I cannotn seem to do things as root. Whenever I am asked to enter authentication as root, I press enter, bacause there is no password set correct?
You will have to set a root password if you need. Most root things you can do using the "Root Terminal" instead of the "LXTerminal". Using the "Root Terminal" you can act as root but does not need to enter a password. To change the root PW enter "passwd" in the "Root Terminal" and enter your new PW twice.
