Binary package hint: cpufreqd

Ubuntuforums thread : http://ubuntuforums.org/showthread.php?t=1098459

In Jaunty 9.04, a few days ago, it was noticed that the default CPU
frequency is now "Performance".  Before, it was set to "OnDemand".  This
can be changed back again on a per-session basis by clicking on the
CPUFreq applet (in gnome) and changing the setting to whatever is
desired, or changed permanently either by updating
"/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor" or using
"cpufreq-selector -g ondemand"

However, when using a laptop, this is not desirable default behaviour as
the effect on battery is obvious.  This setting should be "OnDemand" by
default.
