Falling back to NoAccel If I do not set "nouveau.noaccel=1" on kernel line I just get a black screen and a segfault. I am using Gentoo and the external drm driver. Nouveau Feature Matrix says that 3d should work for my GPU. What can I do to help? Do you need additional informations? Thank you
Please, provide complete kernel and X logs as instructed in http://nouveau.freedesktop.org/wiki/Bugs for the black screen and segfault case. Note, that while your aim may be 3D acceleration, your problem is not a Mesa or 3D bug. When working on the black screen issue, please remove the 3D driver (nouveau_dri.so, which belongs to Mesa) to reduce the possible points of failure. Noaccel disables all 2D and 3D acceleration, and is merely a workaround to get to the desktop.
I am using built-in DRM, xf86-video-nouveau, staging nouveau and Kernel 3.0 on Gentoo. Thank you

I forgot to mention that I cannot reproduce the segfault.
does it work if you boot with nouveau.nofbaccel=1?
(In reply to comment #6) > does it work if you boot with nouveau.nofbaccel=1? No. I get a black screen with a cursor which I can move. I attach the Xorg.log and the kernel-log.

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
