Switch from powernowd to kernel CPU frequency scaling?
 

Hello :)

I'm thinking of switching from powernowd to kernel CPU frequency scaling and would like LQ's comments; is it a good idea?

Reasons for making the change are

• One less init script to run at boot.
• The "CPU frequency scaling monitor" applet only ever shows 100% and 52%. If the information is correct it cannot mean optimal power saving.
• Better mechanisms are now available. Powernowd development stopped in Jan 08 with the maintainer saying "the 'ondemand' kernel governor seems to be the way moving forward".
• Some good looking HOWTOs, best found so far http://www.pantz.org/software/cpufre...eqonlinux.html.

The system is ubuntu 8.04.2 with kernel 2.6.24-24-generic.

Best
