My graphics card model is 3080, system is Ubuntu 18.04, and the driver version is 470. When I run the command “lspci | grep VGA”, I cannot see any information about the Nvidia graphics card. When I run the command “nvidia-smi”, I receive the error message “NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.” I have tried reinstalling the system, but the issue persists. I have also noticed that the graphics card’s light is on.
ubuntu@ubuntu18:~$ lspci | grep VGA
c2:00.0 VGA compatible controller: ASPEED Technology, Inc. ASPEED Graphics Family (rev 41)
ubuntu@ubuntu18:~$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
When I ran “nvidia-bug-report.sh”, I saw the message “PKCS#7 signature not signed with a trusted key”.
