Description Peter Hutterer 2016-07-13 01:02:48 UTC

Example: the touchpad in bug #96875 is only 41mm high, minus the 7mm edge scroll zone makes for a touchpad surface area that's too small to use.

In this case we should just disable the horizontal scroll area, it's not that important anyway and for the few cases where it's needed we just have to tell users to use the scroll bars instead.

Addendum: on clickpads we have an area reserved for software buttons anyway so we can keep it enabled. This affects the Lenovo *20 and *30 series touchpads.

When these came out clickfinger wasn't much of a thing yet so they're all designed to work with software buttons.
