CPU scaling

Hello. I've installed Xubuntu 11.04 on my laptop. This computer is not recent: it's a P4-M 1.8 GHz with 1 GB ram and Intel Centrino chipset.
In the past years I've used a lot of distros: from Ubuntu to Suse to Arch and never had problems with CPU scaling.

With XFCE I'm not able to get it working.... I tried xfce-cpufreq-applet but the only thing I get is to know the current clock and governor: I cannot change them.
Is there a setup to do? Or is there another software I can use?

Re: CPU scaling

Xfce4-power-manager can handle this through polkit/consolekit, however setting the governor to ondemand is always your best option.

Re: CPU scaling

I'm also having strange behaviours, I don't know of they are related to Xubuntu or to XFCE.
With no apparent reasons, I see that the CPU clock jumps to 1.8 MHz and CPU fan start "flying"... If I check the status with xfce-cpufreq-applet, I see that the governor is "ondemand" but the clock is "1.8". Cpufreq-info from terminal says that the CPU clock is choosen between... 1.8 and 1.8!
If I check in /sys/decives/system/cpu/cpu0/cpufreq/scaling_min_freq I see 1800000 as le minimum throttle clock.... it's strange...
I have to modify by hand that file.... waiting fot the next clock rising...
