I want to use ibus-unikey or fcitx-unikey to type Vietnamese
I have set up the input method, etc... and reboot several times but neither ibus nor fcitx work.
Is your problem fixed ?
I have some tips for you. Choose only 1 language (english) for System Keyboard Layouts, configure iBus and let it uses system keyboard layout
Choose the input method switch and make ibus as the choice.
A dialalogue box to restart X session appears choose ok.
Log out and login back to restart X session.
Go to ibus system tray icon choose preferences
click input method tab and your language option
choose them to the add to list .---done---
