Ubuntu is just about the worst Linux distro. available these days. Canonical who produce Ubuntu have become arrogant and ignored users needs however well voiced across the many Forums that make reference to Ubuntu. For example Ubuntu 11.10 doesn't offer the classic GNOME Desktop and it doesn't include the Synaptic Package Manager despite the fact many users did not want these changes. I used to have much time for Ubuntu starting with Ubuntu 6.10 finishing with the last decent release which was Ubuntu 10.04 LTS
I recommend uninstalling Ubuntu and working with a different distro.
