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 3.33: * Turned `memoryLimit' off by default, sigh. Apparently
75 some versions of the GL libraries (appear to) allocate
76 hundreds of megs for every GL program, so `memoryLimit'
77 was causing GL programs to malfunction or crash on
79 * Improved fading on TrueColor XFree86 4.1.x systems.
80 * New GL hack, `circuit'.
81 * Added `fuzz' mode to `decayscreen'.
82 * New version of `whirlygig'.
83 * Added links to `glplanet' and `sphereEversion'.
84 * Fixed rare race condition that could make `sonar' hang.
85 * Fixed potential crash in `speedmine'.
86 * Made `xscreensaver-demo' not crash when imageDirectory
87 was set to a non-existent directory.
88 * Made `xscreensaver-getimage-video' invoke XawTV's
89 `streamer' program better.
90 * Made `phosphor' and `starwars' deal with CR, LF,
92 * Changes for Cygwin compilation environments.
93 * Made `sonar' compile on systems that can't ping.
94 * Configure changes for HPUX 10.20.
95 * Made PAM code work on Red Had 4.2 systems.
96 * Made `xscreensaver-command -deactivate' work when the
97 saver is not active: what that does is reset the idle
98 timer, as if keyboard input had been detected. This
99 was added for the benefit of people writing DVD-playing
100 software: they can now prevent the screensaver from
101 kicking in by sending a -deactivate message once a
102 minute while the movie is playing and not paused.
103 * Various minor portability tweaks.
104 Changes since 3.32: * New hacks, `speedmine' and `whirlygig'.
105 * Sped up `pyro', made the explosions look a bit better.
106 * Added better stars to `glplanet' and `starwars'.
107 * Many internal changes to `webcollage'.
108 * Some new options to `attraction'.
109 * Minor fix to `noseguy' to avoid un-erased pixels.
110 * Rewrote the screen-eraser effects so that they complete
111 in the same amount of time regardless of how slow
112 your X server is (some of them were glacial on servers
114 * Fixed a potential free memory reference that could
115 sometimes cause a crash at startup.
116 * Possibly fixed a problem that could cause the daemon
117 to crash with an X error. I was never able to
118 reproduce this problem, but I think I might have
119 figured out what caused it.
120 * Worked around a problem that caused PAM authentication
121 to fail on some Red Hat 7.x systems.
122 * Added a `memoryLimit' parameter that controls the
123 amount of memory a graphics hack may allocate: if they
124 try to allocate more than this, malloc() will fail
125 (and they will exit or (safely) crash, rather than
126 hogging memory.) Default is 50M.
127 * Made `gnome-help-browser' be the default way to display
128 man pages in `xscreensaver-demo', if running on a
130 Changes since 3.31: * The image-manipulating hacks (`slidescreen', etc.) can
131 now operate on randomly chosen image files from disk,
132 or on frames captured from the system's video input,
133 instead of (or in addition to) manipulating images of
135 * Rewrote `vidwhacker' to use the new image-grabbing
137 * Made fading work on TrueColor XFree86 4.x systems.
138 * Fixed a subtle rendering bug in `atlantis' (the fish
140 * Made `atlantis' have a texture simulating light
141 reflections from the surface of the ocean.
142 * Fixed up label placement in `molecule'.
143 * Better color bars in `xteevee'.
144 * Made `install-strip' not try to strip scripts.
145 Changes since 3.30: * Put in more sensible defaults for DPMS, and updated
146 the documentation to reflect the fact that all your
147 DPMS settings are now belong to xscreensaver.
148 * Fixed the `xscreensaver.spec' file so that `--force'
150 * New versions of `rotzoomer' and `nerverot'.
151 * Fixed an OSF/1 compilation problem in `molecule'.
152 Changes since 3.29: * New hacks, `molecule' `dangerball', and `rotzoomer'.
153 * New version of `gflux'.
154 * Made `gltext' able to display the current time.
155 * Fixed a floating-point-precision problem in `gltext'
156 that sometimes caused horizontal lines to vanish.
157 * Removed the `-window-id' option from the hacks:
158 it never worked right, and was unnecessary.
159 * Made the `starwars' hack use thicker lines, antialias
160 the text, and fade out at the far edge instead of just
162 * Fixed an SHM segment leak in `moire'.
163 Changes since 3.28: * Better rendering of the new logo.
164 * New hack, `gltext'.
165 * Added `-planetary' option to `gears', to draw a
166 different kind of gear system.
167 * Made motion and rotation be smoother in `gears',
168 `glplanet', `moebius', `rubik', and `sierpinski3d'.
169 * Improved coloration in `sierpinski3d'.
170 * Made the GL hacks react to window size changes.
171 * Made most of the GL hacks take a -fps option (like
172 `pulsar' did), so you can use them to benchmark your
174 * Fixed the previous fix to `sonar'.
175 * Minor fix to `nerverot'.
176 Made sonar able to ping hosts on DEC OSF1.
177 * Eliminated a bogus "didn't get enough colors" warning
178 in some of the hacks.
179 Changes since 3.27: * New logo for xscreensaver!
180 * New hacks, `starwars' and `stonerview'.
181 * Made the motion of the bouncing ball in `stairs' be a
183 * Made newly-added screenhacks be added to .xscreensaver
184 automatically: if there are hacks in the app-defaults
185 file that are not also in ~/.xscreensaver, they will
186 be added to the end of the list.
187 * Redid the `Screensaver Options' part of the control
188 panel; xscreensaver now lets you configure your DPMS
190 * Fixed some Makefile problems with non-GL builds.
191 * Fixed detection of MesaGL for version 3.3.
192 * Better workaround to Red Hat 7.0's broken gcc.
193 * Added Sparc Solaris kernel panic to `bsod'.
194 Changes since 3.26: * New hacks: `zoom' and `whirlwindwarp'.
195 * Fixed a free-memory-reference bug in `sonar'.
196 * Better error handling when there are no suitable GL
198 * Added diagnostic dialog when xscreensaver-demo is
199 unable to launch xscreensaver (e.g., when running as
201 * Fixed a bug that caused screenhack argument changes
202 to be ignored when xscreensaver-demo was running as
203 root (if "root" and "nobody" have different home
205 * Made the programs default to ":0" if $DISPLAY is unset.
206 * Made the `-verbose' output include information about
207 which server extensions were supported at compile time.
208 * Worked around Red Hat 7.0's broken gcc 2.96.
209 * Updated default delays on the GL hacks to look better
210 on machines with super-fast 3D hardware.
211 * Install `screensaver-properties-capplet' to work around
212 the usual egregious GNOME lossage.
213 Changes since 3.25: * Added "enabled" checkboxes in the list of hacks in
214 xscreensaver-demo (Gtk version only.)
215 * New hacks `hyperball', `xrayswarm', and `gflux'.
216 * New versions of `nerverot', `galaxy', and `hypercube'.
217 * Small fixes to `phosphor', `shadebobs', `xflame',
219 * Added external helper program `xscreensaver-gl-helper'
220 to figure out which X visual to use for OpenGL
222 * Configure updates for XFree86 4.0, and for BSD.
223 * Made it be more tolerant of bogus /etc/group files.
224 * When installing the PAM config file, first try to just
225 copy an existing "xdm" or "login" config file, so that
226 xscreensaver does authentication in the same way as the
228 Changes since 3.24: * New hack, `nerverot'.
229 * Added BSD kernel panic to `bsod'.
230 * New version of `shadebobs'.
231 * New version of `petri'.
232 * Updated `webcollage' to handle recent Altavista URL
233 format changes; made it search the AP photo gallery.
234 * Revamped command-line options of `sonar' and made it
235 properly handle subnets.
236 * The `bubbles' hack can now trickle up or down the
238 * The `xsublim' hack can now read its text from programs.
239 * Support for GLE version 3 in `extrusion'.
240 * Fixed compilation problems in `maze'.
241 * Fixed a rare crash in `flow'.
242 * Fixes for minor installation problems.
243 Changes since 3.23: * Added `-ignorant' option to `maze' hack.
244 * Updates to `critical', `bsod', `xflame', and `flow'.
245 * Added support for Kerberos 5 (via its Kerberos 4
246 compatibility layer.)
247 * Fixed a bad leak in `xteevee'.
248 * Updated `webcollage' to handle recent Altavista URL
250 * Removed xscreensaver-demo's `Ok' and `Cancel' buttons,
251 since they were confusing people: all changes are now
253 * Made xscreensaver-demo install itself into the Gnome
255 Changes since 3.22: * Fixed some misplaced text fields in the Motif version
256 of xscreensaver-demo; fixed a crash in the Gtk version
257 that would happen if the programs list was empty.
258 * Fixed a recently-introduced bug in `pulsar'.
259 * Made `sierpinski3d' use solid tetrahedrons instead of
261 * Added `-trace' option to `xmatrix'.
262 * Added new hacks `xteevee' and `xspirograph'.
263 Changes since 3.21: * Fixed some bugs in xscreensaver-demo.
264 * Rewrote the Motif version of xscreensaver-demo to
265 match the new Gtk version.
266 * The Athena toolkit is no longer supported.
267 Changes since 3.20: * Tweaked the xscreensaver-demo UI (Gtk only.)
268 * Fixed a few visual selection bugs. I think the proper
269 GL visual should be used with nVidia systems now.
270 * Made the Makefiles obey $install_prefix.
271 * Made the `xscreensaver.spec' file able to generate both
272 GL and non-GL packages simultaneously.
273 Changes since 3.19: * Added new hacks `ripples' and `sierpinski3d'.
274 * Made `xscreensaver-command -exit' be silent when no
275 screen saver was running (instead of complaining.)
276 * Made `webcollage' and `vidwhacker' use `xloadimage'
277 when available (in addition to `xli' and `xv'.)
278 * Improved memory usage in `petri' and gave it a hard
279 cap on how much memory it can allocate.
280 * Added `-watch' option to `xscreensaver-command'.
281 * Made `xscreensaver-demo' come up with the
282 most-recently-run hack selected by default.
283 * Rewrote the Gtk version of `xscreensaver-demo'.
284 It's a lot easier to use now.
285 * Extended the format of the programs list in the
286 .xscreensaver file, for the benefit of the new
287 capabilities of `xscreensaver-demo'.
288 NOTE: you might want to delete your ~/.xscreensaver
289 file and allow it to be re-created! The old one
290 should still work, but xscreensaver-demo won't be as
292 Changes since 3.18: * Fixed gcc dependencies in `bumps' and `ccurve'.
293 * New hack, `extrusion'.
294 * Some of the web sites that `webcollage' was using as
295 its sources changed formats; tweaked it to understand
297 * Added typeahead in the password dialog: if the screen
298 is locked, and you unlock it by typing a character,
299 that key will be automatically inserted in the
300 password dialog (unless it is Return, Enter, Space,
301 or a non-printing key like Shift.)
302 * Made `xmatrix' take a `-small' option, since some
303 folks with tiny screens prefer a smaller font.
304 Changes since 3.17: * New versions of `shadebobs', `lmorph', and `distort'.
305 * Added `ccurve', `blaster', and `bumps' hacks.
306 * Replaced `forest' hack with a rewritten version.
307 * Worked around a Xinerama server bug.
308 * Fixed a bug I introduced in 3.10 that caused some
309 hacks to print out superfluous warnings about not
310 having gotten enough colors.
311 * Made `sproingies' obey the `-delay' option.
312 * Fixed a portability bug in `shadebobs'.
313 * Made `webcollage' and `vidwhacker' use `xli' in
314 preference to `xv', if it is available.
315 * Added a new source of images to `webcollage'.
316 * If running under KDE, xscreensaver will add itself to
317 KDE's list of screensavers (via xscreensaver.kss.)
318 * Improved detection of GL libraries.
319 * Made the password dialog include the date and time.
320 Changes since 3.16: * New version of `webcollage' -- deals better with
321 corrupted images, and can use an http proxy.
322 * New hack, `xsublim' (run it in the background,
323 rather than adding it to the programs list.)
324 * The xscreensaver daemon was leaking a file descriptor
325 each time you edited your .xscreensaver file. Fixed.
326 Changes since 3.15: * New version of `shadebobs'.
327 * Improved image selection in `webcollage', and sped it
329 * Made configure find the right version of perl.
330 * Rewrote the CGI part of `webcollage'.
331 * `make clean' was deleting some things it shouldn't.
332 * Fixed a typo in the default programs list.
333 Changes since 3.14: * Added `webcollage' and `shadebobs' hacks.
334 * Added a `-stdout' arg to `vidwhacker' so that it can
335 be used in a pipeline.
336 * Made `petri' use less memory.
337 Changes since 3.13: * Various improvements to the Gtk port.
338 * Turned off PAM by default on Solaris, since PAM seems
339 generally to be misconfigured out-of-the-box.
340 * Made the `--without-gtk' configure option work.
341 * Made configure check the Gtk version number, since it
343 * Fixed a bug in the code that attempted to prevent
344 changes of screen resolution while the screen is
346 * Fixed a race condition in `xscreensaver-demo' that
347 could cause an X error at startup.
348 * Added `-transparent' option to `deluxe'.
349 * Added `petri' hack.
350 Changes since 3.12: * Ported `xscreensaver-demo' to Gtk.
351 * Made it possible to build Motif, Gtk, and Athena
352 versions of `xscreensaver-demo' in the same directory
353 without reconfiguring.
354 * Made `xscreensaver-demo' chase symlinks before writing
355 the .xscreensaver file, so that if .xscreensaver is
356 itself a symlink, the underlying file will be replaced
358 * Some Makefile and configure tweaks for Solaris and
360 * Made it possible to set the fire color in `xflame'.
361 * Made transparency work in TrueColor (for `goop' and
363 * Fixed a multi-head bug introduced by the virtual
365 Changes since 3.11: * Made it so that you can't scroll the screen while the
366 lock dialog is up (with XFree86 virtual viewports.)
367 * Fixed a bug in `flag' that caused bob's chin to get cut
368 off after a few iterations.
369 Changes since 3.10: * Made `xjack' be black-on-white-ish, so that it looks
370 less like a computer screen and more like the
371 typewritten paper it's supposed to be.
372 * New version of `pulsar'.
373 * Fixed Solaris compilation problem in `phosphor'.
374 * Made xscreensaver notice XFree86's virtual root window
375 hack, so that if the X server's root window is larger
376 than the monitor's displayable resolution, the screen
377 saver will limit itself to the area that actually
378 appears on the screen.
379 * Made the xscreensaver daemon do a better job of
380 picking the visual class that should be used for GL
381 programs. Less user intervention should be needed
382 now: you can use the logical visual name `GL' instead
383 of having to figure out by hand which one to use.
384 * Oops, the visual was defaulting to "best" instead of
385 "default", because the .xscreensaver file was not being
386 loaded quite early enough.
387 * Made configure figure out how to build icmp ping
388 support into the `sonar' hack automatically.
389 * Made warnings about not being able to read shadow
390 passwords not be printed if compiled with PAM support.
391 * Improved PAM startup diagnostics.
392 * Worked around the Solaris PAM bug that was causing
393 crashes there, so now PAM is turned on by default.
394 * Made configure detect the number of arguments that
395 pam_strerror() takes, since on Linux, this apparently
396 changed between 2.0 and 2.2, sigh.
397 * Made the /proc/interrupts kludge look for "PS/2 Mouse"
398 as well as "keyboard".
399 * Made xscreensaver notice when there has been a sudden
400 large jump in wall-clock time, and if so, lock right
401 away, instead of waiting for "lockTimeout" to expire
402 first. (Laptops need this for safer recovery from
404 * Added `-throttle' option to `xscreensaver-command'.
405 Changes since 3.09: * Added `phosphor', `xmatrix', and `pulsar' hacks.
406 * Fixed a bug in the color allocator that sometimes
407 caused `starfish' to fall back to monochrome.
408 * Reduced the amount of code that runs before root
409 privileges are disavowed: "normal" and "shadow"
410 passwords now do some initialization as root, but the
411 PAM and Kerberos authorization schemes will be
412 initialized while running as "nobody". Supposedly
413 this closes a potential security hole when using
415 * Added some more sanity checking to configure.
416 Changes since 3.08: * Added `compass', `squiral', `xflame', `wander',
417 `spotlight', and `critical' hacks.
418 * Added some new modes to `decayscreen'.
419 * Made `deluxe' work in monochrome.
420 * Generalized usage of the Double-Buffer server extension
421 in several hacks (`compass', `deluxe', `interference',
422 `kumppa', and `moire2'.)
423 * Fixed another visual-depth problem in `rd-bomb'.
424 * The screen saver will now defer blanking if neither
425 the keyboard nor the mouse could be grabbed. Instead,
426 it will just try again in a few minutes. This fixes
427 a bad interaction between xscreensaver and programs
428 like VMware that hold the mouse and keyboard grabbed
430 * Added a new erase mode (expanding spiral.)
431 Changes since 3.07: * Fixed some bugs in my port of `t3d'.
432 * Added `penetrate' and `deluxe' hacks.
433 * When linking against Motif 2.x, also link against XPM.
434 * Added support for using /proc/interrupts for idle
435 detection on Linux. Now xscreensaver shouldn't kick
436 in when the user is active on a non-X virtual console.
437 * Upgraded to autoconf 2.13.
438 Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
439 in properly; check for _Xsetlocale in -lXintl.)
440 * Portability fixes for sonar.c.
441 * Fixed a compilation problem when you have GL but don't
443 * Made configure notice when MesaGL requires -lpthread.
444 * Made `flame' ignore SIGFPE (not sure if this is the
445 right fix; it seems only to be needed on FreeBSD.)
446 * Kludged `rd-bomb' work on visuals that are of depth 24
447 but that *do not* support pixmaps of depth 32.
448 * Fixed `halo' to work properly in TrueColor.
449 * Changed `xscreensaver.spec' to install the hacks in
450 /usr/X11R6/lib/xscreensaver/ by default, since that's
451 where recent Red Hat distributions put them.
453 * Updated versions of `crystal', `hopalong', and `flow'
455 * Imported `demon' and `loop' modes from xlockmore.
456 Changes since 3.05: * Oops, the "default-n" visual descriptor was broken;
457 it was always installing a colormap if the
458 `installColormap' preference was set, meaning that
459 `xearth', `xv' and friends were using the wrong
460 colors on 8-bit systems.
461 * Turned off HAVE_PING in `sonar', since it compiles
462 on some Linux systems, but not others of similar
464 Changes since 3.04: * Fixed an off-by-1 in `distort'.
465 * Added `sonar' hack.
466 * New version of `glplanet' (with stars.)
467 * Made all hacks exit when you type `q' or `ESC' at them,
468 and made them obey the WM_DELETE_WINDOW ClientMessage.
469 * Fixed a nonfatal buffer overrun in lament (note:
470 lament still doesn't work with MesaGL 3.0: it dies in
471 lambda_textured_triangle1(), which is Mesa's bug, not
473 Changes since 3.03: * Added an `xscreensaver.spec' file, to make it easier
474 for other folks to generate RPMs.
475 * Made the password code work on HPUX in the situation
476 where: ``enhanced security'' is available; but not
477 used; but the user typed a password more than 8
478 characters long anyway. FTSOHPUX.
479 Changes since 3.02: * Made locking work when passwd aging is enabled.
480 * Added support for PAM (Pluggable Authentication
481 Modules.) It is still turned off by default, though,
482 since it doesn't seem to work on Solaris 2.6, and has
483 been behaving erratically on Red Hat 5.1.
484 * Made each possible authentication method be tried in
485 turn until one succeeds; this means that Kerberos is
486 being used, we will first check Kerberos, and if that
487 fails, will then consult the local password file.
489 * Save and restore the bits under the passwd dialog,
490 to avoid leaving a black rectangle behind when
491 unlocking is cancelled.
492 Changes since 3.01: * Not everyone has sys/select.h, sigh...
493 Changes since 3.00: * Some fixes to `reflect'.
495 * Made it log unsuccessful attempts to unlock the screen
497 * Fixed a bug where `xscreensaver-demo' could be seeing
498 a different programs list than `xscreensaver' did.
499 Changes since 2.34: * The xscreensaver daemon no longer links against Motif
500 or Athena: demo-mode and the preferences panel are no
501 longer built in to the daemon, but are now handled by
502 an external program, `xscreensaver-demo'.
503 (I decided that this, along with the recent addition
504 of the `.xscreensaver' config file, justified bumping
505 the version number to 3.00, since this is a fairly
506 major architectural change.)
507 * Lines in the `*programs' resource may now begin with
508 the character "-", meaning "don't run this hack."
509 In this way, it's possible to disable a hack without
510 throwing away the information about it (making it
511 easier to change your mind later.) Eventually the
512 preferences/demo mode GUI should represent this as a
513 checkbox or something.
514 * Fixed a short race condition where it was possible for
515 xscreensaver to die with a BadWindow error if it was
516 blanking the screen just as another window was being
518 * Made it possible to disable specific modes in `bsod'.
519 Changes since 2.33: * Fixed a bug that was making `pipes' generate way too
520 many valves. Made the viewpoint in `pipes' be selected
521 randomly instead of always being -10 degrees.
522 * Fixed a bug in the XSHM code, in the case where the
523 server supports the XSHM extension but is not the same
524 machine as the client.
525 * Made `rd-bomb' default to taking up the whole screen.
526 * Made it not try to do fading/unfading if no PseudoColor
528 * Initial attempt at supporting VT-locking (doesn't work
530 * Eliminated the `captureStdout' resource; now
531 `captureStderr' controls both streams.
532 * Added `-capture-stderr' and `-no-capture-stderr'
533 command-line arguments.
534 * Added `glplanet' hack.
535 * When a hack is selected with `xscreensaver-command
536 -select', that hack will be used until further notice
537 (until the saver turns off, or another activation
539 Changes since 2.32: * Made `xscreensaver-command' print error messages:
540 the xscreensaver daemon now responds to ClientMessage
541 events by writing a response message on a window
542 property, instead of just writing to its stderr.
543 * Made the ~/.xscreensaver file be automatically reloaded
544 when the file date changes.
545 * The password dialog and splash screen no longer depend
546 on Motif or Athena. This should clear up a number of
547 focus problems, and is the first step on the path
548 toward moving all of the Motif/Athena/whatever code
549 out of the xscreensaver daemon, and into external
551 * Don't complain about LessTif 0.86 any more, since the
552 new password dialog makes that problem go away.
553 * Configure tweaks for Irix 6.5, SunOS 5.something.
554 * New `-reflect' option to `distort'.
555 Changes since 2.31: * Added reading and writing of a ~/.xscreensaver file,
556 so that the Preferences panel can save its settings.
557 * New version of `rubik'.
558 * Added `-select N' argument to `xscreensaver-command'.
559 * Oops, left out some of the `bubbles3d' files...
560 Changes since 2.30: * The cursor was invisible in the password dialog. Fixed.
561 * Made configure warn against MesaGL 2.6.
562 * Fixed X error at startup when using non-default visual.
563 * New version of `crystal', `ant', and `atlantis' from
565 * New hack, `bubble3d'.
566 * Added some new modes to `bsod'.
567 Changes since 2.29: * Changed the order in which -lSM and -lICE are linked
568 to be after Motif instead of before (Lesstif on Irix
570 Changes since 2.28: * Work around a bash bug in configure.
571 * Tweaked HPUX paths again. FTSOHPUX.
572 * Made configure recommend against LessTif 0.86, due
573 to a bug in that version that causes a security hole
574 in the screen locking code. LessTif 0.87 will fix it.
575 * Made all of the `--with' options to `configure' accept
576 a directory option as well (so that --with-motif=/FOO
577 will add -I/FOO/include -L/FOO/lib). I believe this is
578 the Configure Party Line of how do to such things.
579 * Fixed a bug where the mouse was left un-grabbed
580 after the first time the graphics hack was changed
581 (simplified all of the mouse-grabbing logic.)
582 * Maybe possibly perhaps made `vidwhacker' really not
583 leave stray xv windows around. This time for sure.
584 * Added a new erase mode (random dots fizzling out.)
585 * Added `-prefs' argument to `xscreensaver-command',
586 that brings up the Preferences dialog directly (it
587 seems that nobody ever noticed the `Preferences' button
588 on the Demo Mode dialog, maybe this will help.)
589 * Added a splash screen. Turn it off with *splash:false.
590 Changes since 2.27: * Better macsbug text in `bsod'.
591 * New version of `distort' with many new modes.
592 * Plugged a leak in `coral'.
593 * Tweaked configure for HPUX.
594 * Removed some compiler warnings.
595 * More consistent usage of stderr versus stdout.
596 * More diagnostics should an X error occur.
597 * Fixed a possible crash in SGI-specific unfading code.
598 Changes since 2.26: * Improved version of `distort'.
599 * Made `lament' compile against OpenGL 1.0 (though it
600 still requires 1.1 to work properly.)
601 * Updated my email address and home page.
602 Changes since 2.24: * Improved motion in `rd-bomb'.
603 * Added XSHM (shared memory extension) support to the
604 `distort', `interference', `moire', `rd-bomb', and
605 `swirl' hacks, which speeds them up a bit.
606 * Added `lament' hack.
607 Changes since 2.23: * Tweaked the order of the -L options again.
608 * Cleaned up configure's `--help' message.
609 * Added `kumppa' hack.
610 * Smarter maze-solving algorithm in `maze'.
611 * Took `xlyap' out of the default list of hacks, since
612 it's just incredibly buggy (and slow.) Maybe someday
613 someone will fix it...
614 * Added `distort' hack, but didn't add it to the default
615 list (yet) because it's still too slow.
616 * Made the Athena demo dialog look more like the Motif
617 version; it has a text-entry field now, too.
618 * Made the Athena password dialog echo asterisks, like
619 Motif does, instead of using a flyspeck font.
620 * Some random configure tweaks.
621 * Added a `timestamp' resource that makes the `-verbose'
622 messages include the time at which they were printed.
623 Changes since 2.22: * The fix for SGI's ``scheme'' nonsense broke things, and
624 let the user's "*background" resource show through.
625 Fixed it in a different way.
626 Changes since 2.21: * Added support for the DPMS server extension (Display
627 Power Management System.)
628 * Made configure advertize the `--enable-subdir' option a
629 little more, since that seemed to cause some people
630 stress. Also, made that directory be built into the
631 xscreensaver executable, as a hardcoded prefix to
632 $PATH. (Might help, shouldn't hurt.)
633 * Made configure prefer the two-arg gettimeofday to the
634 one-arg version, since AIX doesn't have any prototypes.
635 * Made it work with Xaw3d (the 3D Athena library.)
636 * Made `make install' create directories as necessary.
637 * New version of lmorph from Sverre.
638 * Added `crystal' and `discreet' hacks from xlockmore.
639 * Added a new mode to `bsod'.
640 Changes since 2.20: * Made `xscreensaver-command -time' use different words.
641 (It now describes the two states as "screen blanked
642 since..." and "screen non-blanked since..." instead of
643 "active since..." and "inactive since..." which a lot
644 of people interpreted as meaning the opposite of what
646 * Improved some error messages, in the hopes of making
647 the distinction between the xscreensaver and
648 xscreensaver-command programs more obvious.
649 * Rewrote (and reorganized) parts of the xscreensaver and
650 xscreensaver-command manual pages.
651 * Renamed xscreensaver's `-lock' command-line option to
652 be `-lock-mode', to avoid confusion with the `-lock'
653 option to xscreensaver-command, which does a totally
655 * Removed xscreensaver's `-demo' command-line option for
656 a similar reason; use `xscreensaver-command -demo'
658 * Disabled SGI's ``scheme'' nonsense in a better way than
659 fully-qualifying the background colors in every single
661 * Fixed some other minor cosmetic problems when *sgiMode
663 * Fixed an X error in `bsod -root' (how ironic...)
664 Changes since 2.19: * Fixed a bug that caused the mouse to sometimes not be
665 grabbed properly (meaning the window manager menu could
666 pop up over the demo-mode display.)
667 * Fixed a bug that made the stderr output sometimes get
669 * Fixed a bug that made the demo-mode scrollbar move too
671 * Protected against a possible buffer overflow.
672 * Made `vidwhacker' not leave stray xv windows around.
673 * New version of `ant' so that Bagley doesn't calve.
674 * Make configure on AIX get XShm from the right library.
675 Changes since 2.18: * One file was missing from the tar file. Fixed.
676 Changes since 2.17: * Oops, atlantis wasn't being built by default. Fixed.
677 * Added `epicycle' hack.
678 * Added `interference' hack.
679 * Added `truchet' hack.
681 * Added some new modes to `vidwhacker'.
682 Changes since 2.16: * Added a -window-id argument to most hacks, so that they
683 can draw on arbitrary externally-provided windows.
684 * Synched with xlockmore 4.11a01.
686 * Added `atlantis' GL hack.
687 * Renamed `puzzle' hack to `jigsaw', since xlock already
688 had a different mode called `puzzle'.
689 * Made it self-configure properly when Motif 2.1.0 is
690 being used (requires -lXp now, sigh...)
691 Changes since 2.15: * Made `flag' able to do XPM images.
692 * New look for the xscreensaver logo (`xroger').
693 * Fixed compilation error on Suns with adjunct passwords.

705 * Split `escher' into `cage' and `moebius', as per
707 * Changed subprocess handling to use sigaction() instead
708 of signal() if it's available (this is necessary for
709 SCO but should work fine on other systems too.)
710 * Various other tweaks.
711 Changes since 2.13: * Better fix for the Motif drag-and-die lossage.
712 * Put in some kludges to work around a LessTif bug.
713 * XScreenSaver is known to work with LessTif 0.82 now.
714 * Made fading work on high-end SGI video hardware.
715 * Fixed another SGI-specific bug in screen grabbing;
716 will the madness never cease?
717 * Fixed another crash in `xlyap'.
718 Changes since 2.12: * Made `decayscreen' do directions other than down.
720 * Fixed a crash in `xlyap'.
721 * Added CDE info to the man page, removed `cde.txt'.
722 * Configure tweaks for Zippy.
723 * Turned off the signal handling in `bubbles' because
724 it was sometimes failing to die.
725 * Added `hacks/xscreensaver-sgigl.c' to make it possible

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

734 * Added `puzzle' hack.
735 * Added `xlyap' hack.
736 * Added `default-n' as a visual name, so that one can
737 have -install on by default, but turn it off for
738 certain poorly-behaved hacks (like xv.)
739 * Added support for grabbing frames of external video
740 (on SGI) to the screen-grabbing hacks (decayscreen,
741 slidescreen, slip, blitspin, and puzzle.)
742 * Improved look of tiles in `slidescreen'; fixed its
743 color allocation problem.
744 Changes since 2.10: * Tweaked `blitspin', added it to the default list.
745 * Added `lissie', `mountain', `triangle', `worm',
746 `rotor', and `ant' from xlockmore.
747 * Updated `sierpinski', `galaxy', and `lisa'.
748 * Thickened the lines in `braid' and `lmorph'.

791 * Made the stderr text use overlay planes, if possible.
792 * Reworked the xlockmore compatibility stuff again.
793 * Added `gears', `superquadrics', `escher', `pipes',
794 and `sproingies' hacks (depend on OpenGL.)
795 Changes since 1.33: * Fixed some bugs, made fading be a little smoother.
796 Changes since 1.32: * Made it work with multi-headed displays.

819 the screen, or allowing other windows to raise
820 themselves: it now re-blanks the screen every so often.
821 * Added `-time' option to `xscreensaver-command'.
822 * Improved SGI screen-grabbing some more: now it can grab
823 TrueColor screens into PseudoColor windows and have the
824 colors still come out semi-reasonably.
825 Changes since 1.29: * Made `slidescreen' and `decayscreen' work better on
