I have been trying to find the solution for this but I am stuck because I don't have enough time now.
I have reinstall my ubuntu 20.04, and the Nvidia x Server Settings worked, but the network adapter could not been seen by the os. I updated my kernel and now I have the 5.15.0-051500rc6-generic kernel, network adapter is working but I am in the same situation with Nvidia x Server Settings as I was before the reinstall of the os.
I open Nvidia x Server Settings and I see nothing as in the first photo.
I have tried to type nvidia-smi in and also the answer is in the second photo.
What can I do?
