I cannot set the right mouse wheel scroll

Question

I have Ubuntu 20.10. I have problems with my mouse wheel because the scrolling has the reversed direction. There is this question, which I read. However this is not a dup because after having done all the instructions my wheel has the desired behavior but after restarting my laptop I reobtain the "wrong" scrolling. Here are all the passages:

On the terminal:

~$ xinput list

I obtain the following list:

⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ OM                                        id=11   [slave  pointer  (2)]

⎣ Virtual core keyboard                     id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]

    ↳ Power Button                              id=7    [slave  keyboard (3)]
    ↳ Video Bus                                 id=8    [slave  keyboard (3)]
    ↳ Power Button                              id=9    [slave  keyboard (3)]
    ↳ Sleep Button                              id=10   [slave  keyboard (3)]
    ↳ VGA WebCam: VGA WebCam                    id=12   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard              id=15   [slave  keyboard (3)]
    ↳ Acer WMI hotkeys                          id=16   [slave  keyboard (3)]

after that:

~$ xinput list-props 11

I obtain:

    libinput Drag Lock Buttons (334):   <no items>
    libinput Horizontal Scroll Enabled (335):   1

In fact the natural scrolling is enabled because libinput Natural Scrolling Enabled (316): 1. Inserting xinput set-prop 11 316 0 it scrolls correctly but it doesn't last long.

Any idea?

Answer 1

Setting xinput set-prop 11 316 0 is not enough since it gives a temporary variation. It seems obvious but in the settings, under mouse and touchpad one should disable Natural scrolling. This gives a permanent change.
