[Joseph Salisbury <joseph.salisbury@xxxxxxxxxxxxx>]

I built a test kernel with commit 237ed86c reverted, like in comment
#29.  However,  I also applied the patch for this bug from the latest
Xenial kernel.

The test kernel can be downloaded from:

Title:
  Fails to detect (second) display

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Xenial:
  Fix Released

Bug description:
  With the upgrade to 4.4.0-2, only one of the two displays in the
  machine is detected.  With 4.3.0-7 (and earlier) both are detected.

  In this case, both display connectors are on the MB.
