[solved] who command doesn't show X server session

Question

Hi there,
shouldn't the `who` command show all logged in user sessions, including my X server session?
However, who only shows my tty1 session:
[orschiro@thinkpad]$ who
orschiro tty1 2013-10-25 17:01
What is the output of who on your system?

Answer 1

Alright. The point is, what do I need to do in order that who shows my X session?
I tried export DISPLAY=:0 but this doesn't add :0 to the who command listing.
The reason I am asking is that I want to use the following dispatcher script which queries for :0, assuming that who shows the display variable.
#!/bin/sh
INTERFACE=$1 # The interface which is brought up or down
STATUS=$2 # The new state of the interface
case "$STATUS" in
up) # $INTERFACE is up
USERS=$(ps -o user --no-headers -C dropbox)
killall dropbox
for user in $USERS; do
su -c "DISPLAY=$(who | sed -e "/$user/! d;/pts/d;s/^.*[^0-9]\\(:[0-9.]\\+\\).*$/\\1/p;d" | head -n1) dropboxd &" $user
done
down) # $INTERFACE is down
esac
