I don't know for sure, but that Radeon RX 580 card could be the
problem. I've set up a machine with Debian 9 and a Radeon R9 285 in the
past, and it was a pain to make it work -- it would not work at all
without the firmware blobs, and even then, I had to use a custom kernel
from AMD to get it working correctly...
If you have a 2nd (old nVidia would be the best) card laying around, I'd
suggest trying that -- if it works, you'll know the problem is with the
amggpu driver.
Good luck,
Maxim
