Scaling CPU Frequency

**es926** · October 8th, 2008

Hello,

I installed cpufreq and gave suid root to the gnome applet for it so that I can easily control it. Something keeps changing the allowed range for frequencies every time I restart, plug in the power cord, or unplug it though. What program is changing these settings? I would really like to just control it myself and it gets annoying having to type sudo cpufreq-set -d ".8GHz" -u "2.4GHz" over and over.

Thanks

It's probably the cpufreqd (daemon). Try removing it (through Synaptic or apt-get remove) and seeing if the scaling functions properly. If you have to reinstall it, you can configure it by editing /etc/cpufreqd.conf

This always works for me:

Code:

sudo chmod +s /usr/bin/cpufreq-selector

That permits you to control from the tray applet.

Thanks for that fjgaude, I wondered what the problem was.

Thank you for your post! This worked like a charm for my HP tx1320us, and I'm sure it could work for other people as well. Now I can switch from Userspace, to Ondemand as needed...this is great! Thanks again.
