Ubuntu Desktop 鼠标滚轮滚动方向

由于使用 OSX 习惯了, 所以希望 Ubuntu Desktop 使用中鼠标也行是自然方向滚动,以下是实现方法:

14.04 - Mouse wheel scrolls in reversed direction - Ask Ubuntu

查看输入设备列表:

~$ xinput list

输出类似:

⎡ Virtual core pointer                          id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ USB OPTICAL MOUSE                         id=12   [slave  pointer  (2)]
⎜   ↳ 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)]↳ Power Button                              id=8    [slave  keyboard (3)]↳ Sleep Button                              id=9    [slave  keyboard (3)]↳ LiteOn Lenovo Calliope USB Keyboard       id=10   [slave  keyboard (3)]↳ LiteOn Lenovo Calliope USB Keyboard       id=11   [slave  keyboard (3)]↳ USB OPTICAL MOUSE                         id=13   [slave  keyboard (3)]

其中 USB OPTICAL MOUSE 这个就是 usb 鼠标, 根据我的经验,需要修改的是第二个(id=14 这个).

~$ xinput list-props 14

输出:

注意 libinput Natural Scrolling Enabled (395) 这个的值默认是0, 修改为 1, 鼠标的滚轮滚动就是自然方向滚动了:

xinput set-prop 14 395 1

如果报错 Unable to connect to X server, 运行以下语句即可

export DISPLAY=:0.0
