I can’t find the mistake in my installation. nvidia-smi gives “No devices were found”.

I think your title is incorrect. The Driver itself is loading, but it cannot find any GPU devices.

I am having the same issue on Ubuntu 18.04:

Nvidia-driver-470: nvidia-smi shows "No devices were found" on PC Ubuntu 18.04

== The problem == After upgrading to nvidia-driver-470, our Cuda applications are not working, and nvidia-smi is not finding any GPU device: me@bimba:~$ nvidia-smi No devices were found The exact same issue happened on 2 separate PCs. Previously we were using nvidia-driver-465 and it was working fine. After upgrading to nvidia-driver-470, I couldn’t downgrade back to 465, because the 465 package in the apt repo is a transitional package for 470: me@bimba:~$ apt show nvidia-driver-465 Packa…

I’m having the same problem on Ubuntu 20.04 too, did you manage to solve it? How?

I got it working by purging all nvidia related packages, installing “nvidia-driver-470” and disabling secure boot in MOK before boot (I think that was the problem after all)

sudo apt purge *nvidia*
sudo apt purge '^nvidia-.*'
sudo apt purge '^libnvidia-.*'
sudo apt purge '^cuda-.*'
sudo apt-get install nvidia-driver-470
sudo reboot
