I concur with Martin's point: The Language Selector's second tab does update /etc/default/locale $LANG to the new language.
This is sufficient to enabling iBus, if you follow the right steps. The result is that unity-2d Search box (and elsewhere) supports iBus through the UI, as follows: In Language Support: * Tab 1: Install Chinese/Simplified translations, input methods, and fonts * Tab 1: Apply System-Wide button * Tab 1: Select iBus in Keyboard Input Method System combo. * Tab2 (named "Regional Formats" in en _US"): Select Chinese and Apply. * Reboot/Relogin * Ctrl + Space enables /disables iBus It is arguably a UI design issue that one needs to separately enable input methods after already doing these steps: A) Language tab > install/Remove Languages button > Input Methods checkbox B) Language tab > Keyboard input method system combo > ibus selection Enabling input methods also seems somewhat hidden since it occurs on Region Formats tab, whose text discusses Number, Date and Currency formats but that does not mention input methods. ** Changed in: unity-2d Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/663776 Title: Search dialog can not support iBus -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
