Con ssh e' bene non settare DISPLAY.
Da man ssh:
X11 and TCP forwarding
If the ForwardX11 variable is set to ``yes'' (or, see the description
of
the -X and -x options described later) and the user is using X11 (the
DISPLAY environment variable is set), the connection to the X11 display
is automatically forwarded to the remote side in such a way that any
X11
programs started from the shell (or command) will go through the
encrypt
ed channel, and the connection to the real X server will be made from
the
local machine. The user should not manually set DISPLAY. Forwarding of
X11 connections can be configured on the command line or in
configuration
files.
The DISPLAY value set by ssh will point to the server machine, but with
a
display number greater than zero. This is normal, and happens because
ssh creates a ``proxy'' X server on the server machine for forwarding
the
connections over the encrypted channel.
ssh will also automatically set up Xauthority data on the server
machine.
For this purpose, it will generate a random authorization cookie, store
it in Xauthority on the server, and verify that any forwarded
connections
carry this cookie and replace it by the real cookie when the connection
is opened. The real authentication cookie is never sent to the server
machine (and no cookies are sent in the plain).
If the user is using an authentication agent, the connection to the
agent
is automatically forwarded to the remote side unless disabled on the
com
mand line or in a configuration file.
Forwarding of arbitrary TCP/IP connections over the secure channel can
be
specified either on the command line or in a configuration file. One
possible application of TCP/IP forwarding is a secure connection to an
electronic purse; another is going through firewalls.
