Hi Dariusz, Good news! I tried your kernel on a different laptop with a fresh 14.10 install and everything is working great. The networking is working and both displays are recognized separately!
I have attached the output of the i915_dp_mst_info files if its still relevant, but everything appears to be working great! ** Attachment added: "i915_dp_mst_info.out" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1104230/+attachment/4249111/+files/i915_dp_mst_info.out -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1104230 Title: DisplayPort 1.2 MST support is missing in the Intel driver Status in X.org xf86-video-intel: Unknown Status in “xserver-xorg-video-intel” package in Ubuntu: Confirmed Bug description: I have two recent DisplayPort monitors, both supporting the 1.2 version of the standard and one containing an MST hub (DELL 2913WM). I have an Intel Haswell based NUC connected over mini-displayport to the display containing the hub, then the second display is plugged in that one over DisplayPort. DisplayPort 1.2 is enabled on the display containing the hub and the second display lights up fine but just works as a clone of the first display, without ever showing up in xrandr, dmesg or any other useful logs I could find. My understanding of MST is that the second display should show up as DP2 on my laptop so I can configure it as I would any other display. UPDATE: Updated the bug report after it was pointed out that the original test hardware, a Lenovo x230 isn't DP 1.2 capable. The same test on hardware also fails, due to missing support for MST in the driver.
