** Description changed:
Binary package hint: xorg
I log in as one user, then do a switch user to a different user. Then I try
to switch back and the Xorg crashes. I would like to find more details about
the crash but don't know how at this point.
The only fix I can get so GDM is up again is to do a remote login and
shutdown -r now.
The shell output of the ubuntu-bug -p xorg is:
ubuntu-bug -p xorg
Error: Cannot open display ":0 -"
Exiting
When I log into the shell while this is happening, I see in the process list
with ps -aux that gdm is having trouble getting screen :0

I notice it says my DFP is a CRT, not sure why, but just in case it matters.
