def check_channel_x11_request(self, channel, single_connection, auth_protocol, auth_cookie, screen_number):
return False<EOL>
Determine if the client will be provided with an X11 session.  If this
method returns C{True}, X11 applications should be routed through new
SSH channels, using L{Transport.open_x11_channel}.

The default implementation always returns C{False}.

@param channel: the L{Channel} the X11 request arrived on
@type channel: L{Channel}
@param single_connection: C{True} if only a single X11 channel should
    be opened
@type single_connection: bool
@param auth_protocol: the protocol used for X11 authentication
@type auth_protocol: str
@param auth_cookie: the cookie used to authenticate to X11
@type auth_cookie: str
@param screen_number: the number of the X11 screen to connect to
@type screen_number: int
@return: C{True} if the X11 session was opened; C{False} if not
@rtype: bool
