我在 Dell XPS 15 9520 上安装了 Kubuntu 22，当我断开电源线时，笔记本电脑无法识别。它只显示“已连接但未充电”。所以现在发生了多次，我没有收到电池电量不足的通知，一直耗尽电量直到笔记本电脑关机 - 这对电池寿命不利。
我尝试acpi_listen在控制台上调用，电源断开事件实际上是由内核发送的。
ac_adapter ACPI0003:00 00000080 00000000
battery PNP0C0A:00 00000080 00000001
sudo journalctl --follow连接或断开电源线时通话不显示任何内容。
调用upower -d显示以下输出：

有什么想法可以让它识别电源断开吗？
答案1
问题出在显示电池指示器的 GUI 上。执行sudo apt install kde-full或使用特定软件包来修复此问题。
正如您在问题中所写，内核和后端不是问题。ACPI 正确获取了消息。upower 正确报告了设备的当前状态battery_BAT0为percentage: 100%和icon-name: 'battery-full-charged-symbolic'。
因此问题出在您的用户空间桌面环境中。插入和拔出电源线时通常会有声音，因此请确保您没有禁用该功能。任务栏电池指示器在电量达到 100% 时会自动隐藏和取消隐藏，因此请单击^图标将其取消隐藏。
电池状态指示器小程序本身由软件包提供，plasma-workspace-data因此它不应该是缺失的。但是，它从 KDE 的电源管理守护程序 PowerDevil 获取数据。最小 KDE 安装可能不包含此软件包，如果您不想安装所有 KDE，您可以尝试只安装kde-plasma-desktop并重新登录。
