说明

dm-tool is a command-line utility for interacting with the LightDM display manager. It provides session management capabilities including locking the current session, switching between users, and displaying the greeter (login screen) without logging out. The tool enables multi-user workflows by allowing quick user switching while preserving all open sessions. It can also manage display seats, which are independent workstations consisting of a display, keyboard, and mouse. dm-tool communicates with LightDM via D-Bus, sending commands that control the display manager's behavior. This makes it useful for scripting and custom session management workflows on systems using LightDM.
