I have Dell model XPS 15 and just installed a fresh Ubuntu 22.04.1 LTS. I have lots of problems installing it at first but after some time I was successful. I also tried to install the "nvidia-drivers-515" drivers. I had some problems with this as well but finally got it instlled.
Ubuntu still seems to be using the integrated card instead of the Nvidia.
This is some output.
➜ ~ lspci -nn | grep -E 'VGA|Display'

The system recognize both cards but integrated one is being used.

From the following output Nvidia seams to be sleeping or im missing something?

Why both cards are active?
How can i make sure that I'm using the Nvidia and the drivers are working properly?
