(workaround is using default nv driver)

Actually no oops, seems X may be hanging rather.
Comment 4 Robert Laverick 2008-05-14 00:31:09 UTC 
I can confirm this problem.  Nouveau will only work once per reboot.  If you
reboot with the nouveau driver enabled in xorg.conf then the boot progress x
server instance counts as the working one, and then that is killed ready for the
kde login manager then x will crash out.  the only way to get it to work is to
use the nv driver, and to switch to nouveau after boot up, where it seems to
work perfectly until the x server is restarted on log out.

Interestingly switching from nouveau to nv after it has failed to restart will
not resurrect the x server and I have to reboot to get it working again.

I've tried compiling the drm and an nouveau modules and the nouveau driver from
their separate git trees without any change to this problem.
Comment 5 Bug Zapper 2008-05-14 06:49:27 UTC 
Changing version to '9' as part of upcoming Fedora 9 GA.

Can the version also be changed to "10"? This bug is still present on my Fedora 10 system. I'll attach my Xorg.0.log as well.

X.Org X Server 1.5.3
kernel: 2.6.27.15-170.2.24.fc10.i686

Done.
Comment 10 Ben Skeggs 2009-04-09 06:22:38 UTC 
Are you able to try F11 by any chance?  This should hopefully work OK there.
Comment 11 Nicola Soranzo 2009-07-04 00:06:21 UTC 
I can confirm it works in Fedora 11, closing.
