I plugged in a Logitech iFeel usb wheel mouse to make sure that this setting would work with this logitech mouse.
Here is the corresponding entry in /etc/X11/XF86config-4 for this setting:
Code:
Section "InputDevice"
Identifier "Mouse1"
Driver "mouse"
Option "Protocol" "ExplorerPS/2"
Option "Device" "/dev/mouse"
Option "ZAxisMapping" "6 7"
EndSection
