Description:
GDM is the GNOME Display Manager which handles graphical login for GNOME based systems. The disable-user-list option controls is a list of users is displayed on the login screen.
Rationale:
Displaying the user list eliminates half of the Userid/Password equation that an unauthorized person would need to log on.
Fix:
Edit or create the file /etc/gdm3/greeter.dconf-defaults and edit or add the following:
[org/gnome/login-screen]
disable-user-list=true
Run the following command to re-load GDM on the next login or reboot:
# dpkg-reconfigure gdm3
Parameter:
[yes/no]
Technical Mechanism:
Edit or create the file /etc/gdm3/greeter.dconf-defaults and edit or add the following:
[org/gnome/login-screen]
disable-user-list=true
Run the following command to re-load GDM on the next login or reboot:
# dpkg-reconfigure gdm3
