Put this line in terminal:
ibus-daemon -x -r -d
If you are a fan of GNOME Classic no effect as I am, here is a very good trick to add Shutter icon + Ibus Input icon to systray in Ubuntu.
Press Alt + Windows, right click on systray and click “Add to panel”. In the appeared list, choose “Notification Area”.
If Ibus is running and Shutter is running, they should appear there. Magnifique!
