Nope - you need to use the correct file generated by the running X
secession. Note, this is taken care of automaticly for you when you
run "su -" in a terminal in the running X secession. It is also
taken care of by ssh when you used ssh -Y to connect to a remote box
from an xterm on your machine. Where you run into problems is when
you log in at the cli as root, and then try and run a program that
requires an X display, or when you ssh to another machine without X
forwarding enabled.

Oh yes, chances are, the correct cookie file is in the /tmp
directory somewhere.
