In oneiric(GTK3) environments, environment variable "GTK_IM_MODULE" always set as "xim", not "ibus".
[How to reproduce]
0) install ibus, and/or clean install with any language that need IM subsystem(such as Japanese, Chinese, Korean, Frence..etc.).
1) log-in Oneiric.
2) variable GTK_IM_MODULE set as ibus.
You will see in terminal:
$ export | grep GTK_IM_MODULE
[expect results]
When we have /usr/lib/gtk-*.0/*/immodules/im-ibus.so(In Unity environment, that provide as default), using ibus (GTK_IM_MODULE=ibus)
[actual results]
always use xim (GTK_IM_MODULE=xim)
[side effects by this problem]
Some IM system needs "candidate" window, that layout by {xim, ibus} modules.
For historical/technical reason, XIM does not provide enough support about coordinating candidate window, as a result, candidate window show in inconsequence place. That breaks Desktop UX.
[analysis]
That problem caused by /etc/X11/xinit/xinput.d/ibus .
This scripts has bad glob coding as follows:
-------------------------------------------------------
$ cat /etc/X11/xinit/xinput.d/ibus
(..snip..)
if [ -e /usr/lib/gtk-*.0/*/immodules/im-ibus.so ]; then
GTK_IM_MODULE=ibus
else
GTK_IM_MODULE=xim
fi
(..snip..)
-------------------------------------------------------
In GTK2/GTK3 dual-stack environments, this glob pattern matches two files(see below). test(1) does not support multiple operand, that will fail with error message "[: 7: /usr/lib/gtk-2.0/2.10.0/immodules/im-ibus.so: unexpected operator", and set GTK_IM_MODULE=xim.
-------------------------------------------------------
$ ls /usr/lib/gtk-*.0/*/immodules/im-ibus.so
/usr/lib/gtk-2.0/2.10.0/immodules/im-ibus.so
/usr/lib/gtk-3.0/3.0.0/immodules/im-ibus.so

Good case(GTK_IM_MODULE=ibus) : https://launchpadlibrarian.net/76880967/01_ibus_valid.png
Bad case (GTK_IM_MODULE=xim) : https://launchpadlibrarian.net/76881006/02_xim_invalid.png
