Right now for touch arbitration to work, we require the device group to be the same (i.e. they're hanging off the same physical bus). That's not always the case and statistically we have a lot more devices that have a built-in tablet + touchscreen than we have Intuos-like external tablets. So let's default to the more common case - enabling arbitration with the first touchscreen/external touchpad we find. If a subsequent device is "better", swap it out. Right now, the only heuristic we have here is the device group check but in the future we could get more precise. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> |

libinput
libinput is a library that provides a full input stack for display servers and other applications that need to handle input devices provided by the kernel.
libinput provides device detection, event handling and abstraction to minimize the amount of custom input code the user of libinput needs to provide the common set of functionality that users expect. Input event processing includes scaling touch coordinates, generating relative pointer events from touchpads, pointer acceleration, etc.
User documentation
Documentation explaining features available in libinput is available here.
This includes the FAQ and the instructions on reporting bugs.
