[drm:radeon_atom_pick_dig_encoder [radeon]] *ERROR* chosen encoder in use 0

It appears you are using the unsupported 'oibaf' PPA for your Mesa files. Please remove the PPA from your system and retest.

Adding this PPA and switching to Mesa was my try to resolve bug. Without this it was the same problem. I can revoke PPA no problem.

After you have removed the PPA and rebooted, if the problem still occurs then please open a new bug by running:

   ubuntu-bug linux

and then we can make this a duplicate of that new one.
