蓝牙问题-每 2~3 秒持续开启/关闭一次?

蓝牙问题-每 2~3 秒持续开启/关闭一次?

Ubuntu 版本:18.04 内核:4.15.0-45-generic

我不知道原因,但我的 ubuntu 机器上的蓝牙突然无法使用。正如您在系统日志中看到的,它无限重复。每隔 1~2 秒就会发生一次。现在太疯狂了。

上周它运行良好。但今天我意识到它现在有问题。

有人可以帮忙吗?

答案1

我解决了类似问题 我对与 PS3 操纵杆配对进行了一些更改后,蓝牙完全不工作

  • 只需关闭系统:sudo shutdown -h now
  • 拔掉所有连接的电缆,如电源、HDMI、CAT5.E,甚至键盘和鼠标 USB
  • 几秒钟后,再次插入,最终它工作了

我回答了谁遇到过类似的问题

答案2

我通过将内核更新到最新版本(4.19 到 5.9)、关闭、拔下所有 USB 设备、重新启动并逐个插入设备来解决了该问题。
