If the system started with VGA connected, the desktop like GDM cannot get
DP's CRTC when DP device is plugged in, because there is only one crtc
sharing use of VGA and DP. So change VGA to disconnected when DP is
connected.
NAK. I think we discussed this when the previous patch was submitted.
VGA and DP are independent. It should be user's choice whether to use
VGA or DP if both are connected.
Acutally, although we are developing drm drivers, our requirements
and testing department's goal is to displaying desktop systems(like GDM), so we
have to
solve different OS or display managers problems, and let the driver handle more
situations.
