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, you might want to delete your ~/.xscreensaver file.
28 If you don't, you might not see the new graphics modes. If you are upgrading
29 from version 2.* to version 3.*, definitely do delete your .xscreensaver file.
31 If you think you've found a bug, please let me know! No bug report is too
32 small. But first, please read the enclosed `README.debugging' file to find
33 out what kind of information would be most helpful to include in your bug
38 You can try out xscreensaver like so:
43 Note: unlike `xlock', xscreensaver has a client-server model: the
44 `xscreensaver' process is a daemon that runs in the background; it is
45 controlled by the foreground `xscreensaver-demo' program.
47 xscreensaver has an extensive manual -- please read it!
51 The xscreensaver daemon waits until the keyboard and mouse have been idle
52 for a period, and then runs a graphics demo chosen at random. The demo is
53 terminated as soon as there is any mouse or keyboard activity (or, in
54 locking mode, when the proper password is typed.)
56 It is trivially easy to add new display modes to xscreensaver: any program
57 which can be invoked in such a way that it draws on the root window of the
58 screen can be used as a screensaver. You just change a config file --
59 there's no need to recompile or reinstall anything.
63 Along with the xscreensaver daemon itself, this package also includes
64 numerous graphics hacks for use as screensavers. There is nothing magic
65 about these: they are just programs that draw on the root window.
67 More than 100 such programs are included. For details, see the xscreensaver
68 web page, or the enclosed manual pages. There are also some helpful hints
69 on customization in the xscreensaver app-defaults file (normally installed
70 in /usr/lib/X11/app-defaults/XScreenSaver.)
72 The latest version of xscreensaver is always available on the web at
73 http://www.jwz.org/xscreensaver/.
77 Changes since 3.27: * New logo for xscreensaver!
78 * New hacks, `starwars' and `stonerview'.
79 * Made the motion of the bouncing ball in `stairs' be a
81 * Made newly-added screenhacks be added to .xscreensaver
82 automatically: if there are hacks in the app-defaults
83 file that are not also in ~/.xscreensaver, they will
84 be added to the end of the list.
85 * Redid the `Screensaver Options' part of the control
86 panel; xscreensaver now lets you configure your DPMS
88 * Fixed some Makefile problems with non-GL builds.
89 * Fixed detection of MesaGL for version 3.3.
90 * Better workaround to Red Hat 7.0's broken gcc.
91 * Added Sparc Solaris kernel panic to `bsod'.
92 Changes since 3.26: * New hacks: `zoom' and `whirlwindwarp'.
93 * Fixed a free-memory-reference bug in `sonar'.
94 * Better error handling when there are no suitable GL
96 * Added diagnostic dialog when xscreensaver-demo is
97 unable to launch xscreensaver (e.g., when running as
99 * Fixed a bug that caused screenhack argument changes
100 to be ignored when xscreensaver-demo was running as
101 root (if "root" and "nobody" have different home
103 * Made the programs default to ":0" if $DISPLAY is unset.
104 * Made the `-verbose' output include information about
105 which server extensions were supported at compile time.
106 * Worked around Red Hat 7.0's broken gcc 2.96.
107 * Updated default delays on the GL hacks to look better
108 on machines with super-fast 3D hardware.
109 * Install `screensaver-properties-capplet' to work around
110 the usual egregious GNOME lossage.
111 Changes since 3.25: * Added "enabled" checkboxes in the list of hacks in
112 xscreensaver-demo (Gtk version only.)
113 * New hacks `hyperball', `xrayswarm', and `gflux'.
114 * New versions of `nerverot', `galaxy', and `hypercube'.
115 * Small fixes to `phosphor', `shadebobs', `xflame',
117 * Added external helper program `xscreensaver-gl-helper'
118 to figure out which X visual to use for OpenGL
120 * Configure updates for XFree86 4.0, and for BSD.
121 * Made it be more tolerant of bogus /etc/group files.
122 * When installing the PAM config file, first try to just
123 copy an existing "xdm" or "login" config file, so that
124 xscreensaver does authentication in the same way as the
126 Changes since 3.24: * New hack, `nerverot'.
127 * Added BSD kernel panic to `bsod'.
128 * New version of `shadebobs'.
129 * New version of `petri'.
130 * Updated `webcollage' to handle recent Altavista URL
131 format changes; made it search the AP photo gallery.
132 * Revamped command-line options of `sonar' and made it
133 properly handle subnets.
134 * The `bubbles' hack can now trickle up or down the
136 * The `xsublim' hack can now read its text from programs.
137 * Support for GLE version 3 in `extrusion'.
138 * Fixed compilation problems in `maze'.
139 * Fixed a rare crash in `flow'.
140 * Fixes for minor installation problems.
141 Changes since 3.23: * Added `-ignorant' option to `maze' hack.
142 * Updates to `critical', `bsod', `xflame', and `flow'.
143 * Added support for Kerberos 5 (via its Kerberos 4
144 compatibility layer.)
145 * Fixed a bad leak in `xteevee'.
146 * Updated `webcollage' to handle recent Altavista URL
148 * Removed xscreensaver-demo's `Ok' and `Cancel' buttons,
149 since they were confusing people: all changes are now
151 * Made xscreensaver-demo install itself into the Gnome
153 Changes since 3.22: * Fixed some misplaced text fields in the Motif version
154 of xscreensaver-demo; fixed a crash in the Gtk version
155 that would happen if the programs list was empty.
156 * Fixed a recently-introduced bug in `pulsar'.
157 * Made `sierpinski3d' use solid tetrahedrons instead of
159 * Added `-trace' option to `xmatrix'.
160 * Added new hacks `xteevee' and `xspirograph'.
161 Changes since 3.21: * Fixed some bugs in xscreensaver-demo.
162 * Rewrote the Motif version of xscreensaver-demo to
163 match the new Gtk version.
164 * The Athena toolkit is no longer supported.
165 Changes since 3.20: * Tweaked the xscreensaver-demo UI (Gtk only.)
166 * Fixed a few visual selection bugs. I think the proper
167 GL visual should be used with nVidia systems now.
168 * Made the Makefiles obey $install_prefix.
169 * Made the `xscreensaver.spec' file able to generate both
170 GL and non-GL packages simultaneously.
171 Changes since 3.19: * Added new hacks `ripples' and `sierpinski3d'.
172 * Made `xscreensaver-command -exit' be silent when no
173 screen saver was running (instead of complaining.)
174 * Made `webcollage' and `vidwhacker' use `xloadimage'
175 when available (in addition to `xli' and `xv'.)
176 * Improved memory usage in `petri' and gave it a hard
177 cap on how much memory it can allocate.
178 * Added `-watch' option to `xscreensaver-command'.
179 * Made `xscreensaver-demo' come up with the
180 most-recently-run hack selected by default.
181 * Rewrote the Gtk version of `xscreensaver-demo'.
182 It's a lot easier to use now.
183 * Extended the format of the programs list in the
184 .xscreensaver file, for the benefit of the new
185 capabilities of `xscreensaver-demo'.
186 NOTE: you might want to delete your ~/.xscreensaver
187 file and allow it to be re-created! The old one
188 should still work, but xscreensaver-demo won't be as
190 Changes since 3.18: * Fixed gcc dependencies in `bumps' and `ccurve'.
191 * New hack, `extrusion'.
192 * Some of the web sites that `webcollage' was using as
193 its sources changed formats; tweaked it to understand
195 * Added typeahead in the password dialog: if the screen
196 is locked, and you unlock it by typing a character,
197 that key will be automatically inserted in the
198 password dialog (unless it is Return, Enter, Space,
199 or a non-printing key like Shift.)
200 * Made `xmatrix' take a `-small' option, since some
201 folks with tiny screens prefer a smaller font.
202 Changes since 3.17: * New versions of `shadebobs', `lmorph', and `distort'.
203 * Added `ccurve', `blaster', and `bumps' hacks.
204 * Replaced `forest' hack with a rewritten version.
205 * Worked around a Xinerama server bug.
206 * Fixed a bug I introduced in 3.10 that caused some
207 hacks to print out superfluous warnings about not
208 having gotten enough colors.
209 * Made `sproingies' obey the `-delay' option.
210 * Fixed a portability bug in `shadebobs'.
211 * Made `webcollage' and `vidwhacker' use `xli' in
212 preference to `xv', if it is available.
213 * Added a new source of images to `webcollage'.
214 * If running under KDE, xscreensaver will add itself to
215 KDE's list of screensavers (via xscreensaver.kss.)
216 * Improved detection of GL libraries.
217 * Made the password dialog include the date and time.
218 Changes since 3.16: * New version of `webcollage' -- deals better with
219 corrupted images, and can use an http proxy.
220 * New hack, `xsublim' (run it in the background,
221 rather than adding it to the programs list.)
222 * The xscreensaver daemon was leaking a file descriptor
223 each time you edited your .xscreensaver file. Fixed.
224 Changes since 3.15: * New version of `shadebobs'.
225 * Improved image selection in `webcollage', and sped it
227 * Made configure find the right version of perl.
228 * Rewrote the CGI part of `webcollage'.
229 * `make clean' was deleting some things it shouldn't.
230 * Fixed a typo in the default programs list.
231 Changes since 3.14: * Added `webcollage' and `shadebobs' hacks.
232 * Added a `-stdout' arg to `vidwhacker' so that it can
233 be used in a pipeline.
234 * Made `petri' use less memory.
235 Changes since 3.13: * Various improvements to the Gtk port.
236 * Turned off PAM by default on Solaris, since PAM seems
237 generally to be misconfigured out-of-the-box.
238 * Made the `--without-gtk' configure option work.
239 * Made configure check the Gtk version number, since it
241 * Fixed a bug in the code that attempted to prevent
242 changes of screen resolution while the screen is
244 * Fixed a race condition in `xscreensaver-demo' that
245 could cause an X error at startup.
246 * Added `-transparent' option to `deluxe'.
247 * Added `petri' hack.
248 Changes since 3.12: * Ported `xscreensaver-demo' to Gtk.
249 * Made it possible to build Motif, Gtk, and Athena
250 versions of `xscreensaver-demo' in the same directory
251 without reconfiguring.
252 * Made `xscreensaver-demo' chase symlinks before writing
253 the .xscreensaver file, so that if .xscreensaver is
254 itself a symlink, the underlying file will be replaced
256 * Some Makefile and configure tweaks for Solaris and
258 * Made it possible to set the fire color in `xflame'.
259 * Made transparency work in TrueColor (for `goop' and
261 * Fixed a multi-head bug introduced by the virtual
263 Changes since 3.11: * Made it so that you can't scroll the screen while the
264 lock dialog is up (with XFree86 virtual viewports.)
265 * Fixed a bug in `flag' that caused bob's chin to get cut
266 off after a few iterations.
267 Changes since 3.10: * Made `xjack' be black-on-white-ish, so that it looks
268 less like a computer screen and more like the
269 typewritten paper it's supposed to be.
270 * New version of `pulsar'.
271 * Fixed Solaris compilation problem in `phosphor'.
272 * Made xscreensaver notice XFree86's virtual root window
273 hack, so that if the X server's root window is larger
274 than the monitor's displayable resolution, the screen
275 saver will limit itself to the area that actually
276 appears on the screen.
277 * Made the xscreensaver daemon do a better job of
278 picking the visual class that should be used for GL
279 programs. Less user intervention should be needed
280 now: you can use the logical visual name `GL' instead
281 of having to figure out by hand which one to use.
282 * Oops, the visual was defaulting to "best" instead of
283 "default", because the .xscreensaver file was not being
284 loaded quite early enough.
285 * Made configure figure out how to build icmp ping
286 support into the `sonar' hack automatically.
287 * Made warnings about not being able to read shadow
288 passwords not be printed if compiled with PAM support.
289 * Improved PAM startup diagnostics.
290 * Worked around the Solaris PAM bug that was causing
291 crashes there, so now PAM is turned on by default.
292 * Made configure detect the number of arguments that
293 pam_strerror() takes, since on Linux, this apparently
294 changed between 2.0 and 2.2, sigh.
295 * Made the /proc/interrupts kludge look for "PS/2 Mouse"
296 as well as "keyboard".
297 * Made xscreensaver notice when there has been a sudden
298 large jump in wall-clock time, and if so, lock right
299 away, instead of waiting for "lockTimeout" to expire
300 first. (Laptops need this for safer recovery from
302 * Added `-throttle' option to `xscreensaver-command'.
303 Changes since 3.09: * Added `phosphor', `xmatrix', and `pulsar' hacks.
304 * Fixed a bug in the color allocator that sometimes
305 caused `starfish' to fall back to monochrome.
306 * Reduced the amount of code that runs before root
307 privileges are disavowed: "normal" and "shadow"
308 passwords now do some initialization as root, but the
309 PAM and Kerberos authorization schemes will be
310 initialized while running as "nobody". Supposedly
311 this closes a potential security hole when using
313 * Added some more sanity checking to configure.
314 Changes since 3.08: * Added `compass', `squiral', `xflame', `wander',
315 `spotlight', and `critical' hacks.
316 * Added some new modes to `decayscreen'.
317 * Made `deluxe' work in monochrome.
318 * Generalized usage of the Double-Buffer server extension
319 in several hacks (`compass', `deluxe', `interference',
320 `kumppa', and `moire2'.)
321 * Fixed another visual-depth problem in `rd-bomb'.
322 * The screen saver will now defer blanking if neither
323 the keyboard nor the mouse could be grabbed. Instead,
324 it will just try again in a few minutes. This fixes
325 a bad interaction between xscreensaver and programs
326 like VMware that hold the mouse and keyboard grabbed
328 * Added a new erase mode (expanding spiral.)
329 Changes since 3.07: * Fixed some bugs in my port of `t3d'.
330 * Added `penetrate' and `deluxe' hacks.
331 * When linking against Motif 2.x, also link against XPM.
332 * Added support for using /proc/interrupts for idle
333 detection on Linux. Now xscreensaver shouldn't kick
334 in when the user is active on a non-X virtual console.
335 * Upgraded to autoconf 2.13.
336 Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
337 in properly; check for _Xsetlocale in -lXintl.)
338 * Portability fixes for sonar.c.
339 * Fixed a compilation problem when you have GL but don't
341 * Made configure notice when MesaGL requires -lpthread.
342 * Made `flame' ignore SIGFPE (not sure if this is the
343 right fix; it seems only to be needed on FreeBSD.)
344 * Kludged `rd-bomb' work on visuals that are of depth 24
345 but that *do not* support pixmaps of depth 32.
346 * Fixed `halo' to work properly in TrueColor.
347 * Changed `xscreensaver.spec' to install the hacks in
348 /usr/X11R6/lib/xscreensaver/ by default, since that's
349 where recent Red Hat distributions put them.
351 * Updated versions of `crystal', `hopalong', and `flow'
353 * Imported `demon' and `loop' modes from xlockmore.
354 Changes since 3.05: * Oops, the "default-n" visual descriptor was broken;
355 it was always installing a colormap if the
356 `installColormap' preference was set, meaning that
357 `xearth', `xv' and friends were using the wrong
358 colors on 8-bit systems.
359 * Turned off HAVE_PING in `sonar', since it compiles
360 on some Linux systems, but not others of similar
362 Changes since 3.04: * Fixed an off-by-1 in `distort'.
363 * Added `sonar' hack.
364 * New version of `glplanet' (with stars.)
365 * Made all hacks exit when you type `q' or `ESC' at them,
366 and made them obey the WM_DELETE_WINDOW ClientMessage.
367 * Fixed a nonfatal buffer overrun in lament (note:
368 lament still doesn't work with MesaGL 3.0: it dies in
369 lambda_textured_triangle1(), which is Mesa's bug, not
371 Changes since 3.03: * Added an `xscreensaver.spec' file, to make it easier
372 for other folks to generate RPMs.
373 * Made the password code work on HPUX in the situation
374 where: ``enhanced security'' is available; but not
375 used; but the user typed a password more than 8
376 characters long anyway. FTSOHPUX.
377 Changes since 3.02: * Made locking work when passwd aging is enabled.
378 * Added support for PAM (Pluggable Authentication
379 Modules.) It is still turned off by default, though,
380 since it doesn't seem to work on Solaris 2.6, and has
381 been behaving erratically on Red Hat 5.1.
382 * Made each possible authentication method be tried in
383 turn until one succeeds; this means that Kerberos is
384 being used, we will first check Kerberos, and if that
385 fails, will then consult the local password file.
387 * Save and restore the bits under the passwd dialog,
388 to avoid leaving a black rectangle behind when
389 unlocking is cancelled.
390 Changes since 3.01: * Not everyone has sys/select.h, sigh...
391 Changes since 3.00: * Some fixes to `reflect'.
393 * Made it log unsuccessful attempts to unlock the screen
395 * Fixed a bug where `xscreensaver-demo' could be seeing
396 a different programs list than `xscreensaver' did.
397 Changes since 2.34: * The xscreensaver daemon no longer links against Motif
398 or Athena: demo-mode and the preferences panel are no
399 longer built in to the daemon, but are now handled by
400 an external program, `xscreensaver-demo'.
401 (I decided that this, along with the recent addition
402 of the `.xscreensaver' config file, justified bumping
403 the version number to 3.00, since this is a fairly
404 major architectural change.)
405 * Lines in the `*programs' resource may now begin with
406 the character "-", meaning "don't run this hack."
407 In this way, it's possible to disable a hack without
408 throwing away the information about it (making it
409 easier to change your mind later.) Eventually the
410 preferences/demo mode GUI should represent this as a
411 checkbox or something.
412 * Fixed a short race condition where it was possible for
413 xscreensaver to die with a BadWindow error if it was
414 blanking the screen just as another window was being
416 * Made it possible to disable specific modes in `bsod'.
417 Changes since 2.33: * Fixed a bug that was making `pipes' generate way too
418 many valves. Made the viewpoint in `pipes' be selected
419 randomly instead of always being -10 degrees.
420 * Fixed a bug in the XSHM code, in the case where the
421 server supports the XSHM extension but is not the same
422 machine as the client.
423 * Made `rd-bomb' default to taking up the whole screen.
424 * Made it not try to do fading/unfading if no PseudoColor
426 * Initial attempt at supporting VT-locking (doesn't work
428 * Eliminated the `captureStdout' resource; now
429 `captureStderr' controls both streams.
430 * Added `-capture-stderr' and `-no-capture-stderr'
431 command-line arguments.
432 * Added `glplanet' hack.
433 * When a hack is selected with `xscreensaver-command
434 -select', that hack will be used until further notice
435 (until the saver turns off, or another activation
437 Changes since 2.32: * Made `xscreensaver-command' print error messages:
438 the xscreensaver daemon now responds to ClientMessage
439 events by writing a response message on a window
440 property, instead of just writing to its stderr.
441 * Made the ~/.xscreensaver file be automatically reloaded
442 when the file date changes.
443 * The password dialog and splash screen no longer depend
444 on Motif or Athena. This should clear up a number of
445 focus problems, and is the first step on the path
446 toward moving all of the Motif/Athena/whatever code
447 out of the xscreensaver daemon, and into external
449 * Don't complain about LessTif 0.86 any more, since the
450 new password dialog makes that problem go away.
451 * Configure tweaks for Irix 6.5, SunOS 5.something.
452 * New `-reflect' option to `distort'.
453 Changes since 2.31: * Added reading and writing of a ~/.xscreensaver file,
454 so that the Preferences panel can save its settings.
455 * New version of `rubik'.
456 * Added `-select N' argument to `xscreensaver-command'.
457 * Oops, left out some of the `bubbles3d' files...
458 Changes since 2.30: * The cursor was invisible in the password dialog. Fixed.
459 * Made configure warn against MesaGL 2.6.
460 * Fixed X error at startup when using non-default visual.
461 * New version of `crystal', `ant', and `atlantis' from
463 * New hack, `bubble3d'.
464 * Added some new modes to `bsod'.
465 Changes since 2.29: * Changed the order in which -lSM and -lICE are linked
466 to be after Motif instead of before (Lesstif on Irix
468 Changes since 2.28: * Work around a bash bug in configure.
469 * Tweaked HPUX paths again. FTSOHPUX.
470 * Made configure recommend against LessTif 0.86, due
471 to a bug in that version that causes a security hole
472 in the screen locking code. LessTif 0.87 will fix it.
473 * Made all of the `--with' options to `configure' accept
474 a directory option as well (so that --with-motif=/FOO
475 will add -I/FOO/include -L/FOO/lib). I believe this is
476 the Configure Party Line of how do to such things.
477 * Fixed a bug where the mouse was left un-grabbed
478 after the first time the graphics hack was changed
479 (simplified all of the mouse-grabbing logic.)
480 * Maybe possibly perhaps made `vidwhacker' really not
481 leave stray xv windows around. This time for sure.
482 * Added a new erase mode (random dots fizzling out.)
483 * Added `-prefs' argument to `xscreensaver-command',
484 that brings up the Preferences dialog directly (it
485 seems that nobody ever noticed the `Preferences' button
486 on the Demo Mode dialog, maybe this will help.)
487 * Added a splash screen. Turn it off with *splash:false.
488 Changes since 2.27: * Better macsbug text in `bsod'.
489 * New version of `distort' with many new modes.
490 * Plugged a leak in `coral'.
491 * Tweaked configure for HPUX.
492 * Removed some compiler warnings.
493 * More consistent usage of stderr versus stdout.
494 * More diagnostics should an X error occur.
495 * Fixed a possible crash in SGI-specific unfading code.
496 Changes since 2.26: * Improved version of `distort'.
497 * Made `lament' compile against OpenGL 1.0 (though it
498 still requires 1.1 to work properly.)
499 * Updated my email address and home page.
500 Changes since 2.24: * Improved motion in `rd-bomb'.
501 * Added XSHM (shared memory extension) support to the
502 `distort', `interference', `moire', `rd-bomb', and
503 `swirl' hacks, which speeds them up a bit.
504 * Added `lament' hack.
505 Changes since 2.23: * Tweaked the order of the -L options again.
506 * Cleaned up configure's `--help' message.
507 * Added `kumppa' hack.
508 * Smarter maze-solving algorithm in `maze'.
509 * Took `xlyap' out of the default list of hacks, since
510 it's just incredibly buggy (and slow.) Maybe someday
511 someone will fix it...
512 * Added `distort' hack, but didn't add it to the default
513 list (yet) because it's still too slow.
514 * Made the Athena demo dialog look more like the Motif
515 version; it has a text-entry field now, too.
516 * Made the Athena password dialog echo asterisks, like
517 Motif does, instead of using a flyspeck font.

525 Power Management System.)
526 * Made configure advertize the `--enable-subdir' option a
527 little more, since that seemed to cause some people

540 since..." and "screen non-blanked since..." instead of
541 "active since..." and "inactive since..." which a lot
542 of people interpreted as meaning the opposite of what
544 * Improved some error messages, in the hopes of making
545 the distinction between the xscreensaver and
546 xscreensaver-command programs more obvious.
547 * Rewrote (and reorganized) parts of the xscreensaver and
548 xscreensaver-command manual pages.
549 * Renamed xscreensaver's `-lock' command-line option to
550 be `-lock-mode', to avoid confusion with the `-lock'
551 option to xscreensaver-command, which does a totally
553 * Removed xscreensaver's `-demo' command-line option for
554 a similar reason; use `xscreensaver-command -demo'

557 fully-qualifying the background colors in every single
559 * Fixed some other minor cosmetic problems when *sgiMode
561 * Fixed an X error in `bsod -root' (how ironic...)

581 can draw on arbitrary externally-provided windows.
582 * Synched with xlockmore 4.11a01.
584 * Added `atlantis' GL hack.
585 * Renamed `puzzle' hack to `jigsaw', since xlock already
586 had a different mode called `puzzle'.
587 * Made it self-configure properly when Motif 2.1.0 is
588 being used (requires -lXp now, sigh...)
589 Changes since 2.15: * Made `flag' able to do XPM images.

605 * Changed subprocess handling to use sigaction() instead
606 of signal() if it's available (this is necessary for
607 SCO but should work fine on other systems too.)
608 * Various other tweaks.
609 Changes since 2.13: * Better fix for the Motif drag-and-die lossage.
610 * Put in some kludges to work around a LessTif bug.
611 * XScreenSaver is known to work with LessTif 0.82 now.
612 * Made fading work on high-end SGI video hardware.

616 Changes since 2.12: * Made `decayscreen' do directions other than down.
618 * Fixed a crash in `xlyap'.

632 * Added `puzzle' hack.
633 * Added `xlyap' hack.

638 (on SGI) to the screen-grabbing hacks (decayscreen,
639 slidescreen, slip, blitspin, and puzzle.)
