I am very new with Ubuntu, been a Windows user since the beginning.
Yesterday I did a recommended software update on my laptop running Ubuntu 13.04, upon restarting I can't login at all. The login screen appears, I can move my mouse around but I can't click anywhere to login, not my username, not on the power button in the top corner of the screen, nowhere.
I installed Gnome 3.8 as a shell and everything was going fine, I guess, until I did the update. One thing though, while it was updating, a message appeared saying that some updates couldn't be applied due to some components that were not downloaded properly.
Is there a way to repair Ubuntu or do I have to re-install everything from scratch?
