    Unity won't launch after 12.10 installation


    After a new installation of 12.10 on a Lenovo x120e and a restart the Unity shell won't launch.

    Installation of 12.10 amd64 yesterday went well. I turned the computer off for the night and when I turned it on this morning I was presented with the login screen. When I enter the password the screen flashes black and returns to the login screen. I'm using the right password because if I enter an incorrect one a message in red font tells me so and the login screen remains.

    If I choose guest access the computer brings me to the desktop but without the unity shell. A right click will bring up the New Folder, Change Desktop, etc. menu. Ctrl-Alt-T will open terminal. I tried "sudo xinit --:1" but I can't use sudo on a guest account.

    Any ideas?

    Boot on recovery mode (hold "shift" key down at bios end process)

    Run this in terminal
    it will test your hardware, make sure there is a YES in unity 3d support

    If you have support for Unity and terminal access try the following.
    setsid unity
