Re: after kernel re-compile tons of sound errors

[Craig Hagerman <craighagerman@gmail.com>]

Hi again,

I was not able to figure out all of the sound errors, but I have fixed
everything. I think that (maybe) the problem had to do with compiling
and installing a kernel manually vs. the debian way. I have been
wrestling with a new kernel compile all last night and this morning
and tried to do this with dpkg a couple times. I think maybe there was
some kind of conflict between that and my later manual compile and
install.

I got around the problem by downloading the lastest stable kernel
(2.6.14.5) and doing a manual compile and install. This meant that the
/lib/modules/2.6.14.5 directory was brand new (since I think the
problem was in the old /lib/modules/2.6.14 directory)

I also discovered that you have to recompile and reinstall the nvidia
module after installing a new kernel.

Here is how I installed the 2.6 kernel and nVidia module:

--------------------------------------
	Kernel
--------------------------------------

download lastest stable kernel from www.kernel.org
(linux-2.6.14.5.tar.bz2) into /usr/src
extract

% tar xvfj linux-2.6.14.5.tar.bz2

link linux-2.6.14.5 to linux:

% ln -s linux-2.6.14.5 linux

move to that directory

% cd linux

I already spent a lot of time selecting options for the kernel so I
simply copied the .config file from the previous kernel

% cp ../linux-2.6.14/.config ./

check the kernel config and alter as needed:

% make menuconfig

Make new kernel image

% make clean
% make bzImage

Make & install new modules:

% make modules
% make modules_install

Copy kernel image to /boot

% cp /usr/src/linux/arch/x86_64/boot/bzImage /boot/


--------------------------------------
	Lilo
--------------------------------------

update lilo, add information about new image, run /sbin/lilo

% vi /etc/lilo.conf

	image=/boot/bzImage
        		root=/dev/hda6
        		label="Linux-2.6.14-5"
       	 	read-only

% lilo


--------------------------------------
	nVidia Modules
--------------------------------------

Download and install nVidia module source, which creates a source
tarball in /usr/src

% apt-get install nvidia-kernel-source nvidia-kernel-common

extract tarball

% tar -xfvz nvidia-kernel-source.tar.gz

Build the kernel module and nvidia module the 'debian way' (even
though I won't use the kernel_image)

% make-kpkg clean
% make-kpkg kernel_image modules_image

This creates a kernel-image.deb and nvidia-kernel.deb in /usr/src. The
debian way is to then use "dpkg -i" to install both. Instead I
installed only the nvidia module

% dpkg -i nvidia-kernel-2.6.14.5_1.0.8178-1+2.6.14.5-10.00.Custom_amd64.deb

Make sure that nvidia-glx is installed

% apt-get install nvidia-glx


--------------------------------------
	xorg.conf
--------------------------------------

Edit /etc/X11/xorg.conf
Make sure that the Module section contains:
Load 		glx
And comment out:
#	Load		dri
#	Load		GLCore

To enable TV out edit the xorg.conf "Device" section something like this:

Section "Device"
        Identifier      "Generic Video Card"
        Driver          "nvidia"
        Option          "TwinView"
        Option          "TwinViewOrientation"   "Clone"
        Option          "SecondMonitorHorizSync"        "30-50"
        Option          "SecondMonitorVertRefresh"      "60"
        Option          "MetaModes"     "1024x768, 1024x768; 800x600,
800x600; 640x480, 640x480;"
        Option          "TVStandard"    "NTSC-J"
        Option          "TVOutFormat"   "SVIDEO"
