You're running an X server on the desktop computer, and then using
cygwin's SSH client to forward X11 when you connect to the remote
host.  This is how $DISPLAY is being defined.  Also, your X11 server
will need to support GLX for the remote X11 applications to be able to
support it.

I suggest looking at your desktop computers and figure out why one of
them doesn't support GLX.  Try to take the SSH connection out of the
loop, since that's most likely unrelated.
