Hello, Been beating my head against a wall. Had a fully functional and stable setup (9.x, stretch) with nvidia gtx 1060. Needed to swap out video card for an amd radeon rx 580. I knew it would be a problem, and sometimes I hate it when I am right :-(
Now, i can't boot. I hang on a "amdgpuxxxxx" to EFI VGA message. I don't have onboard video to fall back on. I could put the nvidia card back in, and I assume my machine would boot again. But, are there any steps on how I can get the amd driver installed, so that my system boots again?? -- Sent from my Android device with K-9 Mail. Please excuse my brevity.
