evdev: if a device's rotation is around 180 degrees, flip the wheel

2023-04-27T03:15:14+00:00

For a device used upside-down, make sure the wheels correspond to the
new physical directions. There's a grace range of 20 degrees either way
since that seems like it makes sense.

For 90 degree rotation (or 270 degree) the wheel is left as-is, the
heuristics to guess what angle we want in this case is not clear enough.

Disregard touchless clicks on flaky devices

2023-04-11T02:00:52+00:00

Some touchpads, notably those on the Dell XPS 15 9500, are prone to registering
touchpad clicks when the case is sufficiently flexed. Ignore these by
disregarding any clicks that are registered without touchpad touch.

touchpad: Disable edge palm detection Apple touchpads

2023-04-06T07:34:20+00:00

This hurts more than it helps, and users complain of dead trackpad
edges. Apple touchpads have fairly sophisticated internal palm rejection
algorithms going back many years, so let's just disable this one on
everything Apple.

Related to: #433 (need to figure out what other hardware may need this)

evdev: Enable natural scrolling by default on Apple

2023-04-06T06:30:14+00:00

As suggested by the comment itself. I think most users expect this.

tablet: always enable touch arbitration with touchscreens/ext. touchpads

2023-03-30T05:53:23+00:00

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.

fallback: don't double-map if any left-handed buttons are down

2023-03-29T06:37:24+00:00

The key_count array for buttons records the logical button sent to the
client - for left-handed configurations that means a BTN_LEFT is
recorded as BTN_RIGHT.

When the device is suspended and we are releasing all keys we must thus
release the button code as-is without trying to map it again.

Fixes #881

doc: document libinput_device_tablet_pad_get_* error case

2023-03-25T18:33:05+00:00

Like in libinput_device_switch_has_switch()'s documentation, document
the error case in libinput_device_tablet_pad_get_num_buttons(),
libinput_device_tablet_pad_get_num_rings() and
libinput_device_tablet_pad_get_num_strips().

touchpad: rm dead tp_palm_tap_is_palm

2023-03-23T00:22:25+00:00

This was added in 39f11253471500cd380c8977b8cbe0683abe6b1d
(https://bugs.freedesktop.org/show_bug.cgi?id=89625)

Later, a more sophisticated palm detection was implemented in
46eab97538af18381243f5337bf3d29e4b21098f
(https://bugs.freedesktop.org/show_bug.cgi?id=103210)

The only place where `tp_palm_tap_is_palm()` is called is if the more
sophisticated palm detection has already decided that this is not a palm,
so it should never return true.
