    Downloaded and installed the Open Source version of Qt for Linux. When I launch "qtcreator" I get the following message:

    QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled
    QApplication: invalid style override passed, ignoring it.
    QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled

    Followed by a "Qt Creator - Plugin loader messages" dialog box saying that the QmlDesigner and QmlProfiler plugins can not be loaded.

    I am running Xubuntu 16.04 in VMWare (Fusion). All the packages mentioned in the Wiki are installed.

    hwinfo --gfxcard shows the following

    Config Status: cfg=new, avail=yes, need=no, active=unknown

    Is there an issue with 16.04? I recently upgraded from 14.04 and everything seems to work fine there.

    Thanks

      After looking at the output of "ldd qtcreator" a little more closely, I discovered that some nvidia libraries were being used instead of the standard openGL libraries. After uninstalling all the nvidia libraries, qtcreator now runs.

      However I still get this message:

      QApplication: invalid style override passed, ignoring it.

      I tried deleting ~/.config/QtProject as suggested but it did not fix the problem.

        @ajcurtis said in QtCreator can not load plugins UBuntu 16.04:

        QApplication: invalid style override passed, ignoring it.

        But it is running now? If so then just ignore that warning.
