cpufreqd и Pentium D
День добрый.
Подскажите как быть с сабжем. Никак не хочет сохранять электроэнергию.
Использую cpufreqd, пробовал так же powernoed и cpudyn но результата
нет.

cat /etc/default/cpufreqd
CPUFREQ_CPU_MODULE="p4-clockmod"
CPUFREQ_GOV_MODULES="auto"
Включил все модули:
sudo modprobe cpufreq_conservative
sudo modprobe cpufreq_ondemand
sudo modprobe cpufreq_powersave
sudo modprobe cpufreq_stats
sudo modprobe cpufreq_userspace
Использую драйвер p4_clockmod. Другие пробовал (acpi-cpufreqd,
speedstep-centrino ), вообще никаких результатов, а с этим cpufreq-info
хоть что-то выдает
sudo modprobe p4_clockmod
cpufreq-info

Report errors and bugs to cpufreq@vger.kernel.org, please.
analyzing CPU 0:
driver: p4-clockmod
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 10.00 ms.
hardware limits: 350 MHz - 2.80 GHz
available frequency steps: 350 MHz, 700 MHz, 1.05 GHz, 1.40 GHz, 1.75
GHz, 2.10 GHz, 2.45 GHz, 2.80 GHz
available cpufreq governors: conservative, ondemand, userspace,
powersave, performance
current policy: frequency should be within 350 MHz and 2.80 GHz.
The governor "performance" may decide which speed to
use
within this range.
current CPU frequency is 2.80 GHz (asserted by call to hardware).
analyzing CPU 1:
driver: p4-clockmod
CPUs which run at the same hardware frequency: 1
CPUs which need to have their frequency coordinated by software: 1

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
conservative ondemand userspace powersave performance
cat /etc/sysfs.conf (в каком то гайде советовали вручную прописать)
devices/system/cpu/cpu0/cpufreq/scaling_min_freq = 350000
devices/system/cpu/cpu0/cpufreq/scaling_max_freq = 2800000
devices/system/cpu/cpu0/cpufreq/scaling_governor = ondemand
На все попытки сменить режим ничего не делает (остается режим
performance) =(
echo conservative >
/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
sudo cpufreq-selector -g ondemand
В общем везде все показывает что норм а переключать не хочет никак.
