screen blanking (was: Recommendations...)

[Michael ODonnell]

Blanking can be a builtin function of your desktop, a separate
screensaver app or maybe even your X server.  Try connecting via
SSH while the screen is blanked and use ps to see what's running
to get an idea of likely suspects.

Also, have a look in your X config file (probably /etc/X11/xorg.conf)
and see if anything related to blanking is mentioned there; if a DPMS
option is enabled you might try commenting that out and restarting X.
