I am trying to export DISPLAY to my workstation, but i cant. i keep getting DISPLAY=hostname is not an identifier any suggestions would be greatly appreciated

Nah, the "old-fashioned" (bourne shell, I believe)
DISPLAY=xxx:0.0; export DISPLAY

is the same as the csh's
setenv DISPLAY hostname:0.0

But I tried it anyway, just for giggles. Same result when trying to open anything like dtpad:
error: Xlib: connection to "hostname:0.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
Error: Can't open display: hostname:0.0

SirLancelot:

If you have another host that does have a graphics card, type "xhost hostname-of-serial-display-server" on it.

On the server with the serial display type DISPLAY=graphics-hostname";export DISPLAY. Then you will be able to type "xhost new-hostname" on the server with out the graphics card.

Try it.
