在 Linux Mint 上找不到蓝牙适配器

我有一台 HP Pavilion-15 笔记本电脑，采用双启动配置，配备 Linux Mint 和 Windows，并且长期以来一直遇到蓝牙问题。最近我的电脑根本无法检测到任何蓝牙适配器。我已经尝试了所有方法，查看了多个论坛，但没有效果。

单击“适配器”选项后，blueman 的屏幕截图如下所示：

我卸载并重新安装bluez，安装blueman，但没有效果。我尝试过的一些输出如下：

  • hcitool dev没有提供蓝牙设备。任何其他 hci 命令也没有。

  • bluetoothctl输出在这里：

    Agent registered
[bluetooth]# show
No default controller available
[bluetooth]#

  • rfkill没有列出蓝牙

  • systemctl bluetooth status输出

  • 在 Windows 上，我能够正常检测并连接蓝牙设备。事实上，我有一种感觉，问题是在我启动 Windows 一次后就开始出现的。我在 Windows 上禁用了快速启动并进行了冷重启。没有解决。

我已经束手无策了。请提出解决此问题的建议。谢谢。

答案1

我看到模块 btusb 没有显示在 lsmod 中。尝试sudo modprobe btusb

答案2

试试这个：（sudo systemctl enable bluetooth.service确保你已经安装了蓝牙包）
