[OpenFOAM] ParaFoam over SSH - cannot connect to X server

uli · July 17, 2012, 18:03

hi all

Running a simulation over ssh works, but when I type "paraFoam" it gives me

Code:

cannot connect to X server

I use opensuse 11.4, the server I am connected to has ubuntu.

I also set up a connection with XMing and Putty on Windows, there it works.

Any suggestions?

thanks,
Uli

What command are you running to connect to your server? First thing I would make sure is that X forwarding is allowed. You have the -X/-Y option in your command to enable X forwarding?

hi Marco, thanks for your reply.

Sorry, my bad. I forgot the -X.

But it gives me another error:

Code:

ssh -X myname@ipadress

and when I run "paraFoam" in the case-directory the "welcome" Window of ParaView opens but after a few seconds I get

Code:

created temporary 'cavity.OpenFOAM'
Segmentation fault (core dumped)

thanks
Uli

It seems like X forwarding is working as you got the welcome screen. Does this happen with both -X and -Y options?

Greetings to all!

This comes to mind:

Setting the environment variable via the command below worked for me.

export LIBGL_ALWAYS_INDIRECT=y

I tried this after reading http://ubuntuforums.org/showthread.php?t=1098568

Hope this helps anyone else in the same boat.
