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
