Tuning the sensitivity of the Lenovo TrackPoint on Ubuntu
I have recently installed Ubuntu Budgie on my Lenovo ThinkPad T420. So far, the experience has been great. However, a crucial part of the IBM/Lenovo experience is the TrackPoint, the red nub at the center of the keyboard. Love it or hate it, for many people it is the main reason to buy a ThinkPad. Here is how I configure it to run on Ubuntu. This was tested with Ubuntu 18.04 LTS.
Setting up persistent sensitivity settings for the TrackPoint
- First, install
sysfsutils
:
1
sudo apt-get install sysfsutils
- Second, edit the
/etc/sysfs.conf
. Add the following lines at the end.

#tweak trackpoint
devices/platform/i8042/serio1/serio2/sensitivity = 215
devices/platform/i8042/serio1/serio2/rate = 280
devices/platform/i8042/serio1/serio2/speed = 150
devices/platform/i8042/serio1/serio2/inertia = 1
These are my personal settings so far. Play with the values until you find the ones that suit your usage.
- Try out different configurations
Adjust the values and run sudo service sysfsutils restart
to try out the new values until you get it just right for yourself.
