Hi, I’m not the most expert user, but I’ve been messing with my latest linux install for a few months. I costumized the look of the GRUB, but whenever the kernel gets updated and the grub.cfg gets regenerated, the classes of two entries do not generate (efi and submenu), leaving the entries with no icons (which are determined by the class of the entry).

How do I make it so they automatically generate, instead of me modifing the .cfg everytime the kernel is updated?

I’m on linux mint, 21.2 Cinnamon.

    These files are not changed on updates. grub.cfg will be changed, but it will contain what these scripts write into it, so if you add classes to them, they will appear in new grub.cfg.

    To test that everything works as expected, backup your current grub.cfg and run sudo update-grub.

          there were 2 scripts that semeed related to that: 10_linux_proxy and 35_linux_proxy.
          There is a folder called proxified scripts, and inside it there are two files: linux and os-prober

          Here is the text in the linux file: https://textdoc.co/V3atnuEvcG4QlPUp

          I’m not sure what to do with it

            You need to add class to this line:

            echo "submenu '$(gettext_printf "Advanced options for %s" "${OS}" | grub_quote)' $menuentry_id_option 'gnulinux-advanced-$boot_device_id' {"

            Insert ${CLASS} before $menuentry_id_option:

            echo "submenu '$(gettext_printf "Advanced options for %s" "${OS}" | grub_quote)' ${CLASS} $menuentry_id_option 'gnulinux-advanced-$boot_device_id' {"

              it’s not working, also I don’t know why when I went in that line I have a \ now, that wasn’t there before apparently, before $menuentry:

              echo "submenu '$(gettext_printf "Advanced options for %s" "${OS}" | grub_quote)' \$menuentry_id_option 'gnulinux-advanced-$boot_device_id' {"

              (I’ve tried adding it also in front of ${CLASS}, leaving it only were it is, and removing it from both)

              What generates is this, so I think it’s from the linux proxy 35:

              ### BEGIN /etc/grub.d/35_linux_proxy ###
submenu "Advanced Options"{
menuentry "Ubuntu, with Linux 5.15.0-91-generic" --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-5.15.0-91-generic-advanced-9e121508-86c8-407a-803d-9521d13f0be9' {
		recordfail

}

                The linux proxy file has this inside it:
