I am closing this bug. I believe the problem was that you didn't uncomment the [org/gnome/login-screen] line.
To disable the user list on the login screen in Ubuntu 18.04 and newer: 1. Edit /etc/gdm3/greeter.dconf-defaults You can use your preferred editor, but I suggest: gedit admin:///etc/gdm3/greeter.dconf-defaults 2. Remove the # from the front of these two lines to uncomment them: [org/gnome/login-screen] disable-user-list=true 3. Save the file 4. Reboot your computer. On Ubuntu 18.10 and newer, you can probably skip rebooting and just run this command: sudo systemctl reload gdm -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1724944 Title: gdm3 doesn't start with disable-user-list=true option enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1724944/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
