Intel Atom/NVidia ION

Intel Atom and NVIdia ION based motherboards are a cheap and powerful combination for a DIY thin client. In this case we need to get it working with the correct resolution (LCD 1680x1050). Here are two cases. In the first case all thin clients are NVidia ION based. The second case is for when there is only one NVidia ION based thin client (others can be Intel, ATI or VIA based).

Case 1 - All thin clients are NVidia ION based

First unlock root access and upgrade chroot. Here are howtos for that. https://help.ubuntu.com/community/UbuntuLTSP/UnlockChrootRootAcct https://help.ubuntu.com/community/UbuntuLTSP/UpdatingChroot After that we have latest kernel in chroot.

ssh [email protected] 

uname -a
Linux ltsp201 2.6.28-15-generic #49-Ubuntu SMP Tue Aug 18 18:40:08 UTC 2009 i686 GNU/Linux

Install NVidia in chroot

Install the latest 'nvidia-glx-xxx' package for your Ubuntu version in chroot.

sudo su

export LTSP_HANDLE_DAEMONS=false

chroot /opt/ltsp/i386

mount -t proc proc /proc

Check for NVidia.

Exit from chroot.

umount /proc

exit

Rebuild image.

ltsp-update-kernels

ltsp-update-image

Add xorg.conf for NVidia Ion

We have produced the correct xorg.conf file for NVidia Ion in the chroot. Now we can use it.

sudo su

cd /opt/ltsp/i386/etc/X11/

wget http://www.arkki.info/howto/Wiki/LTSP5/ion-xorg.conf

mv ion-xorg.conf xorg.conf

Update lts.conf file for new xorg.conf file. - This is not necessary for Ubuntu 9.10 and 10.04!!

cat /var/lib/tftpboot/ltsp/i386/lts.conf

[Default]
CONFIGURE_X = True
X_CONF = /etc/X11/xorg.conf

Update image.

ltsp-update-image

We have now the correct NVidia driver for our kernel and the right xorg.conf.

Case 2 - one thin client is NVidia ION based

Remove chroot.

sudo su

rm -rf /opt/ltsp

Make a chroot for all the thin clients

First make a chroot for all the non-ION based thin clients.

ltsp-build-client --base /opt/ltsp --chroot i386

Upgrade that chroot.

sudo cp /etc/apt/sources.list /opt/ltsp/i386/etc/apt/sources.list

export LTSP_HANDLE_DAEMONS=false

chroot /opt/ltsp/i386

mount -t proc proc /proc

apt-get update && apt-get dist-upgrade

umount /proc

exit

sudo ltsp-update-kernels

sudo ltsp-update-image -a i386

Make chroot for NVidia ION based thin client

First make a chroot for Nvidia ION based thin client.

ltsp-build-client --base /opt/ltsp --chroot i386-ion

Upgrade that chroot.

sudo cp /etc/apt/sources.list /opt/ltsp/i386-ion/etc/apt/sources.list

export LTSP_HANDLE_DAEMONS=false

chroot /opt/ltsp/i386-ion

mount -t proc proc /proc

apt-get update && apt-get dist-upgrade

umount /proc

exit

sudo ltsp-update-kernels

sudo ltsp-update-image -a i386-ion

Install the current 'nvidia-glx-xxx' for your Ubuntu version into that chroot.

chroot /opt/ltsp/i386-ion

mount -t proc proc /proc

apt-get install nvidia-glx-180 (Ubuntu 9.04)

ltsp-update-image -a i386-ion

Setup for two chroots

We have two chroots and two directories for tftpd. The image for i386-ion is bigger because it includes drivers for NVidia.

Here is i386's default file for pxe. This way you are able to see boot processes (no splash). The port is default port (=2000)

admin-ltsp5@ubuntu-ltsp5:~$ cat /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default
DEFAULT vmlinuz ro initrd=initrd.img

Here is i396-ion's default file for pxe. This way you are able to see boot processes (no splash). The port is different from the regular i386 port.

admin-ltsp5@ubuntu-ltsp5:~$ cat /var/lib/tftpboot/ltsp/i386-ion/pxelinux.cfg/default
DEFAULT vmlinuz ro initrd=initrd.img nbdport=2001

We have in this case only one NVidia ION based thin client. We have a fixed ip number for that, all other thin clients have dynamic ip numbers. Here is an example dhcpd.conf file.

authoritative;
subnet 192.168.1.0 netmask 255.255.255.0 {

        # COMMON

        option domain-name "ubuntu-ltsp5";
        option domain-name-servers 192.168.1.1;
        option broadcast-address 192.168.1.255;
        option routers 192.168.1.1;
        option subnet-mask 255.255.255.0;
        option log-servers 192.168.1.1;

        # ION ONLY

        group   {
                use-host-decl-names       on;
 
                host ltsp200 {
                hardware ethernet     00:26:18:6E:B4:E0;
                fixed-address         192.168.1.200;
 
                if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {
                filename "/ltsp/i386-ion/pxelinux.0";
                         }
                         else{
                         filename "/ltsp/i386/nbi.img";
                         }
                         option root-path "/opt/ltsp-ion/i386";
                }
 
        }

        # ALL OTHERS

        range 192.168.1.201 192.168.1.254;
        if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {
        filename "/ltsp/i386/pxelinux.0";
        }
        else{
        filename "/ltsp/i386/nbi.img";
        }
        option root-path "/opt/ltsp/i386";
 }

We also need the right xorg.conf file, just like in first case.

sudo su

cd /opt/ltsp/i386-ion/etc/X11/

wget http://www.arkki.info/howto/Wiki/LTSP5/ion-xorg.conf

mv ion-xorg.conf xorg.conf

Update the lts.conf file for new xorg.conf file.- This is not necessary for Ubuntu 9.10 and 10.04!!

cat /var/lib/tftpboot/ltsp/i386-ion/lts.conf

[Default]
CONFIGURE_X = True
X_CONF = /etc/X11/xorg.conf

Update the image.

ltsp-update-image -a i386-ion

After these steps the NVidia ION based thin client will play nicely with all others thin clients. Here are some lines from daemon.log.
