How to change the purple background color in grub?
The default background color for GRUB2 in ubuntu11.10 is a dark-magenta-purple. How to change this color to black so that I don't have a purple splash on boot. (I want to keep everything black and hidden).
The background color is already set to black:
gksudo gedit /etc/grub.d/05_debian_theme
COLOR_NORMAL="white/black"
This is called the 'normal background' color in GRUB. The word 'black' in this position means 'transparent' to GRUB2
