= Test Cases =
Test Case 1:
- Login under Wayland (session Ubuntu)
- Open a terminal

Result:
- Expected: ^C is displayed in the terminal and the prompt is at the start of
a new line
- Actual: The session is terminated and the login screen is displayed
Test Case 2:
- Login under Wayland (session Ubuntu)
- Open a terminal and type the following command:
$ sudo udevadm trigger
- In the terminal window press CTRL+C
Result
- Expected: ^C is displayed in the terminal and the prompt is at the start of
a new line
- Actual: The session is terminated and the login screen is displayed
= Original Description =
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.
