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

--- Comment #4 from Alex Deucher agd5f@yahoo.com --- Make sure your kernel has this patch: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=22...
You can also try disabling tiling in your xorg config:
Section "Device" Identifier "Radeon" Driver "radeon" Option "ColorTiling" "true" Option "ColorTiling2D" "true" EndSection

--- Comment #5 from bz@yotm.com --- 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.

Sorry, logic inversion. try this:
Section "Device" Identifier "Radeon" Driver "radeon" Option "ColorTiling" "false" Option "ColorTiling2D" "false" EndSection

Is this a bug?
Yes. I need to sort out what's wrong with tiling on your board.

--- Comment #9 from bz@yotm.com --- 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.
