It should be pretty easy. Technically you shouldn't have to do anything, but you'll want to remove the nvidia packages. You probably already have Mesa installed as a dependency for other things. Perhaps not all of the parts you need (Arch splits the mesa packages)

I would remove your Nvidia packages after installing the new AMD card.

You will probably need to install vulkan-radeon

This is mesa on Arch (their distro packages)

libva-mesa-driver, mesa, mesa-vdpau, opencl-clover-mesa, opencl-rusticl-mesa, vulkan-intel, vulkan-mesa-layers, vulkan-radeon, vulkan-swrast, vulkan-virtio

This is lib32 mesa:

lib32-libva-mesa-driver, lib32-mesa, lib32-mesa-vdpau, lib32-opencl-clover-mesa, lib32-opencl-rusticl-mesa, lib32-vulkan-intel, lib32-vulkan-mesa-layers, lib32-vulkan-radeon, lib32-vulkan-swrast, lib32-vulkan-virtio

You certainly don't have to start over :-)

P.S. You might need to remove Nvidia's xorg.conf file IF you have generated one (e.g. with nvida-xconfig)

For AMD, you probably don't want/need one at all. Rename it if present.

/etc/X11/xorg.conf

Amazing, thank you! :D

I'm genuinely so excited for this, a majority of my issues with linux since I started my journey in 2018 have been related to me having an Nvidia card. I can't wait to get on wayland! fully supported too!

By the way, a nice thing about Arch is that they have wikis for everything:

https://wiki.archlinux.org/title/NVIDIA
https://wiki.archlinux.org/title/AMDGPU

You might catch a tidbit or two if you skim those (maybe read the Nvidia one backwards )

Oh, something I forgot to mention. You may have heard about how awful it is to switch away from the proprietary Nvidia driver. There was a time when you may have had to reinstall some Xorg and Mesa packages, but it's not like that anymore. (i.e. don't get hung up on old info still floating around)

That's because we use dispatchers for the hardware specific components of OpenGL and Vulkan. We use libglvnd (GL vendor neutral dispatch) which was specifically implemented for the Nvidia case, because that used to break Mesa.

Vulkan uses the vulkan-icd-loader to dispatch "installable client drivers" for your vulkan implementation.
