Public bug reported:
Binary package hint: laptop-mode-tools
unmounting ath5k and mac80211 by issuing sudo rmmod ath5k and sudo rmmod
mac80211 reduces wattage consumption of laptop/netbooks. powertop shows
12.9w consumption while these modules are mounted and when I issue the
commands above powertop shows a gradual decrease in wattage up to 11.1
watts. can this be integrated in laptop-mode-tools? it would be nice if
laptop-mode-tools can automate this like unmount modules when not in use
for x seconds.
