And #Ubuntu 11.10 Installed

Here it is. After upgrading with $sudo update-manager -d , all worked as expected.
Ubuntu 11.10 running
Note that there is no screensaver by default.
And the nvidia settings are gone. However, the new launcher of Unity is great. Fast and more features. You can sort between categories and searching files is a breeze now.
Avidemux was removed during the installation. Expect to see this coming back, soon. I'll guess not all components are ready for it to run. So it will hopefully come back in no time.
