A normal OpenOffice.org installation (aptitude install openoffice.org) does not install the spell checking capabilities. To install:
- Install these packages: aspell, aspell-en, ispell, myspell-en-us, openoffice.org-thesaurus-en-us
- To have “check-as-you-type” feature (the red curvy lines indicating wrong spelling), go to Tools=>Options=>Language Settings=>Writing Aids and in the options, check the option “Check Spelling As You Type”
