So it's ok that if I run powertop then it suggest me to disable xy, etc., but after I exit powertop, reboot the pc, and start it again[powertop], it brings up the same tips again! So how can I permanently save the suggestions of powertop?

@Oli Can we please reopen this question? Due to edits to the linked question, this question is not a duplicate anymore. Especially not an exact duplicate. I'm facing this problem as well and need to find a solution soon. –  user24668 May 11 '12 at 12:21

Can you tell us what exactly the "stuff" it want's you to do is, so we can see any problems. For example, a specific command, or set of commands it want's run. How your running it, etc. Can we perhaps look at just one change it want you to make. It's very hard to tell why it's randomly not working without more data. –  coteyr Nov 6 '12 at 16:45

Quick answer :

You just need to save them in /etc/rc.local


Detailed answer

1) In a terminal run :

sudo powertop --html=powertop.html

2) Step 1 generates a html file in your home directory. Click on that file so that it opens in your internet browser.

3) In the browser, go to "Tuning" tab. It gives all the tunings you have to tweak (on the left), and the commands that are implementing them (on the right).

4) Save these commands in /etc/rc.local

To do that, in a terminal, run :

gksu gedit /etc/rc.local

Write the commands before the line that reads "exit 0", and save the file.

This doesn't exactly save your powertop settings, but it does come with its own defaults which enable almost every powertop setting. It's called laptop-mode-tools.

Just run "sudo apt-get install laptop-mode-tools" and run powertop, see if you like it. This also enables you to edit the settings, which in turn, edit the powertop settings.

You can edit the settings by typing in "sudo gedit /etc/laptop-mode/laptop-mode.conf" Maybe someone else knows how to save the settings "specifically" from powertop.

laptop-mode-tools was replaced by pm-utils-powersave-policy in 2010, and may have since been replaced by something else. I don't think it's useful in current ubuntu releases. –  ImaginaryRobots Nov 7 '12 at 17:18
    
hmmm very interesting. I use Ubuntu 12.10 and I con confirm laptop-mode-tools works just great and actually does function/shutdown things such as usb ports for a specific period of inactivity. However I will checkout this pm-utils. –  Leealis Nov 8 '12 at 21:13
    
does installing laptop-mode-utils still cause other things to get uninstalled? It's possible that it got un-replaced or something... –  ImaginaryRobots Nov 8 '12 at 21:59
