Hey Gunnar,
  Thanks for looking further into this.

well that assumes that there is a hyphon in the name, while that is the case for the ones I know of, its not necessarily guaranteed. Thus:

"${XDG_CURRENT_DESKTOP##*:}" should be safer, GNOME (or Unity) should always be last since its essentially a fallback value

As expected, since we get the list of packages from language-selector-common using PackageKit

Does gnome-control-center need to create ~/.pam_environment? I didn't think that is used upstream, but specific to Ubuntu patched
accountsservice so maybe we will have to patch it for that?

This makes sense

It would be good to allow users the option of using fcitx (even if poorly integrated), however lets just get the default session working for now!

"ibus" seems most sensible to me also.

Title:
  ibus/im-config in Ubuntu GNOME

Status in Ubuntu GNOME:
  New
Status in gnome-control-center package in Ubuntu:
  Invalid
Status in gnome-session package in Ubuntu:
  New
Status in im-config package in Ubuntu:
  In Progress
Status in language-selector package in Ubuntu:
  In Progress

Bug description:
  In the gnome-language-selector one is able to set the "Keyboard input
  method system". For instance on my system I can either set it to
  "none", "IBus", or "fcitx". However there is no such option in the
  gnome-control-center's Region & Language section, though I think that
  there should be.
