ubuntu - 哪个 xinput 设置会反转鼠标滚轮的方向？

Question

我正在尝试遵循 this 的建议问题，使用 xinput为我的鼠标滚轮启用自然滚动的工具。

我通过 $ xinput list 列出我的输入设备并获得以下信息:

$ xinput list
⎡ Virtual core pointer                          id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ SynPS/2 Synaptics TouchPad                id=11   [slave  pointer  (2)]
⎜   ↳ TPPS/2 IBM TrackPoint                     id=12   [slave  pointer  (2)]
⎜   ↳ Dell Dell USB Optical Mouse               id=14   [slave  pointer  (2)]
⎣ Virtual core keyboard                         id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ↳ Power Button                              id=6    [slave  keyboard (3)]
    ↳ Video Bus                                 id=7    [slave  keyboard (3)]
    ↳ Sleep Button                              id=8    [slave  keyboard (3)]
    ↳ Integrated Camera                         id=9    [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard              id=10   [slave  keyboard (3)]
    ↳ ThinkPad Extra Buttons                    id=13   [slave  keyboard (3)]

相关设备是 Dell Dell USB Optical Mouse id=14 .我通过 $ xinput list-props 14 列出了该设备的属性，并得到

$ xinput list-props 14
Device 'Dell Dell USB Optical Mouse':
        Device Enabled (140):   1
        Coordinate Transformation Matrix (142): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000

        Evdev Wheel Emulation Button (322):     4
        Evdev Drag Lock Buttons (323):  0

我可以更改其中哪些(如果有)来反转滚轮方向？

我尝试调整 Evdev Axis Inversion (306)属性通过命令 $ xinput set-prop 14 306 1, 1 ，但这显然是针对鼠标移动方向，而不是滚轮方向——我不得不把它改回来。

做任何这些 xinput设置反转滚轮方向？如果没有，那么也许我需要尝试另一种方法。我的操作系统是 Ubuntu 16.04.2 LTS。

Answer 1

尝试运行

$ xinput set-prop 14 311 -1 1 1

将“Evdev 滚动距离”设置为垂直移动的负值。
