If you have an X display running already, changing ssh's display offset to zero 
won't work (IIRC).
1) Set X11DisplayOffset to 10 on the server.
2) restart sshd (/etc/init.d/ssh restart or something similar)
3) SSH into the server with the -X option (ssh -X example.org)
4) run 'export DISPLAY=localhost:10.0'
5) evince

If that doesn't work, it may be an xauth thing, try substituting ssh -Y for ssh 
-X in step 3 and try again.


I'd not paid attention to what you wrote... setting display like 
'display=rem...@somedomain' won't work... you need a hostname (i.e. that @ sign 
is out of place). Secondly, the remote.somedomain computer must have X11 
running and remote access allowed (so, DISPLAY=remote.example.org:0 if you have 
an X display 0 running on remote.example.org), will launch X applications on 
remote's display 0.
