![无法打开蓝牙,Ubuntu 18.04,华硕 Vivobook S400CA](https://linux22.com/image/902724/%E6%97%A0%E6%B3%95%E6%89%93%E5%BC%80%E8%93%9D%E7%89%99%EF%BC%8CUbuntu%2018.04%EF%BC%8C%E5%8D%8E%E7%A1%95%20Vivobook%20S400CA.png)
当我尝试打开蓝牙时,按钮变成橙色,但没有其他反应。它一直显示蓝牙已关闭。

答案1
我在使用华硕 Eee 和 Ubuntu 18.04.1 LTS 时也遇到了同样的问题。
对我有用的解决方案是使用以下命令重新启动驱动程序:
rmmod btusb
modprobe btusb
从错误报告中发现这一点:https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=894542
