我在 ubuntu bionic 上使用蓝牙键盘。问题是键盘会随机断开连接并重新连接，我必须等待它重新连接才能打字。我不知道这是否是电源管理的问题，但似乎 ubuntu 每次重新连接时都会重新创建一个新设备。
以下是我的 dmesg 输出：

有人注意到了这种行为吗？

我也遇到了这个问题，经过一番搜索后发现这是 Ubuntu 中一个未解决的错误：https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1385113
不过，这似乎与不同蓝牙设备之间的干扰有关。当我同时使用蓝牙键盘和蓝牙耳机时，这个问题非常突出，但如果我通过电缆连接耳机，问题就会消失。所以试试吧，希望底层错误能很快得到修复。
