I am running an up-to-date installation of Arch Linux and GNOME 3.28. For security reasons I don't allow root login in the consoles. I have done this by configuring
However, it worries me that in the GUI I can still login into the root account from the GNOME GDM login screen.
Is there any way to prevent this so that only standard user accounts and administrator accounts can login from the graphical login, but not the root account?
