X has built-in monitor power management, but it usually gets disabled by 
a desktop environment power manager program, since they like to control 
things themselves.

But if you're not running a desktop environment, to control the power 
settings with X, man xorg.conf and look for DPMS.  You can add something 
like this to your xorg.conf file:

Section "ServerFlags"
     Option "BlankTime" "0"
     Option "StandbyTime" "0"
     Option "SuspendTime" "0"
     Option "OffTime" "0"
EndSection
