GRUB (Grand Unified Boot-loader ) is the default boot-loader of almost all Linux Distros except some like Slackware which prefer LILO over GRUB. It is a Boot-loader developed by the GNU project.
GRUB is the most powerful and flexible boot-loader designed ever.
This article throws light on customising your default lousy GRUB background with a wallpaper of your choice.
The image format required for GRUB Background is .xpm.gz
To convert your wallpapers into .xpm.gz format you either need GIMP (GNU Image Manipulator) or Image Magic.
- Open your image in either of the Graphical tools mentioned above .
- The image resolution should be reduced to 640x480 by scaling option available in GIMP.
- Reduce the colors of the image from 256 to 14 using GIMP tools.
- Save the file as .xpm
- Exit the Graphical tools.
- To gzip the image
$ gzip splash.xpm
At terminal type the following command :
$ convert splash.png -resize 640x480! -colors 14 -depth 8 splash.xpm.gz
Source file is splash.png
Move the image to /boot/grub using command :
$ mv splash.xpm.gz /boot/grub
Make a backup of the default splash.xpm.gz and Overwrite with your new splash Background image.
Restart your computer and here you are with your own GRUB background.
