[Oneiric] ibus does not register as IM_MODULE in GTK, GTK_IM_MODULE is always "xim"

Bug Description

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.
      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

    That breaks Desktop UX for.


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
if [ -e /usr/lib/gtk-*.0/*/immodules/im-ibus.so ]; then


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

It looks rational. The patch works fine for my test environment. Thank you!

I've adjusted the patch slightly; your patch would leave GTK_IM_MODULE unset if ibus-gtk3 is installed and ibus-gtk is not, but we want to set it to xim in this case.

Thanks for helping to get this fixed!

This bug was fixed in the package ibus -

ibus ( oneiric; urgency=low

  * debian/xinput/ibus: check for GTK2+ and GTK3+ IMModules separately,
    otherwise the file globbing fails us. Thanks to Ikuya Awashiro
