<pre>It's more common to attach logs... otherwise the bug reports become very
unwieldy to read.
[ 1743.737807] nouveau ![ PFIFO][0000:01:00.0] unhandled status 0x00800000
[ 8543.865800] nouveau E[ DRM] GPU lockup - switching to software fbcon
[ 8558.870800] nouveau E[ X[808]] failed to idle channel 0xcccc0001 [X[808]]
The unhandled PFIFO bit comes _way_ earlier than the gpu lockup... so probably
unrelated.
The fact that X segfaults when the GPU locks up is a little unfortunate, but
right now this situation is completely unhandled by the userspace stack in any
case. Ideally the GPU wouldn't lock up :)
A quick and easy thing to try is blob pgraph firmware instead of nouveau's.
Take a look at <a href="http://nouveau.freedesktop.org/wiki/VideoAcceleration/#firmware">http://nouveau.freedesktop.org/wiki/VideoAcceleration/#firmware</a>
for a quick and easy way to get it (yes, I know it says it's for hw video
decoding accel, but the script extracts all fw). Follow those instructions and
add
nouveau.config=NvGrUseFw=1
to the kernel command line (or when loading the nouveau module); make sure that
the firmware files are available when the nouveau module loads (so if it loads
from your initrd, they need to be in your initrd).</pre>
