[AMD/ATI] Cedar HDMI Audio [Radeon HD 5400/6300/7300 Series] Some times the problem starts with 2 screens from one graphics board switching to standby and the mouse can only use 2 screens. Sometimes I cant click into shell windows to get focus. The Problem ends with a locked console, so I can see the other processes of the guest machines perfectly running, but can not enter anything or move the mouse. If I press the power button the dialog for shuting down the machine appears, but it does not help, as I cant click. !! Feature request: toggle through the power-button induced shutdown menue by shortly pressing the power button again (catch the event and see if the menue is already active), and select the option by pressing the power button shortly 5 times within 4 seconds. /feature request. But it would be higher to solve the problem, as it is quite anoying. How to debug? It is quite random. Cheers.
