Hi,
You don't need to export the display if you are using ssh...
ssh -Y <client>
of if that isn't working
ssh -X <client>
Then all you X stuff should work... (try issuing xterm on the connected target)
This does require you to have an X compatible desktop that you are running from. If you are running from Windows you need to get a X-server...

"from remote" is not exactly a technical description of your problem :-)
are you looking for a way to tunnel a X session through ssh or are
you trying to start a remote x program ?
in general you have to:
1) find out the names or IP addresses of "client" and "server" (see above)
2) on client:
- set $DISPLAY variable to server - client needs to know where to send output
(if you don't know how to set a variable just ask)
- then start your program
3) on server:
- allow client to connect - usually using the "xhost +name_of_client" command
sample session:
server name: asterix
client name: obelix
--------------------------
don@asterix > echo $DISPLAY ### show server name
asterix:0.0
don@asterix > xhost +obelix $DISPLAY ### allow obelix to connect
obelix being added to access control list
don@asterix > ping -c 5 obelix ### verify network connection
