蓝牙管理器窗口无法打开

Question

我在 Raspberry Pi 上使用 USB 蓝牙适配器。到目前为止，我设法连接设备并使用终端进行配对。但桌面/GUI 蓝牙管理器无法打开。我可以在桌面上看到该图标，正如您所看到的，我什至可以右键单击它来查看选项，但没有一个打开。我已经尝试过所描述的一切这里没有成功。任何想法为什么会发生这种情况以及我该如何解决它？

更新：按照@Patrick的建议，我做了一个pkill blueman-appletandblueman-applet并得到了以下输出：

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

Answer 1

这并不是真正的修复，但尝试单击“关闭蓝牙”，然后尝试打开蓝牙管理器。它应该提示您重新打开蓝牙，然后管理器将打开。这对我有用。

Answer 2

我遇到了同样的问题（如上面的评论所述）。我在 Pi 2 上使用可插拔 USB-BT4LE 蓝牙适配器。此页面 (http://plugable.com/2013/12/10/using-the-plugable-usb-bt4le-bluetooth-adapter-with-the-raspberry-pi）给出了答案：

如果蓝牙实用程序没有看到蓝牙适配器，请尝试以下命令：

sudo nano /etc/group

{将第 8 行从“lp:x:7:”更改为“lp:x:7:pi”保存并退出}

sudo reboot

这对我来说很有效！
