Have a quick look at this thread:
How to solve kdesu´s prompt for a password in openSUSE 11.0 - openSUSE Forums
...then the easiest way is to follow the instructions here:
Default kdesu to use sudo and not su | Ben Kevan's Blog
It depends on which version of KDE you are using (if you are using KDE of course!),
It makes the whole desktop much smoother, it won't even prompt you for a password when your account is admin capable, and is better than running as root as some software actually refuses to run, and you might get the annoying "running as superuser" message on each login.
I understand the nuisance factor, especially if you are a little older and or have memory problems or sight problems, and that will fix it.
Have fun
