[orca-list] Help! I broke my login screen

[Jason Fayre <jfayre cocenter org>]

Hello everyone,
I just tried to do an upgrade from Ubuntu Feisty to the latest 
development version which is called
"gutsy".

After the upgrade, everything seemed to work quite well.  I noticed that 
you can now switch to administrative mode without loosing Orca.  I went 
into login preferences and tried to activate accessible login.  Now, 
when I reboot my system, I do not get the login screen.  UIt looks like 
gdm is dying somewhere.  I am not seeing anything in my logs.  Is there 
a way to undo what I did without being able to log in to gnome?  I can 
log in using the console and I do have a braille display that I can use.
