I'm tri-language myself and can't configure ibus in recently installed Beefy Miracle.
I'm using RU+EN+JP (Anthy) and whenever i switch from RU to JP, ibus doesn't catch my input so i can't type japanese. This is probably bug in ibus, but here is more:
Then i try to remove layouts other than Anthy in ibus-setup, settings resets back to default (all using languages) after relogin.
I've installed iBus and ibus-mozc, an input method engine of Japanese, from the repository, and attempted to enable mozc from Preference > "Input Method" tab > "Select Input Method" combo box.
However, there is no choice to select, so I couldn't enable mozc.
I also tried ibus-anthy, another legacy Japanese input method, but the situation was the same and I couldn't use anthy.
My Chrome version is 31.0.1650.63. After the upgrade to 13.10 I struggled to get the Anthy (iBus) input back and working. I thought I had at last but now I discovered that it works pretty much everywhere in Ubuntu, including Skype, which was a problem discussed in another thread, but not in Chrome.
Today I installed Statler A2 and tried the new input method named 'iBus'. http://code.google.com/p/ibus/Its configuration was much easier than SCIMs (I use Chinese Pinyin input) and was installed in short time.
I've installed ibus-anthy for Japanese input. It works fine, and the anthy menus are beautiful in gnome. My problem is that I can't figure out how to get the tray icon to appear, even though I have the "show tray icon" bit checked in the ibus prefs. The default ctrl-space shortcut to switch keyboards also isn't working for me.
