蓝牙已禁用且未显示在 LSPCI - ASUS G750JM 中

调制解调器在 14.04 上安装正确，在安装 ubuntu 时可以正常工作。它是 Broadcom 调制解调器，与 Broadcom 蓝牙卡绑定。但蓝牙在 14.04 上不起作用。Ubuntu 说它已被禁用，我该怎么做才能解决这个问题？它没有说它不存在，只是说即使我打开它，它仍然被禁用。

更新：我通过运行以下命令删除了华硕蓝牙的软块：

$sudo modprobe -b asus-wmi
$rfkill unblock all

但它在设置中仍然被禁用，我无法使用它，而且过了一会儿它又恢复到禁用状态

我是否可以假设，由于列表中没有列出蓝牙，Ubuntu 只是没有意识到我有蓝牙设备？这可以解释为什么我几乎尝试了所有方法来启用它，但都不起作用。请帮忙。

更新：

由于升级到 14.10 蓝牙只要我rfkill unblock all

更新：

现在，自从我删除了 ubuntu 并重新安装了 14.10 后，它就可以正常工作了

如果你在 dash 中输入“蓝牙”并打开蓝牙应用程序，你会看到类似下面的屏幕截图的内容，它说

蓝牙已禁用

在此处输入图片描述

您需要运行rfkill unblock 3，然后转到蓝牙应用程序窗口并将ON/OFF按钮拖到右侧以打开蓝牙ON，此外，如果您想让其他设备看到您的蓝牙设备，您需要打开ON可见性模式。

在此处输入图片描述

如果你使用终端检查，rfkill list 3你会看到蓝牙设备现在ON
