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 are upgrading from version 2.* to version 3.*, be sure to delete
28 your ~/.xscreensaver file first, if you have one.
30 If you think you've found a bug, please let me know! No bug report is too
31 small. But first, please read the enclosed `README.debugging' file to find
32 out what kind of information would be most helpful to include in your bug
37 You can try out xscreensaver like so:
42 Note: unlike `xlock', xscreensaver has a client-server model: the
43 `xscreensaver' process is a daemon that runs in the background; it is
44 controlled by the foreground `xscreensaver-demo' program.
46 xscreensaver has an extensive manual -- please read it!
50 The xscreensaver daemon waits until the keyboard and mouse have been idle
51 for a period, and then runs a graphics demo chosen at random. The demo is
52 terminated as soon as there is any mouse or keyboard activity (or, in
53 locking mode, when the proper password is typed.)
55 It is trivially easy to add new display modes to xscreensaver: any program
56 which can be invoked in such a way that it draws on the root window of the
57 screen can be used as a screensaver. You just change a config file --
58 there's no need to recompile or reinstall anything.
62 Along with the xscreensaver daemon itself, this package also includes
63 numerous graphics hacks for use as screensavers. There is nothing magic
64 about these: they are just programs that draw on the root window.
66 More than 120 such programs are included. For details, see the xscreensaver
67 web page, or the enclosed manual pages.
69 The latest version of xscreensaver is always available on the web at
70 http://www.jwz.org/xscreensaver/.
74 Changes since 3.32: * New hacks, `speedmine' and `whirlygig'.
75 * Sped up `pyro', made the explosions look a bit better.
76 * Added better stars to `glplanet' and `starwars'.
77 * Many internal changes to `webcollage'.
78 * Some new options to `attraction'.
79 * Minor fix to `noseguy' to avoid un-erased pixels.
80 * Rewrote the screen-eraser effects so that they complete
81 in the same amount of time regardless of how slow
82 your X server is (some of them were glacial on servers
84 * Fixed a potential free memory reference that could
85 sometimes cause a crash at startup.
86 * Possibly fixed a problem that could cause the daemon
87 to crash with an X error. I was never able to
88 reproduce this problem, but I think I might have
89 figured out what caused it.
90 * Worked around a problem that caused PAM authentication
91 to fail on some Red Hat 7.x systems.
92 * Added a `memoryLimit' parameter that controls the
93 amount of memory a graphics hack may allocate: if they
94 try to allocate more than this, malloc() will fail
95 (and they will exit or (safely) crash, rather than
96 hogging memory.) Default is 50M.
97 * Made `gnome-help-browser' be the default way to display
98 man pages in `xscreensaver-demo', if running on a
100 Changes since 3.31: * The image-manipulating hacks (`slidescreen', etc.) can
101 now operate on randomly chosen image files from disk,
102 or on frames captured from the system's video input,
103 instead of (or in addition to) manipulating images of
105 * Rewrote `vidwhacker' to use the new image-grabbing
107 * Made fading work on TrueColor XFree86 4.x systems.
108 * Fixed a subtle rendering bug in `atlantis' (the fish
110 * Made `atlantis' have a texture simulating light
111 reflections from the surface of the ocean.
112 * Fixed up label placement in `molecule'.
113 * Better color bars in `xteevee'.
114 * Made `install-strip' not try to strip scripts.
115 Changes since 3.30: * Put in more sensible defaults for DPMS, and updated
116 the documentation to reflect the fact that all your
117 DPMS settings are now belong to xscreensaver.
118 * Fixed the `xscreensaver.spec' file so that `--force'
120 * New versions of `rotzoomer' and `nerverot'.
121 * Fixed an OSF/1 compilation problem in `molecule'.
122 Changes since 3.29: * New hacks, `molecule' `dangerball', and `rotzoomer'.
123 * New version of `gflux'.
124 * Made `gltext' able to display the current time.
125 * Fixed a floating-point-precision problem in `gltext'
126 that sometimes caused horizontal lines to vanish.
127 * Removed the `-window-id' option from the hacks:
128 it never worked right, and was unnecessary.
129 * Made the `starwars' hack use thicker lines, antialias
130 the text, and fade out at the far edge instead of just
132 * Fixed an SHM segment leak in `moire'.
133 Changes since 3.28: * Better rendering of the new logo.
134 * New hack, `gltext'.
135 * Added `-planetary' option to `gears', to draw a
136 different kind of gear system.
137 * Made motion and rotation be smoother in `gears',
138 `glplanet', `moebius', `rubik', and `sierpinski3d'.
139 * Improved coloration in `sierpinski3d'.
140 * Made the GL hacks react to window size changes.
141 * Made most of the GL hacks take a -fps option (like
142 `pulsar' did), so you can use them to benchmark your
144 * Fixed the previous fix to `sonar'.
145 * Minor fix to `nerverot'.
146 Made sonar able to ping hosts on DEC OSF1.
147 * Eliminated a bogus "didn't get enough colors" warning
148 in some of the hacks.
149 Changes since 3.27: * New logo for xscreensaver!
150 * New hacks, `starwars' and `stonerview'.
151 * Made the motion of the bouncing ball in `stairs' be a
153 * Made newly-added screenhacks be added to .xscreensaver
154 automatically: if there are hacks in the app-defaults
155 file that are not also in ~/.xscreensaver, they will
156 be added to the end of the list.
157 * Redid the `Screensaver Options' part of the control
158 panel; xscreensaver now lets you configure your DPMS
160 * Fixed some Makefile problems with non-GL builds.
161 * Fixed detection of MesaGL for version 3.3.
162 * Better workaround to Red Hat 7.0's broken gcc.
163 * Added Sparc Solaris kernel panic to `bsod'.
164 Changes since 3.26: * New hacks: `zoom' and `whirlwindwarp'.
165 * Fixed a free-memory-reference bug in `sonar'.
166 * Better error handling when there are no suitable GL
168 * Added diagnostic dialog when xscreensaver-demo is
169 unable to launch xscreensaver (e.g., when running as
171 * Fixed a bug that caused screenhack argument changes
172 to be ignored when xscreensaver-demo was running as
173 root (if "root" and "nobody" have different home
175 * Made the programs default to ":0" if $DISPLAY is unset.
176 * Made the `-verbose' output include information about
177 which server extensions were supported at compile time.
178 * Worked around Red Hat 7.0's broken gcc 2.96.
179 * Updated default delays on the GL hacks to look better
180 on machines with super-fast 3D hardware.
181 * Install `screensaver-properties-capplet' to work around
182 the usual egregious GNOME lossage.
183 Changes since 3.25: * Added "enabled" checkboxes in the list of hacks in
184 xscreensaver-demo (Gtk version only.)
185 * New hacks `hyperball', `xrayswarm', and `gflux'.
186 * New versions of `nerverot', `galaxy', and `hypercube'.
187 * Small fixes to `phosphor', `shadebobs', `xflame',
189 * Added external helper program `xscreensaver-gl-helper'
190 to figure out which X visual to use for OpenGL
192 * Configure updates for XFree86 4.0, and for BSD.
193 * Made it be more tolerant of bogus /etc/group files.
194 * When installing the PAM config file, first try to just
195 copy an existing "xdm" or "login" config file, so that
196 xscreensaver does authentication in the same way as the
198 Changes since 3.24: * New hack, `nerverot'.
199 * Added BSD kernel panic to `bsod'.
200 * New version of `shadebobs'.
201 * New version of `petri'.
202 * Updated `webcollage' to handle recent Altavista URL
203 format changes; made it search the AP photo gallery.
204 * Revamped command-line options of `sonar' and made it
205 properly handle subnets.
206 * The `bubbles' hack can now trickle up or down the
208 * The `xsublim' hack can now read its text from programs.
209 * Support for GLE version 3 in `extrusion'.
210 * Fixed compilation problems in `maze'.
211 * Fixed a rare crash in `flow'.
212 * Fixes for minor installation problems.
213 Changes since 3.23: * Added `-ignorant' option to `maze' hack.
214 * Updates to `critical', `bsod', `xflame', and `flow'.
215 * Added support for Kerberos 5 (via its Kerberos 4
216 compatibility layer.)
217 * Fixed a bad leak in `xteevee'.
218 * Updated `webcollage' to handle recent Altavista URL
220 * Removed xscreensaver-demo's `Ok' and `Cancel' buttons,
221 since they were confusing people: all changes are now
223 * Made xscreensaver-demo install itself into the Gnome
225 Changes since 3.22: * Fixed some misplaced text fields in the Motif version
226 of xscreensaver-demo; fixed a crash in the Gtk version
227 that would happen if the programs list was empty.
228 * Fixed a recently-introduced bug in `pulsar'.
229 * Made `sierpinski3d' use solid tetrahedrons instead of
231 * Added `-trace' option to `xmatrix'.
232 * Added new hacks `xteevee' and `xspirograph'.
233 Changes since 3.21: * Fixed some bugs in xscreensaver-demo.
234 * Rewrote the Motif version of xscreensaver-demo to
235 match the new Gtk version.
236 * The Athena toolkit is no longer supported.
237 Changes since 3.20: * Tweaked the xscreensaver-demo UI (Gtk only.)
238 * Fixed a few visual selection bugs. I think the proper
239 GL visual should be used with nVidia systems now.
240 * Made the Makefiles obey $install_prefix.
241 * Made the `xscreensaver.spec' file able to generate both
242 GL and non-GL packages simultaneously.
243 Changes since 3.19: * Added new hacks `ripples' and `sierpinski3d'.
244 * Made `xscreensaver-command -exit' be silent when no
245 screen saver was running (instead of complaining.)
246 * Made `webcollage' and `vidwhacker' use `xloadimage'
247 when available (in addition to `xli' and `xv'.)
248 * Improved memory usage in `petri' and gave it a hard
249 cap on how much memory it can allocate.
250 * Added `-watch' option to `xscreensaver-command'.
251 * Made `xscreensaver-demo' come up with the
252 most-recently-run hack selected by default.
253 * Rewrote the Gtk version of `xscreensaver-demo'.
254 It's a lot easier to use now.
255 * Extended the format of the programs list in the
256 .xscreensaver file, for the benefit of the new
257 capabilities of `xscreensaver-demo'.
258 NOTE: you might want to delete your ~/.xscreensaver
259 file and allow it to be re-created! The old one
260 should still work, but xscreensaver-demo won't be as
262 Changes since 3.18: * Fixed gcc dependencies in `bumps' and `ccurve'.
263 * New hack, `extrusion'.
264 * Some of the web sites that `webcollage' was using as
265 its sources changed formats; tweaked it to understand
267 * Added typeahead in the password dialog: if the screen
268 is locked, and you unlock it by typing a character,
269 that key will be automatically inserted in the
270 password dialog (unless it is Return, Enter, Space,
271 or a non-printing key like Shift.)
272 * Made `xmatrix' take a `-small' option, since some
273 folks with tiny screens prefer a smaller font.
274 Changes since 3.17: * New versions of `shadebobs', `lmorph', and `distort'.
275 * Added `ccurve', `blaster', and `bumps' hacks.
276 * Replaced `forest' hack with a rewritten version.
277 * Worked around a Xinerama server bug.
278 * Fixed a bug I introduced in 3.10 that caused some
279 hacks to print out superfluous warnings about not
280 having gotten enough colors.
281 * Made `sproingies' obey the `-delay' option.
282 * Fixed a portability bug in `shadebobs'.
283 * Made `webcollage' and `vidwhacker' use `xli' in
284 preference to `xv', if it is available.
285 * Added a new source of images to `webcollage'.
286 * If running under KDE, xscreensaver will add itself to
287 KDE's list of screensavers (via xscreensaver.kss.)
288 * Improved detection of GL libraries.
289 * Made the password dialog include the date and time.
290 Changes since 3.16: * New version of `webcollage' -- deals better with
291 corrupted images, and can use an http proxy.
292 * New hack, `xsublim' (run it in the background,
293 rather than adding it to the programs list.)
294 * The xscreensaver daemon was leaking a file descriptor
295 each time you edited your .xscreensaver file. Fixed.
296 Changes since 3.15: * New version of `shadebobs'.
297 * Improved image selection in `webcollage', and sped it
299 * Made configure find the right version of perl.
300 * Rewrote the CGI part of `webcollage'.
301 * `make clean' was deleting some things it shouldn't.
302 * Fixed a typo in the default programs list.
303 Changes since 3.14: * Added `webcollage' and `shadebobs' hacks.
304 * Added a `-stdout' arg to `vidwhacker' so that it can
305 be used in a pipeline.
306 * Made `petri' use less memory.
307 Changes since 3.13: * Various improvements to the Gtk port.
308 * Turned off PAM by default on Solaris, since PAM seems
309 generally to be misconfigured out-of-the-box.
310 * Made the `--without-gtk' configure option work.
311 * Made configure check the Gtk version number, since it
313 * Fixed a bug in the code that attempted to prevent
314 changes of screen resolution while the screen is
316 * Fixed a race condition in `xscreensaver-demo' that
317 could cause an X error at startup.
318 * Added `-transparent' option to `deluxe'.
319 * Added `petri' hack.
320 Changes since 3.12: * Ported `xscreensaver-demo' to Gtk.
321 * Made it possible to build Motif, Gtk, and Athena
322 versions of `xscreensaver-demo' in the same directory
323 without reconfiguring.
324 * Made `xscreensaver-demo' chase symlinks before writing
325 the .xscreensaver file, so that if .xscreensaver is
326 itself a symlink, the underlying file will be replaced
328 * Some Makefile and configure tweaks for Solaris and
330 * Made it possible to set the fire color in `xflame'.
331 * Made transparency work in TrueColor (for `goop' and
333 * Fixed a multi-head bug introduced by the virtual
335 Changes since 3.11: * Made it so that you can't scroll the screen while the
336 lock dialog is up (with XFree86 virtual viewports.)
337 * Fixed a bug in `flag' that caused bob's chin to get cut
338 off after a few iterations.
339 Changes since 3.10: * Made `xjack' be black-on-white-ish, so that it looks
340 less like a computer screen and more like the
341 typewritten paper it's supposed to be.
342 * New version of `pulsar'.
343 * Fixed Solaris compilation problem in `phosphor'.
344 * Made xscreensaver notice XFree86's virtual root window
345 hack, so that if the X server's root window is larger
346 than the monitor's displayable resolution, the screen
347 saver will limit itself to the area that actually
348 appears on the screen.
349 * Made the xscreensaver daemon do a better job of
350 picking the visual class that should be used for GL
351 programs. Less user intervention should be needed
352 now: you can use the logical visual name `GL' instead
353 of having to figure out by hand which one to use.
354 * Oops, the visual was defaulting to "best" instead of
355 "default", because the .xscreensaver file was not being
356 loaded quite early enough.
357 * Made configure figure out how to build icmp ping
358 support into the `sonar' hack automatically.
359 * Made warnings about not being able to read shadow
360 passwords not be printed if compiled with PAM support.
361 * Improved PAM startup diagnostics.
362 * Worked around the Solaris PAM bug that was causing
363 crashes there, so now PAM is turned on by default.
364 * Made configure detect the number of arguments that
365 pam_strerror() takes, since on Linux, this apparently
366 changed between 2.0 and 2.2, sigh.
367 * Made the /proc/interrupts kludge look for "PS/2 Mouse"
368 as well as "keyboard".
369 * Made xscreensaver notice when there has been a sudden
370 large jump in wall-clock time, and if so, lock right
371 away, instead of waiting for "lockTimeout" to expire
372 first. (Laptops need this for safer recovery from
374 * Added `-throttle' option to `xscreensaver-command'.
375 Changes since 3.09: * Added `phosphor', `xmatrix', and `pulsar' hacks.
376 * Fixed a bug in the color allocator that sometimes
377 caused `starfish' to fall back to monochrome.
378 * Reduced the amount of code that runs before root
379 privileges are disavowed: "normal" and "shadow"
380 passwords now do some initialization as root, but the
381 PAM and Kerberos authorization schemes will be
382 initialized while running as "nobody". Supposedly
383 this closes a potential security hole when using
385 * Added some more sanity checking to configure.
386 Changes since 3.08: * Added `compass', `squiral', `xflame', `wander',
387 `spotlight', and `critical' hacks.
388 * Added some new modes to `decayscreen'.
389 * Made `deluxe' work in monochrome.
390 * Generalized usage of the Double-Buffer server extension
391 in several hacks (`compass', `deluxe', `interference',
392 `kumppa', and `moire2'.)
393 * Fixed another visual-depth problem in `rd-bomb'.
394 * The screen saver will now defer blanking if neither
395 the keyboard nor the mouse could be grabbed. Instead,
396 it will just try again in a few minutes. This fixes
397 a bad interaction between xscreensaver and programs
398 like VMware that hold the mouse and keyboard grabbed
400 * Added a new erase mode (expanding spiral.)
401 Changes since 3.07: * Fixed some bugs in my port of `t3d'.
402 * Added `penetrate' and `deluxe' hacks.
403 * When linking against Motif 2.x, also link against XPM.
404 * Added support for using /proc/interrupts for idle
405 detection on Linux. Now xscreensaver shouldn't kick
406 in when the user is active on a non-X virtual console.
407 * Upgraded to autoconf 2.13.
408 Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
409 in properly; check for _Xsetlocale in -lXintl.)
410 * Portability fixes for sonar.c.
411 * Fixed a compilation problem when you have GL but don't
413 * Made configure notice when MesaGL requires -lpthread.
414 * Made `flame' ignore SIGFPE (not sure if this is the
415 right fix; it seems only to be needed on FreeBSD.)
416 * Kludged `rd-bomb' work on visuals that are of depth 24
417 but that *do not* support pixmaps of depth 32.
418 * Fixed `halo' to work properly in TrueColor.
419 * Changed `xscreensaver.spec' to install the hacks in
420 /usr/X11R6/lib/xscreensaver/ by default, since that's
421 where recent Red Hat distributions put them.
423 * Updated versions of `crystal', `hopalong', and `flow'
425 * Imported `demon' and `loop' modes from xlockmore.
426 Changes since 3.05: * Oops, the "default-n" visual descriptor was broken;
427 it was always installing a colormap if the
428 `installColormap' preference was set, meaning that
429 `xearth', `xv' and friends were using the wrong
430 colors on 8-bit systems.
431 * Turned off HAVE_PING in `sonar', since it compiles
432 on some Linux systems, but not others of similar
434 Changes since 3.04: * Fixed an off-by-1 in `distort'.
435 * Added `sonar' hack.
436 * New version of `glplanet' (with stars.)
437 * Made all hacks exit when you type `q' or `ESC' at them,
438 and made them obey the WM_DELETE_WINDOW ClientMessage.
439 * Fixed a nonfatal buffer overrun in lament (note:
440 lament still doesn't work with MesaGL 3.0: it dies in
441 lambda_textured_triangle1(), which is Mesa's bug, not
443 Changes since 3.03: * Added an `xscreensaver.spec' file, to make it easier
444 for other folks to generate RPMs.
445 * Made the password code work on HPUX in the situation
446 where: ``enhanced security'' is available; but not
447 used; but the user typed a password more than 8
448 characters long anyway. FTSOHPUX.
449 Changes since 3.02: * Made locking work when passwd aging is enabled.
450 * Added support for PAM (Pluggable Authentication
451 Modules.) It is still turned off by default, though,
452 since it doesn't seem to work on Solaris 2.6, and has
453 been behaving erratically on Red Hat 5.1.
454 * Made each possible authentication method be tried in
455 turn until one succeeds; this means that Kerberos is
456 being used, we will first check Kerberos, and if that
457 fails, will then consult the local password file.
459 * Save and restore the bits under the passwd dialog,
460 to avoid leaving a black rectangle behind when
461 unlocking is cancelled.
462 Changes since 3.01: * Not everyone has sys/select.h, sigh...
463 Changes since 3.00: * Some fixes to `reflect'.
465 * Made it log unsuccessful attempts to unlock the screen
467 * Fixed a bug where `xscreensaver-demo' could be seeing
468 a different programs list than `xscreensaver' did.
469 Changes since 2.34: * The xscreensaver daemon no longer links against Motif
470 or Athena: demo-mode and the preferences panel are no
471 longer built in to the daemon, but are now handled by
472 an external program, `xscreensaver-demo'.
473 (I decided that this, along with the recent addition
474 of the `.xscreensaver' config file, justified bumping
475 the version number to 3.00, since this is a fairly
476 major architectural change.)
477 * Lines in the `*programs' resource may now begin with
478 the character "-", meaning "don't run this hack."
479 In this way, it's possible to disable a hack without
480 throwing away the information about it (making it
481 easier to change your mind later.) Eventually the
482 preferences/demo mode GUI should represent this as a
483 checkbox or something.
484 * Fixed a short race condition where it was possible for
485 xscreensaver to die with a BadWindow error if it was
486 blanking the screen just as another window was being
488 * Made it possible to disable specific modes in `bsod'.
489 Changes since 2.33: * Fixed a bug that was making `pipes' generate way too
490 many valves. Made the viewpoint in `pipes' be selected
491 randomly instead of always being -10 degrees.
492 * Fixed a bug in the XSHM code, in the case where the
493 server supports the XSHM extension but is not the same
494 machine as the client.
495 * Made `rd-bomb' default to taking up the whole screen.
496 * Made it not try to do fading/unfading if no PseudoColor
498 * Initial attempt at supporting VT-locking (doesn't work
500 * Eliminated the `captureStdout' resource; now
501 `captureStderr' controls both streams.
502 * Added `-capture-stderr' and `-no-capture-stderr'
503 command-line arguments.
504 * Added `glplanet' hack.
505 * When a hack is selected with `xscreensaver-command
506 -select', that hack will be used until further notice
507 (until the saver turns off, or another activation
509 Changes since 2.32: * Made `xscreensaver-command' print error messages:
510 the xscreensaver daemon now responds to ClientMessage
511 events by writing a response message on a window
512 property, instead of just writing to its stderr.
513 * Made the ~/.xscreensaver file be automatically reloaded
514 when the file date changes.
515 * The password dialog and splash screen no longer depend
516 on Motif or Athena. This should clear up a number of
517 focus problems, and is the first step on the path
518 toward moving all of the Motif/Athena/whatever code
519 out of the xscreensaver daemon, and into external
521 * Don't complain about LessTif 0.86 any more, since the
522 new password dialog makes that problem go away.
523 * Configure tweaks for Irix 6.5, SunOS 5.something.
524 * New `-reflect' option to `distort'.
525 Changes since 2.31: * Added reading and writing of a ~/.xscreensaver file,
526 so that the Preferences panel can save its settings.
527 * New version of `rubik'.
528 * Added `-select N' argument to `xscreensaver-command'.
529 * Oops, left out some of the `bubbles3d' files...
530 Changes since 2.30: * The cursor was invisible in the password dialog. Fixed.
531 * Made configure warn against MesaGL 2.6.
532 * Fixed X error at startup when using non-default visual.
533 * New version of `crystal', `ant', and `atlantis' from
535 * New hack, `bubble3d'.
536 * Added some new modes to `bsod'.
537 Changes since 2.29: * Changed the order in which -lSM and -lICE are linked
538 to be after Motif instead of before (Lesstif on Irix
540 Changes since 2.28: * Work around a bash bug in configure.
541 * Tweaked HPUX paths again. FTSOHPUX.
542 * Made configure recommend against LessTif 0.86, due
543 to a bug in that version that causes a security hole
544 in the screen locking code. LessTif 0.87 will fix it.
545 * Made all of the `--with' options to `configure' accept
546 a directory option as well (so that --with-motif=/FOO
547 will add -I/FOO/include -L/FOO/lib). I believe this is
548 the Configure Party Line of how do to such things.
549 * Fixed a bug where the mouse was left un-grabbed
550 after the first time the graphics hack was changed
551 (simplified all of the mouse-grabbing logic.)
552 * Maybe possibly perhaps made `vidwhacker' really not
553 leave stray xv windows around. This time for sure.
554 * Added a new erase mode (random dots fizzling out.)
555 * Added `-prefs' argument to `xscreensaver-command',
556 that brings up the Preferences dialog directly (it
557 seems that nobody ever noticed the `Preferences' button
558 on the Demo Mode dialog, maybe this will help.)
559 * Added a splash screen. Turn it off with *splash:false.
560 Changes since 2.27: * Better macsbug text in `bsod'.
561 * New version of `distort' with many new modes.
562 * Plugged a leak in `coral'.
563 * Tweaked configure for HPUX.
564 * Removed some compiler warnings.
565 * More consistent usage of stderr versus stdout.
566 * More diagnostics should an X error occur.
567 * Fixed a possible crash in SGI-specific unfading code.
568 Changes since 2.26: * Improved version of `distort'.
569 * Made `lament' compile against OpenGL 1.0 (though it
570 still requires 1.1 to work properly.)
571 * Updated my email address and home page.
572 Changes since 2.24: * Improved motion in `rd-bomb'.
573 * Added XSHM (shared memory extension) support to the
574 `distort', `interference', `moire', `rd-bomb', and
575 `swirl' hacks, which speeds them up a bit.
576 * Added `lament' hack.
577 Changes since 2.23: * Tweaked the order of the -L options again.
578 * Cleaned up configure's `--help' message.
579 * Added `kumppa' hack.
580 * Smarter maze-solving algorithm in `maze'.
581 * Took `xlyap' out of the default list of hacks, since
582 it's just incredibly buggy (and slow.) Maybe someday
583 someone will fix it...
584 * Added `distort' hack, but didn't add it to the default
585 list (yet) because it's still too slow.
586 * Made the Athena demo dialog look more like the Motif
587 version; it has a text-entry field now, too.
588 * Made the Athena password dialog echo asterisks, like
589 Motif does, instead of using a flyspeck font.
590 * Some random configure tweaks.
591 * Added a `timestamp' resource that makes the `-verbose'
592 messages include the time at which they were printed.
593 Changes since 2.22: * The fix for SGI's ``scheme'' nonsense broke things, and
594 let the user's "*background" resource show through.
595 Fixed it in a different way.
596 Changes since 2.21: * Added support for the DPMS server extension (Display
597 Power Management System.)
598 * Made configure advertize the `--enable-subdir' option a
599 little more, since that seemed to cause some people
600 stress. Also, made that directory be built into the
601 xscreensaver executable, as a hardcoded prefix to
602 $PATH. (Might help, shouldn't hurt.)
603 * Made configure prefer the two-arg gettimeofday to the
604 one-arg version, since AIX doesn't have any prototypes.
605 * Made it work with Xaw3d (the 3D Athena library.)
606 * Made `make install' create directories as necessary.
607 * New version of lmorph from Sverre.
608 * Added `crystal' and `discreet' hacks from xlockmore.
609 * Added a new mode to `bsod'.
610 Changes since 2.20: * Made `xscreensaver-command -time' use different words.
611 (It now describes the two states as "screen blanked
612 since..." and "screen non-blanked since..." instead of
613 "active since..." and "inactive since..." which a lot
614 of people interpreted as meaning the opposite of what
616 * Improved some error messages, in the hopes of making
617 the distinction between the xscreensaver and
618 xscreensaver-command programs more obvious.
619 * Rewrote (and reorganized) parts of the xscreensaver and
620 xscreensaver-command manual pages.
621 * Renamed xscreensaver's `-lock' command-line option to
622 be `-lock-mode', to avoid confusion with the `-lock'
623 option to xscreensaver-command, which does a totally
625 * Removed xscreensaver's `-demo' command-line option for
626 a similar reason; use `xscreensaver-command -demo'
628 * Disabled SGI's ``scheme'' nonsense in a better way than
629 fully-qualifying the background colors in every single
631 * Fixed some other minor cosmetic problems when *sgiMode
633 * Fixed an X error in `bsod -root' (how ironic...)
634 Changes since 2.19: * Fixed a bug that caused the mouse to sometimes not be
635 grabbed properly (meaning the window manager menu could
636 pop up over the demo-mode display.)
637 * Fixed a bug that made the stderr output sometimes get
639 * Fixed a bug that made the demo-mode scrollbar move too
641 * Protected against a possible buffer overflow.
642 * Made `vidwhacker' not leave stray xv windows around.
643 * New version of `ant' so that Bagley doesn't calve.
644 * Make configure on AIX get XShm from the right library.

646 Changes since 2.17: * Oops, atlantis wasn't being built by default. Fixed.
647 * Added `epicycle' hack.
648 * Added `interference' hack.
649 * Added `truchet' hack.
651 * Added some new modes to `vidwhacker'.
652 Changes since 2.16: * Added a -window-id argument to most hacks, so that they
653 can draw on arbitrary externally-provided windows.
654 * Synched with xlockmore 4.11a01.
656 * Added `atlantis' GL hack.
657 * Renamed `puzzle' hack to `jigsaw', since xlock already
658 had a different mode called `puzzle'.
659 * Made it self-configure properly when Motif 2.1.0 is
660 being used (requires -lXp now, sigh...)
661 Changes since 2.15: * Made `flag' able to do XPM images.
662 * New look for the xscreensaver logo (`xroger').
663 * Fixed compilation error on Suns with adjunct passwords.

675 * Split `escher' into `cage' and `moebius', as per
677 * Changed subprocess handling to use sigaction() instead
678 of signal() if it's available (this is necessary for
679 SCO but should work fine on other systems too.)
680 * Various other tweaks.
681 Changes since 2.13: * Better fix for the Motif drag-and-die lossage.
682 * Put in some kludges to work around a LessTif bug.
683 * XScreenSaver is known to work with LessTif 0.82 now.
684 * Made fading work on high-end SGI video hardware.
685 * Fixed another SGI-specific bug in screen grabbing;
686 will the madness never cease?
687 * Fixed another crash in `xlyap'.
688 Changes since 2.12: * Made `decayscreen' do directions other than down.
690 * Fixed a crash in `xlyap'.
691 * Added CDE info to the man page, removed `cde.txt'.
692 * Configure tweaks for Zippy.
693 * Turned off the signal handling in `bubbles' because
694 it was sometimes failing to die.

697 with xscreensaver. Finally!
698 * Fixed a buffer overrun in the locking code that some
699 wily, malicious cracker must have slipped in.
700 * Disabled Motif drag-and-drool in the dialog box
701 buttons, since it's broken in some old versions of

704 * Added `puzzle' hack.
705 * Added `xlyap' hack.
706 * Added `default-n' as a visual name, so that one can
707 have -install on by default, but turn it off for
708 certain poorly-behaved hacks (like xv.)
709 * Added support for grabbing frames of external video
710 (on SGI) to the screen-grabbing hacks (decayscreen,
711 slidescreen, slip, blitspin, and puzzle.)
712 * Improved look of tiles in `slidescreen'; fixed its
713 color allocation problem.
714 Changes since 2.10: * Tweaked `blitspin', added it to the default list.
715 * Added `lissie', `mountain', `triangle', `worm',
716 `rotor', and `ant' from xlockmore.
717 * Updated `sierpinski', `galaxy', and `lisa'.

790 themselves: it now re-blanks the screen every so often.
791 * Added `-time' option to `xscreensaver-command'.
792 * Improved SGI screen-grabbing some more: now it can grab
