running Unity 2d in Xubuntu 12.04

  • 772

I'm trying to run Unity 2d in xubuntu, I installed the packages but when I try to run it I get

[FATAL] Settings schema 'com.canonical.Unity' is not installed

How can I get it to run? I'd like to install as little stuff as possible.

xubuntu

    I think unfortunately you will have to install more dependencies, and the one you are missing is gnome-session, without which unity 2d can't run, and you get the error message you received. This is actually detailed at Launchpad; installing unity 2d manually from Synaptic does not automatically pull in the correct dependencies.

    Running an apt-cache rdepends unity-2d proves this:

    unity-2d
Reverse Depends:
  unity-2d-dbg
  unity-2d-common
  libunity9
  unity-2d-dbg
  unity-2d-common
  ubuntu-desktop
  libunity9
  gnome-session
 |gnome-session

    If you don't want absolutely everything that gnome-session includes, you could try installing it with the --no-install-recommends flag and this will install just the essential elements needed for unity-2d.

    Run in terminal

    sudo apt-get install gnome-session --no-install-recommends

    It should not be necessary to install the ubuntu-desktop package as well, but keep that in mind if all else fails.

    Using unity-2d should now be possible and it should be a login option at the Xubuntu screen and if you have any visual defects in it is also worth installing the following, according to this Launchpad report.

    sudo apt-get install light-themes ubuntu-mono ubuntu-wallpapers-precise gnome-themes-standard

    As the two bug reports at Launchpad have proven, you do need to install a fair amount of things to run unity-2d on Xubuntu.

  2. Check out your dependencies, when I saw this in the past I used dpkg to list them and it turns out some of the dependencies were wrong and somehow unity-2d-places and unity-2d-spread were not installed.

  3. I think you should install ubuntu-desktop package if you want to be sure to have all packages for unity:

    sudo apt-get install ubuntu-desktop
