[DAP <875817@xxxxxxxxxxxxxxxxxx>]

I logged into the pseudo-terminal (tty2) locally by ctl-alt-F2 switching away from the login screen, so I was locally logged in, and "LightDM" still showed up.
ck-list-sessions is just not sufficient to distinguish the possible cases of someone logged in vs no one logged in.

If we are going to convert this to a wish list, I'd rather have cron updated so that it takes control of the wake timer and handles the waking and auto-shutdown itself.
I would think that there are many applications besides just MythTV where it would be useful to have a computer that wakes to run a scheduled task, and shuts itself down when there is no one using the computer, and no scheduled tasks in the near future.

This does not mean I think that a reliable way to determine if a user is
logged in is not necessary, in fact it would be required to properly
implement an updated chron tool.

Title:
  who -q no longer counts gui users

Status in “mythtv” package in Ubuntu:
  New

Bug description:
  The "checklogin.sh" script on this page: http://www.mythtv.org/wiki/ACPI_Wakeup uses "who -q" to determine if a user is logged in to prevent MythTV from shutting down the computer when a user is using the computer.
  On 11.04 this worked fine.
  On 11.10, my system shuts down 10 minutes after booting unless I open a terminal window.
  On opening a terminal window and running "who -q" I get:
  $ who -q
  dpeale
  # users=1
  I used to get "users=2". The gui user is not counted anymore.
  This is true of both Unity and Gnome GUIs

  The 'w' command also has the same bug (I've never been able to figure
  out what package that comes from). It also has another bug. If you use
  one of the ctl-alt-Fx screens, login, and then logout, it continues to
  count that screen as logged in.
