how to install driver for middle button clickpad scrolling

rated 0 times [ 2] [ 0] / answers: 1 / hits: 5706 / 2 Years ago, fri, may 27, 2022, 9:13:58

I want to use this

as this:

Specifically, I'm trying to enable scroll wheel emulation using the TrackPoint when the middle button 2 of the clickpad is pressed.

I've examined the xev output when a TrackPoint is used for scrolling with dedicated buttons (button 4 is recognised as a scroll up operation and button 5 is recognised as a scroll down operation) but the behaviour is different when using the clickpad buttons (button 2 is recognised in isolation). It appears that a modified driver is needed in order to enable scrolling using the middle button of the clickpad.

Such a driver appears to be available here:

https://aur.archlinux.org/packages/xf86-input-evdev-trackpoint/

How could this driver be installed in Ubuntu?

As suggested by mikewhatever, the driver for Arch created by Taegil Bae (esrevinu) can be packaged for Ubuntu and installed using a procedure described by dalcde. The procedure was updated by faf0, since a tar.gz file from the procedure by dalcde became unavailable in December 2015. The procedure is as follows:

#!/bin/bash



sudo apt-get install git

sudo apt-get build-dep xserver-xorg-input-evdev xserver-xorg-input-synaptics



mkdir tmp-trackpoint

cd tmp-trackpoint



git clone https://aur.archlinux.org/xf86-input-evdev-trackpoint.git

git clone git://git.debian.org/git/pkg-xorg/driver/xserver-xorg-input-evdev

git clone git://git.debian.org/git/pkg-xorg/driver/xserver-xorg-input-synaptics



mv xf86-input-evdev-trackpoint arch

mv xserver-xorg-input-evdev evdev

mv xserver-xorg-input-synaptics synaptics



cp synaptics/src/{eventcomm.c,eventcomm.h,properties.c,synaptics.c,synapticsstr.h,synproto.c,synproto.h} evdev/src

cp synaptics/include/synaptics-properties.h evdev/src

cp arch/*.patch evdev



cd evdev

patch -p1 -i 0001-implement-trackpoint-wheel-emulation.patch

patch -p1 -i 0004-disable-clickpad_guess_clickfingers.patch

patch -p1 -i 0006-add-synatics-files-into-Makefile.am.patch



dpkg-buildpackage -d



cd ..

sudo dpkg -i xserver-xorg-input-evdev_*.deb

sudo apt-get remove xserver-xorg-input-synaptics



sudo mkdir /etc/X11/xorg.conf.d/

sudo cp arch/90-evdev-trackpoint.conf /etc/X11/xorg.conf.d

The procedure above works on Ubuntu 14.04.
