== A == Things that _do_ work on sec. (hdmi) monitor: * playing video streams in browser * 3D games (openarena) * 2D games (wesnoth) == B == using mplayer has same symptoms as vlc player has plus sound get laggy and finally dies off == C == When I move the vlc/mplayer video window torwards the hdmi display until I notice misbehaviour (which happens as soon as more than 50% of the video window are visible on hdmi monitor) I pull it back to the laptop's monitor. That "pulling back" is only visible after a long delay (30 Seconds - 1 Minute) but after that the computer is recovered and proceeds to work as expected.
