When it asks for the root password, I notice I keep those root powers and access for the rest of my session. Is there a way to log out of root?
If you log in as root from a terminal session, then just enter “exit” without the quotes to become a normal user again. When you run an application as root from the gui (KDE or GNOME), you must close that program to stop being root (exp: kdesu kwrite, assume root running kwrite. Must exit kwrite to stop being root).
