Jonathan Kamens, I'm not sure what you are going on about, but you found
an offense where none was given. Despite this, since you aren't
interested in pursuing this further, there is nothing further to do with
this report.
However, if you would like to see this pursued further, please do as
previously requested and we may take it from there.

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.
