Description of problem: Multiple X sessions frequently results in original session being logged out. After creating multiple X sessions, switching back and forth will eventually result in a view of the console followed by the spawning of a new GDM login screen. The process looks exactly like that happens when you log out the last user from X and the system restarts gdm. It does not appear to be a crash or anything like that, at no point (when the switch fails) do I see the expected user X session. The session you were expecting to see is destroyed, but the others seem to remain running. How reproducible: Intermittent, it happens very frequently on my system that I'm testing F7T3 on, but I can't seem to make it happen on demand. For instance last night I tried logging in three concurrent users and switching back and forth, it worked fine. I left the second one logged in over night, in the morning attempted to switch to the second users desktop (worked) and returned to the first (didn't work) on the first try. Steps to Reproduce: 1. Login with first user account. 2. Spawn a second login either with Applications -> System Tools -> New Login *OR* the user switcher Gnome applet and login with a different user account. 3. Switch back to first user account, either with Control + Alt + F7 or the user switcher. As mentioned above this is not necessarily guaranteed to happen and it may take some time for the problem to surface, I haven't yet been able to isolate exactly what has to happen for it to take place. Additional info: Using Nvidia's driver built from srpm on Livna against the most recent Fedora 7 kernel. Not sure if they will be helpful but attaching three X logs from my system as well as this snippit from /var/log/messages: Apr 26 08:13:35 kramer gdm[3316]: gdm_slave_xioerror_handler: Fatal X error - Restarting :0 Apr 26 08:13:35 kramer Synergy 1.3.1: FATAL: CXWindowsScreen.cpp,1590: X display has unexpectedly disconnected Apr 26 08:13:35 kramer gconfd (dev-3444): Received signal 15, shutting down cleanly Apr 26 08:13:35 kramer gconfd (dev-3444): Exiting Apr 26 08:13:41 kramer gdmgreeter[22863]: minimum height is 768 Apr 26 08:13:41 kramer gdmgreeter[22863]: minimum height is 768

I believe this issue is related to the binary nvidia driver and that this means it is beyond the scope of official Fedora support. Will be working to track down the fit through other forums.
