蓝牙在 Linux Mint 18.2 上不起作用

我以前没有在Linux系统上使用过蓝牙，但我现在想使用它。我尝试使用它，但根本不起作用。以下是一些信息：

dmesg | grep -i bluetooth

我已尝试按照下面用户 Goro 的建议编辑 .config 文件。我还卸载了 Blueberry 并安装了 Blueman，希望它能起作用。我在谷歌上进行了广泛的搜索，发现很多用户都面临类似的问题，这些问题在重新启动后可以自行纠正。我的情况没有发生这种情况。我的内核已更新到软件管理器下提供的最新版本。

编辑：我认为内核 4.15 及更高版本已停止使用蓝牙。我在某个地方读过它。无论如何，它仍然不起作用，我现在放弃了。

正如建议的Linux Mint 论坛，您可以尝试以下操作：

-Change #AutoEnable=false to AutoEnable=true in the /etc/bluetooth/main.conf (notice new line is un-commented)
-Unpair the headset
-Restart the bluetooth service sudo /etc/init.d/bluetooth restart
-Pair your headset again and connect it
-Go to sound settings. From the output device tab you should now see the headset listed along with other output device like internal speakers
-Choose it as the sound output device.
