Nvidia dgpu/driver and fan issues.

Im not sure these issues should be put together since they seem to have separate source problems, but they do come together.

1. The problems are dgpu not being used
2. The fans not working and the laptop thermal throttiling

DGPU Issue:

Im currently unable to get my Surface Book 2 to use the dgpu.

issuing sudo lsdh -c video gives:

$ sudo lshw -c video

If I issue nvidia-smi, it says it failed because it couldnt communicate with driver.

prime-select query shows nvidia

issued "sudo surface set-runtime-pm on" and when i issue sudo surface dgpu get-runtime-pm, now it shows on. But when i reboot it defaults to "unknown"

I read that this method with the surface command is not working anymore, that could explain the issue with this method.

The Fan Issue:

The fans have never worked properly, and thermal throttling has always been an issue. I have read somewhere here that that was a problem beyond the linux-surface scope. So I kinda just accepted it. But now im trying to see if my system could run some simulations (gazebo for robotics) and the nvidia problem plus the fan issue is making my life difficult.

Any clues as to where the issue could be?
or is this just the normal state of running linux on the SB2?

Thanks
