13 ===============================================================================
15 This is the XScreenSaver source code distribution. It is strongly recommended
16 that you install a binary release rather than trying to compile it yourself.
17 Binaries are available for almost all platforms, including MacOS X. See the
18 XScreenSaver web site for details.
20 To compile on a Unix system with X11:
26 To compile on MacOS X:
28 Use the included XCode project. Requires XCode 2.4 and MacOS X 10.4.0

37 XScreenSaver has an extensive manual -- please read it!
39 ===============================================================================
41 Changes since 5.03: * Fixed a possible crash in the unlock dialog (more
42 fallout from the recent PAM changes...)
43 * New hacks, `moebiusgears', `abstractile', and
45 * Rewrote `gears' to use better (involute) gear models,
46 and to be more random.
47 * Minor updates to `cwaves', `voronoi', `deco',
48 `glcells', `rd-bomb', `fireworkx' and `webcollage'.
49 * `pong' can now display the current time as the score.
50 * `xmatrix -mode pipe' works better.
51 * Minor tweaks for compilation on MacOS 10.5.0.
52 Changes since 5.02: * New hacks, `cwaves', `glcells', `m6502', and `voronoi'.
53 * Minor fixes to `bsod'.
54 * Fixed possible crash with PAM USB-dongle auth.
55 * Updated `webcollage' to track recent Google Images
57 Changes since 5.01: * Reworked PAM code to support fingerprint readers, etc.
58 * Ported 'webcollage' to OSX.
59 * Added OSX 10.2 and 10.3 kernel panics to `bsod'.
60 * Fixed a Xinerama crash when changing the screen count.
61 * New blobbier `mirrorblob'.
62 * Minor updates to `lisa', `bsod', `ifs', `hypertorus',
63 `polytopes', `circuit', `endgame', `crackberg',
64 `flipflop', `flipscreen3d', `fliptext', and `carousel'.
65 * Enabled multi-threaded OpenGL on OSX.
66 Changes since 5.00: * Backed out recent locale-related changes, since they
67 broke far more things than they fixed.
68 * Fail gracefully with ridiculously small window sizes.
69 * `xflame' and `flag' ignore bitmap option on MacOS.
70 * `speedmine' prefs work on MacOS.
71 * Better explosions in `boxed'.
72 * More dynamic motion in `sproingies'.
73 * More options in `flipflop'.
74 * Minor updates to `topblock'.
75 * Various other minor fixes.
76 Changes since 4.24: * Ported to MacOS X! (10.4.0 or newer)
77 * API change: instead of providing a single screenhack()
78 function that does not return, screen savers using the
79 screenhack.h framework must now provide "init" and
80 "draw one frame" functions instead. All bundled savers
81 have been updated; third-party patches will need work.
82 * All image-loading happens asynchronously.
83 * xscreensaver-getimage-file caches the contents of the
84 image directory for a few hours, so consecutive runs
85 won't have to re-list the whole directory tree.
86 * New hacks, `topblock' and `glschool'.
87 * Removed `xteevee' (superceded by `xanalogtv').
88 * Added variable-sized puzzle pieces to `jigsaw'.
89 * Changes to the defaults and command-line options of
90 many hacks to make the .xml files more consistent.
91 * Reap zombies in `glslideshow' and `carousel'.
92 * `sonar' works without setuid on OSX (dgram icmp).
93 * `xmatrix -mode pipe' displays the text of a subprocess.
94 * `endgame' has higher resolution chess-piece models.
95 * `webcollage' takes a -directory option to get images
96 from a local directory.
97 * The RPM spec file no longer auto-restarts xscreensaver
98 when a new version is installed. Restart it manually.
99 Changes since 4.23: * New versions of `cube21', `glsnake', `celtic'.
100 * Backed out a DPMS-related patch that cause desktop
101 flickering with some X servers.
102 * Fixed startup crash in getgroups() when running setuid.
103 * Default to not displaying stderr on the saver window.
104 * Fixed bad free() in "Documentation" button.
105 * Don't try to run hacks that aren't installed.
106 * Minor fixes to various XML config files and man pages.
107 Changes since 4.22: * New hacks, `glhanoi', `cube21', `timetunnel',
108 `juggler3d', and `celtic'.
109 * New versions of `tangram', `webcollage', `hypertorus',
110 `polytopes', and `ripples'.
111 * `sonar' is now quiet about unresolvable hosts.
112 * Minor corrections to BASIC code in `apple2'.
113 * xscreensaver-demo now provides an RPM clue when none
114 of the hacks seem to be installed.
115 * Don't install `ant' by default, since there is some
116 Java tool of that name, which was causing confusion.
117 And also it's boring.
118 * Made screen grabbing work again on MacOS 10.4.2.
119 * No longer prints bogus warnings about ClientMessages
120 intended for the window manager.
121 * Ignore unprintable characters in passwd entry field.
122 * Fixed yet another cross-host-display image-loading
124 * `xscreensaver-command -watch' and `-time' now work
126 Changes since 4.21: * Fixed a bug in the new mouse-motion code that caused
127 the screen to never blank on multi-head non-Xinerama
129 * New hacks, `interaggregate', `antmaze', `tangram',
131 * Minor tweaks to `fiberlamp', `ifs', `slidescreen',
132 `zoom', `sonar', `fireworkx', `whirlwindwarp',
133 `bubble3d', and `rd-bomb'.
134 * Added motion blur to `blinkbox'.
135 * `bsod' now includes Longhorn's "RSOD", and OS/2.
136 * Fixed `-wireframe' usage in most hacks and man pages.
137 Changes since 4.20: * New hack: `fliptext'.
138 * Changed default configure installation directories:
139 /usr/bin/ for xscreensaver, etc.;
140 /usr/libexec/xscreensaver/ for hacks;
141 /usr/share/xscreensaver/config/ for xml files.
142 * All the text-manipulating screen savers can have their
143 text source configured via `xscreensaver-demo' now.
144 * xscreensaver.spec now builds three RPMs:
145 base (no hacks); extras (2d hacks); and gl-extras.
146 * Added `-program' and `-front' option to `gltext'.
147 * Added `-shells' to `molecule'.
148 * Fixed text-alpha glitch in `carousel'.
149 * New `pacman': the ghosts can be killed now.
150 * Fixed a bug in screen-grabbing GL hacks where images
151 would be tiled instead of scaled on machines that
152 can't do large textures.
153 * `webcollage' can hit Flickr now.
154 * New (rewritten) implementation of `ifs'.
155 * The unlock dialog can be made to have a "New Login"
156 button that will run `gdmflexiserver'. Experimental!
157 * Fixed non-ASCII display bug in `starwars'.
158 * Configure finds a default for imageDirectory.
159 * "xscreensaver-command -lock" now works even if
160 in "screensaver disabled" mode.
161 * If a bad password is typed while CapsLock is on, the
162 unlock dialog says "CapsLock?" instead of "Sorry".
163 * Mouse motion only counts as activity if the mouse moved
164 more than 10 pixels (so the screen won't unblank every
165 time you bump your desk.)
166 * New mode option "random-same": if you have multiple
167 monitors, this will run the *same* randomly chosen
168 hack on each screen, instead of different ones on each.
169 Changes since 4.19: * New hacks, `fiberlamp', `boing', `boxfit', and
171 * Rewrote `glslideshow' again: should be faster now.
172 * Sped up loading of images in GL programs.
173 * `starwars' uses texture-mapped fonts now.
174 * New `bsod' modes: tru64, hppa, and nvidia.
175 * Updates to `webcollage', `juggle', `pinion',
176 `fireworkx', `sonar', `extrusion', `substrate', and
178 Changes since 4.18: * New hacks, `substrate', `intermomentary', `fireworkx',
180 * New version of `flow'.
181 * Made /proc/interrupts work again on Linux 2.6.
182 * Made `analogtv' not hog the CPU.
183 * Made analogtv-based hacks work properly on PPC/ARM.
184 * Fixed a bad memory leak in `piecewise'.
185 * Minor updates to `sonar', `molecule', `glmatrix',
186 `galaxy', and `webcollage'.
187 * Removed support for GTK 1.x (everyone uses 2.x now.)
188 Changes since 4.17: * Oops, pay no attention to the man behind the curtain.
189 Changes since 4.16: * New hacks, `anemotaxis' and `memscroller'.
190 * Fixed a bad bug that caused `vidwhacker' to never die.
191 * Fixed normals and lighting in `polyhedra'.
192 * Don't reuse the window when changing hacks (to work
193 around bugs in some GL implementations.)
194 * Made `xscreensaver-getimage-file' skip thumbnail-sized
196 * Fixed endian problem in `barcode' on non-x86.
197 * Updates to `webcollage', `apple2', `fuzzyflakes',
198 `atunnel', and `pacman'.
199 * Timing tweaks to `bubble3d', `bouncingcow', `engine',
200 `gltext', `lavalite', `molecule', `spotlight',
201 `sballs', `boxed', `blinkbox', and `circuit'.
202 * Configure updates for Fedora core 2 / xorg 6.7.0.
203 * Compile without warnings under gcc 3.3.3.
204 * I give up: don't blank or lock the screen if we can't
205 get a keyboard grab. In that case, both choices are
207 Changes since 4.15: * New hacks, `polyhedra', `fuzzyflakes', `antinspect',
209 * Minor updates to `webcollage', `bsod', `endgame',
210 `antspotlight', `xmatrix', and `glmatrix'.
211 * Added support for the RANDR (Resize and Rotate)
212 extension to detect when the size of the desktop has
213 been changed while xscreensaver is already running.
214 * Possibly-futile attempt to work around "rdesktop"
216 * Made `xscreensaver-getimage -file' still work even if
217 imageDirectory is unset.
218 * Convert Latin1 to ASCII in `starwars' and `phosphor'
219 (since the GLUT font only has ASCII glyphs.)
220 * Fixed randomization in `noof'.
221 * Added "GetViewPortIsFullOfLies" preference to work
222 around longstanding XFree86 bug #421.
223 * Made `sonar' subnet pinging work properly on bigendian
224 machines (e.g., PPC.)
225 Changes since 4.14: * New hacks, `wormhole', `mismunch', `noof', and
227 * `phosphor' and `apple2' include vt100 emulators now:
228 this means you can do "phosphor -program top", or
229 can use either program as an xterm replacement:
230 "apple2 -text -fast -program 'xemacs -nw'".
231 * `analogtv' (and related) fill the screen better.
232 * The '-gradient' option works in `atlantis' now.
233 * Minor updates to `blinkbox', `queens', `endgame',
234 `glmatrix', `mirrorblob', `blocktube', and `molecule'.
235 * Integrated SuSE's "external passwd helper" support.
236 * Marginally better /tmp handling in various programs.
237 * Updated config defaults for xplanet 1.0.3.
239 Changes since 4.13: * New hacks, `fontglide', `apple2', `xanalogtv', `pong',
240 `gleidescope', `mirrorblob', and `blinkbox'.
241 * New version of `glsnake' (with many more models.)
242 * Another Windows crash in `bsod'; also HVX/GCOS6/TPS6.
243 * New version of `endgame'.
244 * Screen grabbing works on MacOS X.
245 * Various minor fixes.
246 Changes since 4.12: * On Xinerama systems, xscreensaver now runs one hack on
247 each monitor (just like in "real" multi-head mode)
248 instead of running one hack stretching across all the
249 screens. Note that for this to work with any 3rd party
250 screensavers, they must update their "vroot.h" file.
251 * `webcollage' and `vidwhacker' display images using
252 `xscreensaver-getimage' now.
253 * Added `ljlatest' script for use with `starwars' and
255 Changes since 4.11: * New GL hacks, `flipflop', `antspotlight', and
257 * Added VMS to `bsod'.
258 * Compile without warnings in "gcc -pedantic".
259 * Updates to `webcollage' and `queens'.
260 * Fixed a bug that could cause PAM to hang.
261 Changes since 4.10: * New hacks, `hypertorus', `cubestorm', `glknots',
262 `blocktube', and `glmatrix'.
263 * Updates to `cloudlife', `engine', `xmatrix', and
265 * Rewrote `glslideshow': it should work on somewhat
266 wimpier video cards now.
267 * Various portability tweaks.
268 Changes since 4.09: * New hacks, `cloudlife' and `klein'.
269 * Added Apple ][+, HPUX, and OS/390 sessions to BSOD.
270 * Added some Matrix Reloaded text to `xmatrix'.
271 * Updates to `webcollage', `eruption', `jigglypuff',
272 `metaballs', and `endgame'.
273 * Completely ignore the `memoryLimit' setting now,
274 since it was still causing people GL grief.
275 * Various minor fixes.
276 Changes since 4.08: * New hacks, `flyingtoasters', `bouncingcow',
277 `jigglypuff', and `glslideshow'.
278 * More models in `engine'.
279 * Rewrote `xscreensaver-getimage' to remove reliance on
280 external image loaders (xv, chbg, xloadimage, etc.)
281 and to reduce flicker when loading files.
282 * Made `gflux' and `flipscreen3d' be mouse-spinnable.
283 Changes since 4.07: * New hacks, `atunnels' and `piecewise'.
284 * Physics improvement in `fluidballs'.
285 * Various fixes for XDarwin systems (X11 on MacOS X.)
286 * Added -clock option to `barcode'.
287 * Minor fixes to `endgame', `flurry', `flipscreen3d',
289 Changes since 4.06: * New hacks, `flurry', `metaballs', `eruption',
290 `popsquares', and `barcode'.
291 * Minor updates to `maze' for high density mazes.
292 * Added double buffering to `fluidballs' and `whirlygig'.
293 * Bug fixes for running xscreensaver to a remote XFree86
294 display (which nobody would ever do...)
295 * Updated `webcollage' (faster Alta Vista searching.)
296 * Updated `glplanet' so the sun sets in the west.
297 * Updated `sproingies' with smooth, unsegmented surfaces.
298 * Fixed Perl version-sensitivity in
299 `xscreensaver-getimage-file'.
300 * Fixed GTK2 scrolling bug in `xscreensaver-demo'.
301 Changes since 4.05: * New hack, `glblur' (disabled by default, since it
302 requires fast OpenGL texture support.)
303 * New hack, `halftone'.
304 * Updates to `endgame', `queens', `bumps', `glplanet',
305 `engine', and `circuit'.
306 * New version of `menger' that uses far fewer polygons.
307 * Fixed minor bug in `critical' that could cause some
308 bogus X servers to crash.
309 * Better labels in `molecule': the labels now appear to
310 be attached to the atoms, instead of floating in front
312 * Fixed bug that could rarely cause GL hacks to fail to
313 double-buffer (causing intermittent flickering.)
314 * Fixed a relative-URL-parsing bug in `webcollage'.
315 * Fixed a bug that (sometimes) caused the window manager
316 close box to kill `xscreensaver-demo' with a crash
317 instead of a graceful exit.
318 * Updated xscreensaver.pam to the Red Hat 7.3 way.
319 * More Gnome2-related configure crap.
320 * Updated to latest `config.guess' and `config.sub'.
321 * Fixed occasional core dump in `distort'.
322 * Added a Linux fsck failure and kernel panic to `bsod'.
323 * Added MacOS X kernel panic to `bsod'.
324 * Fixed a bug in `bsod' (all bsod bugs are ironic.)
325 * Fixed a bug that caused `xscreensaver-gl-helper' to
326 print a nonsense visual ID with some versions of
327 `printf': this could cause GL programs to display
328 incorrectly (e.g., flickery.)
329 Changes since 4.04: * More `configure' tweaks to try and get things working
330 on systems that both Gtk 1.x and 2.x installed.
331 * New hack, `endgame'.
332 * Minor updates to `gltext'.
333 Changes since 4.03: * Support for GTK 2.x / GNOME 2.x.
334 * The `configure' script will now use `pkg-config' if
335 you have it, in preference to `gtk-config', etc.
336 * New hacks, `lavalite', `queens', and `anemone'.
337 * Minor updates to `spheremonics', `gltext', `xmatrix'.
338 * You can use the mouse to manually spin most of the GL
339 hacks now (when they are displaying in a window.)
340 * Fixed a bug in `webcollage' (due to recent Alta Vista
341 url changes) that was causing it to try and load
342 incorrect image URLs.
343 * Made `xscreensaver-getimage' use gdk_pixbuf if it is
344 available: this means that those hacks that load images
345 will no longer rely on "xv", "xloadimage", etc. This
346 will close a race condition that could sometimes cause
347 your desktop background to be changed; and also makes
348 it possible for those programs to operate on image
349 files when running in windowed mode.
350 * `webcollage' can now be used in conjunction with
351 `driftnet' to display images snooped from your local
352 ethernet instead of obtained from search engines.
353 * Added man pages for all the hacks that didn't have
355 Changes since 4.02: * New hack, `spheremonics'.
356 * Minor updates to `webcollage', `cage', `moebius',
357 `morph3d', `boxed', `circuit', and `helix'.
358 * `pulsar' and `extrusion' can now load texture JPEGs.
359 * `rubik' now does non-square cubes.
360 * `fluidballs' now does various sizes of balls.
361 * `menger' and `sierpinski3d' now also show polygon
363 * `molecule' displays real subscripts in the formulae.
364 * GTK internationalization/localization support.
365 * Better detection of the various versions of libxml.
366 * Upgraded to autoconf 2.53 (from 2.13.)
367 Changes since 4.01: * Plugged a few minor leaks in `xscreensaver' and
369 * New hacks, `cubenetic' and `fluidballs'.
371 * Fixed sphere projection error in `glplanet'; installed
372 a better image of earth.
373 * Added Win2K and MacOS 1 crashes to `bsod'.
374 * Put back previous (better) version of `forest' that
375 was accidentially downgraded in the last release.
376 * New version of `bumps'.
377 * Made FPS computation in GL hacks more efficient: it
378 will influence the results less, thus resulting in
379 higher (but more accurate) reported frame rates.
380 Changes since 4.00: * New hacks: `twang', `glsnake', `boxed', `sballs',
382 * New hacks `apollonian', `euler2d', `juggle',
383 `polyominoes' and `thornbird', from xlockmore.
384 * Merged recent xlockmore changes into `ant', `braid',
385 `demon', `discrete', `drift', `fadeplot', `forest',
386 `grav', `hopalong', `ifs', `laser', `lightning',
387 `lisa', `lissie', `loop', `mountain', `penrose',
388 `rotor', `sierpinski', `slip', `sphere', `spiral',
389 `strange', and `vines'.
390 * Fixed the `gltext' bug that sometimes caused
391 horizontal lines to vanish again. This time for sure.
392 * Sped up `webcollage' by adding a C helper program to
393 replace the PPM pipeline. It also pastes images
394 semi-transparently now.
395 * Added support for the gdk_pixbuf library: if this lib
396 is available, then `blitspin', `xflame', and `flag'
397 can load GIF, JPEG, and PNG images in addition to XPM
399 * Fixed a rare race condition where the desktop-grabbing
400 hacks could sometimes leave the screen wedged, if the
401 user moved the mouse exactly when they were grabbing
402 the screen image (it would un-wedge the next time the
403 saver timed out or was activated.)
404 * Fixed incorrect colors in the screen-grabbing GL hacks
405 (`gflux' and `flipscreen3d'.)
406 * Made SIGHUP restart the daemon process (though using
407 `xscreensaver-command -restart' is still the preferred
409 * Tweaks to `xspirograph'.
410 * Minor configure and portability tweaks.
411 Changes since 3.34: * Redesigned `xscreensaver-demo' GUI: it now includes
412 small-preview and per-hack configuration dialogs.
413 * Added three new modes of operation: `One Screen Saver',
414 `Blank Screen', and `Don't Blank' (in addition to the
415 historical `Random Screen Saver').
416 * Configure now defaults to installing the hacks in
417 <prefix>/lib/xscreensaver/ instead of <prefix>/bin/.
418 (Most distros already did it this way.)
419 * New GL hacks, `menger', `engine', `flipscreen3d'.
420 * Made `sierpinski3d' be more colorful.
421 * New versions of `xmatrix' and `nerverot'.
422 * Fixed a bug in `starwars' that made the font be drawn
423 with thin lines in -root mode.
424 * Fixed a bad colormap bug in `crystal' that could make
425 *subsequent* hacks malfunction!
426 * Made `gflux' able to grab screen images (`-mode grab').
427 * Updated `webcollage' for recent search engine changes.
428 * Removed most command-line options to `xscreensaver':
429 just edit the ~/.xscreensaver file instead.
430 * Improved behavior on multi-screen and Xinerama systems:
431 the mouse now stays on the screen where the user left
432 it, and the password and splash dialogs always appear
433 on the screen that has the mouse.
434 * Made the splash dialog use more Gtk-like colors;
435 made it have only two buttons, "Settings" and "Help".
436 * Made `sonar' understand `.ssh/known_hosts2' format
437 files, and be better about stripping out illegal
439 Changes since 3.33: * Turned `memoryLimit' off by default, sigh. Apparently
440 some versions of the GL libraries (appear to) allocate
441 hundreds of megs for every GL program, so `memoryLimit'
442 was causing GL programs to malfunction or crash on
444 * Improved fading on TrueColor XFree86 4.1.x systems.
445 * New GL hack, `circuit'.
446 * Added `fuzz' mode to `decayscreen'.
447 * New version of `whirlygig'.
448 * Added links to `xplanet' and `sphereEversion'.
449 * Fixed rare race condition that could make `sonar' hang.
450 * Fixed potential crash in `speedmine'.
451 * Made `xscreensaver-demo' not crash when imageDirectory
452 was set to a non-existent directory.
453 * Made `xscreensaver-getimage-video' invoke XawTV's
454 `streamer' program better.
455 * Made `phosphor' and `starwars' deal with CR, LF,
456 or CRLF line endings.
457 * Changes for Cygwin compilation environments.
458 * Made `sonar' compile on systems that can't ping.
459 * Configure changes for HPUX 10.20.
460 * Made PAM code work on Red Had 4.2 systems.
461 * Made `xscreensaver-command -deactivate' work when the
462 saver is not active: what that does is reset the idle
463 timer, as if keyboard input had been detected. This
464 was added for the benefit of people writing DVD-playing
465 software: they can now prevent the screensaver from
466 kicking in by sending a -deactivate message once a
467 minute while the movie is playing and not paused.
468 * Various minor portability tweaks.
469 Changes since 3.32: * New hacks, `speedmine' and `whirlygig'.
470 * Sped up `pyro', made the explosions look a bit better.
471 * Added better stars to `glplanet' and `starwars'.
472 * Many internal changes to `webcollage'.
473 * Some new options to `attraction'.
474 * Minor fix to `noseguy' to avoid un-erased pixels.
475 * Rewrote the screen-eraser effects so that they complete
476 in the same amount of time regardless of how slow
477 your X server is (some of them were glacial on servers
479 * Fixed a potential free memory reference that could
480 sometimes cause a crash at startup.
481 * Possibly fixed a problem that could cause the daemon
482 to crash with an X error. I was never able to
483 reproduce this problem, but I think I might have
484 figured out what caused it.
485 * Worked around a problem that caused PAM authentication
486 to fail on some Red Hat 7.x systems.
487 * Added a `memoryLimit' parameter that controls the
488 amount of memory a graphics hack may allocate: if they
489 try to allocate more than this, malloc() will fail
490 (and they will exit or (safely) crash, rather than
491 hogging memory.) Default is 50M.
492 * Made `gnome-help-browser' be the default way to display
493 man pages in `xscreensaver-demo', if running on a
495 Changes since 3.31: * The image-manipulating hacks (`slidescreen', etc.) can
496 now operate on randomly chosen image files from disk,
497 or on frames captured from the system's video input,
498 instead of (or in addition to) manipulating images of
500 * Rewrote `vidwhacker' to use the new image-grabbing
502 * Made fading work on TrueColor XFree86 4.x systems.
503 * Fixed a subtle rendering bug in `atlantis' (the fish
505 * Made `atlantis' have a texture simulating light
506 reflections from the surface of the ocean.
507 * Fixed up label placement in `molecule'.
508 * Better color bars in `xteevee'.
509 * Made `install-strip' not try to strip scripts.
510 Changes since 3.30: * Put in more sensible defaults for DPMS, and updated
511 the documentation to reflect the fact that all your
512 DPMS settings are now belong to xscreensaver.
513 * Fixed the `xscreensaver.spec' file so that `--force'
515 * New versions of `rotzoomer' and `nerverot'.
516 * Fixed an OSF/1 compilation problem in `molecule'.
517 Changes since 3.29: * New hacks, `molecule', `dangerball', and `rotzoomer'.
518 * New version of `gflux'.
519 * Made `gltext' able to display the current time.
520 * Fixed a floating-point-precision problem in `gltext'
521 that sometimes caused horizontal lines to vanish.
522 * Removed the `-window-id' option from the hacks:
523 it never worked right, and was unnecessary.
524 * Made the `starwars' hack use thicker lines, antialias
525 the text, and fade out at the far edge instead of just
527 * Fixed an SHM segment leak in `moire'.
528 Changes since 3.28: * Better rendering of the new logo.
529 * New hack, `gltext'.
530 * Added `-planetary' option to `gears', to draw a
531 different kind of gear system.
532 * Made motion and rotation be smoother in `gears',
533 `glplanet', `moebius', `rubik', and `sierpinski3d'.
534 * Improved coloration in `sierpinski3d'.
535 * Made the GL hacks react to window size changes.
536 * Made most of the GL hacks take a -fps option (like
537 `pulsar' did), so you can use them to benchmark your
539 * Fixed the previous fix to `sonar'.
540 * Minor fix to `nerverot'.
541 Made sonar able to ping hosts on DEC OSF1.
542 * Eliminated a bogus "didn't get enough colors" warning
543 in some of the hacks.
544 Changes since 3.27: * New logo for xscreensaver!
545 * New hacks, `starwars' and `stonerview'.
546 * Made the motion of the bouncing ball in `stairs' be a
548 * Made newly-added screenhacks be added to .xscreensaver
549 automatically: if there are hacks in the app-defaults
550 file that are not also in ~/.xscreensaver, they will
551 be added to the end of the list.
552 * Redid the `Screensaver Options' part of the control
553 panel; xscreensaver now lets you configure your DPMS
555 * Fixed some Makefile problems with non-GL builds.
556 * Fixed detection of MesaGL for version 3.3.
557 * Better workaround to Red Hat 7.0's broken gcc.
558 * Added Sparc Solaris kernel panic to `bsod'.
559 Changes since 3.26: * New hacks: `zoom' and `whirlwindwarp'.
560 * Fixed a free-memory-reference bug in `sonar'.
561 * Better error handling when there are no suitable GL
563 * Added diagnostic dialog when xscreensaver-demo is
564 unable to launch xscreensaver (e.g., when running as
566 * Fixed a bug that caused screenhack argument changes
567 to be ignored when xscreensaver-demo was running as
568 root (if "root" and "nobody" have different home
570 * Made the programs default to ":0" if $DISPLAY is unset.
571 * Made the `-verbose' output include information about
572 which server extensions were supported at compile time.
573 * Worked around Red Hat 7.0's broken gcc 2.96.
574 * Updated default delays on the GL hacks to look better
575 on machines with super-fast 3D hardware.
576 * Install `screensaver-properties-capplet' to work around
577 the usual egregious GNOME lossage.
578 Changes since 3.25: * Added "enabled" checkboxes in the list of hacks in
579 xscreensaver-demo (Gtk version only.)
580 * New hacks `hyperball', `xrayswarm', and `gflux'.
581 * New versions of `nerverot', `galaxy', and `hypercube'.
582 * Small fixes to `phosphor', `shadebobs', `xflame',
584 * Added external helper program `xscreensaver-gl-helper'
585 to figure out which X visual to use for OpenGL
587 * Configure updates for XFree86 4.0, and for BSD.
588 * Made it be more tolerant of bogus /etc/group files.
589 * When installing the PAM config file, first try to just
590 copy an existing "xdm" or "login" config file, so that
591 xscreensaver does authentication in the same way as the
593 Changes since 3.24: * New hack, `nerverot'.
594 * Added BSD kernel panic to `bsod'.
595 * New version of `shadebobs'.
596 * New version of `petri'.
597 * Updated `webcollage' to handle recent Altavista URL
598 format changes; made it search the AP photo gallery.
599 * Revamped command-line options of `sonar' and made it
600 properly handle subnets.
601 * The `bubbles' hack can now trickle up or down the
603 * The `xsublim' hack can now read its text from programs.
604 * Support for GLE version 3 in `extrusion'.
605 * Fixed compilation problems in `maze'.
606 * Fixed a rare crash in `flow'.
607 * Fixes for minor installation problems.
608 Changes since 3.23: * Added `-ignorant' option to `maze' hack.
609 * Updates to `critical', `bsod', `xflame', and `flow'.
610 * Added support for Kerberos 5 (via its Kerberos 4
611 compatibility layer.)
612 * Fixed a bad leak in `xteevee'.
613 * Updated `webcollage' to handle recent Altavista URL
615 * Removed xscreensaver-demo's `Ok' and `Cancel' buttons,
616 since they were confusing people: all changes are now
618 * Made xscreensaver-demo install itself into the Gnome
620 Changes since 3.22: * Fixed some misplaced text fields in the Motif version
621 of xscreensaver-demo; fixed a crash in the Gtk version
622 that would happen if the programs list was empty.
623 * Fixed a recently-introduced bug in `pulsar'.
624 * Made `sierpinski3d' use solid tetrahedrons instead of
626 * Added `-trace' option to `xmatrix'.
627 * Added new hacks `xteevee' and `xspirograph'.
628 Changes since 3.21: * Fixed some bugs in xscreensaver-demo.
629 * Rewrote the Motif version of xscreensaver-demo to
630 match the new Gtk version.
631 * The Athena toolkit is no longer supported.
632 Changes since 3.20: * Tweaked the xscreensaver-demo UI (Gtk only.)
633 * Fixed a few visual selection bugs. I think the proper
634 GL visual should be used with nVidia systems now.
635 * Made the Makefiles obey $install_prefix.
636 * Made the `xscreensaver.spec' file able to generate both
637 GL and non-GL packages simultaneously.
638 Changes since 3.19: * Added new hacks `ripples' and `sierpinski3d'.
639 * Made `xscreensaver-command -exit' be silent when no
640 screen saver was running (instead of complaining.)
641 * Made `webcollage' and `vidwhacker' use `xloadimage'
642 when available (in addition to `xli' and `xv'.)
643 * Improved memory usage in `petri' and gave it a hard
644 cap on how much memory it can allocate.
645 * Added `-watch' option to `xscreensaver-command'.
646 * Made `xscreensaver-demo' come up with the
647 most-recently-run hack selected by default.
648 * Rewrote the Gtk version of `xscreensaver-demo'.
649 It's a lot easier to use now.
650 * Extended the format of the programs list in the
651 .xscreensaver file, for the benefit of the new
652 capabilities of `xscreensaver-demo'.
653 NOTE: you might want to delete your ~/.xscreensaver
654 file and allow it to be re-created! The old one
655 should still work, but xscreensaver-demo won't be as
657 Changes since 3.18: * Fixed gcc dependencies in `bumps' and `ccurve'.
658 * New hack, `extrusion'.
659 * Some of the web sites that `webcollage' was using as
660 its sources changed formats; tweaked it to understand
662 * Added typeahead in the password dialog: if the screen
663 is locked, and you unlock it by typing a character,
664 that key will be automatically inserted in the
665 password dialog (unless it is Return, Enter, Space,
666 or a non-printing key like Shift.)
667 * Made `xmatrix' take a `-small' option, since some
668 folks with tiny screens prefer a smaller font.
669 Changes since 3.17: * New versions of `shadebobs', `lmorph', and `distort'.
670 * Added `ccurve', `blaster', and `bumps' hacks.
671 * Replaced `forest' hack with a rewritten version.
672 * Worked around a Xinerama server bug.
673 * Fixed a bug I introduced in 3.10 that caused some
674 hacks to print out superfluous warnings about not
675 having gotten enough colors.
676 * Made `sproingies' obey the `-delay' option.
677 * Fixed a portability bug in `shadebobs'.
678 * Made `webcollage' and `vidwhacker' use `xli' in
679 preference to `xv', if it is available.
680 * Added a new source of images to `webcollage'.
681 * If running under KDE, xscreensaver will add itself to
682 KDE's list of screensavers (via xscreensaver.kss.)
683 * Improved detection of GL libraries.
684 * Made the password dialog include the date and time.
685 Changes since 3.16: * New version of `webcollage' -- deals better with
686 corrupted images, and can use an http proxy.
687 * New hack, `xsublim' (run it in the background,
688 rather than adding it to the programs list.)
689 * The xscreensaver daemon was leaking a file descriptor
690 each time you edited your .xscreensaver file. Fixed.
691 Changes since 3.15: * New version of `shadebobs'.
692 * Improved image selection in `webcollage', and sped it
694 * Made configure find the right version of perl.
695 * Rewrote the CGI part of `webcollage'.
696 * `make clean' was deleting some things it shouldn't.
697 * Fixed a typo in the default programs list.
698 Changes since 3.14: * Added `webcollage' and `shadebobs' hacks.
699 * Added a `-stdout' arg to `vidwhacker' so that it can
700 be used in a pipeline.
701 * Made `petri' use less memory.
702 Changes since 3.13: * Various improvements to the Gtk port.
703 * Turned off PAM by default on Solaris, since PAM seems
704 generally to be misconfigured out-of-the-box.
705 * Made the `--without-gtk' configure option work.
706 * Made configure check the Gtk version number, since it
708 * Fixed a bug in the code that attempted to prevent
709 changes of screen resolution while the screen is
711 * Fixed a race condition in `xscreensaver-demo' that
712 could cause an X error at startup.
713 * Added `-transparent' option to `deluxe'.
714 * Added `petri' hack.
715 Changes since 3.12: * Ported `xscreensaver-demo' to Gtk.
716 * Made it possible to build Motif, Gtk, and Athena
717 versions of `xscreensaver-demo' in the same directory
718 without reconfiguring.
719 * Made `xscreensaver-demo' chase symlinks before writing
720 the .xscreensaver file, so that if .xscreensaver is
721 itself a symlink, the underlying file will be replaced
723 * Some Makefile and configure tweaks for Solaris and
725 * Made it possible to set the fire color in `xflame'.
726 * Made transparency work in TrueColor (for `goop' and
728 * Fixed a multi-head bug introduced by the virtual
730 Changes since 3.11: * Made it so that you can't scroll the screen while the
731 lock dialog is up (with XFree86 virtual viewports.)
732 * Fixed a bug in `flag' that caused bob's chin to get cut
733 off after a few iterations.
734 Changes since 3.10: * Made `xjack' be black-on-white-ish, so that it looks
735 less like a computer screen and more like the
736 typewritten paper it's supposed to be.
737 * New version of `pulsar'.
738 * Fixed Solaris compilation problem in `phosphor'.
739 * Made xscreensaver notice XFree86's virtual root window
740 hack, so that if the X server's root window is larger
741 than the monitor's displayable resolution, the screen
742 saver will limit itself to the area that actually
743 appears on the screen.
744 * Made the xscreensaver daemon do a better job of
745 picking the visual class that should be used for GL
746 programs. Less user intervention should be needed
747 now: you can use the logical visual name `GL' instead
748 of having to figure out by hand which one to use.
749 * Oops, the visual was defaulting to "best" instead of
750 "default", because the .xscreensaver file was not being
751 loaded quite early enough.
752 * Made configure figure out how to build icmp ping
753 support into the `sonar' hack automatically.
754 * Made warnings about not being able to read shadow
755 passwords not be printed if compiled with PAM support.
756 * Improved PAM startup diagnostics.
757 * Worked around the Solaris PAM bug that was causing
758 crashes there, so now PAM is turned on by default.
759 * Made configure detect the number of arguments that
760 pam_strerror() takes, since on Linux, this apparently
761 changed between 2.0 and 2.2, sigh.
762 * Made the /proc/interrupts kludge look for "PS/2 Mouse"
763 as well as "keyboard".
764 * Made xscreensaver notice when there has been a sudden
765 large jump in wall-clock time, and if so, lock right
766 away, instead of waiting for "lockTimeout" to expire
767 first. (Laptops need this for safer recovery from
769 * Added `-throttle' option to `xscreensaver-command'.
770 Changes since 3.09: * Added `phosphor', `xmatrix', and `pulsar' hacks.
771 * Fixed a bug in the color allocator that sometimes
772 caused `starfish' to fall back to monochrome.
773 * Reduced the amount of code that runs before root
774 privileges are disavowed: "normal" and "shadow"
775 passwords now do some initialization as root, but the
776 PAM and Kerberos authorization schemes will be
777 initialized while running as "nobody". Supposedly
778 this closes a potential security hole when using
780 * Added some more sanity checking to configure.
781 Changes since 3.08: * Added `compass', `squiral', `xflame', `wander',
782 `spotlight', and `critical' hacks.
783 * Added some new modes to `decayscreen'.
784 * Made `deluxe' work in monochrome.
785 * Generalized usage of the Double-Buffer server extension
786 in several hacks (`compass', `deluxe', `interference',
787 `kumppa', and `moire2'.)
788 * Fixed another visual-depth problem in `rd-bomb'.
789 * The screen saver will now defer blanking if neither
790 the keyboard nor the mouse could be grabbed. Instead,
791 it will just try again in a few minutes. This fixes
792 a bad interaction between xscreensaver and programs
793 like VMware that hold the mouse and keyboard grabbed
795 * Added a new erase mode (expanding spiral.)
796 Changes since 3.07: * Fixed some bugs in my port of `t3d'.
797 * Added `penetrate' and `deluxe' hacks.
798 * When linking against Motif 2.x, also link against XPM.
799 * Added support for using /proc/interrupts for idle
800 detection on Linux. Now xscreensaver shouldn't kick
801 in when the user is active on a non-X virtual console.
802 * Upgraded to autoconf 2.13.
803 Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
804 in properly; check for _Xsetlocale in -lXintl.)
805 * Portability fixes for sonar.c.
806 * Fixed a compilation problem when you have GL but don't
808 * Made configure notice when MesaGL requires -lpthread.
809 * Made `flame' ignore SIGFPE (not sure if this is the
810 right fix; it seems only to be needed on FreeBSD.)
811 * Kludged `rd-bomb' work on visuals that are of depth 24
812 but that *do not* support pixmaps of depth 32.
813 * Fixed `halo' to work properly in TrueColor.
814 * Changed `xscreensaver.spec' to install the hacks in
815 /usr/X11R6/lib/xscreensaver/ by default, since that's
816 where recent Red Hat distributions put them.
818 * Updated versions of `crystal', `hopalong', and `flow'
820 * Imported `demon' and `loop' modes from xlockmore.
821 Changes since 3.05: * Oops, the "default-n" visual descriptor was broken;
822 it was always installing a colormap if the
823 `installColormap' preference was set, meaning that
824 `xearth', `xv' and friends were using the wrong
825 colors on 8-bit systems.
826 * Turned off HAVE_PING in `sonar', since it compiles
827 on some Linux systems, but not others of similar
829 Changes since 3.04: * Fixed an off-by-1 in `distort'.
830 * Added `sonar' hack.
831 * New version of `glplanet' (with stars.)
832 * Made all hacks exit when you type `q' or `ESC' at them,
833 and made them obey the WM_DELETE_WINDOW ClientMessage.
834 * Fixed a nonfatal buffer overrun in lament (note:
835 lament still doesn't work with MesaGL 3.0: it dies in
836 lambda_textured_triangle1(), which is Mesa's bug, not
838 Changes since 3.03: * Added an `xscreensaver.spec' file, to make it easier
839 for other folks to generate RPMs.
840 * Made the password code work on HPUX in the situation
841 where: ``enhanced security'' is available; but not
842 used; but the user typed a password more than 8
843 characters long anyway. FTSOHPUX.
844 Changes since 3.02: * Made locking work when passwd aging is enabled.
845 * Added support for PAM (Pluggable Authentication
846 Modules.) It is still turned off by default, though,
847 since it doesn't seem to work on Solaris 2.6, and has
848 been behaving erratically on Red Hat 5.1.
849 * Made each possible authentication method be tried in
850 turn until one succeeds; this means that Kerberos is
851 being used, we will first check Kerberos, and if that
852 fails, will then consult the local password file.
854 * Save and restore the bits under the passwd dialog,
855 to avoid leaving a black rectangle behind when
856 unlocking is cancelled.
857 Changes since 3.01: * Not everyone has sys/select.h, sigh...
858 Changes since 3.00: * Some fixes to `reflect'.
860 * Made it log unsuccessful attempts to unlock the screen
862 * Fixed a bug where `xscreensaver-demo' could be seeing
863 a different programs list than `xscreensaver' did.
864 Changes since 2.34: * The xscreensaver daemon no longer links against Motif
865 or Athena: demo-mode and the preferences panel are no
866 longer built in to the daemon, but are now handled by
867 an external program, `xscreensaver-demo'.
868 (I decided that this, along with the recent addition
869 of the `.xscreensaver' config file, justified bumping
870 the version number to 3.00, since this is a fairly
871 major architectural change.)
872 * Lines in the `*programs' resource may now begin with
873 the character "-", meaning "don't run this hack."
874 In this way, it's possible to disable a hack without
875 throwing away the information about it (making it
876 easier to change your mind later.) Eventually the
877 preferences/demo mode GUI should represent this as a
878 checkbox or something.
879 * Fixed a short race condition where it was possible for
880 xscreensaver to die with a BadWindow error if it was
881 blanking the screen just as another window was being
883 * Made it possible to disable specific modes in `bsod'.
884 Changes since 2.33: * Fixed a bug that was making `pipes' generate way too
885 many valves. Made the viewpoint in `pipes' be selected
886 randomly instead of always being -10 degrees.
887 * Fixed a bug in the XSHM code, in the case where the
888 server supports the XSHM extension but is not the same
889 machine as the client.
890 * Made `rd-bomb' default to taking up the whole screen.
891 * Made it not try to do fading/unfading if no PseudoColor
893 * Initial attempt at supporting VT-locking (doesn't work
895 * Eliminated the `captureStdout' resource; now
896 `captureStderr' controls both streams.
897 * Added `-capture-stderr' and `-no-capture-stderr'
898 command-line arguments.
899 * Added `glplanet' hack.
900 * When a hack is selected with `xscreensaver-command
901 -select', that hack will be used until further notice
902 (until the saver turns off, or another activation
904 Changes since 2.32: * Made `xscreensaver-command' print error messages:
905 the xscreensaver daemon now responds to ClientMessage
906 events by writing a response message on a window
907 property, instead of just writing to its stderr.
908 * Made the ~/.xscreensaver file be automatically reloaded
909 when the file date changes.
910 * The password dialog and splash screen no longer depend
911 on Motif or Athena. This should clear up a number of
912 focus problems, and is the first step on the path
913 toward moving all of the Motif/Athena/whatever code
914 out of the xscreensaver daemon, and into external
916 * Don't complain about LessTif 0.86 any more, since the
917 new password dialog makes that problem go away.
918 * Configure tweaks for Irix 6.5, SunOS 5.something.
919 * New `-reflect' option to `distort'.
920 Changes since 2.31: * Added reading and writing of a ~/.xscreensaver file,
921 so that the Preferences panel can save its settings.
922 * New version of `rubik'.
923 * Added `-select N' argument to `xscreensaver-command'.
924 * Oops, left out some of the `bubbles3d' files...
925 Changes since 2.30: * The cursor was invisible in the password dialog. Fixed.
926 * Made configure warn against MesaGL 2.6.
927 * Fixed X error at startup when using non-default visual.
928 * New version of `crystal', `ant', and `atlantis' from
930 * New hack, `bubble3d'.
931 * Added some new modes to `bsod'.
932 Changes since 2.29: * Changed the order in which -lSM and -lICE are linked
933 to be after Motif instead of before (Lesstif on Irix
935 Changes since 2.28: * Work around a bash bug in configure.
936 * Tweaked HPUX paths again. FTSOHPUX.
937 * Made configure recommend against LessTif 0.86, due
938 to a bug in that version that causes a security hole
939 in the screen locking code. LessTif 0.87 will fix it.
940 * Made all of the `--with' options to `configure' accept
941 a directory option as well (so that --with-motif=/FOO
942 will add -I/FOO/include -L/FOO/lib). I believe this is
943 the Configure Party Line of how do to such things.
944 * Fixed a bug where the mouse was left un-grabbed
945 after the first time the graphics hack was changed
946 (simplified all of the mouse-grabbing logic.)
947 * Maybe possibly perhaps made `vidwhacker' really not
948 leave stray xv windows around. This time for sure.
949 * Added a new erase mode (random dots fizzling out.)
950 * Added `-prefs' argument to `xscreensaver-command',
951 that brings up the Preferences dialog directly (it
952 seems that nobody ever noticed the `Preferences' button
953 on the Demo Mode dialog, maybe this will help.)
954 * Added a splash screen. Turn it off with *splash:false.
955 Changes since 2.27: * Better macsbug text in `bsod'.
956 * New version of `distort' with many new modes.
957 * Plugged a leak in `coral'.
958 * Tweaked configure for HPUX.
959 * Removed some compiler warnings.
960 * More consistent usage of stderr versus stdout.
961 * More diagnostics should an X error occur.
962 * Fixed a possible crash in SGI-specific unfading code.
963 Changes since 2.26: * Improved version of `distort'.
964 * Made `lament' compile against OpenGL 1.0 (though it
965 still requires 1.1 to work properly.)
966 * Updated my email address and home page.
967 Changes since 2.24: * Improved motion in `rd-bomb'.
968 * Added XSHM (shared memory extension) support to the
969 `distort', `interference', `moire', `rd-bomb', and
970 `swirl' hacks, which speeds them up a bit.
971 * Added `lament' hack.
972 Changes since 2.23: * Tweaked the order of the -L options again.
973 * Cleaned up configure's `--help' message.
974 * Added `kumppa' hack.
975 * Smarter maze-solving algorithm in `maze'.
976 * Took `xlyap' out of the default list of hacks, since
977 it's just incredibly buggy (and slow.) Maybe someday
978 someone will fix it...
979 * Added `distort' hack, but didn't add it to the default
980 list (yet) because it's still too slow.
981 * Made the Athena demo dialog look more like the Motif
982 version; it has a text-entry field now, too.
983 * Made the Athena password dialog echo asterisks, like
984 Motif does, instead of using a flyspeck font.
985 * Some random configure tweaks.

991 Changes since 2.21: * Added support for the DPMS server extension (Display
992 Power Management System.)
993 * Made configure advertize the `--enable-subdir' option a
994 little more, since that seemed to cause some people
995 stress. Also, made that directory be built into the
996 xscreensaver executable, as a hardcoded prefix to
997 $PATH. (Might help, shouldn't hurt.)
998 * Made configure prefer the two-arg gettimeofday to the
999 one-arg version, since AIX doesn't have any prototypes.

1008 "active since..." and "inactive since..." which a lot
1009 of people interpreted as meaning the opposite of what
1011 * Improved some error messages, in the hopes of making
1012 the distinction between the xscreensaver and
1013 xscreensaver-command programs more obvious.
1014 * Rewrote (and reorganized) parts of the xscreensaver and
1015 xscreensaver-command manual pages.
1016 * Renamed xscreensaver's `-lock' command-line option to
1017 be `-lock-mode', to avoid confusion with the `-lock'
1018 option to xscreensaver-command, which does a totally
1020 * Removed xscreensaver's `-demo' command-line option for
1021 a similar reason; use `xscreensaver-command -demo'
1023 * Disabled SGI's ``scheme'' nonsense in a better way than
1024 fully-qualifying the background colors in every single
1026 * Fixed some other minor cosmetic problems when *sgiMode
1028 * Fixed an X error in `bsod -root' (how ironic...)
1029 Changes since 2.19: * Fixed a bug that caused the mouse to sometimes not be
1030 grabbed properly (meaning the window manager menu could
1031 pop up over the demo-mode display.)

1044 * Added `truchet' hack.
1045 * Added `bsod' hack.
1046 * Added some new modes to `vidwhacker'.
1047 Changes since 2.16: * Added a -window-id argument to most hacks, so that they
1048 can draw on arbitrary externally-provided windows.
1049 * Synched with xlockmore 4.11a01.
1050 * Added `flow' hack.
1051 * Added `atlantis' GL hack.
1052 * Renamed `puzzle' hack to `jigsaw', since xlock already
1053 had a different mode called `puzzle'.
1054 * Made it self-configure properly when Motif 2.1.0 is
1055 being used (requires -lXp now, sigh...)
1056 Changes since 2.15: * Made `flag' able to do XPM images.

1070 * Split `escher' into `cage' and `moebius', as per
1072 * Changed subprocess handling to use sigaction() instead
1073 of signal() if it's available (this is necessary for
1074 SCO but should work fine on other systems too.)
1075 * Various other tweaks.
1076 Changes since 2.13: * Better fix for the Motif drag-and-die lossage.
1077 * Put in some kludges to work around a LessTif bug.
1078 * XScreenSaver is known to work with LessTif 0.82 now.
1079 * Made fading work on high-end SGI video hardware.

1093 * Fixed a buffer overrun in the locking code that some
1094 wily, malicious cracker must have slipped in.

1099 * Added `puzzle' hack.
1100 * Added `xlyap' hack.
1101 * Added `default-n' as a visual name, so that one can

1103 certain poorly-behaved hacks (like xv.)
1104 * Added support for grabbing frames of external video
1105 (on SGI) to the screen-grabbing hacks (decayscreen,
1106 slidescreen, slip, blitspin, and puzzle.)
1107 * Improved look of tiles in `slidescreen'; fixed its
1108 color allocation problem.
