Replace Nvidia GPU with AMD, should I reinstall the system?

Hello Everyone !
Hope you’re fine ?

Considering to replace my GPU (Actually Nvidia RTX 2070) to an AMD RX 7800 or 7900, I would like to know if it’s better to reinstall the whole system because there’s a lot of files for nvidia (kernel, grub, and many others…) Or is there a easy way to switch this without reinstalling Endeavour ?

It’s not for tomorrow so I’m not in a hurry, but I prefer to take informations before :wink:

Many thanks to all !

No need.

Just remove nvidia-specific packages and configs.
If you havent made any configurations then that would be nothing.
Packages you could search with something like

pacman -Qs nvidia

Aside from removing nvidia packages you may wish to add some amd packages;

sudo pacman -Syu amd-ucode lib32-vulkan-radeon linux-firmware-amdgpu vulkan-radeon xf86-video-amdgpu

Then just rebuild initram and refresh your bootloader.
If grub (and dracut) is correct then

sudo dracut-rebuild
sudo grub-mkconfig -o /boot/grub/grub.cfg

Remember to check that either of these are supported by the current drivers so you don’t have nasty surprise. There can be hiccups with AMD too. :slightly_smiling_face:

Yeah ok :slight_smile: I will try.

And last question :

Can I use another AMD card (RX550) temporary ? Because I need first to sell my actual Nvidia, then find a new AMD in second hand (not enough money for a brand new one…)
Is this the same drivers for all AMD cards ?

Many thanks :slight_smile:

Yes you can!

Sure. I am using a newer RX590 but still older compared to the current cards. It works fantastic.
