Erm, is this meant to ouput the results, and then exit?
It doesn't on my box, it seems to act exactly the same as powertop
without -d. powertop-1.7-3.fc7
What about Fedora-specific things powertop complains about, such as
Suggestion: Disable 'hal' from polling your cdrom with:
hal-disable-polling /dev/scd0 'hal' is the component that
window if you plug in a CD but disables SATA power saving from kicking
Disable the SE-Alert software by removing the 'setroubleshoot-server'
SE-Alert alerts you about SELinux policy violations, but also
has a bug that wakes it up 10 times per second.
Suggestion: enable AC97 powersave mode by executing the following
echo 1 > /sys/module/snd_ac97_codec/parameters/power_save
or by passing power_save=1 as module parameter.
