I have X running on the cubieboard2 and all is in happiness except after 10 minutes
the screen blanks and neither the keyboard nor the mouse will bring it back to life.
I am just starting X with startx and running a single xterm with twm.
I have used
xset -dpm
xset s off
xset s noblank
Do I need anything else ? and where can I set this up to
be applied when X starts ?
