How to change Unity's default login screen to allow users to type in their logins and passwords?

Question

Installed Pangolin 12.04 X64 I would like to change the login screen. The default screen let's you choose the user by scrolling which can be a nightmare if you have a lot of users. I just want the user to type login and password.

Answer 1

Using LightDM

Edit the the /etc/lightdm/lightdm.conf using this command

gksu gedit /etc/lightdm/lightdm.conf

And add these two lines to the [SeatDefaults] section

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