I am not exactly sure how you configure two GPUs from two different vendors, as I haven't done that myself, but I do know this: many machines has a setting in the BIOS (or, I would assume, UEFI) that lets you select to use either on-board or discrete graphics. You may want to check that. Also, there are proprietary drivers available for nVidia cards. Those drivers have a GUI for configuring them, which you might find easier to use. I found this link, that might help you: https://wiki.debian.org/NvidiaGraphicsDrivers It doesn't appear that these instructions use the latest available drivers at the time, but those that have been tested with your version of Debian, and that is probably a good thing. If you, for some reason, want the latest drivers, you can do a search for "nvidia linux drivers", and I am sure you will find them easily enough. Be adviced, though, that messing too much with graphics drivers can quite thoroughly mess up your X configuration, so you might want recent backups :) I hope this is of some help to you.
