logind.conf - Login manager configuration files
This file configures various parameters of elogind.
All login options are configured in the "[Login]" section, system sleep options are configured in the "[Sleep]" section. [Login] section: KillUserProcesses= Takes a boolean argument. Configures whether the processes of a user should be killed when the user logs out. If true, the processes listed in their session cgroup will be terminated. If false, the session cgroup is ignored but see the options KillOnlyUsers= and KillExcludeUsers= below. Note that setting KillUserProcesses=yes will break tools like screen(1) and tmux(1), unless they are moved out of the session scope. KillOnlyUsers=, KillExcludeUsers= These settings take space-separated lists of usernames that override the KillUserProcesses= setting. A user name may be added to KillExcludeUsers= to exclude the processes in the session scopes of that user from being killed even if KillUserProcesses=yes is set. If KillExcludeUsers= is not set, the "root" user is excluded by default. KillExcludeUsers= may be set to an empty value to override this default. If a user is not excluded, KillOnlyUsers= is checked next. If this setting is specified, only the session scopes of those users will be killed. Otherwise, users are subject to the KillUserProcesses=yes setting. IdleAction= Configures the action to take when the system is idle. Takes one of "ignore", "poweroff", "reboot", "halt", "kexec", "suspend", "hibernate", "hybrid-sleep", "suspend-then-hibernate", and "lock". Defaults to "ignore". 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. IdleActionSec= Configures the delay after which the action configured in IdleAction= (see above) is taken after the system is idle. InhibitDelayMaxSec= Specifies the maximum time a system shutdown or sleep request is delayed due to an inhibitor lock of type "delay" being active before the inhibitor is ignored and the operation executes anyway. Defaults to 5. UserStopDelaySec= Specifies how long to keep the user record around for a user after they logged out fully. If set to zero, the user is terminated immediately when the last session of the user has ended. Defaults to 10s. HandlePowerKey=, HandleSuspendKey=, HandleHibernateKey=, HandleLidSwitch=, HandleLidSwitchExternalPower=, HandleLidSwitchDocked= Controls how logind shall handle the system power and sleep keys and the lid switch to trigger actions such as system power-off or suspend. Can be one of "ignore", "poweroff", "reboot", "halt", "kexec", "suspend", "hibernate", "hybrid-sleep", "suspend-then-hibernate", and "lock". If "ignore", logind will never handle these keys. If "lock", all running sessions will be screen-locked; otherwise, the specified action will be taken in the respective event. Only input devices with the "power-switch" udev tag will be watched for key/lid switch events. HandlePowerKey= defaults to "poweroff". HandleSuspendKey= and HandleLidSwitch= default 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". HandleHibernateKey= defaults to "hibernate". 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"). 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. PowerKeyIgnoreInhibited=, SuspendKeyIgnoreInhibited=, HibernateKeyIgnoreInhibited=, LidSwitchIgnoreInhibited= Controls whether actions that elogind takes when the power and sleep keys and the lid switch are triggered are subject to high-level inhibitor locks ("shutdown", "sleep", "idle"). Low level inhibitor locks ("handle-power-key", "handle-suspend-key", "handle-hibernate-key", "handle-lid-switch"), are always honored, irrespective of this setting. These settings take boolean arguments. If "no", the inhibitor locks taken by applications are respected. If "yes", "shutdown", "sleep", and "idle" inhibitor locks are ignored. PowerKeyIgnoreInhibited=, SuspendKeyIgnoreInhibited=, and HibernateKeyIgnoreInhibited= default to "no". LidSwitchIgnoreInhibited= defaults to "yes". This means that when elogind 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. HoldoffTimeoutSec= Specifies the timeout after system startup or system resume in which elogind will hold off on reacting to lid events. This is required for the system to properly detect any hotplugged devices so lid events can be ignored if external monitors or docks are connected. If set to 0, elogind will always react immediately, possibly before the kernel fully probed all hotplugged devices. This is safe, as long as you do not care for devices that have been plugged or unplugged while the system was off. Defaults to 30s. RuntimeDirectorySize= Sets the size limit on the $XDG_RUNTIME_DIR runtime directory for each user who logs in. Takes a size in bytes, optionally suffixed with the usual K, G, M, and T suffixes, to the base 1024 (IEC). Alternatively, a numerical percentage suffixed by "%" may be specified, which sets the size limit relative to the amount of physical RAM. Defaults to 10%. Note that this size is a safety limit only. As each runtime directory is a tmpfs file system, it will only consume as much memory as is needed. InhibitorsMax= Controls the maximum number of concurrent inhibitors to permit. Defaults to 8192 (8K). SessionsMax= Controls the maximum number of concurrent user sessions to manage. Defaults to 8192 (8K). Depending on how the pam_elogind.so module is included in the PAM stack configuration, further login sessions will either be refused, or permitted but not tracked by elogind. RemoveIPC= Controls whether System V and POSIX IPC objects belonging to the user shall be removed when the user fully logs out. Takes a boolean argument. If enabled, the user may not consume IPC resources after the last of the user's sessions terminated. This covers System V semaphores, shared memory and message queues, as well as POSIX shared memory and message queues. Note that IPC objects of the root user and other system users are excluded from the effect of this setting. Defaults to "yes". [Sleep] section: elogind supports three general power-saving modes: suspend a low-power state where execution of the OS is paused, and complete power loss might result in lost data, and which is fast to enter and exit. This corresponds to suspend, standby, or freeze states as understood by the kernel. hibernate a low-power state where execution of the OS is paused, and complete power loss does not result in lost data, and which might be slow to enter and exit. This corresponds to the hibernation as understood by the kernel. hybrid-sleep a low-power state where execution of the OS is paused, which might be slow to enter, and on complete power loss does not result in lost data but might be slower to exit in that case. This mode is called suspend-to-both by the kernel. suspend-then-hibernate enter suspend state with a timeout that will activate hibernate later. SuspendMode=, HibernateMode=, HybridSleepMode= The string to be written to /sys/power/disk by elogind. More than one value can be specified by separating multiple values with whitespace. They will be tried in turn, until one is written without error. If neither succeeds, the operation will be aborted. SuspendState=, HibernateState=, HybridSleepState= The string to be written to /sys/power/state by elogind. More than one value can be specified by separating multiple values with whitespace. They will be tried in turn, until one is written without error. If neither succeeds, the operation will be aborted.
