Dear Maintainer,

GRUB_GFXMODE=2560x1440 and GRUB_BACKGROUND=/usr/share/desktop-base/emerald-
theme/grub , have no effect on GRUB resolution or background image.

I updated to Debian 12 (Bookworm) grub-efi, grub-efi-amd64 and grub-efi-
amd64-bin to version 2.06-12 yesterday and found that grub-efi was updated. I
customized the "/etc/default/grub" file to get the resolution of my screen
(2560x1440) by modifying the parameter GRUB_GFXMODE=2560x1440. This action has
no effect when restarting the PC. I did an "update-grub" before the reboot.
GRUB_BACKGROUND=/usr/share/desktop-base/emerald-theme/grub does't display the
background image.

Thanks for your help.
