Ubuntu 11.10 has been released with the new Unity – what shit! Unity Sucks!!!! The last release was semi-usable, but now – especially if you use different desktops – it is almost random. You have lost the task bar from the bottom of the screen and Alt-Tab scrolls through all Applications on all Desktops – not just the Desktop you are using. Ahhhh…..!
But I did find a few things you can do to make it better… The first being install Gnome Shell instead of Unity
sudo apt-get install gnome-shell
and then select it on startup as the interface to use.
