No dash nor window title bars on unity after upgrate from precise to trusty

[Bruno Medeiros]

I've upgraded from precise to trusty a few weeks ago and I'm not able to use unity anymore. If I choose "Ubuntu" on lightdm, I got only my desktop screen, with no dash nor top bar, just my desktop icons. If I open any window, The window appears with no title bar.

To report this bug, I typed Ctrl + Alt + T, and used apport-bug, which opened the browser. I'm not able to switch back to the terminal right now I'm writing this description, thus alt+tab doesn't work too.

Just let me know if you need more info.
