我设置了一个简单的脚本来向左或向右旋转屏幕（使用 xrandr），并且它还可以旋转笔记本电脑上的触摸板。这样，物理旋转笔记本电脑就可以让触摸板直观地工作。例如：
#rotate left
xrandr --output left
xinput set-prop "$TOUCHPAD" "Coordinate Transformation Matrix" 0 -1 1 1 0 0 0 0 1
但是，使用此命令无法正确旋转两指滚动手势。对于左旋转，我希望能够左右移动两根手指来控制垂直滚动，同样上下移动来控制水平滚动。
我是否需要通过 xinput 更改某个属性来改变两根手指滚动的方向？
以下是我的触摸板当前所有属性的列表：
