[opensuse] How do I control power management CPU frequency scaling in OpenSUSE 11.1?
My Laptop CPU frequency scales even when plugged into AC power and I'd like to disable that feature. How do I do that in OpenSUSE 11.1? The "Power Management" tool in "Control Center" only has options for the display and suspend settings, nothing for the CPU (It used to be there didn't it?). The CPU frequency widget in the toolbar also does not have an option to disable scaling. I know I can probably echo something to /proc but I'm looking for the desktop GUI way, not the command line.

Thanks for taking the time to reply but those links are useless. The information is all outdated and even what information is there does not mention anything about CPU frequency scaling (or "throttling", as it's called on one page). -- John Lange http://www.johnlange.ca On Wed, 2009-02-25 at 21:07 +0100, cagsm wrote:

you didnt look into the stuff in detail, and didnt look at powersave command at all. tux:~ # powersave -c DYNAMIC tux:~ # lscpu Architecture: i686 CPU(s): 2 Thread(s) per core: 1 Core(s) per socket: 2 CPU socket(s): 1 NUMA node(s): 1 Vendor ID: AuthenticAMD CPU family: 16 Model: 2 Stepping: 3 CPU MHz: 1400.000 Virtualization: AMD-V L1d cache: 64K L1i cache: 64K L2 cache: 512K L3 cache: 2048K tux:~ # powersave --help ...

how do you figure its useless? such big words....
Well, I apologize if you found that offencive, it does sound rather harsh. My question was how to do it via Yast (or some other GUI) in 11.1 since that used to be an option in OpenSUSE a few versions back and that isn't mentioned on that link anyplace that I could find.
powersave -f is exactly what you are looking for. it sets the cpu to maximum performance level, and prevents downgrading the frequency, and so on.
That appears to work on my machine so it's a good work-around. Thanks. There also appears to be: cpufreq-info cpufreq-selector cpufreq-set But I haven't played with those yet.

KPowerSave does indeed have a section for configuring the CPU frequence policy. Unless something is amiss along the way in detecting your hardware's capabilities and that section is incorrectly disabled, that's where you'd go. If it is disabled and you're sure your hardware has frequency scaling, then possibly something lower-level is messed up and KPowerSave doesn't think it can control CPU frequency. I have one machine with CPU frequency policy control running 10.3 and KPowersave offers me the pertinent controls and one, running 11.1 that does not have such capability and there KPowersave doesn't offer me those controls.

It does not work on my Compaq Presario Laptop either under 11.1 but did under 10.3 that uses an AMD Turion 64 bit CPU Yet another 11.1 bork if it was not for the fact that i am completely sick of redoing configs all the time i would go back to 10.3 and KDE 3.5.9 that just worked with no nonsense Pete. -- Opensuse 10.3 x86_64 (Linux is like a wigwam no Gates, no Windows, and an Apache inside.) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

You should. It has many health benefits (and that's really true, not a joke).

Yes but it goes a lot deeper than just PA KDE4 all sorts of things screwed up Permissions i run a usb 3G modem or should i say i did cus since i have had to reinstall 11.1 due to updates forcing me onto KDE 4.3 alpha stuff now it feruses point blanc to work and i am now begginig to get a little p****D off with it all now so it goes a lot deeper and it is about time the opensuse people got their collective butts into gear and started enforcing a few standards on the releases once again so that we at least stand a decent chance of being able to use the system instead of spending time fixing things that shoud be working from the ground up Pete . -- Opensuse 10.3 x86_64 (Linux is like a wigwam no Gates, no Windows, and an Apache inside.) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Thats simple as well improving it without breaking it completely like what it is now there will also always be some slight fopars somewhere but total screwups would be very happily "A.W.O.L"
