![为什么设置双启动后以太网不工作?](https://linux22.com/image/883573/%E4%B8%BA%E4%BB%80%E4%B9%88%E8%AE%BE%E7%BD%AE%E5%8F%8C%E5%90%AF%E5%8A%A8%E5%90%8E%E4%BB%A5%E5%A4%AA%E7%BD%91%E4%B8%8D%E5%B7%A5%E4%BD%9C%EF%BC%9F.png)
因此,我一直在台式机的单独 SSD 上设置 Ubuntu 14.04,以进行一些机器学习开发。每当我启动另一个时,我都会手动断开 Win10 端或 Linux 端的连接,但我最近更新了 grub,以便能够更方便地进行双启动。
启动 Windows 并返回 ubuntu 后,我开始遇到以太网连接问题,甚至以太网现在根本无法工作,而且 wifi 也时断时续。
以下是一些输出:

似乎有很多这样的帖子,我已经浏览了 Google 上出现的前六篇帖子。此外,第一次发生这种情况时,将 NetworkManager.conf 行从“managed=false”更改为“true”可以完美解决此问题。在启动 Windows 并返回 ubuntu 后,情况似乎变得更糟。
哦,现在我启动时还会收到多个“检测到系统软件问题”消息。
谢谢你的帮助!
