def ts_kb_locked(mode):
print 'Screen/keys locked; new mode: %s' % mode

def locked(mode):

DBusGMainLoop(set_as_default=True)
sys_bus = dbus.SystemBus()

#get initial states
mce_proxy_request = sys_bus.get_object('com.nokia.mce', '/com/nokia/mce/request')

ts_kb_locked(mce_request_iface.get_tklock_mode())
locked(mce_request_iface.get_devicelock_mode())

#watch for changes
sys_bus.add_signal_receiver(ts_kb_locked, path='/com/nokia/mce/signal', dbus_interface='com.nokia.mce.signal', signal_name='tklock_mode_ind')
