Problems with -eps_monitor_draw and mpiexec

[Tim Stitt]

Hi all,

I've finally got my parallel solver working in SLEPc. I want to monitor the 
eigenvalues and error tolerances graphically using -eps_monitor_draw. This 
works perfectly fine for the serial version of the code but when I test the 
parallel version I get the following errors from all nodes:

[1]PETSC ERROR: --------------------- Error 
Message ------------------------------------
[1]PETSC ERROR: Error in external library!
[1]PETSC ERROR: Unable to open display on localhost.localdomain:0.0
.  Make sure your COMPUTE NODES are authorized to connect
    to this X server and either your DISPLAY variable
    is set or you use the -display name option

FYI: I am testing these codes on a multi-core laptop so I am running mpiexec 
directly from the command-line. Without -eps_monitor_draw the code runs as 
aspected.

Just wondering if someone can hint at a fix so that I can get the graphical 
monitoring working in parallel. 

Regards,

Tim.
