Since today I can’t login to gnome.
In GDM I see my user and click on it.
The password field appears but disabled (no input possible) and just under a label sayin’: «Last login {date} on tty2»
After 3-4 seconds the login returns to his initial state, displaying user chooser.

I remember that yesterday I accidentally changed from current gnome’s tty to another…

Another strange thing is that when I switch to another tty (i.ex. tty3) the username is asked, i type it and enters directly without asking for password.

What’s going on?
