我遇到了一个奇怪的新问题。我的蓝牙鼠标和键盘有时会重新连接。这很烦人，但并不新鲜，几秒钟后连接断开，然后重新连接。但几天后重新连接就不起作用了。鼠标或键盘确实重新连接了，但输入不再被识别（无法移动鼠标或无法用键盘打字）。我必须重新启动蓝牙服务或sudo service bluetooth restart手动断开并重新连接鼠标或键盘。
如果发生这种情况，系统日志没有帮助，不会有任何消息。
硬件：
- Dell XPS 13 9370（Ubuntu 16.04，带有最新 HWE 内核 4.15.x）
- 罗技 G604 Lightspeed 鼠标
- 罗技 G915 键盘
我可以检查哪些日志？有人遇到同样的问题吗？
顺便说一句，我也尝试了 4.15.x 的旧内核（因为这是一个相当新的问题），但没有用
编辑：同时我启用了蓝牙调试模式。这是发生这种情况时的系统日志输出（在本例中为鼠标）：

答案1
我的 Logitech MX Master 也遇到了同样的问题。在 bluez/libbluetooth3 更新到 5.37-0ubuntu5.3 后，这个问题开始出现。我恢复到 5.37-0ubuntu5.2，一切正常。
