Default GRUB splash screen Ubuntu 12.04

[Aleksej]

I tried the XFCE4 desktop manager for some reasons and decided to stick with Unity. The thing is, when I installed XFCE4 it changed the GRUB menu background from the plain purple splash screen into some spacey pic. I'd like to get the default plain purple GRUB menu. How can I do that?

You need to edit the /etc/default/grub file.

sudo gedit /etc/default/grub

And edit the line that begins:
GRUB_BACKGROUND=/
Point it to the path of the background you want.
Then run update-grub & reboot.

You can also try Grub Customizer which has a simple GUI for that. More info can be found here http://www.webupd8.org/2012/09/grub-...-released.html and here for how it works http://ubuntuforums.org/showthread.php?p=10340183. Hope this will help, the first suggestion though by @cottfcfan is better if you are comfortable with the Command Line Interface and editing configuration files.

or you might have to add the line as cott mentioned

also add "" here is an example form my grub

GRUB_BACKGROUND="/home/ray/121143.jpg"

also i put the .jpg i want to use in my home folder first.
