From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How to automatically assign classes in GRUB? (kbin.social)

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.

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

		initrd	/boot/initrd.img-5.15.0-91-generic
}

The linux proxy file has this inside it:
