Bug#656092: usability: should ask for password right away, if there is only one user

[Michael Below]

Package: gdm3
Version: 3.0.4-4
Severity: minor

Dear Maintainer,

on my system there is exactly one user allowed to login into
X/gdm. This is the default when a new system is set up. The login
procedure for this common case should be made easier: 

I have to select the single valid option (my username) and then
enter the passwort. The option "others" that is offered as well
doesn't have any use in the default config, since I can't login
into X as a system user. It might be possible to login remotely
into another system using this (not tested), but that's not the
common use case.

If there is only one valid user account for GDM login, GDM should
ask for the password right away. Having to click/press enter in
advance is bad usability. If necessary, things like remote
sessions could be offered in the sessions menu that is available
in the password dialog. 

Thanks for your work

Michael Below
