Re: Replacing nvidia card, with Amd - can no longer boot.

[Esteban L <esteban@little-beak.com>]

Solved.

Simple, yet simple things are the hardest to solve sometimes.

1. With the nvidia card still installed, need to boot in single user mode. Press e at grub.

2. Add 1 at the end of linux line, after ro

3. Press F10 or ctrl-x, to boot in single user (text) mode.

This is required. You can't have x already loaded, or you will get an error message about nvidia-drm.

4. Navigate to you nvidia installer, something like NVIDIA-x86_64-1895.run

Run it WITH the flag --uninstall

sh NVIDIA-x86_64-1984.run --uninstall

That is the trick!

What I don't know is how to solve this issue had the nvidia card failed :-( i couldn't do much of anything.

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??

Most NVidia users taint their installation with non-FOSS NVidia video drivers.
These must be removed according to the instructions that accompanied installation,
as they replace at least one library that prevents all competent FOSS DDX from
working automagically, or at all.
