I am relatively new to Linux and have installed VirtualBox with Xubuntu on my computer; however the screen resolution is low and stays that way. I found that installing Guest Additions should solve it. But in order to do that, I have to run the installation as root.

How do I run the installation as root?

whenever you type 'sudo', without quotes, before a command, you run it as root.

e.g. sudo vi /var/www/html/index.php this command will run the vi-editor as root and open the index.php file from your local web server.

When issuing the sudo command, you will be asked to enter your password, and you will be granted root access for the given command if you are allowed to run sudo!

If you don't belong to the sudoers or wheel group, you can still gain root access by changing your user account on the command line. You use the command 'su'. You will be asked for the root password however, so you should know it.
