I can't remember what I did but I don't think you have gnome shell in 11.10
sudo apt-get install gnome-shell
reboot and then you should have a choice at the login to choose Gnome classic
Yes, I was going to do that. Mind you the new software manager lists Gnome anyhow so I might just let the manager download and install it.
Got to say that, well, I likes the look of Ubuntu with Unity. A bit of a shock at first, but it seems to have taken a leaf out of the OSX book! Very easy to use. I know that a lot of the Ubuntu faithful are up in arms about Unity but my first impressions are that I could well work with this. Hell even LibreOffice opens my MS Office documents without a problem! All of my hardware and peripherals are recognised and that represents progress. This wasn't the case the last time I used Ubuntu.
Course, the real acid test is whether I can get PB working without any major headaches and with my levels of general incompetence anything is possible!
