50 * decides how to configure logical displays based on the physical display devices currently
54 * The display manager service relies on a collection of {@link DisplayAdapter} components,
55 * for discovering and configuring physical display devices attached to the system.
56 * There are separate display adapters for each manner that devices are attached:
57 * one display adapter for built-in local displays, one for simulated non-functional
61 * Display adapters are only weakly coupled to the display manager service.
62 * Display adapters communicate changes in display device state to the display manager
64 * by the display manager service. This separation of concerns is important for
66 * two classes: display adapters handle individual display devices whereas
67 * the display manager service handles the global state. Second, it eliminates
68 * the potential for deadlocks resulting from asynchronous display device discovery.
73 * Because the display manager may be accessed by multiple threads, the synchronization
