我在 Compaq Presario 510 上使用 Zorin os 5，当时我的内置蓝牙工作正常，但在安装 Ubuntu 14.04 后，它说
未找到蓝牙适配器。
我可以通过重新安装 Zorin 5（蓝牙再次工作），然后重新安装 Ubuntu 14.04（未找到蓝牙适配器）来重现此问题。

答案1
我终于打开了蓝牙，它能够找到我的 Android 设备并与其配对。
我启动了 Zorin 5 安装光盘并选择无需安装即可运行。底部面板上的蓝牙图标显示蓝牙已关闭，因此我将其打开，蓝牙正常工作，我可以找到蓝牙设备。
我关闭了 Zorin 5 并打开了蓝牙，然后退出了 Zorin 5，取出了安装光盘并再次打开了笔记本电脑。我的 Ubuntu 15.04 上的蓝牙开始工作了。我可以与它配对并共享文件。
我无法使用我的 Android 设备通过蓝牙联网，而在 Zorin 中可以做到这一点，而且我无法传输大文件（超过 5 MB），但我很高兴。
