switchable graphics An Update on using Arch Linux on my Legion 5

[archiso]

Since posting this almost a year ago I have uninstalled arch and just run windows for most of my school year because it "just works". But now with extra time on my hands over the summer I decided to go full send and do a clean install of just arch linux. I have found that most of my problems listed in my earlier post have been solved through kernel updates(The LTS kernel still doesn't work, but the latest kernel does). I am still faced with one major issue, switchable graphics, I can't get PRIME to work at all as my nvidia gpu won't show up in the nvidia driver settings and using hdmi or usb-c doesn't work due to those being connected directly to the dgpu. I did find this post on reddit from a while ago and they seemed to have the dgpu working but that could also be just that they switched over in the BIOS.

 

If anyone could help it would be greatly appreciated.

I have just tried to switch to the dgpu in the BIOS and sddm wouldn't start. I think I might just not have the correct drivers, I will look over the arch wiki again and try installing whatever it says there.

From looking over the xorg log I found this section. Something is wrong with my driver install I think.

I  do not have one.

You need one to make PRIME work, both arch and gentoo wiki's have decent articles on how it actually works, and what to do.

But first I need the dgpu to work at all.

What driver are you using?

Thanks for making me realize that I was using the wrong drivers, I was using proprietary nvidia with open-source amd. Switched to the proprietary amd and everything works!
