I realise this is quite an old post, but its still ranking highly on google results and getting comments, so….

Do you think you could update the content to reflect the correct way to achieve this?

To do this correctly the following steps are involved

1) Create a new group, say cpuadmin
2) edit /etc/cpufreqd.conf and find the lines like
#enable_remote=1
#remote_group=root

uncomment these lines, and replace
remote_group=root
with the group you created, ie
remote_group=cpuadmin
3) add any users you want to have control over cpu scaling to the group cpuadmin
usermod -a -G cpuadmin
once user has logged out and back in, settings will apply to them

Hmm…I’m not sure if this works for me. It would appreat the script is executed when I shut down, not when I log in.

Also another question: the script I want to roon requires root access. Do I need to do anything sepcial?

PU frequency scaling had, by default, its behaviour locked to automatic choosing of CPU frequency. All regarding setting unnecessary superuser powers to yet another application. Quoting: “And why should a normal user be able to change the CPU speed in the first place? The automatic CPU speed works well enough for the majority of users, and control freaks can always use sudo to manually set the speed, or deliberately shoot themselves in the foot by making the binary suid root”. And that’s the trick. Issue a sudo dpkg-reconfigure gnome-applets and answer “Yes” to the question regarding setting the suid of the cpufreq-selector executable. Now, when I left click the CPU Frequency Monitor Applet, I’m able to choose the behaviour (powersave, max. performance, etc) and/or the processor speed.

If you check the preferences for the applet, you can enable “Governors” and “Frequencies” for control. Try setting the frequency using the frequency menu after you enable it. It will then sta y at one frequencies.

CPU Frequency Scaling Monitor simply sucks. Version 2.28 is not able to do the most simple thing on Earth: changing all CPU speed by one click (I mean, a single “all CPU” entry should be put in the drop-down menu).
Now that every CPU has at least 2 cores, I wonder how people didn’t find it frustrating to have 2 of the same applet on their desktop, not to mention quad core CPUs.
