Comment 22 for bug 432521

Retested after today's X updates and the problem is still present.

If I logout of the only user session, I get the problem described (cursor only and the KDM screen is present, so I can put a password in, but not see anything other than the mouse pointer). If I activate a second user session (from the option from a locked screen) I can start the new user session, switch back and forth, and log out of the second one with no problems.
