Description of problem: Under gnome (kde not tried), when a user is logged in and tries to switch to another user (whether from menu "system-log out <user>", from the applet, or when the screen is locked by screensaver), the display starts to return to the login screen but only displays a partial view of it.  The keyboard doesn't respond, the mouse cursor is visible and cursor tracks but no clicks work.  So it's impossible to do ctrl-alt-f2 or ctrl-alt-backspace, etc.  The only alternative is to turn the machine off with the power button or login remotely (e.g., via ssh) and give the reboot command.


Version-Release number of selected component (if applicable):
  gdm-2.24.1-4.fc10.x86_64
Not sure if this is really the culprit.  It's an fc10 system with all updates installed.


How reproducible: 1. Login as a user, under the default setup with gnome.
   2. Click on switch user in any menu it appears in.

Steps to Reproduce:
1.Login
2. Click on switch user
3.
  
Actual results:  display and keyboard lock, mouse cursor tracks but clicks have no effect.  Remote login via ssh still works.  To restore any local access, the machine must be rebooted.


Expected results: switch user works, and works repeatedly
