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:
41 xscreensaver-command -demo
43 After a few seconds, the screen should go black, and a dialog box should
44 appear in the upper right corner. This is "Demo Mode".
46 Note: unlike `xlock', xscreensaver has a client-server model: the
47 `xscreensaver' process is a daemon that runs in the background; it is
48 controlled by the foreground `xscreensaver-command' program.
50 xscreensaver has an extensive manual -- please read it!
54 The xscreensaver daemon waits until the keyboard and mouse have been idle
55 for a period, and then runs a graphics demo chosen at random. The demo is
56 terminated as soon as there is any mouse or keyboard activity (or, in
57 locking mode, when the proper password is typed.)
59 It is trivially easy to add new display modes to xscreensaver: any program
60 which can be invoked in such a way that it draws on the root window of the
61 screen can be used as a screensaver. You just change a config file --
62 there's no need to recompile or reinstall anything.
66 Along with the xscreensaver daemon itself, this package also includes
67 numerous graphics hacks for use as screensavers. There is nothing magic
68 about these: they are just programs that draw on the root window.
70 More than 100 such programs are included. For details, see the xscreensaver
71 web page, or the enclosed manual pages. There are also some helpful hints
72 on customization in the xscreensaver app-defaults file (normally installed
73 in /usr/lib/X11/app-defaults/XScreenSaver.)
75 The latest version of xscreensaver is always available on the web at
76 http://www.jwz.org/xscreensaver/.
80 Changes since 3.25: * Added "enabled" checkboxes in the list of hacks in
81 xscreensaver-demo (Gtk version only.)
82 * New hacks `hyperball', `xrayswarm', and `gflux'.
83 * New versions of `nerverot', `galaxy', and `hypercube'.
84 * Small fixes to `phosphor', `shadebobs', `xflame',
86 * Added external helper program `xscreensaver-gl-helper'
87 to figure out which X visual to use for OpenGL
89 * Configure updates for XFree86 4.0, and for BSD.
90 * Made it be more tolerant of bogus /etc/group files.
91 * When installing the PAM config file, first try to just
92 copy an existing "xdm" or "login" config file, so that
93 xscreensaver does authentication in the same way as the
95 Changes since 3.24: * New hack, `nerverot'.
96 * Added BSD kernel panic to `bsod'.
97 * New version of `shadebobs'.
98 * New version of `petri'.
99 * Updated `webcollage' to handle recent Altavista URL
100 format changes; made it search the AP photo gallery.
101 * Revamped command-line options of `sonar' and made it
102 properly handle subnets.
103 * The `bubbles' hack can now trickle up or down the
105 * The `xsublim' hack can now read its text from programs.
106 * Support for GLE version 3 in `extrusion'.
107 * Fixed compilation problems in `maze'.
108 * Fixed a rare crash in `flow'.
109 * Fixes for minor installation problems.
110 Changes since 3.23: * Added `-ignorant' option to `maze' hack.
111 * Updates to `critical', `bsod', `xflame', and `flow'.
112 * Added support for Kerberos 5 (via its Kerberos 4
113 compatibility layer.)
114 * Fixed a bad leak in `xteevee'.
115 * Updated `webcollage' to handle recent Altavista URL
117 * Removed xscreensaver-demo's `Ok' and `Cancel' buttons,
118 since they were confusing people: all changes are now
120 * Made xscreensaver-demo install itself into the Gnome
122 Changes since 3.22: * Fixed some misplaced text fields in the Motif version
123 of xscreensaver-demo; fixed a crash in the Gtk version
124 that would happen if the programs list was empty.
125 * Fixed a recently-introduced bug in `pulsar'.
126 * Made `sierpinski3d' use solid tetrahedrons instead of
128 * Added `-trace' option to `xmatrix'.
129 * Added new hacks `xteevee' and `xspirograph'.
130 Changes since 3.21: * Fixed some bugs in xscreensaver-demo.
131 * Rewrote the Motif version of xscreensaver-demo to
132 match the new Gtk version.
133 * The Athena toolkit is no longer supported.
134 Changes since 3.20: * Tweaked the xscreensaver-demo UI (Gtk only.)
135 * Fixed a few visual selection bugs. I think the proper
136 GL visual should be used with nVidia systems now.
137 * Made the Makefiles obey $install_prefix.
138 * Made the `xscreensaver.spec' file able to generate both
139 GL and non-GL packages simultaneously.
140 Changes since 3.19: * Added new hacks `ripples' and `sierpinski3d'.
141 * Made `xscreensaver-command -exit' be silent when no
142 screen saver was running (instead of complaining.)
143 * Made `webcollage' and `vidwhacker' use `xloadimage'
144 when available (in addition to `xli' and `xv'.)
145 * Improved memory usage in `petri' and gave it a hard
146 cap on how much memory it can allocate.
147 * Added `-watch' option to `xscreensaver-command'.
148 * Made `xscreensaver-demo' come up with the
149 most-recently-run hack selected by default.
150 * Rewrote the Gtk version of `xscreensaver-demo'.
151 It's a lot easier to use now.
152 * Extended the format of the programs list in the
153 .xscreensaver file, for the benefit of the new
154 capabilities of `xscreensaver-demo'.
155 NOTE: you might want to delete your ~/.xscreensaver
156 file and allow it to be re-created! The old one
157 should still work, but xscreensaver-demo won't be as
159 Changes since 3.18: * Fixed gcc dependencies in `bumps' and `ccurve'.
160 * New hack, `extrusion'.
161 * Some of the web sites that `webcollage' was using as
162 its sources changed formats; tweaked it to understand
164 * Added typeahead in the password dialog: if the screen
165 is locked, and you unlock it by typing a character,
166 that key will be automatically inserted in the
167 password dialog (unless it is Return, Enter, Space,
168 or a non-printing key like Shift.)
169 * Made `xmatrix' take a `-small' option, since some
170 folks with tiny screens prefer a smaller font.
171 Changes since 3.17: * New versions of `shadebobs', `lmorph', and `distort'.
172 * Added `ccurve', `blaster', and `bumps' hacks.
173 * Replaced `forest' hack with a rewritten version.
174 * Worked around a Xinerama server bug.
175 * Fixed a bug I introduced in 3.10 that caused some
176 hacks to print out superfluous warnings about not
177 having gotten enough colors.
178 * Made `sproingies' obey the `-delay' option.
179 * Fixed a portability bug in `shadebobs'.
180 * Made `webcollage' and `vidwhacker' use `xli' in
181 preference to `xv', if it is available.
182 * Added a new source of images to `webcollage'.
183 * If running under KDE, xscreensaver will add itself to
184 KDE's list of screensavers (via xscreensaver.kss.)
185 * Improved detection of GL libraries.
186 * Made the password dialog include the date and time.
187 Changes since 3.16: * New version of `webcollage' -- deals better with
188 corrupted images, and can use an http proxy.
189 * New hack, `xsublim' (run it in the background,
190 rather than adding it to the programs list.)
191 * The xscreensaver daemon was leaking a file descriptor
192 each time you edited your .xscreensaver file. Fixed.
193 Changes since 3.15: * New version of `shadebobs'.
194 * Improved image selection in `webcollage', and sped it
196 * Made configure find the right version of perl.
197 * Rewrote the CGI part of `webcollage'.
198 * `make clean' was deleting some things it shouldn't.
199 * Fixed a typo in the default programs list.
200 Changes since 3.14: * Added `webcollage' and `shadebobs' hacks.
201 * Added a `-stdout' arg to `vidwhacker' so that it can
202 be used in a pipeline.
203 * Made `petri' use less memory.
204 Changes since 3.13: * Various improvements to the Gtk port.
205 * Turned off PAM by default on Solaris, since PAM seems
206 generally to be misconfigured out-of-the-box.
207 * Made the `--without-gtk' configure option work.
208 * Made configure check the Gtk version number, since it
210 * Fixed a bug in the code that attempted to prevent
211 changes of screen resolution while the screen is
213 * Fixed a race condition in `xscreensaver-demo' that
214 could cause an X error at startup.
215 * Added `-transparent' option to `deluxe'.
216 * Added `petri' hack.
217 Changes since 3.12: * Ported `xscreensaver-demo' to Gtk.
218 * Made it possible to build Motif, Gtk, and Athena
219 versions of `xscreensaver-demo' in the same directory
220 without reconfiguring.
221 * Made `xscreensaver-demo' chase symlinks before writing
222 the .xscreensaver file, so that if .xscreensaver is
223 itself a symlink, the underlying file will be replaced
225 * Some Makefile and configure tweaks for Solaris and
227 * Made it possible to set the fire color in `xflame'.
228 * Made transparency work in TrueColor (for `goop' and
230 * Fixed a multi-head bug introduced by the virtual
232 Changes since 3.11: * Made it so that you can't scroll the screen while the
233 lock dialog is up (with XFree86 virtual viewports.)
234 * Fixed a bug in `flag' that caused bob's chin to get cut
235 off after a few iterations.
236 Changes since 3.10: * Made `xjack' be black-on-white-ish, so that it looks
237 less like a computer screen and more like the
238 typewritten paper it's supposed to be.
239 * New version of `pulsar'.
240 * Fixed Solaris compilation problem in `phosphor'.
241 * Made xscreensaver notice XFree86's virtual root window
242 hack, so that if the X server's root window is larger
243 than the monitor's displayable resolution, the screen
244 saver will limit itself to the area that actually
245 appears on the screen.
246 * Made the xscreensaver daemon do a better job of
247 picking the visual class that should be used for GL
248 programs. Less user intervention should be needed
249 now: you can use the logical visual name `GL' instead
250 of having to figure out by hand which one to use.
251 * Oops, the visual was defaulting to "best" instead of
252 "default", because the .xscreensaver file was not being
253 loaded quite early enough.
254 * Made configure figure out how to build icmp ping
255 support into the `sonar' hack automatically.
256 * Made warnings about not being able to read shadow
257 passwords not be printed if compiled with PAM support.
258 * Improved PAM startup diagnostics.
259 * Worked around the Solaris PAM bug that was causing
260 crashes there, so now PAM is turned on by default.
261 * Made configure detect the number of arguments that
262 pam_strerror() takes, since on Linux, this apparently
263 changed between 2.0 and 2.2, sigh.
264 * Made the /proc/interrupts kludge look for "PS/2 Mouse"
265 as well as "keyboard".
266 * Made xscreensaver notice when there has been a sudden
267 large jump in wall-clock time, and if so, lock right
268 away, instead of waiting for "lockTimeout" to expire
269 first. (Laptops need this for safer recovery from
271 * Added `-throttle' option to `xscreensaver-command'.
272 Changes since 3.09: * Added `phosphor', `xmatrix', and `pulsar' hacks.
273 * Fixed a bug in the color allocator that sometimes
274 caused `starfish' to fall back to monochrome.
275 * Reduced the amount of code that runs before root
276 privileges are disavowed: "normal" and "shadow"
277 passwords now do some initialization as root, but the
278 PAM and Kerberos authorization schemes will be
279 initialized while running as "nobody". Supposedly
280 this closes a potential security hole when using
282 * Added some more sanity checking to configure.
283 Changes since 3.08: * Added `compass', `squiral', `xflame', `wander',
284 `spotlight', and `critical' hacks.
285 * Added some new modes to `decayscreen'.
286 * Made `deluxe' work in monochrome.
287 * Generalized usage of the Double-Buffer server extension
288 in several hacks (`compass', `deluxe', `interference',
289 `kumppa', and `moire2'.)
290 * Fixed another visual-depth problem in `rd-bomb'.
291 * The screen saver will now defer blanking if neither
292 the keyboard nor the mouse could be grabbed. Instead,
293 it will just try again in a few minutes. This fixes
294 a bad interaction between xscreensaver and programs
295 like VMware that hold the mouse and keyboard grabbed
297 * Added a new erase mode (expanding spiral.)
298 Changes since 3.07: * Fixed some bugs in my port of `t3d'.
299 * Added `penetrate' and `deluxe' hacks.
300 * When linking against Motif 2.x, also link against XPM.
301 * Added support for using /proc/interrupts for idle
302 detection on Linux. Now xscreensaver shouldn't kick
303 in when the user is active on a non-X virtual console.
304 * Upgraded to autoconf 2.13.
305 Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
306 in properly; check for _Xsetlocale in -lXintl.)
307 * Portability fixes for sonar.c.
308 * Fixed a compilation problem when you have GL but don't
310 * Made configure notice when MesaGL requires -lpthread.
311 * Made `flame' ignore SIGFPE (not sure if this is the
312 right fix; it seems only to be needed on FreeBSD.)
313 * Kludged `rd-bomb' work on visuals that are of depth 24
314 but that *do not* support pixmaps of depth 32.
315 * Fixed `halo' to work properly in TrueColor.
316 * Changed `xscreensaver.spec' to install the hacks in
317 /usr/X11R6/lib/xscreensaver/ by default, since that's
318 where recent Red Hat distributions put them.
320 * Updated versions of `crystal', `hopalong', and `flow'
322 * Imported `demon' and `loop' modes from xlockmore.
323 Changes since 3.05: * Oops, the "default-n" visual descriptor was broken;
324 it was always installing a colormap if the
325 `installColormap' preference was set, meaning that
326 `xearth', `xv' and friends were using the wrong
327 colors on 8-bit systems.
328 * Turned off HAVE_PING in `sonar', since it compiles
329 on some Linux systems, but not others of similar
331 Changes since 3.04: * Fixed an off-by-1 in `distort'.
332 * Added `sonar' hack.
333 * New version of `glplanet' (with stars.)
334 * Made all hacks exit when you type `q' or `ESC' at them,
335 and made them obey the WM_DELETE_WINDOW ClientMessage.
336 * Fixed a nonfatal buffer overrun in lament (note:
337 lament still doesn't work with MesaGL 3.0: it dies in
338 lambda_textured_triangle1(), which is Mesa's bug, not
340 Changes since 3.03: * Added an `xscreensaver.spec' file, to make it easier
341 for other folks to generate RPMs.
342 * Made the password code work on HPUX in the situation
343 where: ``enhanced security'' is available; but not
344 used; but the user typed a password more than 8
345 characters long anyway. FTSOHPUX.
346 Changes since 3.02: * Made locking work when passwd aging is enabled.
347 * Added support for PAM (Pluggable Authentication
348 Modules.) It is still turned off by default, though,
349 since it doesn't seem to work on Solaris 2.6, and has
350 been behaving erratically on Red Hat 5.1.
351 * Made each possible authentication method be tried in
352 turn until one succeeds; this means that Kerberos is
353 being used, we will first check Kerberos, and if that
354 fails, will then consult the local password file.
356 * Save and restore the bits under the passwd dialog,
357 to avoid leaving a black rectangle behind when
358 unlocking is cancelled.
359 Changes since 3.01: * Not everyone has sys/select.h, sigh...
360 Changes since 3.00: * Some fixes to `reflect'.
362 * Made it log unsuccessful attempts to unlock the screen
364 * Fixed a bug where `xscreensaver-demo' could be seeing
365 a different programs list than `xscreensaver' did.
366 Changes since 2.34: * The xscreensaver daemon no longer links against Motif
367 or Athena: demo-mode and the preferences panel are no
368 longer built in to the daemon, but are now handled by
369 an external program, `xscreensaver-demo'.
370 (I decided that this, along with the recent addition
371 of the `.xscreensaver' config file, justified bumping
372 the version number to 3.00, since this is a fairly
373 major architectural change.)
374 * Lines in the `*programs' resource may now begin with
375 the character "-", meaning "don't run this hack."
376 In this way, it's possible to disable a hack without
377 throwing away the information about it (making it
378 easier to change your mind later.) Eventually the
379 preferences/demo mode GUI should represent this as a
380 checkbox or something.
381 * Fixed a short race condition where it was possible for
382 xscreensaver to die with a BadWindow error if it was
383 blanking the screen just as another window was being
385 * Made it possible to disable specific modes in `bsod'.
386 Changes since 2.33: * Fixed a bug that was making `pipes' generate way too
387 many valves. Made the viewpoint in `pipes' be selected
388 randomly instead of always being -10 degrees.
389 * Fixed a bug in the XSHM code, in the case where the
390 server supports the XSHM extension but is not the same
391 machine as the client.
392 * Made `rd-bomb' default to taking up the whole screen.
393 * Made it not try to do fading/unfading if no PseudoColor
395 * Initial attempt at supporting VT-locking (doesn't work
397 * Eliminated the `captureStdout' resource; now
398 `captureStderr' controls both streams.
399 * Added `-capture-stderr' and `-no-capture-stderr'
400 command-line arguments.
401 * Added `glplanet' hack.
402 * When a hack is selected with `xscreensaver-command
403 -select', that hack will be used until further notice
404 (until the saver turns off, or another activation
406 Changes since 2.32: * Made `xscreensaver-command' print error messages:
407 the xscreensaver daemon now responds to ClientMessage
408 events by writing a response message on a window
409 property, instead of just writing to its stderr.
410 * Made the ~/.xscreensaver file be automatically reloaded
411 when the file date changes.
412 * The password dialog and splash screen no longer depend
413 on Motif or Athena. This should clear up a number of
414 focus problems, and is the first step on the path
415 toward moving all of the Motif/Athena/whatever code
416 out of the xscreensaver daemon, and into external
418 * Don't complain about LessTif 0.86 any more, since the
419 new password dialog makes that problem go away.
420 * Configure tweaks for Irix 6.5, SunOS 5.something.
421 * New `-reflect' option to `distort'.
422 Changes since 2.31: * Added reading and writing of a ~/.xscreensaver file,
423 so that the Preferences panel can save its settings.
424 * New version of `rubik'.
425 * Added `-select N' argument to `xscreensaver-command'.
426 * Oops, left out some of the `bubbles3d' files...
427 Changes since 2.30: * The cursor was invisible in the password dialog. Fixed.
428 * Made configure warn against MesaGL 2.6.
429 * Fixed X error at startup when using non-default visual.
430 * New version of `crystal', `ant', and `atlantis' from
432 * New hack, `bubble3d'.
433 * Added some new modes to `bsod'.
434 Changes since 2.29: * Changed the order in which -lSM and -lICE are linked
435 to be after Motif instead of before (Lesstif on Irix
437 Changes since 2.28: * Work around a bash bug in configure.
438 * Tweaked HPUX paths again. FTSOHPUX.
439 * Made configure recommend against LessTif 0.86, due
440 to a bug in that version that causes a security hole
441 in the screen locking code. LessTif 0.87 will fix it.
442 * Made all of the `--with' options to `configure' accept
443 a directory option as well (so that --with-motif=/FOO
444 will add -I/FOO/include -L/FOO/lib). I believe this is
445 the Configure Party Line of how do to such things.
446 * Fixed a bug where the mouse was left un-grabbed
447 after the first time the graphics hack was changed
448 (simplified all of the mouse-grabbing logic.)
449 * Maybe possibly perhaps made `vidwhacker' really not
450 leave stray xv windows around. This time for sure.
451 * Added a new erase mode (random dots fizzling out.)
452 * Added `-prefs' argument to `xscreensaver-command',
453 that brings up the Preferences dialog directly (it
454 seems that nobody ever noticed the `Preferences' button
455 on the Demo Mode dialog, maybe this will help.)
456 * Added a splash screen. Turn it off with *splash:false.
457 Changes since 2.27: * Better macsbug text in `bsod'.
458 * New version of `distort' with many new modes.
459 * Plugged a leak in `coral'.
460 * Tweaked configure for HPUX.
461 * Removed some compiler warnings.
462 * More consistent usage of stderr versus stdout.
463 * More diagnostics should an X error occur.
464 * Fixed a possible crash in SGI-specific unfading code.
465 Changes since 2.26: * Improved version of `distort'.
466 * Made `lament' compile against OpenGL 1.0 (though it
467 still requires 1.1 to work properly.)
468 * Updated my email address and home page.
469 Changes since 2.24: * Improved motion in `rd-bomb'.
470 * Added XSHM (shared memory extension) support to the
471 `distort', `interference', `moire', `rd-bomb', and
472 `swirl' hacks, which speeds them up a bit.
473 * Added `lament' hack.
474 Changes since 2.23: * Tweaked the order of the -L options again.
475 * Cleaned up configure's `--help' message.
476 * Added `kumppa' hack.
477 * Smarter maze-solving algorithm in `maze'.
478 * Took `xlyap' out of the default list of hacks, since
479 it's just incredibly buggy (and slow.) Maybe someday
480 someone will fix it...
481 * Added `distort' hack, but didn't add it to the default
482 list (yet) because it's still too slow.
483 * Made the Athena demo dialog look more like the Motif
484 version; it has a text-entry field now, too.
485 * Made the Athena password dialog echo asterisks, like
486 Motif does, instead of using a flyspeck font.
487 * Some random configure tweaks.
488 * Added a `timestamp' resource that makes the `-verbose'
489 messages include the time at which they were printed.
490 Changes since 2.22: * The fix for SGI's ``scheme'' nonsense broke things, and
491 let the user's "*background" resource show through.
492 Fixed it in a different way.
493 Changes since 2.21: * Added support for the DPMS server extension (Display
494 Power Management System.)
495 * Made configure advertize the `--enable-subdir' option a
496 little more, since that seemed to cause some people
497 stress. Also, made that directory be built into the
498 xscreensaver executable, as a hardcoded prefix to
499 $PATH. (Might help, shouldn't hurt.)
500 * Made configure prefer the two-arg gettimeofday to the
501 one-arg version, since AIX doesn't have any prototypes.
502 * Made it work with Xaw3d (the 3D Athena library.)
503 * Made `make install' create directories as necessary.
504 * New version of lmorph from Sverre.
505 * Added `crystal' and `discreet' hacks from xlockmore.
506 * Added a new mode to `bsod'.
507 Changes since 2.20: * Made `xscreensaver-command -time' use different words.
508 (It now describes the two states as "screen blanked
509 since..." and "screen non-blanked since..." instead of
510 "active since..." and "inactive since..." which a lot
