Well this didn't work either. Not sure what the ^ is for but the
problem has been solved a different way. I just used

echo $DISPLAY

with this I get

wsXXX.ltsp:0.0
on a terminal

or
:0.0
on the server

then I just use C++ to throw away anything after the :
So I either have the wsXXX.ltsp or nothing. However, (and this was the
problem before) you can't grep for nothing. So if it's nothing I
replace it with "xxxxxxxxxxxxxxxxxx" which will never match anything
in /etc/hosts (as I want).
Then I used
getent hosts | grep -w line | awk '{print $1}'
where line is either xxxxxxxxxxxxxx or wsXXX.ltsp. So it works perfect now.

Expect Fl_TT 0.31 VERY soon with much improved speed :)
