You also may need to use xhost to add the remote machine to
the access control list on your local machine; for example,
in your Cygwin shell:

   /usr/X11R6/bin/xhost +<linux_machine_name>

Some applications also don't seem to work with ssh -X or
ssh -Y. For those apps, you may need to explicitly export
the remote machine display to your local machine; for
example, from your Linux box:

   export DISPLAY=<cygwin_machine_name>:0.0
