The most popular system language for an operating system is English when working as a system developer, but when it comes to writing document you probably need a local language spelling package. And in me previous blog I have written how to install swedish spelling package for LibreOffice, but with Ubuntu 12.10 there is a better way. Install the spelling checking package as debian package.
$ sudo apt-get install hunspell-sv-se
Afer installation you need to restart LibreOffice. Then you need to make LibreOffice aware of the the new spelling package. You do that by open Tools -> Options... -> Language Settings -> Writing Aids
Now you can change spelling checking for text or the complete document via Tools -> Language
