Ubuntu16.04调整屏幕分辨率至1920×1080

1、ctrl+alt+t打开终端，输入命令“cvt 1920 1080”，返回

1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz

Modeline "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync

2、输入命令：“xrandr”，显示出当前可用的分辨率信息：

Screen 0: minimum 1 x 1, current 2560 x 1600, maximum 16384 x 16384
Virtual1 connected primary 2560x1600+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   800x600       60.00 +  60.32  
   2560x1600     59.99*
   1920x1440     60.00  
   1856x1392     60.00  
   1792x1344     60.00  
   1920x1200     59.88  
   1600x1200     60.00  
   1680x1050     59.95  
   1400x1050     59.98  
   1280x1024     60.02  
   1440x900      59.89

   1280x800      59.81  
   1152x864      75.00  
   1280x768      59.87  
   1024x768      60.00  
   640x480       59.94  
Virtual2 disconnected (normal left inverted right x axis y axis)
Virtual3 disconnected (normal left inverted right x axis y axis)
Virtual4 disconnected (normal left inverted right x axis y axis)
Virtual5 disconnected (normal left inverted right x axis y axis)
Virtual6 disconnected (normal left inverted right x axis y axis)
Virtual7 disconnected (normal left inverted right x axis y axis)

Virtual8 disconnected (normal left inverted right x axis y axis)

其中virtual1为显示器的名称。

3、增加显示模块，并设置开机启动，命令行输入“vim /etc/profile”,在末尾添加：

xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
xrandr --addmode VGA1 "1920x1080_60.00"

4、立马启用修改后的配置：

source /etc/profile

修改成功
