我无法找到这个确切的问题,但有一个类似的问题没有答案Ubuntu 20.04 重启后无法连接已配对的蓝牙鼠标
重启后,Ubuntu 20.04 不会自动重新连接键盘。选择“连接”后,它只会旋转,永远不会连接。我让它工作的唯一方法是移除设备并重新添加,然后它就可以正常工作,直到下次重启。
不确定需要什么,但是这是我的输出sudo dmesg | grep -i blue

我没有安装 Blueman,不确定这是否有帮助,因为上述用户在解决蓝牙鼠标的类似问题时没有成功。
Logitech 论坛上没有这样的问题。任何建议都会有帮助,因为我可以在每次重启后通过添加设备进行连接,但如果它自动重新连接会更好,即使只是使用“连接”按钮。
