dmesg output

Hardware:
Asus K53TA laptop. AMD A6-3400M with integrated Radeon HD6520G and discrete
Radeon HD6650M. Display is through 6520G.

Software:
Ubuntu 11.04 64 bit with kernel 3.2-rc1 and xorg-edgers ppa.

When I start teeworlds, the screen goes blank (the display seems to be switched
off). However I am able to switch to command line using Ctrl + Alt + F1 and
running:

sudo service gdm start 

and 

sudo service gdm stop

restarts Gnome for me.

dmesg shows some errors with atombios.
