仅从挂起状态唤醒后才能识别蓝牙

我的蓝牙只有在挂起计算机后才能工作。启动计算机后，rfkill list all 的输出如下：

  $ rfkill list all
  0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no

然后我将其暂停（这里我使用 pm-suspend，但 GUI 方法也可以）

  # pm-suspend

瞧，rfkill 再次列出所有内容

  $ rfkill list all
  0: phy0: Wireless LAN
       Soft blocked: no
       Hard blocked: no
  1: hci0: Bluetooth
       Soft blocked: no
       Hard blocked: no

lspci 的输出是

您知道这可能是什么原因造成的吗？

谢谢！

答案1

因此，从 16.04 升级到 18.04 时，问题就解决了。抱歉，我无法提供更多详细信息。以前（几年前）当我在同一台计算机上使用 linuxmint 时，我没有遇到这个问题，而当我切换到 ubuntu 时（我认为当时是 16.04），所以一定有办法解决这个问题。

祝你好运
