When you say "login as administrator

You need to understand that Ubuntu uses sudo
for tasks that require administrator privileges. Enabling the root account in Ubuntu is not
I have seen a great many people here on LQ and on ubuntuforums.org
who manage to get themselves into all kinds of trouble by enabling the root account on Ubuntu.
Also, you should never login as root (or administrator). Logging in and running the system as root is asking for trouble.
I have been using Ubuntu since the inaugural version 4.10. I have never found any need to enable the root account on Ubuntu.
If you have been logging in and running the system as root, then the most likely explanation here is that you managed to change the permissions on some important system files because you were using the root account.
It can be very difficult to find exactly where the problem lies if this is the cause of your trouble.
Are you able to login using your normal user account? Are you able to perform administrator tasks using sudo??
If so, then continue to use the system as recommended and do not enable then root account again.
