Old theme absent in grub2 after update

General system Multimedia
1

I update infrequently (~ 1 every 2-3 weeks). The update went fine today, but when I rebooted, my EndeavourOS theme was gone from Grub.

After much experimenting with /etc/default/grub, downgrading and googling, I was able to restore the theme when I added the module

efi_uga

to GRUB_PRELOAD_MODULES=“”

It worked for me, but I make no general promises! This appears to be a recent issue with grub2. There are reports of theme and background issues in other distros. I found the module kludge at the Mint forum.

My preload now looks like this:

GRUB_PRELOAD_MODULES="part_gpt part_msdos gfxmenu png efi_uga"
/etc/default/grub 
# GRUB boot loader configuration

GRUB_DEFAULT=saved
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="EndeavourOS"
GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet"
GRUB_CMDLINE_LINUX=""

# Preload both GPT and MBR modules so that they are not missed
GRUB_PRELOAD_MODULES="part_gpt part_msdos gfxmenu png efi_uga"
