I'm running Kubuntu and one of the features I've never found a use for is Activities. For the uninitiated, it lets you set up your desktops and applications based on the activity you're doing... Pretty smart stuff if you need or want it, but I don't.

It currently litters several context menus in and around the desktop and while that isn't causing me physical harm, I'd prefer it if KDE just pretended Activities never existed.

Is there a way to disable Activities completely for a user (or globally)?
