I removed the nvidia proprietary drivers and tested again with the
Nouveau drivers. This lead to almost the same result: black screen,
although with responsive mouse cursor, can't access console, can't login
to previously logged users, however X could be restarted
(CtrlAltBackspace was previously enabled).

** Description changed:
Binary package hint: gdm
This system is running Lucid beta 1 with latest updates (so, up to RC).
It has one main admin user and 3 other users, all using encrypted home
directories. I created two extra test users, one with encrypted home and
one without. I was able to reproduce this problem with any combination
of users.
Steps to reproduce:
- Login as one user (A)
- Switch to user (B)
- Logout
Result: GDM / X crash - can't access console or zap X (X session kill
shortcut Ctrl Alt Backspace is enabled).
This results in data loss for user (A). In my use case, at home, I often
remain logged in when I am nearby the system, and my 2 daughter and wife
login.
Switching back and forth from any user works, however as soon as one
user logs out completely, it will crash the system as described above,
requiring a restart (hard power-off, restart).

When multiple users login, GDM doesn't come back after any of them logs out
leading to DATA LOSS for the others
