One of the things that bothered me when I switched to Ubuntu was the mouse: while the Mouse settings panel offered options to change the cursor speed, I couldn’t change the scroll wheel settings: I wanted it to be faster, and I wanted it to use Mac OS’ natural scrolling direction.
After a bit of googling, this specific answer helped me get this fixed.
First, you get a list of the different devices linked to your machine, then you check the settings for one of the devices (number 10 in my case), and use
set-prop to customize a specific setting.
-1 got me the natural scrolling back. Victory!
xinput list-props 10
xinput set-prop 10 'Evdev Scrolling Distance' -1 5 5
Now if only I could do something to get all my additional buttons back, that’d be great! :)
