Description of problem:
X using Xinerama (AGP NVidia GeForce2 MX 200 as primary using nv driver, PCI
Voodoo3 2000 using tdfx driver) hangs on logout from gnome.  After logout, X
restarts to gray screen with X mouse cursor; no login screen.  The mouse pointer
moves when the mouse is moved, but the keyboard is locked so I can't get to a
terminal, can't do emergency shutdown (Ctrl-Alt-Del), can't restart X
(Ctrl-Alt-BackSp), and I have to use the reset button to get linux back up. 
Keyboard is set up to use US standard 105 key, mouse is USB logitech, X version
is whatever came prebuilt with RedHat 8.  I assume that this is a gdm problem,
but I don't know how to test it.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Install RedHat 8.0 on computer with graphics cards mentioned above.  Note
that automatic X configuration will fail and you will have to tinker with the
XF86Config file yourself.
2. telinit 3 to get to non-X mode.
3. Tinker with the XF86Config file, putting the AGP card as the left screen and
the PCI as right.
4. telinit 5 to restart X mode.  gdm starts fine, login screen is on one screen
instead of on the line between the two monitors (very nice).  Login to gnome.
5. Play around in gnome for a bit setting configuration to how you like it.
6. Logout.  X will hang as described above.
	

Actual Results:  X hangs, have to reboot the computer to get linux back.  It's
possible that you can telnet (or ssh) into the computer and kill X, but I don't
have another computer with which to test that.

Expected Results:  The login screen should come back up, and the keyboard should
still be enabled.

Attach X config, and log file using link below please.

Closing bug due to inactivity and lack of information.

Happens for me also in RH9 and FC1 with all relevant updates.

Additionally, if Gnome is exited via CTRL+ALT+BKSPC everything is
fine; the X server will reinitialise itself correctly with the login
screen.  I am happy to perform any testing required.
