[vtkusers] VTK OPENGL UBUNTU NVIDIA error

[Jose Ignacio Prieto]

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.
I don't know how to report bugs the institutional way. I will try to assign
a mantis ticket later.
