What are you using as an ssh terminal emulator ? PuTTY ?

what the first response says, i.e.,

export DISPLAY = /0.0

is the thing you ABSOLUTELY should not do. if you are going to tunnel X-sessions thru ssh. setting of the DISPLAY variable should be left to the communication between sshd on your server and termianl emulator you are using.

if you are using putty, in your putty profile to connect to this server, go to the

connection --> ssh --> X11

on the left side navigation. On this screen you need to put a check-mark next to "Enable X11 forwarding" and select "MIT-Magic-Cookie-1" radio button. "X Display Location" should be "localhost:0" by default. If not, change it to this string.

And you should be set.

One more observation..
While logging i am getting follwoing error

/usr/bin/X11/xauth: error in locking authority file /home/opssup/.Xauthority

Is there any relation with this X11 dispaly issue.

I am not 100% sure why this happens but remedy is :

rm /home/opssup/.Xauthority # if exists
touch /home/opssup/.Xauthority

this should fix your woes
