-To build:
+ XScreenSaver
- - read the comments in `config.h' and edit it as appropriate
- - xmkmf ; make
- - make install install.man
+ a screen saver and locker for the X window system
+ by Jamie Zawinski
+
+To build on Unix:
+
+ - ./configure
+ - make
+ - make install
+
+The `configure' shell script will attempt to figure out which options are
+appropriate for your system, and will create config.h and the various
+Makefiles for you. Run `configure --help' to see how to override these
+choices, or to specify things like the default installation directory.
+The file `INSTALL' gives a general overview of use of these sorts of
+configure scripts (those generated by the GNU autoconf system.)
+The most important hint is probably this:
+
+ ./configure --includedir=/opt/Motif/include --libdir=/opt/Motif/lib
+
+To build on VMS, see README.VMS.
+
+ ============
The xscreensaver program waits until the keyboard and mouse have been idle
for a period, and then runs a graphics demo chosen at random. It turns off
are being run as screensavers don't need to have any special knowledge
about what it means to be a screensaver.
-The XIDLE or MIT-SCREEN-SAVER server extensions will be used if you have them.
+The XIDLE, MIT-SCREEN-SAVER, and/or SGI SCREEN_SAVER server extensions
+will be used if you have them.
-Unfortunately, locking doesn't work if you don't have Motif.
+The dialog boxes (for locking and demo-mode) look best using Motif, but
+can be configured to use Athena widgets instead.
Also included are several graphics hacks for use as screensavers. There's
nothing magic about these: they're just programs that draw on the root
maze - This is the X maze demo modified to take a -root option
so that it works with xscreensaver.
lmorph - morphing line drawings.
+ bubbles - condensation forms on your monitor, then pops.
+ deco - Generates Brady-Bunch-era wall paneling.
+ moire - Circular interference patterns.
+ kaleidescope - Groovy, man.
+ swirl - Swirly color-cycling patterns.
+ bouboule - Spinning bubbles on a transparent ball.
+ braid - Draws random color-cycling braids around a circle.
+ drift - Drifting recursive fractal cosmic flames.
+ fract - Small, curvy geometric patterns.
+ galaxy - Spinning, colliding galaxies.
+ grav - Orbital simulation and/or cloud chamber.
+ ifs - Spinning, colliding iterated-function-system shapes.
+ julia - Animated rendition of the Julia set.
+ laser - Moving radiating lines.
+ lightning - Crackling fractal lightning bolts.
+ penrose - Quasiperiodic tilings.
+ sierpinski - two-dimensional Sierpinski triangle.
+ slip - Sucks your desktop through a jet engine.
+ spiral - Circular color-cycling interference patterns.
+ strange - Animating strange attractors.
+ flag - A waving flag of an arbitrary bitmap or text.
+ sphere - draw a bunch of shaded spheres.
+ forest - grows a fractal forest.
+ lisa - draws animated full-loop lisajous figures.
+ goop - Squishy transparent oil-and-bubble images
+ starfish - Radially-symmetric throbbing colormap-hacking blobs.
+ munch - The classic 1962-vintage "munching squares" hack.
+ fadeplot - Draws a swimming ribbon.
+ escher - Draws some escher-like scenes (GLX only.)
+ gears - Draws interlocking rotating gears (GLX only.)
+ morph3d - Draws shiny shape-changing 3d forms (GLX only.)
+ superquadrics - More shiny shape-changing 3d forms (GLX only.)
+ pipes - Generates a field of intertwined plumbing (GLX only.)
+ rubik - Solves a Rubik's Cube (GLX only.)
+ sproingies - Marble Madness meets Q-Bert (GLX only.)
All of these will pop up their own window unless given that -root option.
See their man pages for more details.
xswarm -r 2>&- - swimming sperm
xwave -root - random 3d graphs
xbouncebits - bounce arbitrary bitmaps around
- ico -r - it's dull, but it's there
+ ico -r -p8 -faces -sleep 1 - it's dull, but it's there
xv -root file.gif -quit - they don't all have to animate!
xsplinefun - bouncing splines
- kaleid -root - qix-like kaleidescope patterns
xfishtank -c black -d -r 1 - fish (use version 2.0 or later)
+ xtacy -root - various eye candy
+ /usr/demos/bin/bongo -wbongo - an SGI GL demo
You can get all of these from the contrib directory on ftp.x.org. If you
know of (or write) any other interesting programs that can be used as
screensavers, please let me know!
