Getting rid of "Cannot open display" message

[Amit Dor-Shifer]

Hi all.

I'm using ssh to execute a command on a server. When the remote server
has an X server running, I get a/m message written to standard error.

amit0 ~ # ssh localhost echo bla
Cannot open display "default display"
Cannot open display "default display"
bla

Appending the '-x' parameter, as suggested, doesn't seem to help:

amit0 ~ # ssh -x localhost echo bla
Cannot open display "default display"
Cannot open display "default display"
bla


I want to disable whatever's causing this message. I don't need X
running over the connection.

How do I get rid of this message?

ssh version:
amit0 ~ # ssh -V
OpenSSH_5.2p1, OpenSSL 0.9.8k 25 Mar 2009

10x,

"-X" capitalize it.

look into your ~/.profile and /etc/profile.
You might be running an X client.

You must have something in one of your shell's startup scripts that is
trying to access an X display. Adding a "set -x" at the top of your scripts
will force each line to be printed as it is run, which should help you track
down the offending commands.
