etcsystemdlogindconf

etcsystemdlogindconf refers to the configuration file /etc/systemd/logind.conf, which is used by systemd-logind—the login and session manager in many Linux distributions. This file controls how systemd-logind handles user logins, seats and sessions, as well as certain power-management behaviors such as actions taken when the lid is closed, when the power key is pressed, and how idle timeouts are handled.

The file is located at /etc/systemd/logind.conf and uses a simple key=value syntax. Settings are typically placed under a [Login] section, and lines beginning with a hash sign are treated as comments. The behavior defined in this file can be extended or overridden by drop-in configuration fragments placed in /etc/systemd/logind.conf.d/ or by distribution-provided defaults in other system directories, allowing local customization without modifying the packaged file directly.

Common options control a range of actions and policies. Examples include handling of hardware events such as the power key or lid switch (for instance, keys like HandlePowerKey, HandleSuspendKey, HandleLidSwitch, and HandleLidSwitchDocked), and idle management settings (IdleAction and IdleActionSec) that determine what happens after a period of inactivity. There are also controls related to process cleanup on logout (such as KillUserProcesses, KillOnlyUsers, and KillExcludeUsers) and delays related to inhibitors (such as InhibitDelayMaxSec). The exact set of options and their allowed values are described in the systemd-logind.conf(5) manual page.

To apply changes, restart the systemd-logind service (for example, systemctl restart systemd-logind). In some cases, a daemon reload may be advisable, and note that changes affect new sessions and may not impact already active ones. See also the systemd-logind.conf manual for detailed guidance.
