Comment 32 for bug 996791

I'm also getting a black screen, then a black screen with a mouse cursor, then the login screen after a logout.

I forgot to mention that my user account isn't shown on the login screen, I have to type the user name manually.
This happens both after reboot and after logout.
Just noting that for completeness, this effect is a negligible annoyance for me.

System: Xubuntu Precise 64-bit with nvidia-current-update.

More info on request, or as it becomes available.
Though I'm off trying to install KDE now... and if that doesn't help, some other distro.
