laptop cpufreq events

CPUSpeedy is really good-looking. I think I will pop it in, when I have recompiled my kernel.

it has a gtkbased graphical user interface and does the job perfect
http://cpuspeedy.sourceforge.net/

the info says it uses the sysfs interface for 2.6.x / 2.5.x kernels and its made for "...save battery consumption and reduce the temperature of your laptop.". That would fit properly in my machine ... downloading already

... shall try it tonight, I appreciate the tip.

BTW by some googling I had found this monitoring also gtk-based application called GKrellM, it's nice, quite versatile and finely configurable.

As you yourself suggest, Gkrellm monitors the system. It does not actually influence the settings.

yeah I knew, I just wanted to tell about it. Along with cpufreq stuff I was looking for some temperature monitoring solutions. This was the chosen one.

Thanks again anyway.

Peace.

HI all,

I am having problem with do a manual freq set or using CPUSpeedy to do so for me.
I receive error: cpuspeedy: error: ERROR_NO_INTERFACE
Am using Slackware10.1 with kernel 2.6.15
I have SYSFS mounted as /SYS and ACPI/APM enabled.
I am using 'userspace' as the default governor and but also have the 'performance' governor selected.
I chose the 'ondemand' poliy governor for use with the 'userspace;

I chose the Intel Enhanced Speedstep CPUFreq driver with i also included ACPI tables to use for freq/voltage changes.

When i boot the machine with AC it clocks at a lovely 1798mhz
when on battery it runs at 598mhz - which is the same in windows...

I was hoping to be able to either manually set the freq to say 800-900mhz or when using the 'ondemand' governor it would set the freq on the fly (maybe between 600 and 1800 mhz? ) ??

When i try a command like cpuspeedy -s (for status) it says Error No Internface

If i try cat /proc/cpuinfo it reports CPU0 i running at xx clock speed??
i have a feeling that this has something to do with the fact that when i go into: /sys/devices/system/cpu/cpu0 - there is nothing in there?

what have i done wrong?
In KDE i can do manual CPU throttles (which work) - No point when my machine is already running at a mere 600Mhz
