Power management

Post by nick »

Hi
Copied from synaptic:

Powernowd

control cpu speed and voltage using 2.6 kernel interface
This simple client controls CPU speed and voltage using the sysfs interface
to the CPUFreq driver in v2.6 Linux kernels. It does not depend on APM or
ACPI, and it doesn't try to do anything other than control the CPU.

The name is somewhat misleading, as any CPUfreq capable processor will work,
not just those from AMD. However, it works better on CPUs that support more
than two speed steps, like those with AMD's PowerNow! or Intel's Pentium M
series.

This daemon is less complicated than cpufreqd or cpudyn, at the cost of
absolutely depending on a 2.6 kernel with the userspace governor and sysfs
support enabled.
Not sure is it is installed by default,(I always install KDE), but it is in my 3 AMD boxes, and for instance my 3.4ghz always sits at 1ghz when just surfing etc, then pulls up to fullspeed when burning DVD etc I have never had the symtoms you describe, but I know others have.
I have not removed beagle, but as you say it has cured some other peoples faults

To disable just type powernow=off

Hi
I did not think you were being lazy :)

In Bianca KDE, there is kpowersave:
frontend to powersave for setting user specific policies
KPowersave is the KDE frontend for the powersave daemon. It provides
battery monitoring, suspend/standby triggers and many more features
for KDE (and GNOME).

Current feature list:
* support for ACPI and APM
* trigger suspend to disk/ram and standby
* switch cpu frequency policy (between: performance, dynamic and powersave)
* applet icon with information about AC state, battery fill and battery
(warning) states
* applet tooltip with information about battery fill and remaining battery
time/percentage
* autosuspend (to suspend the machine if the user is a defined time inactive)
* a global configurable blacklist with programmes which prevent autosuspend
(e.g. videoplayer and cd burning tools)
* trigger lock screen and select the lock method
* sound for: battery states, AC adapter events and autosuspend
* online help
* localisations for many languages
KPowersave support schemes with following configurable specific
settings for:
* screensaver
* DPMS
* autosuspend
* scheme specific blacklist for autosuspend
* notification settings

Very handy, you can just click on the "frequency" you wish your processor to run at.


Maybe worth giving Biaca KDE a try?

About to install it myself, immediatly added KDE to Bianca when it came out,
(apt-get install kde), now when I try to add Kpowersave, I get told by Synaptic
I must uninstall KDE :)

Good luck
