<br>
with all of your driver woes I think it's likely that you're
unintentionally using Ubuntu's Mesa libGL rather than NVIDIA'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's why the
class has been disabled if the driver is Mesa.<br>
<br>
To confirm which driver you're using include the output from<br>
<br>
ctest -R LoadOpenGLExt --verbose<br>
<br>
Please include this in your bug report.<br>

<div>I finally installed and uninstall nvidia drivers and
xorg and nothing worked. Then I realized that the
conflicting file
Rendering/volumeopengl/vtkopenglgpuvolumeraycasmapper.cxx
was modified 8 days ago. I switched back from head to
v.6.0.0 and it worked again.<br>

I don't know how to report bugs the institutional way. I
will try to assign a mantis ticket later. <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 moz-do-not-send="true"
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't work anymore.
Specifically I had a volume rendered with
vtkGPUVolumeRayCastMapper and now it shows
an error <br>

I have installed-uninstalled nvidia drivers
many times but I have no clue on what is
going on. Seems that it changed
/usr/local/x86.../libGL.so and libGLU.so <br>
</div>
I am using ubuntu 12.4, my graphics card is
nvidia geforce 9800 and qt 4.8.5<br>
<br>

Thank you very much!<span><font color="#888888"><br>
