Check your graphics drivers. You can use tools like `glxinfo` to tell<br>
you which OpenGL version is supported. ParaView now requires 3.2 or<br>
newer. If you cannot upgrade your graphics drivers, you can use<br>
software OpenGL implementation packaged by ParaView binaries as<br>
follows:<br>
<br>
.../paraview --mesa<br>
<br>
Hope that helps,<br>
