Add a HasSecondaryButtons boolean config option which defaults to true for
devices with the INPUT_PROP_TOPBUTTONPAD and false for all other devices.
Only parse the SecondarySoftButtonAreas when this option is true, effectively
disabling the top buttons when it is false. Likewise, only initialize the
SecondarySoftButtonAreas property if we enable support for it.
This means that it is now safe to always set a SecondarySoftButtonAreas
default in 50-synaptics.conf, and that he section which was intended for
use with future pnp-id matching can be dropped, as that is now all handled
in the kernel.
While at also remove the comment about disabling the bottom edge area, as that
is now done automatically.

Enabling clicks in off mode also allows for the new Lenovo *40 series to use
the top software buttons while the touchpad is disabled. This benefits those
that usually disable touchpads altogether but still need the buttons for the
trackstick.
This changes existing behaviour, but TouchpadOff was always intended to stop
erroneous events while typing. Physical button presses are hard to trigger
accidentally. On the touchpads that TouchpadOff concept was originally
designed for the buttons are nowhere near the keyboard and are physically
separated from the touchpad anyway. On Clickpads, triggering a physical
click requires more force than accidentally touching the surface.

Clicking in the top soft button area causes the trackpad to begin
registering motion, even if the finger never leaves the top soft button
area. We don't want this kind of behavior for the top soft button area,
since it makes clicking and dragging items much more difficult when
using a pointing stick.

This was originally intended as a fixed xorg.conf option only (and still
largely is seen as such). Secondary software button are required only on a specific series
of touchpads and should be pre-configured by the system and/or the
distribution. As such, the property will not be initialized if it is not set
in the xorg.conf and will thus not respond to runtime changes.
Exposing the property in this way gives clients a chance of detecting if a top
software button area is present and thus adjust their behaviour accordingly.

It is possible for a click to get reported before any related touch events

Notice the BTN_LEFT event all by itself!
If this happens, it may lead to the following problem scenario:
-touch the touchpad in its right click area
-let go of the touchpad
-rapidly click in the middle area, so that BTN_LEFT gets reported before the
new coordinates (such as seen in the trace above, this may require some
practicing with evemu-record to reproduce)
-the driver registers the click as a right click because it uses the
old coordinates from the cumulative coordinates to determine the
click location
This commit fixes this by:
1) Resetting the cumulative coordinates not only when no button is pressed,
but also when there is no finger touching the touchpad, so that when
we do get a touch the cumulative coordinates start at the right place
2) Delaying processing the BTN_LEFT down transition if there is no finger
touching the touchpad
This approach has one downside, if we wrongly identify a touchpad as
a clickpad, then the left button won't work unless the user touches the
touchpad while clicking the left button.
If we want we can fix this by doing something like this:
1) Making update_hw_button_state return a delay; and
2) Tracking that we've delayed BTN_LEFT down transition processing; and
3) When we've delayed BTN_LEFT down transition return a small delay value; and
4) If when we're called again we still don't have a finger down, just
treat the click as a BTN_LEFT
But this is not worth the trouble IMHO, the proper thing to do in this
scenario is to fix the mis-identification of the touchpad as a clickpad.

When a button click and new coordinates get reported in one go we sync the
cumulative coordinates to the old x and y, rather then the newly reported ones.
This keeping of the old coordinates causes the following issue:
-touch the touchpad in its right click area
-let go of the touchpad
-rapidly click in the left click area (or middle area), so that the
new location and the click get reported in one syn (may require some
practicing with evemu-record to reproduce)
-the driver registers the click as a right click because it uses the
old coordinates from the cumulative coordinates to determine the
click location

Unless the motion has started outside the soft-button area.
Note that we must start reporting motions regardless of whether we think we're
in the button area or not as soon as we've switched to using cumulative
coordinates, since then the coordinates are no longer absolute.
This fixes the reporting of unintended motion just before a click in a soft

New generation of laptops with trackstick do not have physical buttons
associated with the trackstick, but instead rely on software buttons at
the top of the clickpad.
Adding a secondary software button area for this purpose.
As we're likely detecting the devices that need it based on udev tags
and MatchTag configuration items, this area doesn't need to be exposed
through properties. So static configuration is fine.

synaptics offers an option to make parts of the touchpad insensitive. This
is ie useful to do palm avoidance rather then palm detection (which may be
unreliable) by disabling an area of 15% on the right and left side of the
touchpad.
Currently a motion which has started inside the active area, stops as soon
as it moves outside of the active area.
If a motion started inside the active area and thus has already generated some
move events, this makes no sense. If the user moves outside of the active
area in this case, this is very likely because the user wants to continue
the motion.
This commit allows such motions to continue normally.
I would like to thank Juerd Waalboer for the basic idea, some coding and lots
of testing for this fix.

When trying to do a 3 fingerclick on a touchpad which only tracks 2 touches,
this may register as a 3 or 2 fingerclick depending on the order in which
the touchpad detects the fingers. If the 2 outer fingers of the 3 get seen
first, then the 2 touches will be too far apart for the heuristic to see
them as being close together, and the click gets counted as a 2 finger click.
A user will likely never do a 2 finger click with a 3th finger resting
somewhere else on the pad, where-as the above misdetection of the clicks is
a real issue, so simply always count a click with trippletap set as a
3 finger click on pads which track less then 3 touches.

If a slot's ABS_MT_TRACKING_ID event was received during SYN_DROPPED, the
driver isn't aware that a touchpoint has started or ended in that slot. When
the next ABS_MT_TRACKING_ID event arrives, the driver would unconditionally
close or open a new touchpoint. This could lead to two or more touchpoints
being opened in the same slot, the first of which is never terminated.
Or it could lead to a touchpoint being terminated that was never opened.
The event sequences that trigger this are:
ABS_MT_TRACKING_ID 83
ABS_MT_TRACKING_ID -1
SYN_DROPPED // new touchpoint started here
ABS_MT_TRACKING_ID -1
and
ABS_MT_TRACKING_ID 83
SYN_DROPPED // touchpoint ended here
ABS_MT_TRACKING_ID 84
ABS_MT_TRACKING_ID -1
We don't properly handle SYN_DROPPED, but we can avoid this by only starting a
new touchpoint when we transition between -1 and a valid tracking ID.

For percent-based configuration in the form of

one device unit overlap. This was neither documented nor useful, because
leaving a 1% gap leaves an actual gap between the buttons. Allow for an

What's picked in that case depends on the implementation of

When disabling the device, reset num_active_touches to zero. Otherwise,
num_active_touches stays at the value it was on DeviceOff(). Future touches
add to that value until the index may go past priv->open_slots[].
That causes spurious memory corruption on touch ends.
And as of 55fc42e7c9b4948cadd4f98ef7b6a3b12e268e3e we ignore pre-existing
touches anyway.
Test-case:
- place num_touches fingers on the touchpad
- xinput disable <device>
- lift fingers
- xinput enable <device>
- place finger on device, num_active_touches is now (num_touches + 1)
