yum remove kmod-nvidia (also removes xorg-x11-drv-nvidia and
kmod-nvidia-2.6.23.9-85.fc8) makes the problem go away.

Comment 2 Ricky Ng-Adam 2008-01-02 02:10:21 UTC

as the accelerated nvidia driver is from Livna, I've also opened a bug there:

Comment 3 Matthias Clasen 2008-02-05 17:09:31 UTC

There is nothing the fast-user-switch-applet can do to fix this problem. 

It needs deep changes to the underlying X/kernel architecture, which are
currently underway.
