Things to do after a "fresh" install of Ubuntu 11.10
Also, there are nice notes at techdrivein.com
Update!
sudo apt-get update sudo apt-get upgrade
Restricted extras
Media formats etc.
sudo apt-get install ubuntu-restricted-extras
Compiz config settings manager
sudo apt-get install compizconfig-settings-manager
Enable GetDeb ppa
Provides fresher versions for certain apps (might be less stable, but fix some bugs). Read more here.
Automatic install: go to http://archive.getdeb.net/install_deb/getdeb-repository_0.1-1~getdeb1_all.deb
Alternative manual install: add the following to your /etc/apt/sources.list
deb http://archive.getdeb.net/ubuntu oneiric-getdeb apps
Then add the repository GPG key:
wget -q -O- http://archive.getdeb.net/getdeb-archive.key | sudo apt-key add - sudo apt-get update
You could do similar thing for playdeb, if you are into games.
Then you can go to the http://www.getdeb.net/updates/ubuntu/11.10/ and install what you want by clicking on the screenshots of the applications.
XBMC media center
It is like MythTV, good for HTPC use.
At the moment there is no stable version for 11.10 in the xmbc ppa, but there is another place to get it:
sudo add-apt-repository ppa:nathan-renniewaldock/xbmc-stable sudo apt-get update sudo apt-get install xbmc
