I move the arrow of touchpad speed bar to the left. Also, I tweak dconf editor's touchpad setting motion-acceleration, motion-threshold, etc.. and it didn't work. After all, if I change scroll-method from two-finger-scrolling to edge-scrolling, it didn't change at all, also set touchpad-enable to off, and it didn't change too. Those are answers posted on askubuntu. So what are these setting? Is it any meaningful functionality built in Ubuntu? And is it feasible to change touchpad scrolling speed?
I use MacBook Pro trackpad, and I want to set the speed as smoothly and user-friendly as OS X.
Thanks.
