The OpenGL informations, visible in Help → About dialog, are not easily recoverable in pvpython yet.

Here is how to do it.

On ParaView 5.6 and earlier versions:

```
import vtk as VTK
openGLInfo=VTK.vtkPVOpenGLInformation() 
session=servermanager.vtkSMProxyManager.GetProxyManager().GetActiveSession()
session.GatherInformation(session.CLIENT, openGLInfo, 0)
openGLInfo.GetVendor()
openGLInfo.GetVersion()
openGLInfo.GetRenderer()
openGLInfo.GetCapabilities()

```

On ParaView 5.7.X :

```
openGLInfo=servermanager.vtkPVServerImplementationRendering.vtkPVClientServerCoreRendering.vtkPVOpenGLInformation()
session=servermanager.vtkSMProxyManager.GetProxyManager().GetActiveSession()
session.GatherInformation(session.CLIENT, openGLInfo, 0)
openGLInfo.GetVendor()
openGLInfo.GetVersion()
openGLInfo.GetRenderer()
openGLInfo.GetCapabilities()

```

On ParaView 5.8.0 and newer

```
openGLInfo = GetOpenGLInformation()
openGLInfo.GetVendor()
openGLInfo.GetVersion()
openGLInfo.GetRenderer()
openGLInfo.GetCapabilities()
```
