previously I wrote the second one, may be you tried that one which I later edited and added sudo. Sudo is required to be able to edit and save the preference file. If second one was what you tried worked then get rootsh from repository. It should work then. If first one worked from x-term then I have no idea what went wrong, basically clicking on menu and typing first command should do the same thing.
