Darn. I see that you use xdm, that might explain the difference. No clue
WHY this makes things different, but apparently it does. It's
interesting to note that your FROM column was dipslayed in the Office
column by finger, and I was getting my display from there as well.
Anyway, I can simply check both columns:
getXuser() {
w -hs | while read -r THIS_USER THIS_TTY THIS_FROM DUMMY_REMAINDER; do
if [ "$THIS_TTY" = "$displaynum" -o "$THIS_FROM" =
"$displaynum" ] ; then
user=$THIS_USER
break
fi
done
if [ x"$user" = x"" ]; then
startx=`pgrep -n startx`
if [ x"$startx" != x"" ]; then
user=`ps -o user --no-headers $startx`
fi
fi
if [ x"$user" != x"" ]; then
userhome=`getent passwd $user | cut -d: -f6`
export XAUTHORITY=$userhome/.Xauthority
else
export XAUTHORITY=""
fi
export XUSER=$user
}
Does this version work for you?
Cheers,
Bart
