Some people find the default root access (sudo) in Ubuntu/Kubuntu distributions little frustrating and would rather prefer to have it the old way, that is by typing su followed by password and then performing the tasks as root.
Here is how it is done:
me@a64untu:~$ sudo passwd root
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
me@a64untu:~$ sudo -i
Now, as root, using your favorite editor, edit /etc/sudoers to enable a root account.
