NAME
logind.conf, logind.conf.d - Login manager configuration files
SYNOPSIS
DESCRIPTION
These files configure various parameters of the systemd login manager, systemd-logind.service(8). See systemd.syntax(7) for a general description of the syntax.
CONFIGURATION DIRECTORIES AND PRECEDENCE
The default configuration is set during compilation, so configuration is only needed when it is necessary to deviate from those defaults. The main configuration file is loaded from one of the listed directories in order of priority, only the first file found is used: /etc/systemd/, /run/systemd/, /usr/local/lib/systemd/ [1], /usr/lib/systemd/. The vendor version of the file contains commented out entries showing the defaults as a guide to the administrator. Local overrides can also be created by creating drop-ins, as described below. The main configuration file can also be edited for this purpose (or a copy in /etc/ if it's shipped under /usr/), however using drop-ins for local configuration is recommended over modifications to the main configuration file.
In addition to the main configuration file, drop-in configuration snippets are read from /usr/lib/systemd/*.conf.d/, /usr/local/lib/systemd/*.conf.d/, and /etc/systemd/*.conf.d/. Those drop-ins have higher precedence and override the main configuration file. Files in the *.conf.d/ configuration subdirectories are sorted by their filename in lexicographic order, regardless of in which of the subdirectories they reside. When multiple files specify the same option, for options which accept just a single value, the entry in the file sorted last takes precedence, and for options which accept a list of values, entries are collected as they occur in the sorted files.
When packages need to customize the configuration, they can install drop-ins under /usr/. Files in /etc/ are reserved for the local administrator, who may use this logic to override the configuration files installed by vendor packages. Drop-ins have to be used to override package drop-ins, since the main configuration file has lower precedence. It is recommended to prefix all filenames in those subdirectories with a two-digit number and a dash, to simplify the ordering. This also defines a concept of drop-in priorities to allow OS vendors to ship drop-ins within a specific range lower than the range used by users. This should lower the risk of package drop-ins overriding accidentally drop-ins defined by users. It is recommended to use the range 10-40 for drop-ins in /usr/ and the range 60-90 for drop-ins in /etc/ and /run/, to make sure that local and transient drop-ins take priority over drop-ins shipped by the OS vendor.
To disable a configuration file supplied by the vendor, the recommended way is to place a symlink to /dev/null in the configuration directory in /etc/, with the same filename as the vendor configuration file.
OPTIONS
All options are configured in the [Login] section:
NAutoVTs=
ReserveVT=
Added in version 190.
KillUserProcesses=
In addition to session processes, user process may run under the user manager unit user@.service. Depending on the linger settings, this may allow users to run processes independent of their login sessions. See the description of enable-linger in loginctl(1).
Note that setting KillUserProcesses=yes will break tools like screen(1) and tmux(1), unless they are moved out of the session scope. See example in systemd-run(1).
KillOnlyUsers=, KillExcludeUsers=
IdleAction=
Note that this requires that user sessions correctly report the idle status to the system. The system will execute the action after all sessions report that they are idle, no idle inhibitor lock is active, and subsequently, the time configured with IdleActionSec= (see below) has expired.
Added in version 198.
IdleActionSec=
Added in version 198.
InhibitDelayMaxSec=
UserStopDelaySec=
Added in version 240.
SleepOperation=
Added in version 256.
HandlePowerKey=, HandlePowerKeyLongPress=, HandleRebootKey=, HandleRebootKeyLongPress=, HandleSuspendKey=, HandleSuspendKeyLongPress=, HandleHibernateKey=, HandleHibernateKeyLongPress=, HandleLidSwitch=, HandleLidSwitchExternalPower=, HandleLidSwitchDocked=
HandlePowerKey= defaults to "poweroff", HandleRebootKey= defaults to "reboot", HandleSuspendKey= defaults to "suspend", HandleHibernateKey= defaults to "hibernate", HandlePowerKeyLongPress= defaults to "ignore", HandleRebootKeyLongPress= defaults to "poweroff", HandleSuspendKeyLongPress= defaults to "hibernate", HandleHibernateKeyLongPress= defaults to "ignore". HandleLidSwitch= defaults to "suspend". HandleLidSwitchExternalPower= is completely ignored by default (for backwards compatibility) — an explicit value must be set before it will be used to determine behaviour. HandleLidSwitchDocked= defaults to "ignore". If the system is inserted in a docking station, or if more than one display is connected, the action specified by HandleLidSwitchDocked= occurs; if the system is on external power the action (if any) specified by HandleLidSwitchExternalPower= occurs; otherwise the HandleLidSwitch= action occurs.
A different application may disable logind's handling of system power and sleep keys and the lid switch by taking a low-level inhibitor lock ("handle-power-key", "handle-suspend-key", "handle-hibernate-key", "handle-lid-switch", "handle-reboot-key"). This is most commonly used by graphical desktop environments to take over suspend and hibernation handling, and to use their own configuration mechanisms. If a low-level inhibitor lock is taken, logind will not take any action when that key or switch is triggered and the Handle*= settings are irrelevant.
Added in version 184.
PowerKeyIgnoreInhibited=, SuspendKeyIgnoreInhibited=, HibernateKeyIgnoreInhibited=, LidSwitchIgnoreInhibited=, RebootKeyIgnoreInhibited=
These settings take boolean arguments. If "no", the inhibitor locks taken by applications are respected. If "yes", "shutdown", "reboot" "sleep", and "idle" inhibitor locks are ignored. PowerKeyIgnoreInhibited=, SuspendKeyIgnoreInhibited=, HibernateKeyIgnoreInhibited= and RebootKeyIgnoreInhibited= default to "no". LidSwitchIgnoreInhibited= defaults to "yes". This means that when systemd-logind is handling events by itself (no low level inhibitor locks are taken by another application), the lid switch does not respect suspend blockers by default, but the power and sleep keys do.
Added in version 190.
HoldoffTimeoutSec=
Added in version 220.
RuntimeDirectorySize=
Added in version 211.
RuntimeDirectoryInodesMax=
Added in version 246.
InhibitorsMax=
Added in version 230.
SessionsMax=
Added in version 230.
RemoveIPC=
Added in version 212.
StopIdleSessionSec=
Added in version 252.

- 💣💥🧨💥💥💣 Please note that those configuration files must be available at all times. If /usr/local/ is a separate partition, it may not be available during early boot, and must not be used for configuration.
