System doesn't use Nvidia Gpu

Graphics / Linux Linux
1

OS: Kubuntu 22.04 LTS x86_64
Host: Asus TUF f15 FX506LH
Kernel: 5.17.5-76051705-generic
GPUs: Intel CometLake-H GT2 and nvidia gtx 1650

problem: System doesn’t properly see nvidia GPU, neofetch displays the GPU as “NVIDIA 01:00.0”, both steam and standalone games don’t use nvidia. Im using driver (510.73.05], on 470 it didn’t work either. I tried using older kernel but it also didn’t work.

Here is nvidia-smi output:

here is nvidia-settings output:

I’ll paste nvidia bug report in the comment.

I checked a ton of forum posts. non seem to describe a similar problem nor do they provide any solutions that would help me.

You’re in offload aka on-demand mode. You’ll have to explicitly tell applications to run on the nvidia gpu:
https://download.nvidia.com/XFree86/Linux-x86_64/495.44/README/primerenderoffload.html

If you want everything to run on the nvidia gpu, use
sudo prime-select nvidia
and reboot.

  1. It looks like on demand mode but no matter how i try it, via sudo prime-select, via nvidia-settings or via making an app load using nvidia it didn’t work.

I reinstalled the system and it worked, i don’t have a clue what could have broke it becouse fresh install got every update that was on the broken one and i loaded a backup and it is still working.
Thanks for the help tho.
