kernel 3.1 switch to console display nothing

[masuch]

Hi,

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,
regards,
Martin

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
core2
march=native
mtune=native
tried as well:
mtune=corei7
mtune=corei7
---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:
march=corei7-avx
mtune=corei7-avx
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.

Take a look at chapter 5 on http://www.howtoforge.com/kernel_compilation_ubuntu_p2 to learn how to use the configuration of a working kernel for a new kernel.

thanks,

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.

Example:
- 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 :-)
