Autologin Ubuntu 2d on Oneiric Ocelot

The new Ubuntu 11.10 Oneiric Ocelot used Unity or Ubuntu 3D as default windows manager. For low-powered computer or laptop, it will be run slowly. The alternative is change the default Ubuntu Unity 3d (in the login screen it is called "ubuntu" only) windows manager to ubuntu-2d. But, each login you must set this setting. Just try this method to make ubuntu-2d be default your windows manager,

in the file /etc/lightdm/lightdm.conf you have to change the user-session to ubuntu-2d. In ther terminal, just type,
sudo nano /etc/lightdm/lightdm.conf
and fill the blank user-session to ubuntu-2 like this,

and leave other options as default. Just for your information, The ubuntu-2d is implemented using Qt/QML for the UI portions of Unity, while utilizing the existing Unity core components, like indicators, bamf, dee, uTouch and places.

This screenshot show you the lightdm.conf in which you must change the setting of user-session as I mentioned above.
