As you can see, they are almost equal, but the problem is that the
features are not the same:
- When the touchpad (the keyboard with touchpad) is attached, I can
use 2 fingers to emulate the right click, scrolling, etc. I don't
understand correctly why I can do that when the "Scroll Methods
Available" does not include it.
- When it's detached I can't use the 2 fingers. Trying them on `xev`
or `evtest` doesn't produce any output.
