<pre>I updated my driver yesterday to the latest provided by
ppa:oibaf/graphics-drivers, and now I'm having having problems with on of the
monitors attached to my (r7 260x) card.
Snippet from

If you look in the dmesg log, there is also mention of:
*ERROR* atombios stuck in loop for more than 5secs aborting
My computer did lock up until I installed the latest mainline kernel, but the
error still remains. This may be related to
