How do I make Manjaro use my NVidia GPU instead of my Intel UHD Graphics one?

[arenc]

I just checked out the Info Center and it seems that Manjaro is using my Intel UHD 630 Graphics card. I have a Nvidia GTX 1650 GPU but it seems like Manjaro isnt using it. How can I set it so Manjaro uses my actual better GPU? (nvidia)

I would add an image here, but for some reason I cant.

Hello. Thank you for the answer but as far as I can understand this document shows how to use the other GPU for specific applications. How can I set it as a default so every application uses my Nvidia GPU?

You could make use of Optimus-Manager and switch to the desired GPU or use it as render-offload. I suppose you have the hybrid drivers installed.

Yes, I do have the video-hybrid-intel-nvidia-455xx-prime driver. Thanks for your answer, going to try it out

Hello again, I have installed the optimus-manager package from the AUR but even though I enabled the service using systemctl enable optimus-manager.service it still is giving the error No state file found. Is optimus-manager.service running ? What can I do to fix this?

OK, I have enabled it but now it gives me another error.

Hello again! I have fixed the issue by downloading an AUR package called optimus-manager-qt and then using that to switch to my Nvidia card. Here are some things that happened:
First switch, nothing changed.
Rebooted.
Got stuck waiting on boot.
Hard reset 2 times, then it booted. But this time it was using Intel.
I clicked switch to Nvidia again, logged out and it worked!
