Planning to upgrade GPU from Nvidia to AMD. Any pitfalls I should know about? (reddthat.com)

I'm running CachyOS, and having an Nvidia card, I'm using their Nvidia-specific kernel. I know this 3060 won't last forever, and I'm planning to upgrade to an AMD card for a better overall experience.

Is there anything I should be aware of regarding the kernel or other compatibility when switching brands? Can I simply plug in the new one and run pacman -Syu?

Sidenote: I will plan around my PSU's output, so no need to advise regarding physical compatibility.

I switched from an Nvidia to AMD on catchy. There are instructions in the Wiki. https://wiki.cachyos.org/features/chwd/gpu_migration/

It worked for me with only one issue. When I booted up the first time, I had no signal to the monitor. No big deal, I just used SSH from another computer to install the AMD drivers and update the bootloader.

    Can you describe the process of installing AMD drivers in this environment? It should be plug and play, though admittedly this was my experience with EndeavourOS, I've not yet tried Cachy

    Look to the wiki link in my previous post for details, but the basic procedure was to uninstall the Nvidia drivers, shut down, install the new card, boot up and install the AMD drivers (there is a command to automatically detect your card and select the appropriate driver from the repos), and update the bootloader. I ended up having to do the second half through SSH, but otherwise a pretty painless process.

    That's really peculiar, both the kernel mode and userspace drivers are included by most disteos by default, but I can totally understand the nv proprietary driver making a significant enough change that users will need to address when swapping to Intel or AMD dgfx
