Trackpoint and Clickpad: enable buttons and scroll (Lenovo T440s) [closed]
I just got a Lenovo T440s which is equiped with synaptics touchpad. By default there's no middle button and right button is at right bottom corner of touchpad. I'm used to the combination of trackpointer+left/middle/right buttons and I REALLY miss that on my new model. It generates some noise every time I press the button, since the button is also a part of touchpad.
What I did so far is:
- increase Hysteresis of touchpad to a very high value, which literally disabled navigation
- Enable Clickpad mode, which provides functions of middle/right button
- Define middle/right button area as expected on touchpad
But the problem is that middle button is not mapped to trackpointer. They seem to be two independent devices on this model. I'm wondering how I can connect the event triggered by middle button to the wheel emulation button of trackpointer.
Here's the output of my xinput properties: Xinput list:

I googled around and checked lots of threads and failed to find a proper solution. But when I use windows 8.1 on this model and install synaptics touchpad driver, it's working perfectly. So another proposal is to port that driver to linux.
Any help would be appreciated thanks in advance!

If I did understand you correctly, then this post by Peter Hutterer might be of help to you. T440 trackpoint buttons support seems to be a work in progress and is currently more kind of a workaround.
He illustrates with ASCII-art that they can't configure the touchpad like on Windows:
+----------------------------+
| LLLLLLLLLL MMMMM RRRRRRRRR |
| |
| |
| |
| |
| |
| |
| LLLLLLLL RRRRRRRR |
+----------------------------+
and have to configure the touchpad buttons rather like this:
+----------------------------+
| LLLLLLLLLL MMMMM RRRRRRRRR |
| LLLLLLLLLL MMMMM RRRRRRRRR |
| LLLLLLLLLL MMMMM RRRRRRRRR |
| LLLLLLLLLL MMMMM RRRRRRRRR |
| LLLLLLLLLL MMMMM RRRRRRRRR |
| LLLLLLLLLL MMMMM RRRRRRRRR |
| LLLLLLLLLL MMMMM RRRRRRRRR |
| LLLLLLLLLL MMMMM RRRRRRRRR |
| LLLLLLLLLL MMMMM RRRRRRRRR |
+----------------------------+
Statement and current workaround:
I'm working on a solution for the proper config, but for now you'll have to be content with this.
The easiest approach for local configuration is a new InputClass section in the form:
Section "InputClass" Identifier "t440 top buttons" MatchDriver "synaptics" # right btn|middle btn Option "SoftButtonAreas" "60% 0 0 0 40% 60% 0 0" EndSectionDrop that into
/etc/X11/xorg.conf.d/99-t440-synaptics.confand you're good to go.
