I'm unable to get IBus working in 14.04. The system tray never shows the keyboard icon or the IBus icon, even though "Show icon on system tray" is checked in the IBus preferences dialog. I can hit Ctrl-Space as often as i want, nothing happens. I also tried defining a different shortcut to change languages - to no avail. Finally, I also installed language-selector-gnome, and made sure that IBus is selected as "Keyboard input method system". What else can I try? Thanks!
