I personally prefer sudo (apt-get install sudo), put yourself into 
/etc/sudoers as:

your-user-name ALL=(ALL) ALL

That way you can launch _any_ program as root from an user X-session.
You could be more restrictive with your permissions if you don't need
more than a few commands as root.

Have fun!
