Hello, I installed Guix System on a new machine, which displays on a 4K (3840 x 2160 pixels) monitor.
Unless I go to the GRUB command prompt with 'c' at boot and type 'insmod all_video', the video cuts early after booting a GRUB entry with 'No suitable video mode found', or similar. I think we should include this GRUB module in our default GRUB package/configuration. Maxim
