LightDM Login – How to Prevent Listing All Users at Login?

lightdm

I just upgraded to Ubuntu 11.10 and I was wondering if it's possible to not list all the current users and instead require the user to type in their username? My company's IT policies require that users not be listed on login screens.

In Ubuntu 11.04, I was able to do this with the following commands…

$ sudo -u gdm gconftool-2 --type boolean --set /apps/gdm/simple-greeter/disable_user_list true

Best Answer

You can do this by editing /etc/lightdm/lightdm.conf The default contents are just:

[SeatDefaults]
greeter-session=unity-greeter
user-session=ubuntu

And you can just add:

greeter-hide-users=true

To that. For the full list of options, see /usr/share/doc/lightdm/lightdm.conf (or look at this post about lightdm conf).
