几周前，我决定冒险一下，在运行 Xubuntu 的 Lenovo T420 上安装不同的界面。在尝试后我决定放弃 Kubuntu（只是不是我的风格）并保留 Xubuntu 和 Ubuntu 与 Unity。完成此操作后，我注意到出现了一个问题：当我将笔记本电脑插入为其购买的联想基站时，电池充电指示灯不再正常工作。据我所知，它仍然通过底座充电，就像我使用接口包之前一样。当我使用电源线时，它似乎注意到充电水平的变化，但这样做并不可靠。如果我在插入电源线（而不是在底座上）的情况下取出电池，打开计算机，然后将电池放回原位，电量差异将开始显示在系统托盘中的电池指示器图标中。
无论我使用 XFCE 的电池指示器还是 Unity 中的电池指示器，都会发生这种情况。我在这里发现了一个类似的话题这，但那是在 Debian 和不同版本的 XFCE 上。
我最终可能会重新安装 Xubuntu 15.10 或 16.04 版本，这应该可以解决这个问题，但与此同时，我能做些什么来解决这个问题？

答案1
看起来你的UPower坏了。
Xfpm4 通过 dbus 对来自 UPower 的信号做出反应来调整图标。就是这样。如果 UPower 没有以正确的方式传达这一点，xfpm4 对此无能为力。最好请您的经销商解决此问题。
