Hello! Here is a set of commands that I used to install my karmic!
First, I have downloaded and installed Karmic 64bits (amd64 means 64bits for all CPU, not only for the AMD ones)
I installed it in French so I needed to install the language support from the GUI popup after the first boot.
After that, I did a full update of the system:
sudo apt-get upgrade -f
Then I install a lot of stuff that is needed to make ubuntu work by default like I want it to work 
. Install Medibuntu, install DVD support, install restricted codecs and all the ubuntu restricted extras. Also install smbfs, openssh-server and electricsheep (my favorite bandwidth consuming screensaver):
sudo wget http://www.medibuntu.org/sources.list.d/`lsb_release -cs`.list --output-document=/etc/apt/sources.list.d/medibuntu.list
sudo apt-get -q update
sudo apt-get --yes -q --allow-unauthenticated install medibuntu-keyring
sudo apt-get -q update
sudo apt-get install w64codecs libdvdcss2
sudo apt-get install smbfs openssh-server electricsheep pidgin
After that since I use pidgin, I remove empathy because I did not found how to make Empathy work like I would with the IRC channel…
sudo apt-get remove empathy
Sophie, my tender love, uses Picasa to manage our pictures:
wget http://dl.google.com/linux/deb/pool/non-free/p/picasa/picasa_3.0-current_amd64.deb
sudo dpkg -i picasa_3.0-current_amd64.deb
Then I have updated my hosts file and fstab in order to auto mount a share on my home server:
# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
#
#
proc /proc proc defaults 0 0
# / was on /dev/sda1 during installation
UUID=8001e8ea-19e4-4ff0-b431-87b4e4347779 / ext4 errors=remount-ro 0 1
# swap was on /dev/sda5 during installation
UUID=e9ee2a57-4767-4e72-add0-564bae42f270 none swap sw 0 0
/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0
//serveur/public /media/commun cifs credentials=/root/.smbcredentials,nounix,iocharset=utf8,gid=1001,uid=1001,file_mode=0777,dir_mode=0777 0 0
# /etc/hosts
127.0.0.1 localhost
127.0.1.1 laptop
10.31.31.31 serveur
10.31.31.32 portable
10.31.31.33 salon
10.31.31.34 cuisine
# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
#And then...
sudo mkdir /media/commun
sudo mount -a
After that I create Sophie’s user profile with the ubuntu GUI tool and then restore his profile that I have backuped on the server:
sudo tar -xvzf /media/commun/backup/sophiebk.tgz /home
Since I want my SSH server to be responsive when there is no one loggued on the system, I need to force my wlan0 to be up at boot. To do that, I unfortunately need to remove the default network manager and hard code my router SSID in the conf file. I need to do that because the network manager connect the wlan0 only after a logon. So if I trigger a reboot from ssh, I cannot reconnect until my girlfriend logs on the laptop 
It is sad because when I will take my laptop out, I will need to hack again to be able to connect to « other » network. If anyone has a solution to this problem, your help would be greatly appreciated:
#Good bye network manager! :s
sudo aptitude remove network-manager network-manager-gnome
From http://doc.ubuntu-fr.org/wpa#methode_complete_et_propre
#/etc/network/interfaces
auto lo
iface lo inet loopback
auto wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant.conf
#/etc/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
ap_scan=1
network={
ssid="vinceprangplung"
proto=WPA RSN
key_mgmt=WPA-PSK
group=CCMP TKIP
psk="hahahahahahahahahahahaaaasolutéha!:P"
}
Then I needed to hack the GDM login screen because it shutdown automatically when the laptop screen is down.. In my option, the new GDM is not enough mature to be release and this disappoints me a lot from Ubuntu… I feel like they try to use me like a beta tester before the release of the 10.04 LTS… Same thing the grub2 by the way… Anyway:
From doc.ubuntu-fr.org
From the login screen (with no user loggued), CTRL-ALT-F1 and log as default user
then: export DISPLAY=:0.0
then: sudo -u gdm gnome-control-center
then: ALT-F7 and edit energy settings...
Finally, I little clean up before backuping…
sudo apt-get upgrade -f
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get clean
Now I have a beautiful working installation Since I plan to install weird stuff by compilation, I needed to take a backup of it… Some people suggests that we could do a backup live with tar but I prefer to do this with my hdd unmounted… First, I downloaded and boot the Gparted Live CD to resize my sda1 ext4 partition and create a sda3 backup partition. Then I tar with bz2 my sda1 to sda3:
tar cvzf /mnt/sda3/backup.tgz --exclude=/mnt /mnt/sda1 > /mnt/sda3/tar.log
