Background information: Debian Jessie (8.7) LXDE Desktop Environment.
fonts-unfonts-extra packages installed (so I can view Korean characters).
Right now I can view and type English (US) of course since I setup Debian using English (time zone set to Korea of course). But, I also want to be able to type Korean (English as main language, Korean secondary). I have tried using "Keyboard Layout Handler", but unchecking "Keep system layouts" and adding Korean language does not work. To switch to Korean I tried moving "KR" up in the "Keyboard Layouts" section in "Keyboard Layout Handler". And setting the keyboard shortcut toggle and using that. I still can't type Korean (only English).
How do I type English and Korean (switch between them and set English as main language if possible)? Any help is appreciated! Thanks!
