Set NVIDIA card as primary device for all applications in wayland

General system Kernel & Hardware

Hi, thanks to @pebcak I managed to enable wayland and NVIDIA together in Gnome. My problem is now that only gnome-shell is run on NVIDIA card and not all other applications. For example if I start google-chrome-stable, nvidia-smi output looks like this:

Is there a way to enforce any new window/software/whatever to run on nvidia card?

you mean this is an optimus enabled notebook with hybrid GPU? or a dedicated nvidia card in a desktop?

Yes, notebook with hybrid GPU:

[root@endeavouros ~]# lspci | grep -i --color 'vga\|3d\|2d'
0000:00:02.0 VGA compatible controller: Intel Corporation TigerLake-H GT1 [UHD Graphics] (rev 01)
0000:01:00.0 VGA compatible controller: NVIDIA Corporation GA104M [GeForce RTX 3070 Mobile / Max-Q] (rev a1)

still puzzles me how it is setup?
