I'm here just to remind everyone that Wayland was first announced in 2007: ~13 years ago.

And Nvidia has been sabotaging it ever since.

Hell, even Canonical tried to sabotage it by starting their own NIHing alternative but thankfully Intel told them promptly to fuck off if they expect them to support it.

Jokes about the year of Linux on the desktop come to mind, but complex software that needs to track moving targets should be allowed time to mature.

Is this just for gaming/etc or does the desktop environment also cause issues if you’re just trying to use it as a highly parallel compute device?

The DEs are moving towards wayland.

That doesn’t really answer my question.... rephrased: all I do with high-powered GPU’s is Remote-SSH into hosted Linux machines and run ML jobs. Does this wayland thing have any impact there?

It should answer the question because the use case which you are stating (didn't before) is that you're using a headless environment. Which means you aren't using a DE.

IF you are using a server with a DE then it answers the question about how yes it does affect you because you are using a DE.

In either case, it isn't "just for gaming"
