Title:
  acpi-support should use ck-list-sessions to determine active X display
  and X user

Status in “acpi-support” package in Ubuntu:
  New

Bug description:
  
  The acpi-support scripts use 'ps' and 'who' output to determine the current active X display and X user (in getXconsole and getXuser).  Currently, LightDM does not write to utmp so 'who' does not output the correct information breaking getXconsole and getXuser.  

  ConsoleKit properly maintains the state of the console and probably
  should be used instead.

  I've attached a patch that re-implements getXconsole and getXuser by
  calling ck-list-sessions.
