Just giggled as my last meme mentioned trouble with displays and appropriately, a large chunk of the replies were “well MY displays work just fine!” (And charmingly, many were thoughts of things to check, other distros etc. It’s a very kind community, though that may also be the fediverse.)
You might just have learned more about how stuff works by now. Arch is very much “you need to make every choice manually, but then you’ve seen what choices exist”
