Ubuntu 20.04 掛起後無法辨識內部藍牙

我有一台裝有 Ubuntu 20.04 LTS 的華碩。我發現我的藍牙在電腦暫停後無法工作。我找到的唯一解決方案是再次重新啟動電腦。我已經嘗試過這個問題的解決方案Ubuntu 18.04 從睡眠狀態恢復後藍牙無法運作，但它不起作用。我已經有一個來自 bluez 的5.53-0ubuntu3.1比有問題的版本更好的版本。我的問題與此有關問題，但沒有人回應。

我真的很感謝任何幫助，因為我遠端工作並且需要一直戴著耳機。

感謝您的時間。

答案1

今天下午我對這個問題做了一些測試，懷疑 ubuntu 沒有正確關閉藍牙。

嘗試修改：/etc/bluetooth/input.conf，未註解：

空閒超時=5

使用者空間HD=true

到目前為止，已經用我的 JBL GO 3 進行了測試，無論我做什麼，JBL 都會再次連接。

也許它可能需要更多測試，我們會盡力讓您知道:)
