Build ID: 20160425114621
Steps to reproduce:
On linux in ubuntu 16.04 using firefox 46, drag does not work even with
the new gtk3 changes.
My printenv includes MOZ_USE_XINPUT2=1 by adding it to /etc/environment
and rebooting.
I've tried about:config dom.w3c_touch_events.enabled set at the default
"2" and also changed it to "1"
Actual results:
Using my touch screen to touch and drag does not scroll the screen. It
just hi-lights any content to select it.
Expected results:
The page should scroll up and down.

Touch event support on GTK3 requires APZ, which in turns requires e10s.
e10s is not yet on by default in Firefox 46.
I believe e10s can be turned on in 46 release by going to about:config
and adding a pref named "browser.tabs.remote.force-enable", with the
value set to true. However, please be aware that this is not a supported
configuration.

Note that e10s is now enabled by default in some configurations in
Firefox 48. If you have e10s enabled and are running a GTK3 build of
Firefox, adding MOZ_USE_XINPUT2=1 to your environment (until bug 1207700
is fixed) should be all that's necessary for touch-scrolling to work.

Yes, and your about:support explains why:

See [1] for more information about e10s and add-ons.
If you're confident that e10s doesn't break any of your add-ons (or if
you don't care about potentially breaking some of your add-ons), you can
force-enable e10s as described here [2].

You need to run Firefox with MOZ_USE_XINPUT2=1.
To enable that every time you can:
1. "cp /usr/share/applications/firefox.desktop ~/.local/share/applications/firefox.desktop".
2. Open "~/.local/share/applications/firefox.desktop" with text editor.
3. Modify the line "Exec" to add "env MOZ_USE_XINPUT2=1" in front of "firefox".
4. Save it then reload GNOME (e.g. logout then login).
5. Open firefox again.
If you have e10s enabled, drag and scroll should be working.

Thanks. One more question: could you post the "Configure options" from
about:buildconfig? I just want to verify that you're running a GTK3
build, since touch event support requires GTK3.

I'm not seeing "--enable-default-toolkit=cairo-gtk3" in your configure
flags, which I guess means you're not using a GTK3 build.
Are you using an official build of Firefox (downloaded from [1])? If
not, where did you get your Firefox build from?

I'm using firefox (from official repos) on Ubuntu 17.04. AFAIK it should
be compiled with gtk3 support.

Talked to Ehsan abut this. He wasn't setting MOZ_USE_XINPUT2=1. When
that's set it works for him.

You're right, the Ubuntu 17.04 Firefox package is linked against GTK3.
Could you try a Nightly build from here [1], and see if it works, and if
it doesn't, can you post what the Nightly build says in about:support
under "Asynchronous Pan/Zoom"? (I ask because in Firefox >= 53, we
changed the way touch support is reported there to be more accurate (bug
1282306), and that may give us more information.)

I have the same problem as Marzanna (I'm however, on OpenSUSE Tumbleweed).
My touch device is a "Wacom ISDv4 101" in a Fujitsu Lifebook T902.
Most of the tested stuff was the same for me, just my build
configuration looks different (it has the gtk3 flag)
I just downloaded a nightly build (56.0a1) and started it with MOZ_USE_XINPUT2=1.
The APZ-Line in about:support now states: "wheel input enabled; touch input enabled; scrollbar drag enabled"
Neither 1, nor 2 for dom.w3c_touch_events.enabled makes it work for me.

Do you know if touch support works for you in other applications? From
googling it seems like at least some people are having trouble getting
this touch device to actually produce touch events in any application.

Touch seems to work in Chromium (scrolling and swiping), as well as
Xournal.
Additionally, in Chromium I tried:
document.addEventListener('touchstart', ...);
which worked and only fired when I used my finger as input.
But I can't tell you how exactly they implemented this, since, in a very
short attempt, I was not able to get one of the touch demo applications
of Qt to work.
The driver detects the device as 3 inputs:
- Pen
- Eraser
- Finger touch
in /dev/input, there is a mouse{X} file that only outputs data when the finger touches the screen. (And a second file for pen + eraser).
xinput list-props for the registered touch input brings the following
output:

That's as much information as I can give you.
If you have any other idea how I could debug this for you, please let me know.

Karl, do you have any suggestions for how we could investigate this
further, short of acquiring a device of the model in question and
debugging each of Chromium and Firefox to see how they come to differ in

Interesting that even the Qt demo didn't work for hiwatari.seiji.
Might be worth checking the device sends core events with "xinput list".
But if it is generating other mouse events, then I guess it is.
Botond, if you are keen to debug Firefox remotely, then adding logging to
nsWindow::OnTouchEvent() for MOZ_LOG=Widget:5 may provide some initial clues.
It may be possible to use https://xtrace.alioth.debian.org/ to log X Events,
but I haven't checked whether that has support for details of XInput2 events.
Even if it doesn't show details, it may still be possible to observe whether
there are any XInput2 events at all. These logs tend to be rather large.
xinput test-xi2 <device id> may be a simpler way to get some info about what
the device is doing. I don't know whether or not this will contain helpful
info.
Beware that there are known problems either with the design of XInput 2 or
GDK's interpretation of the events, as tracked in the dependencies of bug
1207700.

You could try the following suggestions from Karl:

Steps for this would be something like:
1. Install 'gtk3-demo' program. On Debian, it's found in the
'gtk-3-examples' package.
2. Run gtk3-demo
3. Switch to the "Gestures" page
4. Click "Run"
5. In the window that opens up, perform some touch gestures,
and see if the window reacts to it in any way. For me,
a one-finger drag results in a line being drawn, and a
two-finger gesture results in a square being shown.

Steps for this:
1. Install the 'xinput' program. On Debian, it's found in the
'xinput' package.
2. Run 'xinput --list' to see a list of your devices, and note
the device ID for your touch device.
3. Run 'xinput --test-xi2 <id>', where <id> is the id from the
previous step.
4. Perform some touch gestures, and paste the output of the
command.

On paper, the touch device in my notebook should be multi-touch. Unfortunately, only single touch gestures worked.
Just for fun, I disabled the "Gesture" option with xsetwacom for the device in question.
Suddenly, the multi-touch gestures started to work as well (in gtk3-demo, as well as chromium). nice ;)
(No change for Firefox)
The output of the 'xinput --test-xi2' command :

XInput2 is not enabled by default because it causes other side effects
that are undesirable - see bug 1207700 and its dependent bugs. Those
bugs need to be fixed before XInput2 can be enabled by default.
