The average human hand has four fingers but only one thumb, i.e. the chance of a fake finger being close to the top-most touch is higher than to whatever the first touch was (which may be a thumb at the bottom of the touchpad). So search for the top-most real touch and copy its position into the fake touches. This also fixes another bug with the previous code - the first slot may not be active but we still used its position for the fake touches. Whether that was really triggerable is questionable though. The test is only run for the T440 touchpad - we know it's big enough to enable thumb detection and that way we don't have to double-check in the how big the touchpad is, etc. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> Reviewed-by: Hans de Goede <hdegoede@redhat.com> |

/*!@mainpage libinput ======== libinput is a library that handles input devices for display servers and other applications that need to directly deal with input devices. It provides device detection, device handling, input device event processing 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 pointer events from touchpads, pointer acceleration, etc. libinput originates from [weston](http://cgit.freedesktop.org/wayland/weston/), the Wayland reference compositor. Architecture ------------ libinput is not used directly by applications, rather it is used by the xf86-input-libinput X.Org driver or wayland compositors. The typical software stack for a system running Wayland is: @dotfile libinput-stack-wayland.gv Where the Wayland compositor may be Weston, mutter, KWin, etc. Note that Wayland encourages the use of toolkits, so the Wayland client (your application) does not usually talk directly to the compositor but rather employs a toolkit (e.g. GTK) to do so. The simplified software stack for a system running X.Org is: @dotfile libinput-stack-xorg.gv Again, on a modern system the application does not usually talk directly to the X server using Xlib but rather employs a toolkit to do so. Source code ----------- The source code of libinput can be found at: http://cgit.freedesktop.org/wayland/libinput For a list of current and past releases visit: http://www.freedesktop.org/wiki/Software/libinput/ Reporting Bugs -------------- Bugs can be filed in the libinput component of Wayland: https://bugs.freedesktop.org/enter_bug.cgi?product=Wayland&component=libinput Where possible, please provide an [evemu](http://www.freedesktop.org/wiki/Evemu/) recording of the input device and/or the event sequence in question.
