I get this too! Freeze on shutdown/log off
Here are my particulars:
Dell latitude D820 -- Quatro NVS110M (nVidia Corporation Quadro NVS 110M / GeForce Go 7300 rev 161)
Nvida Driver 100.14.11 installed from NVIDIA-Linux-x86-100.14.11-pkg1.run
Fedora 7 ( 2.6.21-1.3228.fc7 )
rpm -qa | grep compiz: compiz-0.3.6-8.fc7
rpm -qa | grep metacity: metacity-2.18.3-1.fc7
With no compiz -- everything seems fine. With compiz - shutdown/logoff problem.
FYI: same problem existed on same hardware under FC 6 (few weeks ago) -- with 100.14.06 (maybe 09 or some beta 100.xxx I tried)......I could roll back to NVIDIA-Linux-x86-1.0-9755-pkg1.run and it seemed to work OK.
For whatever reason, I have NOT been able to roll back to NVIDIA-Linux-x86-1.0-9755-pkg1.run on Fedora 7 (can't find 'nvidia' problem in X log) from NVIDIA-Linux-x86-100.14.09-pkg1.run ..... I have not tried the rollback from 11 yet; nor have I tried rollback to NVIDIA-Linux-x86-1.0-9762-pkg1.run
