--- Comment #8 from Stepan Bakshaev <step2back+freedesktop@gmail.com> ---
I installed kernel from here
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12-trusty/

and try to change power_method by
http://xorg.freedesktop.org/wiki/RadeonFeature/#kmspowermanagementoptions

There are no errors and no success in changing power_method. Where did I do
mistake?
