I have my grub themed but one problem is that I need to rotate it by 90 degrees so that it doesn't appear certical and squashed any more on my Steam Deck.
Any help?
Solution
Edit the
/etc/default/grub
/etc/default/grub
file and add:
GRUB_GFXMODE=1280x800x32
GRUB_GFXMODE=1280x800x32
After that run the command
sudo grub2-mkconfig -o /etc/grub2.cfg
sudo grub2-mkconfig -o /etc/grub2.cfg
This is for the LCD Steam Deck, numbers may differ for OLED
