To take this on topic... What about including a wealth of CPU
frequency scaling tools in edgy? While on gentoo I enjoyed quite
considerable power over my CPU, ubuntu doesn't give you the same. I'm
thinking mainly for laptops here. Noone wants to be running their
notebook at full power and getting all the heat that comes off it.
Since i've found you can actually run a machine rather well at 300mhz
(powersave governor for cpufrequtils), it might not be a bad idea to
What would be even better is if the user was allowed to control the
governor etc., albeit in a user friendly way.
