernel panic to `bsod'.
120 * Added MacOS X kernel panic to `bsod'.
121 * Fixed a bug in `bsod' (all bsod bugs are ironic.)
122 * Fixed a bug that caused `xscreensaver-gl-helper' to
123 print a nonsense visual ID with some versions of
124 `printf': this could cause GL programs to display
125 incorrectly (e.g., flickery.)
126 Changes since 4.04: * More `configure' tweaks to try and get things working
127 on systems that both Gtk 1.x and 2.x installed.
128 * New hack, `endgame'.
129 * Minor updates to `gltext'.
130 Changes since 4.03: * Support for GTK 2.x / GNOME 2.x.
131 * The `configure' script will now use `pkg-config' if
132 you have it, in preference to `gtk-config', etc.
133 * New hacks, `lavalite', `queens', and `anemone'.
134 * Minor updates to `spheremonics', `gltext', `xmatrix'.
135 * You can use the mouse to manually spin most of the GL
136 hacks now (when they are displaying in a window.)
137 * Fixed a bug in `webcollage' (due to recent Alta Vista
138 url changes) that was causing it to try and load
139 incorrect image URLs.
140 * Made `xscreensaver-getimage' use gdk_pixbuf if it is
141 available: this means that those hacks that load images
142 will no longer rely on "xv", "xloadimage", etc. This
143 will close a race condition that could sometimes cause
144 your desktop background to be changed; and also makes
145 it possible for those programs to operate on image
146 files when running in windowed mode.
147 * `webcollage' can now be used in conjunction with
148 `driftnet' to display images snooped from your local
149 ethernet instead of obtained from search engines.
150 * Added man pages for all the hacks that didn't have
152 Changes since 4.02: * New hack, `spheremonics'.
153 * Minor updates to `webcollage', `cage', `moebius',
154 `morph3d', `boxed', `circuit', and `helix'.
155 * `pulsar' and `extrusion' can now load texture JPEGs.
156 * `rubik' now does non-square cubes.
157 * `fluidballs' now does various sizes of balls.
158 * `menger' and `sierpinski3d' now also show polygon
160 * `molecule' displays real subscripts in the formulae.
161 * GTK internationalization/localization support.
162 * Better detection of the various versions of libxml.
163 * Upgraded to autoconf 2.53 (from 2.13.)
164 Changes since 4.01: * Plugged a few minor leaks in `xscreensaver' and
166 * New hacks, `cubenetic' and `fluidballs'.
168 * Fixed sphere projection error in `glplanet'; installed
169 a better image of earth.
170 * Added Win2K and MacOS 1 crashes to `bsod'.
171 * Put back previous (better) version of `forest' that
172 was accidentially downgraded in the last release.
173 * New version of `bumps'.
174 * Made FPS computation in GL hacks more efficient: it
175 will influence the results less, thus resulting in
176 higher (but more accurate) reported frame rates.
177 Changes since 4.00: * New hacks: `twang', `glsnake', `boxed', `sballs',
179 * New hacks `apollonian', `euler2d', `juggle',
180 `polyominoes' and `thornbird', from xlockmore.
181 * Merged recent xlockmore changes into `ant', `braid',
182 `demon', `discrete', `drift', `fadeplot', `forest',
183 `grav', `hopalong', `ifs', `laser', `lightning',
184 `lisa', `lissie', `loop', `mountain', `penrose',
185 `rotor', `sierpinski', `slip', `sphere', `spiral',
186 `strange', and `vines'.
187 * Fixed the `gltext' bug that sometimes caused
188 horizontal lines to vanish again. This time for sure.
189 * Sped up `webcollage' by adding a C helper program to
190 replace the PPM pipeline. It also pastes images
191 semi-transparently now.
192 * Added support for the gdk_pixbuf library: if this lib
193 is available, then `blitspin', `xflame', and `flag'
194 can load GIF, JPEG, and PNG images in addition to XPM
196 * Fixed a rare race condition where the desktop-grabbing
197 hacks could sometimes leave the screen wedged, if the
198 user moved the mouse exactly when they were grabbing
199 the screen image (it would un-wedge the next time the
200 saver timed out or was activated.)
201 * Fixed incorrect colors in the screen-grabbing GL hacks
202 (`gflux' and `flipscreen3d'.)
203 * Made SIGHUP restart the daemon process (though using
204 `xscreensaver-command -restart' is still the preferred
206 * Tweaks to `xspirograph'.
207 * Minor configure and portability tweaks.
208 Changes since 3.34: * Redesigned `xscreensaver-demo' GUI: it now includes
209 small-preview and per-hack configuration dialogs.
210 * Added three new modes of operation: `One Screen Saver',
211 `Blank Screen', and `Don't Blank' (in addition to the
212 historical `Random Screen Saver').
213 * Configure now defaults to installing the hacks in
214 <prefix>/lib/xscreensaver/ instead of <prefix>/bin/.
215 (Most distros already did it this way.)
216 * New GL hacks, `menger', `engine', `flipscreen3d'.
217 * Made `sierpinski3d' be more colorful.
218 * New versions of `xmatrix' and `nerverot'.
219 * Fixed a bug in `starwars' that made the font be drawn
220 with thin lines in -root mode.
221 * Fixed a bad colormap bug in `crystal' that could make
222 *subsequent* hacks malfunction!
223 * Made `gflux' able to grab screen images (`-mode grab').
224 * Updated `webcollage' for recent search engine changes.
225 * Removed most command-line options to `xscreensaver':
226 just edit the ~/.xscreensaver file instead.
227 * Improved behavior on multi-screen and Xinerama systems:
228 the mouse now stays on the screen where the user left
229 it, and the password and splash dialogs always appear
230 on the screen that has the mouse.
231 * Made the splash dialog use more Gtk-like colors;
232 made it have only two buttons, "Settings" and "Help".
233 * Made `sonar' understand `.ssh/known_hosts2' format
234 files, and be better about stripping out illegal
236 Changes since 3.33: * Turned `memoryLimit' off by default, sigh. Apparently
237 some versions of the GL libraries (appear to) allocate
238 hundreds of megs for every GL program, so `memoryLimit'
239 was causing GL programs to malfunction or crash on
241 * Improved fading on TrueColor XFree86 4.1.x systems.
242 * New GL hack, `circuit'.
243 * Added `fuzz' mode to `decayscreen'.
244 * New version of `whirlygig'.
245 * Added links to `xplanet' and `sphereEversion'.
246 * Fixed rare race condition that could make `sonar' hang.
247 * Fixed potential crash in `speedmine'.
248 * Made `xscreensaver-demo' not crash when imageDirectory
249 was set to a non-existent directory.
250 * Made `xscreensaver-getimage-video' invoke XawTV's
251 `streamer' program better.
252 * Made `phosphor' and `starwars' deal with CR, LF,
253 or CRLF line endings.
254 * Changes for Cygwin compilation environments.
255 * Made `sonar' compile on systems that can't ping.
256 * Configure changes for HPUX 10.20.
257 * Made PAM code work on Red Had 4.2 systems.
258 * Made `xscreensaver-command -deactivate' work when the
259 saver is not active: what that does is reset the idle
260 timer, as if keyboard input had been detected. This
261 was added for the benefit of people writing DVD-playing
262 software: they can now prevent the screensaver from
263 kicking in by sending a -deactivate message once a
264 minute while the movie is playing and not paused.
265 * Various minor portability tweaks.
266 Changes since 3.32: * New hacks, `speedmine' and `whirlygig'.
267 * Sped up `pyro', made the explosions look a bit better.
268 * Added better stars to `glplanet' and `starwars'.
269 * Many internal changes to `webcollage'.
270 * Some new options to `attraction'.
271 * Minor fix to `noseguy' to avoid un-erased pixels.
272 * Rewrote the screen-eraser effects so that they complete
273 in the same amount of time regardless of how slow
274 your X server is (some of them were glacial on servers
276 * Fixed a potential free memory reference that could
277 sometimes cause a crash at startup.
278 * Possibly fixed a problem that could cause the daemon
279 to crash with an X error. I was never able to
280 reproduce this problem, but I think I might have
281 figured out what caused it.
282 * Worked around a problem that caused PAM authentication
283 to fail on some Red Hat 7.x systems.
284 * Added a `memoryLimit' parameter that controls the
285 amount of memory a graphics hack may allocate: if they
286 try to allocate more than this, malloc() will fail
287 (and they will exit or (safely) crash, rather than
288 hogging memory.) Default is 50M.
289 * Made `gnome-help-browser' be the default way to display
290 man pages in `xscreensaver-demo', if running on a
292 Changes since 3.31: * The image-manipulating hacks (`slidescreen', etc.) can
293 now operate on randomly chosen image files from disk,
294 or on frames captured from the system's video input,
295 instead of (or in addition to) manipulating images of
297 * Rewrote `vidwhacker' to use the new image-grabbing
299 * Made fading work on TrueColor XFree86 4.x systems.
300 * Fixed a subtle rendering bug in `atlantis' (the fish
302 * Made `atlantis' have a texture simulating light
303 reflections from the surface of the ocean.
304 * Fixed up label placement in `molecule'.
305 * Better color bars in `xteevee'.
306 * Made `install-strip' not try to strip scripts.
307 Changes since 3.30: * Put in more sensible defaults for DPMS, and updated
308 the documentation to reflect the fact that all your
309 DPMS settings are now belong to xscreensaver.
310 * Fixed the `xscreensaver.spec' file so that `--force'
312 * New versions of `rotzoomer' and `nerverot'.
313 * Fixed an OSF/1 compilation problem in `molecule'.
314 Changes since 3.29: * New hacks, `molecule', `dangerball', and `rotzoomer'.
315 * New version of `gflux'.
316 * Made `gltext' able to display the current time.
317 * Fixed a floating-point-precision problem in `gltext'
318 that sometimes caused horizontal lines to vanish.
319 * Removed the `-window-id' option from the hacks:
320 it never worked right, and was unnecessary.
321 * Made the `starwars' hack use thicker lines, antialias
322 the text, and fade out at the far edge instead of just
324 * Fixed an SHM segment leak in `moire'.
325 Changes since 3.28: * Better rendering of the new logo.
326 * New hack, `gltext'.
327 * Added `-planetary' option to `gears', to draw a
328 different kind of gear system.
329 * Made motion and rotation be smoother in `gears',
330 `glplanet', `moebius', `rubik', and `sierpinski3d'.
331 * Improved coloration in `sierpinski3d'.
332 * Made the GL hacks react to window size changes.
333 * Made most of the GL hacks take a -fps option (like
334 `pulsar' did), so you can use them to benchmark your
336 * Fixed the previous fix to `sonar'.
337 * Minor fix to `nerverot'.
338 Made sonar able to ping hosts on DEC OSF1.
339 * Eliminated a bogus "didn't get enough colors" warning
340 in some of the hacks.
341 Changes since 3.27: * New logo for xscreensaver!
342 * New hacks, `starwars' and `stonerview'.
343 * Made the motion of the bouncing ball in `stairs' be a
345 * Made newly-added screenhacks be added to .xscreensaver
346 automatically: if there are hacks in the app-defaults
347 file that are not also in ~/.xscreensaver, they will
348 be added to the end of the list.
349 * Redid the `Screensaver Options' part of the control
350 panel; xscreensaver now lets you configure your DPMS
352 * Fixed some Makefile problems with non-GL builds.
353 * Fixed detection of MesaGL for version 3.3.
354 * Better workaround to Red Hat 7.0's broken gcc.
355 * Added Sparc Solaris kernel panic to `bsod'.
356 Changes since 3.26: * New hacks: `zoom' and `whirlwindwarp'.
357 * Fixed a free-memory-reference bug in `sonar'.
358 * Better error handling when there are no suitable GL
360 * Added diagnostic dialog when xscreensaver-demo is
361 unable to launch xscreensaver (e.g., when running as
363 * Fixed a bug that caused screenhack argument changes
364 to be ignored when xscreensaver-demo was running as
365 root (if "root" and "nobody" have different home
367 * Made the programs default to ":0" if $DISPLAY is unset.
368 * Made the `-verbose' output include information about
369 which server extensions were supported at compile time.
370 * Worked around Red Hat 7.0's broken gcc 2.96.
371 * Updated default delays on the GL hacks to look better
372 on machines with super-fast 3D hardware.
373 * Install `screensaver-properties-capplet' to work around
374 the usual egregious GNOME lossage.
375 Changes since 3.25: * Added "enabled" checkboxes in the list of hacks in
376 xscreensaver-demo (Gtk version only.)
377 * New hacks `hyperball', `xrayswarm', and `gflux'.
378 * New versions of `nerverot', `galaxy', and `hypercube'.
379 * Small fixes to `phosphor', `shadebobs', `xflame',
381 * Added external helper program `xscreensaver-gl-helper'
382 to figure out which X visual to use for OpenGL
384 * Configure updates for XFree86 4.0, and for BSD.
385 * Made it be more tolerant of bogus /etc/group files.
386 * When installing the PAM config file, first try to just
387 copy an existing "xdm" or "login" config file, so that
388 xscreensaver does authentication in the same way as the
390 Changes since 3.24: * New hack, `nerverot'.
391 * Added BSD kernel panic to `bsod'.
392 * New version of `shadebobs'.
393 * New version of `petri'.
394 * Updated `webcollage' to handle recent Altavista URL
395 format changes; made it search the AP photo gallery.
396 * Revamped command-line options of `sonar' and made it
397 properly handle subnets.
398 * The `bubbles' hack can now trickle up or down the
400 * The `xsublim' hack can now read its text from programs.
401 * Support for GLE version 3 in `extrusion'.
402 * Fixed compilation problems in `maze'.
403 * Fixed a rare crash in `flow'.
404 * Fixes for minor installation problems.
405 Changes since 3.23: * Added `-ignorant' option to `maze' hack.
406 * Updates to `critical', `bsod', `xflame', and `flow'.
407 * Added support for Kerberos 5 (via its Kerberos 4
408 compatibility layer.)
409 * Fixed a bad leak in `xteevee'.
410 * Updated `webcollage' to handle recent Altavista URL
412 * Removed xscreensaver-demo's `Ok' and `Cancel' buttons,
413 since they were confusing people: all changes are now
415 * Made xscreensaver-demo install itself into the Gnome
417 Changes since 3.22: * Fixed some misplaced text fields in the Motif version
418 of xscreensaver-demo; fixed a crash in the Gtk version
419 that would happen if the programs list was empty.
420 * Fixed a recently-introduced bug in `pulsar'.
421 * Made `sierpinski3d' use solid tetrahedrons instead of
423 * Added `-trace' option to `xmatrix'.
424 * Added new hacks `xteevee' and `xspirograph'.
425 Changes since 3.21: * Fixed some bugs in xscreensaver-demo.
426 * Rewrote the Motif version of xscreensaver-demo to
427 match the new Gtk version.
428 * The Athena toolkit is no longer supported.
429 Changes since 3.20: * Tweaked the xscreensaver-demo UI (Gtk only.)
430 * Fixed a few visual selection bugs. I think the proper
431 GL visual should be used with nVidia systems now.
432 * Made the Makefiles obey $install_prefix.
433 * Made the `xscreensaver.spec' file able to generate both
434 GL and non-GL packages simultaneously.
435 Changes since 3.19: * Added new hacks `ripples' and `sierpinski3d'.
436 * Made `xscreensaver-command -exit' be silent when no
437 screen saver was running (instead of complaining.)
438 * Made `webcollage' and `vidwhacker' use `xloadimage'
439 when available (in addition to `xli' and `xv'.)
440 * Improved memory usage in `petri' and gave it a hard
441 cap on how much memory it can allocate.
442 * Added `-watch' option to `xscreensaver-command'.
443 * Made `xscreensaver-demo' come up with the
444 most-recently-run hack selected by default.
445 * Rewrote the Gtk version of `xscreensaver-demo'.
446 It's a lot easier to use now.
447 * Extended the format of the programs list in the
448 .xscreensaver file, for the benefit of the new
449 capabilities of `xscreensaver-demo'.
450 NOTE: you might want to delete your ~/.xscreensaver
451 file and allow it to be re-created! The old one
452 should still work, but xscreensaver-demo won't be as
454 Changes since 3.18: * Fixed gcc dependencies in `bumps' and `ccurve'.
455 * New hack, `extrusion'.
456 * Some of the web sites that `webcollage' was using as
457 its sources changed formats; tweaked it to understand
459 * Added typeahead in the password dialog: if the screen
460 is locked, and you unlock it by typing a character,
461 that key will be automatically inserted in the
462 password dialog (unless it is Return, Enter, Space,
463 or a non-printing key like Shift.)
464 * Made `xmatrix' take a `-small' option, since some
465 folks with tiny screens prefer a smaller font.
466 Changes since 3.17: * New versions of `shadebobs', `lmorph', and `distort'.
467 * Added `ccurve', `blaster', and `bumps' hacks.
468 * Replaced `forest' hack with a rewritten version.
469 * Worked around a Xinerama server bug.
470 * Fixed a bug I introduced in 3.10 that caused some
471 hacks to print out superfluous warnings about not
472 having gotten enough colors.
473 * Made `sproingies' obey the `-delay' option.
474 * Fixed a portability bug in `shadebobs'.
475 * Made `webcollage' and `vidwhacker' use `xli' in
476 preference to `xv', if it is available.
477 * Added a new source of images to `webcollage'.
478 * If running under KDE, xscreensaver will add itself to
479 KDE's list of screensavers (via xscreensaver.kss.)
480 * Improved detection of GL libraries.
481 * Made the password dialog include the date and time.
482 Changes since 3.16: * New version of `webcollage' -- deals better with
483 corrupted images, and can use an http proxy.
484 * New hack, `xsublim' (run it in the background,
485 rather than adding it to the programs list.)
486 * The xscreensaver daemon was leaking a file descriptor
487 each time you edited your .xscreensaver file. Fixed.
488 Changes since 3.15: * New version of `shadebobs'.
489 * Improved image selection in `webcollage', and sped it
491 * Made configure find the right version of perl.
492 * Rewrote the CGI part of `webcollage'.
493 * `make clean' was deleting some things it shouldn't.
494 * Fixed a typo in the default programs list.
495 Changes since 3.14: * Added `webcollage' and `shadebobs' hacks.
496 * Added a `-stdout' arg to `vidwhacker' so that it can
497 be used in a pipeline.
498 * Made `petri' use less memory.
499 Changes since 3.13: * Various improvements to the Gtk port.
500 * Turned off PAM by default on Solaris, since PAM seems
501 generally to be misconfigured out-of-the-box.
502 * Made the `--without-gtk' configure option work.
503 * Made configure check the Gtk version number, since it
505 * Fixed a bug in the code that attempted to prevent
506 changes of screen resolution while the screen is
508 * Fixed a race condition in `xscreensaver-demo' that
509 could cause an X error at startup.
510 * Added `-transparent' option to `deluxe'.
511 * Added `petri' hack.
512 Changes since 3.12: * Ported `xscreensaver-demo' to Gtk.
513 * Made it possible to build Motif, Gtk, and Athena
514 versions of `xscreensaver-demo' in the same directory
515 without reconfiguring.
516 * Made `xscreensaver-demo' chase symlinks before writing
517 the .xscreensaver file, so that if .xscreensaver is
518 itself a symlink, the underlying file will be replaced
520 * Some Makefile and configure tweaks for Solaris and
522 * Made it possible to set the fire color in `xflame'.
523 * Made transparency work in TrueColor (for `goop' and
525 * Fixed a multi-head bug introduced by the virtual
527 Changes since 3.11: * Made it so that you can't scroll the screen while the
528 lock dialog is up (with XFree86 virtual viewports.)
529 * Fixed a bug in `flag' that caused bob's chin to get cut
530 off after a few iterations.
531 Changes since 3.10: * Made `xjack' be black-on-white-ish, so that it looks
532 less like a computer screen and more like the
533 typewritten paper it's supposed to be.
534 * New version of `pulsar'.
535 * Fixed Solaris compilation problem in `phosphor'.
536 * Made xscreensaver notice XFree86's virtual root window
537 hack, so that if the X server's root window is larger
538 than the monitor's displayable resolution, the screen
539 saver will limit itself to the area that actually
540 appears on the screen.
541 * Made the xscreensaver daemon do a better job of
542 picking the visual class that should be used for GL
543 programs. Less user intervention should be needed
544 now: you can use the logical visual name `GL' instead
545 of having to figure out by hand which one to use.
546 * Oops, the visual was defaulting to "best" instead of
547 "default", because the .xscreensaver file was not being
548 loaded quite early enough.
549 * Made configure figure out how to build icmp ping
550 support into the `sonar' hack automatically.
551 * Made warnings about not being able to read shadow
552 passwords not be printed if compiled with PAM support.
553 * Improved PAM startup diagnostics.
554 * Worked around the Solaris PAM bug that was causing
555 crashes there, so now PAM is turned on by default.
556 * Made configure detect the number of arguments that
557 pam_strerror() takes, since on Linux, this apparently
558 changed between 2.0 and 2.2, sigh.
559 * Made the /proc/interrupts kludge look for "PS/2 Mouse"
560 as well as "keyboard".
561 * Made xscreensaver notice when there has been a sudden
562 large jump in wall-clock time, and if so, lock right
563 away, instead of waiting for "lockTimeout" to expire
564 first. (Laptops need this for safer recovery from
566 * Added `-throttle' option to `xscreensaver-command'.
567 Changes since 3.09: * Added `phosphor', `xmatrix', and `pulsar' hacks.
568 * Fixed a bug in the color allocator that sometimes
569 caused `starfish' to fall back to monochrome.
570 * Reduced the amount of code that runs before root
571 privileges are disavowed: "normal" and "shadow"
572 passwords now do some initialization as root, but the
573 PAM and Kerberos authorization schemes will be
574 initialized while running as "nobody". Supposedly
575 this closes a potential security hole when using
577 * Added some more sanity checking to configure.
578 Changes since 3.08: * Added `compass', `squiral', `xflame', `wander',
579 `spotlight', and `critical' hacks.
580 * Added some new modes to `decayscreen'.
581 * Made `deluxe' work in monochrome.
582 * Generalized usage of the Double-Buffer server extension
583 in several hacks (`compass', `deluxe', `interference',
584 `kumppa', and `moire2'.)
585 * Fixed another visual-depth problem in `rd-bomb'.
586 * The screen saver will now defer blanking if neither
587 the keyboard nor the mouse could be grabbed. Instead,
588 it will just try again in a few minutes. This fixes
589 a bad interaction between xscreensaver and programs
590 like VMware that hold the mouse and keyboard grabbed
592 * Added a new erase mode (expanding spiral.)
593 Changes since 3.07: * Fixed some bugs in my port of `t3d'.
594 * Added `penetrate' and `deluxe' hacks.
595 * When linking against Motif 2.x, also link against XPM.
596 * Added support for using /proc/interrupts for idle
597 detection on Linux. Now xscreensaver shouldn't kick
598 in when the user is active on a non-X virtual console.
599 * Upgraded to autoconf 2.13.
600 Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
601 in properly; check for _Xsetlocale in -lXintl.)
602 * Portability fixes for sonar.c.
603 * Fixed a compilation problem when you have GL but don't
605 * Made configure notice when MesaGL requires -lpthread.
606 * Made `flame' ignore SIGFPE (not sure if this is the
607 right fix; it seems only to be needed on FreeBSD.)
608 * Kludged `rd-bomb' work on visuals that are of depth 24
609 but that *do not* support pixmaps of depth 32.
610 * Fixed `halo' to work properly in TrueColor.
611 * Changed `xscreensaver.spec' to install the hacks in
612 /usr/X11R6/lib/xscreensaver/ by default, since that's
613 where recent Red Hat distributions put them.
615 * Updated versions of `crystal', `hopalong', and `flow'
617 * Imported `demon' and `loop' modes from xlockmore.
618 Changes since 3.05: * Oops, the "default-n" visual descriptor was broken;
619 it was always installing a colormap if the
620 `installColormap' preference was set, meaning that
621 `xearth', `xv' and friends were using the wrong
622 colors on 8-bit systems.
623 * Turned off HAVE_PING in `sonar', since it compiles
624 on some Linux systems, but not others of similar
626 Changes since 3.04: * Fixed an off-by-1 in `distort'.
627 * Added `sonar' hack.
628 * New version of `glplanet' (with stars.)
629 * Made all hacks exit when you type `q' or `ESC' at them,
630 and made them obey the WM_DELETE_WINDOW ClientMessage.
631 * Fixed a nonfatal buffer overrun in lament (note:
632 lament still doesn't work with MesaGL 3.0: it dies in
633 lambda_textured_triangle1(), which is Mesa's bug, not
635 Changes since 3.03: * Added an `xscreensaver.spec' file, to make it easier
636 for other folks to generate RPMs.
637 * Made the password code work on HPUX in the situation
638 where: ``enhanced security'' is available; but not
639 used; but the user typed a password more than 8
640 characters long anyway. FTSOHPUX.
641 Changes since 3.02: * Made locking work when passwd aging is enabled.
642 * Added support for PAM (Pluggable Authentication
643 Modules.) It is still turned off by default, though,
644 since it doesn't seem to work on Solaris 2.6, and has
645 been behaving erratically on Red Hat 5.1.
646 * Made each possible authentication method be tried in
647 turn until one succeeds; this means that Kerberos is
648 being used, we will first check Kerberos, and if that
649 fails, will then consult the local password file.
651 * Save and restore the bits under the passwd dialog,
652 to avoid leaving a black rectangle behind when
653 unlocking is cancelled.
654 Changes since 3.01: * Not everyone has sys/select.h, sigh...
655 Changes since 3.00: * Some fixes to `reflect'.
657 * Made it log unsuccessful attempts to unlock the screen
659 * Fixed a bug where `xscreensaver-demo' could be seeing
660 a different programs list than `xscreensaver' did.
661 Changes since 2.34: * The xscreensaver daemon no longer links against Motif
662 or Athena: demo-mode and the preferences panel are no
663 longer built in to the daemon, but are now handled by
664 an external program, `xscreensaver-demo'.
665 (I decided that this, along with the recent addition
666 of the `.xscreensaver' config file, justified bumping
667 the version number to 3.00, since this is a fairly
668 major architectural change.)
669 * Lines in the `*programs' resource may now begin with
670 the character "-", meaning "don't run this hack."
671 In this way, it's possible to disable a hack without
672 throwing away the information about it (making it
673 easier to change your mind later.) Eventually the
674 preferences/demo mode GUI should represent this as a
675 checkbox or something.
676 * Fixed a short race condition where it was possible for
677 xscreensaver to die with a BadWindow error if it was
678 blanking the screen just as another window was being
680 * Made it possible to disable specific modes in `bsod'.
681 Changes since 2.33: * Fixed a bug that was making `pipes' generate way too
682 many valves. Made the viewpoint in `pipes' be selected
683 randomly instead of always being -10 degrees.
684 * Fixed a bug in the XSHM code, in the case where the
685 server supports the XSHM extension but is not the same
686 machine as the client.
687 * Made `rd-bomb' default to taking up the whole screen.
688 * Made it not try to do fading/unfading if no PseudoColor
690 * Initial attempt at supporting VT-locking (doesn't work
692 * Eliminated the `captureStdout' resource; now
693 `captureStderr' controls both streams.
694 * Added `-capture-stderr' and `-no-capture-stderr'
695 command-line arguments.
696 * Added `glplanet' hack.
697 * When a hack is selected with `xscreensaver-command
698 -select', that hack will be used until further notice
699 (until the saver turns off, or another activation
701 Changes since 2.32: * Made `xscreensaver-command' print error messages:
702 the xscreensaver daemon now responds to ClientMessage
703 events by writing a response message on a window
704 property, instead of just writing to its stderr.
705 * Made the ~/.xscreensaver file be automatically reloaded
706 when the file date changes.
707 * The password dialog and splash screen no longer depend
708 on Motif or Athena. This should clear up a number of
709 focus problems, and is the first step on the path
710 toward moving all of the Motif/Athena/whatever code
711 out of the xscreensaver daemon, and into external
713 * Don't complain about LessTif 0.86 any more, since the
714 new password dialog makes that problem go away.
715 * Configure tweaks for Irix 6.5, SunOS 5.something.
716 * New `-reflect' option to `distort'.
717 Changes since 2.31: * Added reading and writing of a ~/.xscreensaver file,
718 so that the Preferences panel can save its settings.
719 * New version of `rubik'.
720 * Added `-select N' argument to `xscreensaver-command'.
721 * Oops, left out some of the `bubbles3d' files...
722 Changes since 2.30: * The cursor was invisible in the password dialog. Fixed.
723 * Made configure warn against MesaGL 2.6.
724 * Fixed X error at startup when using non-default visual.
725 * New version of `crystal', `ant', and `atlantis' from
727 * New hack, `bubble3d'.
728 * Added some new modes to `bsod'.
729 Changes since 2.29: * Changed the order in which -lSM and -lICE are linked
730 to be after Motif instead of before (Lesstif on Irix
732 Changes since 2.28: * Work around a bash bug in configure.
733 * Tweaked HPUX paths again. FTSOHPUX.
734 * Made configure recommend against LessTif 0.86, due
735 to a bug in that version that causes a security hole
736 in the screen locking code. LessTif 0.87 will fix it.
737 * Made all of the `--with' options to `configure' accept
738 a directory option as well (so that --with-motif=/FOO
739 will add -I/FOO/include -L/FOO/lib). I believe this is
740 the Configure Party Line of how do to such things.
741 * Fixed a bug where the mouse was left un-grabbed
742 after the first time the graphics hack was changed
743 (simplified all of the mouse-grabbing logic.)
744 * Maybe possibly perhaps made `vidwhacker' really not
745 leave stray xv windows around. This time for sure.
746 * Added a new erase mode (random dots fizzling out.)
747 * Added `-prefs' argument to `xscreensaver-command',
748 that brings up the Preferences dialog directly (it
749 seems that nobody ever noticed the `Preferences' button
750 on the Demo Mode dialog, maybe this will help.)
751 * Added a splash screen. Turn it off with *splash:false.
752 Changes since 2.27: * Better macsbug text in `bsod'.
753 * New version of `distort' with many new modes.
754 * Plugged a leak in `coral'.
755 * Tweaked configure for HPUX.
756 * Removed some compiler warnings.
757 * More consistent usage of stderr versus stdout.
758 * More diagnostics should an X error occur.
759 * Fixed a possible crash in SGI-specific unfading code.
760 Changes since 2.26: * Improved version of `distort'.
761 * Made `lament' compile against OpenGL 1.0 (though it
762 still requires 1.1 to work properly.)
763 * Updated my email address and home page.
764 Changes since 2.24: * Improved motion in `rd-bomb'.
765 * Added XSHM (shared memory extension) support to the
766 `distort', `interference', `moire', `rd-bomb', and
767 `swirl' hacks, which speeds them up a bit.
768 * Added `lament' hack.
769 Changes since 2.23: * Tweaked the order of the -L options again.
770 * Cleaned up configure's `--help' message.
771 * Added `kumppa' hack.
772 * Smarter maze-solving algorithm in `maze'.
773 * Took `xlyap' out of the default list of hacks, since
774 it's just incredibly buggy (and slow.) Maybe someday
775 someone will fix it...
776 * Added `distort' hack, but didn't add it to the default
777 list (yet) because it's still too slow.
778 * Made the Athena demo dialog look more like the Motif
779 version; it has a text-entry field now, too.
780 * Made the Athena password dialog echo asterisks, like
781 Motif does, instead of using a flyspeck font.
782 * Some random configure tweaks.
783 * Added a `timestamp' resource that makes the `-verbose'
784 messages include the time at which they were printed.
785 Changes since 2.22: * The fix for SGI's ``scheme'' nonsense broke things, and
786 let the user's "*background" resource show through.
787 Fixed it in a different way.
788 Changes since 2.21: * Added support for the DPMS server extension (Display
789 Power Management System.)
790 * Made configure advertize the `--enable-subdir' option a
791 little more, since that seemed to cause some people
792 stress. Also, made that directory be built into the
793 xscreensaver executable, as a hardcoded prefix to
794 $PATH. (Might help, shouldn't hurt.)
795 * Made configure prefer the two-arg gettimeofday to the
796 one-arg version, since AIX doesn't have any prototypes.
797 * Made it work with Xaw3d (the 3D Athena library.)
798 * Made `make install' create directories as necessary.
799 * New version of lmorph from Sverre.
800 * Added `crystal' and `discreet' hacks from xlockmore.
801 * Added a new mode to `bsod'.
802 Changes since 2.20: * Made `xscreensaver-command -time' use different words.
803 (It now describes the two states as "screen blanked
804 since..." and "screen non-blanked since..." instead of
805 "active since..." and "inactive since..." which a lot
806 of people interpreted as meaning the opposite of what
808 * Improved some error messages, in the hopes of making
809 the distinction between the xscreensaver and
810 xscreensaver-command programs more obvious.
811 * Rewrote (and reorganized) parts of the xscreensaver and
812 xscreensaver-command manual pages.
813 * Renamed xscreensaver's `-lock' command-line option to
814 be `-lock-mode', to avoid confusion with the `-lock'
815 option to xscreensaver-command, which does a totally
817 * Removed xscreensaver's `-demo' command-line option for
818 a similar reason; use `xscreensaver-command -demo'
820 * Disabled SGI's ``scheme'' nonsense in a better way than
821 fully-qualifying the background colors in every single
823 * Fixed some other minor cosmetic problems when *sgiMode
825 * Fixed an X error in `bsod -root' (how ironic...)
826 Changes since 2.19: * Fixed a bug that caused the mouse to sometimes not be
827 grabbed properly (meaning the window manager menu could
828 pop up over the demo-mode display.)
829 * Fixed a bug that made the stderr output sometimes get
831 * Fixed a bug that made the demo-mode scrollbar move too
833 * Protected against a possible buffer overflow.
834 * Made `vidwhacker' not leave stray xv windows around.
835 * New version of `ant' so that Bagley doesn't calve.
836 * Make configure on AIX get XShm from the right library.
837 Changes since 2.18: * One file was missing from the tar file. Fixed.
838 Changes since 2.17: * Oops, atlantis wasn't being built by default. Fixed.
839 * Added `epicycle' hack.
840 * Added `interference' hack.
841 * Added `truchet' hack.
843 * Added some new modes to `vidwhacker'.
844 Changes since 2.16: * Added a -window-id argument to most hacks, so that they
845 can draw on arbitrary externally-provided windows.
846 * Synched with xlockmore 4.11a01.
848 * Added `atlantis' GL hack.
849 * Renamed `puzzle' hack to `jigsaw', since xlock already
850 had a different mode called `puzzle'.
851 * Made it self-configure properly when Motif 2.1.0 is
852 being used (requires -lXp now, sigh...)
853 Changes since 2.15: * Made `flag' able to do XPM images.
854 * New look for the xscreensaver logo (`xroger').
855 * Fixed compilation error on Suns with adjunct passwords.
856 * Got multi-architecture builds working again.
857 * Some configure tweaks for building on HPUX and Solaris.
858 * Fixed bug in decayscreen.
859 * Fixed typo in passwd.c.
860 * Made `cynosure' not die when colormap is full.
861 Changes since 2.14: * Added `cynosure' hack.
862 * Added `moire2' hack.
863 * Tweaked `erase.c' some more.
864 * Made unfading a bit smoother.
865 * Added `vidwhacker' hack (not installed by default.)
866 * Added `stairs' hack.
867 * Split `escher' into `cage' and `moebius', as per
869 * Changed subprocess handling to use sigaction() instead
870 of signal() if it's available (this is necessary for
871 SCO but should work fine on other systems too.)
872 * Various other tweaks.
873 Changes since 2.13: * Better fix for the Motif drag-and-die lossage.
874 * Put in some kludges to work around a LessTif bug.
875 * XScreenSaver is known to work with LessTif 0.82 now.
876 * Made fading work on high-end SGI video hardware.
877 * Fixed another SGI-specific bug in screen grabbing;
878 will the madness never cease?
879 * Fixed another crash in `xlyap'.
880 Changes since 2.12: * Made `decayscreen' do directions other than down.
882 * Fixed a crash in `xlyap'.
883 * Added CDE info to the man page, removed `cde.txt'.
884 * Configure tweaks for Zippy.
885 * Turned off the signal handling in `bubbles' because
886 it was sometimes failing to die.
887 * Added `hacks/xscreensaver-sgigl.c' to make it possible
888 to run SGI's ElectroPaint hack (/usr/demos/bin/ep)
889 with xscreensaver. Finally!
890 * Fixed a buffer overrun in the locking code that some
891 wily, malicious cracker must have slipped in.
892 * Disabled Motif drag-and-drool in the dialog box
893 buttons, since it's broken in some old versions of
895 Changes since 2.11: * Added `README.debugging'.
896 * Added `puzzle' hack.
897 * Added `xlyap' hack.
898 * Added `default-n' as a visual name, so that one can
899 have -install on by default, but turn it off for
900 certain poorly-behaved hacks (like xv.)
901 * Added support for grabbing frames of external video
902 (on SGI) to the screen-grabbing hacks (decayscreen,
903 slidescreen, slip, blitspin, and puzzle.)
904 * Improved look of tiles in `slidescreen'; fixed its
905 color allocation problem.
906 Changes since 2.10: * Tweaked `blitspin', added it to the default list.
907 * Added `lissie', `mountain', `triangle', `worm',
908 `rotor', and `ant' from xlockmore.
909 * Updated `sierpinski', `galaxy', and `lisa'.
910 * Thickened the lines in `braid' and `lmorph'.
911 * Updated VMS makefiles.
912 * Renamed `fract' to `vines'.
913 * Added `xjack' hack.
914 * Made a few more hacks use erase.c, and added a few
916 * Fixed compilation problem with Sun's version of OpenGL.
917 * Added ability to use sigaction() instead of signal()
918 to work around a SCO kernel bug.
919 Changes since 2.09: * Fixed colormap bugs in `rd-bomb'; sped up `coral'.
920 * Configure tweaks for *BSD.
921 Changes since 2.07: * New hacks `rd-bomb' and `coral'.
922 * New version of `maze' with some new algorithms.
923 * New colorized version of `rocks'.
924 * Fixed a bug in qix on 64-bit machines.
925 * Fixed a bug in the -time option.
926 * Fixed a bug in configure related to LessTif.
927 Changes since 2.06: * Minor header tweaks in windows.c and flag.c.
928 * Made multi-architecture ($VPATH) builds work properly.
929 * Merged new GL stuff from xlockmore (rubik, morph3d.)
930 * Fixed intermittent crashes in `imsmap' and `munch'.
931 * Added `fadeplot' hack from xlockmore.
932 Changes since 2.05: * Merged in VMS support from Patrick Moreau.
933 Changes since 2.04: * Fixed a MIT-SCREEN-SAVER-related crash, and tweaked
934 configure to detect the extra-random -Xss library.
935 Changes since 2.03: * HP configure tweaks. Detect and warn about LessTif.
936 * Fixed low-color behavior of `goop', `pyro', `starfish',
937 `greynetic', `flame', `halo', and `moire'.
938 Changes since 2.02: * Fixed flicker in `pipes'. Fixed 3d in `bouboule'.
939 * Added `munch' hack.
940 * Added basic dependencies to the Makefile.in files.
941 Changes since 2.01: * Fixes for compiling with the MIT saver extension.
942 * Made the yow/fortune program be a configure option.
943 * Various configure tweaks.
944 Changes since 2.00: * Added `goop' and `starfish' hacks.
945 * Added colomap cycling to `halo'.
946 * Made `attraction' use the new colormap allocator.
947 * Added better $PATH diagnostics.
948 * There was a bug in frand! Color selection should be
950 Changes since 1.34: * Converted to use `configure' instead of `imake'.
951 * ANSI C is now required.
952 * Added Kerberos locking support, from Nat Lanza.
953 * Made the stderr text use overlay planes, if possible.
954 * Reworked the xlockmore compatibility stuff again.
955 * Added `gears', `superquadrics', `escher', `pipes',
956 and `sproingies' hacks (depend on OpenGL.)
957 Changes since 1.33: * Fixed some bugs, made fading be a little smoother.
958 Changes since 1.32: * Made it work with multi-headed displays.
959 * Generalized sub-process management (Unix sucks!)
960 * Added interactive mouse frobbing to Julia.
961 * Added (untested) support for HPUX shadow passwords.
962 * Made normal non-shadow passwords be checked if the
963 shadow passwords aren't accessible for some reason.
964 Changes since 1.31: * Removed *colorPrograms and *monoPrograms resources:
965 made it possible to specify the desired visual on a
967 * Cleaned up / restructured the driver: no more globals.
968 * Made the Motif and Athena dialogs share more code.
969 * Probably fixed some Athena colormap-installation bugs.
970 * Fixed screen grabbing (cmap) on SGI 12-bit PseudoColor.
971 * Fixed divide-by-zero in bright random colormaps.
972 * Added an improved version of xlock's `flag' hack.
973 * Made unfading work better, and not flicker on SGIs.
974 * Added `sphere', `forest', `lisa' hacks from xlockmore.
975 * Added (untested) support for SunOS Adjunct passwords.
976 Changes since 1.30: * Improved colors and colormap cycling of many hacks.
977 * Cleaned up xlockmore compatibility layer.
978 * Made `blitspin' able to grab an image off the screen.
979 * Ported `swirl' and `bouboule' hacks from xlockmore.
980 * Made the driver more careful about not leaving bits on
981 the screen, or allowing other windows to raise
982 themselves: it now re-blanks the screen every so often.
983 * Added `-time' option to `xscreensaver-command'.
984 * Improved SGI screen-grabbing some more: now it can grab
