      Ubuntu 12.10

      Ubuntu 12.10 has a lot the same as its predecessor. After installation you need some tweaks to make it perfect. 




      DVD

      First install the ‘libdvdread4‘ package from the Ubuntu Software Center. As the name implies this package adds the necessary libraries needed play DVDs.

      Install libdvdread4 in Ubuntu

      Once libdvdread4 has fully installed you need to run the ‘CSS’ script included with the package. This allows the ‘Content Scramble System‘ used on virtually all commercial DVDs to be ‘unscrambled’ and read.

      Open a new Terminal window and run the following command carefully, and inputting your password when prompted.

      sudo /usr/share/doc/libdvdread4/install-css.sh

      The script will take a few seconds to complete.

      Once done you’ll be able to playback and navigate DVD menus in most applications, including Ubuntu’s default movie app Totem, and a host of others, including perennial favourite VLC. 

      Music

      For legal reasons Ubuntu can’t provide certain music and film codecs ‘out of the box’.

      That’s not to say they aren’t available or easy to install – the Ubuntu installer gives an option to do this during installation.

      But if you didn’t notice that option – and it is easy one to miss – there’s no need to panic: the most common music and video codecs can be installed through the Ubuntu Software Center.

      Hit the button below to begin.

      Install Third-Party Codecs  

      Other Multimedia
      Start the Ubuntu Softwarecenter and query: restricted ubuntu 

      Click on Ubuntu restricted extras and install them.


      (Screenshot is of Ubuntu 12.10. In Ubuntu 12.04, this window looks only slightly different)

      With that, you've installed ubuntu-restricted-addons. But even so, it's still necessary to install ubuntu-restricted-extras as well. Because that contains some extra software that you need, too.

      Note: the installation of ubuntu-restricted-extras will necessitate the removal of two previously installed codecs. Simply agree to that proposal.

      Note: don't install any more gstreamer plugins! Now you've got all the gstreamer plugins you need (you already installed a bunch of them as part of the package "Ubuntu restricted extras"). When you install even more gstreamer plugins, they may cause malfunctions.

      When it's finished, use the query VLC 
      and install it.
      When it's finished, use the query SMPlayer
      and install it.
      When it's finished, use the query Audacious
      and install it

      Note: do not install the Mozilla plugins (Firefox plugins) for VLC or Mplayer! The default Totem plugins perform much better in rendering video's on websites.
       
      When it's finished, use the query synaptic
      and install the synaptic package manager.
      After that close Ubuntu Software Center.

      Now just to be sure check for wrong Flash players and remove them

       Perform a check on the possible presence of wrong Flash players and remove them:

      Start synaptic and search first for swfdec and then for gnash 

      When found, mark them for "complete removal", and then press Apply.

      Hardware drivers

      Drivers to use your graphics with 3D accelaration are easily installed:

      To do this, open the Software Sources app via the Dash (or through System Settings) and hit the ‘Additional Drivers‘ tab.

      Note that the open source nouveau driver fort Nvidia cards works quite good when you 've got a fast machine. (The Nvidia closed source drivers gave big troubles on my system, allthough they don't in earlier versions of ubuntu where they function quite well. (resolution troubles and crashing programs)

      Remove the Amazon shopping lens

      Not everyone will appreciate one of Ubuntu 12.10′s more controversial new features – that of Amazon product suggestions appearing in the Dash as you search for apps.

      Remove it from the terminal with this command:

      sudo apt-get remove unity-lens-shopping

      Read more about this lens here

      Alternative way to install the playfunction of encrypted DVD's

      You need to install  libdvdcss2 

      This is available in the third-party software source of Medibuntu, which isn't enabled by default. Because you can use an installation script for libdvdcss2, you won't have to enable Medibuntu permanently. That'?s good, because their servers are very slow and tend to slow down any refreshing of the repository lists in an update proces.

      Open the terminal and copy and paste this blue text into the terminal:

      sudo /usr/share/doc/libdvdread4/install-css.sh

      Press Enter. When asked, type your password and press Enter again. Your password will remain entirely invisible, not even dots, this is normal.

      When the installation is finished, you can close the terminal window.

      Option: non-free-codecs, w32codecs or w64codecs

      Although not needed most times you can still install the non-free-codecs and w32codecs or w64codecs from the Medibuntu repository:

      Open the terminal and 
      copy and paste this entire blue text block into the terminal:

      sudo wget --output-document=/etc/apt/sources.list.d/medibuntu.list http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list && sudo apt-get --quiet update && sudo apt-get --yes --quiet --allow-unauthenticated install medibuntu-keyring && sudo apt-get --quiet update

      and press Enter. Enter you invisible password.

      Then in the terminal (use copy/paste in order to avoid errors): 

      32bit:
      sudo apt-get install w32codecs non-free-codecs libdvdcss2

      64 bit:
      sudo apt-get install w64codecs non-free-codecs libdvdcss2

      Install indicators

      start Synaptic. (if it isn't installed: sudo apt-get install synaptic)

      search for indicator and se+lect the indicators you need on the taskbar.

      Make unity more responsive

      Unity 2D has been dropped in Ubuntu 12.10, which means some low end systems may face occasional lags while using Unity and searching from Dash. Fortunately, there is a work around for those troubles by slow speeds and lags. For this, you need to add the following line in your ~/.xprofile file. If the file doesn't exist, create it. (it is in your home directory, start gedit and create .xprofile)

      export UNITY_LOW_GFX_MODE=1

      The line enables low graphics mode in Unity which disables some fancy effects like active blur and transparency.

      Make Geeqie work again

      The imageviewer Geeqie didn't work anymore on my system. The proglem is found in the photos lens in unity. After removing this lens, geeqie wiil work again.

      sudo apt-get remove unity-lens-photos
