I did cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor etc. several times, but nothing seems to happen...
Only when I set scaling_governor to "userspace" by hand and then start cpufreqd it changes the governor to performance.

| What? The Governor? This isn't possible, the only values /sys/device/system/cpu/cpu0/cpufreq/scaling_governor accepts is performance, powersave and userspace... |

Did you emerge acpid ?
If you did not that's why it does not work.
Well did you plug and unplug your AC adapter ? Did you see any difference in the governor set by cpufreq ?
Anyway, is the cpufreqd running as a deamon ?
You need to reboot before attempting to see if it works.
To see the real frequence of you processor, you can do a
| Code: | emerge x86info
x86info -mhz |
And if you enable /proc/cpu/msr and /proc/cpu/cpuid in the kernel options, you can see it with | Code: | | cat /proc/cpuinfo | grep Mhz |
Personally I use speedfreq with ondemand policy. It changes the frequence very quickly and I never had any problem. I use a centrino laptop. |

I solved the problem meanwhile. The problem was the order of the rules in cpufreqd.conf, so it always took the first rule...

You need to enable "'ondemand' cpufreq policy governor" in the kernel.
