Ok, I'm reopening this because the default could be better. I have filed a Debian bug for input.

[Bug 1724944] Re: gdm3 doesn't start with disable-user-list=true option enabled
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

[Bug 1724944] Re: gdm3 doesn't start with disable-user-list=true option enabled
And the 2nd point is also an "user" problem. When we use the dconf-editor GUI we are changing the dconf keys for the user that executes the command, usually your personal user. So changing it from there has no effect because the user that launches the greeter is different; 'gdm'. So the solution is change the dconf key for the user 'gdm'. I don't know how to do it from the dconf-editor GUI so I give the old fashion way: Using root: - Create a file named '/etc/dconf/profile/gdm' with this contents: user-db:user system-db:gdm - Create a file named '/etc/dconf/db/gdm.d/50-disable-user-list' with this content: [org/gnome/login-screen] disable-user-list=true - Execute the command 'sudo dconf update' And that's all. It changes the dconf setting for user 'gdm' and after reboot the greeter works as expected: asking for the user instead of showing the users list. And this solution works in both Ubuntu 17.10 and Ubuntu 18.04 Beta 2!!! -- 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

BTW: as Joris Le Blansch wrote, using dconf-editor GUI to set /org/gnome /login-screen/disable-user-list to ON has no effect and after reboot userlist is shown as before. So, at this point: 1.

I managed to get some journalctl entries related with the gdm starting error: abr 09 20:54:01 testuser-VirtualBox generate-config[699]: warning: Failed to read keyfile '/usr/share/gdm/dconf/90-debian-settings': Key file does not start with a group abr 09 20:54:01 testuser-VirtualBox systemd[1]: gdm.service: Control process exited, code=exited status=1 abr 09 20:54:01 testuser-VirtualBox systemd[1]: gdm.service: Failed with result 'exit-code'. abr 09 20:54:01 testuser-VirtualBox systemd[1]: Failed to start GNOME Display Manager. The file '/usr/share/gdm/dconf/90-debian-settings' is an softlink to the file '/etc/gdm3/greeter.dconf-defaults' and suddenly I realized that this is not a bug: it's my fault from the beginning!!! :( There is another line that must be also uncommented in order to get it to run, the previous 'group one': #[org/gnome/login-screen] and # disable-user-list=true After uncommented both lines the greeter works as expected in Ubuntu 18.04 beta 2: asking for the user instead of showing a list. But in Ubuntu 17.10 it's still showing the users list. So I think it's fixed in Ubuntu 18.04 Beta 2.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status.
