ThinkPad trackpoint: adjust speed and sensitivity

[rybnik]

I just switched to Kubuntu Vivid after previously running openSUSE 13.1 and Kubuntu Precise.

I have a ThinkPad with a keyboard and touchpad that look like this.

In my previous operating systems, I was able to change the speed and sensitivity of the trackpoint (the small red ball above the "B" key) with the following commands, as documented here.

echo -n 100 > /sys/devices/platform/i8042/serio1/serio2/speed
# default is 97, interval of 0 to 255
echo -n 200 > /sys/devices/platform/i8042/serio1/serio2/sensitivity
# default is 128, interval of 0 to 255

However, neither of the above commands work in Kubuntu Vivid.

I initially thought that perhaps I was operating on the wrong directory, and that the "speed" and "sensitivity" files might instead be in something besides serio1/serio2. But then, using catfish, I searched for "speed" in /sys/devices/platform/i8042, and it didn't find anything. A search for "sensitivity" in /sys/devices/platform/i8042 didn't return any results either.

So... does anyone know how to configure a trackpoint in Kubuntu Vivid?

Thanks!

I think it was preferable to have separate settings for speed and sensitivity, but the controller you described is sufficient.
