I recently bought an AMD Radeon RX 5700 XT card. Your 5700 might be too
new for Beowulf, I had to jump through some hoops te get my 5600 working
fully. Using the 5.10 kernel from Beowulf-backports, Mesa drivers and a
bunch of related libraries from a third party PPA, and a hack. I now
have 3D virtual worlds and dual screen working fine. No idea if any of
that will work for a 5700, since I don't have one.
