[Paraview] mpirun pvserver: bad X server connection.

[Berk Geveci]

You probably have to set DISPLAY to :0 in your .XXXrc (.bashrc, .cshrc,
.kshrc, .zshenv) so that it is set during a non-interactive remote session.
In the next version of ParaView (2.6), it will be possible to set the
display in a configuration file.
