Ubuntu 20.04 在挂起后无法识别内部蓝牙

我有一台装有 Ubuntu 20.04 LTS 的华硕电脑。我发现我的电脑挂起后蓝牙无法工作。我发现的唯一解决办法是重新启动电脑。我尝试过这个问题的解决方案Ubuntu 18.04 从睡眠状态恢复后蓝牙无法工作，但它不起作用。我已经从 bluez 获得了5.53-0ubuntu3.1比出现问题的版本更高的版本。我的问题与此有关问题，但无人回应。

我非常感谢任何帮助，因为我远程工作，所以需要一直戴着耳机。

感谢您的时间。

答案1

今天下午我对这个问题做了一些测试，怀疑 ubuntu 没有正确关闭蓝牙。

尝试修改：/etc/bluetooth/input.conf，取消注释：

空闲超时=5

用户空间HD=true

到目前为止，已使用我的 JBL GO 3 进行了测试，无论我做什么，JBL 都会再次连接。

也许可能需要更多的测试，我会尽量让你知道:)
