[Wayland-bugs] [Bug 105409] Touchpad deadzone on Razer Blade Stealth

hid-record output take 2

Here's a longer hid-record output, this time I made an S shape that passed
through the deadzone, and a counter-clockwise half-circle around the touchpad.
The cursor stops moving at approximately 5.5s, which was at the end of the S
shape, and did not track the half-circle afterwards.

No, let's keep it closed so I don't have to spend any time on checking this bug
repeatedly. It's easy enough to reopen once confirmed it still exists.

--- Comment #7 from Peter Hutterer  ---
https://wayland.freedesktop.org/libinput/doc/latest/clickpad_softbuttons.html

Physical click in bottom right corner when software buttons are enabled =>
right click, otherwise always left click. Clickfinger requires 2 fingers to
trigger a right click.

Tap anywhere with a single finger (when enabled) -> left click, tap with two
fingers -> right click.

>From comment #0:
> 3. Tap on bottom-right area.
> Expected: Right click emulated

This feature doesn't exist. You can click in the bottom right corner and get a
right click, but tapping always produces a left click.

--- Comment #2 from Nate Graham  ---
I can't help but notice that a simple on/off switch would probably have been a
heck of a lot simpler: less code, higher reliability, and no regressions for
anyone, instead of this push-pull between people with good hardware who don't
want hysteresis, and those with crappy hardware who do. We'd probably have had
this issue solved long ago, rather than playing whack-a-mole with it into the
foreseeable future.

And now I promise that will be my last comment on the subject in this bug
report. :)

--- Comment #16 from Peter Hutterer  ---
How long did you keep you the finger there? The events stop at 1.84s and there
are a few events that have the same coordinates and would thus be filtered. But
afaict the recording stops 300ms after you say you entered the deadzone?

--- Comment #6 from Daniel van Vugt  ---
This bug doesn't bother me personally. I was only trying to reproduce the
downstream issue but now realise I misread "enable" as "disable". So maybe I
have the wrong bug link.

That said, I'm still a little curious about this one because it sounds like a
contradiction between:

Click methods:button-areas *clickfinger

and

"do you expect a tap on the bottom right button to be a right click? If so,
that feature doesn't exist in libinput."

It does work, for clicks but not for taps. So are you saying it was mutter
doing that emulation all along?

[Wayland-bugs] [Bug 105446] Tap to click doesn't work with bottom-right area mode

[bugzilla-daemon]

https://bugs.freedesktop.org/show_bug.cgi?id=105446

--- Comment #5 from Peter Hutterer  ---
all the libinput tools create their own context, nothing but the compositor has
access to the compositor's context. So libinput list-devices shows the default
settings, libinput debug-events uses the default settings unless specified
otherwise.

Apple touchpads have clickfinger enabled by default, so that's why the
bottom-right doesn't work as right click.

uhm, and I just realised: do you expect a tap on the bottom right button to be
a right click? If so, that feature doesn't exist in libinput.

[bugzilla-daemon]

--- Comment #35 from Nate Graham  ---
Preliminary impressions: Feels quite nice at 0.0 "libinput accel speed" (i.e
with no configuration). Definitely an improvement over the current profile. It
does still feel like there's an abrupt jump in acceleration between medium and
fast movements, but I think I could live with it.

Let's assume it's not reproducible right now. The latest downstream crash
report was from 1.10.1-1

We have no further information after that so maybe leave this open awaiting
more info and we can close it later if there is none.

--- Comment #4 from Daniel van Vugt  ---
It seems there's an inconsistency here:

Gnome Settings > Devices > Mouse & Touchpad > Tap to Click = ON
gnome-tweak-tool > Keyboard & Mouse > Touchpad > Mouse Click Emulation = Area

but...

Device:   Apple Wireless Trackpad
Kernel:   /dev/input/event15
Group:7
Seat: seat0, default
Size: 132x112mm
Capabilities: pointer gesture
Tap-to-click: disabled   < off?
Tap-and-drag: enabled
Tap drag lock:disabled
Left-handed:  disabled
Nat.scrolling:disabled
Middle emulation: disabled
Calibration:  n/a
Scroll methods:   *two-finger edge 
Click methods:button-areas *clickfinger <--- wrong one?
Disable-w-typing: n/a
Accel profiles:   none
Rotation: n/a

Is that correct for libinput to natively show its defaults rather than the
gnome settings? or a bug?

Can you show me which command you'd like run next?

--- Comment #3 from Peter Hutterer  ---
Tapping and click method is handled in libinput. What device is this? maybe
it's one of the ones where clickfinger is the default? libinput list-devices
will tell you, --set-click-method=buttons will force it in debug-events.

The --verbose argument will also tell you what state the various pieces are in.

--- Comment #2 from Daniel van Vugt  ---
Hmm, sounds like right-click emulation is higher level because libinput doesn't
see the difference...

Tested both libinput 1.10.1-1 (debian/ubuntu) and libinput master (d786b55):

Tap on bottom right area (shell incorrectly does a left click)
event15  POINTER_BUTTON   +74.96s   BTN_LEFT (272) pressed, seat count: 1
event15  POINTER_BUTTON   +75.06s   BTN_LEFT (272) released, seat count: 0

Click on bottom-right area (shell correctly does a right click)
event15  POINTER_BUTTON+3.94s   BTN_LEFT (272) pressed, seat count: 1
event15  POINTER_BUTTON+4.12s   BTN_LEFT (272) released, seat count: 0

Is the right click emulation done in mutter then?

I'm not sure this is a duplicate. It's a very different assertion.

Thanks for testing. The fuzz value is now in the systemd PR, so that should
close the bug once merged. The deadzone - there isn't anything we can do in
libinput, we're not getting any events from the hardware. This may be possible
to fix in the kernel but I'm not putting any hopes on that. Please attach a
dmesg and a hid-record log as well.

If it is between 1.10.1 and 1.10.2 and easy to reproduce, git bisecting will be
the fastest way to identify what changed. afaict that evemu-record scrolls just
fine, with only one motion event in the whole log.

I'll need a libinput debug-events --verbose output too please, that'll show if
the pressure sensitivity is getting in the way.

Best to run sudo libinput debug-events --verbose and check its output, it
prints when touches begin/end and what state the various features are in. There
are two possible sources for this bug - the kernel/hardware or touch pressure
detection. 

If you notice that a touch doesn't end when you release the finger, chances are
it's the kernel. But this is definitely something where you have to look at the
output and figure out what's going on.

Hmm, I just remembered I can test the legacy PS/2 mode using
'modprobe.blacklist=i2c_hid'. (Fortunately 4.15.x supports PS/2 fallback –
older kernels didn't.)

With the touchpad in PS/2 mode, libinput 1.10.2 missed only 2 scrolls out of
nearly a hundred.

So yes, looks like the problem is definitely caused (or at least worsened) by
the kernel RMI4 bugs.

Yeah, I rebooted after each change to be sure. I'll try and sort out an
evemu-record this evening. Thanks for all your work on this!

I forgot to mention: git master requires a reboot because it changes udev rules
for each device *and* it changes the kernel device. So basically, you'd have to
reboot every time after switching. But if the jumps happen only at the slowest
speeds, it's unlikely to be that issue. I'll need an evemu-record of one these
movements please, thanks.

There is one, except I only know of GNOME who has the screenshot part
implemented:

--- Comment #11 from L Holland  ---
So I've switched back and forth between HEAD and 1.10.2 and if there's a
difference in the fine pointer movement, it's very slight. They're both jumpy
when you move really slowly across the touchpad.

--- Comment #10 from L Holland  ---
Hi, I've just built and installed libinput MASTER HEAD (your build instructions
are great, BTW, thanks for that. Perhaps worth noting that I had to install
doxygen, check and valgrind as well to get the meson build to run)

Fine pointer motion is still rather jerky, I'm afraid. It's hard to be sure,
but I think there might be a slight improvement, but it's still not smooth
enough to be usable for fine work in e.g. GIMP or Inkscape. I'm going to try
reverting back to 1.10.2 to see if I can discern any difference.

Let me know if you want me to submit some logs as well.
