Try disabling the screen saver and/or DPMS (energy saver) via the xset command. To see what your current settings are, type 'xset q' To disable DPMS, type 'xset -dpms' To disable the screen saver, type 'xset s off' Note: these settings will not persist after you quit your current session or reboot the machine. Hope this gives you a starting point.
