I am trying to configure Ubuntu 20.04 to use the integrated Intel graphics for xorg and leave the NVIDIA GPU as free as possible to CUDA programs. Such that nvidia-smi shows no process using the GPU.

I am following the answer in

fresh 20.04 install with nvidia and iGPU.. only get iGPU resolutions

(and links therein)

At one point it is recommended to delete the file:

xorg.conf.d/11-nvidia-offload.conf

which on my Ubuntu 20.04 system is not present. I see only:

Should I delete 11-nvidia-prime.conf ?

What I've done so far:

  1. sudo prime-select on-demand
  2. created /etc/X11/xorg.conf
  3. Upon reboot will add the kernel parameter 'nogpumanagaer'

I took the risk and rebooted (with the added kernel parameter). It worked, no need to delete 11-nvidia-prime.conf.
