[lug] DISPLAY variable.

[John Starkey]

I'm installing Oracle and it's looking for the DISPLAY variable. Never
even heard of this. 

The install guide says to enter:

DISPLAY=<workstation>:0,0
export DISPLAY

then if I have any problems I should enter:

xhost +<workstation>

Can anyone tell me what the variables are? <workstation> seems pretty
self-explanatory, the error message says:

can't connect to X11 window server using <workstation>:0,0 as the valuable
of the DISPLAY variable

So, since I know both my IP and my /etc/host entry I'd have to say it's
the :0,0 part that's causing it.

TIA,

John
