    Re: How to get Nvidia geforce 420M working?

    OH!! Thanks a lot mate .. really really helped!!

    What i Did to (supposedly) turn off nvidia :
    $ git clone https://github.com/peberlein/acpi_call
    $ cd acpi_call
    $ make
    $ insmod ./acpi_call.ko
    $ ./m11xr2.sh off


    Thats it ... The battery usage really came down!

    $cat /proc/acpi/battery/BAT0/state
    (from)
    present rate: 1778 mW
    (to)
    present rate: 1236 mW


    I am using a 9 cell ... will update this post on with and without nvidia discharge times

    ^ That is what I did here: http://ubuntuforums.org/showthread.php?t=1703301

    Although you must run it each time you boot. I am using a hack job way to get around that by running a script at login(its on the 2nd page I believe). But if someone can figure out how to load the module into the kernel at boot that would be great. From there we could probably make a simple on/off switch to control the nvidia. Almost giving us manual control of the optimus. Although Idk for sure that linux will make use of the Nvidia at all while it is on.

    The GUI already exists;you have to install GCC...

    Load module at boot:

    Got busy so sorry for the late reply. The first link wasn't usable because it appears to be for Ati cards. The second was loads of help though. Thanks a bunch for that one. =D
    I was able to revise a better way going about disabling the 420m
