This theme was designed for a 1920x1080 display. Refer to the wiki to see how to customize it for a different resolution.

git clone --depth=1 https://github.com/uiriansan/LainGrubTheme && cd LainGrubTheme && ./install.sh

1. Clone this repo:

git clone --depth=1 https://github.com/uiriansan/LainGrubTheme.git
cd LainGrubTheme

2. Copy lain/ into /boot/grub/themes/:

sudo cp -rf lain /boot/grub/themes/

3. In /etc/default/grub, uncomment the line that says "GRUB_THEME" and add the path to theme.txt:

sudoedit /etc/default/grub

    # It should look like this:
    GRUB_THEME="/boot/grub/themes/lain/theme.txt"

4. Set GRUB_GFXMODE= to the correct resolution:

GRUB_GFXMODE=1920x1080

5. Optionally, make Grub remember the last option selected by modifying GRUB_DEFAULT= and GRUB_SAVEDEFAULT=:

GRUB_DEFAULT=saved
GRUB_SAVEDEFAULT=true # Make sure to uncomment this one.

There are some limitations to what a GRUB theme can do. By default, some GRUB entries have really long names and no icons (e.g. os-prober entries and Advanced options). To change this, we need to edit some GRUB scripts located in /etc/grub.d/. Run patch_entries.sh to apply some changes automatically.

Read the wiki.
