![Ubuntu 20.04 未找到蓝牙](https://linux22.com/image/945756/Ubuntu%2020.04%20%E6%9C%AA%E6%89%BE%E5%88%B0%E8%93%9D%E7%89%99.png)
我的 PC 配有 wifi/蓝牙卡。wifi 工作正常。蓝牙很好,但今天它在我的 ubuntu 上不起作用,重新启动也不起作用。在 ubuntu20.04
设置 GUI 上,它显示:
No Bluetooth Found
Plugin a dongle to use Bluetooth
虽然我相信没有硬件问题。我主要怀疑是 ubuntu 设置中心的问题。
努力:
sudo rfkill unblock bluetooth
sudo rmmod btusb
sudo systemctl restart bluetooth
sudo systemctl start bluetooth
。
sudo /etc/init.d/bluetooth restart
Restarting bluetooth (via systemctl): bluetooth.service.
。
sudo hcitool dev

答案1
最终通过关闭电脑等待 30 秒然后重新启动解决了问题。
更新后仅进行热重启并不能解决问题。
