4 a screen saver and locker for the X window system

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 3.31: * The image-manipulating hacks (`slidescreen', etc.) can
75 now operate on randomly chosen image files from disk,
76 or on frames captured from the system's video input,
77 instead of (or in addition to) manipulating images of
79 * Rewrote `vidwhacker' to use the new image-grabbing
81 * Made fading work on TrueColor XFree86 4.x systems.
82 * Fixed a subtle rendering bug in `atlantis' (the fish
84 * Made `atlantis' have a texture simulating light
85 reflections from the surface of the ocean.
86 * Fixed up label placement in `molecule'.
87 * Better color bars in `xteevee'.
88 * Made `install-strip' not try to strip scripts.
89 Changes since 3.30: * Put in more sensible defaults for DPMS, and updated
90 the documentation to reflect the fact that all your
91 DPMS settings are now belong to xscreensaver.
92 * Fixed the `xscreensaver.spec' file so that `--force'
94 * New versions of `rotzoomer' and `nerverot'.

98 * Made `gltext' able to display the current time.
99 * Fixed a floating-point-precision problem in `gltext'
100 that sometimes caused horizontal lines to vanish.
101 * Removed the `-window-id' option from the hacks:
102 it never worked right, and was unnecessary.
103 * Made the `starwars' hack use thicker lines, antialias
104 the text, and fade out at the far edge instead of just
106 * Fixed an SHM segment leak in `moire'.
107 Changes since 3.28: * Better rendering of the new logo.
108 * New hack, `gltext'.
109 * Added `-planetary' option to `gears', to draw a
110 different kind of gear system.
111 * Made motion and rotation be smoother in `gears',
112 `glplanet', `moebius', `rubik', and `sierpinski3d'.
113 * Improved coloration in `sierpinski3d'.
114 * Made the GL hacks react to window size changes.
115 * Made most of the GL hacks take a -fps option (like
116 `pulsar' did), so you can use them to benchmark your
118 * Fixed the previous fix to `sonar'.
119 * Minor fix to `nerverot'.
120 Made sonar able to ping hosts on DEC OSF1.
121 * Eliminated a bogus "didn't get enough colors" warning
122 in some of the hacks.
123 Changes since 3.27: * New logo for xscreensaver!
124 * New hacks, `starwars' and `stonerview'.
125 * Made the motion of the bouncing ball in `stairs' be a
127 * Made newly-added screenhacks be added to .xscreensaver
128 automatically: if there are hacks in the app-defaults
129 file that are not also in ~/.xscreensaver, they will
130 be added to the end of the list.
131 * Redid the `Screensaver Options' part of the control
132 panel; xscreensaver now lets you configure your DPMS
134 * Fixed some Makefile problems with non-GL builds.
135 * Fixed detection of MesaGL for version 3.3.
136 * Better workaround to Red Hat 7.0's broken gcc.
137 * Added Sparc Solaris kernel panic to `bsod'.
138 Changes since 3.26: * New hacks: `zoom' and `whirlwindwarp'.
139 * Fixed a free-memory-reference bug in `sonar'.
140 * Better error handling when there are no suitable GL
142 * Added diagnostic dialog when xscreensaver-demo is
143 unable to launch xscreensaver (e.g., when running as
145 * Fixed a bug that caused screenhack argument changes
146 to be ignored when xscreensaver-demo was running as
147 root (if "root" and "nobody" have different home
149 * Made the programs default to ":0" if $DISPLAY is unset.
150 * Made the `-verbose' output include information about
151 which server extensions were supported at compile time.
152 * Worked around Red Hat 7.0's broken gcc 2.96.
153 * Updated default delays on the GL hacks to look better
154 on machines with super-fast 3D hardware.
155 * Install `screensaver-properties-capplet' to work around
156 the usual egregious GNOME lossage.
157 Changes since 3.25: * Added "enabled" checkboxes in the list of hacks in
158 xscreensaver-demo (Gtk version only.)
159 * New hacks `hyperball', `xrayswarm', and `gflux'.
160 * New versions of `nerverot', `galaxy', and `hypercube'.
161 * Small fixes to `phosphor', `shadebobs', `xflame',
163 * Added external helper program `xscreensaver-gl-helper'
164 to figure out which X visual to use for OpenGL
166 * Configure updates for XFree86 4.0, and for BSD.
167 * Made it be more tolerant of bogus /etc/group files.
168 * When installing the PAM config file, first try to just
169 copy an existing "xdm" or "login" config file, so that
170 xscreensaver does authentication in the same way as the
172 Changes since 3.24: * New hack, `nerverot'.
173 * Added BSD kernel panic to `bsod'.
174 * New version of `shadebobs'.
175 * New version of `petri'.
176 * Updated `webcollage' to handle recent Altavista URL
177 format changes; made it search the AP photo gallery.
178 * Revamped command-line options of `sonar' and made it
179 properly handle subnets.
180 * The `bubbles' hack can now trickle up or down the
182 * The `xsublim' hack can now read its text from programs.
183 * Support for GLE version 3 in `extrusion'.
184 * Fixed compilation problems in `maze'.
185 * Fixed a rare crash in `flow'.
186 * Fixes for minor installation problems.
187 Changes since 3.23: * Added `-ignorant' option to `maze' hack.
188 * Updates to `critical', `bsod', `xflame', and `flow'.
189 * Added support for Kerberos 5 (via its Kerberos 4
190 compatibility layer.)
191 * Fixed a bad leak in `xteevee'.
192 * Updated `webcollage' to handle recent Altavista URL
194 * Removed xscreensaver-demo's `Ok' and `Cancel' buttons,
195 since they were confusing people: all changes are now
197 * Made xscreensaver-demo install itself into the Gnome
199 Changes since 3.22: * Fixed some misplaced text fields in the Motif version
200 of xscreensaver-demo; fixed a crash in the Gtk version
201 that would happen if the programs list was empty.
202 * Fixed a recently-introduced bug in `pulsar'.
203 * Made `sierpinski3d' use solid tetrahedrons instead of
205 * Added `-trace' option to `xmatrix'.
206 * Added new hacks `xteevee' and `xspirograph'.
207 Changes since 3.21: * Fixed some bugs in xscreensaver-demo.
208 * Rewrote the Motif version of xscreensaver-demo to
209 match the new Gtk version.
210 * The Athena toolkit is no longer supported.
211 Changes since 3.20: * Tweaked the xscreensaver-demo UI (Gtk only.)
212 * Fixed a few visual selection bugs. I think the proper
213 GL visual should be used with nVidia systems now.
214 * Made the Makefiles obey $install_prefix.
215 * Made the `xscreensaver.spec' file able to generate both
216 GL and non-GL packages simultaneously.
217 Changes since 3.19: * Added new hacks `ripples' and `sierpinski3d'.
218 * Made `xscreensaver-command -exit' be silent when no
219 screen saver was running (instead of complaining.)
220 * Made `webcollage' and `vidwhacker' use `xloadimage'
221 when available (in addition to `xli' and `xv'.)
222 * Improved memory usage in `petri' and gave it a hard
223 cap on how much memory it can allocate.
224 * Added `-watch' option to `xscreensaver-command'.
225 * Made `xscreensaver-demo' come up with the
226 most-recently-run hack selected by default.
227 * Rewrote the Gtk version of `xscreensaver-demo'.
228 It's a lot easier to use now.
229 * Extended the format of the programs list in the
230 .xscreensaver file, for the benefit of the new
231 capabilities of `xscreensaver-demo'.
232 NOTE: you might want to delete your ~/.xscreensaver
233 file and allow it to be re-created! The old one
234 should still work, but xscreensaver-demo won't be as
236 Changes since 3.18: * Fixed gcc dependencies in `bumps' and `ccurve'.
237 * New hack, `extrusion'.
238 * Some of the web sites that `webcollage' was using as
239 its sources changed formats; tweaked it to understand
241 * Added typeahead in the password dialog: if the screen
242 is locked, and you unlock it by typing a character,
243 that key will be automatically inserted in the
244 password dialog (unless it is Return, Enter, Space,
245 or a non-printing key like Shift.)
246 * Made `xmatrix' take a `-small' option, since some
247 folks with tiny screens prefer a smaller font.
248 Changes since 3.17: * New versions of `shadebobs', `lmorph', and `distort'.
249 * Added `ccurve', `blaster', and `bumps' hacks.
250 * Replaced `forest' hack with a rewritten version.
251 * Worked around a Xinerama server bug.
252 * Fixed a bug I introduced in 3.10 that caused some
253 hacks to print out superfluous warnings about not
254 having gotten enough colors.
255 * Made `sproingies' obey the `-delay' option.
256 * Fixed a portability bug in `shadebobs'.
257 * Made `webcollage' and `vidwhacker' use `xli' in
258 preference to `xv', if it is available.
259 * Added a new source of images to `webcollage'.
260 * If running under KDE, xscreensaver will add itself to
261 KDE's list of screensavers (via xscreensaver.kss.)
262 * Improved detection of GL libraries.
263 * Made the password dialog include the date and time.
264 Changes since 3.16: * New version of `webcollage' -- deals better with
265 corrupted images, and can use an http proxy.
266 * New hack, `xsublim' (run it in the background,
267 rather than adding it to the programs list.)
268 * The xscreensaver daemon was leaking a file descriptor
269 each time you edited your .xscreensaver file. Fixed.
270 Changes since 3.15: * New version of `shadebobs'.
271 * Improved image selection in `webcollage', and sped it
273 * Made configure find the right version of perl.
274 * Rewrote the CGI part of `webcollage'.
275 * `make clean' was deleting some things it shouldn't.
276 * Fixed a typo in the default programs list.
277 Changes since 3.14: * Added `webcollage' and `shadebobs' hacks.
278 * Added a `-stdout' arg to `vidwhacker' so that it can
279 be used in a pipeline.
280 * Made `petri' use less memory.
281 Changes since 3.13: * Various improvements to the Gtk port.
282 * Turned off PAM by default on Solaris, since PAM seems
283 generally to be misconfigured out-of-the-box.
284 * Made the `--without-gtk' configure option work.
285 * Made configure check the Gtk version number, since it
287 * Fixed a bug in the code that attempted to prevent
288 changes of screen resolution while the screen is
290 * Fixed a race condition in `xscreensaver-demo' that
291 could cause an X error at startup.
292 * Added `-transparent' option to `deluxe'.
293 * Added `petri' hack.
294 Changes since 3.12: * Ported `xscreensaver-demo' to Gtk.
295 * Made it possible to build Motif, Gtk, and Athena
296 versions of `xscreensaver-demo' in the same directory
297 without reconfiguring.
298 * Made `xscreensaver-demo' chase symlinks before writing
299 the .xscreensaver file, so that if .xscreensaver is
300 itself a symlink, the underlying file will be replaced
302 * Some Makefile and configure tweaks for Solaris and
304 * Made it possible to set the fire color in `xflame'.
305 * Made transparency work in TrueColor (for `goop' and
307 * Fixed a multi-head bug introduced by the virtual
309 Changes since 3.11: * Made it so that you can't scroll the screen while the
310 lock dialog is up (with XFree86 virtual viewports.)
311 * Fixed a bug in `flag' that caused bob's chin to get cut
312 off after a few iterations.
313 Changes since 3.10: * Made `xjack' be black-on-white-ish, so that it looks
314 less like a computer screen and more like the
315 typewritten paper it's supposed to be.
316 * New version of `pulsar'.
317 * Fixed Solaris compilation problem in `phosphor'.
318 * Made xscreensaver notice XFree86's virtual root window
319 hack, so that if the X server's root window is larger
320 than the monitor's displayable resolution, the screen
321 saver will limit itself to the area that actually
322 appears on the screen.
323 * Made the xscreensaver daemon do a better job of
324 picking the visual class that should be used for GL
325 programs. Less user intervention should be needed
326 now: you can use the logical visual name `GL' instead
327 of having to figure out by hand which one to use.
328 * Oops, the visual was defaulting to "best" instead of
329 "default", because the .xscreensaver file was not being
330 loaded quite early enough.
331 * Made configure figure out how to build icmp ping
332 support into the `sonar' hack automatically.
333 * Made warnings about not being able to read shadow
334 passwords not be printed if compiled with PAM support.
335 * Improved PAM startup diagnostics.
336 * Worked around the Solaris PAM bug that was causing
337 crashes there, so now PAM is turned on by default.
338 * Made configure detect the number of arguments that
339 pam_strerror() takes, since on Linux, this apparently
340 changed between 2.0 and 2.2, sigh.
341 * Made the /proc/interrupts kludge look for "PS/2 Mouse"
342 as well as "keyboard".
343 * Made xscreensaver notice when there has been a sudden
344 large jump in wall-clock time, and if so, lock right
345 away, instead of waiting for "lockTimeout" to expire
346 first. (Laptops need this for safer recovery from
348 * Added `-throttle' option to `xscreensaver-command'.
349 Changes since 3.09: * Added `phosphor', `xmatrix', and `pulsar' hacks.
350 * Fixed a bug in the color allocator that sometimes
351 caused `starfish' to fall back to monochrome.
352 * Reduced the amount of code that runs before root
353 privileges are disavowed: "normal" and "shadow"
354 passwords now do some initialization as root, but the
355 PAM and Kerberos authorization schemes will be
356 initialized while running as "nobody". Supposedly
357 this closes a potential security hole when using
359 * Added some more sanity checking to configure.
360 Changes since 3.08: * Added `compass', `squiral', `xflame', `wander',
361 `spotlight', and `critical' hacks.
362 * Added some new modes to `decayscreen'.
363 * Made `deluxe' work in monochrome.
364 * Generalized usage of the Double-Buffer server extension
365 in several hacks (`compass', `deluxe', `interference',
366 `kumppa', and `moire2'.)
367 * Fixed another visual-depth problem in `rd-bomb'.
368 * The screen saver will now defer blanking if neither
369 the keyboard nor the mouse could be grabbed. Instead,
370 it will just try again in a few minutes. This fixes
371 a bad interaction between xscreensaver and programs
372 like VMware that hold the mouse and keyboard grabbed
374 * Added a new erase mode (expanding spiral.)
375 Changes since 3.07: * Fixed some bugs in my port of `t3d'.
376 * Added `penetrate' and `deluxe' hacks.
377 * When linking against Motif 2.x, also link against XPM.
378 * Added support for using /proc/interrupts for idle
379 detection on Linux. Now xscreensaver shouldn't kick
380 in when the user is active on a non-X virtual console.
381 * Upgraded to autoconf 2.13.
382 Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
383 in properly; check for _Xsetlocale in -lXintl.)
384 * Portability fixes for sonar.c.
385 * Fixed a compilation problem when you have GL but don't
387 * Made configure notice when MesaGL requires -lpthread.
388 * Made `flame' ignore SIGFPE (not sure if this is the
389 right fix; it seems only to be needed on FreeBSD.)
390 * Kludged `rd-bomb' work on visuals that are of depth 24
391 but that *do not* support pixmaps of depth 32.
392 * Fixed `halo' to work properly in TrueColor.
393 * Changed `xscreensaver.spec' to install the hacks in
394 /usr/X11R6/lib/xscreensaver/ by default, since that's
395 where recent Red Hat distributions put them.
397 * Updated versions of `crystal', `hopalong', and `flow'
399 * Imported `demon' and `loop' modes from xlockmore.
400 Changes since 3.05: * Oops, the "default-n" visual descriptor was broken;
401 it was always installing a colormap if the
402 `installColormap' preference was set, meaning that
403 `xearth', `xv' and friends were using the wrong
404 colors on 8-bit systems.
405 * Turned off HAVE_PING in `sonar', since it compiles
406 on some Linux systems, but not others of similar
408 Changes since 3.04: * Fixed an off-by-1 in `distort'.
409 * Added `sonar' hack.
410 * New version of `glplanet' (with stars.)
411 * Made all hacks exit when you type `q' or `ESC' at them,
412 and made them obey the WM_DELETE_WINDOW ClientMessage.
413 * Fixed a nonfatal buffer overrun in lament (note:
414 lament still doesn't work with MesaGL 3.0: it dies in
415 lambda_textured_triangle1(), which is Mesa's bug, not
417 Changes since 3.03: * Added an `xscreensaver.spec' file, to make it easier
418 for other folks to generate RPMs.
419 * Made the password code work on HPUX in the situation
420 where: ``enhanced security'' is available; but not
421 used; but the user typed a password more than 8
422 characters long anyway. FTSOHPUX.
423 Changes since 3.02: * Made locking work when passwd aging is enabled.
424 * Added support for PAM (Pluggable Authentication
425 Modules.) It is still turned off by default, though,
426 since it doesn't seem to work on Solaris 2.6, and has
427 been behaving erratically on Red Hat 5.1.
428 * Made each possible authentication method be tried in
429 turn until one succeeds; this means that Kerberos is
430 being used, we will first check Kerberos, and if that
431 fails, will then consult the local password file.
433 * Save and restore the bits under the passwd dialog,
434 to avoid leaving a black rectangle behind when
435 unlocking is cancelled.
436 Changes since 3.01: * Not everyone has sys/select.h, sigh...
437 Changes since 3.00: * Some fixes to `reflect'.
439 * Made it log unsuccessful attempts to unlock the screen
441 * Fixed a bug where `xscreensaver-demo' could be seeing
442 a different programs list than `xscreensaver' did.
443 Changes since 2.34: * The xscreensaver daemon no longer links against Motif
444 or Athena: demo-mode and the preferences panel are no
445 longer built in to the daemon, but are now handled by
446 an external program, `xscreensaver-demo'.
447 (I decided that this, along with the recent addition
448 of the `.xscreensaver' config file, justified bumping
449 the version number to 3.00, since this is a fairly
450 major architectural change.)
451 * Lines in the `*programs' resource may now begin with
452 the character "-", meaning "don't run this hack."
453 In this way, it's possible to disable a hack without
454 throwing away the information about it (making it
455 easier to change your mind later.) Eventually the
456 preferences/demo mode GUI should represent this as a
457 checkbox or something.
458 * Fixed a short race condition where it was possible for
459 xscreensaver to die with a BadWindow error if it was
460 blanking the screen just as another window was being
462 * Made it possible to disable specific modes in `bsod'.
463 Changes since 2.33: * Fixed a bug that was making `pipes' generate way too
464 many valves. Made the viewpoint in `pipes' be selected
465 randomly instead of always being -10 degrees.
466 * Fixed a bug in the XSHM code, in the case where the
467 server supports the XSHM extension but is not the same
468 machine as the client.
469 * Made `rd-bomb' default to taking up the whole screen.
470 * Made it not try to do fading/unfading if no PseudoColor
472 * Initial attempt at supporting VT-locking (doesn't work
474 * Eliminated the `captureStdout' resource; now
475 `captureStderr' controls both streams.
476 * Added `-capture-stderr' and `-no-capture-stderr'
477 command-line arguments.
478 * Added `glplanet' hack.
479 * When a hack is selected with `xscreensaver-command
480 -select', that hack will be used until further notice
481 (until the saver turns off, or another activation
483 Changes since 2.32: * Made `xscreensaver-command' print error messages:
484 the xscreensaver daemon now responds to ClientMessage
485 events by writing a response message on a window
486 property, instead of just writing to its stderr.
487 * Made the ~/.xscreensaver file be automatically reloaded
488 when the file date changes.
489 * The password dialog and splash screen no longer depend
490 on Motif or Athena. This should clear up a number of
491 focus problems, and is the first step on the path
492 toward moving all of the Motif/Athena/whatever code
493 out of the xscreensaver daemon, and into external
495 * Don't complain about LessTif 0.86 any more, since the
496 new password dialog makes that problem go away.
497 * Configure tweaks for Irix 6.5, SunOS 5.something.
498 * New `-reflect' option to `distort'.
499 Changes since 2.31: * Added reading and writing of a ~/.xscreensaver file,
500 so that the Preferences panel can save its settings.
501 * New version of `rubik'.
502 * Added `-select N' argument to `xscreensaver-command'.
503 * Oops, left out some of the `bubbles3d' files...
504 Changes since 2.30: * The cursor was invisible in the password dialog. Fixed.
505 * Made configure warn against MesaGL 2.6.
506 * Fixed X error at startup when using non-default visual.
507 * New version of `crystal', `ant', and `atlantis' from
509 * New hack, `bubble3d'.
510 * Added some new modes to `bsod'.
511 Changes since 2.29: * Changed the order in which -lSM and -lICE are linked
512 to be after Motif instead of before (Lesstif on Irix
514 Changes since 2.28: * Work around a bash bug in configure.
515 * Tweaked HPUX paths again. FTSOHPUX.
516 * Made configure recommend against LessTif 0.86, due
517 to a bug in that version that causes a security hole
518 in the screen locking code. LessTif 0.87 will fix it.
519 * Made all of the `--with' options to `configure' accept
520 a directory option as well (so that --with-motif=/FOO
521 will add -I/FOO/include -L/FOO/lib). I believe this is
522 the Configure Party Line of how do to such things.
523 * Fixed a bug where the mouse was left un-grabbed
524 after the first time the graphics hack was changed
525 (simplified all of the mouse-grabbing logic.)
526 * Maybe possibly perhaps made `vidwhacker' really not
527 leave stray xv windows around. This time for sure.
528 * Added a new erase mode (random dots fizzling out.)
529 * Added `-prefs' argument to `xscreensaver-command',
530 that brings up the Preferences dialog directly (it
531 seems that nobody ever noticed the `Preferences' button
532 on the Demo Mode dialog, maybe this will help.)
533 * Added a splash screen. Turn it off with *splash:false.
534 Changes since 2.27: * Better macsbug text in `bsod'.
535 * New version of `distort' with many new modes.
536 * Plugged a leak in `coral'.

538 * Removed some compiler warnings.
539 * More consistent usage of stderr versus stdout.
540 * More diagnostics should an X error occur.
541 * Fixed a possible crash in SGI-specific unfading code.
542 Changes since 2.26: * Improved version of `distort'.
543 * Made `lament' compile against OpenGL 1.0 (though it
544 still requires 1.1 to work properly.)
545 * Updated my email address and home page.
546 Changes since 2.24: * Improved motion in `rd-bomb'.
547 * Added XSHM (shared memory extension) support to the

549 `swirl' hacks, which speeds them up a bit.
550 * Added `lament' hack.
551 Changes since 2.23: * Tweaked the order of the -L options again.
552 * Cleaned up configure's `--help' message.
553 * Added `kumppa' hack.
554 * Smarter maze-solving algorithm in `maze'.
555 * Took `xlyap' out of the default list of hacks, since
556 it's just incredibly buggy (and slow.) Maybe someday
557 someone will fix it...
558 * Added `distort' hack, but didn't add it to the default
559 list (yet) because it's still too slow.
560 * Made the Athena demo dialog look more like the Motif
561 version; it has a text-entry field now, too.
562 * Made the Athena password dialog echo asterisks, like
563 Motif does, instead of using a flyspeck font.
564 * Some random configure tweaks.
565 * Added a `timestamp' resource that makes the `-verbose'
566 messages include the time at which they were printed.

570 Changes since 2.21: * Added support for the DPMS server extension (Display
571 Power Management System.)
572 * Made configure advertize the `--enable-subdir' option a
573 little more, since that seemed to cause some people
574 stress. Also, made that directory be built into the
575 xscreensaver executable, as a hardcoded prefix to
576 $PATH. (Might help, shouldn't hurt.)
577 * Made configure prefer the two-arg gettimeofday to the
578 one-arg version, since AIX doesn't have any prototypes.
579 * Made it work with Xaw3d (the 3D Athena library.)
580 * Made `make install' create directories as necessary.
581 * New version of lmorph from Sverre.
582 * Added `crystal' and `discreet' hacks from xlockmore.
583 * Added a new mode to `bsod'.
584 Changes since 2.20: * Made `xscreensaver-command -time' use different words.
585 (It now describes the two states as "screen blanked
586 since..." and "screen non-blanked since..." instead of
587 "active since..." and "inactive since..." which a lot
588 of people interpreted as meaning the opposite of what
590 * Improved some error messages, in the hopes of making
591 the distinction between the xscreensaver and
592 xscreensaver-command programs more obvious.
593 * Rewrote (and reorganized) parts of the xscreensaver and
594 xscreensaver-command manual pages.
595 * Renamed xscreensaver's `-lock' command-line option to
596 be `-lock-mode', to avoid confusion with the `-lock'
597 option to xscreensaver-command, which does a totally
599 * Removed xscreensaver's `-demo' command-line option for
600 a similar reason; use `xscreensaver-command -demo'
602 * Disabled SGI's ``scheme'' nonsense in a better way than
603 fully-qualifying the background colors in every single
605 * Fixed some other minor cosmetic problems when *sgiMode
607 * Fixed an X error in `bsod -root' (how ironic...)
608 Changes since 2.19: * Fixed a bug that caused the mouse to sometimes not be
609 grabbed properly (meaning the window manager menu could
610 pop up over the demo-mode display.)
611 * Fixed a bug that made the stderr output sometimes get
613 * Fixed a bug that made the demo-mode scrollbar move too
615 * Protected against a possible buffer overflow.
616 * Made `vidwhacker' not leave stray xv windows around.
617 * New version of `ant' so that Bagley doesn't calve.

622 * Added `interference' hack.
623 * Added `truchet' hack.
625 * Added some new modes to `vidwhacker'.
626 Changes since 2.16: * Added a -window-id argument to most hacks, so that they
627 can draw on arbitrary externally-provided windows.
628 * Synched with xlockmore 4.11a01.
630 * Added `atlantis' GL hack.
631 * Renamed `puzzle' hack to `jigsaw', since xlock already
632 had a different mode called `puzzle'.
633 * Made it self-configure properly when Motif 2.1.0 is
634 being used (requires -lXp now, sigh...)
635 Changes since 2.15: * Made `flag' able to do XPM images.
636 * New look for the xscreensaver logo (`xroger').

649 * Split `escher' into `cage' and `moebius', as per
651 * Changed subprocess handling to use sigaction() instead
652 of signal() if it's available (this is necessary for
653 SCO but should work fine on other systems too.)
654 * Various other tweaks.
655 Changes since 2.13: * Better fix for the Motif drag-and-die lossage.
656 * Put in some kludges to work around a LessTif bug.
657 * XScreenSaver is known to work with LessTif 0.82 now.
658 * Made fading work on high-end SGI video hardware.
659 * Fixed another SGI-specific bug in screen grabbing;
660 will the madness never cease?
661 * Fixed another crash in `xlyap'.
662 Changes since 2.12: * Made `decayscreen' do directions other than down.
664 * Fixed a crash in `xlyap'.
665 * Added CDE info to the man page, removed `cde.txt'.

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

678 * Added `puzzle' hack.
679 * Added `xlyap' hack.
680 * Added `default-n' as a visual name, so that one can
681 have -install on by default, but turn it off for
682 certain poorly-behaved hacks (like xv.)
683 * Added support for grabbing frames of external video
684 (on SGI) to the screen-grabbing hacks (decayscreen,
685 slidescreen, slip, blitspin, and puzzle.)
686 * Improved look of tiles in `slidescreen'; fixed its
687 color allocation problem.

690 `rotor', and `ant' from xlockmore.
