cpufreq problems.

[melodie]

Well I guess my laptop will continue to run at full blast cause noones knows how to fix this.  That sux.   

Hi,

I have been told some cpu nowadays have it all set inside, and trying to manage it logically is not possible. I suggest you look at the bios settings, and check if there is any update available for it.

I suppose you also tried the command lines which have been suggested to add in the /etc/rc.local file ?

Have you told us what brand and model machine is your's ?

[redjama]

yea I have tried everything posted in here.  I have a post in the laptop section also and nothing has fixed this.  its strange cause in Windows I don't have this problem.  I hate Windows and almost refuse to use it but at the same time my lap top is wide open and eventually its gonna over heat and take a dump on me, I need to fix this.

[AndrzejL]

I guess I will use it. I like my laptop to use 100% of it's power but... heat is mighty

I ran cpufreq-set -g ondemand as root and it lowered the temp about 10 degrees Celsius.

I have tried this setting and it does absolutely nothing.

As you can see it changes nothing.  The only governor thats chenges the settings is the powersave one and for some reason it lags the comp down.

[root@localhost brian]#See!!

[AndrzejL]

Powersave works for You. Good.

Ondemand is not being modprobed... Weird.

Try

Code: [Select]

modprobe cpufreq_ondemand
as root. See what this gives You.

Andy

[redjama]

yes the powersave works but lags the comp down and i cant seem to get it to load at boot up.  Ill try the modrobe ondemand, i think i already did earlier but ill try again.

[redjama]

Code: [Select]

root@localhost brian]# modprobe cpufreq_ondemand
[root@localhost brian]# cpufreq-set -g ondemand

Still ending with the same result

I would also need some more info:

Did You tried modprobing any other cpu driver?

What kernel are You running?

The available cpu drivers are:

Also... do You have powernowd apmd acpi acpid installed?

Also - are You fully upgraded?

Also what version are You running?

Also did You tried booting up from the PCLinuxOS 2011.6 test 2 livecd and see what module is used for Your CPU and is ondemand working on the LiveCD?

Regards.

No i didnt try to modprobe another cpu driver.  I am fully updated.  Im using the latest kernel available 2.6.38.8.  I just found out that the p4-clockmod driver only supports the performance and powersave governors. Had all installed but the powernowd

This is why You could not used ondemand correct. This is why i was asking did You tried modprobing any other cpu driver.

How do i modprobe another driver???

[redjama]

and once i do the moprobe how do i get it to load al the time and not the p4-clockmod driver??

[AndrzejL]

Modprobe just the name of it.

The path will be:

/lib/modules/YourKernel/kernel/arch/x86/kernel/cpu/cpufreq/

Keep in mind that not to many of them will actually work with Your CPU.

You modprobe them by running

Code: [Select]

modprobe nameofthemodulewithouttheextension
as root lets say

Code: [Select]

modprobe p4-clockmod
If any of them works without errors - (also test by using cpufreq-info) edit the /etc/modprobe.preload.d/cpufreq file and replace p4-clockmod entry there with the other module's name.

Chances are p4-clockmod is the only one for Your CPU then You must stick to it and live with 100% or lag...

Regards.
