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.)
I find the best way to get help is to find a good source of documentation, rather than asking questions directly. ArchWiki is great, UbuntuWiki is not bad. There are lots of blogs out there with people writing guides for how to solve issues that they’ve had, and they’re usually really good (but this relies on search engines finding these results).
