Not OP, but I use sunshine and moonlight for streaming my pc to various devices. Wayland forces me to use kms and I can’t turn the monitors off while I’m doing it. Someone was working on a pipewire backend, so hopefully that goes somewhere.
GreenWithEnvy is also a nuisance on Wayland while Nvidia Settings Panel doesn’t even work. I have a custom script just to control my fans on Wayland, but I’m eventually switching from Nvidia anyways, so it won’t matter for much longer.
