SOLVED Power saving CPU frequency throttling working
« on: July 11, 2011, 02:10:23 AM »
I have been trying all sorts of things to try and get my CPU throttling working (I had it a while back but I think I re-installed) and had almost given up.
I tried one last time removing all power controlling stuff apart from that which would have removed KDEbase etc. Rebooted and added the software listed below and rebooted again.
I am running KDE upto date 4.6.5-1 and kernel 2.6.38.7-pclos1.bfs #1 SMP PREEMPT running on a Asus M4A78LT-M LE AMD 760G Socket AM3 quad core with Integrated ATI Radeon 3000 2 Gb RAM
For those of you wanting to save some energy here are the programs that worked for me
Installed software
acpid, libpowersave10, pm-fallback-policy, pm-utils, powersave
Widgets
I added system load viewer and that shows me it is working. I didn't have to do any setting up.
Hope this helps

Can you share a little more about which packages you removed?

Thanks for sharing this!
I had similar problem and have been searching for a solution to no avail. I even followed Tex' s instructions on PCLinuxOS Magazine (june 30) with no success. Reading your post I just checked to make sure the above listed packages are installed. I found two of these were not installed. I then installed those and rebooted. BINGO! All is working now.

I have also made the surprising discovery that not all repos contain the same files.
On a new install on different hardware I had the http://ftp.ch.debian.org/mirror/pclinuxos/apt/ repo and powersave was not in it.
I changed to the http://ftp.heanet.ie/pub/pclinuxos/apt/ repo and there it was.

Hi omskates, I removed any packages that referred to power. Sorry I cannot remember which ones they were.

Hi Marco07, glad I could help.

Thanks VTC, I was just wondering 'cause of some power issues of my own.  See thread: http://www.pclinuxos.com/forum/index.php/topic,94839.0.html  Glad things are better for you now :)

Hi omskates, have read the threads you mentioned. Are there any BIOS settings you can change to do with power management?
Is there an update (From some kind of testing repo) for any of the power stuff?

Thanks for your response.  For now turning off the acpi service and starting apmd improves things slightly but cpu still throttles up during charging and screen flickers, so it is still unacceptable.  I turned off notification for AC adapter plugging.  I'm really thinking this is hardware related as KDE keeps telling me my main battery is "broken".  I'll wait till replaced and then continue.  I'm placing this small dialog into my other thread as a quote, you can respond further there if you like since this was 'your' thread to start ;).
