How do I change the GRUB2 Boot Loader Background Image?
 

I've started off using Linux with Ubuntu 10.10, and then I moved to Linux Mint 10 KDE, and after finding out that it didn't support my hardware, in specifically my Graphics Card, I switched back to Ubuntu 10.10, and from there I upgraded to 11.04. I hated the GUI so I switched it from Ubuntu to Ubuntu (Classic) environment. I also installed Kubuntu-Desktop too, and it looks a LOT like Mint 10 KDE, I guess it uses KDE 4.6, but... it's more stable for me. Anyway, what I mean is that, originally Ubuntu had a black background, Linux Mint 10 KDE had a pretty cool custom Mint background, Ubuntu 11.04 has a Purple Background. I looked on Youtube, I found people using customized backgrounds, but they either don't explain HOW they got it *Like for instance, someone said OpenSUSE 11 or 13 has an Icy Penguin animated background, and someone else had one that you could scroll through.* or it's too complicated or outdated. Is there a simple way to change your GRUB2 Boot Loader Background Image?

Grub Splash Image
 

Hello,

If I understand correctly you just want to add a splash image to Grub. This can be done by modifying the grub.conf file usually found in /boot/grub/grub.conf. First download the image you want to use and take note of where it is at. For example I have an image in Fedora called splash.xpm.gz located at /boot/grub/splash.xpm.gz. The following line in my grub.conf loads it:

splashimage=(hd0,0)/grub/splash.xpm.gz

Hope this helps.

Ubuntu 10.10 doesn't have a grub.conf file as it uses Grub2.

First, Install Grub2-splashimages packages with: sudo aptitude install grub2-splashimages
Make sure you get grub2-splashimages and not grub-splashimages.
Select an image you want. Go to /etc/grub.d/05_debian_theme file.
As root either: sudo gedit (to open text file and navigate to above file or; sudo nautilus and navigate to above file and open in text editor.

Change the line: WALLPAPER=/usr/share/images/desktop-base/moreblue-orbit-grub.png to whatever the path is where you have a picture,
I would suggest commenting out the above line by putting a hash mark (#) to the left and adding a new line below it.
After editing this file and saving it, in a terminal run update grub with: sudo update-grub. Should see a message indicating "Found background image", if not, it didn't work.

You can also make your own custom splash images but they have certain restrictions. Here is a little information
