We can not receive dbus signals until it is no one who send these signals :) Already when I implemented the reading switches on the input event devices, I considered that monitoring could be carried out in tde_dbus_hardwarecontrol that would send dbus signals. But that would require first change way to refresh informations in tdehw-lib. -- Slavek
