IIRC, I got the amdgpu module to load and it still didn't detect the graphics card right. How can Debian be so old? I thought I could use it for workstations and servers, but when it can't even work right with a relatively old graphics card, its usefulness becomes very questionable --- and it leaves me without a good alternative.
