Hi, To compile systemd notify plugin: --enable-systemd-notify
To start weston with the plugin: /usr/bin/weston --tty=1 --modules=systemd-notify.so The systemd-notify plugin will send a notification when weston startup is finished. You can use this notification to synchronize your application with weston.
