Hi everyone! I just got a new laptop, but the Nvidia dedicated GPU doesn’t seem to be working. I installed all of the proprietary drivers but it doesn’t seem to use or recognize it or utilize it in any way. When I do fastfetch, this is the output:

I tried finding some solutions here and tried a bunch of stuff. Here is some more info in case it is helpful in finding out what’s wrong or how to fix it:

Could someone please help with this? It would be highly appreciated.

It would be appreciated if you would post the full output of inxi -Fzxx so we can get the big picture.

Also the linux harware db may have info about your laptop

It appears the nvidia driver is loaded.
Please explain in detail what is not happening and how you determined the dGPU is not functioning.
