Harvey nice fool proof method. But it does not work when replacing a AMD GPU by a new NVIDIA 1660 card. As you can not enter the GUI but stay on a tty.
After hardware change, reboot the system, boot stops with telling me nouveau finds unknown chipset 1680 00ai.
The grub 'e' change nomodeset did not work. Starting from Solus Live CD did not work. And the hw is ok as a dual boot on same machine with latest NVIDIA driver works (after some hassle).
Now I try to install the nvidia developer drivers from the command line, I would really need a good write up how to do that.
eopkg the developer versions of the nvidia drivers helped, but, ....
The network icon in the right bottom corner now tells me Networking disabled, but it is not as I am via wifi connected to the home router to internet to write this Edit.
The USB ports stopped (all of them, mouse, keyboard, wifi) and I had to do a hardware reset to reboot to recover.
Any help or suggestions would be highly appreciated.
Kind regards,
