Add an "enableCompositing" flag to the sessionsettings.conf file which determines if the compositor (compton, xcompmgr) is supposed to be started or not.

NOTE: This is a hidden option (not available in lumina-config). To disable the compositor the user will need to edit ~/.config/lumina-desktop/sessionsettings.conf by hand and add the following line:
enableCompositing=false

Then restart Lumina for the changes to take effect.
