If your X server already supports compositing, switching it on is as easy as opening System Settings, opening the Worskpace Appearance and Behaviour module, choosing Desktop Effects and enabling the checkbox Enable desktop effects at startup. More advanced compositing settings (such as Use VSync, Scale method, Compositing type) are available through the Advanced dialog. Customising the behaviour of the KWin effects means opening the All effects tab, and choosing the plugins you want to use. Please note that only a subset of the plugins works with XRender-based compositing. For the full experience, you need to use OpenGL mode.
