I can't replicate (with GNOME Classic, GNOME, Unity, Unity 2D desktops
installed). When I mistype the username, I am prompted for a password, I
then either type a wrong password, or simply hit return & I get the
'Login - invalid password, please try again|Username'. Even though it is
says 'invalid password' the input box says "Username"; enter the correct
username, then correct password when prompted logs me into my desktop of
choice. Greeter is unity-greeter:

$ cat /etc/lightdm/lightdm.conf

[SeatDefaults]
user-session=gnome-classic
greeter-session=unity-greeter

Xubuntu also uses an additional greeter: lightdm-gtk-greeter:
<https://launchpad.net/ubuntu/+source/lightdm-gtk-greeter>
So perhaps the issue is there?
