Command nvidia-smi not found on my linux machine

This blog documents a strange thing that strikes me, and how I fixed it.

Problem

While I’m doing CS 285 homework, my own remote server ssh stopped its remote connection, caused me to go back home to check. After rebooting my ubuntu machine, I found that nvidia-smi is not found. I made some attempts, but it seems to not be an easy fix.

There’s something that relates to the kernel, I tried to reinstall the kernel, but it didn’t work.

It’s related to grub.

Thanks for being a part of my memory.
