I can't quite follow why you need rescue mode. After the login/password ( Xorg not running) in your sequence above, just don't run startx. Then edit the sources list, adding non-free to it. Now run apt or apt-get to update, and install the package. $ sudo apt-get update $ sudo apt-get install firmware-amd-graphics I've attached my sources.list as a pattern, though you can leave out the lines starting with deb-src. Cheers, David.
