在ubuntu 16.04上使用Microsoft Designer键盘和鼠标（在dell xps 13上）
我有戴尔XPS 13的新开发者版本，它带有ubuntu 14.04 LTS。 由于新的LTS已经发布，我决定升级到16.04，它应该支持BLE（蓝牙低功耗）设备，如Microsoft Designer键盘和鼠标。 但我无法让它发挥作用。
如果我尝试配对鼠标，它会失败：

我想知道“SMP安全……”这条线是否重要？ 我找到了这个链接，正确答案的作者描述了他如何“修补”他自己的隐藏文件，但这样做没有帮助： Ubuntu 14.04 LTS上的Microsoft Designer Mouse（蓝牙4.0）
当尝试连接键盘时，结果和日志非常相似（只有地址更改），所以我在这里省略了它们。
希望有人对我有帮助吗？
提前致谢 ：）
我从17.04更新到最新的bluez版本。 它是根据debian bug票在那里修复的。 我刚刚手动下载了该文件。
