问题：蓝牙无法打开，无法建立连接。
证据：
$ sudo bluetoothctl
Agent registered
[bluetooth]# list
[bluetooth]# power on
No default controller available
[bluetooth]#
我尝试过/检查过的内容：
- 已关注拱门安装指南
- 已安装
bluez bluez-utils blueman - 重新启动
systemctl restart bluetooth.service - 检查 UEFI 是否启用了蓝牙硬件
- 检查
rfkill是否有被阻止的硬件，然后被阻止并重新解锁蓝牙 - 然
modprobe btusb - 启用
--experimental标志/etc/bluetooth/main.conf
