I was recently forced to upgrade to 12.04, one of the latest software updates cratered 10.04. I decided to install Gnome using the instructions here: https://www.ibm.com/developerworks/c...cise12?lang=en
That machine no longer boots. I really don't have time to rebuild it this weekend, but it looks like I have no choice. In the past, Ubuntu has been solid. I'm beginning to worry.
For the record, I tried safe mode and let it repair packages. It boots part way and stops. Maybe a fresh install will work better.
