Try booting with the vesafb.anything=1 kernel parameter.

Bryce,

I tried with the parameter on 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.

Interesting; the error message on the screen about nouveaufb conflicting with VESA VGA seems to indicate a conflict with a framebuffer driver (vesafb seems likely - we're seeing a lot of bugs related to that such as bug #702090)

Yeah, give the -3 kernel a try.

RAOF, any ideas? Is next action for this to forward upstream or is there more debugging that can be done on this end?

The interesting part of the kernel log contains:

It looks like nouveau is failing to find any acceptable modes. Since this is a laptop, that probably means that it's unable to find an LVDS mode, either in the VBIOS, by ACPI, or via EDID.

Upstream will probably want a vbios dump - you can get that with “sudo cat /sys/kernel/debug/dri/0/vbios.rom > ~/vbios.rom”

It would also be nice to get dmesg a boot with drm.debug=0xe, to have the most possible useful debugging info.

Once we've got those things this should be sent upstream.

I think the vesafb thing is not a part of the problem, although upstream will probably complain about it :(.

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.

Hi Alex,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Alright, as per comment #11 it sounds like the original issue is gone (and probably was a kernel drm issue). The user is still experiencing gpu lockups, but this is already covered by bug #553789.

Fwiw, we will need to get better GPU hang tools for -nouveau in place before we can effectively diagnose GPU lockups with that driver. Meanwhile, work directly with upstream or with the Ubuntu kernel team on them (since GPU hangs are almost always due to issues in kernel drm).

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,
