Well with "direct login" your shell is a child of init, hence:

if [ "$PPID" -eq "1" ]; then
echo yep
else
echo nope
fi

However this catches any sub-shell (even if "-l" such as Xterm) as not a
direct login shell. If you only want to differentiate between "su" or not,
maybe something like:

TTY=`tty`
if [ "`ls -l "$TTY" |awk '{print $3}'`" == "$USER" ]; then
echo nope
else
echo yep
fi
