        Kernel driver in use: nouveau
        Kernel modules: nouveau

Xorg log says:
[    14.374] (EE) NOUVEAU(0): Error creating GPU channel: -19
[    14.374] (EE) NOUVEAU(0): Error initialising acceleration.  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.

I forgot to mention that I cannot reproduce the segfault.

> 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
