When booting up, LightDM has a very low display resolution.
Further investigation shows, that X is mirroring VGA-0 output to the DVI(reported as HDMI-0 by xrandr) connector.
So DVI ends up having the wrong display resolution, because X believes VGA-0 has a display being connected to it supporting 1024x768/800x600 only, which is wrong.
See attachment "xrandr_after_login.txt" for Output of xrandr after logging in and gnome/unity applying correct resolution and manually switching of VGA-0.
I am running Ubuntu 11.10 beta2 x86_64 with an "AMD A6-3500 APU with Radeon(tm) HD Graphics" on a MSI A75MA-G55 board.

Thank you for taking the time to file a bug report on this issue.
However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.
We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.
If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.
Thank you for your help, we really do appreciate it.
