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.

HDMI with nouveau is limited to 165mhz unfortunately. This is
incorrect (the hardware can do more), but nevertheless, that's the
present limit. If you can connect the screen over dual-link DVI or DP,
you should be able to get the full resolution.

Thank you for your quick reply.
I have a Gigabyte GT-730 2GB card hooked directly via a high quality HDMI
cable to a 65 inch Samsung curved screen LCD 4K monitor.
I'm not sure what I am looking for in dmesg and xorg log.
Please advise.
I have built the 3.19.8 kernel and enabled frame buffer support.
I can see 7 out of the 8 penguins when I boot.
My ultimate goal is to be able to boot to a 3840x2160 32 bit (frame buffer)
console.
Then go into Xfce, or not, as needed.
I like to write frame buffer apps that run in the console.
Thank you.

If you only get 1920x1080 in X, chances are that nouveau doesn't
believe it can do 3840x2160 for one reason or another. There are a
number of reasons why this might be the case, please provide dmesg,
xorg log, and information on how the monitor is connected (including
any A->B type adapters).

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.
