I've got a Debian 10 box which has no desktop environment currently installed. I'd like to put vanilla GNOME on it, but I've noticed that when I install the gnome package via apt, the desktop-base package changes the theme of the GRUB screen on boot.

Without desktop-base installed, the GRUB screen is blue and plain, and with it installed, it is gray with the Debian logo everywhere. Does anyone know how to revert this once desktop-base is installed?

This is handled by /etc/grub.d/05_debian_theme, which reads /usr/share/desktop-base/grub_background.sh if desktop-base is installed:

if [ -f "/usr/share/desktop-base/grub_background.sh" ]; then
        . "/usr/share/desktop-base/grub_background.sh"

If you delete those three lines from /etc/grub.d/05_debian_theme, and run update-grub (as root), you’ll get the plain blue screen back.
