睡觉后，蓝牙无缘无故地再次工作......也许是圣诞魔法......
我的蓝牙突然停止工作。
在设置中，我什至无法访问打开或关闭它的按钮。
命令systemctl status bluetooth
给我
➜ systemctl status bluetooth

之后
sudo modprobe -r btusb
sudo modprobe btusb
systemctl restart bluetooth
给systemctl status bluetooth
我

蓝牙设置上的按钮enable再次出现，但没有任何反应...
但现在我可以做bluetoothctl --monitor，list结果为 0。与devices我有No default controller available。
冷重启也无济于事。
什么都开放rfkill list
