概述
我有一台 ThinkPad 笔记本电脑，可以双启动到 Windows 11 和 Fedora 37。我以前可以在 Fedora 上使用蓝牙，但现在由于某种原因无法使用。我不知道到底是什么原因造成的，但现在当我尝试进入设置并打开蓝牙滑块时，滑块仍然是灰色的，并且蓝牙无法打开。当我启动到 Windows 时，蓝牙工作正常。蓝牙也出现在快速设置中，但当我单击它时它没有任何反应。

其他注意事项
我还尝试过重新启动蓝牙服务，禁用它并在重新启动后手动启动它。我确保在 Windows 控制面板设置中禁用安全启动并禁用快速启动，这是另一个论坛建议的。我用 阻止和解除阻止蓝牙sudo rfkill block bluetooth && sudo rfkill unblock bluetooth。如果需要任何其他信息，请告诉我。
答案1
问题似乎是我使用的网卡（高通）不能在 Linux 上开箱即用（至少不能用于蓝牙 - WiFi 可以工作）。我做了一些搜索，看看是否可以找到高通卡的驱动程序，但什么也没找到。
我的解决方案是花大约 20 美元购买一张 Intel 卡，它开箱即用，支持 Linux。安装该卡后，蓝牙可以在 Windows 11 和 Fedora 37 上运行。对于我的 ThinkPad 来说，安装非常简单。
答案2
据我所知，这个问题似乎在大多数 Linux 发行版上都很普遍。我还没有找到真正有效的“修复方法”。我自己也遇到同样的问题。
您会发现围绕此问题还有许多其他问题。
它通常可以归结为“操作系统可以看到它的存在（请参阅“lsmod”），但不允许它以任何方式实际运行。”
来自各地的建议包括：
- 运行“rfkill unblock（您的蓝牙设备）”（运行“rfkill list”以显示设备，尽管蓝牙开发人员可能不会显示...）
- 尝试安装驱动程序
- 运行“systemctl启用蓝牙”
- 运行“服务蓝牙启用”
还有其他一些人。
我已经尝试了尽可能多的方法，但没有一个对我有用。
也许你会有更好的运气。如果您发现其他有效的方法，请告诉我。
