After upgrading to 18.04 the login prompt on my laptop acts really strange:
It wait's for the input of the user name and after pressing ENTER it behaves as if the ENTER key is stuck and gives no chance to enter the password.
Here is a picture:
The exact step that happen are as following:
1. It shows the normal login prompt
Ubuntu 18.04.1 LTS computername tty1
computername login: _
2. It wait's for the input of the username and until you entered the username it behaves normally.
3. As soon as you press ENTER to confirm the username it immediately goes on to
Password:
Password:
Login incorrect.
Without waiting for any user input.
So there is no chance to login to this PC anymore?!
