+Pour désactiver le login avec smartcard, je me suis inspiré de la
+documentation [GNOME - Disallow login using a fingerprint] propose de
+créer un profil `user` pour `dconf`, hélas, ça ne fonctionne pas !  
+En revanche, avec un profil `gdm` comme dans [GNOME - Add a greeter logo to
+the login screen], c'est bon, on observe le comportement attendu, lorsque
+le dongle PKI est présent dans le port USB, c'est bien un login/password
+qui est demandé par GDM.  
+Documentation pas à jour ?
