I’m biased, but Mint now has an official guide too:
https://guides.frame.work/Guide/Mint+20.3+Installation+on+the+Framework+Laptop/110?lang=en
written by Nirav himself.
I have not had a single issue on my Framework with Mint. Not a one. It’s so stable it’s boring actually. ![]()
Just watch what kernel you use and you’ll be fine.
