I recently installed Ubuntu 20.04 on a Dell XPS 15, which has a GeForce GTX 1650 Mobile / Max-Q. I installed version 440 because it introduced support for this card: https://www.nvidia.com/download/driverResults.aspx/146189/en-us
However, I don't think it's working correctly because if I run nvidia-smi, it cannot communicate with my card.
```
$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
```
nvidia-prime is on nvidia, and I rebooted since selecting it. However nvidia-config doesn't display the typical options you find when your nvidia card is active.

*** Update and likely underlying issue ***
Given that the workaround to disable Secure Boot made the driver work, I suspect that the issue is actually that when the drivers are installed and signed (with SB active), then the keys are either not imported correctly or mokmanager was not triggered to be loaded upon next reboot. This causes that even if trying to sign the dkms modules, SB finds them to be untrusted and won't allow the nvidia driver to be loaded. |
