我无法打开蓝牙，也无法显示。此页面上的所有按钮均无响应。我唯一能做的就是勾选复选框，但没有显示蓝牙状态。
我检查了我的 /etc/blueoth/main.conf。AutoEnable=true
我也尝试过命令：
rfkill block bluetooth
rfkill unblock bluetooth #Nothing changed or showed up
也
sudo rmmod btusb
>rmmod: ERROR: Module btusb is not currently loaded
lspci -nnk | grep -iA3 net; lsusb编辑：按建议添加输出
$ lspci -nnk | grep -iA3 net; lsusb

那是不是说我没有蓝牙适配器呢？
