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.
