      Perhaps you&#39;ve linked libraries from multiple drivers? I&#39;ve seen
      this test segv when two GL libs are mixed, the render context is
      invalid and glGetString returns NULL. In that case it&#39;s not a bug
      in VTK but rather a build issue since you should only be using a
      single OpenGL library.<br>
      <br>
      Could you report the output of<br>
      <br>
      grep ^OPENGL_ CMakeCache.txt<br>
      <br>
      If you haven&#39;t already rm your build re-configure and re make. you
      should do this after any changes to the open gl drivers.<div><div class="h5"><br>

              <div>Jose, <br>
                <br>
                with all of your driver woes I think it&#39;s likely that
                you&#39;re unintentionally using Ubuntu&#39;s Mesa libGL rather
                than NVIDIA&#39;s. At least this will explain the error
                report below.<br>
                <br>
                Mesa, depending on release version and renderer, has
                some bugs that prevent this class from working correctly
                and some or all of the vtkOpenGLGPUVolumeRayCastMapper
                ctests fail. That&#39;s why the class has been disabled if
                the driver is Mesa.<br>
                <br>
                To confirm which driver you&#39;re using include the output
                from<br>
                <br>
                ctest -R LoadOpenGLExt --verbose<br>
                <br>
                Please include this in your bug report.<span><font color="#888888"><br>

                                            <div>Hi, I know this is not
                                              exactly vtk but I hope you
                                              can get my opengl error. I
                                              made a mistake updating a
                                              driver and now I have no
                                              idea how to solve it. <br>
                                            </div>
                                            I got interested in trying
                                            itk filters solved through
                                            gpu, so I installed CUDA
                                            following this link:<br>
                                            <a href="http://docs.nvidia.com/cuda/cuda-getting-started-guide-for-linux/index.html#package-manager-installation" target="_blank">http://docs.nvidia.com/cuda/cuda-getting-started-guide-for-linux/index.html#package-manager-installation</a><br>

                                          </div>
                                          Then I realized they were
                                          useless so I built a new set
                                          of vtk6.1+itk4.5+qt4.8.5. The
                                          problem is that my old files
                                          compiled with
                                          vtk6.1+itk4.5+qt4.8.4 don&#39;t
                                          work anymore. Specifically I
                                          had a volume rendered with
                                          vtkGPUVolumeRayCastMapper and
                                          now it shows an error <br>
