Remember to restart sshd after making changes to the config files.
I have the systems names in each of the computers' /etc/hosts files.
My session is
xhost computer1
This is not necessary.
ssh myaccount/computer1
As Scot mentioned, use ssh -Y or ssh -X. See "man ssh" to see why - Y is
preferred.
export DISPLAY=computer2:0
This step is not necessary since the X11 tunnelling should be taken care
of for you.
Do "echo $DISPLAY" to see what it is set to.

Although /etc/ssh/sshd_config had been configured previously with
X11Forwarding yes
I restarted sshd and network on both computers.
I tried
ssh -Y user@computer1
but the current openssh on the systems did not support the "Y" option.
I tried ssh -x user@computer1
export DISPLAY=computer2:0
"printenv DISPLAY" comes back with computer2:0 and the error message
when I try graphic software across the network says that it can't display
on computer2:0.
If you are using X forwarding with ssh, you don't need to use "xhost" on
the server end and you don't need to set $DISPLAY at the client end -
ssh does all of that for you transparently.
Try:
$ ssh -X user@computer1
(that's -X, not -x)
Then try running your graphic software without setting $DISPLAY.
