I have tried Ubuntu 11.10 Beta 1 codename Oneiric Ocelot, which was launched a few days ago. Running it on my Sabily Badr 11.04 using Virtualbox SE programs. There is not much difference in the installation process compared to earlier versions, 11.04 Natty Narwhal. Its default wallpaper also same.
Here are some screenshots of Ubuntu 11.10 Beta 1 Oneiric Ocelot installation process.
1. Ubuntu 11.10 Oneiric Ocelot Beta 1 start.
Later we will look around and find the differences compared to previous versions Natty Narwhal 11.04.
