蓝牙无法在 ubuntu 18.04 上使用

我遇到了与报告的问题类似的问题这个线程。，但我正在运行 Bionic Beaver

我的机器是戴尔 XPS 13。Wifi 运行良好。

在设置 -> 蓝牙中，我被告知No bluetooth found, plug in a dongle

我尝试将屏幕左上角的按钮从关闭状态切换为打开状态，但无法成功

上述帖子中建议的以下解决方案没有任何作用

rfkill unblock bluetooth
systemctl enable bluetooth.service
systemctl start bluetooth.service

以下是其他帖子中请求的各种命令的输出：
