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

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
