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 3.23: * Added `-ignorant' option to `maze' hack.
81 * Updates to `critical', `bsod', `xflame', and `flow'.
82 * Added support for Kerberos 5 (via its Kerberos 4
84 * Fixed a bad leak in `xteevee'.
85 * Updated `webcollage' to handle recent Altavista URL
87 * Removed xscreensaver-demo's `Ok' and `Cancel' buttons,
88 since they were confusing people: all changes are now
90 * Made xscreensaver-demo install itself into the Gnome
92 Changes since 3.22: * Fixed some misplaced text fields in the Motif version
93 of xscreensaver-demo; fixed a crash in the Gtk version
94 that would happen if the programs list was empty.
95 * Fixed a recently-introduced bug in `pulsar'.
96 * Made `sierpinski3d' use solid tetrahedrons instead of
98 * Added `-trace' option to `xmatrix'.
99 * Added new hacks `xteevee' and `xspirograph'.
100 Changes since 3.21: * Fixed some bugs in xscreensaver-demo.
101 * Rewrote the Motif version of xscreensaver-demo to
102 match the new Gtk version.
103 * The Athena toolkit is no longer supported.
104 Changes since 3.20: * Tweaked the xscreensaver-demo UI (Gtk only.)
105 * Fixed a few visual selection bugs. I think the proper
106 GL visual should be used with nVidia systems now.
107 * Made the Makefiles obey $install_prefix.
108 * Made the `xscreensaver.spec' file able to generate both
109 GL and non-GL packages simultaneously.
110 Changes since 3.19: * Added new hacks `ripples' and `sierpinski3d'.
111 * Made `xscreensaver-command -exit' be silent when no
112 screen saver was running (instead of complaining.)
113 * Made `webcollage' and `vidwhacker' use `xloadimage'
114 when available (in addition to `xli' and `xv'.)
115 * Improved memory usage in `petri' and gave it a hard
116 cap on how much memory it can allocate.
117 * Added `-watch' option to `xscreensaver-command'.
118 * Made `xscreensaver-demo' come up with the
119 most-recently-run hack selected by default.
120 * Rewrote the Gtk version of `xscreensaver-demo'.
121 It's a lot easier to use now.
122 * Extended the format of the programs list in the
123 .xscreensaver file, for the benefit of the new
124 capabilities of `xscreensaver-demo'.
125 NOTE: you might want to delete your ~/.xscreensaver
126 file and allow it to be re-created! The old one
127 should still work, but xscreensaver-demo won't be as
129 Changes since 3.18: * Fixed gcc dependencies in `bumps' and `ccurve'.
130 * New hack, `extrusion'.
131 * Some of the web sites that `webcollage' was using as
132 its sources changed formats; tweaked it to understand
134 * Added typeahead in the password dialog: if the screen
135 is locked, and you unlock it by typing a character,
136 that key will be automatically inserted in the
137 password dialog (unless it is Return, Enter, Space,
138 or a non-printing key like Shift.)
139 * Made `xmatrix' take a `-small' option, since some
140 folks with tiny screens prefer a smaller font.
141 Changes since 3.17: * New versions of `shadebobs', `lmorph', and `distort'.
142 * Added `ccurve', `blaster', and `bumps' hacks.
143 * Replaced `forest' hack with a rewritten version.
144 * Worked around a Xinerama server bug.
145 * Fixed a bug I introduced in 3.10 that caused some
146 hacks to print out superfluous warnings about not
147 having gotten enough colors.
148 * Made `sproingies' obey the `-delay' option.
149 * Fixed a portability bug in `shadebobs'.
150 * Made `webcollage' and `vidwhacker' use `xli' in
151 preference to `xv', if it is available.
152 * Added a new source of images to `webcollage'.
153 * If running under KDE, xscreensaver will add itself to
154 KDE's list of screensavers (via xscreensaver.kss.)
155 * Improved detection of GL libraries.
156 * Made the password dialog include the date and time.
157 Changes since 3.16: * New version of `webcollage' -- deals better with
158 corrupted images, and can use an http proxy.
159 * New hack, `xsublim' (run it in the background,
160 rather than adding it to the programs list.)
161 * The xscreensaver daemon was leaking a file descriptor
162 each time you edited your .xscreensaver file. Fixed.
163 Changes since 3.15: * New version of `shadebobs'.
164 * Improved image selection in `webcollage', and sped it
166 * Made configure find the right version of perl.
167 * Rewrote the CGI part of `webcollage'.
168 * `make clean' was deleting some things it shouldn't.
169 * Fixed a typo in the default programs list.
170 Changes since 3.14: * Added `webcollage' and `shadebobs' hacks.
171 * Added a `-stdout' arg to `vidwhacker' so that it can
172 be used in a pipeline.
173 * Made `petri' use less memory.
174 Changes since 3.13: * Various improvements to the Gtk port.
175 * Turned off PAM by default on Solaris, since PAM seems
176 generally to be misconfigured out-of-the-box.
177 * Made the `--without-gtk' configure option work.
178 * Made configure check the Gtk version number, since it
180 * Fixed a bug in the code that attempted to prevent
181 changes of screen resolution while the screen is
183 * Fixed a race condition in `xscreensaver-demo' that
184 could cause an X error at startup.
185 * Added `-transparent' option to `deluxe'.
186 * Added `petri' hack.
187 Changes since 3.12: * Ported `xscreensaver-demo' to Gtk.
188 * Made it possible to build Motif, Gtk, and Athena
189 versions of `xscreensaver-demo' in the same directory
190 without reconfiguring.
191 * Made `xscreensaver-demo' chase symlinks before writing
192 the .xscreensaver file, so that if .xscreensaver is
193 itself a symlink, the underlying file will be replaced
195 * Some Makefile and configure tweaks for Solaris and
197 * Made it possible to set the fire color in `xflame'.
198 * Made transparency work in TrueColor (for `goop' and
200 * Fixed a multi-head bug introduced by the virtual
202 Changes since 3.11: * Made it so that you can't scroll the screen while the
203 lock dialog is up (with XFree86 virtual viewports.)
204 * Fixed a bug in `flag' that caused bob's chin to get cut
205 off after a few iterations.
206 Changes since 3.10: * Made `xjack' be black-on-white-ish, so that it looks
207 less like a computer screen and more like the
208 typewritten paper it's supposed to be.
209 * New version of `pulsar'.
210 * Fixed Solaris compilation problem in `phosphor'.
211 * Made xscreensaver notice XFree86's virtual root window
212 hack, so that if the X server's root window is larger
213 than the monitor's displayable resolution, the screen
214 saver will limit itself to the area that actually
215 appears on the screen.
216 * Made the xscreensaver daemon do a better job of
217 picking the visual class that should be used for GL
218 programs. Less user intervention should be needed
219 now: you can use the logical visual name `GL' instead
220 of having to figure out by hand which one to use.
221 * Oops, the visual was defaulting to "best" instead of
222 "default", because the .xscreensaver file was not being
223 loaded quite early enough.
224 * Made configure figure out how to build icmp ping
225 support into the `sonar' hack automatically.
226 * Made warnings about not being able to read shadow
227 passwords not be printed if compiled with PAM support.
228 * Improved PAM startup diagnostics.
229 * Worked around the Solaris PAM bug that was causing
230 crashes there, so now PAM is turned on by default.
231 * Made configure detect the number of arguments that
232 pam_strerror() takes, since on Linux, this apparently
233 changed between 2.0 and 2.2, sigh.
234 * Made the /proc/interrupts kludge look for "PS/2 Mouse"
235 as well as "keyboard".
236 * Made xscreensaver notice when there has been a sudden
237 large jump in wall-clock time, and if so, lock right
238 away, instead of waiting for "lockTimeout" to expire
239 first. (Laptops need this for safer recovery from
241 * Added `-throttle' option to `xscreensaver-command'.
242 Changes since 3.09: * Added `phosphor', `xmatrix', and `pulsar' hacks.
243 * Fixed a bug in the color allocator that sometimes
244 caused `starfish' to fall back to monochrome.
245 * Reduced the amount of code that runs before root
246 privileges are disavowed: "normal" and "shadow"
247 passwords now do some initialization as root, but the
248 PAM and Kerberos authorization schemes will be
249 initialized while running as "nobody". Supposedly
250 this closes a potential security hole when using
252 * Added some more sanity checking to configure.
253 Changes since 3.08: * Added `compass', `squiral', `xflame', `wander',
254 `spotlight', and `critical' hacks.
255 * Added some new modes to `decayscreen'.
256 * Made `deluxe' work in monochrome.
257 * Generalized usage of the Double-Buffer server extension
258 in several hacks (`compass', `deluxe', `interference',
259 `kumppa', and `moire2'.)
260 * Fixed another visual-depth problem in `rd-bomb'.
261 * The screen saver will now defer blanking if neither
262 the keyboard nor the mouse could be grabbed. Instead,
263 it will just try again in a few minutes. This fixes
264 a bad interaction between xscreensaver and programs
265 like VMware that hold the mouse and keyboard grabbed
267 * Added a new erase mode (expanding spiral.)
268 Changes since 3.07: * Fixed some bugs in my port of `t3d'.
269 * Added `penetrate' and `deluxe' hacks.
270 * When linking against Motif 2.x, also link against XPM.
271 * Added support for using /proc/interrupts for idle
272 detection on Linux. Now xscreensaver shouldn't kick
273 in when the user is active on a non-X virtual console.
274 * Upgraded to autoconf 2.13.
275 Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
276 in properly; check for _Xsetlocale in -lXintl.)
277 * Portability fixes for sonar.c.
278 * Fixed a compilation problem when you have GL but don't
280 * Made configure notice when MesaGL requires -lpthread.
281 * Made `flame' ignore SIGFPE (not sure if this is the
282 right fix; it seems only to be needed on FreeBSD.)
283 * Kludged `rd-bomb' work on visuals that are of depth 24
284 but that *do not* support pixmaps of depth 32.
285 * Fixed `halo' to work properly in TrueColor.
286 * Changed `xscreensaver.spec' to install the hacks in
287 /usr/X11R6/lib/xscreensaver/ by default, since that's
288 where recent Red Hat distributions put them.
290 * Updated versions of `crystal', `hopalong', and `flow'
292 * Imported `demon' and `loop' modes from xlockmore.
293 Changes since 3.05: * Oops, the "default-n" visual descriptor was broken;
294 it was always installing a colormap if the
295 `installColormap' preference was set, meaning that
296 `xearth', `xv' and friends were using the wrong
297 colors on 8-bit systems.
298 * Turned off HAVE_PING in `sonar', since it compiles
299 on some Linux systems, but not others of similar
301 Changes since 3.04: * Fixed an off-by-1 in `distort'.
302 * Added `sonar' hack.
303 * New version of `glplanet' (with stars.)
304 * Made all hacks exit when you type `q' or `ESC' at them,
305 and made them obey the WM_DELETE_WINDOW ClientMessage.
306 * Fixed a nonfatal buffer overrun in lament (note:
307 lament still doesn't work with MesaGL 3.0: it dies in
308 lambda_textured_triangle1(), which is Mesa's bug, not
310 Changes since 3.03: * Added an `xscreensaver.spec' file, to make it easier
311 for other folks to generate RPMs.
312 * Made the password code work on HPUX in the situation
313 where: ``enhanced security'' is available; but not
314 used; but the user typed a password more than 8
315 characters long anyway. FTSOHPUX.
316 Changes since 3.02: * Made locking work when passwd aging is enabled.
317 * Added support for PAM (Pluggable Authentication
318 Modules.) It is still turned off by default, though,
319 since it doesn't seem to work on Solaris 2.6, and has
320 been behaving erratically on Red Hat 5.1.
321 * Made each possible authentication method be tried in
322 turn until one succeeds; this means that Kerberos is
323 being used, we will first check Kerberos, and if that
324 fails, will then consult the local password file.
326 * Save and restore the bits under the passwd dialog,
327 to avoid leaving a black rectangle behind when
328 unlocking is cancelled.
329 Changes since 3.01: * Not everyone has sys/select.h, sigh...
330 Changes since 3.00: * Some fixes to `reflect'.
332 * Made it log unsuccessful attempts to unlock the screen
334 * Fixed a bug where `xscreensaver-demo' could be seeing
335 a different programs list than `xscreensaver' did.
336 Changes since 2.34: * The xscreensaver daemon no longer links against Motif
337 or Athena: demo-mode and the preferences panel are no
338 longer built in to the daemon, but are now handled by
339 an external program, `xscreensaver-demo'.
340 (I decided that this, along with the recent addition
341 of the `.xscreensaver' config file, justified bumping
342 the version number to 3.00, since this is a fairly
343 major architectural change.)
344 * Lines in the `*programs' resource may now begin with
345 the character "-", meaning "don't run this hack."
346 In this way, it's possible to disable a hack without
347 throwing away the information about it (making it
348 easier to change your mind later.) Eventually the
349 preferences/demo mode GUI should represent this as a
350 checkbox or something.
351 * Fixed a short race condition where it was possible for
352 xscreensaver to die with a BadWindow error if it was
353 blanking the screen just as another window was being
355 * Made it possible to disable specific modes in `bsod'.
356 Changes since 2.33: * Fixed a bug that was making `pipes' generate way too
357 many valves. Made the viewpoint in `pipes' be selected
358 randomly instead of always being -10 degrees.
359 * Fixed a bug in the XSHM code, in the case where the
360 server supports the XSHM extension but is not the same
361 machine as the client.
362 * Made `rd-bomb' default to taking up the whole screen.
363 * Made it not try to do fading/unfading if no PseudoColor
365 * Initial attempt at supporting VT-locking (doesn't work
367 * Eliminated the `captureStdout' resource; now
368 `captureStderr' controls both streams.
369 * Added `-capture-stderr' and `-no-capture-stderr'
370 command-line arguments.
371 * Added `glplanet' hack.
372 * When a hack is selected with `xscreensaver-command
373 -select', that hack will be used until further notice
374 (until the saver turns off, or another activation
376 Changes since 2.32: * Made `xscreensaver-command' print error messages:
377 the xscreensaver daemon now responds to ClientMessage
378 events by writing a response message on a window
379 property, instead of just writing to its stderr.
380 * Made the ~/.xscreensaver file be automatically reloaded
381 when the file date changes.
382 * The password dialog and splash screen no longer depend
383 on Motif or Athena. This should clear up a number of
384 focus problems, and is the first step on the path
385 toward moving all of the Motif/Athena/whatever code
386 out of the xscreensaver daemon, and into external
388 * Don't complain about LessTif 0.86 any more, since the
389 new password dialog makes that problem go away.
390 * Configure tweaks for Irix 6.5, SunOS 5.something.
391 * New `-reflect' option to `distort'.
392 Changes since 2.31: * Added reading and writing of a ~/.xscreensaver file,
393 so that the Preferences panel can save its settings.
394 * New version of `rubik'.
395 * Added `-select N' argument to `xscreensaver-command'.
396 * Oops, left out some of the `bubbles3d' files...
397 Changes since 2.30: * The cursor was invisible in the password dialog. Fixed.
398 * Made configure warn against MesaGL 2.6.
399 * Fixed X error at startup when using non-default visual.
400 * New version of `crystal', `ant', and `atlantis' from
402 * New hack, `bubble3d'.
403 * Added some new modes to `bsod'.
404 Changes since 2.29: * Changed the order in which -lSM and -lICE are linked
405 to be after Motif instead of before (Lesstif on Irix
407 Changes since 2.28: * Work around a bash bug in configure.
408 * Tweaked HPUX paths again. FTSOHPUX.
409 * Made configure recommend against LessTif 0.86, due
410 to a bug in that version that causes a security hole
411 in the screen locking code. LessTif 0.87 will fix it.
412 * Made all of the `--with' options to `configure' accept
413 a directory option as well (so that --with-motif=/FOO
414 will add -I/FOO/include -L/FOO/lib). I believe this is
415 the Configure Party Line of how do to such things.
416 * Fixed a bug where the mouse was left un-grabbed
417 after the first time the graphics hack was changed
418 (simplified all of the mouse-grabbing logic.)
419 * Maybe possibly perhaps made `vidwhacker' really not
420 leave stray xv windows around. This time for sure.
421 * Added a new erase mode (random dots fizzling out.)
422 * Added `-prefs' argument to `xscreensaver-command',
423 that brings up the Preferences dialog directly (it
424 seems that nobody ever noticed the `Preferences' button
425 on the Demo Mode dialog, maybe this will help.)
426 * Added a splash screen. Turn it off with *splash:false.
427 Changes since 2.27: * Better macsbug text in `bsod'.
428 * New version of `distort' with many new modes.
429 * Plugged a leak in `coral'.
430 * Tweaked configure for HPUX.
431 * Removed some compiler warnings.
432 * More consistent usage of stderr versus stdout.
433 * More diagnostics should an X error occur.
434 * Fixed a possible crash in SGI-specific unfading code.
435 Changes since 2.26: * Improved version of `distort'.
436 * Made `lament' compile against OpenGL 1.0 (though it
437 still requires 1.1 to work properly.)
438 * Updated my email address and home page.
439 Changes since 2.24: * Improved motion in `rd-bomb'.
440 * Added XSHM (shared memory extension) support to the
441 `distort', `interference', `moire', `rd-bomb', and
442 `swirl' hacks, which speeds them up a bit.
443 * Added `lament' hack.
444 Changes since 2.23: * Tweaked the order of the -L options again.
445 * Cleaned up configure's `--help' message.
446 * Added `kumppa' hack.
447 * Smarter maze-solving algorithm in `maze'.
448 * Took `xlyap' out of the default list of hacks, since
449 it's just incredibly buggy (and slow.) Maybe someday
450 someone will fix it...
451 * Added `distort' hack, but didn't add it to the default
452 list (yet) because it's still too slow.
453 * Made the Athena demo dialog look more like the Motif
454 version; it has a text-entry field now, too.
455 * Made the Athena password dialog echo asterisks, like
456 Motif does, instead of using a flyspeck font.
457 * Some random configure tweaks.
458 * Added a `timestamp' resource that makes the `-verbose'
459 messages include the time at which they were printed.
460 Changes since 2.22: * The fix for SGI's ``scheme'' nonsense broke things, and
461 let the user's "*background" resource show through.
462 Fixed it in a different way.
463 Changes since 2.21: * Added support for the DPMS server extension (Display
464 Power Management System.)
465 * Made configure advertize the `--enable-subdir' option a
466 little more, since that seemed to cause some people
467 stress. Also, made that directory be built into the
468 xscreensaver executable, as a hardcoded prefix to
469 $PATH. (Might help, shouldn't hurt.)
470 * Made configure prefer the two-arg gettimeofday to the
471 one-arg version, since AIX doesn't have any prototypes.
472 * Made it work with Xaw3d (the 3D Athena library.)
473 * Made `make install' create directories as necessary.
474 * New version of lmorph from Sverre.
475 * Added `crystal' and `discreet' hacks from xlockmore.
476 * Added a new mode to `bsod'.
477 Changes since 2.20: * Made `xscreensaver-command -time' use different words.
478 (It now describes the two states as "screen blanked
479 since..." and "screen non-blanked since..." instead of
480 "active since..." and "inactive since..." which a lot
481 of people interpreted as meaning the opposite of what
483 * Improved some error messages, in the hopes of making
484 the distinction between the xscreensaver and
485 xscreensaver-command programs more obvious.
486 * Rewrote (and reorganized) parts of the xscreensaver and
487 xscreensaver-command manual pages.
488 * Renamed xscreensaver's `-lock' command-line option to
489 be `-lock-mode', to avoid confusion with the `-lock'
490 option to xscreensaver-command, which does a totally
492 * Removed xscreensaver's `-demo' command-line option for
493 a similar reason; use `xscreensaver-command -demo'
495 * Disabled SGI's ``scheme'' nonsense in a better way than
496 fully-qualifying the background colors in every single
498 * Fixed some other minor cosmetic problems when *sgiMode
500 * Fixed an X error in `bsod -root' (how ironic...)
501 Changes since 2.19: * Fixed a bug that caused the mouse to sometimes not be
502 grabbed properly (meaning the window manager menu could
503 pop up over the demo-mode display.)
504 * Fixed a bug that made the stderr output sometimes get
506 * Fixed a bug that made the demo-mode scrollbar move too
508 * Protected against a possible buffer overflow.
509 * Made `vidwhacker' not leave stray xv windows around.
510 * New version of `ant' so that Bagley doesn't calve.
511 * Make configure on AIX get XShm from the right library.
512 Changes since 2.18: * One file was missing from the tar file. Fixed.
513 Changes since 2.17: * Oops, atlantis wasn't being built by default. Fixed.
