蓝牙在 Kali Linux 上不起作用

Question

好吧，我遇到了蓝牙总是关闭的问题。我转到配置-> 蓝牙，每次我尝试将其关闭时，都会在一段时间后返回关闭状态。我试过这个命令：

aptitude install bluetooth

然后跑了

/etc/init.d/bluetooth start

之后我跑了/etc/init.d/bluetooth status，这就是显示：

? bluetooth.service - Bluetooth service
   Loaded: loaded (/lib/systemd/system/bluetooth.service; disabled; vendor preset: disabled)

我的电脑是索尼 VAIO SVF15A17CLV。

谢谢！！

编辑：运行 service restart 命令后，你们中的一些人建议我得到以下输出：

看起来更好，但它仍然无法正常工作。当我进入蓝牙设置时，它总是关闭。按开始后，它保持如下图所示：

PS：我知道这不是硬件问题，因为如果我使用 Windows 10 启动它可以正常工作。

我相信我们遇到了同样的问题。我的蓝牙无法打开并保持在关闭位置。这是我为解决此问题所做的工作：

service bluetooth restart

这重新启动了蓝牙服务，我能够打开它并保持打开状态。我还能够看到蓝牙设备并再次连接到我的耳机。
