Description Bryce Harrington 2009-05-05 13:18:25 UTC
Forwarding this bug from a Ubuntu reporter:

With UXA, when I load up Xorg I may or may not see corrupted images on my screen. However, no matter what, half a second later, the screen goes black and I can't Alt+Ctrl+F<n> to a command prompt.

I'm using an Intel 945GME Express [8086:27ae] (rev 03).

Hi, I'm the original reporter.
Comment 5 Jesse Barnes 2009-05-11 11:21:24 UTC
Adjusting severity: crashes & hangs should be marked critical.
Comment 6 Eric Anholt 2009-05-12 15:15:11 UTC
UXA never worked on non-GEM kernels until after 2.7.0.  Please try, which includes a series of fixes that got it working for me.
Comment 7 Carl Worth 2009-06-03 10:18:02 UTC
As Eric says, this should be resolved with more recent versions of the driver. Please feel free to re-open the bug report if you upgrade and still have problems.
