This behavior could be consistent with having the X server started by a 
different user than the one connecting later.  Note that when user fubar 
starts (owns) the X session, not even the user root can connect to it (not 
without resorting to trickery at least).  So, be sure you start the X server 
by the same account throughout.

But I think in that case the errormessage is slightly different:
unable to open display ""  is what I see here.

You could test to see if this would make any difference: adding the command 
'xhost +' in between export DISPLAY=:1 and the rest.  However, again, xhost 
must be run by the user owning the X session, otherwise it will just return a 
failure.  Please note that running 'xhost +' is NOT secure, it will open up 
your X session for everybody.  So use this only in a trusted environment !
