A Grub GFXmenu theme for small display (like my EEE-PC) based on Standby by Llewelyn Trahaearn with resources by vinceliuice.
If you want to customize your Grub with a nice dark theme that fits with old laptops with low resolution (800x600 or more) then this one is for you.
The design is inspired by Linux Mint (a good choice) but can be used on any Linux Debian derivations.

The archive contains only the theme's resources: there are no installation or configuration tools. Installing the theme and configuring GRUB to use it requires superuser privileges.

1. Extract the archive in the directory of your choice. (here /tmp)
cd /tmp
tar xvf Urko_Mint_Dark.tar.gz
2. Install in the right directory. GRUB's themes are commonly located at /boot/grub/themes/
sudo mv Urko_Dark/ /boot/grub/themes/
3. Modify GRUB_THEME in GRUB's default file at /etc/default/grub so it points to the recently extracted theme. [grub_theme="/boot/grub/themes/Urko_Dark/theme.txt"]
4. Execute grub-mkconfig according to local documentation in order to regenerate GRUB's config file with the new theme. Generally: grub-mkconfig -o /boot/grub/grub.cfg
Rem: Steps 3 and 4 can also be managed by my favorite Grub tool : GrubCustomizer (available in Lauchpad : https://launchpad.net/grub-customizer
It is also possible to modify GRUB's config file manually with a text editor but I strongly discourage you to do so if you've never done this before.
5. Reboot and enjoy!
