Wayland and it's why it'll kill nvidia since it has 32 bit packages with the 64 bit ones I see when I do a Manjaro system update using pamac the 32 bit ones are quite large also. Maybe this will push Nvidia to go full 64 bit and be workable with Wayland unless the gpu's are so cheap "low quality" they cannot do it because of shortcuts in hardware for speed. This will be interesting to watch either way. Redhat will likely also be doing this or already have it Fedora is doing it now.
