--- Comment #1 from Ilia Mirkin (imirkin at alum.mit.edu) ---
There weren't a ton of changes to nouveau between 4.19 and 4.20. Can you do a
bisect?

There were some changes to add support for HDMI 2.0, but only on GM20x GPUs
(you have a GK10x GPU, which is earlier). And a handful of fixes to MST-related
object lifetime management. It's likely that you have a MST dock, but those
changes don't seem like they would cause anything that drastic.

Please include dmesg and xorg logs.
