先感谢各位点进来围观我的问题。

---------------正文------------------------
最近新买了 xps15,安装了 manjaro 后发现只要和蓝牙耳机配对上了，重启之后蓝牙设备就直接没有了。不过其中我折腾时候重装了几次系统（体验一下不同的桌面环境，其实是因为 kde 不知道为什么卡成狗）。我尝试用 blueman 或者 bluetoothctl 启动蓝牙，但是无效。内核也开启了 btusb，还是不行。

同样的耳机在我的台式机上使用完全没有这个问题。蓝牙适配器和 wifi 是 intel 8260 AC。

个人怀疑是网卡驱动问题导致，因为台式机最后更新的日期是在 8 月初。不知到各位有什么想法和建议可以提供给我。

人生苦短

intel 的应该没有什么问题。我之前一台 13 也是蓝牙没问题，你可以看一下 arch 的 wiki

人生苦短 换黑苹果把 (滑稽

好像是蓝牙驱动的问题 去官网下载一个最新的蓝牙驱动试试

黑苹果好用吗？

比起我折腾的 linux 是的


今天无缘无故又好了，尴尬。我觉得是驱动问题，我所有解决方案都是看 arch 的 wiki 的。而且好像 killer 网卡也没有 Linux 的驱动，迟点把无线网卡换成 Intel 好了


我已经厌倦 macos 了，所以才买 XPS 装 Linux。虽然 Apple 对于 hackintosh 也没做太多管制。但如果你们公司客户是 Apple，你敢拿着一台 XPS 装着 hackintosh 和他讲报告？当然，这是一台私人电脑，但还是别让客户发现连累公司。

xps 兼容 linux，除了你这个蓝牙问题，还有其他问题么？


暂时还没发现，acpi 有些参数错误不影响启动，但耗电有点厉害，发热也很厉害，不过可以降压限制频率提高续航，一般使用续航大概 3-4 小时，也要看用什么桌面环境。此外键盘左下角发热蛮明显的，不知道 dell 塞了什么元器件。

参考 https://hr98.xyz/windows-linux-doublepair-bluetooth-mouse/
我解决蓝牙鼠标配对丢失问题，用的是 XPS15-9560(你机型的前代)，Intel 8260AC 的 WLAN/BT 卡
如果你不需 Windows/Linux 共用蓝牙设备，只需要读到"2. 在 Linux 中配对" 即可。

另:(原装的)Killer 1535 能在 Linux 正常使用(Ubuntu 18.04.1，4.15 内核； RHEL 等用的 3.10 系内核不一定)
