[vtkusers] VTK+Qt on ubuntu 9.10

Hi,

Well, this is my problem when I debut on QT + VTK + QTCREATOR:

MainWindow::MainWindow(QWidget *parent) :
     QMainWindow(parent),
     ui(new Ui::MainWindow)
{
     ui->setupUi(this);
     vtkWidget = new QVTKWidget(this,QFlag(0));
     ui->verticalLayout->addWidget(vtkWidget);
     ui->verticalLayout->update();
     ren = vtkRenderer::New();
     vtkWidget->GetRenderWindow()->AddRenderer(ren);
     ren->SetBackground(1.0,1.0,1.0);
     ren->Render();----------------------->PROBLEM!!!! -->>>The  
inferior   stopped   because it received a signal from the Operating    
  System. Signal name : SIGSEGV - Signal meaning : Segmentation fault

}

When I debut, with Qtcreator everything is ok until the instrucction  
ren->Render() is executed and have the message: The inferior   stopped  
   because it received a signal from the Operating System. Signal name  
: SIGSEGV - Signal meaning : Segmentation fault.

I have the same message when at the command line i use qmake, make....

My Desktop PC  has: Ati X1300, the openGL runs so good and the qtdemo is ok.

On the other hand I have laptop HP with the same S.O ubuntu 9.10 and  
run QT+VTK+QTCreator, the different thing is the Card which is the  
NVIDIA, but i don't thing so it would be that because the openGl runs  
so good in my Desktop PC.

Another things is that in the Desktop PC I display two monitors in  
dual-mode thats mean that the graphic card configuration is good.

What happened?? I know, there are three topics QT,VTK and linux but I  
so sure the problem is VTK.

Thanks for all

Ruben.
