["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Roland Dreier, thank you for reporting this and helping make Ubuntu
better. As per http://support.lenovo.com/us/en/products/laptops-and-
netbooks/thinkpad-t-series-laptops/thinkpad-t440p an update to your
computer's buggy and outdated BIOS is available (2.36). If you update to
this following https://help.ubuntu.com/community/BIOSUpdate does it
change anything?

If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful. As well, you don't
have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible, and the
information above is provided, then please mark this report Status New.
Otherwise, please mark this as Invalid.

Thank you for your understanding.

Title:
  Displayport monitor attached to docking station doesn't work with
  Haswell/Intel gfx thinkpad t440p

Status in xserver-xorg-video-intel package in Ubuntu:
  Incomplete

Bug description:
  I have a Lenovo T440p laptop with a displayport monitor attached to
  the docking station.  If I turn on the laptop in the docking station,
  the monitor works under the BIOS but once I get into Linux the monitor
  doesn't light up.  I see the following in kernel log (full logs with
  drm debugging turned on via xdiagnose attached):

      [  116.951792] [drm:intel_dp_start_link_train] *ERROR* failed to
  enable link training

      [  116.954504] [drm:intel_dp_complete_link_train] *ERROR* failed
  to start channel equalization
