藍牙管理器視窗無法開啟

2024-4-19 • tag-icon

我在 Raspberry Pi 上使用 USB 藍牙轉接器。到目前為止，我設法連接設備並使用終端進行配對。但桌面/GUI 藍牙管理器無法開啟。我可以在桌面上看到該圖標，正如您所看到的，我什至可以右鍵單擊它以查看選項，但沒有一個打開。我已經嘗試過所描述的一切這裡沒有成功。任何想法為什麼會發生這種情況以及我該如何解決它？

更新：按照@Patrick的建議，我做了一個pkill blueman-appletandblueman-applet並得到了以下輸出：

pi@raspberrypi ~ $ pkill blueman-applet
pi@raspberrypi ~ $ blueman-applet
Xlib:  extension "RANDR" missing on display ":1.0".

答案1

這並不是真正的修復，但請嘗試點擊“關閉藍牙”，然後嘗試開啟藍牙管理器。它應該提示您重新打開藍牙，然後管理器將會開啟。這對我有用。

答案2

我遇到了同樣的問題（如上面的評論所述）。我在 Pi 2 上使用可插拔 USB-BT4LE 藍牙轉接器。http://plugable.com/2013/12/10/using-the-plugable-usb-bt4le-bluetooth-adapter-with-the-raspberry-pi）給了答案：

如果藍牙實用程式沒有看到藍牙適配器，請嘗試以下命令：
sudo nano /etc/group
{將第 8 行從「lp:x:7:」改為「lp:x:7:pi」儲存並退出}
sudo reboot

這對我來說很有效！
