[SOLVED] Cpufreq not working

RaisedFist · 2009-01-11 08:00:11

I have a 64bit install and i'm trying to get cpufreq working. I had it working just fine in 32 bit before. I followed the steps in the wiki and I get this:

:: Setting cpufreq governing rules , cpu 0 1Error setting new values. Common errors:                                     [BUSY] 
- Do you have proper administration rights? (super-user?)
- Is the governor you requested available and modprobed?
- Trying to set an invalid policy?
- Trying to set a specific frequency, but userspace governor is not available,
   for example because of hardware which cannot be set to a specific frequency
   or because the userspace governor isn't loaded?
                                                                                                                         [DONE]

what could be the problem?

Later edit: I use ondemand governor

Well,

Is the governor you requested available and modprobed?

Wat does cpufreq-info say?

What doet lsmod |grep cpu say?

any more info needed?

everything looks good, you probably didn't have superuser rights when you issued the original command. this should work:

sudo cpufreq-set -g ondemand

to make it permanent you can put this in /etc/conf.d/cpufreq

#configuration for cpufreq control

# valid governors:
#  ondemand, performance, powersave,
#  conservative, userspace
governor="ondemand"

# valid suffixes: Hz, kHz (default), MHz, GHz, THz
min_freq="800MHz"
max_freq="1.80GHz"

Thanks a lot... the problem was in /etc/conf.d/cpufreq .. I had the default config - stupid me!
