I tried to build ibus-* packages. (Not all)
https://build.opensuse.org/project/show?project=home%3Aftake%3Aibus-14

ibus-hangul, ibus-pinyin and ibus-unikey failed to build.

Fortunately, the reasons are the same; the signatuire of the 
ibus_config_get_value function was changed.

Here is a patch for ibus-hangul:
https://github.com/choehwanjin/ibus-hangul/pull/3

Also we might find patches in Fedora project.


Note: ibus-anthy and ibus-mozc have no problem. (I'm using them)

Uhm...
Now the following xim.d/uim works on KDE4
but on GNOME, after first login, "ps -ef | grep uim" says:

geeko  1716  1679  0 01:04 ?   00:00:00 uim-xim
geeko  1717  1679  0 01:04 ?   00:00:00 [uim-toolbar-gtk] <defunct>
geeko  1745     1  0 01:04 ?   00:00:00 /usr/lib/uim/uim-helper-server

What is strange is that after log out and log in again, the systray is 
displayed successfully.

uim-toolbar-gtk3-systray is well integrated in GNOME3.

export XMODIFIERS="@im=uim"

export QT_IM_MODULE=uim

uim-xim &

Very simple patch!

I set variables like:
GTK3_IM_MODULE=xim
GTK_IM_MODULE=scim-bridge
XMODIFIERS="@im=SCIM"

It works fine for gedit (Gtk3, fall back to xim), firefox and chromium 
(Gtk2).

However, if I set "GTK_IM_MODULE=scim",
firefox outputs errors that are similar to:

I also found another patch here:
