Disable screensaver / screen blank via command line?

Solution 1:

You can use the xset command to disable screen blanking and locking.

E.g.

xset s off (turns off the screen saver)

xset s noblank (turns off blanking)

You can also use it to disable the power management using dpms to power the monitor down

xset -dpms

I use these commands in a script set to run at login to stop the screen blanking on my MythTV machine.

EDIT:

Script I mentioned:

#!/bin/sh
export DISPLAY=:0.0
xset s off
xset s noblank
xset -dpms
