[Paraview-developers] detecting X display

[Favre Jean]

After checking out the latest changes, my server-side rendering on the Cray does not work anymore because the DISPLAY is not correctly identified.

Error message is:

"Display is not accessible on the server side.
Remote rendering will be disabled."

I reverted to a tag just before the fix to detect X

 ad33f7548abf4b0b643e2ed15dd9ba1f8690c04f

and got everything working again.

P.S. I use hardware-rendering and specifically start X servers and set DISPLAYs to :0 for every job.
