An [Acronym] for __D__isplay __P__ower __M__anagement __S__ystem.

Allows a monitor to change its power usage state to Standby, Suspend, and Off.

If you have a new enough monitor, you can use the xset(1) command to change the default timeouts.

''Make sure you have the line
 Option "DPMS" "1"
in your /etc/X11/XF86Config file, in the Monitor section''

 $ xset q
 ...
 ...
 Bug Mode: compatibility mode is disabled
 DPMS (Energy Star):
   Standby: 7200    Suspend: 7200    Off: 14400
   DPMS is Disabled
 Font cache:
   hi-mark (KB): 1024  low-mark (KB): 768  balance (%): 70
 $ xset +dpms
 $ xset dpms 300 600 900

"xset q" shows the current status. (It says disabled). "xset +dpms" enables dpms. The last command says "go into Standby mode after 300 seconds without user input, Suspend mode after 600 seconds, and Off after 900 seconds".

If you want your moniter to turn off right now (eg: You don't want it glowing at you while you're trying to sleep) try
 xset dpms force off
