蓝牙无法在 ubuntu 18.04 LTS 上使用

我最近安装了 Ubuntu 18.04 LTS，并尝试了几种解决方案来解决此问题，但到目前为止没有任何效果。

以下是rfkill list

0: acer-wireless: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no

当我尝试时bluetoothctl，我得到了以下结果：

hozayfa@hozayfa:~$ bluetoothctl
Agent registered
[bluetooth]# power off
No default controller available
[bluetooth]#

输出dmesg | grep Blue

hozayfa@hozayfa:~$ dmesg | grep Blue

此行显示 BT 已关闭

[蓝牙]# 关机

检查您的计算机是否有物理开关来打开它，或者检查 BIOS 是否有办法打开和关闭它。

应该支持该卡的驱动程序。但它好像坏了。
