1920是宽x，1080是高y，60是刷新频率。
| xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsyn |
--newmode后面的参数是cvt命令的Modeline之后的内容。
| xrandr --addmode Virtual1 "1920x1080_60.00" |
Virtual1是当前显示设备的名称，可以直接输入xrandr命令查看所有的显示设备。"1920x1080_60.00"是之前新建的模式的名称。
| xrandr -s 1920x1080_60.00 |
如果要选择模式已经存在，直接执行第4步即可。执行xrandr命令可以查看当前设备、选择的模式等信息。
