Friday , May 28 unattended update broke amdgpu DKMS building
I was on unattended updates and Friday afternoon the Radeon RS780 machine rebooted into
minimal resolution mode and can no longer go to full HD resolution.
I put the disk into an old laptop with intel GPU where the DKMS modules amdgpu cannot
build properly, thus Radeon machines are screwed.
"/etc/udev/rules.d/70-amdgpu.rules:1 Invalid operator for GROUP."
was what the protocoll had to say.
