I've tried to follow this wiki NVIDIA/Optimus to set nvidia optimus up. I've switched from fx86-video-intel to fx86-video-modesetting by adding the following lines into my make.conf file. 



VIDEO_CARDS="intel i965 iris nvidia"

INPUT_DEVICES="libinput synaptics" 



Originally after I did this X server wouldn't start so I made a post asking for help.

But nvidia offloading didn't work so I removed all the files under /etc/X11/ and /usr/share/X11 and tried to write my own X config files to make it work, but I wasn't successful at my attempt on getting nvidia offloading to work so I had my friend send me his config files because they were gentoo stock config files, as I forgot to make a backup of my original config files non intentionally.



I've tried to follow this guide as described here but I got a black screen and a segfault.

I found this Xorg.0.log but I'm unsure if it's the same one from the image that I linked because I'm using modesetting right now.

I have an ASUS X541nc laptop, xrandr doesn't detect my nvidia card. 



xrandr --listproviders

Providers: number : 2

Provider 0: id: 0x45 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 3 associated providers: 0 name:modesetting

Provider 1: id: 0xb1 cap: 0x0 crtcs: 0 outputs: 0 associated providers: 0 name:modesetting 



But the nvidia-smi does

How to get nvidia offloading to work properly, right now I can get only intel to work with the default gentoo configuration without xorg.conf file that tries to setup nvidia, deleting that enables intel modesetting to be used by default.
