虚拟机centos添加分辨率

由于屏幕分辨率是1920X1080,但是虚拟机中的centos的分辨率设置中没有这个值,因此需要添加一个。
在终端中输入如下命令:
1、cvt 1920 1080
得到:

# 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xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync(后边部分即步骤1中得到的结果去掉modeline)
3、sudo xrandr --addmode Virtual1 "1920x1080_60.00"
其中的Virtual1是输入命令xrandr后得到的(connected前边的那个):

[admin@localhost ~]$ xrandr
Screen 0: minimum 1 x 1, current 1920 x 1200, maximum 4096 x 4096
Virtual1 connected primary 1920x1200+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   800x600       60.00 +  60.32

   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  
   1280x960      60.00  
   1360x768      60.02  
   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)

运行结束后在设置中的即可找到对应分辨率选项,选择应用即可。
