Return the Device sections in use

        If no Device sections are referenced in ServerLayout then all of
        the available Device sections are returned.

        This method supports old Xinerama setups and therefore looks for
        references to Device sections in the ServerLayout section(s) and
        checks only the default ServerLayout section provided than one is
        set in the ServerFlags section.Fr-�ServerFlagsrrr%)r'r0�get_default_serverlayoutr:r&r()	r

See if a driver is enabled in the Device sections

        When possible, this method checks only the Device sections in use,
        otherwise it checks any available Device section.

        This method supports old Xinerama setups and therefore looks for
        references to Device sections in the ServerLayout section(s) and
        checks only the default ServerLayout section provided than one is
        set in the ServerFlags section.)
