Changed /etc/X11/xorg.conf

In the "ServerLayout" section I added the following:

Option "BlankTime" "0"
Option "StandbyTime" "0"
Option "SuspendTime" "0"
Option "OffTime" "1"

OffTime 1 minute makes the screen go black after a minute of inactivity.
In my application I tickle the screen once every 10 minutes with the  
following lines:

echo 0 > /sys/class/graphics/fb0/blank
echo 1 > /sys/class/graphics/fb0/blank

This works ok, but I don't know why. I don't get WSOD anymore and that's  
the most important thing. If someone have a clue I'd be happy to know.
