Here are the gymnastics I have to go through to trick
the X11 Window system into placing windows where I want them:
I'm sure there are aspects of it which could be criticized.
The sz and pos are suspect because there were, at some point,
queried from the same sadistic window system.

void
MyDialog::locateFromSettings() {
     if( sizeSettingName().size() > 0 ) {
         QSettings settings;
         QSize   sz = settings.value(sizeSettingName(),sizeSettingFactoryDefault()).toSize();
         QPoint pos = settings.value(posSettingName(),posSettingFactoryDefault()).toPoint();
         if( sz.width() > 0 && sz.height() > 0 )
             resize(sz);
         if( pos.x() != 0 && pos.y() != 0 )
             move(pos);
         show();
         qApp->processEvents(QEventLoop::ExcludeUserInputEvents,5000);
         if( pos.x() != 0 && pos.y() != 0 )
             move(pos);
         if( sz.width() > 0 && sz.height() > 0 )
             resize(sz);
         raise();
     }
     showNormal();
     show();
     raise();
}
