<pre>I just switched to Optimus mode in the bios.
When I boot Linux, the Intel driver takes over immediately.
In this mode, no external displays are recognized for both VGA and DP ports.
In 'Intel only' mode, Windows is unable to recognize any external displays too,
so i think it is hard wired.
In 'Nvidia only' mode, all external ports are working, except for the bug
described in this ticket.
