In regular Ubuntu (Unity/Gnome), I use
gksudo to run GUI programs with root privileges. I'm trying out Kubuntu (or KDE) now -- what do I use?
The Kubuntu/KDE equivalent of gksudo is
kdesudo. You can use this in the terminal or via the graphical command box on the top of the screen (Alt-F2).
When you do this, or otherwise launch an application which requires root privileges, you will get a kdesudo popup like this:
Note: If you are not getting this box with GUI applications, it may indicate a problem with the way the KDE desktop environment was installed. Please try reinstalling
kubuntu-desktopif you are not using Kubuntu.
