Service Manager

This module allows you to have an overview of all plugins of the " "KDE Daemon, also referred to as KDE Services. Generally, there are two types of service:

" "
  • Services invoked at startup
  • Services called on demand
" "

The latter are only listed for convenience. The startup services can be started and stopped. " "In Administrator mode, you can also define whether services should be loaded at startup.

" "

Use this with care: some services are vital for Plasma; do not deactivate services if you" " do not know what you are doing.
