Same issue on Ubuntu 13.10

This happens on both Ubuntu 13.10 Unity, and Ubuntu GNOME. It use to happen on Kubuntu, but the ".config" settings have solved it. No more gliches on Kubuntu 13.10 at all.

With Ubuntu 13.10 Unity, the Launcher and Panel are "rainbow" colored and completely cover up Launcher & Panels. The background is normal. The Launcher flashes for a breif second so I see the icons, but then the "rainbow" color covers it up.

With Ubuntu 13.10 GNOME, it is random when it freezes. I can ALWAYS cause it to freeze if I start Empathy. Various programs can cause it to freeze but not always. Empathy will always freeze the computer, and cause the screen to have unrecognizable virtical lines. A power off is the only option, That "elephant" nonsense doesn't work here.

I know its the "GeForce 6150SE nForce 430" graphics that's causing this, because if I use "nomodeset" nothing freezes.
With Kubuntu, when it first started freezing, I could use "modeset=0" and it would work.

I can confirm this bug affects my computer using nvidia and ubuntu gnome 13.10 (random visual artifacts and freezes). This does not happen on another computer using intel graphics card. This is very annoying because I can't install the drivers from nvidia, if I do my computer hangs while starting up, showing a black screen.

Please vmclark, can you copy here the .config settings for Kubuntu (an tell me what .config file is)?

Thanks

Actually using Kubuntu. All I have to do is use nomodeset on first boot after install. After that it boots normally without it.

This nouveau bug is present on 14.04 testing, on each daily install.

Tong Sun, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xserver-xorg-video-nouveau REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

Thank you for your understanding.

Christopher, I downloaded today's ISO from dev-branch, but it was impossible to complete the command:

apport-collect -p xserver-xorg-video-nouveau 1181902

because I can't even start Ubuntu from graphic mode. When I click on "Preview Ubuntu" (rather than Install) I switched shell (Ctrl + Alt + F2) and noticed the following message:

[ 307.xxx.xxx] nouveau e [ PBUS] [0000:00:0d.0] MMIO write of 0x00000000 FAULT at 0x00b010

and then, the system goes laggy as hell... Super slow-mo. Seriously.
Back to graphical mode (Ctrl + Alt + F7), moved the mouse and cursor position refreshed after 10 secs. Same thing to keyboard response. Then: System freezes.

apport-collect needs response from browser... So, I'm sorry. This bug makes this impossible.
Can I attach some other information without using browser or graphical mode with dev-ISO?

I really miss Ubuntu in my computer! :(

Allan M. de Azevedo, thank you for your comment. So your hardware and problem may be tracked, could you please file a new report by executing the following in a terminal:
ubuntu-bug xorg

Please ensure you have xdiagnose installed, and that you click the Yes button for attaching additional debugging information.

Thank you for your understanding.

“random pattern tiled across the whole screen” sounds very much like this:
https://bugs.freedesktop.org/show_bug.cgi?id=61321

Nouveau with modesetting is still unusable on 6150SE all the way up to today's vivid. Quantal and earlier are fine.

"nouveau.config=NvMSI=0" does seem to work around the problem. A patch to disable MSI on these chips was linked in the upstream bug report:

https://bugs.freedesktop.org/show_bug.cgi?id=87361
http://lists.freedesktop.org/archives/nouveau/2014-December/019417.html

dmesg still mentions "MMIO write FAULT" multiple times, but that's probably a separate bug; at least it hasn't frozen or scrambled yet.

If I should open a separate report, or provide any additional information, just let me know what you need.

Ryan Tandy, thank you for your comment. So your problem and hardware may be tracked, could you please file a new report with Ubuntu by executing the following in a terminal while booted into the default Ubuntu kernel (not a mainline one) via:
ubuntu-bug linux

I have found that adding nouveau.noaccel=1 to the Kernel command line in /etc/default/grub has solved the lockups. You may want to try.

Can confirm that nouveau.noaccel=1 solved the lockup in my desktop with "GeForce 6150SE nForce 430". But if you need some graphical effects or things like that, forget! You'll have an system 'not bricked', but really ugly.

I'm not using Ubuntu anymore, but last year (with another distro) I give nouveau a try and the same problem that I used to have in fresh Ubuntu install 4 years back showed.

This glitch in nouveau is very annoying. NVIDIA proprietary driver (304xx-lts) don't have a good performance with glx (i.e. if you have compton and some little desktop effects, the delay is huge). Same machine, same NVIDIA driver, but this time with Windows: the desktop don't have such a poor performance.

Nothing is perfect... I have to buy a new computer anyway. ¯\_(ツ)_/¯
