$ inxi -G   
Graphics:
  Device-1: Intel WhiskeyLake-U GT2 [UHD Graphics 620] driver: i915 v: kernel
  Device-2: NVIDIA GP108M [GeForce MX250] driver: nvidia v: 510.54
  Display: wayland server: X.org v: 1.21.1.3 with: Xwayland v: 22.1.0
    compositor: gnome-shell v: 41.4 driver: X: loaded: modesetting,nvidia

  OpenGL: renderer: Mesa Intel UHD Graphics 620 (WHL GT2)
    v: 4.6 Mesa 21.3.7

I’m not sure if Xorg is configured correctly and what config files it is using.
Need some advice.

By default you can offload applications to the nvidia card:

__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia command

or

prime-run command

What is the problem?

nvidia-smi shows you the loaded driver version and inxi as well, so you’re good to go.

Oh, i apologize i did not know this command. I look in Settings > About, X is loading on Mesa Intel® UHD Graphics. Two games on Steam failed so i thought there is a problem with nvidia drivers.

Thank you so much for your time.
