所以我进入 Ubuntu 12.10 中的系统设置，我想安装驱动程序，但在附加驱动程序下，我的 LAN 不起作用，甚至没有检测到我通过以太网线插入。我有一张 GTX 670M 和 3Gb GDDR5 显卡，我想使用它。只是需要帮助，对 Ubuntu 来说还很陌生。
好的，当我查看另一个问题时我做了sudo lspce -nn，这就是我得到的

如果还有其他需要，请告诉我。
答案1
您的 Atheros 卡未安装驱动程序。根据我从 lspci 输出获得的硬件 ID，我假设您有一张 Atheros Bigfoot Killer E2200 以太网卡，并且您的笔记本电脑似乎是 MSI Global GT70 0NC（不错！）游戏笔记本电脑。您需要安装 compat-wireless 驱动程序。如果您的机器可以访问互联网，请尝试按照此处提到的步骤操作：

这应该可以帮助您安装驱动程序，然后您可以将 LAN 电缆插入端口。我不认为这是网络管理器的问题。
希望这对你有帮助！:-)
PS：确保使用的是“eth0”而不是“etho”。
答案2
您的网络管理器有问题。您必须重新安装它。
在终端中运行以下命令
sudo apt-get install network-manager*
答案3
我假设你的笔记本电脑有 Intel HD 4000/3000 对吧（optimus）？如果是这样，不要安装附加驱动程序下的驱动程序，而是安装熊蜂，这样您就可以在 ubuntu 上启用 nvidia optimus。
