The kbdd daemon monitors keyboard and mouse activity. The kbdd daemon is spawned by the master daemon if the X_RUNS_HERE keyword in the configuration file is set to true.
The kbdd daemon notifies the startd daemon when it detects keyboard or mouse activity; however, kbdd is not interrupt driven. It sleeps for the number of seconds defined by the POLLING_FREQUENCY keyword in the LoadLeveler configuration file, and then determines if X events, in the form of mouse or keyboard activity, have occurred. For more information on the configuration file, see Chapter 5, Administering and Configuring LoadLeveler.
