  1. Do you think this will work for 10.04 as well? I am trying to build a 3.5.2 kernel, ideally optimized for Ubuntu 10.04 and was initially running into issues with kernel headers on install. This was preventing me from building the nvidia driver from their .run files...

    Also, do you have any estimates as to the performance differences with an optimized kernel?

  2. Were you unable to install kernel headers ?

    If you have kernel headers installed and only problem is while installing nvidia driver, then try xorg ppa as follows

    sudo apt-add-repository ppa:ubuntu-x-swat/x-updates
    sudo apt-get update
    sudo apt-get upgrade

    The last one will upgrade your nvidia drivers to the latest one and enable you to build the dkms modules with latest kernels

    The speed difference is not huge, instead of booting in 10 seconds, my system boots in 6 or 7 seconds, apps open a bit faster and chrome loads even faster, so it is not much of a gain

    I have not done a systematic benchmark, so there is no proof if it is worth the effort

    1. The kernel build enables me to run the latest kernel with ubuntu patches which I think is the real gain
