Change the script to be:
if tty -s; then
set . $(ps -o args -p $PPID)
case "$3" in
*telnet*) DISPLAY="$5";;
*rlogin*) DISPLAY="$8";;
*) DISPLAY="None";;
esac
DISPLAY="$DISPLAY:0"
if [ "$DISPLAY" = "None:0" ]
then
unset DISPLAY
else
export DISPLAY
fi
fi
the previous one had a "." in the line:
*) DISPLAY="None";;
which was a tab.
