I've already posted my solution for this in Bug #1070207 which seems to be a duplicate of this bug.
No need to recompile the kernel, just use DKMS :) Can confirm that this bug still exists on Lenovo L430/L530 with Ubuntu 14.10 https://drive.google.com/file/d/0ByR4ekc5XtmPTWxQUkdZWkt2YXM/view?usp=sharing The link points to a dkms tar.gz with a backported elantech driver from the current 3.18 kernel (that has the the fix for the issue included). I call it "backported" as it was _slightly_ changed. __set_bit(INPUT_PROP_POINTING_STICK, tp_dev->propbit); had to be commented out in elantech.c as kernel 3.16 doesn't support the INPUT_PROP_POINTING_STICK bit. Apart from elantech.c and elantech.h everything else was coppied from the latest 3.16 ubuntu kernel sources. This has been tested with ubuntu 14.10, *should* be compatible with ubuntu 14.04 (not tested) TL;DR: Download https://drive.google.com/file/d/0ByR4ekc5XtmPTWxQUkdZWkt2YXM/view?usp=sharing sudo apt-get install dkms sudo dkms ldtarball psmouse-elantech-3-18.tar.gz sudo dkms install -m psmouse -v elantech-3-18 sudo rmmod psmouse sudo modprobe psmouse -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/967399 Title: [11.10] Elantech trackpoint does not work Lenovo Status in linux package in Ubuntu: In Progress Status in linux source package in Precise: Fix Released Bug description: Title: trackpoint does not function Summary: trackpoint does not function Steps: 1. log into desktop 2. use trackpoint and trackpoint buttons Expected results: laptop responds to trackpoint and trackpoint buttons being pressed Actual results: nothing happens Manufacturer: LENOVO WORKAROUND: sudo modprobe proto=exps enables the trackpoint and touchpad, but user will lose multi-touch functionality.
