Fingerprint Reader with Gnome

Got some progress. I got the Gnome Settings User panel to recognize my fingerprint setup. I had to enable the right driver (which is weird that it worked at all without it).
For the Thinkpad Carbon X1 Gen 9 it is:

    fprintd = {
      enable = true;
      package = pkgs.fprintd-tod;
      tod = {
        enable = true;
        driver = pkgs.libfprint-3-tod1-vfs0090;
      };
    };

For GDM not allowing a password at all, found this bug with other reports. So it’s not just me.
