数週間前、私はリスクを負い、Xubuntuを実行しているLenovo T420に別のインターフェースをインストールすることにしました。試した後、私はKubuntuを捨てて（私のスタイルではない）、XubuntuとUbuntuをUnityと一緒に保つことにしました。これを実行した後、問題が見つかりました。ノートパソコンを購入したLenovoベースステーションに接続すると、バッテリー充電インジケーターが正常に機能しなくなります。私が知っている限り、インターフェイスパックを使用する前と同様に、まだベースを介して充電されます。コードを使用すると充電レベルの変化に気づくようですが、安定していません。電源コードが接続されている間（ドックではなく）バッテリーを取り外し、コンピュータの電源を入れてからバッテリーを入れ直すと、充電差がシステムトレイのバッテリーメーターアイコンに表示され始めます。
XFCEのバッテリーインジケーターを使用しても、Unityのバッテリーインジケーターを使用しても、この現象が発生します。ここで同様のトピックを見つけましたこれしかし、これはDebianとは異なるバージョンのXFCEにあります。
おそらくXubuntu 15.10または16.04を再インストールすると、この問題は解決します。しかし、これまでこの問題を解決するにはどうすればよいですか？

UPowerあなたのものが壊れているようです。
Xfpm4はdbusを介してUPowerの信号に応答してアイコンを調整します。それはすべてです。 UPowerがそれを正しい方法で渡さないと、xfpm4はこれについて何もできません。この問題を解決するには、販売店に連絡するのが最善です。
