    AMD Phnom II x3 CPU temp in ubuntu

    I have had this CPU for almost 2 months already and works great.

    The only problem is that i cannot get CPU temp in Ubuntu 9.04. I have googled wide and far, but to little avail

    In the bios I can see the temp of the cpus and the alarm there works quite well, so it is more about monitoring than overheating.

    I have tried to follow the instructions here
    but at point 2 I get

    Code:
    sudo: Makefile: command not found
    any idea?

    thanks

    for me working:

    sudo apt-get install lm-sensors
    sudo sensors-detect

    BTW, I am not sure thouse numbers, but show temp diffrenc , anyway.

    I did it already and i get

    Code:
    #----cut here----
    # Chip drivers
    # no driver for AMD K10 thermal sensors yet
    #----cut here----
    The links I gave on top have workarounds and howtos but they don't work for me

    So, I have downloaded the module k10temp. It is a little program.

    Now, I don't know what to do with it. I post its content in case anyone can help me compiling it

    I managed compiling that.

    It is a hassle to compile after every kernel update, but at least it works

    could you elaborate on your solution? I can't get anywhere. I have an amd phenom II x4 925 on ubuntu 9.10.

    thanks.
