customize grub in KDE Neon

0) Avoid Grub customizer: absolutely useless.

1) You can modify /etc/default/grub uncommenting GRUB_THEME="/boot/grub/themes/breeze/theme.txt"

2) Then you can modify /boot/grub/themes/breeze/theme.txt: for example you can
  • add a background: adding, in # General settings, a line such as "desktop-image: "your-image-in-the-same-folder.png" (obviously you have to put, as root, that image into the folder);
  • reducing the height for menu items, in "+ boot_menu": "item_height = 15" (not: 33)

fine tuning

a) you can change the screen resolution (in /etc/default/grub);
  • give this command "xrandr" in order to know the supported resolutions 
  • then uncomment/modify GRUB_GFXMODE="your desired resolution"
b) you can create your own pf2 font file, with grub-mkfont:
for example "sudo grub-mkfont --output=/boot/grub/fonts/DejaVuSans-10.pf2  --size=10 /usr/share/fonts/truetype/dejavu/DejaVuSans.ttf"

c) per installare nell'mbr
sudo grub-install /dev/sda
