Bug description:
Until now, I've been using good old gdm-2.20.11 and wanted to switch
to lightdm-1.12.1. If you list users logged in via the 'w' or 'who'
command, it shows you who is logged in and what they are doing.
Especially, on which tty. Example:
USER TTY LOGIN@ IDLE JCPU PCPU WHAT
user tty9 03Oct14 16days 1:52m 0.01s /bin/sh /etc/xdg/xfce4/xinitrc
-- /etc/X11/xinit/xserverrc
Also, 'who' gives this information:
user tty9 Oct 3 22:34 (:20)
However, lightdm does not follow that tradition. Instead, it prints :0
instead of the actual tty, and something weird for other values (like
?xdm? instead of the idle value etc.)
'w':
USER TTY LOGIN@ IDLE JCPU PCPU WHAT
user :0 19:50 ?xdm? 23.82s 0.01s /bin/sh /etc/xdg/xfce4/xinitrc
-- /etc/X11/xinit/xserverrc
Note: :0 is not tty, it is DISPLAY env.
'who':
user :0 2014-10-12 19:50 (:0)
The same for this one. I wonder, is this a bug (to me it seems so,
because for every other program the correct values are reported)?
It is a problem for me, because I have written scripts for automation
etc. that parse w and who output to determine which tty is in use by
which DISPLAY.
