Everybody posts about applications to install after upgrading to Ubuntu 9.10 Karmic Koala. I'm not saying they are not interesting, I'll even post some links to such posts from other blogs (look at the bottom of the post) I really liked, but to get there, you must firstly fix everything that's not working for you, tweak some things and so on.

Fixes / tweaks in this post: fix the Internet connection, change Ctrl + Alt + Backspace behaviour, tweak update manager behaviour, disable the login sound, enable icons in menus and buttons, make Nvidia Settings save changes to xorg.conf, fix the popping sound, Firefox scrolling issues fix, make the Super Key bring down the Applications menu, change notify-osd behaviour.
