--- Comment #1 from Thomas Rohloff v10lator@myway.de --- I tried the Effects Cave Demo on a Radeon HD 6950: After it loaded the sound played but the screen was going into standby and the system wasn't even reacting to MagSysRq keys. Would love to give logs but they where wiped with the system reset.
