Picture of corrupted screen

Hello,

When booting Ubuntu Trusty daily the desktop and all further screens are
corrupt. The loading screen displays correctly. The mouse/pointer still works
and displays correctly. Switching to a tty also works and displays correctly.

Booting Ubuntu Precise (live) works correctly.

Regards,
Tim

Make sure your kernel has this patch:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=227ae10f17a5f2fd1307b7e582b603ef7bbb7e97

You can also try disabling tiling in your xorg config:

Section "Device"
    Identifier "Radeon"
    Driver "radeon"
    Option "ColorTiling" "true"
    Option "ColorTiling2D" "true"
EndSection

Hello,

The kernel I was using was 
Linux ubuntu 3.13.0-8-generic #27-Ubuntu

That patch you mention made it to #28, I have since tested with the updated
kernel and the xorg.conf options you mention, neither have resulted in a fix.

Regards

Sorry, logic inversion.  try this:

Section "Device"
    Identifier "Radeon"
    Driver "radeon"
    Option "ColorTiling" "false"
    Option "ColorTiling2D" "false"
EndSection

Yes.  I need to sort out what's wrong with tiling on your board.

Do you have access to a similar card? I can send you mine if you like, as I
have a spare HD5450 I can use in the interim.
