My problem seems like this Touch not working when running Qt for embedded using eglfs platform

So, I have built the QT 4.8.5 with eglfs support by using this manual

My flags is:

./configure -qpa -arch arm -xplatform qws/linux-imx6-g++ -no-largefile -no-accessibility \

        -opensource -verbose -system-libpng -system-libjpeg -system-freetype -fast -opengl es2 -egl -confirm-license \

        -qt-zlib -qt-libpng -no-phonon \

        -make examples -make demos \

        -I /tftpboot/rootfs/usr/include \

        -L /tftpboot/rootfs/usr/lib \

        -R /tftpboot/rootfs/usr/lib \

        -release -make libs -exceptions -no-qt3support -prefix /opt/qt4


X server is started like this: "Xfbdev -nolisten tcp -mouse tslib,2,device=/dev/input/event2 -mouse mouse,2,device=/dev/input/mice -keybd keyboard,,device=/dev/input/keyboard0&"

The touch, mouse and keyboard are working without any problem in both X11 and matchbox-window-manager. So, I can launch xterm or matchbox window and operate with it.

However, if I launch any QT 4.8.5 application it is started correctly but doesn't react on any input. Moreover, click goes through application interface. I mean that I can click on icons in matchbox window even through launched application's GUI.

By the way, I launch QT applications like this: ./some_qt_examples -platform eglfs

This is a console output:

Opened display 0x33ec74f8

Initialized display 1 4


Unfortunately, I have never seen the same issue before. And I can't find any suitable solution for this. Moreover, I can't understand a reason of it.

So, now I forced to ask a help. Can someone guide me?

I will be appreciate for any advices!
