      Use ABS_MT events for the palm detection when supported · a897147b
      Gabriele Mazzotta authored
      Use ABS_MT_TOUCH_MAJOR and ABS_MT_PRESSURE instead of ABS_TOOL_WIDTH
      and ABS_PRESSURE when supported so that the pressure and the width of
      all the fingers is taken into account for the palm detection.
      
      This also fixes the palm detection for those touchpads for which the
      kernel only sends ABS_MT_TOUCH_MAJOR and not ABS_TOOL_WIDTH.

      Limit the movement to 20 mm per event · 41b2312c
      Peter Hutterer authored
      Touchpads are limited by a fixed sampling rate (usually 80Hz). Some finger
      changes may happen too fast for this sampling rate, resulting in two distinct
      event sequences:
      * finger 1 up and finger 2 down in the same EV_SYN frame. Synaptics sees one
        finger down before and after and the changed coordinates
      * finger 1 up and finger 2 down _between_ two EV_SYN frames. Synaptics sees one
        touchpoint move from f1 position to f2 position.
      
      That move causes a large cursor jump. The former could be solved (with
      difficulty) by adding fake EV_SYN handling after releasing touchpoints but
      that won't fix the latter case.
      
      So as a solution for now limit the finger movement to 20mm per event.
      Tests on a T440 and an x220 showed that this is just above what a reasonable
      finger movement would trigger. If a movement is greater than that limit, reset
      it to 0/0.
      
      On devices without resolution, use 0.25 of the touchpad's diagonal instead.

      eventcomm: ensure we're on the same clock as the server · 90d19302
      Peter Hutterer authored
      Default on evdev devices is CLOCK_REALTIME. If that clock falls behind the
      server's CLOCK_MONOTONIC, motion after a clickpad click may be delayed by the
      difference in the clocks.
      
      In detail:
      When the timer func is triggered, GetTimeInMillis() which is CLOCK_MONOTONIC,
      is stored as hwState->millis. The eventcomm backend uses struct
      input_event time (CLOCK_REALTIME).
      
      When we read events from the device, if the evdev time is less than the server
      time, the fix for (#48777) sets the current event time to hwState->millis.
      Until the evdev time overtakes that stored time, all events have the
      hwState->millis time.
      
      If during that time a clickpad triggers a physical click,
      clickpad_click_millis is set to hwState->millis + the ignore-motion timeout.
      Thus, all motion is ignored until the event time overtakes that stored
      time.
      
      The whole issue is further enhanced by us unconditionally setting the timer
      func if we get any events, which is a separate issue anyway.

      Disable GrabEventDevice by default · f1948e08
      Peter Hutterer authored
      This was required when we started supporting hotplugging to avoid duplicate
      events. These days the drawback of not being able to record events in the case
      of a bug is significant.
      
      Check the configuration source on init. If the device was hotplugged through a
      a server config backend, disable the grab. If the device was statically
      configured through an xorg.conf then leave the default grab enabled to avoid
      a duplicate device.
