I installed Ubuntu Unity 12.10 on my Sony Vaio and it was working well, until somewhere after installing the updates and installing Unsettings, Cairo dock and Ubuntu-Tweek-Tool, a window displays saying that the system needs to restart.

After restart; Ubuntu starts loading, but it only loads terminal tty (it asks me for my user and password just as if it was the normal thing, but just in terminal. no visual interface).

  • What can I do? Please help!

What happens when you log into the console and run sudo service lightdm restart? –  phoibos Feb 1 '13 at 11:12
    
With Ubuntu 12.10 support ending in 4 days (April 18th) it may be more beneficial to download either Ubuntu 12.04, or Ubuntu 14.04 which will release on the 17th, and do a fresh install. I otherwise agree with the other two comments for starting a graphical session. –  Paul-92711864 Apr 14 at 14:31
