On my system the touchscreen keeps working after using a QML app. It still gets gestures (e.g 3 fingers on the screen) but it won't work on some windows. Furthermore, I can't drag windows by the decoration any more. Multifinger gestures keep working because they do not depend on pointer/mouse events, which is what gets broken here (namely mouse pointer emulation from touch events).

[Dx-packages] [Bug 1307701] Re: Unity does not get touch events when QML apps running
One thing that smells fishy is that the qml app starts getting touch events even before compiz/unity7. I think that this should not happen as the qml app does not subscribe for ownership events (unlike compiz/unity7) and ownership is offered to compiz/unity7. So the qml app should only get touch events once compiz/unity7 rejects ownership of the touch sequence, but that's just not happening (qml app was already receiving events from that touch sequence by that time). -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

[Dx-packages] [Bug 1307701] Re: Unity does not get touch events when QML apps running
Any QML application at all will do (such as Item
{width:600;height:600})
What seems to be happening, from what I've learned so far:
- user touches on a qml application
- xserver sends the resulting touch events to both the qmlscene and to
compiz/unity7
- xserver offers ownership to compiz/unity7
- qmlscene does XIGrabDevice on the touch screen
- compiz/unity7 rejects the touch
- user lifts finger and touch ends
- qmlscene does XIUngrabDevice on the touch screen
- user lands a new finger, this time on the desktop
- xserver still has in its bookkeeping that the previous touch is active and
thus deny pointer emulation for that new touch
And from that point onwards xserver is left with a bogus state, even
after the qml app is closed. Restarting it being the sure way to clean
it up and reproduce the issue anew (otherwise further issues seem to
crop up)

[Dx-packages] [Bug 1307701] Re: Unity does not get touch events when QML apps running
The problem does not occur in a Gnome Flashback (Compiz) session, so it is evidently a result of the interaction between the XInput2 touch grabs used in Unity 7 (through Geis), the passive Xinput touch subscriptions in Qt, and the pointer emulation in x.org. Multi-touch pointer emulation in XInput2 is documented as acting the way as described in this bug when multi-touch sequences are neither accepted nor rejected (ie pointer emulation stops when the first touch ends - see http://who-t.blogspot.ca/2011/12/multitouch-in-x-pointer-emulation.html) although it is unclear why the emulation does not resume when all touches have stopped. It sounds like the Unity touch support needs to add gesture accept/reject. -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

According to the XInput2 documentation, this should forward the TouchBegin to the clock, which should then do with it what it will. The clock should not be receiving emulated pointer events, because according to the XInput2 documentation, if Touch events are explicitly selected, pointer emulation is disabled for that client. It looks like either (a) the X server is in pointer emulation mode and never leaves, or (b) the client is doing some sort of grab on the touch (there is no evidence of this in the code) and not releasing it.

[Dx-packages] [Bug 1307701] Re: Unity does not get touch events when QML apps running
On a side note: multitouch in xorg is very problematic. Just now I had to reboot my xps touch screen laptop because the mouse pointer emulation logic no longer worked (pointer simply disappeared on touch). In another attempt playing with multitouch, xserver simply crashed and I was sent back to the login screen. -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

hmm, and pointer emulation actually still works for other apps when their windows are focused. You just can't focus them by tapping them. -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

[Dx-packages] [Bug 1307701] Re: Unity does not get touch events when QML apps running
So, when you run a QML app and tap on it, it seems that the mouse pointer emulation dies but multitouch events still flow normally as unity still responds to 3-finger (window drags, alt-tab switch) and 4-finger (show/hide dash, launcher drag) gestures -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.
