Description Bryce Harrington 2011-02-16 20:02:58 UTC 
Forwarding this bug from Ubuntu reporter Alex Mayorga Adame:
http://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/713781

[Problem]
Starting with 2.6.38-1, user reports X on -nouveau becomes corrupt (see attached screenshot).  This is a regression since 2.6.37-12

We had the reporter disable vesafb in case it was conflicting, but issue persisted.

Our guess is it looks like nouveau is failing to find any acceptable modes.

[Original Description]
Latest kernel update rendered X unusable.

I tried both 2.6.38-2 and 2.6.38-1 kernels but it didn't help. It still shows the progressive line of pixels.  gdm and the desktop actually load as I can hear the Ubuntu tune if I type my password and hit enter but the video is garbled and only a line of pixels towards the top of the screen can be seen.

2.6.37-12 works fine with no parameters and even some degree of video acceleration.

Bugzilla says the screenshot is too big to attach, but it's in launchpad here:

Comment 8 Ilia Mirkin 2013-08-18 18:10:15 UTC 
It appears that this bug report has laid dormant for quite a while. Sorry we haven't gotten to it. Since we fix bugs all the time, chances are pretty good that your issue has been fixed with the latest software. Please give it a shot. (Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git versions.) If upgrading to the latest isn't an option for you, your distro's bugzilla is probably the right destination for your bug report.

In an effort to clean up our bug list, we're pre-emptively closing all bugs that haven't seen updates since 2011. If the original issue remains, please make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/ for what we need to see, and re-open this one.

Thanks,

The Nouveau Team
