How to change Ubuntu 12.04 login screen to require full credentials?


A login screen should ask for both user name and password. That is basic common sense security IMHO. With Ubuntu 10.04 I could change the login to require both by executing
Quote:
sudo -u gdm gconftool-2 --set --type boolean /apps/gdm/simple-greeter/disable_user_list true
This of course does not work on 12.04. Can someone point me to the proper method to achieve the same thing on Precise?

TIA,

Ken

Thanks pan64,

I installed and ran gconf-editor and set apps; gdm; simple-greeter; disable_user_list to checked. I then rebooted. No change to the login screen Another Canonical enhancement.

Thanks msieur,

I tried your suggestion but that simply adds the name "Login" to the list. If I click on it I am presented for a prompt for Username. My account name "ken" is still displayed in the list along with Login and Guest Session. Not exactly what I am trying to accomplish.
