So I am seem to have the proper driver. I also tested that driver and your kernel at home on a Dell E6430 with an Optimus chipset, with Bumblebee set to intel mode. I got no external monitors recognised (instead of 1, but had 2 connected) and my external usb from the replicator ports did not work. Seems like some things are not right on it. By the way, the source I used to compile my kernel are from the git source of David Airlie: commit 91c403ffa85f17b8e349a510f3c32226a025da89 Author: Dave Airlie <airl...@redhat.com> Date: Mon May 12 15:22:27 2014 +1000 git://people.freedesktop.org/~airlied/linux Greetings, Vincent On Mon, Oct 20, 2014 at 5:28 PM, Dariusz Gadomski < 1104...@bugs.launchpad.net> wrote: > VIncent, according to [1] this hardware is displayport 1.2 compatible. > "Plus, the Display Port 1.2 adds the ability to daisy chain displays (4 > displays via 1 connector)." > > However, I have not been able to determine whether this works in such a > way that it takes MST output from your laptop's displayport and > distributes it via vga and dvi ports. > > Do you remember what feature have you been cherry picking to your > patched kernel?
