All options are configured in the [Login] section: KillUserProcesses= Takes a boolean argument. Configures whether the processes of a user should be killed when the user completely logs out (i.e. after the user's last session ended). Defaults to no. Note that setting KillUserProcesses=1 will break tools like screen1. KillOnlyUsers= KillExcludeUsers= These settings take space-separated lists of usernames that influence the effect of KillUserProcesses=. If not empty, only processes of users listed in KillOnlyUsers= will be killed when they log out entirely. Processes of users listed in KillExcludeUsers= are excluded from being killed. KillExcludeUsers= defaults to root and takes precedence over KillOnlyUsers=, which defaults to the empty list. IdleAction= Configures the action to take when the system is idle. Takes one of ignore, poweroff, reboot, halt, kexec, suspend, hibernate, hybrid-sleep, 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. HandlePowerKey= HandleSuspendKey= HandleHibernateKey= HandleLidSwitch= HandleLidSwitchDocked= Controls whether 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, 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. 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; otherwise the HandleLidSwitch= action occurs. PowerKeyIgnoreInhibited= SuspendKeyIgnoreInhibited= HibernateKeyIgnoreInhibited= LidSwitchIgnoreInhibited= Controls whether actions triggered by the power and sleep keys and the lid switch are subject to inhibitor locks. These settings take boolean arguments. If no, the inhibitor locks taken by applications in order to block the requested operation are respected. If yes, the requested operation is executed in any case. PowerKeyIgnoreInhibited=, SuspendKeyIgnoreInhibited= and HibernateKeyIgnoreInhibited= default to no. LidSwitchIgnoreInhibited= defaults to yes. This means that 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 systemd will hold off on reacting to LID events. This is required for the system to properly detect any hotplugged devices so systemd can ignore LID events if external monitors, or docks, are connected. If set to 0, systemd will always react immediately, possibly before the kernel fully probed all hotplugged devices. This is safe, as long as you do not care for systemd to account 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. 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 are excluded from the effect of this setting. Defaults to yes. systemd1, logind.service8, loginctl1, systemd-system.conf5
