is there a way to (as a non-superuser) become a temporary superuser? what I mean by this is: is there a way to change the setup so I can perform all actions (in a graphical interface even) as tho I were the root user?
I know how to open a terminal and use su to get the permission to do whatever in the terminal, but if I want to be able to do anything
outside the terminal for only a short period, how would I do that?
