hmm, one last thing that you can try might be this : modprobe.blacklist=radeon modprobe.blacklist=nvidia modprobe.blacklist=nouveau modprobe.blacklist=vesa loglevel=7 amdgpu radeonsi amdgpu.dc=0
But Pop doesn‘t use grub in their live medium. It boots directly to the Live-Desktop. I will try to find the Parameters there as there have to be a boot config or something i guess?
EDIT : It uses Systemd-boot, maybe this is why it’s working, because maybe grub is somewhat buggy on your system, idk. You could try to boot with Systemd-boot or rEFInd your EOS system (unfortunately I don’t know how to configure them)
So i should look for a cfg-file for systemd-boot instead?
Edit: I saw your edit too late.
Can this be a grub error? On both, live iso and my (before the gpu-breakdown) full functional installation? I am really confused
It’s not a driver issue. I have the same card. The firmware and I believe the mesa version on the April ISO is too old for this card. I can’t boot that ISO either and it stops in exactly the same way.
It’s quite a relief that this is a “known” problem. I have read through your solution but I am not sure that I have understood everything correctly, I fear.
From what I read is that I need a development-version from EOS as the official release of April does not work, right? And the GRUB from the April Live ISO does not have a button that will let me start calamares.
So, first question: Where can I get my hands on a dev release from EOS
and second question: How can this help me with my previous installed EOS? Am I supposed to reinstall my system with this dev-release then?
