Linux wasn't very good 30 years back. But I'm glad you're using it now! So, you have Intel onboard and AMD PCIe card? It usually doesn't work to switch between onboard and a video card. Normally you use one or the other.
Certain laptops are capable of switching between 2 different video processors. So, I think you just got lucky with the 7470 card. For instance, on my lappy, I can have 2 displays. But I can't run 1 display off one video processor and the other display off the other one.
I have a desktop that has a card with 2 outputs, and it runs dual display off that card. But it doesn't work to run one display off the card and one off onboard graphics.
