[gentoo-user] is there a good independent power-manager?

[Benjamin Block]

Hi,

after the recent stabilization of gnome3 I want to migrate away from the
whole gnome-toolchain. Maybe I will migrate to systemd in some months, if
everything has settled down but as for now I don't think I gain anything
from it.

The thing is, on my laptop I used to use the gnome-power-manager along
with cpufreqd and laptop-mode to manage battery-mode. Is there any good
replacement for this tool that doesn't belong to one of the big
desktop-environments (I use i3 since 2 years ago)?

best regards,
