Title:
  X server hangs on start when DisplayPort is connected

Status in xorg package in Ubuntu:
  Invalid

Bug description:
  I just bought a new Acer Predator AG6-710, which supposedly comes with
  a NVIDIA GeForce GTX 980 graphics controller.

  It has four output plugs -- DVI, two mini DisplayPort, and HDMI.

  When I have only one monitor plugged in, on the DVI port using DVI-A,
  i.e., through a DVI-A -> VGA adapter and then a VGA cable, Ubuntu
  boots up just fine.

  However, when I have two monitors plugged in, the first as described
  above and the second through one of the DisplayPorts via a mini
  DisplayPort to DVI-I adapter and a DVI-A cable, the X server hangs on
  boot, and I end up with two blank screens and monitors claiming no
  signal is being sent.

  I've attached the Xorg log file when this happens.

  It happens every single time I boot, i.e., it is reliable.

  WORKAROUND: Use nvidia-352.
