This does work after all. The thing to note here is that Gnome
integrates ibus, so the manual use of ibus-daemon and ibus-setup is not
guaranteed to work when using Gnome.
Instead the Region settings should be used. It is important to remove
any residual ibus state, including the ibus registry at
.cache/ibus/bus/registry.
This all worked fine once I removed ibus and ibus-libpinyin from the
user profile and cleared all ibus state in my home directory.
This command
dconf dump /org/gnome/desktop/input-sources/
should indicate that the “sources” key contains the pair “('ibus',
'libpinyin')”.
