I've been trying to get the latest release of PCLOS to accept Japanese input. First, I made the changes that I explained here. Basically, you have to download the required packages and add these lines to the file i18n:
I did that using the command
export $ (dbus-launch)
to edit the files with Konsole, as I had also explained here once.
I also installed Abiword (as it helped me once to test SCIM) and removed the LibreOffice KDE integration package, which has prevented me to fire up SCIM both in Mandriva and Mageia. Then I followed the detailed directions for PCLOS here.
However, after trying this process in PCLinuxOS 2013.02, all I achieved was to freeze the desktop when attempting to launch any application.
Today I found the culprit and fixed the problem. In
you have to open the file Xsession, to which you will append the following lines before the line that starts with exec
export XIM_PROGRAM="scim -d"
The problem was that the first line must read xim at the end, not SCIM, as I had detailed before.
By the way, remember that PCLOS shows the IME on demand. You have to press CTRL + space to work with it. 日本語がきっと書けますよ！
Oh, and the best part of this method is that Japanese IME also works with Firefox.
I wonder if this can be applied to Mageia/Mandriva to enable Japanese in Firefox...
I'll try that tomorrow.
