Cannot log in after fglrx update (15.201-0ubuntu0.14.04.1)

[Otus]

After updating to the newest version of the fglrx package (15.201-0ubuntu0.14.04.1) I can no longer log in after a reboot. When I type a password it takes a couple of seconds to throw me back into the log in screen. Previous versions worked fine.

Removing fglrx to switch to the free drivers solved any log in problems. Reinstalling fglrx introduced them again.

I haven't debugged beyond that, but I can in the next few days if given instructions.
