 information or relative motion information. Not all input
 devices are capable of reporting motion data, and not all are
 capable of changing modes from Absolute to Relative.
 

 XSetDeviceMode can generate a BadDevice or BadMode error.

DIAGNOSTICS

 BadDevice
        An invalid device was specified. The specified device
        does not exist or has not been opened by this client via
        XOpenInputDevice. This error may also occur if some
        other client has caused the specified device to become
        the X keyboard or X pointer device via the
        XChangeKeyboardDevice or XChangePointerDevice requests.
 

 BadMatch
        This error may occur if an XSetDeviceMode request is
        made specifying a device that has no valuators and
        reports no axes of motion.
 

 BadMode
        An invalid mode was specified. This error will also be
        returned if the specified device is not capable of
        supporting the XSetDeviceMode request.
