usual usage(time in minutes, 0-60):
xautolock -time 1 -locker "xset dpms force off"

with current compile:
(because I put "xset dpms force off" in source as default "locker"
xautolock -time 1&

(see locker.diff)

ALSO:
adds the script 
/usr/local/bin/set_screen_timeout

and icon
/usr/share/pixmaps/timer.svg
