Switch from Nvidia gpu to Amd gpu

Still not very explanatory.

What have you done, what are you trying to do?

At least according to the inxi output you have the nvidia detected … possibly because thats the gfx profile still installed.

In any case you can try to gain ccess via TTY or runlevel3

From there I would check

mhwd -li -l

PS.
Both the kernel and the BIOS are pretty old.
