system.

2.- X crashes and gdm restarts it.

Yeah I see this occasionally, well, the 2nd problem at least.  I have a theory
on what causes it but haven't had a chance to look at it yet.

I've attached something that should workaround the issue if I'm right
about the
cause.  Let me know if it helps!

If it does, I'll look at backporting some of the patches from the -ng branch
of
the ddx which'll be a better fix until -ng is usable.

I've applied the patch and have been using it for 2 days without a single
crash
yet.

I've been using it for 6 days in a row, but it finally crashed the same way,
so it seems to last MUCH longer but still fails.

After 3 months without using nouveau (due to lack of time), i've tried it
again
and this doesn't happen now, so it seems fixed.
