I use kubuntu 11.10 and 10.* w/o problems .. hmm.
With and w/o compositor (effects, transparency).
Sure, could be some gnome thing and it's compositor,
but last test on CentOS (a while back) and Debian test went ok.
Never had this black in/out 'experience'.
NV 8400GS ? Hmm .. tests on an old MBP w/ an NV 8xxx worked fine as well.

Don't know the state of those drivers .. well.
Just know that Mesa also lacks of pbuffer support,
last time I checked (2 weeks?).
