    It sounds perfect to me. The machine should stays quite and cool when you are not using the Geforce card (thanks to bumblebee that turns it off), but only until you put it to work using "optirun application". Why do you think is not working?

    I've got the same results. I don't know why the performance went down so bad. The driver is the same. About the battery, I'm not using windows at all, but ephestione reported 20 W in win7 (#20), so the battery should last the same as I'm getting similar values. These are my results (in Watts):
    Code:
                    NvidiaOff   NvidiaOn   glxsph.   ScreenOff
    Ubuntu_11.10     16.24        22.12     52.82     -
    Ubuntu_12.04     17.17        23.87     51.96    11.77
    In all cases the machine was idle, but in "glxsph." in which case I had glxspheres running. For more details, see the attached file (funny that I had to add the ".txt" extension to be able to upload it in an linux forum...).

    Updated the guide with a fix for the subwoofer (to read more, check this, specially comment #34).

    came to check in here before hitting the 12.04 upgrade... seems everything's fine, maybe better, with precise.
    I'll be upgrading for the rest of the morning

    Then set a key combination for that command (e.g. Shift + F9, tried Fn + F9 but it doesn't work). That's all, works perfect.
    Hi,

    I'm not running Ubuntu and I have the N55SL (but I believe it's pretty much the same as the N55SF) so sorry if this is noise, but:

    Fn + F9 on my laptop sends a XF86TouchpadToggle KeyPress event (I checked with xev) which sounds pretty standard to me, and, indeed, after installing the ktouchpadenabler module in KDE, Fn + F9 works to disable my touchpad. (This is with kernel 3.3.5 and Xorg 1.12.1) If you're not using KDE, this thread sounds promising: http://forums.opensuse.org/english/g...os-12-1-a.html

    Since I may as well ask: Do any of you sometimes experience the fan starting up (very lightly; I once had it do so just by running nano!) and then stopping after one second? This occurs consecutively for me and I do find it slighly odd. cpufreq is enabled (I'm using Granola) and i7z says that the CPU is running at 800MHz (same as in Windows according to Core Temp when I'm not doing anything heavy). The NVIDIA card is disabled; I checked, thanks to gu79's awesome guide.

    I was also having this problem when the computer suspended. I have stopped the behaviour by disabling "Monitor power management control" in my XFCE power management options. Not ideal but better than having to force a reboot.

    I found this solution for HDMI output:

    http://www.webupd8.org/2012/08/get-h...ptimus-on.html

    It works on my N55SF. Good for watching movies and office work, but not usable for playing games. Keyboard responce is slow.
