IBus (Intelligent Input Bus) is an open source input framework for Linux and Unix.
Except for the basic IBus framework, one or more engines should be installed. For example:
emerge --ask app-i18n/ibus ibus-pinyin
Have a look at the eix output for more available engines:
eix -c ibus -I app-i18n
For graphical toolkit integration, app-i18n/ibus offers
gtk (this refers to gtk+:2) and
gtk3 flags. There is a separate app-i18n/ibus-qt package for Qt (including KDE) as well. Do not forget to install this latest package if KDE/QT is the main desktop environment for the system.
The app-i18n/im-chooser package can helpful for selecting the preferred input method. As of now all im-chooser packages in the Portage tree are marked unstable.
If nothing starts (no ibus daemon) when a user logs in, put the following in the ~/.xprofile file:
export GTK_IM_MODULE=ibus export XMODIFIERS=@im=ibus export QT_IM_MODULE=ibus ibus-daemon -drx
The installation can be finely tuned by running:
ibus-setup can be used to set the preferred input methods, the system keyboard, or to add an icon in the taskbar.
You may also use the command-line ibus utility, if you can't or don't want to use ibus-setup:
ibus engine m17n:t:unicode # For example
To inform Qt ibus is now the input method, run:
