When trying to disable the user list for the login screen, none of the methods work after the latest security update applied:
- Setting this manually using dconf and key files does not work (this worked before the latest update)
- Setting this through using gsettings does not work either (the setting is applied when getting the key value by using gsettings get but it doesn't appear to be so, as the users are still listed on the login screen)
- Uncommenting the disable-user-list in custom.conf in the gdm3 directory leads to a crash if/when restarting the computer. GDM never loads, and the screen is stuck on a disk check displaying that /dev/sda is clean
