Yesterday, we told you that a 2D version of Unity will be available for computers which does not have hardware capable of 3D acceleration. Today a PPA containing the packages for Unity 2D has been created for early adopters to test it. The package itself is called Unity-Qt and the PPA contains packages for both Maverick and Natty.
Before you install it, keep in mind that this is an experimental package and could cause problems. So, install it only if you are willing to take that risk and cannot wait to see the new UI.
So, to install Unity 2D, open the Terminal (Applications > Accessories > Terminal). Then add the PPA with the command below:
$ sudo add-apt-repository ppa:unity-2d-team/unity-2d-daily
After that update the software list.
$ sudo apt-get update
Finally install Unity-Qt.
$ sudo apt-get install unity-qt-default-settings
After the installation, log out from your current session. In the login screen, you will see “Unity Qt” in a drop-down menu. Pick that and login again. You should have the new UI now.
And if you run into a bug, you can report it here.
