dm-tool [ OPTIONS ] COMMAND [ ARGS ]
dm-tool is a tool to communicate with the LightDM display manager.
- -h, --help
- Show help options
- --version
- Show release version
- --session-bus
- Attempt to connect to the display manager using the session bus. This is
useful if you are running a display manager in a test mode. If this option
is not present dm-tool will connect using the system bus.
- The following commands are available:
- switch-to-greeter
- Switch to the greeter suitable for logging into a new session.
- switch-to-user USERNAME [SESSION]
- Switch to a user session. If this user is already logged in then the
display manager will switch to that session, otherwise a new session is
started. If authentication is required a greeter will start to collect
this. If the session option is provided then this session type will be
used, otherwise the default for this user is used.
- switch-to-guest [SESSION]
- Switch to a guest session. If the guest session is already active the
display manager will switch to that session, otherwise the guest session
is started. If the session option is provided then this session type will
be used, otherwise the default for the guest user is used.
- lock
- Lock the current seat. This will switch to a greeter with a hint that the
screen is locked. You can return to this session by authenticating in the
greeter.
- list-seats
- List the active seats and sessions that are running.
- add-nested-seat
- Start an X server inside a session and connect it to a display
manager.
- add-local-x-seat DISPLAY_NUMBER
- Connect an existing X server to the display manager.
- add-seat TYPE [NAME=VALUE...]
- Add a dynamic seat.
- XDG_SEAT_PATH
- Used by dm-tool to determine in which display manager session it's
running. When executing dm-tool outside of a display-manager use
its list-seats command to show active sessions and set the session
to connect to with: export
XDG_SEAT_PATH=/org/freedesktop/DesktopManager/SeatX where SeatX
is one of the listed sessions.
