Setting Option "PrimaryGPU" "yes" in the nvidia.conf does nothing with Wayland

Hi. I have been trying to set my NVIDIA GPU as the primary GPU, but even with the directions here, it still defaults to my Intel Mesa GPU.

Please post the output of lsmod | grep -Ei 'nouveau|nvidia', inxi -Fzx, and cat /etc/X11/xorg.conf.d/nvidia.conf. We need to have info so we can potentially track the problem.

Here is all the outputted info:

As you can see by the output of the nvidia.conf file #This file is provided by xorg-x11-drv-nvidia it is intended for use with the xorg display manager.

You are however using wayland

  Display: wayland server: X.Org v: with: Xwayland v: 22.1.2
    compositor: gnome-shell driver: gpu: i915 resolution: 1920x1080~144Hz

so it does not manage the GPU the same way.

You will have to switch to xorg if you want the system to use the nvidia GPU only. That is done by using the gear icon in the lower right of the login screen where you enter your password.

You do, however, in gnome have the ability to right click on the icon used to launch an app and select to use the discrete GPU for that app. It only works that way one app at a time and there may be issues with having both wayland and xorg active at the same time.
