How to communicate with communicate with nvidia driver on ubuntu20.04

I want to use the command: “nvidia-smi”.

However, I don’t know how to communicate with communicate with nvidia driver on ubuntu20.04.

Please help me.

OS: linux ubuntu20.04
GPU; GeForce RTX 2080 SUPER

Can you please describe your problem in more detail including any error messages you’re getting, and run sudo and attach the resulting bug report log file if possible?

If the problem you’re running into is that nvidia-smi says that it “has failed because it couldn’t communicate with the NVIDIA driver” then that indicates that there is likely a version mismatch between nvidia-smi and the kernel modules loaded into your Linux kernel. This kind of driver installation problem seems to be quite frequent on Ubuntu recently so looking around for similar threads such as this one might help, or you could try contacting an Ubuntu-specific forum for help with driver package installation problems.
