Why do you need to change it? The actual display number is determined
by the X11DisplayOffset setting in the sshd_config file. sshd
allocates display numbers for X proxies starting at that value. The
default is 10, which is enough to ensure that the numbers won't
conflict with real X displays on any normal system.

Note that if you change DISPLAY manually (via "export"), you may also
need to update the X authentication credentials with xauth.

By default sshd will only accept connections on the loopback address
(127.0.0.1). If you try to connect to coyote:10, the connection will
probably use another address (i.e. the address assigned to the
physical network adapter) and be refused. You can change this
behaviour via X11UseLocalhost in sshd_config, but in the absence of
some form of firewall, that will allow other hosts on the network to
connect to the X proxy.
