    I have compiled kernel 3.1 64 bit for ubuntu oneiric with configuration for CORE2 march=native and mtune=native. I have two versions, one is compiled with ubuntu patches and second one without ubuntu patches.

    (I have maximus iv extreme R3 BIOS 1850 motherboard. HD6990 with catalyst 11.8 properly working).

    I have problem to switch to console by Ctlr+Alt+FN1.

    It is always switched properly into console but has displayed blank screen.
    (I can type login name and password and it evidently made login)
    but I do not see anything displayed.

    The problem is not catalyst graphic driver because when I ran under xorg-edgers compiled kernel 3.1 or another kernel from ubuntu ppa - it works just fine - console behaves normally.

    Could anybody please help to kernel newbie to let me what am I missing within kernel compilation?

    thanks a lot for any clue,

    Did you use the configuration of the working kernel when you compiled the new one, or did you configure it from scratch?

    from scratch.

    I think you should use the configuration of the working kernel as a start point.

    1. I would like to know what I should switch on/off when menuconfig starts - to make console displayable ?
    2. I have read that each new kernel version has slightly different config. How to manage it - by diff to see what is new , removed , depracated, my changes ?
    3. which configuration file should I try to compile kernel for 64 bit oneiric ?
    4. I have read that redhat 6 enterprise configuration is good but I am using ubuntu oneiric. Woul it be a problem ? I did not try to compile kernel yet.
    5. I would like to make some settings by myself:
    ( at this moment I am using
    tried as well:
    ---I have i7 2600k -- which setting may I use for this processor ?
    I would like to try to have support avx instruction set.
    found this:
    or anything else may I try ?
    Kernel Timer Frequency set to 1000 HZ
    Transparent hugepage support enabled
    is there anything else I can use within kernel compilation what coul be useful for i7 2600k processor and maximus iv extreme motherboard ?

    6. is there any documentation on-line or book describing some examples what config settings is useful , many-times-used , usually-used for ? I am not saying all of it, but just some with explanation what is it for ?

    I would like to learn more about kernel compilation to better understand.

    thanks for any help, urls, descriptive examples , book/s links.

    My idea is:
    At this moment my script has 2 options:
    1. normal kernel compilation from source code - works.
    2. kernel compilation with ubuntu patches - works.
    3. option is not done yet. and it should be compile kernel with 3rd party configuration file (like redhat el 6 ).

    Within all these options I have to manually change (like is described in URL you pointed to) configuration.
    I would like to amend my script to NOT to use manual intervention. Is it possible to generate default configuration file automatically ? And why I need this ? Because I am going to have all the time the last default config changes.

    - Let's say I have some settings for i7 2600 sandy bridge.
    - compare it with generated configuration file with default settings - I would like to know how to do it without manual intervention ?
    - apply my changes to default config file.
    - compile kernel with this new config.

    if this is wrong - so I am looking for some another attitude satisfied not to manually make config changes :)
