It would be great if anyone can explain the complete set of steps of how to install the packages needed to test this in 14.04.
I have found no repo with debs to test and the ones I found are not compatible with current xorg and such.
I thought I was fairly experienced with this, but I have not been able to figure it out.
I compiled and installed a 3.14 kernel which should have some patches, and tried the intel installer with it to no avail.
Again, I am happy to test, but I could really help some instructions and help from the people here that seem to be able to install it.
Happy to provide feedback

Title:
  DisplayPort 1.2 MST support is missing in the Intel driver

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.
