Ubuntu 分辨率更改 xrandr Failed to get size of gamma for output default

一，问题
版本信息描述： Ubuntu 16.04 LTS

安装了Ubuntu后分辨率和显示器不匹配。

使用了来自https://www.cnblogs.com/heenhui2016/p/8243103.html的方法

sudo vim /etc/xorg.conf

copy:

Section "Monitor"
        Identifier   "Monitor0"
        VendorName   "Monitor Vendor"
        ModelName    "Monitor Model"
        HorizSync   28.0 - 70.0
        VertRefresh     56.0 - 75.0
EndSection
 
 
Section "Device"
        Identifier  "VMware SVGA"
        Driver      "vesa"
EndSection
 
 
Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        Monitor    "Monitor0"
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes     "1920x1080_60.00"
        EndSubSection
EndSection

:wq!（保存，好像还不能自动切换分辨率，手动设置分辨率后可以
