I wonder what that is and what causes it?

I tried adding this to xorg.conf:
Option "Ignore" "true"
Xorg fails to initialize with the "no screens" error (monitors were
found but none has a usable configuration). I also tried 'xrandr
--output LVDS --off', but the DVI-0 output remains blank. Any other way
I can disable LVDS?

Added this option under the device section of the radeon driver. Same
