Bug Description
The PC has a Llano A6-3650 APU with a display connected to the VGA port, but the display turns off when plymouth should appear, thus making installation from liveCD/USB impossible. Ubuntu starts up, as I can hear the login sound, but nothing is visible.
Filed separately, as requested in bug #825777, as this one is about a PC, and the other one is about laptops.

dmesg log of radeon errors
I have an ASRock A75M motherboard with an A8-3850.
Booting a 3.1 kernel (also tried 3.06), my screen goes blank with modesetting enabled. If I disable modesetting, I am able to boot fine but then X won't work because the X11 driver requires modesetting.
