Answer 1

I was facing same problem and I'm posting here my solution.

In my case NVRM version was 440.100 and driver version was 460.32.03. My driver was updated by sudo apt install caffe-cuda and I didn't notice that time but I checked it from /var/log/apt/history.log. By following my NVRM version I just used sudo apt install nvidia-driver-440 but it installed 450.102, I don't know why it installed other version and nvidia-smi is showing 450.102.04.

Anyhow after rebooting my PC everything including cuda is working fine now.

I didn't remove/purge anything related to nvidia driver. Version 460.32.03 was uninstalled automatically by running sudo apt install nvidia-driver-440

Answer 2

For me, this solution from NVIDIA forums solved the issue.

Run sudo apt purge nvidia* libnvidia*

Then sudo apt install nvidia-driver-520

Answer 3
