![蓝牙驱动程序不工作](https://linux22.com/image/1016956/%E8%93%9D%E7%89%99%E9%A9%B1%E5%8A%A8%E7%A8%8B%E5%BA%8F%E4%B8%8D%E5%B7%A5%E4%BD%9C.png)
问题
我在我的 HP 笔记本 - 14-cf0013dx 上运行 Ubuntu 18.04.4,之前我必须手动安装 WiFi 和蓝牙驱动程序。
当我尝试启用蓝牙时,这发生。
我首先想到的是这是一个 GUI 错误,所以我尝试使用终端上的“bluetoothctl”命令连接我的蓝牙设备。当我运行 bluetoothctl 列出控制器时,什么都没有出现。当我尝试配对时,我收到一条消息,提示“没有可用的默认控制器”。
任何帮助和反馈都非常感谢。谢谢!
