I use the latest version of Grub Customizer (3.0.2) and Ubuntu 12.04. On appearance settings I changed the background image and the font, but once I reboot the system they don't appear; there's always the default Ubuntu background image and the font seems a bit changed but not as expected.

I tried to resize and crop the image as described here: Why can't I see the image changed with GRUB Customizer? but it doesn't work in any case.

On /etc/default/grub:

# /boot/grub/grub.cfg.
