Hi Tormod,

Yes, it is the -x option.
This was fixed upstream already.

  Run pidof with the -x Script Mode switch. Thanks Matthijs Kooijman

  while debugging another issue, I noticed that the check for running lm-
polling
  daemons is not working.
  /usr/share/laptop-mode-tools/modules/battery-level-polling uses
  "pidof lm-polling-daemon" to see if the daemon is already running, but this
  does not work. The actual process is /bin/sh, which is running the
  lm-polling-daemon script. To make this work properly, pidof supports a -x
  option:

         -x Scripts too - this causes the program to also return process
                id’s of shells running the named scripts.

  When passing -x, laptop-mode stops spawning new on every restart (and
probably
  in other cases as well). It seems that the killall line used does work
  properly.
