Public bug reported:

Hello,

I have an AMD R9 270X graphics card and Ubuntu will occasionally go into
"low-graphics mode" when starting up. At that point I cannot do anything
apart from drop into the terminal.

It happens sporadically, about 3/4 of the time. Often a reboot will fix
it however because it happens so often, it's very annoying.

I've tried installing fglrx and fglrx-updates along with the latest
proprietary AMD drivers including 14.4 stable and 14.3 beta. However it
still occurs.

I've also tried using failsafeX settings among other things without
success.

Attached are the Xorg and Xorg.failsafe log files.

There's a segmentation fault at the bottom of the failsafe log files
which may have something to do with it?
