Description Jean-François Fortin Tam 2016-06-24 01:38:32 UTC

+++ This bug was initially created as a clone of Bug #1281881 +++

Testing the Fedora 24 Workstation final liveUSB image, I see a comeback of bug #1281881, except it's the other way around now: the tablet screen's stylus works, but the touch functionality doesn't (nothing on the screen reacts to finger touches).

Back in November the issue was that libinput did not yet support tablet devices, now I'm not sure what the new issue is... maybe a regression from this:

The fix is in Dmitry's input tree now.

Comment 1 Jean-François Fortin Tam 2016-06-26 16:05:48 UTC

Actually I also see the same issue on a fully updated F23, with the 4.5 kernel...

Comment 2 Peter Hutterer 2016-06-28 23:13:50 UTC

do you see touch events when running libinput-debug-events?

Comment 3 Jean-François Fortin Tam 2016-07-05 15:49:41 UTC

> do you see touch events when running libinput-debug-events?

Yep, as a matter of fact I do! Just that nothing in GNOME Shell / GTK / etc. reacts to them. See the presence of the "TOUCH_FRAME" events below:

wait, is this really the output? That would indicate that something is broken. there should be touch down/motion/up events too. Can you get me an evemu-record of a touch sequence on device please

Comment 6 Peter Hutterer 2016-08-15 04:53:20 UTC

ok, summary here is that the fix we pushed into the kernel was buggy. Ping has fixed them up now and the various reverts are filtering through to the stable branches. Keep an eye on kernel updates, there should be one soon that fixes it.

Comment 7 Jean-François Fortin Tam 2016-08-27 16:43:36 UTC

Hi Peter, it seems the fix has trickled down through the last stable kernel updates in Fedora 24... however another regression appears: the stylus and the touch input work... the problem is that the stylus doesn't cancel out the touch input anymore, so it makes it impossible to draw because the hand is triggering a bunch of events at the same time as the stylus...

There's a workaround (and thanks to 'whot' an explanation in the comments) for that here:

fwiw, I'm 'whot' :)

the answer in that question is correct though - the touch device needs to be handled by the wacom driver too for user-space touch arbitration to work.

Because the sort order is different on fedora you'll need to name this file 99-<something>.conf (sort higher than our 90-libinput.conf). And I recommend using the full device name in MatchProduct but that's up to you.

I'm closing this bug now based on comment #7.

I'm a bit confused, does this mean further libinput updates already scheduled to trickle down will fix this behavior where the palm of my hand messes things up when I try to use the stylus, without me needing to add some local hacks on my system?

Comment 11 Peter Hutterer 2016-08-31 01:15:28 UTC

for the time being (especially for F24 lifetime) you'll need to keep the hack. We haven't yet switched Fedora to use libinput by default for tablets so even when libinput has touch arbitration it won't control both devices (and thus can't arbitrate). F25 is a different matter, I still have to decide on that

Comment 12 Jean-François Fortin Tam 2016-09-07 18:16:02 UTC

I just realized that touch drag is broken, too, so kinetic scrolling (in Nautilus, Evince, etc.) does not work. Should I be creating a separate bug report about this?
