我曾经在同一台笔记本电脑上安装过 Windows，并且蓝牙运行良好，但是在安装 Ubuntu 15.10 后，它无法识别硬件，我该怎么做才能获得正确的驱动程序？
这是我的 Acer R3 - 431 系列的硬件信息。

在终端中，请输入 lspci 并粘贴结果，以便社区能够帮助您找到特定的驱动程序。您可能没有兼容的卡，就像我的情况一样。我最终为我的卡订购了兼容的 wifi/bt 卡。
因此，您似乎拥有 Qualcomm Atheros QCWB335，它在同一张卡上同时支持 bt 和无线功能。好消息是，您的卡通过内核使用 ath9k 驱动程序获得支持。不太好但仍然好的一点是，要启用 bt，您必须手动启用卡上的共存功能。如果一切正确，并且运气好的话，modprobe ath9k btcoex_enable=1在终端中运行将启用共存并使其运行。
$$ 我该怎么做？$$ 你能解释一下吗？
*在终端中只需输入modprobe ath9k btcoex_enable=1并按回车键。
