    +1 to realzippy.

    If you cant disable the nVidia GPU in the BIOS (or possibly 'force' the intergrated video only) the nvidia GPU is on, but basicly useless. It will just suck power.

    As for how to turn if off if there is no BIOS switch, I have no idea.

    Idea.

    But you need to write that into a script to boot, if not you're gonna have to do all that manually on each boot.
    I support SOPA and I dare say it.

    That might work on Intel/ATI combos,with optimus it not seems to work. Edit. work always.

    If you do not have a folder
    /sys/kernel/debug/switcheroo (only Intel/Ati combos seems to have..)
    this does not work..
    Wrong. My previous Gateway ID59c-04h which had Optimus can have it turned off. All you need to do is:
    Code:
    git clone http://github.com/mkottman/acpi_call.git
    
    cd acpi_call
    
    make
    
    sudo insmod acpi_call.ko
    
    ./test_off.sh
    SUCCESS IS NOT GUARANTEED. It worked for me (power consumption dropped immediately from 17W to 10W after executing).
    I support SOPA and I dare say it.

    Re: nVidia Optimus and Ubuntu explained

    ..remember if you had /sys/kernel/debug/switcheroo ??


    tried the test.sh script 3 weeks ago,it did not work.
    If you have a minute,please have a look here.
    Do you have an idea what to do?
    Really would like to power M310 off...

    Interesting, that I do not know. Check the battery Rate again.

    Re: nVidia Optimus and Ubuntu explained

    Hey, I've got an Asus N53j which runs with
    Code:
    00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 18)
    01:00.0 VGA compatible controller: nVidia Corporation GT215 [GeForce GT 335M] (rev a2)
    First thank's for the info on how to turn off the nvidia chip (with a rather poor bios, no options regarding video at all), not sure it works though, I'll try checking the power consumption after a reboot.

    I'm however having trouble enabling effects on compiz with the Intel integrated graphics, I'm currently running without a xorg.conf

    Any ideas ?

    (PS johan_olsen's Edit note with Cairo and Emerald did not work for me)

    Output of compiz command :
    Code:
    Xlib:  extension "GLX" missing on display ":0.0".
    compiz (core) - Fatal: glXCreateContext failed
    compiz (core) - Error: Failed to manage screen: 0
    compiz (core) - Fatal: No manageable screens found on display :0.0
    
    Launching fallback window manager

    Bumping it up.

    Also the acpi calls works great, with 2 weird bugs (so far), when the nvidia card is off, weirdly enough if I try to run Skype the computer freezes, hardcore way, can't move mouse and not responding to any keyboard signal, ctrl alt f1 included. Also on shutdown if the nvidia card is off, it freezes too at different stages (really weird too).

    For skype I run it before opening a shell that runs the script, after that everything works great whether the nvidia card is on or off, and I wrote a quick script similar to test_off.sh, replacing the end of the command that "works" with ON instead of OFF to turn it back on, and placed it in /etc/rc6.d so it's triggered on shutdown.

    Saving more than 1hr battery with the trick !

    Still can't run compiz w/ effects though ^^

    Re: nVidia Optimus and Ubuntu explained

    I can tell the suggestion of 3602 worked for switching from Activated NVIDIADiscrete GPU to Intel Integrated GPU. Now the fan doesn't spin that hard and probably the battery will last longer.

    Still no success in getting more functionality out of the integrated card.

    A led still informs me that Optimus Mode Activated, but not UMA Mode Activated. "In the UMA Mode system will use only integrated GPU (part of Intel's Arrandale technology) for maximum power-saving. - In the Optimus Mode will allow the system to automatically determine whether to use discrete GPU (dGPU) and integrated GPU (iGPU) depending on task and/or application"

    So I'm not sure what I've achieved, but the dGPU seems to be deactivated.

    If somebody has any idea how to increase screen resolution post it here!

    This post is definetely gathering all the information about the issue.

    Somebody has a clue if the issue will be solved one day or another by either nvidia or xorg or nouveau guys?

    Thanks to everyone for the work achieved so far!

    Re: nVidia Optimus and Ubuntu explained

    I would like to have two kernels in Grub, one for nvidia and other to Intel.

    Is there a way that we could do that? Can you tell me? I think most of the users with optimus would appreciate that!!

    Best Regards
