Interesting. My laptop died a little while ago, and I needed to demo a game I'm working on at a local convention. My wife had a hybrid GPU machine and let me swap in my SSD to run it. The drive had PopOS on it without the NV drivers. It did seem to run wayland fine on the internal display, but the external display was picky. (I wanted to demo on a bigger display) The only way to get the game to run smoothly was to disable the internal display using X11, and run the game using GL instead of Vulkan. >_<
So yeah, kinda mostly worked if I wanted it to be a laptop. I can see how it gets to be a pain if your needs are specific though.
