Binary package hint: xserver-xorg-video-ati
Sometimes the internal laptop display (LVDS) goes off (like a DPMS standby) for no reason (there is user activity going on).
Moving the mouse or typing on the keyboard makes the screen turn on again (no password request or user logout happens)
This happens on a fully updated Karmic with a mobility radeon X700 using the standard radeon driver.
