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

2015-10-08 Thread James Lehman 

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.

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.

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.

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

2015-10-08 Thread 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.
