“Let me point out here that to gain a more unified experience
from boot until your desktop is loaded, you can also modify the
GRUB screen and the OS Loading screen (many distros have started
using Plymouth for this), but that depends on your version of GRUB
and the Distribution you use. You will be better off asking for
help on your distros’ forums. Below I will only present some of the
changes that can be done to KDE 4.4.”
