If you have a multi-boot system, the first screen you get on booting allows you to choose which OS you will boot into.

By default this screen is a plain dull color. But it is possible to jazz it up with a simple background picture as the screenshot below shows:


There are certain requirements on the background picture - it has to be displayed before an operating system is running, so it cannot be that fancy or large. It must have no more than 14 colors, and should be 640x480 in size. The picture should be simple so it does not obscure the boot choices, and it should have a contrasting background that shows up the white text.

You can download the image_magick utility from CNR (just get it from aisle pvdl-aisle for simplicity).
Then choose the image file (jpg, png, gif etc) that you want to use as the background (perhaps searching at google images), download it to your system and call it, e.g. "myfile.jpg".

Bring up a command window with Launch, Run command, "type "konsole" in the text field, then issue these commands in the command window that appears:

convert myfile.jpg -colors 14 -resize 640x480 myfile.xpm

gzip myfile.xpm

mv myfile.xpm.gz /boot/grub

The final step is to edit the GRUB bootloader's configuration file to tell it to use this background image. Make a backup copy of the file /boot/grub/menu.lst, then edit it and find the existing line:
splashimage=/boot/grub/bootsplash.xpm.gz
and change it to refer to your file:

splashimage=/boot/grub/myfile.xpm.gz

You will see the image on your next reboot.
You can search the internet and create your own image, or you can download and use the "tux swats windows moth" image shown above from http://afu.com/linux/tuxswat.xpm.gz

If you tried this tip and created your own background image, please share your image here in a follow-up post. (You can get an image to appear here by putting it on an image server, using the "Img" button when you post, then entering the URL of your picture on the image server. I like the free image server http://tinypic.com/ because they run Linux).

Peter

Hi Peter
I have done as you instructed but how do I do the following as I cannot find any menu in the program apart from the right click which doesn't seem to have any way of inserting the commands.


Quote:
issue these commands:

convert myfile.jpg -colors 14 -resize 640x480 myfile.xpm

gzip myfile.xpm

mv myfile.xpm.gz /boot/grub


I would be glad of any help. Can't wait for the book hoping it will explain some of the misterys Smile Smile Wink

Did you ever get a reply about where to enter the commands in the program from CNR??

I sent the reply by PM on the same day it was asked. I was trying to reserve this forum for tips, rather than discussion of same. Also have updated the tip to explicitly spell out how to start a command window.

Thanks for the tip, Peter. Here's my bootsplash screen. It's a keyboard with the Windows key replaced by the Linspire "L".
