Looking at the logs, it looks like the last time this happened after an uptime of 8 hours. Can you provoke this, e.g. by running an Unigine demo for some time? Please monitor temperatures using nvidia-settings while doing so.
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:

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.
Another one on battery, after a few minutes of work… On ubuntu GPU crashed very often on battery and power supply, now 90% battery. I will try Unigine demo in a few days.
I did lenovo tests (gpu, memory, etc…) and everything was ok.nvidia-bug-report.log.log (235.6 KB)
Thank you for the advice. I switched around the power cables since others had success and after some initial failure, I have not had freezing problems for months now…yay!!!
