[vtkusers] VTK OPENGL UBUNTU NVIDIA error

[burlen]

Jose,

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.

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.

To confirm which driver you're using include the output from

ctest -R LoadOpenGLExt --verbose

Please include this in your bug report.
