How To Require a Username at Login

I've always kind of liked the extra security that came with having to enter your username as well as your password at login. It also, I find, looks better.

Here's how to do it.

1. Open the following file in a text editor...

/etc/lightdm/lightdm.conf

2. Simply Add the following lines...  

greeter-show-manual-login = true 
greeter-hide-users = true 
allow-guest = false

3. Save, restart and see the effects!
