xrandr: Failed to get size of gamma for output default

新装的Ubuntu14.04分辨率只有两种1024x768和800x600，没有我想要的1920x1080,之前一直没弄清楚是什么问题，就按照网上的各种教程弄，

按照这个系列的命令：

xrandr --newmode。。。

但是一直不成功，报错：

xrandr: Failed to get size of gamma for output default
X Error of failed request: BadName (named color or font does not exist)

弄了很久也没解决，最后发现其实很简单，是驱动没装好的问题。

在软件更新（soft updater）里面的setting->Additional Drivers选择Using NVIDIA binary driver-version 367.57 from nvidia-367这一项进行安装即可。

重启电脑发现已经搞定了！
