Hi, (it's related to former thread, but also different) Here the problem, gdm3 restart showed me Could not connect to system bus: failed to connect to socket /var/run/dbus/system_bus_socket: no such file or directory actually there is no /dbus directory under /var/run I checked the dbus and related libs seems installed, or might still lack someone, I don't know how to proceed further, thanks ahead for any advice, best regards,
