Comment 54 for bug 1506817

Dear Pascal
This is very strange. I'm going now since 12/31/16, and now its 1/3/17, thus somewhere between 3-4 days.
I have tested it, and have not seen any problem.

You suggest removing the trackpad in the bios. That worked for me in the past (limited success), but with my present BIOS (the latest, I can give you the number if you request), the OS ignores the BIOS setting.
Here is the test of that:
1) deselect the trackpad in the bios
2) reboot
3) Before you log in, test if the trackpad is active. I find that it is.
4) login, and with the "system settings/mouse/touchpad" I now see not reference to the touchpad in that
screen.

Conclusion: After removeing the touchpad via the BIOS, it was still working after a reboot. And, there was
no way to turn it on or off from "system settings"

Using my Dell latitude, the behaviour is quite different. So the above is restricted to the X250.
