Here is a summary of the two commands from comment #32 (above) for the
X250.

1) The driver is different between the X201 and the X250
1.8.2-1ubuntu1  <-- X201   (Working)
1.8.2-1ubuntu3  <-- X250  (Not working)

2) For the X201 the apt-cache results different (none installed), while for the X250 the driver is installed.

Title:
  left TPP/2 IBM TrackPoint "sticks on" randomly (X250 15.04)

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I have reported the details of this problem at
  https://answers.launchpad.net/ubuntu-certification/+question/272142

  As summarized on that question:

  X250 analysis:
   I used the command on the X250
    evtest /dev/input/event15 | grep EV_KEY

   I can see the bug, as follows:

  I click on button 1 (left) over and over. When I push the button down,
  I see it register as 1,
  and when I let go of the key, it registers as a 0.

  The bug is that every now and then (once every 20 clicks), when I let go
  of the left mouse button (BIN_LEFT), it does not return to state 0 (it stays in state 1).

  This is highly random, but cant be triggered more often, by dragging a
  window, which I do with BIN_LEFT.

  I am using a brand new X250, purchased in late July 2015. The system was returned 3 times to IBM repair as I assumed
  this was a hardware error. Now with the above, it seems clear that this is a software issue.
