> Wie ktoś jak uzyskać numer/id bieżącego pulpitu?!?

Już wie! Oto rozwiąznie (choć nie w Qt):

#if defined(Q_OS_LINUX) || defined(Q_OS_UNIX)
    Display* lDisplay = XOpenDisplay(nullptr);
    int lScreen = DefaultScreen(lDisplay);
    Window lRootWindow = RootWindow(lDisplay, lScreen);
    Atom lAtom(XInternAtom(lDisplay, "_NET_CURRENT_DESKTOP", True));
    if(lAtom == None)
        qFatal("no atom\n");

    unsigned long nitems, leftover;
    unsigned char *data = nullptr;
    int actual_format;
    Atom actual_type;

    if(XGetWindowProperty(lDisplay, lRootWindow, lAtom, 0L, (long)200, False, AnyPropertyType, &actual_type, &actual_format, &nitems, &leftover, &data) != Success)
        qFatal("XGetWindowProperty failed!");

    printf("ok\n");
    printf("desktop = %d\n", (unsigned int)*data);
#endif
