Ubuntu14.04 双屏设置

[Lehyu]

首先，在windows系统下可以双屏显示。
然后，在Ubuntu系统下使用开源驱动（nouveau）可以监测到两个显示器，但是副显示器黑屏

DVI-I-0 connected
VGA connected

最后，安装Nidia驱动后，只能监测到一个显示器。

   640x480        59.9  
   512x384        60.0  
   400x300        72.2  
   320x240        60.1  
DVI-I-1 disconnected (normal left inverted right x axis y axis)
DP-0 disconnected (normal left inverted right x axis y axis)
DP-1 disconnected (normal left inverted right x axis y axis)

请问以下各位大神，应该怎么解决在Ubuntu系统下使用双屏这个问题？

我想闹明白如何使用三屏，我不会，但我猜想可能需要什么特别的工具，不单纯只是显卡驱动的问题！

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