Question

I need help i have an nvidia and intel igpu graphics

(on desktop)
i wanna get my output from intel igpu but use nvidia as opengl and vulkan renderer
the problem is that intel graphics works fine but whenever i install the nvidia drivers the xserver just won't start anymore
how do i fix this? (and yes i've searched this before asking)
i use arch btw
