I confirm that the Qt from https://launchpad.net/~canonical-x/+archive/x-staging does XISelectEvents on the master pointer (instead of the touchscreen slave device, as previously) and that the resulting behavior of the xserver is good. Ie., touch ownership mechanics work properly and mouse pointer emluation from touch events keeps working as well. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1307701 Title: xserver mouse pointer emulation from touch breaks with QML app. To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1307701/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

Touch events are reported to both qmlscene (from the slave device) and to compiz (from the master device). compiz rejects the touch sequence and it's not delivered to anyone else 2- user now presses on the desktop background. TouchBegin, TouchOwnership and further TouchUpdates are sent to compiz. 3- compiz rejects the touch sequence. TouchPuntToNextOwner fails to emulate a pointer and pass it to nautilus as it still thinks that touch 1 is active. And as per pointer emulation rules, only the oldest active touch is used for touch emulation. From the logs, the lines are: [ 9223.917] (II) TouchPuntToNextOwner: touch 2 [ 9223.917] (II) - Not all older pointer emulated touches have been seen yet. Oldest touch(client_id=1, active=1, pending_finish=0, emulate_pointer=1). 4- user lifts his finger So that scenario on touch 1 clearly left xserver in an inconsistent, buggy, state.

Attaching detailed xserver log. The following steps were taken: 1- sudo restart lightdm (to restart the X server. so that de have a clean slate) 2- run a very simple qml app with qmlscene 3- tapped on that qmlscene window (touch id 1) 4- tapped on the desktop area (nautilus) (touch id 2) 5- sudo stop lightdm From the logs you can see that no pointer emulation was done for touch id 2 because xserver still thinks that touch id 1 is active. ** Attachment added: xorg_debug.zip https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1307701/+attachment/4106287/+files/xorg_debug.zip -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1307701 Title: xserver mouse pointer emulation from touch breaks with QML app. To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1307701/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

Excerpt from #xorg-devel: dandrader daniels, I've the following situation: clientX has a XISelectEvents(TouchBegin|Update|End, childWindowA, slaveDevice1); clientY has a XIPassiveGrabDevice(TouchBegin|Update|End|Ownership, rootWindow, AllMasterDevices) daniels, when a touch reaches xserver, it sends touch events to both clientX and clientY daniels dandrader: yes, events are delivered separately thorough master and slaves - i'd recommend not using slaves for anything at all dandrader daniels, but I believe it should send only to clientY, and only once clientY rejects the touch sequence should clientX finally start receiving the touch events (replayed), right? daniels dandrader: if both clients were listening on a master device, then you'd be right dandrader daniels, hmm got it. so what I'm seeing is the expected behavior then and I should modify clientX to select events on AllMasterDevices instead of on slaveDevice1 daniels, is that it? daniels dandrader: exactly So we have two problems here: 1- touch ownership mechanics won't work in our situation as Qt is talking directly to the slave devices whereas unity7 is talking to the master devices. 2- the xserver bug described in my previous comments where it gets confused with such situation and ends up with a borked internal state which ruins mouse pointer emulation So if we could avoid the situation in item 1 (by changing either Qt or unity7/Open Input Fw Grail code) we might (have to try it out to see) circumvent the bug in item 2. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1307701 Title: xserver mouse pointer emulation from touch breaks with QML app. To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1307701/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

[Ubuntu-x-swat] [Bug 1307701] Re: xserver mouse pointer emulation from touch breaks with QML app.
Is there a specific reason for calling XISelectEvents() for each slave vs using XIAllMasterDevices in QXcbConnection::xi2Select() in Qt? Would have to dig into Qt code to tell that. But my guess is that because it exposes QTouchDevice objects to applications. For every QTouchEvent you can get the QTouchDevice from where it came from. But it might be that it could work with XIAllMasterDevices just as well. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1307701 Title: xserver mouse pointer emulation from touch breaks with QML app. To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1307701/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 1307701] Re: xserver mouse pointer emulation from touch breaks with QML app.
The code in Qt that subscribes to slave device events is the explicit tablet-handling code. Checking the code, the touchscreen on my Dell XT2 is being treated as a tablet by the Qt code because it supports a stylus mode on one of its alternate devices. It sounds like the bug is in the Qt XCB QPA code, which explains why it only started occuring in QML apps after the switch to Qt 5.2. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1307701 Title: xserver mouse pointer emulation from touch breaks with QML app. To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1307701/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 1307701] Re: xserver mouse pointer emulation from touch breaks with QML app.
I think the XIDeviceEvent.sourceid would tell you from which device it originates. The XIDeviceEvent.deviceid member would be set to the master device, which might break things in a straight conversion. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1307701 Title: xserver mouse pointer emulation from touch breaks with QML app. To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1307701/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 1307701] Re: xserver mouse pointer emulation from touch breaks with QML app.
@Stephen: I guess that means that your device passes the following check: if (tabletData.valuatorInfo.contains(QXcbAtom::AbsX) tabletData.valuatorInfo.contains(QXcbAtom::AbsY) tabletData.valuatorInfo.contains(QXcbAtom::AbsPressure)) which you can check using xinput list-props $device_id or simply using evtest. I have a non-tablet and a tablet, they are both affected by the same problem, except that fixing the tablet use case will probably take a little more work. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1307701 Title: xserver mouse pointer emulation from touch breaks with QML app. To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1307701/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

I've just rebuilt Qt with a partial fix which only covers the non- tablet test case, and I'm glad to report that it solves the problem.
