How do I disable the touchscreen on my Dell Precision 5560?

Question

Summarize the problem
I don't like my touchscreen, and attempts at disabling it via xinput have proved fruitless.

Provide details and any research
I also tried this method, but even after adding Option "Ignore" "on" to every single section that had "touchscreen" in the name, the touchscreen still worked.

When appropriate, describe what you’ve tried
As mentioned, neither xinput nor editing the configuration files worked.

Answer 1

It turns out the best solution was quite simple! I was able to turn it off in the Dell BIOS. I would encourage users of any brand of laptop to attempt to try it that way first. Zero hackiness!
