【问题描述】：

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

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 Middle Button Timeout (313):      50
        Evdev Third Button Emulation (314):     0
        Evdev Third Button Emulation Timeout (315):     1000
        Evdev Third Button Emulation Button (316):      3
        Evdev Third Button Emulation Threshold (317):   20
        Evdev Wheel Emulation (318):    0
        Evdev Wheel Emulation Axes (319):       0, 0, 4, 5
        Evdev Wheel Emulation Inertia (320):    10
        Evdev Wheel Emulation Timeout (321):    200
        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？

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

这些xinput 设置是否会反转滚轮方向？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。

【解决方案1】：

尝试运行

$ xinput set-prop 14 311 -1 1 1

将“Evdev 滚动距离”设置为负值以进行垂直移动。
