Install LinuxMint12 extensions Mate & MGSE in Ubuntu 11.10

Linux Mint 12 RC comes with two option of desktop environment: One built with GNOME 3.2 and MGSE and other with GNOME 2.3 and MATE. In this post we will show how to Gnome shell extenstion Mate for LinuxMint in Ubuntu11.10.

First if you didn hear about ‘Mate”, it is a fork of Gnome 2 which is compatible with Gnome 3. Thanks to MATE, you can run both versions of Gnome on the same system.MATE is brand new, it’s not completely stable yet, and it’s missing a few parts. It’s being actively maintained and with close collaboration between the MATE developers and Linux Mint. With time the project will gain maturity and provide users with a traditional and solid desktop experience.(1)

For “MGSE” (Mint Gnome Shell Extensions) is a desktop layer on top of Gnome 3 that makes it possible for you to use Gnome 3 in a traditional way. You can disable all components within MGSE to get a pure Gnome 3 experience, or you can enable all of them to get a Gnome 3 desktop that is similar to what you’ve been using before. Of course you can also pick and only enable the components you like to design your own desktop.(1)

You can install Mate and MGSE extension (LinuxMint new Menu) in Ubuntu 11.10 by using the Mintrespository:

1- Open terminal and enter the following commands:

sudo gedit /etc/apt/sources.list

2- Now add the following line at the bottom of the file:

deb lisa main upstream import

3- Now refresh repository:

sudo apt-get update

4- When refreshing the repository you will got the following error:

 W: GPG error: lisa Release: The following signatures couldn't be verified because 
the public key is not available: NO_PUBKEY 3EE67F3D0FF405B2

5- This command will correct the error above:

 sudo apt-get install linuxmint-keyring 

sudo apt-get update

Now open ubuntu software center and check if Mint repository has been added:



6- Now install Mint Mate using the followng command:

sudo apt-get install mint-meta-mate

Remember since Mint repository was added, you can install any Mint extension, for example to install the new Mint MGSE extension in Ubuntu 11.10, just open Ubuntu software center and search Mint MGSE.

 Now to enter to the new Mate enveriment, logout and choose to Login into Mate:

    And once you login to MATE and see it’s not ready yet, log back out and back to business.

  • Kyle

    If you install the MGSE’s then you need to enable them in "Advanced Settings" once you log back in.

    if have the same problem.
    i removed mint-meta-mate and linuxmint-keyring.
    then i deleted the line from /etc/apt/sources.list.

    my software-center doesn’t start.
    when i start software-center in a terminal i get following message:

    Traceback (most recent call last):
    File "/usr/bin/software-center", line 149, in
    from import SoftwareCenterAppGtk3
    File "/usr/share/software-center/softwarecenter/ui/gtk3/", line 49, in

    lsb_release -a prints:
    Distributor ID: LinuxMint
    Description: Linux Mint 12 Fluxbox
    Release: 12
    Codename: lisa

    that’s the reason why software-center doesn’t work

  • ossioz

    i got it:

    sudo gedit /etc/*release
    and change everything to:
    DISTRIB_DESCRIPTION="Ubuntu 11.10"

    sudo gedit /etc/*issue
    and change everything to:
    Ubuntu 11.10 n l

    and now it works ;-)

  • ossioz

    Ubuntu 11.10 n l


  • ossioz

    It has to be DISTRIB_CODENAME=oneiric

    now software-properties-gtk also works

    Rather than messing with Ubuntu to try to undo their truly awful dis-Unity interface, it made more sense to me to just install Linux Mint. (I don’t trust Ubuntu any longer because they just don’t understand users who need to access 30 or 40 apps per week the way I do.) I just installed Mint "Lisa" (very tasty!) and the installation offered to keep my Ubuntu 11.10 data. All went perfectly. Even Code-Browser (a fabulous editor for writing your code using hypertext folding) carried over. If I were you, instead of stealing one or two good things from Mint, just get rid of Ubuntu altogether.

    I followed these steps and when I log into MATE even the gnome-panel does not load up. And once I run gnome-panel it does not look anything similar to Mate. What could have gone wrong? Also is running gnome-panel the correct thing?

  • Blast

    Excellent.. I was wondering when I would be able to do this.. I really like Mint, but version 12 is kind of buggy on my Dell Latitude E6420

  • BitingBoy

    Do you know Mint is actually based on Ubuntu?

  • Theunpropro

    Thanks for the info.
