Horms recommande l'utilisation des paquets uim-xim, uim-anthy et uim-gtk2.0 à la place de kinput2 avec cannaserver (ainsi que im-ja et wnn). Ça marche pour les applications gnome, Mozilla Firefox et Eterm.
I also made sure that uim-xim is running and that following the XMODIFIERS and GTK_IM_MODULE environment variables are always set. If you have a .xession, just add this sinppit in there before your window manager runs.
uim-xim& MODIFIERS=@im=uim GTK_IM_MODULE=uim
To configure uim-anthy run uim-pref-gtk. This also provides a list of what key combinations are used to do conversions.
