[ubuntu] Automatically Configure TrackPoint Sensitivity

Hello guys. I'm using Ubuntu 16.04 with my ThinkPad T520. The default sensitivity of the trackpoint is terrible, but I found out that this command fixes it:

echo 220 | sudo tee /sys/devices/platform/i8042/serio1/serio2/sensitivity

Now, how do I make that execute automatically each time I log in, ideally without having to type my password because of sudo?

Or is there a better way?

Thanks!
