Actual behavior: Whenever I use the trackpoint, a (random) button is pressed, most of the time button 2 (middleclick). The button is only rarely release, it usually stays "pressed". I then can continue to use the trackpoint with the button(s) pressed, they are not pressed again. Example: motion a[0]=226 a[1]=855 button press 2 motion a[0]=226 a[1]=857 motion a[0]=226 a[1]=858 ... The button(s) are released again when I actually press a mouse button. When I e.g. press mouse button 1 (leftclick), the following happens: button press 1 button release 2 button release 1 EDIT: Although I'm using Kubuntu, the same bug appears when I boot Ubuntu. The bug does not appear on Windows.
