[Paraview] GNOME is hanging with co-processing ...

Fri Nov 4 10:02:43 EDT 2016

Hi Andy,

I updated driver and install PV successfully. As you point out, the 
recent driver solves the problem. By the way, i installed the 
co-processing code with PV with EGL support and now it runs without any 
problem and produces desired png files. The only minor problem is that 
the result png files do not have axis titles and axis labels. There 
could be a bug related with co-processing.

Thanks for your help and suggestions,
Regards,
