Maybe it is caused by unity or upper layer software, could you reproduce
it every time? or it just happened one time?

Your dmesg output shows some other failure about acpi video:

[ 17.488435] [Firmware Bug]: Duplicate ACPI video bus devices for
the same VGA controller, please try module parameter
"video.allow_duplicates=1"if the current driver doesn't work.

But this is nothing to do with touchpad driver.
