I asked on the IRC and a person told me Guix System often works on almost all machines and I should check /var/log/messages, but then the person disappeared, but I have the log. I don't know if it's a bug or that's my nonfree hardware, so I posted the issue here. --Jan


I suppose this is a common problem with AMD GPUs.  I had more success
on my old AMD GPU after changing /etc/config.scm to use

(service slim-service-type)
(remove (lambda (service)
          (eq? (service-kind service) gdm-service-type))
        %desktop-services)

or similar and then reconfiguring, see `info guix`, section on
slim-service-type.

In order to edit /etc/config.scm using the virtual console, you may
need to when booting in GRUB press e and add modprobe.blacklist=radeon
or modprobe.blacklist=amdgpu to GRUB’s linux line.
