[Paraview] pvserver : cannot connect to X server

[Paul Edwards]

Hi Utkarsh,

The X display is being opened when the QApplication is created in
vtkQtInitialization constructor.  You added this call to vtkSMApplication
last month although the code is inside ifdefs for VTK_USE_QVTK.  I couldn't
see any cmake build option for this (unless it is VTK_USE_QVTK_QTOPENGL).

My current workaround is just to remove these calls and it seems to work....
- but I'm guessing you put it in there for a reason ;)

Regards,
Paul
