EffectsHandlerImpl starts to monitor DBus for the screen being locked and provides this information to the Effect system by allowing them to ask whether the screen is currently locked and by emitting a signal when the screen gets locked/unlocked. This information is needed to ensure that no private data is shown on the screen. The following effects are adjusted: * taskbar thumbnails * thumbnail aside * mouse mark * screen shot BUG: 255712 FIXED-IN: 4.11 REVIEW: 108670
