su command won't work, but sudo will???!!!???

[Vikeyev]

Hello,

I was attempting to install the fglrx driver on my new ubuntu insallation, following a guide I found from google. At one point it says I need to login as super user, so I tried and no matter how many times I try it just keeps saying authentication failed. I even tried typing in my password with 1 finger, multiple times, every single time, authentication failed. So I decided to try the sudo command with fdisk -l, worked flawlessly. Tried the su command again, authentication failed, I have no idea what in heck is causing this but it just won't stop happening.

Any help you can offer would be greatly appreciated.

OH almost forgot to add my specs:

The root user account is disabled by default in Ubuntu. Check this article for more info on using sudo and su under Ubuntu:
