Warning! Article is a little bit outdated!
Warning! Use this instruction at you own risk!
You should definitly know what are you doing
(especially at "Fix kernel cmdline" section) else
you may get unbootable or broken system!
Notes:
1) 12.10 should have fixed nvidia-tegra driver package. So it is not needed to remove it.
2) some links are outdated.

==== ubuntu 12.04 ====
=== Fix kernel cmdline for 3.1.10 kernel ===
**Important!** For ubuntu 12.04 you should add **console=tty1** to **cmdline** parameters in **/boot/bootimg.cfg**
This line need to be changed to this state (just example, not a working config):
cmdline = mem=512M@0M terapart=something root=UUID=anothersomething quiet splash console=tty1
Open **/boot/bootimg.cfg** in you favorite text editor and make changes.
sudo apt-get purge nvidia-tegra
sudo update-alternatives --remove arm-linux-gnueabi_egl_conf /usr/lib/nvidia-tegra/ld.so.conf
sudo update-alternatives --remove-all nvidia_drv
=== Kernel and driver installation ===
Remove previous nvidia-tegra installation
sudo apt-get purge nvidia-tegra
sudo update-alternatives --remove arm-linux-gnueabi_egl_conf /usr/lib/nvidia-tegra/ld.so.conf
sudo update-alternatives --remove-all nvidia_drv
Download and install kernel and driver packages
wget http://launchpadlibrarian.net/118260107/linux-image-3.1.10-6-ac100_3.1.10-6.9_armhf.deb
wget http://flie.no-ip.org:7080/ac100/deb/nvidia-tegra_16.1.0-0ubuntu3~fly2_armhf.deb
sudo dpkg -i linux-image-3.1.10-6-ac100_3.1.10-6.9_armhf.deb nvidia-tegra_16.1.0-0ubuntu3~fly2_armhf.deb
==== ubuntu 12.10 ====
First, check you kernel version. It should be 3.1.10-6.9 or later.
dpkg -l | grep linux-image-3.1.10
Update it if necessary
sudo apt-get install linux-image-ac100
=== Install nvidia-tegra drivers===
Remove previous nvidia-tegra installation
sudo apt-get purge nvidia-tegra
sudo update-alternatives --remove arm-linux-gnueabi_egl_conf /usr/lib/nvidia-tegra/ld.so.conf
sudo update-alternatives --remove-all nvidia_drv
Download and install new codecs and driver packages.
wget http://flie.no-ip.org:7080/ac100/deb/nvidia-tegra-ventana-codecs_16.0.0-0ubuntu1_armhf.deb
wget https://launchpad.net/ubuntu/+source/nvidia-graphics-drivers-tegra/16.2.0-0ubuntu3/+build/3907865/+files/nvidia-tegra_16.2.0-0ubuntu3_armhf.deb
sudo dpkg -i nvidia-tegra_16.2.0-0ubuntu3_armhf.deb nvidia-tegra-ventana-codecs_16.0.0-0ubuntu1_armhf.deb
//If you prefer you own kernel, inspect that you have CONFIG_TEGRA_AVP_KERNEL_ON_MMU=y and "CONFIG_TEGRA_NVAVP is not set" in kernel config.//
==== ubuntu 13.xx ====
Driver package is ok in 13.xx. Install it.
sudo apt-get install nvidia-tegra
Download and install codecs packages.
TODO: provide link to actual codecs package
==== Gstreamer tuninig ====
**gstreamer-properties** is a part of gnome-media package.
Run
gstreamer-properties
Insert parameters **nv_omx_audiosink** and **nvxvimagesink** to its place

(Button **Test** prodice "could not link ffmpegcsp0 to nvxvimagesink2" error, its dont work with this driver for some reason)
==== Finally ====
sudo reboot
Done! Now you can run totem and play videos with relativly high cpu load. At this time window and fullscreen playback working in totem.
[[http://www.dvdloc8.com/clip.php?movieid=12167&clipid=1|Example video - h264 720p trailer]]
Should play smoothly in totem, and you can compare it with mplayer -vo x11.
**Advice**: install **gstreamer0.10-plugins-bad** to ac3-encoded audiotracks playback.
=== Totem keyboard shortcuts: ===
F1 - Help
F9 - Properties
F11 - Full Screen
q - Quit
r - Zoom In
t - Zoom Out
o - Open
p - Pause
a - Change Format
f - (see F11)
h - Show/Hide Controls
> - Frame Advance from pause (This is the one I was looking for!!)
< - Return to pause point from frame advance
→ - Advance 1 min
SHIFT → - Advance 15 secs
← - Back 15 secs
SHIFT ← - Back 5 secs
↑ - Volume up
↓ - Volume down
Also, there is some other ways to play video in window mode
nvgstplayer -i file:///media/TOS_AC_AZ/Videos/example.avi --svs="nvxvimagesink"
gst-launch-0.10 playbin2 uri=file:///media/TOS_AC_AZ/Videos/example.avi video-sink=nvxvimagesink audio-sink=nv_omx_audiosink
for nvgstplayer run programm from terminal and leave focus on it to have control keys.
Check permissions and owners of /dev/nv* files if any problems. It should be 0660 root:video.
==== OpenGLESv2 ====
Also, you can install packages **mesa-utils-extra** and **glmark2-es2** to look at movings gears
es2gears
or run more complex benchmark
glmark2-es2
There is some [[games|]] [[http://ac100.wikispaces.com/%D0%98%D0%B3%D1%80%D1%8B|(even more games on russian wiki)]] running on ac100 via GLES2
Also check WebGL on [[http://www.khronos.org/webgl/wiki/Demo_Repository|Chronos]] or [[http://www.chromeexperiments.com/tag/webgl|Chrome Experiments]] in chromium running as
