Black screen with nouveau on a GeForce 8600M GT, either LiveCD or fresh install

Don't know why Xorg.log was a "raw data" file, reuploading as a text file.

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

This wiki page has details about how to add a kernel boot parameter for
testing:

https://wiki.ubuntu.com/Kernel/KernelBootParameters

Also, try removing 'splash quiet' from the kernel options and see if that matters. That should bypass plymouth which sometimes can leave the GPU in an inconsistent state.

I still get a black screen when removing quiet splah and adding vesafb.anything=1 as kernel parameters. Xorg.log is attached, 29.900 is when I Ctrl+Alt+F1 to see if that works on the tty (and it doesn't work either). The screen is turned on but black, it's not off.

Note that it kind of works when nVidia proprietary drivers are installed or when I use nomodeset (it actually uses Vesa instead of Nouveau, log attached as well).

Mathieu Marquer - I've forwarded this bug upstream to http://bugs.freedesktop.org/show_bug.cgi?id=35514 - please subscribe yourself to this bug, in case they need further information or wish you to test something. Thanks ahead of time!

Also, if you could please re-test against current natty in case one of the recent kernel updates resolved the issue. (If the bug still occurs, attaching a fresh `dmesg` to the upstream bug report would likely help.

[Typically blank screen on boot bugs are kernel KMS issues rather than X specifically, so adding a linux task.]

As requested on the Nouveau ML, I'm also adding the actual dmesg here in case somebody would encounter the same bug. Basically saying "Composite sync not supported"

Hi Mathieu,

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.

Exact same behavior with kernel 2.6.39-999-generic_2.6.39-999.201104020912

I can confirm this on natty with 2.6.38-8-generic-pae (Dell XPS M1530, GeFore 8600M GT). The proprietary driver works fine. Incidentally this made the upgrade process from maverick to natty very difficult, as for some reason it tried to enable nouveau even though I had the proprietary drivers installed.

Hey slasher-fun,

You filed this bug report against natty, but I see it's still open and
doesn't appear to have much activity recently. So, now that oneiric
is released and stable, this may be a good point for you to upgrade
and re-test if this issue is still present there.

If it's solved in the new release and you think it's worth backporting
the fix, please indicate that. Or if having the fix in the new release
is good enough, feel free to close out the bug (or let us know and we'll
close it.)

If it's not solved, leave the bug report open. I can't promise we'll
get to it (we get way more bugs filed than we can usually get to), but
your testing and feedback can help out if and when we do.

the bug is aslo in the precise daily to yetersday i have written ubuntu low running graphics for the card 8600 gt nvidia . Also the same with the installation nvidia current

Warning ! I have already seen 3 different machines with video cards :

- Nvidia C77 (Geforce 8200)
and
- Nvidia GeForce 315M (GT218)
and
- Another Nvidia which I don't remember

That will not boot Precise at all (and hang on black screen) if nouveau isn't blacklisted with "nouveau.blacklist=1" in grub command line.

I get the same black screen on xubuntu 12.04 beta 2.

Video card: nVidia Corporation GF116 [GeForce GTX 550 Ti]

Would it be possible to attach a dmesg of a more recent kernel version? It looks like not all output connectors are recognised correctly, which explains the black screen.

Probably fixed upstream:

http://cgit.freedesktop.org/nouveau/linux-2.6/commit/?id=a3a285f17867f0018de798b5ee85731ec1268305

This seems to be fixed for me. The only big problem now is plymouth is totally broken, but that's probably related to bug #713088 or some other issue.

Is this still a problem in Precise for anyone?

Mathieu Marquer, thank you for reporting this and helping make Ubuntu better. Natty reached EOL on October 2012.
Please see this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

We were wondering if this is still an issue in a supported release? If so, could you please test for this with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

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 let us know your results. Thank you for your understanding.
