"su" to root should only be given to folks what know their way around under the hood, since root privs mean you can really mess up the system. You can set your system to be able to log into the root account from the login prompt. When logged in to your normal user account, type "sudo passwd". This will allow you to set the root password on your system, which I believe comes standard with the root account locked. You can then log in to the root account through the regular login account. Sudo is a way to give certain users some, or all, of the privileges given to the root account. Do a "man sudo" to see what can be done, privilege-wise, based on permissions set in the /etc/sudoers under the Ubuntu OS, or /etc/sudo.conf on other systems.
