Kubuntu Linux runs the the desktop as a regular user account, and so all programs launched are launched in the context of a normal user account.

To run a command-line program with superuser(root) priviledges, you normally will preceed the command with “sudo”, as shown in this example:

sudo gedit filename.txt

You can easily and quickly run any program as root by preceeding the command with the “gksu” command. For instance, let’s launch xterm as root by hitting Alt+F2 to bring up the quick run dialog:

We’ll first see the password dialog shown above, enter your password… and there we go - we now have a terminal running as root:

Easy stuff!
