    Re: HowTo: Undervolt your notebook CPU for longer battery life

    Hello everyone,

    I was just wondering - any chance of getting this working on 12.10?

    Any success stories?

    Reviving an old thread here. Apparently PHC is no longer available (or not supported on 3.0+ Kernels).

    Please see below and if you can help me, I would really appreciate it. For those who read this and cannot assist me, thank you as well for your time. =)

    $ sudo apt-get install linux-generic-phc linux-headers-generic-phc

    Same / similar error appeared before and I did update -f, which I thought fixed it. It did not.

    Sorry I cannot help you. I switched to CentOS due to the recent decisions from the ubuntu leadership.

    Best wishes
