ATTENTION: Word of caution before reading forward. It is potentially dangerous
logging in as root.

We all love utilising sudo / gksu for superuser powers, but it is possible to
permanently enable to root account so you can log into it.

Activate root user by assigning a password. Type the following:
$ sudo passwd root

Than type a new password that you will use to log into root, keep it long and
funky.

In the future you can switch to root user at the command prompt by typing su.
Click System | Administration | Login Window, than click Security tab and check
Allow Local System Administrator Login. Close program, log out and log back in
as 'root'.

AGAIN please note, running GUI as root is VERY DANGEROUS, but you cares, it is
your computer!
