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 3.20: * Tweaked the xscreensaver-demo UI (Gtk only.)
81 * Fixed a few visual selection bugs. I think the proper
82 GL visual should be used with nVidia systems now.
83 * Made the Makefiles obey $install_prefix.
84 * Made the `xscreensaver.spec' file able to generate both
85 GL and non-GL packages simultaniously.
86 Changes since 3.19: * Added new hacks `ripples' and `sierpinski3d'.
87 * Made `xscreensaver-command -exit' be silent when no
88 screen saver was running (instead of complaining.)
89 * Made `webcollage' and `vidwhacker' use `xloadimage'
90 when available (in addition to `xli' and `xv'.)
91 * Improved memory usage in `petri' and gave it a hard
92 cap on how much memory it can allocate.
93 * Added `-watch' option to `xscreensaver-command'.
94 * Made `xscreensaver-demo' come up with the
95 most-recently-run hack selected by default.
96 * Rewrote the Gtk version of `xscreensaver-demo'.
97 It's a lot easier to use now.
98 * Extended the format of the programs list in the
99 .xscreensaver file, for the benefit of the new
100 capabilities of `xscreensaver-demo'.
101 NOTE: you might want to delete your ~/.xscreensaver
102 file and allow it to be re-created! The old one
103 should still work, but xscreensaver-demo won't be as
105 Changes since 3.18: * Fixed gcc dependencies in `bumps' and `ccurve'.
106 * New hack, `extrusion'.
107 * Some of the web sites that `webcollage' was using as
108 its sources changed formats; tweaked it to understand
110 * Added typeahead in the password dialog: if the screen
111 is locked, and you unlock it by typing a character,
112 that key will be automatically inserted in the
113 password dialog (unless it is Return, Enter, Space,
114 or a non-printing key like Shift.)
115 * Made `xmatrix' take a `-small' option, since some
116 folks with tiny screens prefer a smaller font.
117 Changes since 3.17: * New versions of `shadebobs', `lmorph', and `distort'.
118 * Added `ccurve', `blaster', and `bumps' hacks.
119 * Replaced `forest' hack with a rewritten version.
120 * Worked around a Xinerama server bug.
121 * Fixed a bug I introduced in 3.10 that caused some
122 hacks to print out superfluous warnings about not
123 having gotten enough colors.
124 * Made `sproingies' obey the `-delay' option.
125 * Fixed a portability bug in `shadebobs'.
126 * Made `webcollage' and `vidwhacker' use `xli' in
127 preference to `xv', if it is available.
128 * Added a new source of images to `webcollage'.
129 * If running under KDE, xscreensaver will add itself to
130 KDE's list of screensavers (via xscreensaver.kss.)
131 * Improved detection of GL libraries.
132 * Made the password dialog include the date and time.
133 Changes since 3.16: * New version of `webcollage' -- deals better with
134 corrupted images, and can use an http proxy.
135 * New hack, `xsublim' (run it in the background,
136 rather than adding it to the programs list.)
137 * The xscreensaver daemon was leaking a file descriptor
138 each time you edited your .xscreensaver file. Fixed.
139 Changes since 3.15: * New version of `shadebobs'.
140 * Improved image selection in `webcollage', and sped it
142 * Made configure find the right version of perl.
143 * Rewrote the CGI part of `webcollage'.
144 * `make clean' was deleting some things it shouldn't.
145 * Fixed a typo in the default programs list.
146 Changes since 3.14: * Added `webcollage' and `shadebobs' hacks.
147 * Added a `-stdout' arg to `vidwhacker' so that it can
148 be used in a pipeline.
149 * Made `petri' use less memory.
150 Changes since 3.13: * Various improvements to the Gtk port.
151 * Turned off PAM by default on Solaris, since PAM seems
152 generally to be misconfigured out-of-the-box.
153 * Made the `--without-gtk' configure option work.
154 * Made configure check the Gtk version number, since it
156 * Fixed a bug in the code that attempted to prevent
157 changes of screen resolution while the screen is
159 * Fixed a race condition in `xscreensaver-demo' that
160 could cause an X error at startup.
161 * Added `-transparent' option to `deluxe'.
162 * Added `petri' hack.
163 Changes since 3.12: * Ported `xscreensaver-demo' to Gtk.
164 * Made it possible to build Motif, Gtk, and Athena
165 versions of `xscreensaver-demo' in the same directory
166 without reconfiguring.
167 * Made `xscreensaver-demo' chase symlinks before writing
168 the .xscreensaver file, so that if .xscreensaver is
169 itself a symlink, the underlying file will be replaced
171 * Some Makefile and configure tweaks for Solaris and
173 * Made it possible to set the fire color in `xflame'.
174 * Made transparency work in TrueColor (for `goop' and
176 * Fixed a multi-head bug introduced by the virtual
178 Changes since 3.11: * Made it so that you can't scroll the screen while the
179 lock dialog is up (with XFree86 virtual viewports.)
180 * Fixed a bug in `flag' that caused bob's chin to get cut
181 off after a few iterations.
182 Changes since 3.10: * Made `xjack' be black-on-white-ish, so that it looks
183 less like a computer screen and more like the
184 typewritten paper it's supposed to be.
185 * New version of `pulsar'.
186 * Fixed Solaris compilation problem in `phosphor'.
187 * Made xscreensaver notice XFree86's virtual root window
188 hack, so that if the X server's root window is larger
189 than the monitor's displayable resolution, the screen
190 saver will limit itself to the area that actually
191 appears on the screen.
192 * Made the xscreensaver daemon do a better job of
193 picking the visual class that should be used for GL
194 programs. Less user intervention should be needed
195 now: you can use the logical visual name `GL' instead
196 of having to figure out by hand which one to use.
197 * Oops, the visual was defaulting to "best" instead of
198 "default", because the .xscreensaver file was not being
199 loaded quite early enough.
200 * Made configure figure out how to build icmp ping
201 support into the `sonar' hack automatically.
202 * Made warnings about not being able to read shadow
203 passwords not be printed if compiled with PAM support.
204 * Improved PAM startup diagnostics.
205 * Worked around the Solaris PAM bug that was causing
206 crashes there, so now PAM is turned on by default.
207 * Made configure detect the number of arguments that
208 pam_strerror() takes, since on Linux, this apparently
209 changed between 2.0 and 2.2, sigh.
210 * Made the /proc/interrupts kludge look for "PS/2 Mouse"
211 as well as "keyboard".
212 * Made xscreensaver notice when there has been a sudden
213 large jump in wall-clock time, and if so, lock right
214 away, instead of waiting for "lockTimeout" to expire
215 first. (Laptops need this for safer recovery from
217 * Added `-throttle' option to `xscreensaver-command'.
218 Changes since 3.09: * Added `phosphor', `xmatrix', and `pulsar' hacks.
219 * Fixed a bug in the color allocator that sometimes
220 caused `starfish' to fall back to monochrome.
221 * Reduced the amount of code that runs before root
222 privileges are disavowed: "normal" and "shadow"
223 passwords now do some initialization as root, but the
224 PAM and Kerberos authorization schemes will be
225 initialized while running as "nobody". Supposedly
226 this closes a potential security hole when using
228 * Added some more sanity checking to configure.
229 Changes since 3.08: * Added `compass', `squiral', `xflame', `wander',
230 `spotlight', and `critical' hacks.
231 * Added some new modes to `decayscreen'.
232 * Made `deluxe' work in monochrome.
233 * Generalized usage of the Double-Buffer server extension
234 in several hacks (`compass', `deluxe', `interference',
235 `kumppa', and `moire2'.)
236 * Fixed another visual-depth problem in `rd-bomb'.
237 * The screen saver will now defer blanking if neither
238 the keyboard nor the mouse could be grabbed. Instead,
239 it will just try again in a few minutes. This fixes
240 a bad interaction between xscreensaver and programs
241 like VMware that hold the mouse and keyboard grabbed
243 * Added a new erase mode (expanding spiral.)
244 Changes since 3.07: * Fixed some bugs in my port of `t3d'.
245 * Added `penetrate' and `deluxe' hacks.
246 * When linking against Motif 2.x, also link against XPM.
247 * Added support for using /proc/interrupts for idle
248 detection on Linux. Now xscreensaver shouldn't kick
249 in when the user is active on a non-X virtual console.
250 * Upgraded to autoconf 2.13.
251 Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
252 in properly; check for _Xsetlocale in -lXintl.)
253 * Portability fixes for sonar.c.
254 * Fixed a compilation problem when you have GL but don't
256 * Made configure notice when MesaGL requires -lpthread.
257 * Made `flame' ignore SIGFPE (not sure if this is the
258 right fix; it seems only to be needed on FreeBSD.)
259 * Kludged `rd-bomb' work on visuals that are of depth 24
260 but that *do not* support pixmaps of depth 32.
261 * Fixed `halo' to work properly in TrueColor.
262 * Changed `xscreensaver.spec' to install the hacks in
263 /usr/X11R6/lib/xscreensaver/ by default, since that's
264 where recent Red Hat distributions put them.
266 * Updated versions of `crystal', `hopalong', and `flow'
268 * Imported `demon' and `loop' modes from xlockmore.
269 Changes since 3.05: * Oops, the "default-n" visual descriptor was broken;
270 it was always installing a colormap if the
271 `installColormap' preference was set, meaning that
272 `xearth', `xv' and friends were using the wrong
273 colors on 8-bit systems.
274 * Turned off HAVE_PING in `sonar', since it compiles
275 on some Linux systems, but not others of similar
277 Changes since 3.04: * Fixed an off-by-1 in `distort'.
278 * Added `sonar' hack.
279 * New version of `glplanet' (with stars.)
280 * Made all hacks exit when you type `q' or `ESC' at them,
281 and made them obey the WM_DELETE_WINDOW ClientMessage.
282 * Fixed a nonfatal buffer overrun in lament (note:
283 lament still doesn't work with MesaGL 3.0: it dies in
284 lambda_textured_triangle1(), which is Mesa's bug, not
286 Changes since 3.03: * Added an `xscreensaver.spec' file, to make it easier
287 for other folks to generate RPMs.
288 * Made the password code work on HPUX in the situation
289 where: ``enhanced security'' is available; but not
290 used; but the user typed a password more than 8
291 characters long anyway. FTSOHPUX.
292 Changes since 3.02: * Made locking work when passwd aging is enabled.
293 * Added support for PAM (Pluggable Authentication
294 Modules.) It is still turned off by default, though,
295 since it doesn't seem to work on Solaris 2.6, and has
296 been behaving erratically on Red Hat 5.1.
297 * Made each possible authentication method be tried in
298 turn until one succeeds; this means that Kerberos is
299 being used, we will first check Kerberos, and if that
300 fails, will then consult the local password file.
302 * Save and restore the bits under the passwd dialog,
303 to avoid leaving a black rectangle behind when
304 unlocking is cancelled.
305 Changes since 3.01: * Not everyone has sys/select.h, sigh...
306 Changes since 3.00: * Some fixes to `reflect'.
308 * Made it log unsuccessful attempts to unlock the screen
310 * Fixed a bug where `xscreensaver-demo' could be seeing
311 a different programs list than `xscreensaver' did.
312 Changes since 2.34: * The xscreensaver daemon no longer links against Motif
313 or Athena: demo-mode and the preferences panel are no
314 longer built in to the daemon, but are now handled by
315 an external program, `xscreensaver-demo'.
316 (I decided that this, along with the recent addition
317 of the `.xscreensaver' config file, justified bumping
318 the version number to 3.00, since this is a fairly
319 major architectural change.)
320 * Lines in the `*programs' resource may now begin with
321 the character "-", meaning "don't run this hack."
322 In this way, it's possible to disable a hack without
323 throwing away the information about it (making it
324 easier to change your mind later.) Eventually the
325 preferences/demo mode GUI should represent this as a
326 checkbox or something.
327 * Fixed a short race condition where it was possible for
328 xscreensaver to die with a BadWindow error if it was
329 blanking the screen just as another window was being
331 * Made it possible to disable specific modes in `bsod'.
332 Changes since 2.33: * Fixed a bug that was making `pipes' generate way too
333 many valves. Made the viewpoint in `pipes' be selected
334 randomly instead of always being -10 degrees.
335 * Fixed a bug in the XSHM code, in the case where the
336 server supports the XSHM extension but is not the same
337 machine as the client.
338 * Made `rd-bomb' default to taking up the whole screen.
339 * Made it not try to do fading/unfading if no PseudoColor
341 * Initial attempt at supporting VT-locking (doesn't work
343 * Eliminated the `captureStdout' resource; now
344 `captureStderr' controls both streams.
345 * Added `-capture-stderr' and `-no-capture-stderr'
346 command-line arguments.
347 * Added `glplanet' hack.
348 * When a hack is selected with `xscreensaver-command
349 -select', that hack will be used until further notice
350 (until the saver turns off, or another activation
352 Changes since 2.32: * Made `xscreensaver-command' print error messages:
353 the xscreensaver daemon now responds to ClientMessage
354 events by writing a response message on a window
355 property, instead of just writing to its stderr.
356 * Made the ~/.xscreensaver file be automatically reloaded
357 when the file date changes.
358 * The password dialog and splash screen no longer depend
359 on Motif or Athena. This should clear up a number of
360 focus problems, and is the first step on the path
361 toward moving all of the Motif/Athena/whatever code
362 out of the xscreensaver daemon, and into external
364 * Don't complain about LessTif 0.86 any more, since the
365 new password dialog makes that problem go away.
366 * Configure tweaks for Irix 6.5, SunOS 5.something.
367 * New `-reflect' option to `distort'.
368 Changes since 2.31: * Added reading and writing of a ~/.xscreensaver file,
369 so that the Preferences panel can save its settings.
370 * New version of `rubik'.
371 * Added `-select N' argument to `xscreensaver-command'.
372 * Oops, left out some of the `bubbles3d' files...
373 Changes since 2.30: * The cursor was invisible in the password dialog. Fixed.
374 * Made configure warn against MesaGL 2.6.
375 * Fixed X error at startup when using non-default visual.
376 * New version of `crystal', `ant', and `atlantis' from
378 * New hack, `bubble3d'.
379 * Added some new modes to `bsod'.
380 Changes since 2.29: * Changed the order in which -lSM and -lICE are linked
381 to be after Motif instead of before (Lesstif on Irix
383 Changes since 2.28: * Work around a bash bug in configure.
384 * Tweaked HPUX paths again. FTSOHPUX.
385 * Made configure recommend against LessTif 0.86, due
386 to a bug in that version that causes a security hole
387 in the screen locking code. LessTif 0.87 will fix it.
388 * Made all of the `--with' options to `configure' accept
389 a directory option as well (so that --with-motif=/FOO
390 will add -I/FOO/include -L/FOO/lib). I believe this is
391 the Configure Party Line of how do to such things.
392 * Fixed a bug where the mouse was left un-grabbed
393 after the first time the graphics hack was changed
394 (simplified all of the mouse-grabbing logic.)
395 * Maybe possibly perhaps made `vidwhacker' really not
396 leave stray xv windows around. This time for sure.
397 * Added a new erase mode (random dots fizzling out.)
398 * Added `-prefs' argument to `xscreensaver-command',
399 that brings up the Preferences dialog directly (it
400 seems that nobody ever noticed the `Preferences' button
401 on the Demo Mode dialog, maybe this will help.)
402 * Added a splash screen. Turn it off with *splash:false.
403 Changes since 2.27: * Better macsbug text in `bsod'.
404 * New version of `distort' with many new modes.
405 * Plugged a leak in `coral'.
406 * Tweaked configure for HPUX.
407 * Removed some compiler warnings.
408 * More consistent usage of stderr versus stdout.
409 * More diagnostics should an X error occur.
410 * Fixed a possible crash in SGI-specific unfading code.
411 Changes since 2.26: * Improved version of `distort'.
412 * Made `lament' compile against OpenGL 1.0 (though it
413 still requires 1.1 to work properly.)
414 * Updated my email address and home page.
415 Changes since 2.24: * Improved motion in `rd-bomb'.
416 * Added XSHM (shared memory extension) support to the
417 `distort', `interference', `moire', `rd-bomb', and
418 `swirl' hacks, which speeds them up a bit.
419 * Added `lament' hack.
420 Changes since 2.23: * Tweaked the order of the -L options again.
421 * Cleaned up configure's `--help' message.
422 * Added `kumppa' hack.
423 * Smarter maze-solving algorithm in `maze'.
424 * Took `xlyap' out of the default list of hacks, since
425 it's just incredibly buggy (and slow.) Maybe someday
426 someone will fix it...
427 * Added `distort' hack, but didn't add it to the default
428 list (yet) because it's still too slow.
429 * Made the Athena demo dialog look more like the Motif
430 version; it has a text-entry field now, too.
431 * Made the Athena password dialog echo asterisks, like
432 Motif does, instead of using a flyspeck font.
433 * Some random configure tweaks.
434 * Added a `timestamp' resource that makes the `-verbose'
435 messages include the time at which they were printed.
436 Changes since 2.22: * The fix for SGI's ``scheme'' nonsense broke things, and
437 let the user's "*background" resource show through.
438 Fixed it in a different way.
439 Changes since 2.21: * Added support for the DPMS server extension (Display
440 Power Management System.)
441 * Made configure advertize the `--enable-subdir' option a
442 little more, since that seemed to cause some people
443 stress. Also, made that directory be built into the
444 xscreensaver executable, as a hardcoded prefix to
445 $PATH. (Might help, shouldn't hurt.)
446 * Made configure prefer the two-arg gettimeofday to the
447 one-arg version, since AIX doesn't have any prototypes.
448 * Made it work with Xaw3d (the 3D Athena library.)
449 * Made `make install' create directories as necessary.
450 * New version of lmorph from Sverre.
451 * Added `crystal' and `discreet' hacks from xlockmore.
452 * Added a new mode to `bsod'.
453 Changes since 2.20: * Made `xscreensaver-command -time' use different words.
454 (It now describes the two states as "screen blanked
455 since..." and "screen non-blanked since..." instead of
456 "active since..." and "inactive since..." which a lot
457 of people interpreted as meaning the opposite of what
459 * Improved some error messages, in the hopes of making
460 the distinction between the xscreensaver and
461 xscreensaver-command programs more obvious.
462 * Rewrote (and reorganized) parts of the xscreensaver and
463 xscreensaver-command manual pages.
464 * Renamed xscreensaver's `-lock' command-line option to
465 be `-lock-mode', to avoid confusion with the `-lock'
466 option to xscreensaver-command, which does a totally
468 * Removed xscreensaver's `-demo' command-line option for
469 a similar reason; use `xscreensaver-command -demo'
471 * Disabled SGI's ``scheme'' nonsense in a better way than
472 fully-qualifying the background colors in every single
474 * Fixed some other minor cosmetic problems when *sgiMode
476 * Fixed an X error in `bsod -root' (how ironic...)
477 Changes since 2.19: * Fixed a bug that caused the mouse to sometimes not be
478 grabbed properly (meaning the window manager menu could
479 pop up over the demo-mode display.)
480 * Fixed a bug that made the stderr output sometimes get
482 * Fixed a bug that made the demo-mode scrollbar move too
484 * Protected against a possible buffer overflow.
485 * Made `vidwhacker' not leave stray xv windows around.
486 * New version of `ant' so that Bagley doesn't calve.
487 * Make configure on AIX get XShm from the right library.
488 Changes since 2.18: * One file was missing from the tar file. Fixed.
489 Changes since 2.17: * Oops, atlantis wasn't being built by default. Fixed.
490 * Added `epicycle' hack.
491 * Added `interference' hack.
492 * Added `truchet' hack.
494 * Added some new modes to `vidwhacker'.
495 Changes since 2.16: * Added a -window-id argument to most hacks, so that they
496 can draw on arbitrary externally-provided windows.
497 * Synched with xlockmore 4.11a01.
499 * Added `atlantis' GL hack.
500 * Renamed `puzzle' hack to `jigsaw', since xlock already
501 had a different mode called `puzzle'.
502 * Made it self-configure properly when Motif 2.1.0 is
503 being used (requires -lXp now, sigh...)
504 Changes since 2.15: * Made `flag' able to do XPM images.
505 * New look for the xscreensaver logo (`xroger').
506 * Fixed compilation error on Suns with adjunct passwords.
507 * Got multi-architecture builds working again.
508 * Some configure tweaks for building on HPUX and Solaris.
509 * Fixed bug in decayscreen.
510 * Fixed typo in passwd.c.
511 * Made `cynosure' not die when colormap is full.
