I have a laptop (HP Elitebook 8540w) that has touchpad and a pointstick.
The buttons(3 below the touchpad for when using the touchpad, 3 above
for when using the pointstick) are part of the touchpad device. The
pointstick device has no buttons. While X.org automatically configures
things properly so everthing works well, there is one problem. I cannot
find a way to configure the middle button to act as a scroll button for the point stick. How would I go about
configuring the middle button(belonging to the touchpad) to do scrolling when the pointstick is moved up/down?
