Comment 1 for bug 1371250

Until this bug can be fixed, LightDM should ship a default configuration in /usr/share/lightdm/lightdm.conf.d enabling "allow-user-switching" explicitly, or comment out this code piece at line 980 of file lightdm.c:

        if (!login1_seat_get_can_multi_session (login1_seat))
        {
            g_debug ("Seat %s has property CanMultiSession=no", seat_name);
            seat_set_property (seat, "allow-user-switching", "false");
        }
