It was stated that in gnome-shell 3.8+ was released integrated input method where i would not need to take care of setting up iBus and deal with enabling/disabling it every time.
Since i always use 3 languages one of which requires iBus i decided to give it a try in VirtualBox. So i've installed latest stable Ubuntu GNOME (13.04), added PPA for Gnome and did
apt-get update && apt-get dist-upgrade.
But seems that this announced feature doesn't work. I added needed languages and indicator-applet shows that i switch between them, but language requiring iBus (Chinese in this case) still uses standard layout and all i enter is just Roman characters.
Is there anything I am missing or have done wrong?
