Bug#683338: I have had the same issue with gdm greeter quite a few times.

[shirish शिरीष]

Hi all,
I have been having the same issue as Salvatore Bonaccorso even though
mine is gdm:3.6.1-2 version and not gdm3.4.1-8 .

By same issue I mean

"But the problem does not seem only present when disabling the user
listing. Even with disable_user_list=false, after cancelling a login,
the greeter gets confused and it's not possible anymore to scroll the
user list shown." - Salvatore Bonaccorso

I have to be very careful when logging in otherwise the only option is
to reboot the system.
