Once you have installed and all what does an inxi look like?
inxi -Fazy
It seems you referenced mhwd profiles, so what does it say?
mhwd -li -l
PS.
You can also use paste services. ex:
inxi -Fazy | curl -F 'file=@-' https://0x0.st
PPS.
It was not clear if you were able to recover from the ‘bad’ nvidia install.
Assuming you had used mhwd for the install, you can remove it again from the tty, ex:
sudo mhwd -r pci video-nvidia
