From: Mathieu Malaterre on 1 Dec 2009 11:40 Hi there, I am getting confused. I cannot get xclock to run on a remote host from my ssh session: local $ ssh -X mpi0 remote $ xclock Error: Can't open display: :0.0 But I can still do: local $ ssh -Xf mpi0 xclock Could someone please remind me what is the difference, and what am I missing in the first scenario ?

Do you set DISPLAY variable in your login ? If you do you have to unset it (don't assign any value in any session config file).

Ah ! That was the trick. I can now move on to the next issue, how to get mpirun to do ssh -X .... (since ForwardX11 yes is not honored...)

Maybe the response is in mpi faq (search xterm): http://www.open-mpi.de/faq/?category=debugging I think you will have to disable -nolisten option in X see this bug for reference: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=539186 Regards, > > Thanks ! > -- > Mathieu > > > -- > To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org > with a subject of "unsubscribe".
