Japanese input on linux

Here's something I always forget: how to setup Japanese input on the X server in linux *ouch* Every website I visit gives a complicated list of "you can do it this way, or that, or if you type this here, you get this, etc." Well, here it is in 4 easy steps:

1. install freewnn-jserver
2. install kinput2-wnn
3. in .xsession or /etc/X11/Xsession , set XMODIFIERS="@im=kinput2"
4. set LC_ALL="ja_JP.EUC-JP"

If you have trouble, google with the following keywords:
freewnn kinput2 XMODIFIERS

Enjoy!
