No device detected ; Ubuntu 20.04

Graphics / Linux Linux

I have an Ubuntu (20.04) VM which has been working perfectly well for a year. Recently, for whatever reason the 1650 Super is no longer being detected by the VM.

When I run nvidia-smi, I get the following

jay@mediapc:~$ nvidia-smi
No devices were found

I’ve tried rebuilding a new VM with the following commands

sudo ubuntu-drivers autoinstall

And I still get No devices were found, when running nvidia-smi

This is what I get when I run ubuntu-drivers devices

jay@mediapc:~$ ubuntu-drivers devices

What’s weird is, when I switch my VM to use another GPU (970), nvidia-smi does show results.

So, thinking that this is a GPU issue, I tried to use that GPU in a Windows machine but the Windows machine is able to detect and use the 1650 Super GPU perfectly fine.

Any ideas on how I can fix the issue?

The logs show a msi notebook with a rtx2060 which is working fine. Did you attach the wrong file?

I am not sure what happened there, but try this one:

Those are the correct logs.
It seems an update of the driver (470.82->470.86) triggered this. Before driver 465, the hypervisor had to be hidden for consumer graphics cards, now this (should) work without it. I suspect this has broken in the 470.86 driver. Please try upgrading the driver to either v495 or to v470.94.
