Those touchpads presents an actual lower resolution that what is advertised. We see some jumps from the cursor due to the big steps in X and Y when we are receiving data. For instance, we receive: E: 13.471932 0003 0000 16366 # EV_ABS / ABS_X 16366 E: 13.471932 0003 0001 9591 # EV_ABS / ABS_Y 9591 E: 13.471932 0000 0000 0000 # ------------ SYN_REPORT (0) ---------- E: 13.479924 0003 0000 16316 # EV_ABS / ABS_X 16316 E: 13.479924 0003 0001 9491 # EV_ABS / ABS_Y 9491 E: 13.479924 0000 0000 0000 # ------------ SYN_REPORT (0) ---------- E: 13.487939 0003 0000 16271 # EV_ABS / ABS_X 16271 E: 13.487939 0003 0001 9403 # EV_ABS / ABS_Y 9403 E: 13.487939 0000 0000 0000 # ------------ SYN_REPORT (0) ---------- -> jumps of ~50 in X in each report, and ~100 for Y. Apply a factor to minimize those jumps at low speed, and try keeping the same feeling as regular touchpads at high speed. It still feels slower but it is usable at least Signed-off-by: Benjamin Tissoires <benjamin.tissoires@gmail.com> Reviewed-by: Peter Hutterer <peter.hutterer@who-t.net> Tested-by: Vasily Khoruzhick <anarsoul@gmail.com> Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> |

/*!@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, the Wayland reference compositor. The source code of libinput can be found at: http://cgit.freedesktop.org/wayland/libinput For more information, visit: http://www.freedesktop.org/wiki/Software/libinput/ Bugs can be filed in the libinput component of Wayland: https://bugs.freedesktop.org/enter_bug.cgi?product=Wayland&component=libinput Online API documentation: http://wayland.freedesktop.org/libinput/doc/latest/modules.html */
