To fix this we need the QInputDeviceInfo to be cherrypicked from Qt5.6 to Qt5.4. If that won't happen during OTA10 timeframe we must mirror it ourselves.

@zsombi
agreed. There is code in unity8-private that does this detection (we import that in address book and messaging - yuck!) that in worse case could be used in sdk if the Qt code is not ready.

In order to get this working we need to drill holes in apparmor to the following:
  /sys/devices/**/input*/ rk,
  /sys/devices/**/input*/** rk,
  /sys/class/ r,
  /sys/class/input/ r,
  /run/udev/data/** r,

From these the last one especially is the biggest problem, because all apps will have access to the device data, which is bad. So security is alerted and they disagree on opening those holes, which is understandable.

The solution seems to be Mir to expose these somehow in a more secure way, to which we would need some adaptation.

The last branch linked to this bug# handles the forwarding in a nested session. Without it the example code above will not get any input devices when connected to a session compositor. We plan to get that MP out in the next mir release.

The patch does not apply at least when added to apply as the last patch on top of lp:~kubuntu-packagers/kubuntu-packaging/qtsystems-opensource-src

I tried also with the upstream patch set 23 from https://codereview.qt-project.org/#/c/101049/ instead of the 20 currently in use.

I wasn't pinged about landing this or anything so maybe I'm just too early anyway trying it out :) Please ping me whenever you need it. It'd be useful information also if the inputinfo patch itself should be upgraded to the version 23 as mentioned.

We'd need the upstream to merge the patch and a new Mir API patch to qtsystems based on top of the newest upstream InputInfo patch version.

An older Mir API patch was posted in comment #8 but it would need rebasing. I think that could come from Andreas still?

Now patch set 26 replaced patch set 25, and the Mir patch no longer applies. The attached patch is a rebased version to 26, but we just heard patch set 27 and 28 are upcoming soon... so this will continue still.

For the record, it seems the we will want Mir backend with the naming more like qinputdeviceinfo_mir.cpp/h, to match patch set 26 and what Unity 8's internal copy of the _linux backend currently, instead of the current patch's qinputmanager/_udev/_mir. So the Mir patch would need redoing.

Timo Jyrinki (timo-jyrinki) wrote :

Ok, patch set 31 that now includes the Mir backend is in the silo 038 https://requests.ci-train.ubuntu.com/#/ticket/1723

The UITK branch is however outdated. As Unity 8 is already using an internal copy of this, the main benefit from the landing would come via UITK. Unity 8 would also switch to use the qtsystems version instead.

If the patch set 31 is not complete enough or the UITK branch won't be ready to be tested by next Friday, this'd be OTA-14 instead of 13.

Patch set #43 in upstream was finally merged together with the Mir integration. The silo is up-to-date for vivid/xenial/yakkety, and includes also the switch to the upstream version of the screen blanking prevention patch.

However when trying to run eg the qml-inputinfo.qml (from command line, any desktop hint is ok, qmlscene --desktop_file_hint=/usr/share/applications/mediaplayer-app.desktop qml-inputinfo.qml) I just get a blank screen, and running the inputinfo non-qml executable I get segfault.

Tested both on vivid (rc-proposed) and xenial (staging).

Weird thing is when I load the source into qtcreator and build with same qmake line (and building mirclient stuff), I don't get segfaults.

I did have to edit source to even get it compiling.
In qscreensaver_mir_p.h there is int m_keepDisplayOnRequest
but it is m_keepDisplayOnRequestId in qscreensaver_mir.cpp
I don't see how that would even compile when mirclient is enabled

Currently I'm getting:

So no devices for some reason but also at least more output and less crashes.

Right now tested on xenial (staging channels) only.

With patch set 3 ./inputinfo now works, gives 1 device on krillin (touchscreen) and 2 input devices on Chromebook (keyboard, and touchscreen).

qml-inputinfo.qml gives 0 devices on krillin (as there are no mouse or keyboard connected which the example checks) and 1 device (keyboard) on Chromebook (no mouse, only touchpad).

I guess this is all correct now regarding what those example applications should be doing? And there is no crash anymore.
