It would seem (from what i can find quickly) that wayland will indeed use the primary one by default. This can be fixed if you can just disable the intel one in the bios?
I have no option in my BIOS to disable Intel Graphics. There is no option for graphics in my BIOS.
If you want continue with Xorg, start by making sure that you have the package installed xorg-x11-drv-amdgpu . And then have a look through the wiki link for any other information.
Nope, I want to stay with wayland. Just wish there was better documentation.
Let us know what you want to do. (It would seem disable in the bios would be the fasted option all round)
I want to continue with Wayland with my AMD card as the primary display adapter.
