QT, VTK project on linux not running

I am trying to launch a ITK/VTQ project with Qt. The project runs on Windows 10, but not on Ubuntu.

I have the following error during launching the project:

X Error: BadColor (invalid Colormap parameter) 12 Major opcode: 1 (X_CreateWindow) Resource id: 0x4a00001 X Error: BadWindow (invalid Window parameter) 3 Major opcode: 3 (X_GetWindowAttributes) Resource id: 0x480001a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 2 (X_ChangeWindowAttributes) Resource id: 0x480001a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 2 (X_ChangeWindowAttributes) Resource id: 0x480001a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 2 (X_ChangeWindowAttributes) Resource id: 0x480001a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 2 (X_ChangeWindowAttributes) Resource id: 0x480001a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 7 (X_ReparentWindow) Resource id: 0x480001a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 2 (X_ChangeWindowAttributes) Resource id: 0x480001a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 10 (X_UnmapWindow) Resource id: 0x480001a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 12 (X_ConfigureWindow) Resource id: 0x480001a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 8 (X_MapWindow) Resource id: 0x480001a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 2 (X_ChangeWindowAttributes) Resource id: 0x480001a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 8 (X_MapWindow) Resource id: 0x480001a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 2 (X_ChangeWindowAttributes) Resource id: 0x480001a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 2 (X_ChangeWindowAttributes) Resource id: 0x480001a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 3 (X_GetWindowAttributes) Resource id: 0x480001a Erreur de segmentation (core dumped) 

Here is my code :

void ImageViewerWidget::InitRender() { /*** INITIALIZATION ***/ // init the actor m_texturedQuad = vtkSmartPointer<vtkActor>::New(); _openGLproperty = static_cast<vtkOpenGLProperty*>(m_texturedQuad->GetProperty()); // init the quad _quadPolyData = vtkSmartPointer<vtkPolyData>::New(); // create the texture object _textureCoordinates = vtkSmartPointer<vtkFloatArray>::New(); _textureCoordinates->SetNumberOfComponents(3); _textureCoordinates->SetName("TextureCoordinates"); float tuple[3] = {0.0, 0.0, 0.0}; _textureCoordinates->InsertNextTuple(tuple); tuple[0] = 1.0; tuple[1] = 0.0; tuple[2] = 0.0; _textureCoordinates->InsertNextTuple(tuple); tuple[0] = 1.0; tuple[1] = 1.0; tuple[2] = 0.0; _textureCoordinates->InsertNextTuple(tuple); tuple[0] = 0.0; tuple[1] = 1.0; tuple[2] = 0.0; _textureCoordinates->InsertNextTuple(tuple); // create the itk/vtk converter m_itkToVtkConverter = itk::ImageToVTKImageFilter<itk::Image<float, 3> >::New(); /*** Init the Renderer ***/ m_imageRenderer = vtkSmartPointer<vtkRenderer>::New(); m_imageRenderer->SetBackground(1,1,1); // Background color white m_imageRenderer->ResetCamera(); /*** Init the Render Window ***/ m_imageRenderWindow = vtkSmartPointer<vtkRenderWindow>::New(); m_imageRenderWindow->AddRenderer(m_imageRenderer); /*** Init the Shader ***/ SetActiveShader("BasicShader"); /*** Set Render Window to viewer ***/ // FIXME: the software crashes here on GNU/Linux viewer->SetRenderWindow(m_imageRenderWindow); } 

I found that the problem is here :

viewer->SetRenderWindow(m_imageRenderWindow); 

How I can correct this error message ?

Where is the problem ?
