Nvidia Drivers is not loaded

Hello everyone, I’m having driver issues with my laptop, an HP 15-r237nl running Ubuntu 20.04.1 LTS. I’ve installed the “Driver metapackage from nvidia-driver-455” through the “Additional Drivers” GUI program, but when i try to executenvidia-settings this is the output

"ERROR: NVIDIA driver is not loaded

ERROR: Unable to load info from any available system

I have secureboot disabled.nvidia-bug-report.log.gz (110.7 KB)

You have a Fermi-based gt820m which is only compatible to driver version 390. Please install that one through “Additional Drivers”.
