Can T520+Bumblebee run an external monitor via DisplayPort?
Maybe slightly off-topic:
Can anyone confirm that the DisplayPort is hard-wired to the Nvidia GPU? That wasn't the case with the predecessor ThinkPad T510, where I could use the port with the integrated Intel GPU.
I'm on the integrated GPU and xrandr only reports VGA1 and LVDS1. :-(
