[ferret_users] Problem with plot display from HPC

["Akash. S" <akash013akash@xxxxxxxxx>]

Dear Ferret users,

I was trying Ferret on HPC server remotely from Ubuntu platform. While trying to plot, the image not displaying and showing the following error message.

But, when I tried the same thing through windows OS using PuTTy and Xming, it worked fine and gave me plots. So, why this problem happening with the Ubuntu? Can anybody give a solution for this issue? 

Any help is appreciated. 

Thanking You
