    Ahh! Thanks for the help, Varun. It's great to have the additional information.

    Myself, I don't know which end of the video card to hit with the hammer!

    Usually the center of the card is a good spot, but the hammer should be at least 2.5 Kg or more, from a height of no less than 1 meter, full force..

    To Varun


    Code:
    So, is your system the one that offers an Intel+Nvidia Hybrid crossfire  graphics? If so, I have read that it is problematic in Linux.
    
    In any case, your native Nvidia driver 'nouveau', the proprietary one  proposed by default 'nvidia-current' are blacklisted, so can't load, and  the one which has blacklisted them doesn't seem to be loaded either  (bumblebee - I'm not sure if that is the name of the driver as well). As  such, I believe you have not achieved what you wanted to achieve by  installing bumblebee, and so you should sort out you graphics issues  first. I don't know what that fix maybe - perhaps disable hybrid  graphics and prefer only the Intel one in BIOS, or remove the blacklist  file so that the native one may load (may be more problematic in case of  hybrid graphics.
    Yes I have an Intel+Nvidia Hybrid crossfire graphics.
    two days ago I started using the nvidia graphisc card (with dirver bumblebee) to load firefox. everything works fine and there are no freeze.
    I'll try a few more days, if everything is ok I will make a transition to kernel 3.5, 3.8 or 3.11.
    I'll let you know how it works .........

    I'll wait with curiosity to see your report/feedback, hopefully the final one.

    In the meanwhile, can you also post the output of "lsmod" again please? Just curious to see if there is a difference now.

    Yup, the "difference" is on the top!

    Hope it remains stable, which would remove another doubt I have about that "mxm_wmi" driver.

    Thank you for taking time to provide us your feedback, it's very much appreciated.

    as you can see is different from the previous one (kernel 3.2).

    Now I will test the connection wi.fi ........

    I'll give you information

    Are you hooked to the internet so the package can be found and downloaded? Have you built an index of available packages?
