I’ve found some short descriptions about how to switch GPU manufacturers on Linux, which is basically just uninstalling anything related to Nvidia, i.e.:
pacman -Rns nvidia{,-utils}
and install the mesa/radeon package(s) as outlined in the archlinux docs.
However, I’d like to know beforehand if there’s anything else to make sure before switching? I just want to make sure I don’t mess up my computer and get the transition as flawless as possible.
Manjaro should have installed mesa by default so you don’t need anything for swithing GPU to AMD. Just plug and play After swithing you may want remove proprietary nvidia drivers – use mhwd for that.
I’m going to give advice that is good for a beginner. First, you are not using Arch, you are using Manjaro. The best way to switch without issues is to change your video cards, then reinstall a new ISO. Nice and clean, just back up all your data and it should only take about 1 or 2 hours depending on your situation.
Lets try this again. First regardless of dev claims the base isa still Arch. Second if you are switching from nVidia to AMD then no need to rerun the OS. Third most people when they do a fresh install take a lot long than THREE hours to get everything to their liking including getting the software they want installed.
