OK cool. When will it support nVidia?

inb4 it's nShitia who must support Wayland

Wayland compositors run entirely in userspace and do not interact directly with hardware drivers. If Wayland doesn't work on nVidia but X does, it's a Wayland problem.

Compositors do directly interact with the drivers though. The reason Wayland doesn't work on Nvidia is because Wayland uses an API called GBM(generic buffer management) to draw directly to the Linux VT. The Nvidia drivers don't implement that API, the API that both AMD and Intel drivers support. It very much IS an Nvidia problem and not the other way around. Nvidia tried to convince all the Wayland developers to use EGLStreams instead but no other drivers use(or even support) that API, everyone agreed on GBM except Nvidia. That's not Wayland's problem.

Iirc Nvidia also skipped the initial meetings that AMD and Intel attended, where it was decided they would move forward with GBM
