Ubuntu Gnome Shell Remix: remove user from login manager

I hate that login managers tend to display more info than they should, specially nowadays, because it is considered more friendlier.

On the Ubuntu GNOME Shell Remix, in order to get rid of your username being automagically printed onto the login manager you'll have to edit the file:

/etc/lightdm/lightdm.conf

You have to simply append this two line to the end of the file:

greeter-hide-users=true
allow-guest=false 

And then reboot, tried doing a simple login out, but it got stuck.
