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.)
Mint is still on X11, pretty much all other distos switched over to Wayland by now, which works much better with multi-monitor setups.
There’s a subforum in the mint forums about this.
Out of curiosity, what do you recommend instead?
Had issues with screen flickering in grey while on Wayland on a laptop computer
