[Nouveau] 4K ~ 3840x2160 resolution and frame buffer support

[James Lehman]

Hello. I hope this is in the right place.

I just built a new machine and installed Xubuntu and I'm still figuring 
things out.

I'm interested in working with The Linux Frame Buffer.

Many years ago, I started a project called ezfb and I would like to 
continue developing it on a machine capable of 4K.

Is it possible to have a frame buffer that does 3840x2160 ?

With nouveau installed as my video driver, I can get to a frame buffer 
console of 1920x1080, but I am limited to that resolution in Xfce as well.

With a proprietary nVidia driver installed I can get to 4K in Xfce, but 
my frame buffer is 640x480, 4 bit color. When I try fbset to change 
anything, it doesn't work.

I have not even bothered to try my code so see of any of it can actually 
work in the frame buffers I get.

Still scratching my head....

Thank you for your time.

James.
