Subject: bug#39607: Status: GRUB module all_video required to get video on 4K monitor
Date: Mon, 24 Feb 2020 09:08:27 -0500

Update, after debugging: the failure to find a working video mode had
nothing to do with the 4K monitor, and everything to do with a problem
in our GRUB configuration generator and having /gnu/store on a Btrfs
submodule.

In particular, this generated pice of GRUB configuration:

--8<---------------cut here---------------start------------->8---
if loadfont /rootfs/gnu/store/m1fx9h7gzw78k0n4da0khbga5i6k8ipk-grub-2.04/share/grub/unicode.pf2; then
  setup_gfxterm
fi
--8<---------------cut here---------------end--------------->8---

was causing the setup_gfxterm to not be called due to failing to resolve
the unicode.pf2 file when using a Btrfs submodule.

The originally attached patches still provide some >
simplification/cleanup that would make it good to merge nontheless, I
believe!
