====默認不支持中文
# pacman -S ibus
# pacman -S ibus-qt
$ pacman -Ss ^ibus-* //查看所有可用的輸入法：
# pacman -S ibus-libpinyin
# pacman -S ibus-googlepinyin
啟動
$ ibus-setup
現在運行ibus-setup的初始程序(當要用Ibus的用戶):
IBus has been started! If you cannot use IBus, please add below lines in $HOME/.bashrc, and relogin your desktop.
（譯：IBus已啟動！如果您還不能用Ibus,請您先將以下的三行代碼加到$HOME/.bashrc，再重新登錄。)
export GTK_IM_MODULE=ibus
export XMODIFIERS=@im=ibus
export QT_IM_MODULE=ibus
注意: 雖然Ibus使用一個后台程序，但是它不是被systemd管理的那種后台程序：普通用戶也可以運行，當你登錄時，它會啟動。
注意: 但是，如果ibus尚未啟動，先將那些"export"的代碼復制到$HOME/.xprofile，並將這行代碼加到該文件：“ibus-daemon -x -d”,再重新登錄。
ibus-daemon -x -d
