--- Comment #28 from Alex Deucher alexdeucher@gmail.com 2012-08-25 13:05:38 --- If it works with 3.1.0-1.2 can you bisect against something newer that doesn't work to identify what commit broke things for you? Also please attach your xorg log and dmesg output with KMS enabled and a picture of the problem.
