"If you have noticed, Ubuntu Karmic comes with a new xsplash
that allows you to set custom wallpaper as the background. Not only
is it more visually appealing, it is also much easier to customize
than the previous usplash. In this article, we are going to do some
thing more interesting – change the bootsplash and login
screen concurrently when you change your desktop wallpaper.
"Note: this is currently only possible with Ubuntu Karmic 9.10
or distro with xsplash installed.
"Installation
"First, install the dependencies.
sudo apt-get install imagemagick
"Download the wallpaper_daemon.py script from
Gnome-Look.org."
