Hi, I think I am having a similar issue using Ubuntu 19.10 with Kernel 5.3.0-46-generic on 1080 ti with nvidia-driver-435. Randomly over the last couple weeks, my desktop display freezes and I’m unable to use the mouse or keyboard. SSH works fine and I am able to remotely run the NVIDIA reporting tool as well as poweroff the host. It sometimes happens just after I enter my drive encryption password at boot, sometimes during a video-game, but seems to happen more often when using a browser. In all cases my syslog shows the message:
Apr 21 13:00:43 hostpc kernel: [ 3584.430531] NVRM: GPU at PCI:0000:01:00: GPU-bd7638f6-40d1-2ddd-0a8f-5ffbddd256b6

Apr 21 13:00:43 hostpc kernel: [ 3584.430568] NVRM: GPU 0000:01:00.0: GPU has fallen off the bus.
Perhaps a seat-belt might help? :D
Attached are some logs. Two are from days ago and the other 2 are from the crashes that happened when trying to make this post today.
I’ll upgrade the kernel tomorrow, unless there is something else I can run to help diagnose the root cause.
This case seems to have the same problem: Regular Xorg freezes on KDE Manjaro
In this case, upgrading to kernal 5.6 seemed to solve the problem: Display freeze at monitor turn on for a few seconds with NVIDIA 440.59
