Dariusz,

Would you like me to update to 14.10 as well and try the utopic patched
kernel? I want to upgrade soon, anyway.

Or do you need my current 14.04 to test trusty stuff?

Hartelijke groet,

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.
