Hi, Power top is not intended to be used as a tuner, it is used as a analysis tools. If you find that the tunings are desired, you should work with the distribution to have them included, or make the necessary changes locally yourself. -----Original Message----- From: PowerTop [mailto:powertop-bounces@lists.01.org<powertop-bounces@lists.01.org>] On Behalf Of thibaut bethune Sent: Wednesday, January 22, 2014 3:16 AM To: powertop Subject: [Powertop] Settings modified from Powertop are not persistent Hi, I'm using Powertop with root privilege on Debian GNU/Linux 64 bits with my Core i3-3225.
