How to change my Nvidia GPU to an AMD GPU?

[AjayTV]

I thought I simply have to take out the Nvidia GPU and install the AMD GPU but once I do that I can’t reach the login screen so I switch back to my Nvidia GPU and it works. I found this site: AMDGPU - ArchWiki
but to be honest with you I feel overwhelmed just from trying to navigate the site.
Any advice would be appreciated.

Merry Christmas!

Hello @AjayTV

To put it simple: You have to remove/rename the xorg config which calls nvidia specifically.

Find it:

find /etc/X11 -name "*.conf"

The amd gpu should work then in general (since auto detection), but the nvidia card will not work then.
