linux input daemon "ibus"... solving problems Well how to fix " can't open preferences for ibus ibus preferences does'nt show " and other like this .... in my case when i click RMB on ibus -> preferences ... nothing happens ... the setup dialog is does'nt showed ___ then i try to open it by terminal (by typing "ibus-setup" WITHOUT sudo ) the setup dialog is still does'nt showed but i get error in terminal which seems so { (process:5541): Gtk-WARNING **: Locale not supported by C library. Using the fallback 'C' locale. Traceback (most recent call last): File "/usr/share/ibus/setup/main.py", line 585, in <module> locale.setlocale(locale.LC_ALL, '') File "/usr/lib/python2.7/locale.py", line 547, in setlocale return _setlocale(category, locale) locale.Error: unsupported locale setting } then one more error during Gir1.2-GTK-2.0 instalation there ALSO was something about errors in locales .... what helps me go to synaptic -> localizations mark locales lokales-all util-linux-locales Thats all, problem was solved this way, and ibus preferences works. I think it can be useful, for some italki users which learning asian languages. good luck in your studying! P.S. for those who don't knows, "Ibus" its a very useful programm, that allows you to type asian* characters from your keyboard! Instead of using different staff like sites with screen keyboards which is not so comfortable) * in my case i trying to set up korean characters input... but there is many different languages (even not only asian)
