You could edit /etc/X11/xork.conf and in the section labelled "ServerLayout" set

Code: Select all

    Option "BlankTime" "30"
    Option "StandbyTime" "60"
    Option "SuspendTime" "65"
    Option "OffTime" "120"


or some combination of parameters. Restart X for changes to have an effect.

See http://www.x.org/archive/X11R6.8.0/doc/xorg.conf.5.html

You can also control the X server options as a user while X is running using the xset command.
