I upgraded to 12.10 some days ago and now I'm unable to change between the environments. I currently have GNOME 3 (with extensions), KDE and, of course, Unity installed. The computer is a Lenovo G550.

In the login screen I can get into the menu where the DEs are listed, but I can't select one. I can't use a test account of mine, which used GNOME 3, because after I logged in X crashes/restarts. Unity works, but I can't switch from the broken GNOME 3 to Unity.

What did I broke during the upgrade and how can I fix it?

How will people upgrade from 12.10 to 14.04 after 13.04 is EOL?

Looking at https://wiki.ubuntu.com/Releases 13.04 will reach EOL in January 2014, while 12.10 will reach EOL in April 2014, therefore if a 12.10 user hasn't upgraded to 13.04 and subsequently to 13.10, there will be a 3 month period where a 12.10 user has a supported version of Ubuntu, but will be… >>> More
