Comment 61 for bug 124440

1. I would advice people to switch to KDE from Gnome. It has proper mouse settings and much more.

2. I don't know if it helps for somebody, but I use mouse scroll emulation when the right mouse button is clicked down then moving the mouse up and down scrolls. -> I can more dinamically/quickly/accurately use on my laptop.

It is a system wide solution, set up once, restart the computer and enjoy in every app. It does not matter if it is Gnome or KDE. Create a file /etc/X11/xorg.conf.d/10-evdev.conf with the content:

Section "InputClass"
        Identifier "evdev pointer catchall"
        MatchIsPointer "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
        Option "EmulateWheel" "true"
        Option "EmulateWheelButton" "3"
EndSection

I originally used this tweek because my laptop does not have a touchpad, but I pleased to use with my Bluetooth/USB mouses for the same machine, it is a much better experience for me.
