Ubuntu hangs after grub when an external monitor connected to ASUS
N73SV via HDMI or VGA.

With the HDMI/VGA disconnected Ubuntu starts fine. After Ubuntu completely
loaded the external display can be
connected without problems. At this time it is detected properly and works
perfect. The desktop is shared fine to it.
i.e each time I turn it on I have to disconnect external display, wait until
Ubuntu login screen displayed, then connect
the external display again.
