I use zorin 16 pro for work on my Dell XPS 9710, and for whatever reason as I'm working screen will just go black as though it is going into a sleep state.
Went into power settings and adjust all of the suspend options or blank screen but for whatever reason it still goes black from time to time which typically requires a restart to be able to view my desktop/gui.
I suspect you might be correct. When I'm using Zorin, fans never came on, but in Windows, fans do come on to cool down the laptop. Not sure why that would be the case. I assume some package related to cooling may be missing. Also an fyi I did update to the latest NVIDIA driver 495.xx. That did not fix the issue.
So per article made the change from Balanced to Performance. Fans still haven't kicked in so not sure how well this has worked. I will test further, later today and report back. At work so can't test at the moment.
so seems like fans run only for a short time. Basically if I suspend the laptop then bring it back fans don't run and I'm then back to dealing with screens blacking out.
Hey, if fans work with windows but not with zorin then I suggest installing greenwithenvy. It's software that allows you to check your GPU temps and control your fans. I hope this helps.
