Custom grub theme for lubuntu. Inspired from breeze theme.
The file src/boot/grub/themes/lubuntu-grub-theme/icons/lubuntu.png has dimensions of 512x512 px.
I don't see, where this file is used. And isn't it a bit oversized, if it is used in the Grub theme?
In my opinion, /etc/default/grub.d/lubuntu-theme.cfg would be the better and clearer name for the configuration file.
Please remove code, that is commented out.
