Ryzen 1200

If you decide to venture in this direction then here are some important and not obvious points:

  1. You will need a GPU card. Just about all motherboards come with builtin video outputs and some kind of GPU, however because AMD Ryzen chips have no GPU unlike their common socket AMD APUs (which have a mix of GPU + CPUs) means that there is no GPU capability, hence the mobo graphics sockets will give you just a black screen.
  2. Reset your monitor from the monitor menu. I was trying to figure out why the edges of the screen were cropped and wasted time on a variety of exotic workarounds, only to find that a monitor reset did the trick.
BTW, Ubuntu works fine.
