Bug Description
On the latest daily artful image (/current as of 2017-10-14), the following occurs on a system with nVidia graphics (on my system, a GTX970) when connected to a 4k display over a displayport: https:/
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).
