In Ubuntu 11.04 (Natty Narwhal):
- Click the far top-left button to bring up the search dialog.
- Type “login” without the quotes and click on “Login Screen”.
- Change “Select Ubuntu as default session” to “Select Ubuntu Classic as default session”.
- Log out and back in.
Congratulation, you have removed the abomination. Prepare for 11.10 where they will no doubt remove Ubuntu Classic as an option.
Looks like I called it correctly. Didn’t have to be psychic for that one.
