`/etc/systemd/logind.conf`

## Description

This files configures various parameters of the systemd login manager systemd-logind.service 8.

## Options

All options are configured in the `[Login]` section:

`NAutoVTs=`

  Takes a positive integer. How many virtual terminals to allocate by default and when switched to autospawn `autovt` services on (if they are otherwise unused). These services are instantiated from a template of `autovt@.service` with the virtual terminal TTY name, e.g. `autovt@tty4.service`. By default `autovt@.service` is linked to `getty@.service`, i.e. login prompts are started dynamically as the user switches to unused virtual terminals, and this parameter hence controls how many gettys are available on the virtual terminals. Defaults to 6. When set to 0, automatic spawning of `autovt` services is disabled.

`KillUserProcesses=`

  Takes a boolean argument. Configures whether the processes of a user should be killed when she or he completely logs out (i.e. after her/his last session ended). Defaults to `no`.

`KillOnlyUsers=`
`KillExcludeUsers=`

  These settings take space separated lists of user names 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.

`Controllers=`
`ResetControllers=`

  These settings control the default control group hierarchies users logging are added to. When logging in users will get private control groups in all hierarchies listed in `Controllers=` and be reset to the root control group in all hierarchies listed in `ResetControllers=`. `Controllers=` defaults to the empty list, `ResetControllers=` defaults to `cpu`.

`InhibitDelayMaxSec=`

  Specifies the maximum time a system shutdown or sleep request is delayed due to an inhibitor lock of type `delay` being taken before it is ignored and the operation executed anyway. Defaults to 5s.

`HandlePowerKey=`
`HandleSleepKey=`
`HandleLidSwitch=`

  Controls whether logind shall handle the system power and sleep keys and the lid switch to trigger system power-off or suspend. Can be one of `off`, `no-session`, `tty-session`, `any-session` and `always`. If `off` logind will never handle these keys. If `no-session` logind will handle these keys when no user is logged in and no inhibitor lock is taken, and trigger a warnig beep otherwise. If set to `tty-session` logind will handle these keys if no inhibitor lock is taken, and either no user is logged in or the foreground session is a text login and the only one existing. If `any-session` is set logind will handle these keys if no inhibitor lock is taken, and either no user is logged in or the foreground session is the only one existing (regardless whether graphical or text). If set to `always` logind will handle these keys in any case, even if one or more users are logged in or an inhibitor lock is taken. Only input devices with the `power-switch` udev tag will be watched for key events. `HandlePowerKey=` defaults to `no-session`. `HandleSleepKey=` defaults to `tty-session`, `HandleLidSwitch=` defaults to `off`.

Note that setting `KillUserProcesses=1` will break tools like screen 1.

Note that `KillUserProcesses=1` is a weaker version of `kill-session-processes=1` which may be configured per-service for pam_systemd 8. The latter kills processes of a session as soon as it ends, the former kills processes as soon as the last session of the user ends.
