It is not restricted to this model. Even the better-quality X240, which I use at work and sometimes with FreeBSD, does have the same issue. The much cheaper, more plastique version of that touchpad is in builtin in E540, L540 and some others and the fun part is: someone can provoke ghostmovement by putting hot objects in the vicinity of the touchpad. Typing, for instance, a text for a report, with hands layed down on the chassis, turns into a horror: while typing, suddenly you get close enough to the touch thing and suddenly the carret jumps randomly into another portion of the text. That happens in editors running in X11/windowmaker or any other WM I tried so far. As polytropon stated earlier, just disabling PS/2 was one of my first thoughts, so I disabled support in the kernel. But since the Lenovo's keyboard is also(!) PS/2 (not USB), I lost keyboard, too. A while ago, I also tried some recommendations I digged from the net - without success. I think I still mess up with the HAL support and the weird, mostly not-well documented way to enable/disable/configure devices, device support in its XML synatax. By the way, I try to avoid HAL. This may also cause some problems when trying suggestions. By the way - some companies around I have contact, too, also complained massiveley on that crappy touchpad - it goes up even to the high-class notebooks from Lenovo. The recently issued lines do not have that crap anymore: X250, E550, L550, W550 have a nice touchpad with the buttons separeted again and very accurate function. But: on larger notebooks, the warm hands laying down on the touchpad do the same ghostmovement as described above - but a little less inflicting. > > On 9/28/15, O.
