Comment 15 for bug 923749

Rick,

The drivers are the primary reason this isn't working for some people. Some touchpads are scaling inputs incorrectly, resulting in very low velocity pressures. This should not prevent it from working for these people, but it does make revealing take a bit more effort than intended. I have not seen a completely unworkable setup yet. The slider merely helps people who have misbehaving hardware deal with the faulty drivers.

Ideally, the correct thing to do would be to ensure that all touchpads react the same way on all machines.
