It's awfull to play on debian etch..
I spent almost two weeks to solve debian system problems and upgrade the kernel from 2.6.8 to 2.6.18.
It's first time for me to play linux as a root, also first time for me to touch the heart of computer-kernel...
The first problem is no higher resolution for my new LCD.
The second problem is no mouse been found.
The third problem is ungrade failed.
I write the problem and solution here for me and other guys who have same problem.
1,for higher resolution.
All x-server information was setted in /etc/X11/xorg.conf. Before you want to change it ,you should save it in a copy file,like xorg.conf_old.
First you should know your graphic card information, of couse ,sometimes you don't know ,becouse you are not the guy who build it. If you want to know it ,the best way should be to look /var/log/Xorg.log.0. There you can see many information about the xserver.
From log file ,I see my graphic card is nVidia, which need nv driver. And I see the best resolution 1280*1024..You also can see why some mode of resolution can not be used by xserver..(such as frequence much more than maxmimum 144MHz). For Lcd, YOu don 't need big frequence, 60Hz is ok. If there is no right mode , you can add modeline in xorg.conf by yourself.
DisplaySize 380 300
Modeline "1280x1024" 108.88 1280 1360 1496 1712 1024 1025 1028 10
Modeline "1280x1024" 106.97 1280 1360 1496 1712 1024 1025 1028 10
Modeline "1280x1024" 105.15 1280 1360 1496 1712 1024 1025 1028 10
In fact , my problem is that I choose wrong driver "vesa" for gcard.
I do :(# as root)
#dpkg-reconfigure -phigh xserver-xorg
It show me to choose driver,so I choose "nv". Now restart x server by type "startx" in shell or CTL+ALT+BACKSPACE.
This time I can not use mouse anymore.
I use old input setting for the mouse and restartx. This time it works. I can see the higher resolution in Desktop->preference->screen resolution. Then I choose higher resolution. I get it.
2, no sound .
Old kernel version is 2.6.8, but my debian is etch which should be has 2.6.18 or newer version .
In linux ,alsa is a tool to manage the sound setting.
For 2.6.8, alsa is a part of kernel. But in etch ,it need more modules .
I install alsa-base and alsa-util by "apt-get install alsa-base alsa-util".
Now it works.
3,update you kernel in etch.
Fisrt you should update package database and install all needed package:
#apt-get install kernel-package libncurses5-dev fakeroot wget bzip2 build-essential
(1)download the kernel souce, two way :
one way is from debian kernel, you can do:
#apt-get install linux-souce-2.6.18
If you want to know the new version of linux-souce, you can do "#apt-get search linux-souce".
Another way is to download from kernel.org:
I use second method.
(2), After download , unpack the souce code:
#tar -xjf linux-2.6.18.tar.bz2
#ln -s /usr/src/linux.2.6.18 linux
#make clean && make mrproper
Then copy old configure file to here if you want to use old configure file, otherwise skip this. 'uname -r 'is your old kernel version,for me it's 2.6.8-386
#cp /boot/.config-'uname -r' ./.config
This command will show a menu, you need choose "Load an alternate configuration file" and it will show you ./config, choose it and type "yes","exit".If it ask you if save the configure file ,you choose "yes".
#fakeroot make-kpkg --append-to-version=-custom kernel_image kernel_headers
wait about one or two hours.
After it finish, if there is no errors:
Now install these deb file, as it's deb file ,so somebody call it's in debian way.
#dpkg -i linux-image-2.6.18-custom_2.6.18-custom-10.00.Custom_i386.deb
#dpkg -i linux-headers-2.6.18-custom_2.6.18-custom-10.00.Custom_i386.deb
After that, do:
#apt-get install module-init-tools initrd-tools procps
#mkinitrd -o /boot/initrd.img-2.6.18-custom 2.6.18-custom
Add "initrd /boot/initrd.img-2.6.18-custom" in the file like this:
## ## End Default Options ##
title Debian GNU/Linux, kernel 2.6.18-custom
kernel /boot/vmlinuz-2.6.18-custom root=/dev/sda1 ro
title Debian GNU/Linux, kernel 2.6.18-custom (recovery mode)
kernel /boot/vmlinuz-2.6.18-custom root=/dev/sda1 ro single
title Debian GNU/Linux, kernel 2.6.8-2-386
kernel /boot/vmlinuz-2.6.8-2-386 root=/dev/sda1 ro
title Debian GNU/Linux, kernel 2.6.8-2-386 (recovery mode)
kernel /boot/vmlinuz-2.6.8-2-386 root=/dev/sda1 ro single
Now congratulation ,we finish upgrade.
#shutdown -r now
You will see new kernel and old kernel when you start the computer. You can choose anyone whatever.
When I update the kernel to 2.6.24, it tell me that it can not find sda1.
I go to /lib/modules/2.6.24-custom, there I didn't see ata_piix sata_via libata sd_mod scsi_mod etc modules which were needed by SATA.
I get answers from google, that because the configure file is different between 2.6.8 and 2.6.24.
For 2.6.8, in configure file it like:
But in 2.6.24,it likes:
# CONFIG_ATA_NONSTANDARD is not set
So if you use old configure file for 2.6.8 to configure 2.6.24, you should notice this difference.
Before you copy ,first you should change the name from CONFIG_SCSI_SATA to CONFIG_SATA.("m" is modules loaded by kernel, "y" is built in the kernel)
