For the time being I got it working by removing all nouveau selections
in "make menuconfig" and by emerging
"x11-drivers/nvidia-drivers"
Version 440.82.

Back on the latest Linux Kernel. Feels great ;).

Not sure why you bother asking questions when you're just going to
dump nouveau anyways. This is the second time I've answered your
questions on this very topic, I think it'll be the last too.

I will try again with the next Kernel release. So far I spent a lot of
time and I did not manage to get it to work. And I need my graphical
Linux Desktop.

I am a Nouveau user since day one.

This may also be a Gentoo/Funtoo Issue. I will keep you posted, if I
have any success.

Actually, what I will try next is emerging
"x11-drivers/xf86-video-nouveau" Version-1.0.15-r1. It that works for
Nvidia, I guess it will also work for Nouveau. ;)

I would have preferred to have it all in the Kernel but that does not
seem possible.

I tried again and removed the Nvidia-Drivers with

sudo emerge -C x11-drivers/nvidia-drivers

and installed

sudo emerge x11-drivers/xf86-video-nouveau

this works with Kernel 5.7.0!

~> inxi -G
Graphics:  Device-1: NVIDIA GP107 driver: N/A

           OpenGL: renderer: Rasterizer v: 2.1 Mesa 19.1.4

but now xrandr no longer works.

~> xrandr -q
