I think you may be mistaking what I meant? Wayland is a display server protocol, like Xorg, which is independent of the Arch base system. Depending on your hardware, kernel level support may be available and installed, while your display server software may be the component having problems and not the kernel or other system configurations. Just an idea to poke at, some setups and hardware support can break at different points based on the way you've set up your system with associated packages/dependencies.
