Put the following lines into your .profile:
DISPLAY=your_display:0.0
export DISPLAY

Hi,

You do not need to specify the DISPLAY variable manually with the use of ssh 2.X.X and sshd 2.X.X.

When you login to the sshd2 server using your ssh2 client, the variable SSH2_CLIENT is automatically set. The values comprise of the quadruple "SSH2 client IP address", "SSH2 client TCP port used", "SSH2 server IP address", "SSH2 server TCP port used".

Thus, to set your DISPLAY variable automatically upon login in your startup script (eg. ~/.profile for sh, bash, ksh), add the following lines:

In ~/.profile (for sh, bash, ksh login shells),

export DISPLAY=`echo $SSH2_CLIENT|awk '{print $1}'`:0.0

In ~/.cshrc or ~/.login (for csh, tcsh shells),

setenv DISPLAY `echo $SSH2_CLIENT|awk '{print $1}'`:0.0

If you do not wish to use awk, you can use cut as well. Instead of awk '{print $1}', use "cut -d\ -f1" in its place.

Hope this helps. Regards.
