How can I require users to also enter their usernames upon login?

Question

Good day,

Does anyone know how to modify the login screen so that users are required to type their username along with their password?

I'm running Ubuntu 12.04 with all default settings

I will be using a mix of ldap users and local users so just want the ability for users to just type their name rather than select from a list — Jan Geep, Jul 02 '12 at 12:18
I have seen this question answered before here, i will have a look for the link. — stephenmyall, Jul 02 '12 at 14:16

You need three settings in /etc/lightdm/lightdm.conf to get exactly what you want:

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

Well I've found one option that seems to work partially

add greeter-show-manual-login = true to /etc/lightdm/lightdm.conf and then reboot.

It still shows local accounts which is not ideal but does allow me to log in with ldap user accounts now.

Tested in Ubuntu 22.04 just now.

sudo nano /usr/share/gdm/greeter.dconf-defaults

Find the line where it says this:

[org/gnome/login-screen]

...and underneath it, uncomment this:

disable-user-list=true

(Required): then, run this:

sudo dpkg-reconfigure gdm3

Now reboot to test it:

reboot

If you are using Kubuntu, the above does NOT work due to a bug in the kde greeter

Create this file: /etc/lightdm/lightdm-kde-greeter.conf and include the following contents.

[greeter]
theme-name=classic
