    how to run i8kutils-37 for dell fan control?

    As many ubuntu users i am struggling with a fan that is always on full speed. Launchpad now suggested a specific solution for dell laptops that needs to be installed called 'i8kutils-37'. I've downloaded the package and read the readme file but I don't understand how to install it. Can someone help me? Package can be found on https://launchpad.net/i8kutils. I think it also needs root access, but how do I get this?

    Tx for helping me out, Cozze

    The easiest way is to install the ppa, and use apt-get.

    sudo add-apt-repository ppa:vitorafsr/ppa
    sudo apt-get update
    sudo apt-get install i8kutils

    After that you will need to tweak the config file "/etc/i8kmon.conf". One example is below.


    # Sample i8kmon configuration file (/etc/i8kmon, ~/.i8kmon).

    # Kernel I8K status file
    set config(proc_i8k) /proc/i8k

    # Kernel APM status file
    set config(proc_apm) /proc/apm

    # Kernel ACPI status file
    set config(proc_acpi) /proc/acpi/ac_adapter/0/status

    # External program to control the fans
    set config(i8kfan) /usr/bin/i8kfan

    # Applet geometry, override with --geometry option
    set config(geometry) {}

    # Run as daemon, override with --daemon option
    set config(daemon) 0

    # Automatic fan control, override with --auto option
    set config(auto) 1

    # Report status on stdout, override with --verbose option
    set config(verbose) 0

    # Status check timeout (seconds), override with --timeout option
    set config(timeout) 5

    # Temperature display unit (C/F), override with --unit option
    set config(unit) C

    # Temperature threshold at which the temperature is displayed in red
    set config(t_high) 80

    # Minimum expected fan speed
    set config(min_speed) 1800

    # Temperature thresholds: {fan_speeds low_ac high_ac low_batt high_batt}
    # These were tested on the I8000. If you have a different Dell laptop model
    # you should check the BIOS temperature monitoring and set the appropriate
    # thresholds here. In doubt start with low values and gradually rise them
    # until the fans are not always on when the cpu is idle.
    set config(0) {{- 0} -1 55 -1 55}
    set config(1) {{- 0} -1 55 -1 55}
    set config(2) {{- 1} 50 65 50 65}
    set config(3) {{- 2} 55 128 55 128}

    # end of file
