Ubuntu 14.04 LTS - 蓝牙未检测到任何设备

我有一台 HP Probook 笔记本电脑。自从我安装了 ubuntu 14.04 LTS 后,我的笔记本电脑就无法使用蓝牙连接任何设备。其他设备也无法检测到我的笔记本电脑。由于我只使用 ubuntu 14.04 LTS,因此我无法在笔记本电脑上启动 Windows。我尝试了不同在线论坛上提供的许多解决方案。但这些对我没有帮助。我的硬件和驱动程序设置正确。但问题仍然存在。这些问题困扰了我很久。请帮我解决这个问题。问候

这些是建议命令的输出。

答案1

看起来你从未更新过你的系统。你的内核很老,不支持该设备。该支持已由这次提交

在终端中运行

sudo apt-get update
sudo apt-get upgrade

您应该获取3.13.0-126支持该设备的内核。
