The machine wide settings are in /etc/ssh/ssh_config
if you want to change the behaviour of ssh for yourself
copy this file to $HOME/.ssh/ssh_config and change

    ForwardX11 no

to

    ForwardX11 yes

If you want to change it permanently only for a specific domain insert

    Host *.yourdomain.org
      ForwardX11 yes

Your privat ssh_config in $HOME/.ssh/ will overwrite the settings
in /etc/ssh/ssh_config as long as the SSH server on the remote machine
allows it.
