As Kevin said, you must "translate" PO files into (binary) MO files. msgfmt utility (from gettext package) might be used to do that: $ msgfmt -o file.mo file.po Then, MO files should be put into /usr/share/locale/ta/LC_MESSAGES/ directory. Additionally, you need /usr/share/locale/ta/entry.desktop file. Without it, you won't be able to pick up Tamil from list of existing languages. Simplified file content is below: [KCM Locale] Name=Tamil Name[ta]=Tamil in Tamil On my system, localization files are owned by user root, group root, and have 644 permissions.
