Finally edited the information on Launchpad homepage.
1. Basically points to Raphael's script.
a. I give recognition to Raphael and Norbert by FIRST NAME. If this
is not acceptable by either or both of you, don't hesitiate
to let me know (for all I know, you're both admins on Launchpad
anyway).
b. Any other sites/info worth mentioning right now?
2. Mentions where to find the legacy info we previously listed (made a wiki
at wiki.ubuntu.com/sonyvaioz).
a. It would be great if People could get in there and clean that info
up for us!
Hope this works for everyone!
I wanted to send Albert a .txt with all the old info (as he is the one that
started this thing) just in case the wiki gets info removed, etc.
I attached it to this email for all of us. Tuck it away somewhere just in
case you ever need it :)

A complete installation howto here by eva-brucherseifer:

You can check the model and generation of you laptop with this command:
sudo dmidecode -s system-product-name
The current battery life with latest sony-laptop module is 5 hours and 30
minutes, with power consumptions as low as 9.5W. To achieve this, use a
standard Jaunty with the following points:
- laptop-mode enabled (package 'laptop-mode-tools'): intel-sata-powermgmt,
sched-mc-power-savings and usb-autosuspend. - don't lock the cpufreq to the
lowest frequency: this is bad for power usage. - rfkill on the bluetooth device
(using a personal laptop-module). - lower (but not lowest) LCD brightness. -
with the specific module laptop-mode can tweak the power management of the
driver iwlagn but it uses the interface /sys/class/net/$IF/device/power_level;
I use to do a further 'iwconfig wlan0 power on' with great difference (using a
personal laptop-module).
Current issues:
Nvidia/Intel hybrid graphics switching.
This machine is the successor of the SZ premium series, and has a Dynamic
Hybrid Graphics system that will enable/disable the nvidia graphics card using
a software "hot" switch instead of a hardware "cold" switch (SZ series).
http://vaio-online.sony.com/prod_info/series1/z/interview_Z/index_05.html
In the way it's shown in the video, it seems like Windows Vista does the
equivalent of a "gdm restart" in Linux when switching from the nvidia graphics
card to the integrated intel card (to confirm).
eva-brucherseifer reports that Sony's DSDT is significantly different from
previous models, probably to enable special hardware support e.g. for the
graphics card switching, enabling/disabling the 3G module and more. Any further
input here is welcome.
DSDT is an acronym for Differentiated System Description Table. The table
contains the Differentiated Definition Block, which supplies the information
and configuration information about the base system. It is always inserted into
the ACPI Namespace by the OS at boot time. Unfortunately, many hardware vendors
and OEMs are not capable of supplying fully functional tables.
For laptops like the Sony Vaio Z series, there is currently Linux support for
cold switch of the graphics card:
Load Eva's sony-laptop module with speed_stamina=3. In the file called
/etc/modprobe.d/sony-laptop.conf add the following line:
options sony-laptop speed_stamina=3
Then boot with this kernel parameter (use the quotes):
acpi_osi="!Windows 2006"
Just put it in the kernel command line of your boot manager.
Now you can switch between stamina and speed without booting to Windows, but
your laptop have to be completely powered off, not rebooted.
Nvidia driver overwrites libglx.so and libGL.so.1 with symbolic links like
mentioned above. So before installing nvidia driver, backup the current
libglx.so und libGL.so.1 to libglx.so.INTEL/libGL.so.INTEL. If you have already
installed nvidia, you can get the original files from "xserver-xorg-core"
package, respectively "libgl1-mesa-glx".
For loading the correct xorg.conf, this little script needs to run before
starting xserver:
#!/bin/sh
lspci | grep "00:02.1"
if [ $? -eq 0 ]; then
* cp /etc/X11/xorg.INTEL /etc/X11/xorg.conf ln -sf /usr/lib/libGL.so.INTEL
/usr/lib/libGL.so.1 ln -sf /usr/lib/xorg/modules/extensions/libglx.so.INTEL
/usr/lib/xorg/modules/extensions/libglx.so
else
* cp /etc/X11/xorg.NVIDIA /etc/X11/xorg.conf ln -sf
/usr/lib/libGL.so.185.18.08 /usr/lib/libGL.so.1 ln -sf
/usr/lib/xorg/modules/extensions/libglx.so.185.18.08
/usr/lib/xorg/modules/extensions/libglx.so
fi
To have the right screen resolution when using the nvidia card on the Linux
Sony Vaio Z-series: If your resolution is 1600x900, then on the nvidia side I
have added the DPI to force it to the intel value:
Section "Device"
Identifier "Configured Video Device"
Driver "nvidia"
Option "UseEDIDDpi" "FALSE"
Option "AddARGBGLXVisuals" "true"
Option "DPI" "96 x 96"
EndSection
(For brightness control, one can add shortcuts for low, medium, high brightness
through nvidia driver commands.)
To get the speakers to shut when using the headphones plug, add this line to
"/etc/modprobe.d/alsa-base":
options snd-hda-intel model=sony-assamd
(Another user proposes "model=hippo" instead to make a "Headphone" slider
appear in alsamixer.)
To get the microphone working, create a file (by root or using 'sudo') in
/etc/modprobe.d/ with a line like
options snd-hda-intel model=toshiba-s06
then reboot (or unload and reload the module).
The jack for external microphone works using:
options snd-hda-intel model=sony-assamd
in a file in '/etc/modprobe.d/'.
Troubleshooting for Sound/Mic You can check for your default mixer by going to
System>>Preferences>>Sound. After you have the right mixer selected (You can
choose between HDA Intel, OSS, or Alsa options), you can select "Open Volume
Control" by right clicking the Volume applet, and make sure that in "Options,"
the "Input Source," is 'Int DMic'. (Attention: Digital-Capture-Source starts
muted by default. You may have to "un-" mute it by hand, depending on your
choice of mixer.)
Suspend/hibernate reported to work: a) with this kernel => 2.6.27-11-generic #1
SMP Thu Jan 29 19:24:39 UTC 2009 i686 GNU/Linux b) through powersaved via
kpowersave (KDE). c) Trying the instructions here:
http://www.claudiocamacho.org/tech/sr11m_debian.php#s4s15
You can use this script to bring back the backlight settings after wake-up,
instead of the simple "echo mem > /sys/power/state". It restores the original
display settings after wakeup, especially the backlight, which otherwise is set
to the highest value (at least on my system). It assumes that Eva's sony-laptop
module is installed.
The Fingerprint Reader does work with configuration based on work by
eva-brucherseifer:
http://www.basyskom.org/~eva/log_installation_vaio_z21vnx.htmlEva's work
(Please realize that fingerprint readers in Linux in general do not offer any
added security for your machine, and may not be the best choice for functions
such as logging into one's system)
To switch on/off the 3G device, There is now support in the sony_laptop kernel
driver and to get it work with hsoconnect. For a more detailed installation
summary, see this page:

Bluetooth (Gnome, Ubuntu, specifically) http://blueman-project.org/ Using
Blueman package instead of gnome-bluetooth will give much better results. It
allows one to shutoff bluetooth completely from the gui, and device browsing
and tethering is also much improved.
For Ubuntu Jaunty 1) Add Source deb http://ppa.launchpad.net/blueman/ppa/ubuntu
jaunty main
2) Install Blueman sudo apt-get install blueman

submit the following info:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/283401 1. Please include
the output of the command "uname -a" in your next response. It should be one,
long line of text which includes the exact kernel version you're running, as
well as the CPU architecture. 2. Please run the command "dmesg > dmesg.log"
after a fresh boot and attach the resulting file "dmesg.log" to this bug

attach the resulting file "lspci-vvnn.log" to this bug report.
Unsolved/Pending Bugs:
One could disable the hal polling on the CD drive but actually there is a bug
in it (https://bugs.launchpad.net/ubuntu/+source/hal/+bug/358390).
Optic DVD unit: it should be possible to use ACPI to turn it off, but nobody
has found how yet.
Firewire: unloading the module may power off the device (unconfirmed).
Reboot problems. (MARKED SOLVED: UPDATE VAIO BIOS THROUGH YOUR WINDOWS
INSTALLATION, SEEMS TO FIX HANG DURING REBOOT) *It freezes in the last stage of
the process (more info needed, file a bug in http://bugs.launchpad.net).
The Pro Magic Gate slots for memory cards don't work neither.
Issues in getting gsynaptics to work with touchpad (more info needed, file a
bug in http://bugs.launchpad.net).
The Intel driver also has a problem, reported here:
