Public bug reported:
Multiple times a day I find myself without a session after hitting
Ctrl+C in a terminal, it seems the input falls through the Ubuntu/GNOME
session and to gdm, which itself decides to terminate.
Even worse, when this happens, you can briefly see your login password
in plaintext in the virtual terminal. You can see the password however
long you want if you stop the gdm service when this happens.
I don't have a good way to reproduce, but it seems locking the session
with a keyboard shortcut, subsequently unlocking it, maybe suspending,
at some point brings this behaviour into the picture, until the session
dies with a Ctrl+C.
