Summary: depends from D9521 listens to switch events and updates the tablet mode status which is exposed to dbus in the org.kde.KWin.TabletModeManager interface Test Plan: as hardware support is limited, testing of clients so far is done by the setter in the dbus property, which should be removed from the final version. It has been tested to successfully work on a Thinkpad.
