http://ubuntuforums.org – With 12.04, I'm running a Sansung external monitor (digital connection via DisplayPort) from Thinkpad x220, and periodically the screen goes black for a half-second or so. This is unpredictable but happens often enough to be annoying. Any thoughts on what may be happening? (Hardware)
