When you run the OLPC software you currently have access only to the English locales.
If you want to enable Greek support, you need to run (as root)
localedef -v -c -i /usr/share/i18n/locales/el_GR -f UTF-8 /usr/lib/locale/el_GR/
localedef -v -c -i /usr/share/i18n/locales/el_GR -f UTF-8 /usr/lib/locale/el_GR.utf8/
You will get a bunch of warnings. You can ignore them for now.
The localedef command compiles the source locale information found at /usr/share/i18n/locales/el_GR and places the resulting files at
/usr/lib/locale/el_GR/ and /usr/lib/locale/el_GR.utf8/ (both directories contain the same files, so you can also make a link from one to another). The reason we make two versions is that we can use either el_GR or el_GR.utf8 in the applications. Both use UTF-8 as the base encoding which is always nice.
For other locales, replace el_GR with the locale name of your country.
To activate the Greek locale, you need to create a file /etc/sysconfig/i18n and add the text
Now you need to place the translated applications (.mo format) into
and restart your virtual machine (or laptop (hint hint)).
