Nvidia driver installed but not used

I have a problem with nvidia drivers, I installed the packages but my GPU is not used.
This is what I installed:

sudo pacman -S nvidia-dkms nvidia-utils lib32-nvidia-utils nvidia-settings vulkan-icd-loader lib32-vulkan-icd-loader
sudo pacman -S lib32-mesa vulkan-intel lib32-vulkan-intel vulkan-icd-loader lib32-vulkan-icd-loader

With nvidia-smi I have this, look like it's off.

[peanutstick@peanutstick x264]$ lspci -k | grep -A 2 -E "(VGA|3D)"

As you can see I have GP107M [GeForce GTX 1050 Mobile].
But when I do this I have an error.

[peanutstick@peanutstick x264]$ nvidia-settings 

ERROR: Unable to load info from any available system

I've tried to set up an automatic config but my system don't restart and I have to use a bacckup.
I tried to follow the instructions in the wiki.

Re: Nvidia driver installed but not used

"Tried with the wiki" - what?
Read https://wiki.archlinux.org/title/NVIDIA_Optimus and make up your mind how you intend to use the GPU.
Do *NOT* use nvidia-settings or nvidia-xconfig to generate an Xorg configuration.

Sorry for my english.
Ok thank, yes I saw that, after an auto config I was stuck with a black screen when I reboot.

Re: Nvidia driver installed but not used

I would like to use NVIDIA GPU when needed and keep it powered off to save power.
So I will use Prime render offload.
There is what I done:

/etc/X11/xorg.conf.d/10-nvidia-drm-outputclass.conf

Section "OutputClass"
    Identifier "intel"
    MatchDriver "i915"
    Driver "modesetting"
EndSection

Section "OutputClass"
    Identifier "nvidia"
    MatchDriver "nvidia-drm"
    Driver "nvidia"
    Option "AllowEmptyInitialConfiguration"
    Option "PrimaryGPU" "yes"
    ModulePath "/usr/lib/nvidia/xorg"
    ModulePath "/usr/lib/xorg/modules"
EndSection

I use lighDM

/etc/lightdm/display_setup.sh

#!/bin/sh
xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto

I done a chmod +x on the file.
In the file /etc/lightdm/lightdm.conf:

display-setup-script=/etc/lightdm/display_setup.sh

Them I reboot and check with mesa-demos:

glxinfo | grep NVIDIA

But nothing appear.
Wine don't work anymore so I will use a backup and retry.
