From: Ville Syrjälä <[email protected]> The hardware allows a lot more cloning options than what the driver currently allows. There are certain easy cloning cases like VGA+HDMI and HDMI+HDMI which can be enabled very easily, so let's just do it.
LVDS+VGA would be another combination that should be generally available, but unfortunately the way the KMS API deals with the panel's fixed mode makes things much more complicated. As it stands, I suspect simply enabling LVDS+VGA cloning would too easily result in a non-working VGA display. So leave it out for now.
