Unity 2D on Ubuntu 9 comments

Ubuntu Unity is a desktop experience designed for efficiency of space and interaction. It maximizes usability and minimizes complexity. Everything is available just 1 click away and almost everyone enjoys working with it. But the problem is, you cant get Unity working everytime on your computer because it needs 3D effects enabled by-default. That means … those who are having low config computers, cant run Unity ? No, Unity 2D is here to the rescue. Unity 3D as we know is going to be the default interface for Ubuntu 11.04 Natty Narwhal. If you dont want to use Unity 3D or you are unable to use it, then just get yourself Unity 2D with Gnome in parallel.

Installing Unity 2D

Open the terminal and type this PPA to get unity 2d working on your desktop with Ubuntu 10.10 or Ubuntu 11.04.

sudo add-apt-repository ppa:unity-2d-team/unity-2d-daily
sudo apt-get update
sudo apt-get install unity-2d

After the installation, all you need to do is logout/reboot and when you reach ‘Login screen’, select to boot into ‘Unity 2D’ session rather than ‘Ubuntu Desktop’ session which is by-default selection. And thats it. You are now in Unity 2D without losing anything in your Gnome 2.32 desktop or Gnome 3.

Unity 2D First Look

At first Unity 2D looks almost like Unity 3D but its lighter and faster. There are no 3D effects enabled by-default taking much resources from your system ,so things are darn fast. The Panel is translucent with Ubuntu Netbook like interface. Its more polished and stable than 3D. So if you want to test Unity, safely Unity 2D is a way to go. Take a look –

Unity 2d vs Unity 3D

Unity 3D has got all those cool 3D effects enabled by-default that takes too much of system resources. Those who dont have much system power, cant run Unity 3D at all as it requires 3D effects enabled for Compiz to work. But Unity 2D is not like that, it can run on any system whether it has got 3D effects or not. It works on everything ranging from old computers to Netbooks to Desktops. Unity 2D as compared to Unity 3D is

  • Lighter
  • Faster
  • Easier to use
  • More polished
  • Stable
  • Flexible

So, Unity 2D is a way to go. It can easily work on Virtual machines too. So if anyone willing to use it on hypervisors is raedy to go. Just hit the PPA in the terminal and enjoy Unity.

For any queries regarding Unity 2D or 3D, or any other regarding Ubuntu, ask here freely.

Njoy !

    Unity 3D is a mess with intel GMA945 GPU and suffers from serious screen lag and delays
    under Unity 2D. I’m sure when this will be addressed and fixed.

  • For intel-945 Chipsets only, we would recommend you to stick with Gnome 2.32.

    homunculus@Aspire-4750G:~$ sudo apt-get update
    E: Could not get lock /var/lib/apt/lists/lock – open (11: Resource temporarily unavailable)
    E: Unable to lock directory /var/lib/apt/lists/
    E: Could not get lock /var/lib/dpkg/lock – open (11: Resource temporarily unavailable)
    E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

    why i have this happen??

  • You might be running aby other software installation or update alongside
    Also it might be Synaptic Package Manager
    Close them if they are running and then run it again
    sudo apt-get update is same as going to update manager and clicking refresh button

    ok,thanks.. i have fix it..and now i have problem with my graphic card. the driver detect but i can’t activate it. im using nvidia gt 520m..

    sorry for my english

  • “Unable to lock /var/lib/apt” means apt-get was working somewhere while you were trying to install Unity 2D. Might be the Update manager of Ubuntu Sfotware Center. You cannot run more than 1 instance of apt at one time. Make sure to run only Terminal while install Unity 2D. you can try it again, this wont happen…

  • Please follow these instructions if you are having any problems regarding Hardware Drivers – http://www.linoob.com/2011/04/installing-hardware-drivers-in-ubuntu/

  • what about entering commands in the search box to raise a terminal ?

  • Did you ever find a solution? Are you still on Gnome 2.32, as Linoob recommended? Or did you stop using Gnome altogether?
