The solution given was to edit /etc/X11/xinit/xinput.d/scim and change
the xim references to scim.
This is just plainly misinformed suggestion. Ubuntu also ships the
scim-immodule setting, the proper way has always been using im-switch,
instead of changing the configurations file. I've seen such suggestions
given elsewhere, I just don't have time to correct it every time I see
it.
This is a good option, however for reasons stated above I would rather
have the user use the scim-kmfl im-switch file rather than the scim
im-switch file. But I am open to suggestions.
I can guarantee that scim package's im-switch setting won't change
randomly. And when it changes, upgrade path will be provided so that
packages that depend on it won't break.
I think as the maintainer, it's eventually your decision (and your
sponsor's decision) to make. But I'll just make it clear that I'm very
against the idea of SCIM IM engine packages shipping their own im-switch
settings.
