Bug Description

In Ubuntu I regularly use the user switching feature which basically spawns multiple X Servers.
This has never been a problem until Lucid.

Now when I switch from one user to another, sometimes the X server being switched to freezes and takes up 100% CPU on one CPU core. Then I have to ssh into the machine and kill -9 the frozen X server.

Suspending and Resumes improves the chance greatly (almost 100%) to reproduce the bug:

1) log in one user
2) use the gnome panel applet (indicator-applet-session) to log in another user.
3) suspend/resume
4) switch back to the first user

Although I filed a bug in nvidia-graphics-drivers, I doubt that they are the only source of the problem, since the same driver worked fine with karmic.
