电源管理破坏了 KDE 上的蓝牙

我正在使用安装了 Unity 和 KDE Plasma 的 Ubuntu 16.10。我安装了 Ubuntu 16.04（来自我的 XPS 13 9360 开发者版的戴尔恢复映像），升级到 16.10 并安装kubuntu-desktop。

在我的登录屏幕（sddm 和 lightdm）上，我的蓝牙鼠标正常工作。但是使用 Plasma 登录后，安装了 Bluedevil 后我的蓝牙设备停止工作。蓝牙小程序显示蓝牙处于离线状态，复选框呈灰色。

给予power on的命令bluetoothctl

无法设置电源开启：org.bluez.Error.Failed

经过许多小时的试验，我发现 bluedevil 是问题的一部分。sudo apt remove bluedevil重启后，一切都正常（当然，除了缺少蓝牙小程序）。

这是我使用 KDE Plasma 登录后系统日志的结尾：

我如何才能找出电源管理为何会终止我的蓝牙设备（并修复它）？

更新：我将其blueman作为备用管理器进行安装，但我发现只需安装 blueman 即可“解决”该问题。

更新 2：Blueman 只是暂时修复了这个问题。禁用电源管理现在解决了这个问题，但这只是一种权宜之计。仍在寻找解决方案和解释为什么这个问题不会在 Unity 上发生。

答案1

我已禁用 TLP，问题就解决了。要禁用 TLP，请TLP_ENABLE=0在 中设置/etc/default/tlp。

它还解决了另外两个问题：
