...and here's in short how the Kinect should be working on Ubuntu 10.10 with an SSE3 enabled CPU (compare with previous post):

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install git-core build-essential libusb-1.0.0-dev libglut3-dev doxygen graphviz

cd ~/kinect
git clone https://github.com/OpenNI/OpenNI.git
cd OpenNI/Platform/Linux-x86/Build
make
sudo make install

cd ~/kinect
git clone https://github.com/boilerbots/Sensor.git
cd Sensor
git checkout kinect
cd Platform/Linux-x86/Build
make
sudo make install

cd ~/kinect
wget http://www.openni.org/downloadfiles/openni-compliant-middleware-binaries/stable/54-primesense-nite-beta-build-for-for-ubuntu-10-10-x86-32-bit-v1-3-0/download -O nite_ubuntu_x86.tar.bz2
tar xvjf nite_ubuntu_x86.tar.bz2

cd ~/kinect/Nite-1.3.0.17/Data

cp Sample-User.xml Sample-User.xml.BAK && chmod u+w Sample-User.xml && sed "s/insert key here/0KOIk2JeIBYClPWVnMoRKn5cdY4=/" Sample-User.xml.BAK | sed "s%xRes="[0-9]*" yRes="[0-9]*"%xRes="640" yRes="480"%" >Sample-User.xml
cp Sample-Scene.xml Sample-Scene.xml.BAK && chmod u+w Sample-Scene.xml && sed "s/insert key here/0KOIk2JeIBYClPWVnMoRKn5cdY4=/" Sample-Scene.xml.BAK | sed "s%xRes="[0-9]*" yRes="[0-9]*"%xRes="640" yRes="480"%" >Sample-Scene.xml
cp Sample-Tracking.xml Sample-Tracking.xml.BAK && chmod u+w Sample-Tracking.xml && sed "s/insert key here/0KOIk2JeIBYClPWVnMoRKn5cdY4=/" Sample-Tracking.xml.BAK | sed "s%xRes="[0-9]*" yRes="[0-9]*"%xRes="640" yRes="480"%" >Sample-Tracking.xml

sudo niLicense PrimeSense 0KOIk2JeIBYClPWVnMoRKn5cdY4=
cd ~/kinect/Nite-1.3.0.17
sudo ./install.bash

You have to enter the key
0KOIk2JeIBYClPWVnMoRKn5cdY4=
again.

Now checkout the examples in the directory

cd /home/ubuntu/kinect/Nite-1.3.0.17/Samples/Bin/
