Topic: cpu-scaling

Hi everyone, I'm reading this forum from 3 days ago finding every kind of solution to my confguration box problem big_smile... untill now. sad
I've to say I fall in love with #! + xfce! cool
I've installed the cpufreqd (I dont remember if it's the real name) package and the command
sudo cpufreq-set -g ondemand
seems to work but the cpu freq is always 2.2GHz even on startup!

$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies 
2200000 2000000 1800000 1000000 

$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors 
userspace powersave conservative ondemand performance

$ cat /etc/modules 
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
# Parameters can be specified after the module name.

#firewire-sbp2
loop

powernow_k8
acpi-cpufreq
cpufreq_conservative
cpufreq_ondemand
cpufreq_powersave
cpufreq_userspace

I hope this information can help to find a solution because the noise of the fan is gonna drive me crazy! yikes

Re: cpu-scaling

I had a post a little while back pertaining to CPU scaling. There might be something here that you can use to solve your problem:

Also, I have an ATI graphics card in my laptop (HD 4650) and at one point in time was having problems with CPU scaling being "stuck" as you described. I solved it in my situation by installing the proprietary ATI drivers. After they were installed the CPU scaling, ondemand, worked like a charm. I hope this helps.

Re: cpu-scaling

Hi,

I had the same problem and the solution that helped me was to open my laptop and remove the dust on the fan.....
Thanks to this, t° decreased of few degrees and fan and cpu were now working normally.
There was not so many dust, but just enough to disturb cooling and then influence cpu scaling...

Maybe it won t solve your problem but for me it was the solution.... big_smile

Re: cpu-scaling

The installation of the official ati driver went wrong so I removed to come back to the open ones that work perfectly.
However because of I had a config file I done months ago 4 my nb, I recompiled the kernel 2.6.34 and I've to say that nb is more quiet now.

I dont know what to think/say.
