When I set the LVDS panel to a resolution that is lower than the native resolution it starts to flicker heavily.
My laptop is a HP ProBook 6465b that has a Llano APU. The latter uses a TRAVIS dp bridge chip to provide LVDS connectivity. Setting the scale mode does not seem to have any effect either.
