After installing the new Ubuntu 15.04 Vivid Vervet, one of the top things to do is to install audio/video codecs and enable DVD playback.

Due to legal constraints in many countries, Ubuntu does not include these codecs to play mp3, movies, and DVDs out-of-the-box. But we can easily get them from the default repositories through Ubuntu Software Center.

1. Install the codecs to play common audio and video file formats:

Open Ubuntu Software Center, search for and install ubuntu-restricted-extras package. After that, you should be able to play your musics and movies through the default multi-players.

2 The previous step also installs libdvdread4, library to read DVDs. If not, install it from Ubuntu Software Center.

3. To play encrypted DVDs, you also need the libdvdcss2 library by installing it via below command in terminal:

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

You may need to set the region code for DVD drive if it is still not working, by running below command in terminal:

sudo apt-get install regionset && sudo regionset

The default file browser in Elementary OS Freya uses single-click to open files and folders, though there’s no option to change this preference.

For those who would like to use double-click to open an item in the file browser, there’s a graphical configuration tool called Elementary Tweaks that may help.

1. Install Elementary Tweaks in Freya

The developer is maintaining a PPA with the latest packages for this tool.

Though the 14.04 build is failed at the moment of writing this tutorial, we can download an earlier version at PPA’s ftp download page:

Download Elementary Tweaks (.DEB)

Depends on your OS type, select download:

  • For 64-bit eOS Freya, download:
    • elementary-tweaks-dbg_x.x.x~ubuntu14.04.1_amd64.deb
    • elementary-tweaks_x.x.x~ubuntu14.04.1_amd64.deb
  • For 32-bit eOS Freya, download:
    • elementary-tweaks-dbg_x.x.x~ubuntu14.04.1_i386.deb
    • elementary-tweaks_x.x.x~ubuntu14.04.1_i386.deb

Then install them one by one, in below order, by opening the .deb package with Software Center:

  • elementary-tweaks_x.x.x~ubuntu14.04.1_i386/amd64.deb
  • elementary-tweaks-dbg_x.x.x~ubuntu14.04.1_i386/amd64.deb

2. Disable single-click and enable double-click

After installing Elementary Tweaks, open System Settings from the dock at the bottom of your screen and then click the Tweaks icon.

In the next page, select Files from left pane, and finally disable Single Click by clicking the toggle.

When the file opens, replace values of Icon and Exec with file path to the icon and run_game.sh script.
