ubuntu15.04由于安装显卡驱动导致的有线网连接问题

[killer12]

我是ubuntu15.04系统，原来是无线有线都可以上网的，后来因为需要安装nvida的显卡驱动，于是按照
http://www.allaboutlinux.eu/remove-nouv ... ntu-15-04/
卸载了原来的nouveau驱动，重新安装了cuda7.5，于是问题就来了。

有线网刚开始是可以ping通局域网的，但是只要是任何非终端的网络连接操作(打开浏览器或者连接打印机等），网络连接就有问题，就会ping不通局域网其他主机，更不用说连外网。

问题的确是显卡驱动引起的，因为重装了几次系统都是显卡驱动装好以后有线网络连接就坏了。无线网没有问题。

请指教应该如何解决呢？

1. 把下面指令 複製 貼進終端機 執行
1-1. uname -r
1-2. sudo lspci -knn
1-3. sudo lshw -numeric -class video
1-4. sudo ubuntu-drivers devices
1-5. sudo lshw -numeric -class network
1-6. sudo ifconfig -a
1-7. sudo route -nv
把結果直接 選取/複製 貼上來

问题的确是显卡驱动引起的

2. 有沒有明確證據或網頁 可以參考

[killer12]

倒是没有什么具体的证据，只是我重装了几次系统，刚重装上是好的，只要安装完显卡驱动就不能连了，也没有做别的操作，所以就推断是显卡驱动导致的。
