My ThinkPad is a very unpleasant feature — the button under the touchpad stick out so that lounging with a laptop on the couch, constantly hit them in the folds of clothes or just the belly. The touchpad I do not need, Trackpoint much easier, but I can't seem to disable it under Ubuntu. In Windows this is normally done through settings, and in Ubuntu, though you can disable in System Settings-Pointing Devices, but in a minute he, the infection, spontaneously turn on. I googled here this line to add in .profile:
xinput set-button-map "SynPS/2 Synaptics TouchPad" 0 0 0
This helps partly after sleep or hibernate the damn buttons work again. In addition, even when they are disabled when the buttons are squeezed for a few seconds, start to act funny buttons of the TrackPoint, as if the left changes to the average. I completely cut out the touchpad from the system???
