Scripts for Ubuntu 14.04 and 16.04 (or similar distributions) on Lenovo ThinkPads (tested on X1 Carbon 2nd Generation and reported to work on X240).

Script Descriptions

Touchpad Scripts

The touchpad scripts allow for emulating three trackpad buttons which do not exist on many 2014 series ThinkPads (see http://askubuntu.com/q/443642 for pictures). Moreover, the touchpad scripts disable movements for part of the touchpad (only possible with trackpad-fix.sh) or the complete touchpad (possible with trackpad-fix.sh or libinput-disable-touchpad-movements.sh) to prevent accidental pointer movements. Disabling the touchpad mouse pointer is useful if the TrackPoint is supposed to be the only mouse pointer device.

• On Ubuntu 14.04, run cd 14.04/ && ./trackpad-fix.sh.
• On Ubuntu 16.04, please install the package xserver-xorg-input-libinput and then execute cd 16.04/ && ./libinput-disable-touchpad-movements.sh. Script libinput-disable-touchpad-movements.sh will fetch the sources of libinput, patch them, build a .deb package, and install it. Make sure to have the Ubuntu source repositories enabled. The script will also install some packages that are needed to build the package from source. If the script fails due to a missing package dependency, install the dependency, remove the folder tmp-libinput, and run libinput-disable-touchpad-movements.sh again.

TrackPoint Acceleration

To accelerate your TrackPoint, consider calling one of the following scripts from ~/.xprofile.

• 14.04/trackpoint-fast.sh: For Ubuntu 14.04.
• 16.04/trackpoint-fast-libinput.sh: For Ubuntu 16.04. Please install the package xserver-xorg-input-libinput.

Uninstallation

• Ubuntu 14.04: To replace the patched touchpad driver with the original Ubuntu version, run the following commands:

sudo apt-get install xserver-xorg-input-synaptics
sudo apt-get install --reinstall xserver-xorg-input-evdev
sudo rm /etc/X11/xorg.conf.d/90-evdev-trackpoint.conf

• Ubuntu 16.04: To replace the patched touchpad driver with the original Ubuntu version, run sudo apt-get install --reinstall libinput10.
• Ubuntu 14.04 and Ubuntu 16.04: Remove the calls of the TrackPoint acceleration scripts from ~/.xprofile.
