Lock your KDE screen from the command line

January 29th, 2009 by T4L

Did you know you can lock your current KDE screen by using the command line? For the 3.x series use

dcop kdesktop KScreensaverIface lock

and for KDE 4.x try

qdbus org.freedesktop.ScreenSaver /ScreenSaver Lock

With the help of these you should be able to craft a simple shell script that will lock your screen at given actions. For example, you can leave your screen unlocked and make the PC activate the commands above when it detects mouse movement or when a certain application is launched.
