KDE Plasma Workspaces provide a graphical interface and lots of eye candy for the desktop Linux experience. Many would argue that it is equal to or even better at this than Microsoft Windows and Mac OS X. KDE, however, is not only a graphical frontend for Linux. It comes with a set of applications and also with a set of system administration tools that can help power users take control of their desktops or laptops without dropping to the command line.
KDE administration tools are primarily located in System Settings. Start system settings by clicking on the kickoff (K) launcher button and selecting “System Settings” or by pressing Alt+F2 and typing “System Settings”. If, for some reason, you cannot find it, the command path is /usr/bin/systemsettings.
