logind.conf
Login manager configuration file
logind.conf
Description
This files configures various parameters of the systemd login manager systemd-logind.service8.
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
screen1.
Note that KillUserProcesses=1
is a weaker version of
kill-session-processes=1 which may
be configured per-service for
pam_systemd8. 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.
