I have tried to autostart the
ibus daemon upon logging in using the script:
ibus-daemon --xim --replace --daemonize --panel=/usr/lib/ibus/ibus-ui-gtk3
but it does not happen.
However, if I execute the script after I login, I am able to get the daemon running as usual.
This is something I can live with, but I am seeking a solution, if there is one, for autostarting to work.
