I'm using default Ubuntu on a very cheap Lenovo Ideapad and it passes this test. Additionally, the touchpad works almost as well as my Mac, other than one significant annoyance: double finger right click is difficult, because it has a tendency to scroll the window as I try to press down, meaning I miss the thing I'm trying to right click.
The touchpad drivers and input stack have come a very long way in Linux, if (BIG IF) you're running well supported hardware.
