[Problem]
The internal display is distorted with vertical bands of different colors separated by black and white noise.  This worked in Ubuntu 11.10 (kernel 3.0).

The  the good news is that an external monitor now works perfectly through the mini displayport, which did not work in Ubuntu 11.10.

The background is supposed to be a purple gradient (ala https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/898784/+attachment/2616711/+files/Screenshot%20at%202011-12-02%2017%3A17%3A49.png)

Comment 4 Peter Hedlund 2012-02-15 17:23:00 UTC

Since this is a regression I am interested in trying to walk backwards to try to identify the problem. Is it likely that the problem is in xf86-video-nouveau or someplace else? Is cgit.freedesktop.org down or where do I browse the code? I would appreciate any hints on how to go about this.

Comment 5 Peter Hedlund 2012-03-20 10:48:48 UTC

Fixed for me in linux kernel 3.3.

Comment 6 Maarten Lankhorst 2012-06-28 04:38:02 UTC

Fix is backported from 3.5rc to 3.4.3 and 3.2.21
