I'm a very casual Ubuntu user, but I use external monitors with my laptop closed. I fixed the "5 second input lag when main display is off" bug a bunch of times, it seemed to break again every third time I restarted. Eventually I saw a snarky "or you losers could just switch to Wayland" comment, I tried it, and I haven't had a problem since.
I'm learning a lot about the politics of the situation in here! For me, Wayland worked.
