I use Fedora 8 on my laptop, they contain feature for multiple logins. When i loging to my laptop more then once i can't switch backward to the previous user because system is stucked.

I make simple sequince test for single user login/logout everything work fine. I can see login dialog and can login multiple times with out problems.

steps to reproduce stacking, on system with two users:
1. login with first user
2. use New Session from Gnome menu or Fast user switching.
3. login with another user
4. press New Session again or use Fast user switching to previous guy.
   or press ctrl+alt+f7.
5. system lose video output.

really i can hear music and feel background work, if i blend press ctrl-alt-del system well rebooted, but i can't able to see console or X11 by any keysequince.

My system have default configuration without framebuffer enabled.

here is my previous bug report with same system installed, you can see logs or configs. http://bugs.freedesktop.org/show_bug.cgi?id=14507
