Sorry to hear! I really want to say it again: The manhfacture has to support linux officially. Otherwise there are things not mentioned in the documentation and the maintainers are working nonstop across multiple repositories to make it work.
Thinks of the top on my head not listed in the wikis:
6 or 8 cores with 100% CPU load drains the battery more then it can load (for now?)
no sound via HDMI/display port
doesn’t detect external monitor when booting. Forcing one to replug.
These issues are somewhat mentioned. So I do not want to nitpick. Instead contributed some solutions/hints for things I was able to infer. So please don’t hate me. I’m new.
