Change default cpufreq governer to ondemand? [solved]

[beerisgoodmate]

I have a Dell m70 laptop with a pentium M processor.

I can happily change the cpu governor using eg:
cpufreq-set -g ondemand

But Whenever I reboot my laptop it is reset set to userspace, with the frequency set to 2GHz. This gives terrible battery life and means the fans are often noisy.

This is how my kernel is configured:

Code: Select all

[*] CPU Frequency scaling                       
[ ]   Enable CPUfreq debugging                                         
<*>   CPU frequency translation statistics                             
[ ]     CPU frequency translation statistics details                   
      Default CPUFreq governor (userspace)  --->                       
<*>   'performance' governor                                           
<*>   'powersave' governor                                             
---   'userspace' governor for userspace frequency scaling             
<*>   'ondemand' cpufreq policy governor                               
 <*>   'conservative' cpufreq governor

under default governor, I can only choose between userspace and performance.

Is there away to set default to ondemand or conservative?

using gentoo-sources-2.6.18

In cpufrequtils you have relevant config file (edit /etc/conf.d/cpufrequtils), then rc-update add cpufrequtils boot.
Or you can add "echo "ondemand" >> /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor" to local.start file.

great thanks, quickest solve I have ever had.

supprised I couldn't find such a simple solution on the forums, I had already edited the config file but hadn't added it boot.
