I finally found a working solution:
1. Find the device path of your trackpoint
Run the following in a gnome-terminal (can be opened with Ctrl+Alt+t):
find /sys/devices/platform/i8042 -name name | xargs grep -Fl TrackPoint | sed 's/\/input\/input[0-9]*\/name$//'
It will return something like
change to whatever it returns for you in the following step.
2. Create a new upstart-job
Still in the terminal type:
sudo gedit /etc/init/trackpoint.conf
A text editor will pop up. Paste the following code in it:
start on virtual-filesystems
while [ ! -f $TPDIR/sensitivity ]; do
echo -n 200 > $TPDIR/sensitivity
echo -n 150 > $TPDIR/speed
echo -n 1 > $TPDIR/press_to_select
Don' forget to edit the second line if needed (see step 1).
You can edit the numbers in line eight and nine (representing sensitivity and speed) to whatever you prefer. Both can be set in a range from 0 to 255. Leaving them at 200 and 150 works good for me.
Save and exit.
