After some days to find the correct way to install SO and Drivers
This is the script that I use - more or less - from scratch Ubuntu 20.0.4 install:

sudo su
add-apt-repository ppa:graphics-drivers
apt-get update
apt upgrade
apt install nvidia-driver-450
apt autoremove
echo "blacklist nouveau" > /etc/modprobe.d/blacklist-nvidia-nouveau.conf
echo "options nouveau modeset=0" >> /etc/modprobe.d/blacklist-nvidia-nouveau.conf
echo "Section \"ServerFlags\"" >> /usr/Xhare/X11/xorg.conf.d/10-nvidia.conf
echo "    Option \"AllowIndirectGLX\" \"on\"" >> /usr/Xhare/X11/xorg.conf.d/10-nvidia.conf
echo "    Option \"IndirectGLX\" \"on\"" >> /usr/Xhare/X11/xorg.conf.d/10-nvidia.conf
echo "EndSection" >> /usr/Xhare/X11/xorg.conf.d/10-nvidia.conf
update-initramfs -u

I’m blocked at this point:

  • nvidia-smi works as aspected with xorg on running process
  • nvidia-setting works pretty well, that recognize GPU, but lack some configurations
  • glmark2 report is using GL_VENDOR VMware, Inc. / GL_RENDERER llvmpipe (LLVM 10.0.0, 128 bits) with poor score
  • unigine valley benchmark run at 1FPS

this is my nvidia-bug-report:

what I missed to run correcly the drivers?

found it! AMD Renoir is still not supported on official mainstream ubuntu 20.0.4 kernel.
After install kernel 5.8.7 system works better.

External monitor continue not working until I set NVIDIA as main GPU adding on /usr/share/X11/xorg.conf.d/10-amdgpu.conf the option “PrimaryGPU” “no” and also on /usr/share/X11/xorg.conf.d/10-nvidia.conf the option “PrimaryGPU” “yes”

now benchmark report nvidia GL driver is used.
