I even restarted the computer, but to no avail.

Has something been changed so you cannot change away from Unity?
Should this tutorial be updated?

Your help will be appreciated.

I'm not aware of any change, but I notice you mention changing users when you selected the classic (no effects) session so if you have auto-login set you may still be booting into the original users DE choice. Maybe try setting auto-login to off in System Settings > User Accounts, then at login be sure to select the desired user and also the desired session.
