I'm running the latest kubuntu with plasma 5 on a t440s laptop. The trackpoint is very slow and there's no option to increase the sensitivity under the system input settings. The same laptop is running elementary os freya and I can adjust this via xinput. On kubuntu changing the xinput values has no effect.

Any idea how I can adjust this?

    Well, it's working now with xinput. Apparently I need to set values different than the ones I have on elementary OS. – black Oct 16 '15 at 07:40

The change the sensitivity (and speed, etc.) permanently, you can create an udev rule.

E.g. create a file 10-trackpoint.rules in /etc/udev/rules.d/ with the following contents:

SUBSYSTEM=="serio", DRIVERS=="psmouse", WAIT_FOR="/sys/devices/platform/i8042/serio1/serio2/sensitivity", ATTR{sensitivity}="220",  ATTR{speed}="190", ATTR{inertia}="6", ATTR{press_to_select}="0"

This method was tested on Ubuntu 14.04 up to 15.04.

For further explanations check on the Archwiki and Thinkwiki and look for "sensitivity".

Update for Ubuntu 15.10

The above rule does not trigger properly on Ubuntu 15.10. Instead use:

ACTION=="add", SUBSYSTEM=="input", ATTR{name}=="TPPS/2 IBM TrackPoint", ATTR{device/sensitivity}="220", ATTR{device/speed}="190", ATTR{device/inertia}="6", ATTR{device/press_to_select}="0"
