Can't help with the KDE problem, but I've just started using Cygwin and 
have seen the above problem.  Actually, the DISPLAY setting was NOT a 
problem for me and I was wondering why so I looked into it and found out 
that it was being set in ~.bashrc (on the machine being logged into) by 
the code below:

# Smart way of setting the DISPLAY variable (from Hans) :)
if test -z "$DISPLAY" -a "$TERM" = "xterm" -a -x /usr/bin/who ; then
     WHOAMI="`/usr/bin/who am i`"
     _DISPLAY="`expr "$WHOAMI" : '.*(\([^\.][^\.]*\).*)'`:0.0"
     if [ "${_DISPLAY}" != ":0:0.0" -a "${_DISPLAY}" != " :0.0" \
          -a "${_DISPLAY}" != ":0.0" ]; then
         export DISPLAY="${_DISPLAY}";
     unset WHOAMI _DISPLAY

My distro is SuSE, and Hans sounds Germanic - so maybe this is not in 
Debian.  It does work however - setting DISPLAY correctly from local 
login or from a couple of remote logins.
