Описание (Description)
systemd-logind
is a system service that manages user logins. It
is responsible for:
• Keeping track of users and sessions, their processes and
their idle state. This is implemented by allocating a systemd
slice unit for each user below user.slice, and a scope unit
below it for each concurrent session of a user. Also, a
per-user service manager is started as system service
instance of user@.service for each logged in user.
• Generating and managing session IDs. If auditing is available
and an audit session ID is already set for a session, then
this ID is reused as the session ID. Otherwise, an
independent session counter is used.
• Providing polkit
[1]-based access for users for operations
such as system shutdown or sleep
• Implementing a shutdown/sleep inhibition logic for
applications
• Handling of power/sleep hardware keys
• Multi-seat management
• Session switch management
• Device access management for users
• Automatic spawning of text logins (gettys) on virtual console
activation and user runtime directory management
User sessions are registered with logind via the pam_systemd(8)
PAM module.
See logind.conf(5) for information about the configuration of
this service.
See sd-login(3) for information about the basic concepts of
logind such as users, sessions and seats.
See org.freedesktop.login1(5) and org.freedesktop.LogControl1(5)
for information about the D-Bus APIs systemd-logind provides.
For more information on the inhibition logic see the Inhibitor
