`xss` uses the nearly 20-year-old MIT-SCREEN-SAVER extension to launch a
|
|
program when the X server turns on the built-in screen saver.
|
|
|
|
`xsswin` makes a full-screen black window and runs some other program,
|
|
passing along the window ID in the environment (`$XSS_WINDOW`) and
|
|
possibly as an argument (`XSS_WINDOW` in argv is replaced with the ID).
|
|
|
|
`xkeygrab` grabs the keyboard and mouse, and echoes all typed lines to
|
|
stdout.
|
|
|
|
`xcursorpos` prints out the x and y coordinates of the cursor.
|
|
|
|
`magic` is a reimplementation of the "magic" screen saver from After
|
|
Dark. It probably doesn't work with an 8-bit color pallette.
|
|
|
|
|
|
Examples
|
|
--------
|
|
|
|
Tell the X server to launch the screen saver after 90 seconds idle:
|
|
|
|
xset s 90
|
|
|
|
|
|
Run like `xautolock`:
|
|
|
|
xss xlock -mode qix &
|
|
|
|
|
|
Shell script to run `magic` while waiting for a pass word from the keybord. Won't
|
|
do anything if the cursor is in the upper-left corner:
|
|
|
|
#! /bin/sh
|
|
|
|
xcursorpos | (read x y; [ $x -lt 20 -a $y -lt 20 ]) && exit 0
|
|
xsswin magic XSS_WINDOW &
|
|
pid=$!
|
|
xkeygrab | (while read l; do [ "$l" != "secret" ] && break; done)
|
|
kill $pid

History
|
|
-------
|
|
|
|
AIX apparently had something also called `xss` which did almost exactly
|
|
what mine does, but with command-line options.
|
|
|
|
`magic` is similar to the `qix` hack from xscreensaver and xlock.
|
|
|
|
I'm not aware of anything else like the rest of the programs, which is
|
|
why I wrote them.
|
|
|
|
I lifted some code from `beforelight` from the X11 distribution, and
|
|
from `slock` from [suckless.org](http://suckless.org/). Both have a
|
|
BSD/X11-like license.
