Setting the Thinkpad Trackpoint Sensitivity on Linux
Note: This was tested on my Thinkpad T440s on Debian 10 Buster. Depending on your model of Thinkpad, the file path in
/sys may be different. Use
find to find a file called
sensitivity and test with that.
Changing the Sensitivity on the Fly
This is fairly easy to do. You just have to
echo a value into
echo 120 | sudo tee /sys/devices/rmi4-00/rmi4-00.fn03/serio2/sensitivity
Systemd Service File
To have this work on startup, a systemd service file is probably the easiest way I know of to have that command be executed since it needs to be run as
root. Sometimes, my thinkpad will boot with the path being
/sys/devices/platform/i8042/serio1/serio2/sensitivity which I have accounted for in the script below.
First, create a script with the following content and place this script wherever you think is appropriate such as
~/.local/bin. I put mine in
#!/bin/sh -eu echo 120 > /sys/devices/rmi4-00/rmi4-00.fn03/serio2/sensitivity || echo 120 > /sys/devices/platform/i8042/serio1/serio2/sensitivity echo "Set trackpoint sensitivity." exit 0
Make sure that this script is executable with
chmod +x <path_to_script>.
Then, make a service file
[Unit] Description=Sets the Thinkpad Trackpoint Sensitivity [Service] Type=simple User=root ExecStart=<full_path_to_script> [Install] WantedBy=default.target
<full_path_to_script> must be the full path, not a relative path (i.e. it must start with
After creating the service file enable it:
systemctl daemon-reload systemctl enable trackpoint.service
Now, when you reboot, you should have the trackpoint sensitivity automatically set.
