Hello, I try to use RTX 3060 in laptop after installing driver using ‘Software & Update’ application in Ubuntu 20.04.
I can check my GPU model.
However, ‘nvidia-smi’ command gives ‘NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.’ message.
I reinstalled Ubuntu, NVIDIA driver several times. Nevertheless, issue is still existed.
There are several things I check about that problem.
1. Additional Drivers session shows ‘Unknown’ for GPU name
2. Can not change from internal graphic card to external
3. Nvidia x server settings only shows prime profiles
Attached is result of running 'nvidia-bug-report.sh’

I am looking forward to some advice.
