good, I'm glad someone else is seeing this problem. Here is a test I would like you to try:
boot up into the BIOS, and turn off only the trackpad. Leave the pointing (red button) on. Then boot up into linux, and BEFORE you login in, see if the trackpad responds to the touch. On my X250, it does, and that is a problem with the BIOS not working properly. I have three thinkpads with a trackpad, and the with the two that work, I can turn off the trackpad, and the trackpad is off before I login in. This may not be the only issue with this bug, but it aggravates it. If the trackpad could be turned off in the BIOS (as it should be) then that would be a work-around. I am able to use the X250 only if I use a USB (external) mouse. The trackpad is too buggy to use.

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.
