Title:
Let im-config back off if IBus on GNOME desktops
Status in im-config package in Ubuntu:
Fix Released
Status in im-config source package in Focal:
In Progress
Bug description:
Note:
Quite a few ibus crash bug reports have been marked as duplicates of this
bug. If you find that such a bug was not actually addressed through the fix of
this bug, please feel free to comment on the bug report and remove the
duplicate link.
[Impact]
GNOME desktops have built-in mechanisms for launching and configuring
IBus. However, up to now im-config has overridden GNOME in this
respect, resulting in a slightly different command for launching IBus
and a few extra environment variables; most importantly GTK_IM_MODULE
has been set to "ibus".
This was recently changed via im-config 0.45-1 in groovy, where im-
config does not do anything in case of IBus on a GNOME desktop. A
positive side effect of the change is that the frequency of IBus
crashes has been significantly reduced.
No deep analysis has been carried out which explains *how* this change
prevents IBus crashes. The basis for the conclusion is instead
statistics from errors.ubuntu.com. Some relevant links can be found in
this discourse topic:
https://discourse.ubuntu.com/t/ibus-no-more-gtk-im-module-ibus/17727
[Test case]
We have not been able to reproduce the crashes, so a simple test which
verifies the fix can't be accomplished. Instead we need to be
attentive to possible regressions.
* On an Ubuntu desktop, install ibus-libpinyin and ibus-hangul.
* Log out and log in again (to an X session).
* Enable Intelligent Pinyin and Hangul (from Settings
-> Region & Language)
* For each of Intelligent Pinyin, Hangul, and the on screen
keyboard:
- Confirm that inputting works without hassle
- Do so on various apps: FF, TB, gedit, LO.
[Regression risk]
Even if we have done it differently in Ubuntu (and Debian), the GNOME
mechanisms we now let replace im-config with respect to IBus is mature
code which has been in use for quite some time on other distros. That
speaks for a low regression risk.
