Please read the "Question Guidelines" link in my posting signature. Doing basic research first is a good thing before posting; your error is most likely caused by either not SSH'ing with the "-x" flag (for X forwarding), or you have X forwarding disabled in your sshd_config file. Make sure its set to

Code:

"X11Forwarding Yes"

..in that file.

I already set the x11 forwarding as yes.Could you please help me out on this.

I did explain it before; read the man page on SSH, and as suggested before, read the "Question Guidelines" link in my posting signature, and do basic research first, before posting.

As said, "your error is most likely caused by either not SSH'ing with the "-x" flag (for X forwarding)". So "ssh -x"
