Hi Bishwajit,

In order to use the GPU with the NVidia driver, you either need to use an X server or use EGL. -DVTK_USE_X=OFF > In this case, you have disabled X but not enabled EGL so you're left with OSMesa when you really intended to use the GPU instead. See https://blog.kitware.com/off-screen-rendering-through-the-native-platform-interface-egl/ for more details on configuring ParaView to use EGL. - Chuck
