I set my screen saver preferences with
xset dpms 600 900 1200
However, the slightest bump against the desk causes unwanted deactivation of
the screen saver. Is it possible to increase the amount the mouse has to
move to deactivate the screen saver? Alternatively, is it possible to
disable mouse movement completely as a screen saver deactivation causing
event (so that only a key press deactivates)?
