I am trying to setup Mozc or Anthy, as long with English alternative.
So far I have tried severals methods:
Complete purge/reinstall of the languages support that I need.
Complete purge/reinstall of ibus.
Replace of im-config by the im-switch.
After that, purge of im-switch and reinstall of ubuntu-desktop...
fcitx-mozcinput method instead of ibus.
And many minor editing/tweaks like adding iBus to startup programs,
Now, I am able to change the language using (Crtl+Space) and it work perfectly when I test it inside the launcher (using super/windows key).
The same goes for Anthy and English alternative.
However, when I try to use it in anywhere else, the language icon became gray and I cannot get any Japanese character working.
I know (and I am following some) that there are some bug related problems involving Japanese and language/text entry, but I am not sure if they apply to my case since I have it working in some places.
Also, I suppose that even if it is a bug, there may be at least some kind of work around (and I tried some available in Ubuntu - Launchpad with no success other than the mentioned above) since its unlikely that Japanese is no longer supported in Ubuntu.
Because of that, other than suggestions like copy/paste from the launcher, is there any procedure that you can recommend in order to fix this problem?
From the moment I would like to have it working at least for Firefox and for some text editor (vim or geany if possible).
By the way, from the responses presented in the similar questions in this site, I had tried almost all that appears to be correlated with my problem/Ubuntu version.
