    Running GNOME Shell on top of Unity2D

    Youtube video (New)

    GNOME Shell + Unity2D http://www.youtube.com/watch?v=nW-PqT4fx0w
    Cinnamon + Unity2D http://www.youtube.com/watch?v=65wVYifJk-I

    *Important:

    + There has been an issue of prolonged loading time of DE because of LightDM. The solution is to use GDM instead of LightDM. A how-to can be found here http://www.webupd8.org/2011/07/how-t...ightdm-or.html

    + Restarting GNOME Shell causes HUD and Unity Dash to malfunction. Restarting only the Shell Theme (rt instead of r in Alt F2) is OK though.

    + When Logging out or Shutting down, try to use the menu of GNOME Shell. Otherwise, the gnome-session will likely hang (open System monitor and kill gnome-session in order to restart). This is because GNOME Shell in running on top of Unity, it is in control.

    *My customization

    Unity-2D


    Dconf-tools must be installed first

    Code:
    sudo apt-get dconf-tools
    + By default when you are going with GNOME Shell on top of Unity, tabbing the left <Super> key will bring up Overview. For people who don't like this, we can ship Overview to the right <Super> key.

    Code:
    dconf-editor
    Navigate to Org.gnome.mutter >> overlay-key >> change from Super_L to Super_R

    Log out and log back.

    + Do you know that by clicking on the launchers that have more than one opening window, a small Overview will come up (like an app-switcher)? If you are experiencing SLOW performance with this function (I mean slow, not ugly, because mine is also ugly for we are running in mutter, not compiz), follow this:

    Code:
    dconf-editor
    Navigate to com.canonical.unity-2d >> check use-opengl

    Log out and log back.

    + To change color of the Unity Dash:

    Code:
    dconf-editor
    Navigate to com.canonical.unity-2d >> averrage-bg-color >> change the color code (codes can be got from here by clicking on one of the color box and then clicking on the color wheel)

    + Stop showing apport (crash report dialogs). This will not disable crash reporting. We can still silently support Ubuntu.

    Code:
    dconf-editor
    Navigate to com.ubuntu.update-notifier >> uncheck show-apport-crashes

    How-to with GNOME Shell:

    1/ Install Gnome-tweak-tool (this will install all other necessary packages)

    Code:
    sudo apt-get install gnome-tweak-tool
    2/ Make sure you are in Unity-2d session, then type gnome-shell --replace in the terminal

    Code:
    gnome-shell --replace
    *To make this permanent, add that command line to start-up applications.

    3/ Open the link below and install the gnome-shell extension to auto-hide the top-panel of Gnome Shell, so we can see that of Unity-2D, which has Appmenu and other applets on it.

    https://extensions.gnome.org/extensi...anel-settings/

    After 15s or less, there will be a new icon on the top-panel of GNOME Shell. Click on it >> Visibility >> Autohide. All done.

    *Extras:

    Now you can enjoy the GnoUnity experience: move your mouse to the top edge to reveal the GNOME Shell panel, to the top-left corner to reveal Hot Corner, to the bottom edge to reveal notification bar; press the <super> key or Alt F1 to reveal GNOME Shell overview. There are some other tips if you really want to get into this weird type of desktop environment.

    4/ To be able to use many other extensions of GNOME Shell as well as to change the theme of GNOME Shell:

    Code:
    sudo add-apt-repository ppa:ricotz/testing 
    sudo apt-get install ppa-purge 
    sudo apt-get update 
    sudo apt-get install gnome-shell-extensions 
    sudo ppa-purge ppa:ricotz/testing
    (type N and press enter at the end of the process)

    Restart the shell (Alt F2 >> R >> Enter) or just log out and log back in.

    Other GNOME Shell extensions can be found here https://extensions.gnome.org

    GNOME Shell themes can be found here http://gnome-shell.deviantart.com/gallery/28081982

    5/ Customize Unity2D:

    Very good tips about Unity2D can be found here http://www.webupd8.org/2012/04/thing...ng-ubuntu.html (keep in mind that Unity2D is NOT the same as Unity3D) or you may want to take a look at the Important and My customization at the beginning of this thread.

    How-to with Cinnamon:

    1/ Install Cinnamon stable

    Code:
    sudo add-apt-repository ppa:gwendal-lebihan-dev/cinnamon-stable
    sudo apt-get update 
    sudo apt-get install cinnamon
    2/ Make sure you are in Unity-2d session, then type cinnamon --replace in the terminal

    Code:
    cinnamon --replace
    *To make this permanent, add that command line to start-up applications.

    3/ To further tweak Cinnamon:

    Code:
    sudo add-apt-repository ppa:bimsebasse/cinnamonextras
    sudo apt-get update
    And install the themes and applets that you like.

    My favorite part of the video is where at the end it says "A how-to can be found in the description below of this video", and the description of the video says "No description available."

    Why would you even want to do this, though? It just seems wrong.

    I agree but wonder how they did it, looks spooky

    Just added the tutorial. I was in a hurry this morning. Sorry about that. Should any errors occur ( though I tested this carefully before writing the how-to), please post them here. Thank you for your interest

    Just taking some guesses, but Unity2D panel (unity-2d-panel) and the Unity2D launcher (unity-2d-launcher) are separate programs and can be run in any DE you want. Not sure but the HUD feature may be tied in to either the panel or the launcher.

    I can guarantee you HUD and Unity Dash will be working in this case. Without them, there is no point of making up all these things, right
