蓝牙以前可以工作，但不知何故，连接后约 5 分钟就会断开与耳机的连接。我在网上搜索，尝试了很多方法，清除/重新安装了很多东西，现在蓝牙甚至找不到我的耳机了。

所以我基本上清除了所有与蓝牙有关的软件包，重新安装它们，然后重新启动。我现在可以连接到我的耳机，但 5 分钟后它仍然会与我的耳机断开连接。
经过更多的谷歌搜索，我发现 tlp 是罪魁祸首，所以我按照以下步骤操作本文
基本上将我的蓝牙适配器添加到 tlpUSB_BLACKLIST
sudo nano /etc/default/tlp
...
USB_BLACKLIST=”<Your usb adapter ID gotten from lsusb>”
...
