Blender supports cuda for much of its gpu work. It will work with amd. And there are projects allowing gpu rendering via amd. But they are (and have been for a while) a long way behind the cuda stuff.

For major rendering projects nvidia is still the fastest set up to use.

AMD. Unless you need blender.

I think you underestimate the hate.

For the organisations that want to deny the ideals suggested. Using software under such a licence would lose them support. So when developers select such a licence. The software itself gets recognised as such. Meaning any shitty organisation using it gets labeled unacceptable to their very user base.

So requiring the acceptance of these facts would have the same effect as anything else.

Ssh x11 forwarding has been a popular system for decades. (Id love to know if wayland options exist yet)

But as other have suggested you need x11 on both systems. It is very inbuilt into the way x11 was originally designed. (From back when we had huge shared servers and dumbish xterm workstations. This means it was designed to do much of the work on the server end with the display being the lower cost less able system.

It will work on a pie. But not with the lite os system as designed.
