This would solve your problem if we made the X server set the first output known to be connected as RandR primary. In short, I see two different "bugs" here: * radeon reports connector_status_connected when the lid is closed. * the X server doesn't select a primary output among the definitely connected ones. > Cheers, > Jerome > _______________________________________________ > dri-devel mailing list > dri-devel@xxxxxxxxxxxxxxxxxxxxx > http://lists.freedesktop.org/mailman/listinfo/dri-devel
