Currently my linux machine only can detect one monitor and seems to be running the bare minimum for graphic support. My system seems to recognize that the card is a Fury X but doesn't load any drivers for it. Mesa knows how to use the card anyways (which is strange) but it only can display on my first monitor.

Can/should I alias the card to use AMDGPU or does it not yet support the fury x? If so, how would I go about doing the modalias?

After some digging around on forums and in the kernel I discovered that Fiji isn't supported yet. Partial support is expected in 4.3 and full support in 4.4.

  • Testing confirmed that my gpu worked in 4.3 although the X server crashes when using amdgpu. – Tyler Scott Nov 20 '15 at 0:32
