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.)
arch wiki is good, been using that since i migrated to cachyos in september (had been running win 11 pro for years prior to that). only major issue i had was display related lol, i use a tv that needs a custom EDID to expose 120hz mode and it was an absolute nightmare trying to generate it with linux. ended up using a linux tool to dump my existing EDID then popping it into CRU via wine to generate the new one. Works pretty damn well have to say.
