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 3.16: * New version of `webcollage' -- deals better with
81 corrupted images, and can use an http proxy.
82 * New hack, `xsublim' (run it in the background,
83 rather than adding it to the programs list.)
84 * The xscreensaver daemon was leaking a file descriptor
85 each time you edited your .xscreensaver file. Fixed.
86 Changes since 3.15: * New version of `shadebobs'.
87 * Improved image selection in `webcollage', and sped it
89 * Made configure find the right version of perl.
90 * Rewrote the CGI part of `webcollage'.
91 * `make clean' was deleting some things it shouldn't.
92 * Fixed a typo in the default programs list.
93 Changes since 3.14: * Added `webcollage' and `shadebobs' hacks.
94 * Added a `-stdout' arg to `vidwhacker' so that it can
95 be used in a pipeline.
96 * Made `petri' use less memory.
97 Changes since 3.13: * Various improvements to the Gtk port.
98 * Turned off PAM by default on Solaris, since PAM seems
99 generally to be misconfigured out-of-the-box.
100 * Made the `--without-gtk' configure option work.
101 * Made configure check the Gtk version number, since it
103 * Fixed a bug in the code that attempted to prevent
104 changes of screen resolution while the screen is
106 * Fixed a race condition in `xscreensaver-demo' that
107 could cause an X error at startup.
108 * Added `-transparent' option to `deluxe'.
109 * Added `petri' hack.
110 Changes since 3.12: * Ported `xscreensaver-demo' to Gtk.
111 * Made it possible to build Motif, Gtk, and Athena
112 versions of `xscreensaver-demo' in the same directory
113 without reconfiguring.
114 * Made `xscreensaver-demo' chase symlinks before writing
115 the .xscreensaver file, so that if .xscreensaver is
116 itself a symlink, the underlying file will be replaced
118 * Some Makefile and configure tweaks for Solaris and
120 * Made it possible to set the fire color in `xflame'.
121 * Made transparency work in TrueColor (for `goop' and
123 * Fixed a multi-head bug introduced by the virtual
125 Changes since 3.11: * Made it so that you can't scroll the screen while the
126 lock dialog is up (with XFree86 virtual viewports.)
127 * Fixed a bug in `flag' that caused bob's chin to get cut
128 off after a few iterations.
129 Changes since 3.10: * Made `xjack' be black-on-white-ish, so that it looks
130 less like a computer screen and more like the
131 typewritten paper it's supposed to be.
132 * New version of `pulsar'.
133 * Fixed Solaris compilation problem in `phosphor'.
134 * Made xscreensaver notice XFree86's virtual root window
135 hack, so that if the X server's root window is larger
136 than the monitor's displayable resolution, the screen
137 saver will limit itself to the area that actually
138 appears on the screen.
139 * Made the xscreensaver daemon do a better job of
140 picking the visual class that should be used for GL
141 programs. Less user intervention should be needed
142 now: you can use the logical visual name `GL' instead
143 of having to figure out by hand which one to use.
144 * Oops, the visual was defaulting to "best" instead of
145 "default", because the .xscreensaver file was not being
146 loaded quite early enough.
147 * Made configure figure out how to build icmp ping
148 support into the `sonar' hack automatically.
149 * Made warnings about not being able to read shadow
150 passwords not be printed if compiled with PAM support.
151 * Improved PAM startup diagnostics.
152 * Worked around the Solaris PAM bug that was causing
153 crashes there, so now PAM is turned on by default.
154 * Made configure detect the number of arguments that
155 pam_strerror() takes, since on Linux, this apparently
156 changed between 2.0 and 2.2, sigh.
157 * Made the /proc/interrupts kludge look for "PS/2 Mouse"
158 as well as "keyboard".
159 * Made xscreensaver notice when there has been a sudden
160 large jump in wall-clock time, and if so, lock right
161 away, instead of waiting for "lockTimeout" to expire
162 first. (Laptops need this for safer recovery from
164 * Added `-throttle' option to `xscreensaver-command'.
165 Changes since 3.09: * Added `phosphor', `xmatrix', and `pulsar' hacks.
166 * Fixed a bug in the color allocator that sometimes
167 caused `starfish' to fall back to monochrome.
168 * Reduced the amount of code that runs before root
169 privileges are disavowed: "normal" and "shadow"
170 passwords now do some initialization as root, but the
171 PAM and Kerberos authorization schemes will be
172 initialized while running as "nobody". Supposedly
173 this closes a potential security hole when using
175 * Added some more sanity checking to configure.
176 Changes since 3.08: * Added `compass', `squiral', `xflame', `wander',
177 `spotlight', and `critical' hacks.
178 * Added some new modes to `decayscreen'.
179 * Made `deluxe' work in monochrome.
180 * Generalized usage of the Double-Buffer server extension
181 in several hacks (`compass', `deluxe', `interference',
182 `kumppa', and `moire2'.)
183 * Fixed another visual-depth problem in `rd-bomb'.
184 * The screen saver will now defer blanking if neither
185 the keyboard nor the mouse could be grabbed. Instead,
186 it will just try again in a few minutes. This fixes
187 a bad interaction between xscreensaver and programs
188 like VMware that hold the mouse and keyboard grabbed
190 * Added a new erase mode (expanding spiral.)
191 Changes since 3.07: * Fixed some bugs in my port of `t3d'.
192 * Added `penetrate' and `deluxe' hacks.
193 * When linking against Motif 2.x, also link against XPM.
194 * Added support for using /proc/interrupts for idle
195 detection on Linux. Now xscreensaver shouldn't kick
196 in when the user is active on a non-X virtual console.
197 * Upgraded to autoconf 2.13.
198 Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
199 in properly; check for _Xsetlocale in -lXintl.)
200 * Portability fixes for sonar.c.
201 * Fixed a compilation problem when you have GL but don't
203 * Made configure notice when MesaGL requires -lpthread.
204 * Made `flame' ignore SIGFPE (not sure if this is the
205 right fix; it seems only to be needed on FreeBSD.)
206 * Kludged `rd-bomb' work on visuals that are of depth 24
207 but that *do not* support pixmaps of depth 32.
208 * Fixed `halo' to work properly in TrueColor.
209 * Changed `xscreensaver.spec' to install the hacks in
210 /usr/X11R6/lib/xscreensaver/ by default, since that's
211 where recent Red Hat distributions put them.
213 * Updated versions of `crystal', `hopalong', and `flow'
215 * Imported `demon' and `loop' modes from xlockmore.
216 Changes since 3.05: * Oops, the "default-n" visual descriptor was broken;
217 it was always installing a colormap if the
218 `installColormap' preference was set, meaning that
219 `xearth', `xv' and friends were using the wrong
220 colors on 8-bit systems.
221 * Turned off HAVE_PING in `sonar', since it compiles
222 on some Linux systems, but not others of similar
224 Changes since 3.04: * Fixed an off-by-1 in `distort'.
225 * Added `sonar' hack.
226 * New version of `glplanet' (with stars.)
227 * Made all hacks exit when you type `q' or `ESC' at them,
228 and made them obey the WM_DELETE_WINDOW ClientMessage.
229 * Fixed a nonfatal buffer overrun in lament (note:
230 lament still doesn't work with MesaGL 3.0: it dies in
231 lambda_textured_triangle1(), which is Mesa's bug, not
233 Changes since 3.03: * Added an `xscreensaver.spec' file, to make it easier
234 for other folks to generate RPMs.
235 * Made the password code work on HPUX in the situation
236 where: ``enhanced security'' is available; but not
237 used; but the user typed a password more than 8
238 characters long anyway. FTSOHPUX.
239 Changes since 3.02: * Made locking work when passwd aging is enabled.
240 * Added support for PAM (Pluggable Authentication
241 Modules.) It is still turned off by default, though,
242 since it doesn't seem to work on Solaris 2.6, and has
243 been behaving erratically on Red Hat 5.1.
244 * Made each possible authentication method be tried in
245 turn until one succeeds; this means that Kerberos is
246 being used, we will first check Kerberos, and if that
247 fails, will then consult the local password file.
249 * Save and restore the bits under the passwd dialog,
250 to avoid leaving a black rectangle behind when
251 unlocking is cancelled.
252 Changes since 3.01: * Not everyone has sys/select.h, sigh...
253 Changes since 3.00: * Some fixes to `reflect'.
255 * Made it log unsuccessful attempts to unlock the screen
257 * Fixed a bug where `xscreensaver-demo' could be seeing
258 a different programs list than `xscreensaver' did.
259 Changes since 2.34: * The xscreensaver daemon no longer links against Motif
260 or Athena: demo-mode and the preferences panel are no
261 longer built in to the daemon, but are now handled by
262 an external program, `xscreensaver-demo'.
263 (I decided that this, along with the recent addition
264 of the `.xscreensaver' config file, justified bumping
265 the version number to 3.00, since this is a fairly
266 major architectural change.)
267 * Lines in the `*programs' resource may now begin with
268 the character "-", meaning "don't run this hack."
269 In this way, it's possible to disable a hack without
270 throwing away the information about it (making it
271 easier to change your mind later.) Eventually the
272 preferences/demo mode GUI should represent this as a
273 checkbox or something.
274 * Fixed a short race condition where it was possible for
275 xscreensaver to die with a BadWindow error if it was
276 blanking the screen just as another window was being
278 * Made it possible to disable specific modes in `bsod'.
279 Changes since 2.33: * Fixed a bug that was making `pipes' generate way too
280 many valves. Made the viewpoint in `pipes' be selected
281 randomly instead of always being -10 degrees.
282 * Fixed a bug in the XSHM code, in the case where the
283 server supports the XSHM extension but is not the same
284 machine as the client.
285 * Made `rd-bomb' default to taking up the whole screen.
286 * Made it not try to do fading/unfading if no PseudoColor
288 * Initial attempt at supporting VT-locking (doesn't work
290 * Eliminated the `captureStdout' resource; now
291 `captureStderr' controls both streams.
292 * Added `-capture-stderr' and `-no-capture-stderr'
293 command-line arguments.
294 * Added `glplanet' hack.
295 * When a hack is selected with `xscreensaver-command
296 -select', that hack will be used until further notice
297 (until the saver turns off, or another activation
299 Changes since 2.32: * Made `xscreensaver-command' print error messages:
300 the xscreensaver daemon now responds to ClientMessage
301 events by writing a response message on a window
302 property, instead of just writing to its stderr.
303 * Made the ~/.xscreensaver file be automatically reloaded
304 when the file date changes.
305 * The password dialog and splash screen no longer depend
306 on Motif or Athena. This should clear up a number of
307 focus problems, and is the first step on the path
308 toward moving all of the Motif/Athena/whatever code
309 out of the xscreensaver daemon, and into external
311 * Don't complain about LessTif 0.86 any more, since the
312 new password dialog makes that problem go away.
313 * Configure tweaks for Irix 6.5, SunOS 5.something.
314 * New `-reflect' option to `distort'.
315 Changes since 2.31: * Added reading and writing of a ~/.xscreensaver file,
316 so that the Preferences panel can save its settings.
317 * New version of `rubik'.
318 * Added `-select N' argument to `xscreensaver-command'.
319 * Oops, left out some of the `bubbles3d' files...
320 Changes since 2.30: * The cursor was invisible in the password dialog. Fixed.
321 * Made configure warn against MesaGL 2.6.
322 * Fixed X error at startup when using non-default visual.
323 * New version of `crystal', `ant', and `atlantis' from
325 * New hack, `bubble3d'.
326 * Added some new modes to `bsod'.
327 Changes since 2.29: * Changed the order in which -lSM and -lICE are linked
328 to be after Motif instead of before (Lesstif on Irix
330 Changes since 2.28: * Work around a bash bug in configure.
331 * Tweaked HPUX paths again. FTSOHPUX.
332 * Made configure recommend against LessTif 0.86, due
333 to a bug in that version that causes a security hole
334 in the screen locking code. LessTif 0.87 will fix it.
335 * Made all of the `--with' options to `configure' accept
336 a directory option as well (so that --with-motif=/FOO
337 will add -I/FOO/include -L/FOO/lib). I believe this is
338 the Configure Party Line of how do to such things.
339 * Fixed a bug where the mouse was left un-grabbed
340 after the first time the graphics hack was changed
341 (simplified all of the mouse-grabbing logic.)
342 * Maybe possibly perhaps made `vidwhacker' really not
343 leave stray xv windows around. This time for sure.
344 * Added a new erase mode (random dots fizzling out.)
345 * Added `-prefs' argument to `xscreensaver-command',
346 that brings up the Preferences dialog directly (it
347 seems that nobody ever noticed the `Preferences' button
348 on the Demo Mode dialog, maybe this will help.)
349 * Added a splash screen. Turn it off with *splash:false.
350 Changes since 2.27: * Better macsbug text in `bsod'.
351 * New version of `distort' with many new modes.
352 * Plugged a leak in `coral'.
353 * Tweaked configure for HPUX.
354 * Removed some compiler warnings.
355 * More consistent usage of stderr versus stdout.
356 * More diagnostics should an X error occur.
357 * Fixed a possible crash in SGI-specific unfading code.
358 Changes since 2.26: * Improved version of `distort'.
359 * Made `lament' compile against OpenGL 1.0 (though it
360 still requires 1.1 to work properly.)
361 * Updated my email address and home page.
362 Changes since 2.24: * Improved motion in `rd-bomb'.
363 * Added XSHM (shared memory extension) support to the
364 `distort', `interference', `moire', `rd-bomb', and
365 `swirl' hacks, which speeds them up a bit.
366 * Added `lament' hack.
367 Changes since 2.23: * Tweaked the order of the -L options again.
368 * Cleaned up configure's `--help' message.
369 * Added `kumppa' hack.
370 * Smarter maze-solving algorithm in `maze'.
371 * Took `xlyap' out of the default list of hacks, since
372 it's just incredibly buggy (and slow.) Maybe someday
373 someone will fix it...
374 * Added `distort' hack, but didn't add it to the default
375 list (yet) because it's still too slow.
376 * Made the Athena demo dialog look more like the Motif
377 version; it has a text-entry field now, too.
378 * Made the Athena password dialog echo asterisks, like
379 Motif does, instead of using a flyspeck font.
380 * Some random configure tweaks.
381 * Added a `timestamp' resource that makes the `-verbose'
382 messages include the time at which they were printed.
383 Changes since 2.22: * The fix for SGI's ``scheme'' nonsense broke things, and
384 let the user's "*background" resource show through.
385 Fixed it in a different way.
386 Changes since 2.21: * Added support for the DPMS server extension (Display
387 Power Management System.)
388 * Made configure advertize the `--enable-subdir' option a
389 little more, since that seemed to cause some people
390 stress. Also, made that directory be built into the
391 xscreensaver executable, as a hardcoded prefix to
392 $PATH. (Might help, shouldn't hurt.)
393 * Made configure prefer the two-arg gettimeofday to the
394 one-arg version, since AIX doesn't have any prototypes.
395 * Made it work with Xaw3d (the 3D Athena library.)
396 * Made `make install' create directories as necessary.
397 * New version of lmorph from Sverre.
398 * Added `crystal' and `discreet' hacks from xlockmore.
399 * Added a new mode to `bsod'.
400 Changes since 2.20: * Made `xscreensaver-command -time' use different words.
401 (It now describes the two states as "screen blanked
402 since..." and "screen non-blanked since..." instead of
403 "active since..." and "inactive since..." which a lot
404 of people interpreted as meaning the opposite of what
406 * Improved some error messages, in the hopes of making
407 the distinction between the xscreensaver and
408 xscreensaver-command programs more obvious.
409 * Rewrote (and reorganized) parts of the xscreensaver and
410 xscreensaver-command manual pages.
411 * Renamed xscreensaver's `-lock' command-line option to
412 be `-lock-mode', to avoid confusion with the `-lock'
413 option to xscreensaver-command, which does a totally
415 * Removed xscreensaver's `-demo' command-line option for
416 a similar reason; use `xscreensaver-command -demo'
418 * Disabled SGI's ``scheme'' nonsense in a better way than
419 fully-qualifying the background colors in every single
421 * Fixed some other minor cosmetic problems when *sgiMode
423 * Fixed an X error in `bsod -root' (how ironic...)
424 Changes since 2.19: * Fixed a bug that caused the mouse to sometimes not be
425 grabbed properly (meaning the window manager menu could
426 pop up over the demo-mode display.)
427 * Fixed a bug that made the stderr output sometimes get
429 * Fixed a bug that made the demo-mode scrollbar move too
431 * Protected against a possible buffer overflow.
432 * Made `vidwhacker' not leave stray xv windows around.
433 * New version of `ant' so that Bagley doesn't calve.
434 * Make configure on AIX get XShm from the right library.
435 Changes since 2.18: * One file was missing from the tar file. Fixed.
436 Changes since 2.17: * Oops, atlantis wasn't being built by default. Fixed.
437 * Added `epicycle' hack.
438 * Added `interference' hack.
439 * Added `truchet' hack.
441 * Added some new modes to `vidwhacker'.
442 Changes since 2.16: * Added a -window-id argument to most hacks, so that they
443 can draw on arbitrary externally-provided windows.
444 * Synched with xlockmore 4.11a01.
446 * Added `atlantis' GL hack.
447 * Renamed `puzzle' hack to `jigsaw', since xlock already
448 had a different mode called `puzzle'.
449 * Made it self-configure properly when Motif 2.1.0 is
450 being used (requires -lXp now, sigh...)
451 Changes since 2.15: * Made `flag' able to do XPM images.
452 * New look for the xscreensaver logo (`xroger').
453 * Fixed compilation error on Suns with adjunct passwords.
454 * Got multi-architecture builds working again.
455 * Some configure tweaks for building on HPUX and Solaris.
456 * Fixed bug in decayscreen.
457 * Fixed typo in passwd.c.
458 * Made `cynosure' not die when colormap is full.
459 Changes since 2.14: * Added `cynosure' hack.
460 * Added `moire2' hack.
461 * Tweaked `erase.c' some more.
462 * Made unfading a bit smoother.
463 * Added `vidwhacker' hack (not installed by default.)
464 * Added `stairs' hack.
465 * Split `escher' into `cage' and `moebius', as per
467 * Changed subprocess handling to use sigaction() instead
468 of signal() if it's available (this is necessary for
469 SCO but should work fine on other systems too.)
470 * Various other tweaks.
471 Changes since 2.13: * Better fix for the Motif drag-and-die lossage.
472 * Put in some kludges to work around a LessTif bug.
473 * XScreenSaver is known to work with LessTif 0.82 now.
474 * Made fading work on high-end SGI video hardware.
475 * Fixed another SGI-specific bug in screen grabbing;
476 will the madness never cease?
477 * Fixed another crash in `xlyap'.
478 Changes since 2.12: * Made `decayscreen' do directions other than down.
480 * Fixed a crash in `xlyap'.
481 * Added CDE info to the man page, removed `cde.txt'.
482 * Configure tweaks for Zippy.
483 * Turned off the signal handling in `bubbles' because
484 it was sometimes failing to die.
485 * Added `hacks/xscreensaver-sgigl.c' to make it possible
486 to run SGI's ElectroPaint hack (/usr/demos/bin/ep)
487 with xscreensaver. Finally!
488 * Fixed a buffer overrun in the locking code that some
489 wily, malicious cracker must have slipped in.
490 * Disabled Motif drag-and-drool in the dialog box
491 buttons, since it's broken in some old versions of
493 Changes since 2.11: * Added `README.debugging'.
494 * Added `puzzle' hack.
495 * Added `xlyap' hack.
496 * Added `default-n' as a visual name, so that one can
497 have -install on by default, but turn it off for
498 certain poorly-behaved hacks (like xv.)
499 * Added support for grabbing frames of external video
500 (on SGI) to the screen-grabbing hacks (decayscreen,
501 slidescreen, slip, blitspin, and puzzle.)
502 * Improved look of tiles in `slidescreen'; fixed its
503 color allocation problem.
504 Changes since 2.10: * Tweaked `blitspin', added it to the default list.
505 * Added `lissie', `mountain', `triangle', `worm',
506 `rotor', and `ant' from xlockmore.
507 * Updated `sierpinski', `galaxy', and `lisa'.
508 * Thickened the lines in `braid' and `lmorph'.
509 * Updated VMS makefiles.
510 * Renamed `fract' to `vines'.
511 * Added `xjack' hack.
512 * Made a few more hacks use erase.c, and added a few
514 * Fixed compilation problem with Sun's version of OpenGL.
515 * Added ability to use sigaction() instead of signal()
