Chromium をサービスとして実行できません。

パルスオーディオを実行する必要があるため、Chromeをサービスとして実行しようとしています。

サービスファイルは次のとおりです。

走っていsystemctl start kioskますが、何も起こりません。
ステータスオプションの出力は次のとおりです。

サービスを手動で実行すると、systemctl --user start kioskブラウザでサービスが開始されます。ブラウザを閉じるとブラウザが再起動します。

ただし、コンピュータを再起動すると、ブラウザは自動的に起動せず、dmesgまたはsyslogでエラーメッセージが見つかりません。

唯一の手がかりは次のとおりです。
