9 years agoChange default DPI to 1000
Peter Hutterer [Fri, 28 Nov 2014 00:09:21 +0000 (10:09 +1000)]
Change default DPI to 1000

400 used to be the default DPI for many mice but it it's not anymore. A survey
of mice shows that 400 is still common as one of the pre-configured settings
in switchable multi-resolution gaming mice, but devices with a single
resolution mostly favor 1000 dpi.

Let's make that switch now so that any future changes to the pointer
acceleration code assumes that resolution as a default.

For the touchpad, this has a bad side-effect, caused by our expectation of
mouse vs touchpad behaviours: our acceleration code ignores device type and
provides the same acceleration for the same physical movement. Unfortunately,
we expect touchpads to be significantly slower than mice.

The previous 400 DPI worked because it caused an acceptable slowdown on input.
e.g. on the T440 with a res of 42 units/mm, the scale coefficient was 0.37.
For 1000 DPI as default, this now results in 0.94, i.e. speeding up the
touchpad by a factor of 2.5. That is way too fast.

Adding touchpad-specific filter code is a bigger project, so let's just add a
fixme for now and scale the coefficient back to what it was before the
DPI default change. Effect: touchpad behaves as before.

Peter Hutterer [Fri, 7 Nov 2014 06:08:34 +0000 (16:08 +1000)]
evdev: use distance triggers to start scrolling

The previous code used delta/event as scroll trigger which roughly translates
to speed, but depends on the sampling rate of the device.

For slow two-finger motion, a user may move the height of the touchpad without
ever triggering scrolling. Change the _initial_ trigger to a cumulative
trigger, i.e. once the user moved past the threshold distance, scrolling
starts regardless of the speed.

Once scrolling is engaged, the original trigger of threshold/event is
required to engange the second scroll direction.

Note that except for really slow movements, it's very easy to engage both
scroll directions on a touchpad. This is intentional, libinput does not have
enough semantic knowledge to know if horizontal scrolling is needed. So we
provide some direction locking but not much, it's up to the
client/toolkit/widget to decide if both scroll directions should be handled.
Add a comment to clarify that in the public doc.

touchpad: Disable touchpads on trackpoint activity

Some laptops with both a clickpad and a trackpoint have such a large touchpad,
that parts of the users hands will touch the pad when using the trackpoint.
Examples of this are the Lenovo T440s and the Toshiba Tecra Z40-A.

This commit makes libinput automatically disable the touchpad while using
the trackpoint on these devices, except for the buttons, as people may want
to use the touchpad (hardware or soft) buttons while using the trackpoint.

9 years agotouchpad: Add tap suspend / resume
Hans de Goede [Sun, 28 Sep 2014 11:21:05 +0000 (13:21 +0200)]
touchpad: Add tap suspend / resume

While e.g. disabling the touchpad while the trackpoint is used, we want to
stop sending tap (or scroll or motion) events. We cannot use tp_clear_state at
this time as that will also release any touchpad buttons pressed, breaking
dragging with the trackpoint using the touchpad or clickpad buttons.

Calling tp_release_all_taps() and then ensuring that we do not call
tp_tap_handle_state as long as the trackpoint is in use, is enough to disable
taps when the trackpoint is in use.

However when the trackpoint stops being used, we cannot simply start calling
tp_tap_handle_state() again, we first need to sync the tap.state to the current
reality, specifically if fingers are down it must be TAP_STATE_DEAD, so that
their releases do not trigger the log_bug_libinput on a release in
tp_tap_idle_handle_event.

Directly messing with tap.state from outside evdev-mt-touchpad-tap.c is not
good, so add tp_tap_suspend and tp_tap_resume functions for this.

9 years agotouchpad: Rewrite / fix tp_release_all_taps
Hans de Goede [Sun, 28 Sep 2014 11:21:04 +0000 (13:21 +0200)]
touchpad: Rewrite / fix tp_release_all_taps

Before this commit tp_release_all_taps would call tp_tap_handle_timeout, which
is a nop when in state DRAGGING. tp_clear_state then releases all touches and
calls touchpad_handle_state which moves the state to DRAGGING_WAIT, and the
button 1 release will only be done after the tap-timeout, rather then directly
as it should on tp_clear_state.

This commit fixes this by instead of calling tp_tap_handle_timeout, directly
releasing pressed buttons and switching to state DEAD or IDLE depending on
fingers_down.

Besides fixing this issue, this rewrite also makes it possible to use
tp_release_all_taps outside of tp_clear_state, which will be used to add
tap suspend / resume functionality in a follow up commit.

core: Add internal event notification mechanism

For features like e.g. disable-touchpad-while-typing, it is necessary for one
device to be able to listen into another device's events.

It is tempting to use the existing device_added / device_removed mechanism
to give e.g. the keyboard a link to the touchpad, and make the keyboard code
disable / re-enable the touchpad but this is wrong. This needs to be a setting
of the touchpad, and the policy for things like which events to count as
activity, and what sort of timeout to use to consider the device idle, belongs
in the touchpad code not in the keyboard code.

Add an event listeners mechanism so that the touchpad can listen for (e.g.)
keyboard events, and respond to these itself.
