Arch Linux not using the Nvidia GPU.

This happened after I installed Steam. My gaming experience became laggy and the laptop became quiet, that happens when my Nvidia GPU isn't used. I decided to check Mission Center and the Nvidia GPU isn't there!

I tried re-installing Arch Linux and the first time I boot, it used the dGPU but after a reboot it stopped using the Nvidia GPU.

What can I do?

My specs:

Nvidia RTX 3050 Laptop GPU
12th gen Intel Core i5 12500H

Output of inxi -G:

Graphics: 
  Device-1: Intel Alder Lake-P GT2 [Iris Xe Graphics] driver: i915 v: kernel 
  Device-2: NVIDIA GA107M [GeForce RTX 3050 Mobile] driver: N/A

  • Don't know Arch but if it's anything like Debian-based distros, when you install the Nvidia drivers, it also installs Nvidia X Server Settings, a Nvidia control panel of sorts. With it you can select the profile you want (iGPU or dGPU Nvidia), reboot, done! Commented May 27 at 14:14
  • Please post the output of inxi -G (you might need to sudo pacman -S inxi first). Also, what is "Mission Center"? Have you followed the Arch documentation? Are you dual booting the system with anything else? Commented May 27 at 16:23
  • terdon yes i did followw the documentation, when i did it my linux wasnt loading. Mission Center is basically task manager like on windows. I didnt dual-boot. Output will be in next comment Commented May 27 at 17:20
  • Thanks. Just add the information to the question directly (I already did it). Your inxi output shows no driver for the nvidia card. You will need to install one as described in the relevant Arch page: wiki.archlinux.org/title/NVIDIA. If that doesn't work, you will need to explain exactly what you did and how it failed.

  • I installed the drivers correctly. nvidia-smi tells that drivers work. while im playing games i still have low fps for some reason. The Nvidia GPU is quiet. I did sudo pacman -S nvidia nvidia-utils lib32-nvidia-utils nvidia-settings which installed drivers, rebooted and still low fps. Commented May 27 at 18:05

I re-installed drivers; that's the solution.
