default user with browser, typing user-password to login

[Sven Jaborek <sven-tek gmx de>]

Hi list,

im using the face browser with a theme like this
http://art.gnome.org/themes/gdm_greeter/533/ .

My question is, is it possible to fill in the username field
automatically? So i only have to enter my userpassword at startup? I
would really like this behavior and think its enough security for my
private system.

I could imagine it in some ways, either with a static defined username,
or with the last username logged in, or even with the username who has
logged in most of the time during the last X days.

regards, Sven
