14.10 - Problem with Unity remains

I have a problem with Ubuntu 14.10. It doesn't load Unity, the Launcher, the Dash, etc.
I followed the steps given here, but the problem remains. I would be grateful if someone could help me.

If nothing worked for you , try loading ttyl by pressing ctrl+ alt + f1 and login in to see if any error is prompted and try to resolve error from there.

Or if even that doesn't work you can always create a new user from the terminal.

sudo useradd -m username

sudo passwd username
