错误描述
我想使用我的蓝牙鼠标。就这么简单。所以我将鼠标与我的笔记本电脑连接起来 - 起初它工作正常，但几分钟后它突然停止工作，直到重新启动才能启动。
所以我重新启动了笔记本电脑，系统启动时一切正常，但几分钟后我的鼠标又停止工作了。

答案1
尝试使用我的 Logitech K380 蓝牙键盘时，我遇到了与 Soraphis 相同的问题。从我的系统中卸载 TLP 最终为我解决了这个问题。
如果已安装 TLP，请尝试禁用或卸载它。
答案2
由于无法到达 hci0：
hciconfig hci0 up
可以达到目的。
答案3
bluethoothctl不确定它为什么会这样，但我通过运行、打开power off、然后power on（失败）、使用退出并重quit试，power off使它无需重新启动就可以工作power on。
user@ubuntu:~$ bluetoothctl
[bluetooth]# power off
Changing power off succeeded
[bluetooth]# power on
