Спасибо за советы, поставил Cpufreqd, запустил как службу systemctl enable Cpufreqd, помониторил частоту проца, как было так и осталось. Может я что не понял, но этот Cpufreqd у меня не работает)
Может просто сделать вот так?
cpupower frequency-set -g powersave

P.S. Да ноут такой)
P.S. За ссылку про убунту отдельное спасибо)
Здравствуйте уважаемые.
Появился у меня ноутбук DNS m100, поставил arch c gnome 3.
Вопрос: как добиться хорошего энергосбережения?
Судя по этой статьи CPU frequency scaling
Нужно просто поставить Cpufreqd из аура. Настраивать его никак не надо чтоль?
Был установлен и xf86-input-evdev и xf86-input-keyboard. Видимо конфликтовали..
В общем разобрался.
Удалил пакет:
pacman -Rss xf86-input-keyboard
И она заработала, только не понятно, ведь в файле /etc/X11/xorg.conf.d/10-evdev.conf
чётко прописано, что для клавы нужно использовать Driver "evdev"
#
# Catch-all evdev loader for udev-based systems
# We don't simply match on any device since that also adds accelerometers
# and other devices that we don't really want to use. The list below
# matches everything but joysticks.

Section "InputClass"
        Identifier "evdev pointer catchall"
        MatchIsPointer "on"

        MatchIsTablet "on"

Объясните дураку как так вышло?
