17.10: No input method for CJK languages

This bug has been reported on the Ubuntu ISO testing tracker.

A list of all reports related to this bug can be found here:
http://iso.qa.ubuntu.com/qatracker/reports/bugs/1719938

I could reproduce this with the 2017-09-26 ISO.

$ cat /etc/default/keyboard
XKBLAYOUT=se
BACKSPACE=guess
$ gsettings get org.gnome.desktop.input-sources sources
[('xkb', 'se')]

However, IBus was up and running (as it should be for all users) and the necessary input methods had been installed. Hence I could go to "Region & Language", add the "Chinese (SunPinyin)" input source, switch to it, and instantly start typing Chinese characters.

But I suppose the idea is that some Chinese input method should be enabled to start with...

@Gunnar, here on an updated artful system only "chinese" is listed in the gnome-control-center interface, not "chinese (sunpinyin)" (after installing the chinese support from language-selector). The shell UI lists "chinese zh" but selecting it doesn't give access to ibus input method nor the completion UI and typing just gives a qwerty layout

ibus-sunpinyin is installed but in ibus-setup the input tab only lists french so it looks like ibus didn't get correctly setup by GNOME when selected

@Sebastien: What if you click "Chinese" in the input source GUI, then doesn't it expand to the actual input methods available? (That's what happened for me.)

Btw, I think you need to relogin (or possibly reboot) after having installed the Chinese language support, if those packages were not installed by the installer.

I verified on 16.04 both on the live session and an installed system there is an indicator to select the method of input when I select simplified Chinese in the list of languages. There is no input method selected by default but it's trivial to click on the indicator and select the one I want.

Right, so the current behaviour is not an Ubuntu bug but how current GNOME behaves. They believe it's not possible to "guess" what input method an user for a defined locale is going to need and don't want to have a cluttered menu with a bunch of options which the user is not going to need.

The recommended way to set it up on the installed system is to use gnome-initial-setup on first login (which we don't do in Ubuntu), that wouldn't resolve the installer/live cd cases though where the user is just going to need to use the settings to configure it.

That's not a simple fix but something we need to give more consideration to next cycle, I'm lowering the importance and unassigning, it's not likely we change anything for artful now.

@Jean-Baptiste: Can you please show us the output of these commands on a 16.04 Chinese install:

cat /etc/default/keyboard

gsettings get org.gnome.desktop.input-sources sources

cat /etc/default/keyboard
# KEYBOARD CONFIGURATION FILE

# Consult the keyboard(5) manual page.

XKBMODEL="pc105"
XKBLAYOUT="cn"
XKBVARIANT=""
XKBOPTIONS=""

BACKSPACE="guess"

gsettings get org.gnome.desktop.input-sources sources
[('xkb', 'cn'), ('xkb', 'us'), ('fcitx', 'pinyin')]

Before artful, unity-settings-daemon (based on gnome-settings-daemon) setup input sources by locale.
http://bazaar.launchpad.net/~unity-settings-daemon-team/unity-settings-daemon/trunk/view/head:/plugins/keyboard/gsd-keyboard-manager.c#L505

However already commented, this code in gnome-settings-daemon are replaced by gnome-initial-setup.
https://github.com/GNOME/gnome-settings-daemon/commit/912c41a1b729d635d3b335c87653141781e9be9e

If Ubuntu doesn't use gnome-intial-setup, should be engine_from_locale() reindroduced?

Status changed to 'Confirmed' because the bug affects multiple users.

Reverting that change for artful makes sense yes

I created patch. This patch will fix but #1514544 too.
Building patched package is completed successfully. I'll test the package after tomorrow.
