If a 2fg scroll motion starts with both fingers in the bottom button area and one finger moves into the main area before the other, we used to send motion events for that finger. Once the second finger moved into the main area the scroll was detected correctly but by then the cursor may have moved out of the intended focus area. We have two transitions where we may start sending motion events: when we move out of the bottom area and when the finger moves by more than 5mm within the button area. In both cases, check for any touches that are in the bottom area and started at the 'same' time as our moving touch. Mark those as 'moved' to release them for gestures so we get the right finger count and axis/gesture events instead of just motion events. 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 so minimize the amount of custom input code the user of libinput need 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

This includes the FAQ and the instructions on reporting bugs.
