    Sure. But the question was: why do you need to start your app as root?

      thats all of load library i have found.

      loaded library "/usr/local/qt5/plugins/platforms/libqeglfs.so"
      loaded library "/usr/local/qt5/plugins/egldeviceintegrations/libqeglfs-brcm-integration.so"
      loaded library "/usr/local/qt5/plugins/imageformats/libqgif.so"
      loaded library "/usr/local/qt5/plugins/imageformats/libqicns.so"
      loaded library "/usr/local/qt5/plugins/imageformats/libqico.so"
      loaded library "/usr/local/qt5/plugins/imageformats/libqjpeg.so"
      loaded library "/usr/local/qt5/plugins/imageformats/libqsvg.so"
      loaded library "/usr/local/qt5/plugins/imageformats/libqtga.so"
      loaded library "/usr/local/qt5/plugins/imageformats/libqtiff.so"
      loaded library "/usr/local/qt5/plugins/imageformats/libqwbmp.so"
      loaded library "/usr/local/qt5/plugins/imageformats/libqwebp.so"

      so with this it's seem i use the eglfs backend. Now i can't tell if it's normal or not...

      and jslum in ancien projet on a raspberry pi i always need to need to be root to start a application ... so i tought it's always like this but it seems that isn't necessary.

        Ok, so it means no window manager.

        Can you post an image of what you are getting exactly on screen when running your application ?

              Firat thing, you won't have any window decoration. The EGLFS plugin only works in full screen mode.

              Can you test the LinuxFB plugin ?

                I have some new. I finally have the push button on my raspberry pi... but the label still missing. Some one give me a program that work correctly on another raspberry pi, but I have the same issue so think it's missing file on my rasp... but i don't understand why i use "apt-get install qt5-default" to install the lib....

                how i do that? also all programme i run in full screen mod.

                      @CrazyCreepy How do you position the widgets (label and button)? Do you use layouts?

                          Then you should put them in a layout in your main widget.

                              @SGaist I run my program with this commande ./test -platform linuxfb. The result is i have some graphique bug like 2 curso one white and the second is black.If i pass the cursor on windows programs the icons of my task bar appear and the text is always missing. but it's not in full screen.

                              look the picture:
                              alt text

                                Is it me or are you trying to run an application on the framebuffer while also having Xorg running ?
