Title:
  Resolution too low on external monitor through Intel graphics,
  reversion in 4.x kernel

Status in linux package in Ubuntu:
  Expired

Bug description:
  I have the incorrect resolution on my external monitor since upgrading
  to 15.10 with the 4.x kernel.

  Playing with xmode lines manually via xrandr has failed -- when I
  create a correct 1920x1080 modeline and force it, it is unable to
  display.

  Booting with the 3.19.0-26 kernel fixes the issue.

  The Machine in question is a Dell XPS 12. Video card: Intel 3rd Gen
  graphics controller.
