ubuntu-tvuninstall
Before I jump into the deep end of the pool and install this wonderful looking media app. My concerns are it's stability and my ability to revert my system back to it's pre-ubuntuTV state.
Are there any detailed 'un-install' instructions? or is my best bet to just do a complete backup and restore if anything goes amuk?
You can install Ubuntu by downloading it, buning it on a cd/DVD or a USB.
install Ubuntu, When booted in Ubuntu follow the steps bellow.
step 1
Remove the Video Lens that comes with the YouTube scope or else there will be conflicts:
sudo apt-get remove lens-video
Install Ubuntu TV using the test PPA
sudo add-apt-repository ppa:nilarimogard/test3
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install unity-lens-video
step 2
To generate previews for your videos (which should be placed under ~/Videos/unity/local/featured ), use:
edit the ~/Videos to wherever you have your Videos
/usr/lib/unity-lens-video/create_tmb.sh ~/Videos
step 3
Logging in to Unity 2D won't work and you must run Ubuntu TV from the session you're currently logged in so open a terminal and copy/paste the following commands:
gsettings set com.canonical.Unity2d form-factor tv
if you were running Unity 2D already:
killall unity-2d-{panel,places,launcher,spread} && killall unity-2d-{panel,places,launcher,spread}
for unity 3d / Gnome-shell
metacity --replace &
to run ubuntu-tv copy/paste this in gnome-terminal
unity-2d-shell -opengl
to Close ubuntu-tv run this
for unity
unity --replace
for gnome-shell
gnome-shell --replace
To revert the changes
sudo apt-get install ppa-purge

Ubuntu TV is a flavor of the Ubuntu operating system intended for use on smart television sets. While with traditional televisions you flip between channels of programmed content, Ubuntu TV will provide an interface to choose shows and movies à la carte. It will also be internet enabled, letting you browse the web, use rich media applications, record shows, and control remotely from a mobile device.
Above all, Ubuntu TV is its tagline: TV for human beings. The televisions of 2011 are incredibly complex: they come with input cables, set-top boxes, and controllers with eighty buttons and as many modes (AV1, AV2, HDMI... do these look familiar?). Ubuntu TV aims to be a revolution in ease of use.
The great differentiating feature of Ubuntu TV is its commitment to putting all these features in one easy-to-use interface. Other smart television products fragment the user experience with apps. Want to watch a video? You must check Netflix, Hulu, Amazon, Youtube, and your cable listing to see which service has it. Ubuntu TV has one searchable, browsable interface that consolidates content from dozens of different sources, and makes it easily accessible to you.
Ubuntu TV is an open platform based on the Unity interface, the Ubuntu One online storage service, and software written by such giants of the software industry as Intel and Nokia, as well as a community of thousands of passionate developers working for software freedom, a movement to free society from the dangers that closed platforms pose to privacy and technology working for users, not against them.
Ubuntu TV is not yet widely available, but is expected to ship on television sets by the end of 2012. You can watch an early version of Ubuntu TV in action here, and read more about its particular features and experience here.
If you are a developer or interested technical user, the source code of Ubuntu TV is already available. If you are an OEM or content provider, the company developing Ubuntu TV would love to discuss the future with you.

If it has been packaged correctly, by installing UbuntuTV using the deb package from webupd8, you should (in theory) be able to ppa-purge the PPA and this would restore your system.
i.e.
If you see the following error message
sudo: ppa-purge: command not foundthen install theppa-purgepackage:However, as all PPAs are potentially destructive, a drive-image would be prudent to make, especially as UbuntuTV makes underlying changes to Ubuntu2D.
I've done some limited testing installing and ppa-purge the package. From initial testing, ubuntu-2D works correctly after uninstalling - i.e. the same packages upgraded to v5 are downgraded to v4.x that is standard in oneiric.
However - the warning should be still applicable - drive-image your hard-drive. Use it as an excuse to perform that regular backup procedure we all keep putting off... :)
