[SOLVED] Wheel emulation with clickpad

I recently got a new Lenovo T431s and I'm trying to get wheel emulation to work for the trackpoint. Unlike other ThinkPad models, this has a clickpad - a trackpad with only one physical button, which is the trackpad itself. I was able to configure the synaptics driver to detect soft buttons for middle and right clicks on the top edge of the trackpad. I would like to use this middle soft button for wheel emulation with the trackpoint through evdev. However, this doesn't work and I assume it's because evdev only sees the raw input from the clickpad and not the button events interpreted/created by synaptics. In other words, both evdev and synaptics operate at the same level (on the same input) and it's impossible to put evdev above synaptics so that it will see middle clicks. Can anyone confirm that my understanding is correct? And if you know anything about X, can you say whether it's feasible to modify the drivers (or X) to get the desired effects?

Re: [SOLVED] Wheel emulation with clickpad

With my Thinkpad Edge (which has the same trackpad) it worked out of the box, I use KDE if this changes something.

Check out this thread and the linked AUR package: https://bbs.archlinux.org/viewtopic.php?pid=1359126. I haven't read the thread - just installed the patched package and it worked perfect.
