Title:
Ubuntu Desktop ISO fails to boot with nouveau on a displayport
Status in Release Notes for Ubuntu:
New
Status in linux package in Ubuntu:
Confirmed
Bug description:
On the latest daily artful image (/current as of 2017-01-14), the
following occurs on a system with nVidia graphics (on my system, a
GTX970) when connected to a 4k display over a displayport:

Steps to reproduce:
- Download latest daily image, check checksums, burn to USB
- Boot from USB.
- Choose "Install Ubuntu" or "try ubuntu" at the menu.
This happens on the livecd, but also upon ugrading the system from a
previous daily with a different kernel: my "old" daily booted and
installed fine with kernel 4.12.0-12, then failed with same error once
dist-upgraded.
On the faulty system I could test with, it seems to *only* happen over
displayport/on a 4k screen (I don't own a non-4k displayport screen to
test the 4k out).
