好吧，就在几天前，我知道我的 manjaro 系统上的蓝牙可以正常工作。但现在却不行了。

首先它没有被阻止（虽然现在每次我重新启动时都必须解除阻止）

 rfkill list all     
0: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no

bluetoothctl不是特别好

bluetoothctl      
[bluetooth]# Agent registered
[bluetooth]# show
No default controller available
[bluetooth]# list
[bluetooth]#

据我所知，蓝牙服务没有任何实际问题

systemctl status bluetooth.service                                                                                  ✔  46s 

我得到了一些东西dmesg，但我真的不明白它是什么

sudo dmesg | grep  Bluetooth                                                                                                ✔

我尝试让它再次工作，插入了一个 USB 蓝牙适配器，但没有作用。

我也尝试安装一些驱动程序（以前不需要）

yay -S rtl8821ce-dkms-git

我已经重新安装了所有相关bluez

当然，我也尝试过重启，但没有成功

manjaro
