logind.conf, logind.conf.d — Login manager configuration files
/etc/systemd/logind.conf
/etc/systemd/logind.conf.d/*.conf
/run/systemd/logind.conf.d/*.conf
/usr/lib/systemd/logind.conf.d/*.conf
These files configure various parameters of the systemd login manager, logind.service(8).
Default configuration is defined during compilation, so a
configuration file is only needed when it is necessary to deviate
from those defaults. By default the configuration file in
/etc/systemd/
contains commented out entries
showing the defaults as a guide to the administrator. This file
can be edited to create local overrides.
When packages need to customize the configuration, they can
install configuration snippets in
/usr/lib/systemd/*.conf.d/
. Files in
/etc/
are reserved for the local
administrator, who may use this logic to override the
configuration files installed by vendor packages. The main
configuration file is read before any of the configuration
directories, and has the lowest precedence; entries in a file in
any configuration directory override entries in the single
configuration file. Files in the
*.conf.d/
configuration subdirectories
are sorted by their filename in lexicographic order, regardless of
which of the subdirectories they reside in. If multiple files
specify the same option, the entry in the file with the
lexicographically latest name takes precedence. It is recommended
to prefix all filenames in those subdirectories with a two-digit
number and a dash, to simplify the ordering of the files.
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.
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
screen(1).
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
".
