In KDE, try "Settings-->System Settings-->Hardware-->Input Devices-->Mouse-->Advanced-->Mouse Wheel Scrolls by." That's where the setting resides in Slackware Current's KDE.

I must say, it is buried many fathoms deep.

I have tried this few days ago and doesn't work. I have even find a kde bug on this matter. I have tried solution with imwheel and it works. But the problem is that with imwheel i can't scroll unfocused windows and the other problem is that when i scroll in libreoffice the blinking cursor also moves with scrolling. Any idea?
