Public bug reported: The problem is this: I have an HD5770 card with 3 screens connected, 1 monitor to DisplaPort-0 and 1 monitor to the DVI-0 and a TV to the HDMI-0
When I turn my tv on the screen connected to displayport immidiately goes black and it says "no signal". To wake this screen again i need to issue the command "xset dpms force suspend" This will wake the screen connected to the displayport. The same thing also happens when I turn the tv off again. How it should work and has worked before: I should be able to turn my tv on and off without it interfering with my other screens. I have pinned this regression down to happen in the kernel 3.0.3 found here http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.0.3-oneiric/ But it is alright in the kernel 3.0.2 found here http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.0.2-oneiric/ This is the changes made between 3.0.2 and 3.0.3 that i think has something to do with my problem.
