cpu-freq utils

Hi there,

Hope this is the right place to post this question....

I'm using Debian Wheezy with GNOME Shell at work and a got use to a little extension to set the cpu governor.
Is there something like that in openbox or does anybody know a good other way? to quickly modify the cpu governor?

Thankfull for any suggestions..

Re: cpu-freq utils

Well, bind icons in a dock or entries in a menu to a script that sets the frequency using the cpufrequtils, or use the terminal like I do it:

I wrote this Bash completion for cpufreq-set (from the cpufrequtils package): https://github.com/2ion/scripts/blob/ma … pletion.sh. It will auto-detect and complete the frequency scaling steps of your CPU and the available governors to I just enter 'cpufreq-set -u 16*tab*' and it will complete to 'cpufreq-set -u 1650000' meaning "set the upper frequency bound to 1.65Ghz". Same for the -g (governor flag) and others. Just read the script ;D

Note that when you use the cpufreq-* commands for setting something, they need to be run as root. I use the following entry in /etc/sudoers to allow launching them passwordless with sudo:

$myusername ALL = NOPASSWD: /usr/bin/cpufreq-set

Alternatively, you could make the binary SUID but personally, I wouldn't advise that.

...i'd like to add: you could hack yourself a quick script to toggle your most-used frequencies, and add it to tint2, so you have a "button".
conky would give feedback about the current frquency.
the most important bit is editing /etc/sudoers as mentioned above!

Use package https://packages.debian.org/cpufrequtils . You can configure it in /etc/default/cpufrequtils . I think cpufreq-set from the same package is not persistent. Use "sudo -s" to change to root or the sudoers-alternative.

True that it's not persistent, but neither is the defaults file, since at boot time the settings will be re-set to the specified values, unless you use a configuration script that uses both the CLI command for setting the frequency at run time and rewrite the configuration script for setting the governor at boot time.

Re: cpu-freq utils

Thanks for all the suggestions!

I think i will make a script and add it to the menu.

I googled for a while but could not find a solution to but a button into tint2, does anybody know how, just out of curiosity.

Search for tint2 launcher. You may also be able to modify this method: Simple "Start" menu button for tint2

(it's called "Launcher", not "Button")
