Comment 20 for bug 476866

I'm not certain how to prove or disprove (a). I looked through all the files attached to this bug report but didn't find anything definitive. I poked around on my own hardware looking at lshal output, various files under /sys/class/input but didn't find something I could suggest checking. Presumably you can check your hardware vendor's data sheets.

Regarding (b), try running this command:

  synclient -m 100

In theory, the fifth column 'f' is the number of fingers seen by the touchpad. Try two fingers, and more, and see if the number changes.
