  Hmm, I was only thinking of Wayland where we have the Wayland protocol. So maybe sebas suggestion of dbus service. It's still possible to race of course but that's something we should be able to handle. Activating the sensor takes it time so dbus should be faster. Then kscreen can ignore all rotations.
