[Bug 1710637] Re: Input falls through to gdm3 and terminates the session on Ctrl+C after udevadm trigger is executed under wayland

[Bernd Wurst]

I have this bug on 18.04 with alt+left.

After executing the dumpkeys/loadkeys workaround, then alt+left stops
doing strange things but now, alt+F4 drops me to console 4 which is even
worse.

Bug description:
  = Test Cases =

  Test Case 1:
  - Login under Wayland (session Ubuntu)
  - Open a terminal
  - snap install gimp
  - Wait until installation finishes successfully
  - 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

  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.
