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