NAME
org.freedesktop.locale1 - The D-Bus interface of systemd-localed
INTRODUCTION
systemd-localed.service(8) is a system service that can be used to control the system locale and keyboard mapping from user programs. This page describes the D-Bus interface.
THE D-BUS API
The service exposes the following interfaces on the bus:
node
/org/freedesktop/locale1 {
interface org.freedesktop.locale1 {
methods:
SetLocale(in as locale,
in b interactive);
SetVConsoleKeyboard(in s keymap,
in s keymap_toggle,
in b convert,
in b interactive);
SetX11Keyboard(in s layout,
in s model,
in s variant,
in s options,
in b convert,
in b interactive);
properties:
readonly as Locale = ['...', ...];
readonly s X11Layout = '...';
readonly s X11Model = '...';
readonly s X11Variant = '...';
readonly s X11Options = '...';
readonly s VConsoleKeymap = '...';
readonly s VConsoleKeymapToggle = '...';
};
interface org.freedesktop.DBus.Peer { ... };
interface org.freedesktop.DBus.Introspectable { ... };
interface org.freedesktop.DBus.Properties { ... };
};
Methods
If you set a new system locale all old system locale
settings will be dropped and the new settings will be saved
to disk. The locale will also be passed to the system
manager, and subsequently started daemons will inherit the
new system locale. Note that already running daemons will
not learn about the new value.
The SetVConsoleKeyboard() method may be used to set the key mapping for the virtual console. Similarly, SetX11Keyboard() may be used to set the default key mapping of any X11 servers.
Note that SetVConsoleKeyboard() instantly applies the new key mapping to the console, while SetX11Keyboard() simply sets a default that may be used by later sessions.
The boolean argument convert may be set to optionally convert the console keyboard configuration to X11 keyboard mappings and vice versa. If true and SetVConsoleKeyboard() is used, the nearest X11 keyboard setting for the chosen console setting is set. If true and SetX11Keyboard() is used, the nearest console keyboard setting for the chosen X11 setting is set. Hence, it is usually sufficient to call only one of the two functions.
For graphical UIs that need to set the system keyboard mapping simply invoke SetX11Keyboard(), set convert=true and ignore SetVConsoleKeyboard().
Use the empty string for the keymap parameters you wish not to set.
The interactive boolean parameters can be used to control whether polkit [1] should interactively ask the user for authentication credentials if required.
Signals
Whenever the system locale or keymap is changed via the
daemon, PropertyChanged signals are sent out to which
clients can subscribe.
Properties
The system locale is shown in the Locale property. It
is an array containing environment-variable-assignment-like
strings. The following strings are known: LANG=,
LC_CTYPE=, LC_NUMERIC=, LC_TIME=,
LC_COLLATE=, LC_MONETARY=,
LC_MESSAGES=, LC_PAPER=, LC_NAME=,
LC_ADDRESS=, LC_TELEPHONE=,
LC_MEASUREMENT=,
LC_IDENTIFICATION=.
The X11Layout, X11Model, X11Variant, and X11Options properties show values configurable with SetX11Keyboard() described above (or SetVConsoleKeyboard() with convert=true). The VConsoleKeymap and VConsoleKeymapToggle properties show values configurable with SetVConsoleKeyboard() (or SetX11Keyboard() with convert=true).
Security
Changing the system locale or keymap using this interface is
authenticated via polkit. The polkit action for
SetLocale() is
org.freedesktop.locale1.set-locale. The polkit action
for SetX11Keyboard() and SetVConsoleKeyboard()
is org.freedesktop.locale1.set-keyboard.
EXAMPLES
Example 1. Introspect org.freedesktop.locale1 on the bus
$
gdbus introspect --system \
--dest org.freedesktop.locale1 \
--object-path /org/freedesktop/locale1
