Getting mini-displayport working on T530
I have hooked up an external monitor with and apple mini-display to dvi adapter and a dual-link dvi cable, but struggle to make this setup work.
At first I had forced integrated graphics in the BIOS. The mdp (mini-displayport) showed no signs of life. I figured that could maybe be expected.
When I forced discrete graphics, the laptop would not boot at all (I didn't get to the step where I should enter my crypto-password).
Now I have enabled Optimus, but disabled OS detection, and the situation is the same as with integrated graphics.
Anyone got an idea how I can make this work? What are the correct BIOS settings, and which driver should I use?
