I’m using KDE4. How do I automatically start an application after KDE start up?
To automatically start an application after KDE start up navigate to:
KDE->Computer->System Settings->System Administration Section->Startup and Shutdown
In this window click on “Add program” button. Select your desired application from a menu or enter a full path to an executable binary. This will instruct KDE to start an application after it finished its boot.
