2、xrandr -s 0表示设置分辨率为1366x768 60.00*+
xrandr -s 1表示设置分辨率为1280x720 60.00
方法二、
添加自己想要修改的分辨率如cvt 1920 1200
1、cvt 1920 1200
# 1920x1200 59.88 Hz (CVT 2.30MA) hsync: 74.56 kHz; pclk: 193.25 MHz
Modeline "1920x1200_60.00" 193.25 1920 2056 2256 2592 1200 1203 1209 1245 -hsync +vsync
2、
xrandr --newmode "1920x1200_60.00" 193.25 1920 2056 2256 2592 1200 1203 1209 1245 -hsync +vsync
[root@localhost ~]# xrandr
Screen 0: minimum 8 x 8, current 1366 x 768, maximum 32767 x 32767
eDP1 connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 309mm x 173mm
1366x768 60.00*+
1280x720 60.00
1024x768 60.00
1024x576 60.00
960x540 60.00
800x600 60.32 56.25
如上改显示用的是DP1
则执行xrandr --addmode DP1 1920x1200_60.00
xrandr --output DP1 --mode 1920x1200_60.00
