Hi Juanito! Now one friend told that he bought on ebay "usable touchpad" to replace default one on Thinkpad T440 (that one without physical buttons). One which he bought is ALPS V7 and it works fine on that T440. And also trackpoint with buttons are working. He told that first time he had connected & assembled it, trackpoint have not worked. And it was because he forgot to connect something in trackpoint. So he need to disassemble it again, check, connect and assemble laptop back. So now I have confirmed that replaced ALPS V7 is working fine at least on some T440 laptops. So if you wrote that buttons (above touchpad) are working, but trackpoint not, maybe you have same problem? Forgot to properly connect trackpoint? If it is really disconnected, then ALPS touchpad is not able to detect it and therefore tell kernel that trackpoint is not available. -- Pali Rohár pali.rohar@xxxxxxxxx
