Yes I do, 1070, I've posted more details of my system in an answer and in the main thread. But I use the proprietary drivers not nouveau

The desktop is Cinnamon, I did include it in the original post too, maybe I should make it clearer.

Laptop is an MSI GS65-Stealth-Thin-8RF

The linux proxy file has this inside it:

#!/bin/sh

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
	savedefault
		load_video
		gfxmode $linux_gfx_mode
		insmod gzio
		if [ x$grub_platform = xxen ]; then insmod xzio; insmod lzopio; fi
		insmod part_gpt
		insmod ext2
		search --no-floppy --fs-uuid --set=root 9e121508-86c8-407a-803d-9521d13f0be9
		echo	'Loading Linux 5.15.0-91-generic ...'
		linux	/boot/vmlinuz-5.15.0-91-generic root=UUID=9e121508-86c8-407a-803d-9521d13f0be9 ro  
		echo	'Loading initial ramdisk ...'
		initrd	/boot/initrd.img-5.15.0-91-generic
}

...more entries here

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)

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

I'm not managing to get it to work on the submenu entry, only on the efi one. Don't know why

daje, grazie! (thanks!)

should I just add the class parameter in these files where it is usually supposed to be, and the files even on updates will not be changed and this will work?

Here it is: https://textdoc.co/qNyF4iIgsaTo5cZX

It seems too long to copy paste here

I use a homemade solution, it doesn't autofill, but I trust it better and I'm proud of it
