I am new to Ubuntu and just installed Ubuntu 14.04.1.
After using it for 2-3 days I just installed the plugins and was experiencing the new features.
I've never worked on Ubuntu before. but after the update for Utopic Unicorn that is 14.10, the side bar and the menu bar are gone and before that I rebooted the system because the system hung after the first boot up after the update.
Since then they have disappeared. The only thing that I can see is the song that I made a shortcut on the home screen.
I can move my cursor and open up the settings using the change desktop background option. The music is also playing just fine.
I am unable to open the terminal using ctrl+alt+t, but I can access TTY1.
Please tell me a solution for this. I am stuck. I'd also like to mention one thing, when I log in as guest all the menu bars and side bars appear.
I don't want to reinstall the whole system, please give me a solution.
