I have the following system:

$ lsb_release -a
Distributor ID: Ubuntu
Description:    Ubuntu 17.10
Release:        17.10
Codename:       artful

$ gdm3 --version
GDM 3.26.1

I would like to disable the user list in GDM and enter my user name and password to log-in. I have already searched a lot but did not find any valuable solution.

How can I achieve this?


This feature is currently bugged, see: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1724944 and mark yourself affected

You need to install the dconf-editor tool if you not have already:

sudo apt install dconf-editor

Then when you opened it navigate to:


and set the 'disable-user-list' button to 'on':

enter image description here

Since the above is still bugged, the only solution is right now via terminal edit the following lines in /etc/gdm3/greeter.dconf-defaults:

# disable-user-list=true



Be sure to edit both lines otherwise you might crash your login completely.


One option:

Edit /usr/share/gdm/greeter.dconf-defaults and remove "#" to uncomment the line:


Another option:

Use gconftool-2 or gconf-editor. Change this value to true:

    See comment made at the other post. You also need to uncomment [org/gnome/login-screen] if you do it your way. Only doing your uncomment crashes the login. – Rinzwind May 30 '18 at 8:54
