blueproximity KDE

Not sure why:

rfkill unblock bluetooth

Configure:

• Lock command:

  qdbus org.kde.screensaver /ScreenSaver Lock

• Unlock command:

  qdbus | grep kscreenlocker_greet | xargs -I {} qdbus {} /MainApplication quit

• Proximity command:

  qdbus org.freedesktop.ScreenSaver /ScreenSaver SimulateUserActivity
