Ubuntu – Cannot pass the login screen after upgrade to 12.04 from 11.10


I just performed the upgrade from Ubuntu 11.10 to Ubuntu 12.04 LTS. The updater downloaded all packages but a few ones that the system said were already installed. When asked for it, I chose to install the new maintainer's version of grub.

Now after that my system start up to the login page, some images won't load. Moreover, after I try to login, the graphical instance does not load, it just sits there showing the mouse pointer and nothing else.

I had the same problem. This is how I solved it (parts only in German, sorry; try e.g. Google Translate):

  1. chroot: http://wiki.ubuntuusers.de/chroot/Live-CD

  2. Look for the post of bowman Mai 2011 12:52: http://forum.ubuntuusers.de/topic/daten-retten-mit-live-cd-2/#post-2922047

  3. Run the following commands in a Terminal:

    sudo apt-get clean
    sudo apt-get update
    sudo dpkg --configure -a
    sudo apt-get -f install
    sudo apt-get upgrade
    sudo apt-get dist-upgrade
    sudo apt-get install --reinstall ubuntu-desktop

This did the trick.
