Libnotify
Libnotify は GTK+ や Qt アプリケーションのサポートを提供する Desktop Notifications Specification の実装で特定のデスクトップに依存していません: Evolution や Pidgin など多数のオープンソースアプリによって使用されています。Libnotify は公式リポジトリにある libnotify パッケージでインストールすることが可能です。
libnotify を使うには、通知サーバーをインストールする必要があります。
通知サーバー
ビルトイン
以下のデスクトップ環境では通知を表示するためにそれぞれ独自の実装を使っており、置き換えることができません。通知サーバーはログイン時に自動で起動し DBus によってアプリケーションからの通知を受け取ります。
- Cinnamon は通知サーバーを備えており、通知は画面の右上に表示されます。
- Enlightenment は Notification 拡張を通して通知サーバーを提供しています。通知オプションは設定が可能です。
- GNOME は通知サーバーを備えており、通知は画面の上部に表示されます。
- KDE は通知サーバーを備えており、通知は画面の右下に表示されます。
また、Deepin および GNOME Flashback も同様に通知サーバーを備えています。
スタンドアロン
他のデスクトップ環境では、ウィンドウマネージャやデスクトップ環境の自動実行を使って通知サーバーを起動する必要があります。
D-Bus で初めて呼ばれた時に通知サーバーを起動させるには、通知サーバー (notification-daemon パッケージなど) をインストールした後、以下のように設定を /usr/share/dbus-1/services
(またはユーザー個別に起動したい場合 $XDG_DATA_HOME/dbus-1/services
) に追加します:
org.freedesktop.Notifications.service
[D-BUS Service] Name=org.freedesktop.Notifications Exec=/usr/lib/notification-daemon-1.0/notification-daemon
通知サーバーは以下から選ぶことができます:
- Avant Window Navigator — AWN で使うことができる通知デーモンアプレット。
- Deadd Notification Center — Dnust にインスパイヤされた、通知センターが付いた通知デーモン。
- fnott — wlroots-based コンポジタのための軽量な Wayland 向けの通知デーモン。キーボードによって操作される。
- LXQt Notification Daemon — LXQt の通知サーバー。
- MATE Notification Daemon — MATE の通知サーバー。
- Notification Daemon — GNOME Flashback によって使われている通知サーバー。
- https://github.com/GNOME/notification-daemon || notification-daemon
/usr/lib/notification-daemon-1.0/notification-daemon
で手動で起動できます。
- Notify OSD — Unity の通知サーバー。
- statnot — 小さくて軽量な通知デーモン。ルートウィンドウのタイトルや標準出力、FIFO パイプなどに通知を出力できるので、タイル型ウィンドウマネージャと相性がとても良いです。
- sandsmark-notificationd — ミニマムな通知デーモン。ミュート機能をサポート。
- twmn — タイル型ウィンドウマネージャ向けの通知システム。
- wired — レイヤーブロックのカスタマイズ性が高い軽量な通知デーモン。Rust で書かれている。
- Xfce Notification Daemon — Xfce の通知サーバー。

ヒントとコツ
以前の通知を置き換える
Notifications can be replaced if their ID is known; if a new notification request specifies the same ID, it will always replace the old notification. (The libnotify bindings shown above handle this automatically.) Unfortunately notify-send does not report this ID, so alternative tools are required to do this on CLI. One capable CLI-tool is the notify-send.py python script, which provides notify-send syntax with additional ID-reporting and replacing capabilities.
However, with some notification servers (such as Notify-OSD), you can use the string:x-canonical-private-synchronous:
hint with notify-send to achieve the same result.
For example, to get a notification displaying time:
while true; do date=$(date) notify-send "$date" -h string:x-canonical-private-synchronous:my-notification sleep 1 done
ボタンを含める、閉じる/クリックを把握する
With the notify-send.py script, actions can be used to display buttons or to listen for the default-action of the notification (usually, when the user clicks on it) and the close-action. When the action-icons hint is set to true and the notification daemon supports this, the buttons will display icons instead of text. The script prints the action identifier or "close" to the command line when the corresponding event has occured. To listen for the default action (on-click), one has to use the action-identfier "default".
Example with icons on buttons:
notify-send.py "Buttons" "Do you like em?" --hint boolean:action-icons:true --action yes:face-cool no:face-sick
D-BUS サービスを備えば複数の通知サーバー
As described in the section Standalone, users can create a D-Bus service so that a notification server can be launched automatically. Some implementations already include the D-Bus service files. However, this causes a problem when multiple notification servers are installed and when some of them come with the service files. For example, installing both dunst and mako without explicitly specifying the desired server, D-Bus then chooses one for the users, and the decision is out of users' control. To avoid the situation, you can override the service used by creating the symbolic link $XDG_DATA_DIR/dbus-1/services/org.freedesktop.Notifications.service
pointing to the service you want to use, and then restart the session.
Troubleshooting
Applications hanging for exactly one minute
If applications hang when attempting to show notifications, it might be because of a notification service falsely advertising its availability through the D-Bus service.
For instance, suppose a user recently installed a KDE component that requires plasma-workspace, but the user is still running XFCE. In this case, the KDE notifier will be prioritized, but the user is not running it. The application will hang while waiting for the service, and only after a timeout will it fall back to xfce4-notifyd.
The most noticeable hanging might come from the volume indicator scroll adjustment.
If you are in this situation, you should have two notification handlers:
$ find /usr/share/dbus-1/services/ -name '*Notif*'
org.kde.plasma.Notifications.service org.xfce.xfce4-notifyd.Notifications.service
Of those two, one fails regularly after a 1-minute timeout, as seen in the journal:
# journalctl -g notif
[ press End to go to the end of the log ] Jul 01 09:40:49 laptop dbus-daemon[866]: [session uid=1000 pid=866] Activating service name='org.freedesktop.Notifications' requested by ':1.193' (uid=1000 pid=5432 comm="/usr/lib/xfce4/panel/wrapper-2.0 /usr/lib/xfce4/pa") Jul 01 09:41:49 laptop plasma_waitforname[6093]: org.kde.knotifications: WaitForName: Service was not registered within timeout Jul 01 09:41:49 laptop dbus-daemon[866]: [session uid=1000 pid=866] Activated service 'org.freedesktop.Notifications' failed: Process org.freedesktop.Notifications exited with status 1
Choosing the service you want to use as described in #Multiple notification servers with D-Bus services will fix the problem.
