I'm not exactly sure why the point is not clear. You can make the same argument for normal mouse cursor movement, where mouse cursor acceleration is a pretty standard thing. And I think it makes even more sense for mouse wheel scrolling than it does for mouse cursor movement. In all cases, you want to be able to make precise movements, as precise as what the application allows (pixel based or line based but e.g. for scrolling a list, I think a nicer experience is pixel based in all cases). So this requires that the minimum possible scroll/movement speed greater zero is as low as possible (e.g. 1 pixel). Also, you would want to make the movement/scrolling as fast as possible. For mouse cursor movement, this might be less of a problem because the screen is usually of finite size and usually not so big anyway. That is why I think it is even more important for scrolling than for cursor movement. The scroll area can usually be much larger (e.g. a whole book) or even be infinite and you might want to skip over huge parts at once. By acceleration, you solve this nicely as this dynamically adapts the speed. It will be slow if you move slowly but it can be as fast as you want. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/619403 Title: [KDE] no option for mouse wheel acceleration Status in X.Org X server: Unknown Status in xorg-server package in Ubuntu: Confirmed Bug description: I am very used to mouse wheel acceleration but I haven't found any setting for it in the KDE settings.
