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

[James Lehman]

Oh! Bummer.

Thank you again for getting back to me.

My video card only has one HDMI, one digital video and one analog VGA port.

So I guess I'll have to wait for future nouveau developments.

I don't really need high speed graphics, openGL or 3D.

I'm not a gamer. I just like to write my own code to plot pixels.

Uh..... I hate to ask this of the nouveau development team, but.....

Is there any way to use the nVidia proprietary driver to get a 4K Linux 
Frame Buffer?

Thanks again.

James.
